Sourcing foreign inputs to improve firm performance

A new article at VoxEU.org by Maria Bas and Vanessa Strauss-Kahn opens by asking
Should trade policy fight or promote imports of intermediate inputs?
The answer is, of course, neither, the decision about what inputs a firm should use and where they should get them from is up to the firm, not policy makers.

That said, it is certainly true the effect of foreign intermediate goods on firm productivity and export behaviour is not without economic and (unfortunately) political interest. Bas and Strauss-Kahn write,
There are several mechanisms through which foreign inputs could affect firm competitiveness and export performance.
  • The first mechanism is the complementarity channel. By accessing new varieties of intermediate goods, firms expand the set of inputs used in production and reach a better complementarity between them. These complementary gains result from imperfect substitution across intermediate inputs and lead to increased firm efficiency. This allows more firms to access export markets and/or to export more varieties.
  • The second channel is related to an input cost effect. Importing cheaper intermediate inputs increases firms’ competitiveness, boosts expected export revenues, and allows more firms to enter the export markets.
  • A third mechanism is foreign technology transfer. International trade promotes economic growth through the diffusion of modern technologies embodied in imported intermediate inputs. Technology transfer is also related to quality transfer – imports of high-quality intermediate inputs lead to exports of high-quality goods. Firms may access new export markets with better quality/technology products, or export more varieties to existing markets.
Imports of intermediate inputs thus allow firms to access a bigger range of inputs, including more sophisticated or lower-cost ones, resulting in higher firm productivity and export scope (i.e. the number of varieties exported).
Bas and Strauss-Kahn then turn to look at evidence from French firms.
In recent work (Bas and Strauss-Kahn 2014), we present evidence from French firms involved in international trade, and reveal that these mechanisms are important drivers of firms’ export patterns. French firms importing more varieties of intermediate inputs over the 1995–2005 period (the average firm adds four varieties of imported inputs) have increased their productivity gains by 2.5%. By enhancing productivity, importing more input varieties also raises firms’ export scope – firms are more likely to bear the fixed costs of exporting, and to survive in competitive export markets.

Direct channels are also at play – controlling for productivity gains, a 10% increase in the number of imported input varieties results in a 10.5% expansion of firm export scope. The average firm, by importing four additional varieties of inputs, increases its exports by 2.7 varieties.

The input cost effect and the foreign technology/quality transfer channel are distinguished by looking at the country of origin of imported inputs. The rationale behind this strategy lies in the principle that developed countries produce goods with high technology/quality content, whereas developing countries provide low-price inputs. In the case of French exporting firms, foreign inputs from the most advanced economies have the strongest effect on firm productivity. Concerning export scope, both imported inputs from developed and developing countries help raise the number of exported varieties.

Overall, French firms benefit from importing intermediate goods, as it fosters both their productivity and exports. These results shed some new light on the debate on the benefits and costs of trade integration. The positive role of imported inputs in the economy should be acknowledged and accounted for.
So the importing of intermediate inputs helps both productivity and exporting.

Paul Zak on Trust, morality — and oxytocin?

From TED talks comes this video (recorded at TED Global, July 2011, in Edinburg, Scotland. Duration: 16:35) which asks the question, What drives our desire to behave morally? Neuroeconomist Paul Zak shows why he believes oxytocin (he calls it "the moral molecule") is responsible for trust, empathy and other feelings that help build a stable society.

What’s behind the human instinct to trust and to put each other’s well-being first? When you think about how much of the world works on a handshake or on holding a door open for somebody, why people cooperate is a huge question. Paul Zak researches oxytocin, a neuropeptide that affects our everyday social interactions and our ability to behave altruistically and cooperatively, applying his findings to the way we make decisions. A pioneer in a new field of study called neuroeconomics, Zak has demonstrated that oxytocin is responsible for a variety of virtuous behaviors in humans such as empathy, generosity and trust. Amazingly, he has also discovered that social networking triggers the same release of oxytocin in the brain -- meaning that e-connections are interpreted by the brain like in-person connections.

