Working Papers

The paper presents a newly compiled and improved database of national household surveys between 1988 and 2008. In 2008, the global Gini index is around 70.5 percent having declined by approximately 2 Gini points over this twenty year period. When it is adjusted for the likely under-reporting of top incomes in surveys by using the gap between national accounts consumption and survey means in combination with a Pareto-type imputation of the upper tail, the estimate is a much higher global Gini of almost 76 percent.

The global financial crisis led to widespread dislocation. Understanding the forces that led to such a crisis is no easy matter.

Ten hypotheses presented in the session “Beyond Deficits, Austerity and Deflation” at INET Conference 201

Recent weeks have surfaced an intense exchange of top-level finger pointing, both between Congress and the leadership of the Federal Reserve System, between Fed officials and executives in the private sector and within the Fed between the Board of Governors and the New York Reserve Bank.

It is impossible to ignore material inequality. Wealth, and the goods that come with it, are accumulating at the top of society while others seem to be struggling in the middle and bottom.

The inequality of income and wealth is one of the defining issues of our time, in terms of both its social and macroeconomic implications. In this article, I focus on the macroeconomic implications of inequality. In particular, it is possible to identify four themes on which there seems to be growing consensus among many economists especially in the various heterodox traditions, but also increasingly in the mainstream of the economics profession:

A Ruskinian framework for economic justice.

This paper discusses the main issues about increasing inequality, whether it matters and its impact on economic activity and growth. It starts by briefly considering the empirical evidence of the share of income going to the top one percent since 1945 in the advanced countries. It then considers whether this represents an increase in the productivity of the top one percent or merely an extraction of economic rent.

This text is part of a research project still in working progress that collects different contributions by the author and rewrite and reanalyse some reflections, already present, in a different form, in some publications:

It is highly fitting to have a panel devoted to ‘teaching economics’ in Paris. No less than 15 years ago, in 2000, in downtown Paris, a group of students from the École Normale Supérieure, one of France’s élite schools, wrote a petition asking economics teaching to be devoted to the study of real-world problems, with an instrumental use of mathematics rather than to the description of imaginary worlds based on meaningless formalizations.

The financial crisis of 2008, and the subsequent worldwide economic depression and continuing dislocation, have made little to no impression on the way macroeconomics is taught at the university level, from Economics 101 through graduate school. It has been “business as usual’, which (it seems to me) means an almost studious avoidance of any attempt to acquire knowledge of how monetary economies actually work.

How to rebalance Chinese economy has become a topic of heated discussion. After years of fast economic expansion, now China faces a difficult crossroad. The global financial crisis provided clear evidence that China’s traditional export-driven strategy is vulnerable to slumps of the external demand.

When the Curriculum Open-access Resources in Economics (CORE) project launched on 11 November 2013 at Her Majesty’s Treasury in London, we promised that we would be ‘teaching economics as if the last three decades had happened’. The last six months have shown us that this is challenging but we are well on our way to doing it.

Economics has advanced an enormous distance from the Walrasian paradigm and the Neoclassical synthesis. However, undergraduate curriculums continue to heavily favour these views of what economics is and what tools it provides for understanding contemporarypublic problems.

The president of INET, Johnson(2013) emphasized the importance of Asian tradition for building up the New Economic Thinking. “It ismy sense that the Asian tradition of thought and philosophical perspective are better suited to embracing this radical uncertainty and living in the experimentation of the adaptive complex system that our world appears to resemble than are the Western mindsets that are the product of the Cartesian Enlightenment.” In the summary he argues that “As the Asian societies continue to evolve the architects will be better served by an new economics for Asia and from Asia that is based on the notions of radical uncertainty, complex adaptive systems, mimetic desire, the inseparability of politics and economics, and a vision of a world where policy makers are themselves less knowing and less capable of control than we often yearn to believe is within their power.”

The Arab Spring has been a fundamental event in the Arab world and yet among Middle East scholars, there is great intellectual and analytical debate about the degree of political change or continuity that the Arab Spring had produced. As reverberations of the global economic crisis have continued and the international rules of the game have fundamentally remained unchanged, the demand on post-Arab Spring governments to change policy course is high.

In the United States achieving equal opportunity in postsecondary education is typically described in terms of enrolling more underrepresented groups into the selective colleges. The belief is that if this step is accomplished it will have a fundamental impact on the problem of inequality at the national level. However, what if there are not enough places in selective colleges to accomplish this goal? What if the selective colleges do not have enough capacity to make a significant impact in the problem of serving students from underrepresented groups withdemonstrated high abilities?

