Working Papers

In recent decades, advanced economies have experienced low and stable inflation and long periods of liquidity trap. We construct an alternative business-cycle model capturing these two features by adding two assumptions to a money-in-the-utility-function model: the labor market is subject to matching frictions, and real wealth enters the utility function. These assumptions modify the two core equations of the standard New Keynesian model

John Muth proposed the Rational Expectations Hypothesis (REH) to represent how the market (an aggregate of its participants) understands and forecasts outcomes. REH imposes internal consistency between the market’s forecasts and “the relevant economic theory” (Muth 1961, p. 316).

I first came across economics students’ campaigns to revolutionise their education in that bastion of radical thought: the newsroom of the Financial Times.

Among the areas left largely unscathed by the 2008 financial crisis and subsequent never-­‐ending recession, the teaching of economics ranks high.

This paper proposes a different interpretation of the Eurozone crisis, seeing as its “final” cause European policies which have forced private savings down too low.

Hubris might well head the list

In much of Europe, the social rights and social protections won in the first post-war decades, by labour movements in particular, have subsequently been seriously eroded, and are further threatened by neoliberal austerity.

This memo outlines key concepts and the methodological approach involved in a recently funded Institute for New Economic Thinking project. Our aim is to pinpoint the relationship between the reception of academic ideas, traced by citation networks with qualitative coding, and positions of institutional and political power.

We discuss recent work on bounded rationality and learning in relation to Soros’ principle of reflexivity and stress the empirical importance of non-rational, almost self-fulfilling equilibria in positive feedback systems.

Considerable academic and public attention has been drawn to the pulling away of the very rich—the so-called “one percent” whose gains have far outpaced those of everyone else (Piketty 2014). But the debate has reached well beyond the very top, especially in the United States.Indeed, the hollowing out of the middle class, continuing stagnation of wages, and new evidence on the lack of upward mobility across generations all strike at the very heart of the American ideal.

Italy was one of the worst hit during the 2007–2009 global financial crisis (GFC) among the major advanced economies. By year-end 2009, Italy’s economy had contracted by 6.6 percent; significantly larger than the recessions in the euro zone and the United States, for example, which saw their GDPs shrink by 4.4 and 3.1 percent, respectively.

In the past three years, students around the world have turned the heat of scrutiny onto our economics departments. Our call is strikingly uniform across our diverse cultures and languages: we want critical debate back in the economics curriculum.

“Because many interests come into play in the financing of an election campaign and then they ask you to pay back. So the election campaign should be independent from anyone who may finance it.” - Pope Francis

Pushing this strand of research brings a certain feeling of trepidation. It comes from recognizing that by openly elaborating on how to catch or deter a criminal, you thereby confer an undue advantage on the criminal through forewarning.

Initiatives to improve sovereign debt restructuring (“SDR”) began long before recent Argentine bond decisions but were redoubled in the aftermath of these rulings. At first glance, these cases identify problematic contract language that could be rectified by re-drafting critical boilerplate provisions such as the pari passu and collective action clauses (“CAC”).

The Cyclically Adjusted Budget (CAB) is the estimated size of the public budget at some previously defined level of output which may represent the ‘normal’ output or a policy target and that usually is considered to be unaffected by business fluctuations or cycles. Such an estimate is supposed to isolate the automatic movements of revenues and expenditures, given the current structure of tax and transfers, from discretionary fiscal interventions and indicate the “impact” and sustainability of fiscal action.

Inequality has emerged as a major economic issue: sharp increases in the share of income going to those at the very top of the income distribution, a rising share of income going to profits, stagnant real wages, and a fall in median family income have raised concern over the sustainability of our economies and societies.

Over the past decades African economies have exhibited two stunning paradoxes: growth acceleration coexisting with stubbornly high poverty rates; increasing capital flight along with widening development financing gaps. There has been no attempt to link the two in the literature.