A professor at Claremont Graduate University in Southern California, Zak believes most humans are biologically wired to cooperate, but that business and economics ignore the biological foundations of human reciprocity, risking loss: when oxytocin levels are high in subjects, people’s generosity to strangers increases up to 80 percent; and countries with higher levels of trust – lower crime, better education – fare better economically.

He says: "Civilization is dependent on oxytocin. You can't live around people you don't know intimately unless you have something that says: Him I can trust, and this one I can't trust."

Shackle on economics

From the forward to the paperback edition of "The Years of High Theory: Invention and Tradition in Economic Thought 1926-1939".
Economics is one of the strangest items in mankind's intellectual cupboard. The styles of thought exemplified in its literature range from mathematics of a purity to which observational data are quite alien, through measurement-procedures which are culinary and gastronomic in their fascination, to the treatment of the subject as a branch of philosophy and, finally, to its use as the material of literary art. All these styles are expressions of humanity's untrammelled imagination and creative urge. Each in its own way is a form of art, and in each we may truly discover beauty.
I'm sure only an economist could write such a thing!

Was the Fed a good idea?

This is the question considered in a series of papers in the latest issue (Volume 34, Number 2 Spring/Summer 2014) of the Cato Journal.

Passed on December 23, 1913, the Federal Reserve Act was designed to provide an elastic currency that would respond to the needs of trade. Today, the Federal Reserve System is much different than it was a century ago. How well has the Fed performed? Was the Fed a good idea? Can we do better?

The Editor's Note introduces the various papers:
The Federal Reserve Act was passed on December 23, 1913. It was designed to provide an elastic currency that would respond to the needs of trade. There was nothing in the Act about price stability, interest rates, or full employment. The expectation was that the United States would continue to define the dollar in terms of gold, and that the operation of the international gold standard would ensure long-run price stability.

It was widely accepted that “the highest moral, intellectual, and material development of nations is promoted by the use of money unchanging in its value,” as declared by the U.S. Monetary Commission of 1876. The classical gold standard ended with the First World War, and, in August 1971, the dollar became a pure fiat money when President Richard Nixon closed the gold window.

Today the Federal Reserve System is much different than a century ago. How well has the Fed performed? Was the Fed a good idea? Can we do better? To address those and related questions, the Cato Institute brought together some of the most respected monetary scholars and policymakers at its 31st Annual Monetary Conference in Washington, D.C., on November 14, 2013. The papers from that conference are featured in this volume.

In the lead article, Charles I. Plosser argues for a rules-based monetary policy and a “limited central bank” devoted to the primary task of safeguarding the dollar’s long-run purchasing power. Jerry L. Jordan considers the lessons learned from a century of U.S. central banking, while George A. Selgin provides a detailed account of how the Fed has twisted its true record. Athanasios Orphanides, like Plosser, makes a strong case for a “price stability mandate.”

Lawrence H. White examines the Fed’s “troubling suppression of competition from alternative monies” using the examples of the liberty dollar and e-gold. Legal restrictions are also noted by Richard H. Timberlake in his article on “clearing house currency.” Scott B. Sumner advocates rules rather than discretion in the con duct of monetary policy. His preferred rule is to target nominal GDP rather than inflation or the price level.

Since the Panic of 2007, the Fed’s balance sheet and power have expanded dramatically. The Fed’s ultra-low interest rates and quantitative easing have distorted capital markets, increased risk taking, politicized credit allocation, monetized government debt, and allowed the government to expand its size and scope. Moreover, the Fed’s regulatory powers have increased uncertainty and dampened the disciplinary forces of private free markets.