The chief obstacle to transformative change in the contemporary Middle East is the region-wide configuration of social power which was consolidated in the Arab provinces of the Ottoman Empire and which survived the transition from empire to post-Ottoman independent states largely intact.

The term human capital describes a set of skills, strengths and know-how that are valuable—both in the narrow sense of being “commercially valuable” (Lindsey, 2013), and the wider one of contributing to a flourishing, deliberate, purposeful life.As Heckman (2014) puts it: “Skills are capacities to act [emphasis added]…They shapeexpectations, constraints, and information” (p. 6).

While successive waves of democratization over the last half century changed the political landscape in various regions of the world, the authoritarian regimes have maintained their hold on power in the Arab region.

Debate about the pension crises has centered on certain questions such as: Are greedy government workers bankrupting states? Arepension-slashing politicians backed by big money saving the day? Or do the budget problems of state and localgovernments have more to do with wasteful corporate subsidies than pensions? What are the real policy solutions to the pressures placed on pensions?”

Economists discussing the problem of radical uncertainty commonly invoke Frank Knight’s classic definition in Risk, Uncertainty and Profit, but only rarely venture to explore the broader contours of his argument.

Cyberwar is very much in the news these days. It is tempting to try to understand the economics of such an activity, if only qualitatively. What effort is required? What can such attacks accomplish? What does this say, if anything,about the likelihood of cyberwar?

Five years after the end of the Great Recession, corporate profits are high and the stock market is booming. Yet most Americans are not sharing in the apparent prosperity.

This article studies the reasons for the under-investment in research vs. development in the decentralized equilibrium and argues that this bias provides a micro-foundation for the government direct involvement in conducting applied research rather than just financing it.

The fall of 2008 was scary. For most people, the aftermath of Lehman Brothers’ bankruptcy resembled a major earthquake with strong aftershocks. Official narratives have promoted the image of the crisis as a rare, unpreventable and unforeseen natural disaster, the “100-year flood.” Policymakers emphasize the extraordinary measures they have taken to prevent the system from collapsing and to support recovery since.

Innovation, the commercialization of invention, is both desirable and necessary for growth and higher living standards in modern economies. Innovation’s contribution to the economy is being measured increasingly more precisely, and its contribution has been assessed aseconomically important and growing.

Since the outbreak of the Greek debt crisis at the end of 2009, the Eurozone finds itself in an unprecedented debt crisis.

We analyse the link between income distribution and the current account for the period 1972-2007. We find that rising (top-end) personal inequality leads to a decrease of the current account, ceteris paribus.

Can China lead the way on innovation?

A genome-wide association study (GWAS) of educational attainment was conducted in a discovery sample of 101,069 individuals and a replication sample of 25,490. Three independent single-nucleotide polymorphisms (SNPs) are genome-wide significant (rs9320913, rs11584700, rs4851266), and all three replicate.

These are extraordinary times for central banks. Near zero interest rates and massive liquidity injections are still failing to bring life back to so many economies in the developed world.

In this paper we provide a summary and a guide to the literature for a new line of research which goes under the name of Economic Complexity and is partly performed incollaboration with INET.

“Look! Up there in the sky! What is it? Is it a plane? Is it a bird?” No, it’s a distraction from the robbery that is taking place in broad daylight on the ground.

Innovation. The word is evocative of ideas, products and processes which have somehow made the world a better place. Prior to the global financial crisis, many viewed financial innovation as unequivocally falling into this category.

The exteriors of major central banks may be solid marble and doric columns, but, inside, monetary policy remains a work in progress.

Only a few years ago, comparisons of American politics to opéra bouffe were not outrageously farfetched at least if you were not poor or sick.

Since the dawn of this millennium, and long before the current financial turmoil and the subsequent bitter pill of austerity therapy hit the Untied States and the European Union, the Chinese Communist Government has publicly recognized the monumental challenge of polarity.

There are a number of possible purposes in assessing the level of economic development of a country or part of a country. The assessment may provide an incentive for better development, particularly if it can be compared meaningfully with assessments for other countries.

“Taking advantage of the opportunity offered by the structural adjustments of the global economy…”The decisions on the four modernisations taken at the Third Plenum represented a radical change in Chinese domesticdevelopment strategy.

Political meritocracy is the idea that a political system is designed with the aim of selecting political leaders with above average ability to make morally informed political judgments. That is, political meritocracy has two key components: (1) the political leaders have above average ability and virtue and (2) the selection mechanism is designed to choose such leaders.

At the heart of economics is a theory of action. It reflects views about how human beings make economic decisions and leads to an analysis of aggregate consequences.

A core puzzle in Önancial economics is the inability of standard risk-premium models to account for excess returns in currency and other asset markets.