The modern individual is the point of intersection of the processes of consumption and production. The subjective representation of these processes has been determined by two branches of the modern middle class, the bourgeoisie, which has privileged consumption, and the bureaucracy, which has privileged production.

This paper will address the problem of how we might gain economic understanding from literature. It will look at the aesthetic form of literature as being an efficient vehicle for economic thinking.

The largely unexpected arrival of the global economic crisis and the largely unpredicted slowness of the recovery from the Great Recession should be precipitating an intellectual crisis across economics and policy making. We require additional theories and additional methods to detect how an economy is evolving and to provide the basis for policy intervention (Haldane, 2014).

During the past year, there have been numerous and somber reflections, rather like those during a traditional period of mourning, about the great and tragic events that occurred just 100 years ago – the beginning of the First World War. And in the course of these melancholy reflections about the past, there naturally have arisen anxious concerns about the future.

What is at stake : Increasing doubt over the virtue of democracy. One cannot doubt the ubiquitous lack of confidence and hope in the so-called democratic institutions by a large majority of the people. The fundamental cause is the blatant contradiction between the principle of democracy, promoting the rule and thereby the welfare of the people, and the indomitable tendency of rising and unsustainable inequality in terms of income, standard of living and wealth.

The central concepts of Keynes’ macroeconomic theories concerning the behavior of labor markets, aggregate demand, and asset pricing can be formulated as special cases of a general social interaction model.

In this paper, we deal with the complex relationship connecting inequality to innovation, and the ways through which public investment, in particular public participation to R&D initiatives, may affect it. We first stress that multiple different equilibria may exist in the inequality-innovation space.

This paper studies the glass ceiling by analyzing the presence of women at the top of the income distribution using tax record data reported for a sample of countries with individual taxation.

Using a sample of U.S. firms spanning 2001-2011, we examine whether female directors (female audit committee members) affect audit quality in terms of audit effort and auditor choice.

This paper presents a theory of pseudo-wealth in a model that displays aggregate demand externalities.

A recent New York Times article observed that Americans want action to address inequality. 2016 presidential candidates from both parties also acknowledge that inequality is a pressing concern. But not one of the candidates has proposed to do anything meaningful about it, sharing wealthy Americans’ (understandable) opposition to any solution (Scheiber 2015). Perhaps nothing has been done because there is nothing to do about it.

A structural transformation is investing labour in Europe, accelerated by the crisis started in 2008. Job destruction is dominating employment trends in most EU countries and deep changes are taking place in labour relations, labour market institutions and wage regimes.

We develop a novel stress-test framework to monitor systemic risk in financial systems. The modular structure of the framework allows to accommodate for a variety of shock scenarios, methods to estimate interbank exposures and mechanisms of distress propagation.

Innovation is essential to economic growth. However, it appears that the ways in which we pursue innovation policies have aggravated inequality. Inequality is an increasingly contentious political issue in both wealthy and emerging economies.

“Oh, the Chinese hate the Japanese and the Japanese hate the Chinese—to hate all but the right folks is an old established rule. The Koreans hate the Japanese and the Vietnamese hate the Chinese, and the North Koreans hate them all. Oh, the People hate the Communists and the Communists hate the People. The Nationalists hate the Communists and the Communists hate themselves. The Confucians hate the Buddhists and the Muslims hate them all. All of my folks hate all of your folks. But during National Brotherhood Week, be nice to people who are inferior to you. It’s only for a week, so have no fear—be grateful that it doesn’t last all year.”

This paper finds its origins in two important developments within mainstream economics since the financial crisis, both of which analyze the economy from the viewpoint of what Schumpeter (1954) referred to as the domain of “real” analysis of a modern market economy in contrast to “monetary” analysis.

Caring Economics is about a new way of thinking about human prosperity. In mainstream economics, prosperity is a matter of consumption, income and wealth. By contrast, Caring Economics conceives of prosperity in terms of deeper sources of durable human wellbeing.