Rep. Jeb Hensarling, the chairman of the House Financial Services Committee, pledges to conduct hearings to hold the Fed account able and help improve its performance. John A. Allison draws on his experience as chairman and CEO of BB&T Corporation to discuss the unintended adverse consequences of top-down financial regulation as opposed to the spontaneous positive results of market-based discipline, given the appropriate institutional framework making individuals responsible for their actions. Kevin Dowd and Martin Hutchinson look at the institutions that helped mitigate moral hazard and harmonize financial markets in the pre-Fed era and compare them to changes in the financial architecture since the creation of the Fed. Their main conclusion is that competitive markets bound by laws of contract and an overarching rule of law that protects private property rights provide incentives to manage risk and avoid the problem of “too big to fail”—a central bank and hordes of government regulators do not.

Rep. Kevin P. Brady, chairman of the Joint Economic Committee, makes the case for a bipartisan Centennial Monetary Commission to examine the Fed’s history and consider alternatives to pure discretionary government fiat money. He takes seriously the constitutional mandate for Congress to ensure stable-valued money. Gerald P. O’Driscoll Jr. considers the prospects for fundamental monetary reform and the strategies to promote such reform. R. David Ranson argues that the Fed’s over reliance on conventional statistics to guide its policy and its politicization have led to failed policies. In particular, by distorting interest rates and trying to “stimulate” the economy, the Fed has actually slowed recovery. Ultimately, real reform of the monetary and financial system requires that voters understand the limits of central banking and the benefits of limited government and free markets.

In the final article, Lewis E. Lehrman, a member of the President Ronald Reagan’s Gold Commission in 1981, makes a compelling case for returning to a classical gold standard, not only to protect the purchasing power of the dollar but to prevent the federal government from using the printing press to pay its bills.

Economists and firms

A few days back Donal Curtin posted a piece at the Economics New Zealand blog on raising productivity in the services sector. A one point he writes,
Maybe economists aren't the best people to investigate business management - with exceptions (eg Baumol, Varian), economists tend to see the business production function as a "black box" with inputs in and outputs out, and they don't typically take the lid off the box - but this looks to me like one of the more likely keys to fit the productivity paradox lock.
I have to say that, in the past at least, he has a point. Economists for many years simply didn't see the workings of the firm as an area they should be bothered with. Arthur Pigou (he of the tax) famously once wrote:
“[ ...] it is not the business of economists to teach woollen manufacturers to make and sell wool, or brewers how to make and sell beer, or any other business men how to do their job. If that was what we were out for, we should, I imagine, immediately quit our desks and get somebody - doubtless at a heavy premium, for we should be thoroughly inefficient - to take us into his woollen mill or his brewery”
While Lord Robbins thought that
“[t]he technical arts of production are simply to be grouped among the given factors influencing the relative scarcity of different economic goods. The technique of cotton manufacture [ ...] is no part of the subject-matter of Economics [ ...]”
As to why the firm was ignored in Austrian economics Witt writes,
“[t]he neglect of the firm as the organizational form of an entrepreneurial venture has a tradition in Austrian economics. It may be traced back to a characteristic of the scientific community in the German language countries. There, economic theory (Volkswirtschaftslehre) and business economics (Betriebswirtschaftslehre) were institutionally segregated as early as at the turn of the century to a degree still unknown today in the Anglo Saxon world. As Lachmann once conjectured, Austrian writers therefore considered the organizational form of entrepreneurial activities to be a topic best left to their business economics fellows”
And if one looks at the history of economic one finds little, if any, interest in the firm. When reviewing the contribution of the old institutionalists to the theory of the firm Hodgson writes,
“[ ...] we search in vain for a well-defined ‘theory of the firm’ within the old institutional economics”.
With reference to the German historical school Le Texier explains
“[m]embers of the German historical school such as Gustav von Schmoller analysed at length the birth and growth of the business enterprise, but they were more historians than economists. None of these thinkers proposed a theory of the business firm”
About the work of Joseph Schumpeter, Hanappi says
“[a] well-defined theory of the firm thus cannot be found in Schumpeter’s oeuvres”.
As to Austrian economics Per Bylund writes,
“[b]ut despite the focus in Austrian economics on [ ...] “mundane economics,” and the fact that “the Austrians [have] so many necessary ingredients for a theory of the firm” [ ...], there is no Austrian theory of the firm”
and
“[w]hereas the theory of the firm has been a neglected area of study in mainstream economics, it has been missing from the Austrian economics literature”.
In the mainstream of economics up until around 1970 the standard theory of the firm was the neoclassical theory which as Donal notes treated the firm as a "black box", a production function or production possibilities set, a means of transforming inputs into outputs with no one asking how the transformation took place.