Neoclassical economics has abolished the role of psychology in decision making by assuming that all individuals are rational optimizers with rational expectations about future events.

The global financial crisis led to the rediscovery of ‘fundamental uncertainty’. Incorporating uncertainty into the analysis of financial markets alters our understanding of how these markets operate and expose the two-faced role of law in finance.

There is much anecdotal evidence in the popular media, backed up by survey research, that participants in currency markets pay close attention to fundamental economic variables in forming their forecasts of future exchange rates.

For macroeconomists, an individual is rational if she uses her understanding of the way the economy works in making decisions that do not conflict with her objectives.

The present-value model of stock prices is a workhorse in financial economics. The model relates today’s price of a stock (or a basket of stocks) to the market’s forecasts of next-period’s price and dividend, appropriately discounted.

In this paper, we examine one of the core puzzles in International Macroeconomics, the so-called “forward-discount anomaly.”

A core premise of contemporary economic models is that researchers can adequately specify in probabilistic terms how individuals alter the way they make decisions and how the processes underpinning market outcomes unfold over time.

The first part of this text comes back on the standard economic viewpoint on expectational coordination, a viewpoint that the recent events have challenged.

State and market are often depicted as distinct, even antagonistic. Markets appear as natural products of spontaneous ordering; states as leviathans that if left untamed will distort, if not destroy markets’ natural state.

Uncertainty is an unavoidable feature of economic life, although we may cope with it sometimes by ignoring it. Institutions, conventions and behaviour are all conditioned by uncertainty, and they in turn condition uncertainty in a reflexive manner.

The reason why the Euro zone crisis has dragged on for so long is that Europe’s leaders have focused too much on short-term measures to patch up the emergency of the moment, rather than formulating a comprehensive plan.

After the announcement of Mario Draghi, the ECB president, to do “whatever it takes” to preserve the integrity of the European Monetary Union (EMU) in July 2012 and the establishment of the Outright Monetary Transactions (OMT) program in September 2012, the crisis of EMU is far from being resolved.

Mercantilism, Accumulation of Foreign Exchange Reserves, and RMB Internationalization

Regulation and supervision of banks and financial markets are now upgraded in the euro area. Surveillance of macroeconomic performance of all EU countries is also intensified.

In the first ten chapters of our book, The Bankers’ New Clothes: What’s Wrong with Banking and What to Do about It, we discuss banking and the economics of funding as it applies to banks.

Europe can choose its musical accompaniment. In Berlin, 50 Cent’s All Things Fall Apart has just had its premiere. Or go back to Giuseppe Verdi, born two hundred years ago.

Internationalization of the renminbi is a stated goal of the Chinese government, its brief flirtation with Special Drawing Rights and an Asian Currency Unit notwithstanding. Chinese officials understand that a dollar-centric international monetary and financial system is a mixedblessing.

Healthy innovation economies are the main driver of prosperity in the 21st century. But the three players that have traditionally sponsored basic research and invention in those economies are no longer willing or able to perform that role.

In “The Ambivalence of Scarcity” which is my contribution to L’Enfer des choses. René Girard et la logique de l’économie, written by Jean-Pierre Dupuy and originally published in French in 1978, I attempt to apply mimetic theory to modern economics and to economicphenomena, and also to explain why economic issues and economics as a discipline occupy such an important place in the modern world.

My remarks today will be focused primarily on features of the developed world’s financial system which led to the crisis of 2008 and to the Great Recession that followed, from which we are only slowly and painfully emerging.

In his recent lecture at the Cass Business School, Lord Turner noted that even mentioning the possibility of overt monetary financing was akin to breaking a taboo.

A striking feature of the neoclassical economic theory which has been dominant in Western universities in recent years is that it has had so little to say about innovation and innovation policy which is useful for policy-makers.

It would be nonsensical to blame economists for not foreseeing the crisis; even less for causing it. It was obvious there would be a crisis. It was impossible to foresee how it would start and evolve, and at what moment these events would occur.

The problem of value has always occupied a central place in economic thought and debate.

The ongoing eurozone crisis has prompted many to argue that monetary union withoutfiscal union was bound to fail.

Albeit the majority of the profession either ignores Minskyís Financial Instability Hypothesis (FIH) or considers it plainly wrong, at least since the mid-80’s a few influential economists —who have certainly not embraced any unorthodoxcredo —have grown more receptive to this idea and eager to incorporate it in their models, even if diluted and sometimes disguised in order to make it more palatable to the conventional “representative” macroeconomist

I am supposed to speak about Complexity Economics and the issues this theoretical approach is able to illuminate. Defined as such, it appears as if I should discuss methodology and I am reminded of Paul Krugman’s quote: “It is said that those who can, do, while those who cannot, discuss methodology”. So, having a discussion centered on methodology may give the impression that the panelists in this session are unable to make scientific progress.