The SSGAC is a research infrastructure designed to stimulate dialogue and cooperation between medical researchers and social scientists. The SSGAC facilitates collaborative research that seeks to identify associations between specific genetic markers (segments of DNA) and behavioral traits, such as preferences, personality and social-science outcomes.

Behavior genetics is the study of the relationship between genetic variation and psychological traits. Turkheimer (2000) proposed “Three Laws of Behavior Genetics” based on empirical regularities observed in studies of twins and other kinships. On the basis of molecular studies that have measured DNA variation directly, we propose a Fourth Law of Behavior Genetics: “A typical human behavioral trait is associated with very many genetic variants, each of which accounts for a very small percentage of the behavioral variability.”

Income and wealth inequality have been rising in the past three decades. Surprisingly, inequality has been largely ignored in the literature and practice of monetary policy. However, due to the crisis, this question has been gaining more attention.

Recent years have witnessed the flourishing of a body of economic literature concerned with the search for empirical evidence of a positive relation between political connections, economic rent and the value of firms. The present paper contributes to the strand of this literature that deals with the quantitative measurement of the value of the political connections of firms.

Regulation of financial services has been an unmitigated policy disaster.

This essay argues that the Achilles heel of the international monetary and financial system is that it amplifies the “excess financial elasticity” of domestic policy regimes, ie it exacerbates their inability to prevent the build-up of financial imbalances, or outsize financial cycles, that lead to serious financial crises and macroeconomic dislocations.

The logic of deep global capitalist crises needs to be incorporated centrally into an understanding of the changes in the within-country inequality levels. I present a theoretical framework that incorporates two levels of political economic processes. First,global capitalist crises lead to the creation of an institutional structure or a regime in the capitalist centers that influences inequality in these core countries and in the periphery. Second the class configuration in the non-core countries - a set of institutional arrangements that can be termed local political economy - also plays a key role in determining inequality outcomes.

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:

This paper empirically examines the effects of the Federal Reserve’s Large Scale Asset Purchases (LSAP) on bank profits.

Do large firm dynamics drive the business cycle? We answer this question by developing a quantitative theory of aggregate fluctuations caused by firm-level disturbances alone. We show that a standard heterogeneous firm dynamics setup already contains in it a theory of the business cycle, without appealing to aggregate shocks.

We call attention to the class of models that serve as the foundation for the rational expectations hypothesis (REH). Models in this class rule out completely any structural change that cannot be fully anticipated with a probabilistic or other quantitative rule. REH models are abstractions of rational decision-making, but only in a hypothetical world in which participants can fully anticipate when and how they might revise their understanding of the process driving outcomes.

A Ruskinian framework for economic justice.

We propose several multivariate variance ratio statistics. We derive the asymptotic distribution of the statistics and scalar functions thereof under the null hypothesis that returns are unpredictable after a constant mean adjustment (i.e., under the weak form Efficient Market Hypothesis). We do not impose the no leverage assumption of Lo and MacKinlay (1988) but our asymptotic standard errors are relatively simple and in particular do not require the selection of a bandwidth parameter. We extend the framework to allow for a time varying risk premium through common systematic factors.

We develop adjustments to align the NIPA measures of key household flows with cash flow concepts that better reflect household budgets and demand.

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 chapter surveys experimental research on networks in economics.

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 interaction between social structure and markets remains a central theme in the social sciences. In some instances, markets can build on and enhance social networks’ economic role; in other contexts, markets appear to be in direct competition with social networks. The impact of markets on inequality and welfare is also varying: while markets can sometimes offer valuable outside options to marginalised individuals, in other situations only well connected and better off individuals can benefit from them.

When the adoption of a new labor‐saving technology increases labor productivity, it is an open question whether the economy adjusts in the medium‐term by decreasing employment or increasing output. This paper studies the effects of cheaper electricity on the labor market during the Great Depression.

Individuals derive benefits from their connections, but these may, at the same time, transmit external threats. Individuals therefore invest in security to protect themselves. However, the incentives to invest in security depend on their network exposures. We study the problem of designing a network that provides the right individual incentives.