Since the 1970s, however, things have started to improve. During the 1970s work by Oliver Williamson Alchian and Demsetz and Jensen and Meckling started an upswing in interest in the firm as an significant economic institution. Today one only has to consider works like the "Handbook of Organizational  Economics", edited by Robert Gibbons and John Roberts, Princeton: Princeton University Press, 2013, to see that the firms and their inner workings are taken much more seriously. There are 1200 pages of people at least trying to take the lid off the "black box".

So I would suggest that there are good reason for letting economists, among others, investigate business management.

Given the concern with productivity of firms an additional area of investigation would be the relationship between firms and entrepreneurs. It is, after all, entrepreneurs who innovate and force change in business practises as well as in production techniques of goods and services. One only has to think of the effects of 'just in time' manufacturing to see how organisational change can affect costs and productivity.

The relationship between the theory of the firm and the theory of entrepreneurship is not as yet well understood but process is being made even here as witnessed by the Foss and Klein book "Organizing Entrepreneurial Judgement: A New Approach to the Firm", Cambridge: Cambridge University Press, 2012 (see this previous post) or Daniel Spulber's book "The Theory of the Firm: Microeconomics with Endogenous Entrepreneurs, Markets, and Organizations" , Cambridge: Cambridge university Press, 2009.

Incentives matter: manager file

A new paper forthcoming in the Scottish Journal of Political Economy. "Base Salaries, Bonus Payments, and Work Absence among Managers in a German Company" by Christian Pfeifer. The abstract reads:
This paper provides scarce insider econometric evidence on the structure of management compensation and on the incentive effects of fixed base salaries and bonus payments. Six years of personnel data of 177 managers in a German company are analyzed with special emphasis on the highest achievable bonuses under a Management-by-Objectives (MBO) incentive scheme. The main finding of panel negative binomial regressions is that higher achievable bonus payments are correlated with fewer absent working days, which supports the incentive effect of performance pay for managers. The fixed base salary component is, however, not significantly correlated with managers’ work absence. (Emphasis added.)
So if you give people a reason to be a work, they are at work. Seems reasonable.

The Economics of World War I

For the history buffs among you here is an interesting collection of papers on "The Economics of World War I". The collection is from VoxEU.org and it has been put together to commemorate the centenary of the outbreak of the First World War. Over the coming gyear Vox will be publishing a series of articles on the economics of the conflict itself, as well as on its causes and consequences. These will eventually be published in a Vox eBook.

Thus far there are four articles available:
Financial preparations leading up to WWI
Harold James, 8 July 2014
The 1907 panic emanated from the US but affected the rest of the world and demonstrated the fragility of the whole international financial order. The aftermath of the 1907 crash drove the then hegemonic power – Great Britain – to reflect on how it could use its financial power. There is a close link between the aftermath of a great financial crisis and the escalation of diplomatic tensions that led to war in 1914.

Changes in migration policies after 1914
Drew Keeling, 23 June 2014
The war declarations of August 1914 spelled far-reaching alteration to the fundamental character of modern long-distance international mass migration. For most of the preceding century, in the majority of big economies international human relocation had been largely peaceful, voluntary, and motivated by market incentives. Since 1914, it has been mostly shaped by politically determined quotas and legal restrictions, or driven by flight from war, oppression or similarly fearsome dangers and disasters

Four myths about the Great War of 1914-1918
Mark Harrison, 2 June 2014
As its centennial approaches, the events of the Great War have worldwide resonance. Most obviously, is China the Germany of today? Will China’s rise, unlike Germany’s, remain peaceful?