Elephant seals have got too big for their beaches. A large specimen might weigh over 8000 lbs (3700 kg).Their size has a simple evolutionary explanation. Large males fight for the right to mate with a whole beach full of females. For elephant seals it is, quite literally, winner-takes-all. And the key to winning is simple – size.

We have grown accustomed to regulating financial markets based on imagined, not real markets. Real markets are shaped by and co-evolve with institutional arrangements within two fundamental constraints: Imperfect knowledge and the threat of illiquidity.

The financial sector can support growth but it can also cause crisis. The present crisis has exposedgaps in economists’ understanding of this dual potential.

In the seemingly never-ending aftermath to the economic crisis that began in 2007, there is little disagreement that financial markets are characterized by instability rather than stability.

Taking a long‐run view from economic history, I make three points about instability in financial markets. First, I argue that economic historians have a relatively good understanding of the proximate causes of financial crises.

“Natural rate theory” has dominated interpretations of economic trends and policy prescriptions over many decades. European-type welfare state institution were claimed to cause a compressed wage distribution that distorts otherwise well functioning labor markets.

Many models of economic growth exclude materials from the production function. Growing environmental pressures and resource prices suggest that this may be increasingly inappropriate.

The topic of this session of the INET conference is a question: does the effectiveness of fiscal policy in stabilizing an economy depend on the underlying economic context in which the policy is implemented?

The present paradox, as ecological economist Bill Rees is fond of putting it, is simple yet profoundly troubling: “The ecologically necessary is politically infeasible, but the politically feasible is ecologically irrelevant.”

Three major crises are confronting the world. The first is the increasing and uneven burden of humans on the biosphere, and the observation that we have already surpassed the ‘safe operating space’ for humanity with respect to three planetary boundaries: climate change, the nitrogen cycle and biodiversity loss.

The path to better understanding the economy requires treating the economy as the complex system that it really is. We need more realistic behavioral models, but even more important, we need to capture the most important components of the economy and their most important interactions, and make realistic models of institutions.

In 1803 Louis Poinsot, a French physicist, wrote a book of great success, Elements de Statique, which was destined to have practical and social influences unimaginable to the same author.

In the last few years the impact of income distribution on macroeconomic dynamics has received growing academic attention.

Long periods of unequal incomes spur borrowing from the rich, increasing the risk of major economic crises

Higher income inequality in developed countries is associated with higher domestic and foreign indebtedness

We analyze shareholders’ incentives to change the leverage of a firm that has already borrowed substantially. As a result of debt overhang, shareholders have incentives to resist reductions in leverage that make the remaining debt safer.

Budget cuts can be dangerous. Inspired by the wrenching experience in Greece, increasing attention is now being paid to the fact that austerity may fail to reduce the government deficit if the economy declines in response, as is likely in a liquidity trap (Delong and Summers 2012).

These are truly testing times. The world economic order – capitalism – is being called into question following the Lehman crisis. The world’s best form of societal organization – democracy – is being challenged by the economic success of autocratic countries such as China and Singapore.

In modern economies, individuals and companies engage in innovative activities, discovering new ways to use existing physical and human capital, and new technologies in which to invest. The institutional and broader social context within which these activities take place also changes in novel ways.

With my remarks today on financial markets and the financial crisis, I do not make any claims to originality. Rather, they are intended as a reminder of certain circumstances that are already familiar to us, in one form or another.

In a classic book and subsequent articles, Obstfeld and Taylor (2004) have shown how the broad contours of international financial history over the past century and a half can be well understood by appealing to the famous economictrilemma which emerges from the standard Mundell-Fleming model many of us still teach our undergraduates.

The euro area’s sovereign debt crisis continues though significant steps have been taken to resolve it.

In preparing this paper I have decided not to embark upon the decades-old issue of optimal-currency areas and governance as such. I assume that one of my colleagues on the panel will do that. Instead I will present an historical case of over-indebtedness of parts of a common-currency area somewhat similar to the present challenge of Europe, or rather of the Euro area with its common currency.

Investment in productive capabilities provides the foundation for economic growth.

Our shared concern – 20 years after Rio, yet poor progress towards wellbeing

Globalization has improved the living standards of hundreds of millions of people – but growing resource scarcity means it risks becoming a victim of its own success.

Government intervention is often perceived as a constraint on market forces and thereby on economic growth.

All cultural narratives, worldviews, religious doctrines, political ideologies, and academic paradigms are ‘social constructs.’
