TL;DR: In this paper, the authors examine a dataset of laws and practices governing public procurement, as well as procurement outcomes, in 187 countries and find evidence broadly consistent with this prediction: regulation of procurement improves outcomes but only in countries with low public sector capacity.
Abstract: In this paper we examine a new dataset of laws and practices governing public procurement, as well as procurement outcomes, in 187 countries. We measure regulation as restrictions on the discretion of the procuring agents. We find that laws and practices are highly correlated with each other across countries, and better practices are correlated with better outcomes, but laws themselves are not correlated with outcomes. To shed light on this puzzle, we present a model of procurement in which both regulation and public sector capacity determine the efficiency of procurement. In the model, regulation is effective in countries with low public sector capacity, and detrimental in countries with high public sector capacity because it inhibits the socially optimal exercise of discretion. We find evidence broadly consistent with this prediction: Regulation of procurement improves outcomes but only in countries with low public sector capacity.

TL;DR: In this paper, the authors describe an economy where a durable good is produced with an increasing returns to scale technology, and the model is consistent with a broad range of evidence on economic fluctuations.
Abstract: We describe an economy where a durable good is produced with an increasing returns to scale technology. Equilibria in this economy take the form of business cycles in which consumption fluctuates too much and is too low on average. A 2-sector version of this economy with imperfect credit and immobile labor also exhibits aggregate business cycles, in which outputs and labor inputs in different sectors move together. The model is consistent with a broad range of evidence on economic fluctuations.

TL;DR: The 2014 John Bates Clark Medal of the American Economic Association was given to Matthew Gentzkow of the University of Chicago Booth School of Business as discussed by the authors, who made fundamental contributions to our understanding of the economic forces driving the creation of media products, the changing nature and role of media in the digital environment and the effect of media on education and civic engagement.
Abstract: The 2014 John Bates Clark Medal of the American Economic Association was awarded to Matthew Gentzkow of the University of Chicago Booth School of Business. The citation recognized Matt's “fundamental contributions to our understanding of the economic forces driving the creation of media products, the changing nature and role of media in the digital environment, and the effect of media on education and civic engagement.” In addition to his work on the media, Matt has made a number of significant contributions to empirical industrial organization more broadly, as well as to applied economic theory. In this essay, I highlight some of these contributions.

TL;DR: In this paper, the authors present a model of investment hangover motivated by the Great Recession, where overbuilding of residential capital requires a reallocation of productive resources to nonresidential sectors, which is facilitated by a reduction in the real interest rate.
Abstract: We present a model of investment hangover motivated by the Great Recession. In our model, overbuilding of residential capital requires a reallocation of productive resources to nonresidential sectors, which is facilitated by a reduction in the real interest rate. If the fall in the interest rate is limited by the zero lower bound and nominal rigidities, then the economy enters a liquidity trap with limited reallocation and low output. The drop in output reduces nonresidential investment through a mechanism similar to the acceleration principle of investment. The burst in nonresidential investment is followed by an even greater boom due to low interest rates during the liquidity trap. The boom in nonresidential investment induces a partial and asymmetric recovery in which the residential sector is left behind, consistent with the broad trends of the Great Recession.Institutional subscribers to the NBER working paper series, and residents of developing countries may download this paper without additional charge at www.nber.org.

TL;DR: This paper examined legal rules covering protection of corporate shareholders and creditors, the origin of these rules, and the quality of their enforcement in 49 countries and found that common law countries generally have the best, and French civil law countries the worst, legal protections of investors.
Abstract: This paper examines legal rules covering protection of corporate shareholders and creditors, the origin of these rules, and the quality of their enforcement in 49 countries. The results show that common law countries generally have the best, and French civil law countries the worst, legal protections of investors, with German and Scandinavian civil law countries located in the middle. We also find that concentration of ownership of shares in the largest public companies is negatively related to investor protections, consistent with the hypothesis that small, diversified shareholders are unlikely to be important in countries that fail to protect their rights.

TL;DR: Corporate Governance as mentioned in this paper surveys research on corporate governance, with special attention to the importance of legal protection of investors and of ownership concentration in corporate governance systems around the world, and shows that most advanced market economies have solved the problem of corporate governance at least reasonably well, in that they have assured the flows of enormous amounts of capital to firms, and actual repatriation of profits to the providers of finance.
Abstract: This article surveys research on corporate governance, with special attention to the importance of legal protection of investors and of ownership concentration in corporate governance systems around the world. CORPORATE GOVERNANCE DEALS WITH the ways in which suppliers of finance to corporations assure themselves of getting a return on their investment. How do the suppliers of finance get managers to return some of the profits to them? How do they make sure that managers do not steal the capital they supply or invest it in bad projects? How do suppliers of finance control managers? At first glance, it is not entirely obvious why the suppliers of capital get anything back. After all, they part with their money, and have little to contribute to the enterprise afterward. The professional managers or entrepreneurs who run the firms might as well abscond with the money. Although they sometimes do, usually they do not. Most advanced market economies have solved the problem of corporate governance at least reasonably well, in that they have assured the flows of enormous amounts of capital to firms, and actual repatriation of profits to the providers of finance. But this does not imply that they have solved the corporate governance problem perfectly, or that the corporate governance mechanisms cannot be improved. In fact, the subject of corporate governance is of enormous practical impor

TL;DR: In this article, the authors show that strategies that buy stocks that have performed well in the past and sell stocks that had performed poorly in past years generate significant positive returns over 3- to 12-month holding periods.
Abstract: This paper documents that strategies which buy stocks that have performed well in the past and sell stocks that have performed poorly in the past generate significant positive returns over 3- to 12-month holding periods. We find that the profitability of these strategies are not due to their systematic risk or to delayed stock price reactions to common factors. However, part of the abnormal returns generated in the first year after portfolio formation dissipates in the following two years. A similar pattern of returns around the earnings announcements of past winners and losers is also documented