Height of World War I servicemen
Timothy J Hatton, 8 May 2014
The last century has seen unprecedented increases in the heights of adults. Among young men in western Europe, that increase amounts to about four inches. On average, sons have been taller than their fathers for the last five generations. These gains in height are linked to improvements in health and longevity.

Kirzner on Rothbard

Peter Boettke at the Coordination Problem blog points us to this short video of Israel Kirzner discussing the work of Murray Rothbard. In particular Kirzner notes Rothbard's blurring of the lines between his economics and his libertarianism.

Interview: Nicolai J. Foss and Peter G. Klein on “Organizing Entrepreneurial Judgment”

Nicolai Foss and Peter Klein are interviewed on the contents of their 2012 book “Organizing Entrepreneurial Judgment: A New Approach to the Firm”. The book is worth the time to read.

A brief discussion of the Foss and Klein book can be found in Section 3.2 of  "Contracts, Entrepreneurs, Market Creation and Judgement: The Contemporary Mainstream Theory of the Firm in Perspective". Journal of Economic Surveys, forthcoming.

A few questions:
Question: The aim of your book is, as you state, to define a program for research in the intersection of the theory of the firm and entrepreneurship. What is wrong with current theory in these fields?

Klein: Until the 1980s, the economic theory of the firm was a branch of neoclassical production theory. “Firms” were highly stylized, abstract units that convert inputs into output – everything economically relevant about the firm could be expressed as a production function. There was little interest in why firms exist, how firms are governed and managed, why some firms perform better than others, and so on. Any behaviors not consistent with “perfect competition” were regarded as efforts to exploit monopoly power. Basically, the theory had little to do with business firms as they actually exist.

Things got better with the emergence of agency theory, transaction cost economics, and the economic analysis of property rights. Even these approaches, however, are fairly static and “closed,” with little room for entrepreneurship and uncertainty. There was a standalone academic discipline of entrepreneurial studies, but it was mainly descriptive and focused on startup companies and self-employed individuals. Even today, the theory of firm doesn’t incorporate entrepreneurs, and much of entrepreneurship theory abstracts from the firms that entrepreneurs establish and operate.

Question: What are those “neglected insights” you want to revitalize?

Foss: In this book we pick up on a number of themes associated with less conventional thinkers in economics, notably Frank Knight and his seminal book, Risk, Uncertainty and Profit from 1921. In fact, our book may well be described as “Knightian.” What we appreciate in Knight is his emphasis on uncertainty rather than risk as characteristic of most business decisions and not just the major ones. Someone has to shoulder the uncertainty (it is uninsurable) associated with setting up an enterprise and because these ideas are often not fully or clearly articulable, the result is that entrepreneurs set up firms, bearing responsibility for any profits or losses the venture make. However, Knight’s ideas go much beyond start-ups.

Another source of inspiration is the Austrian school of economics. In the book we put much emphasis on resource heterogeneity and all the many problems of measuring, monitoring, combining, coordinating and so on that arise in a world of heterogeneity. All management problems are caused by such heterogeneity in conjunction with uncertainty. This is something mainstream economics still has to embrace.

Question: You make the point that “problem-solving activities in firms have many of the features of experimental activity“. This view radically contrasts with the typical microeconomics textbook view whereby firms face a simple optimization problem (maximizing profits subject to known constraints) ....

Foss: True. But economics simply has to accommodate the fact that the choice of production methods, the combination of resources, the sourcing of knowledge and so on are not “data”.Hayek was very explicit about this in a brilliant essay from 1948 (“The meaning of competition”). Firms may be groping towards optimum resource combinations, but they are really tracking a moving target, because of shocks to technology, tastes, policies, and so on. And to the extent that they succeed in tracking the target it is because of sound managerial judgment. I must say, though, that I see many of the younger applied microeconomists, such as Nick Bloom and John van Reenen, adopting this basic view. They need to make sense out of the managerial function.

