Abstract We analyze the impact of a requirement similar to the Basel III Liquidity Coverage Ratio on the bank intermediation applying Regression Discontinuity Designs. Using a unique dataset on Dutch banks, we show that a liquidity requirement causes long-term borrowing and lending rates as well as demand for long-term interbank loans to increase. Lower levels of aggregate liquidity increase the estimated effects. Short-term borrowing and lending rates only rise during periods of lower market-wide liquidity. Further, banks do not seem able to pass on the increased funding costs in the interbank market to their private sector clients. Rather, a liquidity requirement seems to decrease banks’ interest margins.

FEW WOULD DISAGREE that Adam Smith's invisible-hand theorem is the heart of the economist's Weltanschauung. Ask whether trade barriers should be lowered, the spread of multinational corporations restrained, oil prices deregulated, cartels dissolved, or more fundamentally whether a market-based capitalist system is economically superior to a state-run socialist system, and economists almost certainly will begin to answer the question by trying to apply the theorem. Every student knows that the theorem depends on the assumption of atomistic competition, which in turn assumes that the system is decentralized and that no competitor is large relatively to others. There is another crucial assumption, however, that is often ignored and usually underemphasized, namely that all competition is price competition. In reality one of the most distinctive features of capitalism-one that is most often raised in lay discussions of its merits and demerits-is the prevalence of other forms of competition, such as competition in research, development, and advertising; competition to obtain and hold monopoly; and competition for corporate growth. These various forms of competition, we shall aim to show, are not clearly analogous with the theory of price competition: more non-price competition, rather than less, is not necessarily Pareto optimal. Self-evidently, the production side of a market economy is decentralized only to a limited degree, i.e., to the level of a decision-making unit composed of more than one human. Such a unit-playing Neuron to the Invisible Hand-is typically called a firm. It is in fact a team. Rather than remaining small, firms are in practice composed of any number of individuals from a handful on to half a million. Some

This article provides direct empirical evidence on the relationship between technology and firms’ global sourcing strategies. Using new data on U.S. firms’ decisions to contract for manufacturing services from domestic or foreign suppliers, I show that a firm’s adoption of communication technology between 2002 and 2007 is associated with a 3.1 point increase in its probability of fragmentation. The effect of firm technology also differs significantly across industries; in 2007, it is 20% higher, relative to the mean, in industries with production specifications that are easier to codify in an electronic format. These patterns suggest that technology lowers coordination costs, though its effect is disproportionately higher for domestic rather than foreign sourcing. The larger impact on domestic fragmentation highlights its importance as an alternative to offshoring, and can be explained by complementarities between technology and worker skill. High technology firms and industries are more likely to source from high human capital countries, and the differential impact of technology across industries is strongly increasing in country human capital.

Abstract We use Securities and Exchange Commission (SEC) rule changes to show that regulatory oversight reduces return misreporting by hedge funds. Specifically, we use a 2004 rule change that expanded SEC oversight of hedge funds and the 2006 revocation of this rule. Differences-in-differences tests show that, following the rule change, misreporting by newly regulated funds decreased. After revocation, funds that exited the regulatory system increased misreporting relative to funds that remained registered. Placebo tests show no change in misreporting by foreign funds exempt from the rule change. We show that regulatory oversight increased the level of flows and decreased the sensitivity of flows to underperformance.

We study torture as a mechanism for extracting information from a suspect who may or may not be informed. We show that a standard rationale for torture generates two commitment problems. First, the principal would benefit from a commitment to torture a suspect he knows to be innocent. Secondly, the principal would benefit from a commitment to limit the amount of torture faced by the guilty. We analyse a dynamic model of torture in which the credibility of these threats and promises is endogenous. We show that these commitment problems dramatically reduce the value of torture and can even render it completely ineffective. We use our model to address questions such as the effect of enhanced interrogation techniques, rights against indefinite detention, and delegation of torture to specialists.

This paper examines the determinants of CDS spreads and potential spillover effects for Eurozone countries during the recent financial crisis in the EU. We employ a Panel Vector Autoregressive (PVAR) model which combines the advantages of traditional VAR modelling with those of a panel-data approach. In addition to variables that proxy for global and financial market spread determinants we also employ variables that proxy for behavioral determinants. We find that the determinants of CDS variance are neither uniform nor stable during different periods and different countries. For instance, as we move from 2008 to 2014 the impact of the slope of the term structure on CDS spread variance is increasing for peripheral countries such as Spain, Portugal, Italy, Greece, Ireland, and decreasing for core countries such as Germany, France, Netherlands, Belgium and Austria. Other findings indicate that investor sentiment was an important CDS spread determinant during the subprime crisis, along with other factors, while spillover effects run from larger peripheral economies such as Spain and Italy to core countries; spillover effects from Portugal, Greece, and Ireland are of minor importance.

The Home Affordable Modification Program's (HAMP's) Principal Reduction Alternative (PRA) is a government-sponsored program to reduce the principal balances and monthly mortgage payments of troubled borrowers. We examine the effect of principal forgiveness on borrowers' subsequent mortgage default. The program's rules imply a kink in the relationship between principal forgiveness and a borrower's initial equity level. Our identification strategy exploits the quasi-experimental variation in principal forgiveness generated by this kink using a regression kink design (RKD), which compares the relationship between initial equity and default on either side of the kink. We estimate that HAMP PRA reduced the quarterly default hazard from 3.8% to 3.1%.

We show that healthcare providers face a tradeoff between increasing the number of patients they treat and improving their quality of care. To measure the magnitude of this quality-quantity tradeoff, we estimate a model of dialysis provision that explicitly incorporates a centre’s unobservable and endogenous choice of treatment quality while allowing for unobserved differences in productivity across centres. We find that a centre that reduces its quality standards such that its expected rate of septic infections increases by 1 percentage point can increase its patient load by 1.6%, holding productivity, capital, and labour fixed; this corresponds to an elasticity of quantity with respect to quality of -0.2. Notably, our approach provides estimates of productivity that control for differences in quality, whereas traditional methods would misattribute lower-quality care to greater productivity.

Understanding the employment dynamics of disadvantaged families is increasingly important. We estimate duration models describing these dynamics for disadvantaged single mothers and use them to conduct a rich set of counterfactual analyses. We use a misreporting model to correct for “seam bias,” the problem that too many transitions are reported between reference periods in panel data. We find effects of demographics, minimum wages, unemployment rates, and maximum welfare benefits, but not policy changes introduced through state welfare waivers, on employment dynamics. We find that two commonly used ad hoc methods of addressing seam bias perform substantially worse than our approach.

In nursing this essay through several drafts, I have benefited greatly from suggestions by Edward Denison, Robert Evenson, Zvi Griliches, Richard Levin, John Kendrick, Edwin Mansfield, and Richard Murnane. Moses Abramovitz has been a source ofencouragement and good, substantive editorial advice, for which I am most grateful. The heterodox views are my own, although I share many of them with Sidney Winter.
