We make the case for investigating the gap between the potential and the actual level of production, and review contributions that point to the reduced power of standard policy in- struments in presence of a prolonged gap. We also highlight di¢ culties in measuring where an economy stands relative to its potential. We review links between human capital accumulation and technology, and sketch a basic Schumpeterian model that puts at the center stage of the growth process investments in innovation and the foundation of new Örms, arguably two key sources of growth that could revitalize the faltering European Economies. The gap between the short and long run behavior is illustrated through quantitative experiments.

We review some of the literature at the intersection of innovation, financial markets, and economic growth. We explore two key questions: (i) How financial markets interact with innovation; (ii) what type of quality transformations are brought about by innovation. A special emphasis is given to questions that stem from the 2008 economic and financial crisis, and to subjects further developed in the articles collected in this issue.

The Kiyotakiand Wright model has exerted a considerable influence on the monetary search literature. We argue that the model also delivers important insights into abroader range of macroeconomic and development issues. The analysis studies howmarket frictions and the liquidity of assets affect the distribution of income. Experimentsillustrate how the economy adjusts to shocks to asset returns and to the matchingtechnology. They also deal with long-run transition. An experiment interprets thereversal of fortune hypothesis as a situation in which an economy with a low-returnasset takes over a similar economy with a high-return asset

An algorithm for computing Dynamic Nash Equilibria (DNE) in an extended version of Kiyotaki and Wright (1989) (hereafter KW) is proposed. The algorithm computes the equilibrium pro.le of (pure) strategies and the evolution of the distribution of three types of assets across three types of individuals. It has two features that together make it applicable in a wide range of macroeconomic experiments: (i) it works for any feasible initial distribution of assets; (ii) it allows for multiple switches of trading strategies along the transitional dynamics. The algorithm is used to study the relationship between liquidity, production, and inequality in income and in welfare, in economies where assets fetch different returns and agents have heterogeneous skills and preferences. One experiment shows a case of reversal of fortune. An economy endowed with a low-return asset takes over a similar economy endowed with a high-return asset because, in the former economy, a group of agents abandon a rent-seeking trading behavior and increase their income by trading and producing more intensively. A second experiment shows that a reduction of market frictions leads both to higher income and lower inequality. Other experiments evaluate the propagation mechanism of shocks that hit the assets.returns. A key result is that trade and liquidity tend to squeeze income inequality.

The paper reviews the state of the economic literature on the link between financial development and growth. We first examine the issue of measurement of financial development and the debate on the direction of causality between finance and growth. Next, we extensively discuss the various channels through which the financial sector can affect growth, including the increase in the efficiency of capital allocation, the reduction in information costs, the improvement of risk management, and the support of innovation. The analysis is conducted referring both to the theoretical literature and to the most recent empirical findings. We conclude by drawing lessons for the current debate on the reform of the financial sector in the aftermath of the Great Recession.

Le gouvernement, fort de la loi visant à reconquérir l’économie réelle, dite loi Florange, qui institue la possibilité de votes doubles pour les actionnaires patients (conservant leurs actions au moins deux ans), vient de prendre deux décisions significatives en augmentant temporairement sa participation au capital de Renault et d’Air France afin d’éviter qu’en assemblée générale cette possibilité de votes doubles soit rejetée par la majorité qualifiée retenue dans la loi. L’objectif affiché par le Ministre de l’Economie dans une tribune du journal Le Monde est d’aider à « retrouver l’esprit industriel du capitalisme » en privilégiant les engagements à long terme de manière à promouvoir des investissements porteurs d’une croissance solide. Cette initiative conduit à reprendre la discussion sur les conditions de gouvernance des sociétés par actions (‘corporations’) (Pollin, 2004, 2006), à examiner les dérives dont elle a pu être l’objet et les remèdes qui ont pu et pourraient dans l’avenir y être apportés, impliquant de savoir ce que peut en attendre le gouvernement.

We study the impact of corporate governance frictions in an economy where growth is driven both by the foundation of new …rms and by the in-house investment of incumbent …rms. Firms’ managers engage in tunneling and empire building activities. Active shareholders monitor man- agers, but can shirk on their monitoring, to the detriment of minority (passive) shareholders. The analysis reveals that these con‡icts among …rms’ stakeholders inhibit the entry of new …rms, thereby increasing market concentration. Despite depressing investment returns in the short run, the frictions can however lead incumbents to invest more aggressively in the long run to exploit the concentrated market structure. By means of quantitative analysis, we characterize conditions under which corporate governance reforms boost or reduce welfare.

The government, buoyed by the law to recapture the real economy, the Florange act, which establishes the possibility of double voting for patient shareholders (who have held their shares at least two years), has just taken two significant decisions by temporarily increasing its holdings in the capital of Renault and Air France in order to ensure that in a general shareholders meeting the double voting option is not rejected by the qualified majority authorized under the law. The objective spelled out by France’s Minister of the Economy in Le Monde is to help “recapture the industrial spirit of capitalism” by favouring long-term commitments in order to promote investment that will foster solid growth. Under the impulse of the Florange law, that has recently introduced the institute of the double voting for ‘patient’ shareholders (shareholders who have held their company’s shares for at least two years), the government has taken the important decision of increasing temporarily its equity shares into two major French companies: Renault and Air France.

This article examines how closely nanotechnology resembles a general purpose technology (GPT). Using patented nanotechnology inventions during 1975-2006, we test for characteristics of GPTs identified in the prior literature, and find evidence that nanotechnology shows both “pervasive” adoption and “spawning” of follow-on innovation. Offering a methodological contribution, we employ concentration indexes such as the Gini index and Lorenz curve to construct “knowledge dissemination curves” for different technologies, thereby providing evidence that nanotechnology shares relevant characteristics with other GPTs. Using an entirely new dataset, we use three different definitions of a “nanotechnology patent” and calculate patent generality indexes, finding that nanotechnology patents are significantly more likely to be referenced across technology space than are patents in information technology, another widely-adopted GPT. In another contribution, we suggest that innovative materials may demonstrate the characteristics of a GPT, and provide a historical parallel between the advancement of steel technology in the 19th Century with that of nanotechnology in the present day.

A society can reap more benefits from an improvement in communication and transportation when the gap between privileged and less-privileged individuals is narrow. This hypothesis is investigated in a Kiyotaki-Wright search environment where people enjoy different rental positions. Historical evidence concerning the rise of Italian seaport cities during the Middle Ages, of the Netherlands in the 17th century, and the nobility ís resistance to trade in pre-revolutionary France is used to support the hypothesis.