Question: You have a very interesting chapter on internal organization and intrapreneurship (entrepreneurship within firms), where you disagree with the trendy claim in the tech start-up world “that authority and traditional firm organization are fading under the impact of delegation of decision rights to entrepreneurial employees who control critical knowledge.” Why?

Foss: Well, the “trendy claim”, as you call it, has some truth to it. There is evidence of increased delegation, particularly in fast moving industries, and it is also evident that there is a tendency to shift decision rights to employees that are high in human capital. Some of my empirical work with my CBS colleague Keld Laursen speaks to this issue. However, authority has efficiency advantages that just don’t disappear like that. First, authority economizes on the costs of transmitting knowledge: Rather than telling someone why he should carry out a task, how it fits into the big picture, and so on, the holder of authority simply tells someone to get it done. Second, bosses often have superior knowledge, in which case they should give direction. Third, there is a need for someone to operate and maintain reward systems.
For another approach that explains why this "trendy claim" may not be true for all firms see "Simple models of a human-capital based firm: a reference point approach". Journal of the Knowledge Economy, forthcoming.

Harold Kuhn 1925-2014

Alvin Roth tells us the sad news that Harold Kuhn, the Princeton University mathematician who advanced game theory approaches to economics, died of congestive heart failure on July 2. He was 88 years old.

I had a couple of email interactions with Kuhn over the history of game theory and he was always helpful in explaining whatever it was I didn't know or understand.

Most economics students will know him from the Kuhn-Tucker conditions that they will have grown to know and love! Tucker was Kuhn's PhD supervisor.

Art Carden and David Neomark on the minimum wage

A case of the seen and the unseen. At the EconLog blog Cardin argues that while the (seen) unemployment effects of small changes in the minimum wage may be small what is unseen is the adjustments that take place on other margins.
In yesterday's Wall Street Journal, David Neumark argued that even though "modest increases" in the minimum wage won't have large disemployment effects, the minimum wage is a poorly-targeted anti-poverty measure: "Minimum wages are ineffective at helping poor families because such a small share of the benefits flow to them."

The broader discussion doesn't appreciate the ways in which firms and workers can adjust to a higher minimum wage without people losing their jobs or even without reductions in the number of hours worked. People do not work for wages alone but for a combination of wages, benefits, workplace amenities, and job satisfaction. Forcing people to pay and accept higher wages means they can compensate on other margins. Maybe you don't get as much general workplace training now (and make no mistake: that is valuable). Maybe you have to pay for your uniform. Maybe you don't get the same employee discount you otherwise would have received. Maybe you don't have as much scheduling flexibility. And so on. I haven't seen a good argument for why we shouldn't think these adjustments are important or for why we are better as a society by forcing people to trade a more flexible schedule for higher wages.
It's worth remembering that jobs like any other commodity have multiple dimensions to them, and changes on one dimension can be traded off against changes on other dimensions. The sum total of all these changes may or may not make workers better-off.

The Neumark article makes a different point, that a higher minimum wage would do little to help poor and low-income families:
A higher minimum wage raises wages of low-wage workers, and even though most evidence points to job losses from higher minimum wages, the evidence doesn't point to widespread employment declines. Thus, consistent with a recent Congressional Budget Office report, many more low-wage workers will get a raise than will lose their jobs. But that argument is about low-wage workers, not low-income families. Minimum wages are ineffective at helping poor families because such a small share of the benefits flow to them.

One might think that low-wage workers and low-income families are the same. But data from the U.S. Census Bureau show that there is only a weak relationship between being a low-wage worker and being poor, for three reasons.