It is instructive to view the study of networks in economics as a shift in paradigm, in the sense of Kuhn (1962). This perspective helps us locate the innovation that networks bring to economics, appreciate different strands of the research, assess the current state of the subject and identify the challenges.

Shiller (1981) and others have shown that the quantitative predictions of the REH present-value model are inconsistent with time-series data on stock prices and dividends. In this paper, we assess the empirical relevance of the model without explicitly representing how a rational market participant forecasts dividends and interest rates.

The ongoing explosion of the incomes of the richest households and the erosion of middle-class employment opportunities for most of the rest have become integrally related in the now-normal operation of the U.S. economy.

Recent work has highlighted the need for innovation investments to be understood through a mission oriented approach rather than a market failure one (Foray et al. 2012). However, this work has only focused on state agencies, such as DARPA, overlooking the role of public financial institutions such as state investment banks.

The tension between efficiency and equilibrium is a central feature of economic systems. In many contexts, social networks mediate this trade-off: an individual’s network position determines equilibrium play, and social relations allow coordination on an efficient norm.

The economics of religion is a relatively new field of research in economics. This survey serves two purposes – it is backward-looking in that it traces the historical and sociological origins of this field, and it is forward-looking in that it examines the insights and research themes that are offered by economists to investigate religion globally in the modern world.

This paper examines the effects of intra-financial lending – claims between financial institutions – on aggregate investment and credit to the non-financial sector in the United States.

There is widespread and growing concern about the availability of good jobs in the U.S. economy. Inequality has been growing for thirty years and is now at levels not seen since the 1920s. Stable and remunerative employment has become harder for U.S. workers to find.

This paper examines the evolution of intra-financial sector lending in the United States, 1950- 2012, presenting estimates constructed from the Federal Reserve’s Flow of Funds Accounts.

Rising inequality reduced income growth for the bottom 95 percent of the US personal income distribution beginning about 1980.

Anyone who has spent time in a developing country knows the importance of social connections. Among their many roles, these connections help individuals land jobs, and provide them with credit and other forms of support.

The flummery of capital-requirement repairs undertaken in response to the Great Financial Crisis.

As the financial economy has expanded beginning in the mid-1980s, it has done so in part by selling more products to individuals and households.

We analyze the political environment in the wake of financial crises and try to infer its implications on decision making and economic policies.

We show how every stock-flow consistent model of the macroeconomy can be represented as a directed acyclic graph.

In the past decade and a half, state and local public employee retirement systems in the United States have significantly shifted their fund investment strategies toward a greater allocation in alternative investments. Today, roughly $660 billion of public pension funds are invested in hedge funds and private equity funds. These alternative investments typically require new governance structures within the pension funds in order to adequately monitor accompanying risks and returns, management fee arrangements and investment complexity.

Why do so many people who should know better argue that Neoliberalism ‘does not exist’?

The 2007-2009 financial crisis initially appeared to have destroyed a huge amount of wealth in the U.S.

Inspired by the Coasean “market vs firm” dichotomy, we offer a new definition of efficiency by applying the notions of network cost and network efficiency as developed in complex network theory.

It is impossible to tell the history of American antitrust law and economics during the so-called formative era (1890- 1915) without a preliminary understanding of the economic rationale underlying that major phase of American constitutional law commonly called laissez faire constitutionalism, or Lochner era.

A nation must accumulate a high-tech knowledge base to prosper.

Thomas Piketty vs. Luigi Pasinetti and John Maynard Keynes

This paper is based on a social accounting matrix (SAM) which incorporates the size distribution of income based on data from the BEA national accounts, the widely discussed 2012 CBO distribution study, and BLS consumer surveys.

Using data on industrial air pollution exposure in the United States, we compute three measures of environmental inequality: the Gini coefficient of exposure, the ratio of median exposure of minorities to that of non-Hispanic whites, and the ratio of median exposure of poor households to that of nonpoor households.

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.