First, many low-wage workers are in higher-income families—workers who are not the primary breadwinners and often contribute a small share of their family's income. Second, some workers in poor families earn higher wages but don't work enough hours. And third, about half of poor families have no workers, in which case a higher minimum wage does no good. This is simple descriptive evidence and is not disputed by economists.
Neumark's basic point is that while the desire to help poor and low-income families is understandable increasing the minimum wage is a misguided way to do it. Other policies need to be looked at. In the US context Neumark suggests using the Earned Income Tax Credit (The United States federal earned income tax credit or earned income credit (EITC or EIC) is a sum deducted from the total amount a taxpayer owes to the state which applies to low to moderate income working individuals and couples—particularly those with children.),
The Earned Income Tax Credit directly targets low-income families, rather than low-wage workers. And my research with William Wascher, using Census Bureau data, shows that a higher EITC boosts incomes of poor families, and even—by encouraging work—leads to more low-income families earning their way out of poverty. The EITC could be made more generous, particularly for childless adults who currently get little from it.

Because the EITC operates through the tax code, it also has the virtue, in this era of rising inequality, of being financed disproportionately by those with the highest incomes. Raising the minimum wage is ineffective on that score because it is paid by those who hire low-wage labor. Some employers of low-wage labor may be rich, but many are not.
Such ideas could be applied to any tax system.

EconTalk for this week

Mike Munger of Duke University talks with EconTalk host Russ Roberts about the sharing economy--companies like Uber, AirBnB, FlightApp, and DogVacay that let people share their houses, cars, or other assets with strangers in exchange for money. These companies dramatically increase the use of resources that would otherwise be idle and disrupt existing services such as hotels and taxis. Topics discussed include the regulatory response to these companies, the politics of that response, and the significance of these new products. The conversation closes with the potential impact of Uber combining with driverless cars to change the automobile industry and cities.

EconTalk for many weeks

Steven Teles of Johns Hopkins University talks with EconTalk host Russ Roberts about kludgeocracy, a term Teles coined in a National Affairs article to describe what Teles sees as the complex and unproductive state of political governance in the United States, particularly at the federal level. Teles argues that various rules and procedures in the Senate and the House allow politicians to slow down legislation in return for favors. Teles argues that both liberals and conservatives have an incentive to favor more transparency and a more streamlined governing process that would get things done.

Megan McArdle of Bloomberg View and author of The Up Side of Down talks with EconTalk host Russ Roberts about her book. McArdle argues that failure is a crucial part of success in personal life and in the large economy. Topics covered include the psychology of failure, unemployment, and bankruptcy and parole.

Diane Coyle, author of GDP: A Brief but Affectionate History, talks with EconTalk host Russ Roberts about the history of GDP, its uses, and its abuses. Topics discussed include the origins of GDP in the developed countries, the challenges of measuring the service sector, the challenges of dealing with innovation and product diversity, whether GDP should be supplemented with other measures of human well-being, and the challenges of dealing with internet-based goods that produce a great deal of satisfaction but make a much smaller impact on measured economic activity.

Gregory Zuckerman of the Wall Street Journal and author of The Frackers: The Outrageous Inside Story of the New Billionaire Wildcatters, talks to EconTalk host Russ Roberts about his new book, the rise of hydraulic fracturing (fracking), how this technology developed, and the vibrant personalities that pioneered the energy revolution. Topics discussed along the way include the history and future of fracking, environmental concerns about the process, and how the story of fracking is the classic tale of the successes and failures of determined risk-takers. The role of market forces in driving that success and failure runs through the entire conversation.

Lars Peter Hansen of the University of Chicago and Nobel Laureate in economics, talks to EconTalk host Russ Roberts about the power and limits of economic models and quantitative methods. Hanson defends the value of models while recognizing their limitations. The two also discuss quantifying systemic financial risk, how our understanding of financial markets has changed, the nature of risk, and areas of economics that Hanson believes are ripe for further research.

Drug deals gone bad

Or are they?

Donal Curtin writes at the Economic New Zealand blog that
I was shocked - shocked! - to read in the Economist last week that drug companies, faced with the prospect of superprofits on patented drugs evaporating when the patents expire and the off-patent drugs can be substituted by much cheaper 'generics', have been paying generics producers not to enter the market.
Is this so bad? Looks like it could just be the Coase Theorem in action. Transaction costs are low for the companies involved and so they bargain to a mutually profitable outcome. Whats not to like?

Well maybe the problem is that not all affected parties are at the bargaining table. Under the Coase Theorem it is (implicitly) assumed that all parties affected by the externality, or whatever, are able to bargain with each other. In the drugs case clearly consumers are not at the bargaining table. Transaction costs prevent consumers of the drug, who would gain most from a price reduction, from bargaining with the companies involved, so their voice is not heard. The outcome therefore may not be the socially efficient one.

Smoking, plain packaging, and public health

A recent research report from the Adam Smith Institute reviews the evidence around plain packaging for cigarettes from Australia, the only country to have tried the policy so far. It finds that plain packaging has not had a noticeable impact on smoking rates, but has led to a significant rise in counterfeits, which are more easily available for underage smokers.

A more detailed summary of the paper's findings is.
In 2011, Australia’s government introduced legislation mandating that cigarettes be sold in “plain packages” (i.e., without brand logos and colours). The legislation came into effect in late 2012. (Australia had already banned practically all tobacco advertising and other forms of marketing. In 2006, it had introduced a requirement that cigarette packs display graphic health warnings on a substantial proportion of their surface area.)

Some studies (such as a survey carried out when plain packaging was being introduced, an analysis of calls to a smoking cessation hotline, and a survey of outdoor smoking habits) suggest that plain packaging has indeed, made cigarettes less desirable to smokers and has increased thoughts of quitting.

However, an online survey of smokers carried out in two phases, the first a month before and the second six to eight weeks after the introduction of the plain packaging rules, suggest that the impact of the rules on quitting tendencies is probably small. Moreover, many smokers engaged in defensive behaviors such as covering up health warnings, and did not report changing brands or a significant increased tendency to quit. This finding was corroborated by another survey that found that in the year to July 2013 the proportion of smokers in Australia had not declined since the introduction of plain packaging.

A study looking at discarded packs and other data suggests that consumption of cigarettes in the year to July 2013 remained at the same level as in 2012, but found that the proportion of illicit cigarettes had increased substantially. This is corroborated by the most recent Annual Report of Australia’s Customs and Border Protection Service, which indicates that the number of illicit cigarettes entering Australia has indeed risen dramatically in the past three years.

The discarded pack study concluded that contraband—much of which is in the form of finished cigarettes that are not legally sold anywhere in the world, known as “illicit whites”—now accounts for more than half of illegal sales and about 7.5% of all sales. Part of the blame for the increased availability of illicit whites lies with a 25% increase in excise tax on tobacco introduced in 2010. But, since most of the increase in their market share occurred in the past 18 months, part of the blame almost certainly rests with the plain packaging rules.

The wide availability of illicit whites in Australia means it is highly likely that adolescents now have greater access to cigarettes than previously—and at lower prices. Moreover, these “illicit whites” have no health warnings. Given the contribution of plain packaging in Australia to the rise of the illicit white, it seems reasonable to conclude that it has been counterproductive.
So another case of health advocates harts being in the rights place, but you have to wonder where their brains are?

Has the Great Recession harmed the long-term growth prospects of the Eurozone economy?

In this audio from VoxEU.org Philippe Weil is interviewed by Viv Davies and they discuss the above question. The CEPR Business Cycle Dating Committee recently concluded that there is not yet enough evidence to call a business cycle trough in the Eurozone. Instead, the committee has announced a 'prolonged pause' in the recession. This Vox Talk discusses the possible directions that this situation could lead to and questions whether the Great Recession has harmed the Eurozone’s long-term growth prospects to the extent that meagre growth could become the 'new normal'.
