摘要：We construct a model where the equilibrium organization of firms changes as an economy approaches the world technology frontier. In vertically integrated firms, owners (managers) have to spend time both on production and innovation activities, and this creates managerial overload, and discourages innovation. Outsourcing of some production activities mitigates the managerial overload, but creates a holdup problem, causing some of the rents of the owners to be dissipated to the supplier. Far fro...

摘要：Hookworm and malaria, parasites that remain a significant public health threat in the tropical belt today, were endemic in the American South as late as the first half of the twentieth century. I discuss how the successful eradication of malaria and hookworm in the American South affected human-capital accumulation. I find that areas that had higher levels of (malaria or hookworm) infection prior to eradication experienced greater increases in school attendance and literacy afterwards. Moreove...

摘要：This paper deals with Science and Technology in research policy. Following recent literature on the economics of knowledge, Science and Technology are defined as distinct institutional arrangements, broadly corresponding to nonmarket and market allocation mechanisms. Previous analyses argued that Science and Technology can and should coexist within an economic system or society. This paper shows that Science and Technology tend to coexist-and should coexist on welfare grounds-also within the s...

摘要：This paper exploits dynamic features of insurance contracts in the empirical analysis of moral hazard. We first show that experience rating implies negative occurrence dependence under moral hazard: individual claim intensities decrease with the number of past claims. We then show that dynamic insurance data allow to distinguish this moral-hazard effect from dynamic selection on unobservables. We develop nonparametric tests and estimate a flexible parametric model. We find no evidence of moral...

摘要：This paper presents an overview of the results of a research project on monetary transmission pursued by the Eurosystem, which has analyzed micro data on firms and banks in several countries of the euro area in great detail. There is strong empirical support for an interest rate channel working through firm investment. Furthermore, a credit channel can be identified with firm micro data. On the bank side, there is evidence that lending reacts differently to monetary policy according to bank ba...

摘要：This paper analyzes the interactions between growth and the contracting environment in production. With incompleteness in contracting, a firm's capacity to commit to its workers will depend on institutional frictions such as hiring and firing costs. This interaction of contracting structure and relationship costs will in part determine firms' technology choices. We suggest this as a possible explanation of the differential rates of labor productivity growth in Europe and the United States. (JE...

摘要：Aggregate data is often used to make inferences about individual level behavior. If there are social interactions in which one person's actions influence his neighbor's incentives or information, then these inferences are inappropriate. The presence of positive social interactions, or strategic complementarities, implies the existence of a social multiplier where aggregate relationships will overstate individual elasticities. We present a brief model and then estimate the size of the social mu...

摘要：This paper reviews some puzzling economic aspects of globalization and argues that they cannot be satisfactorily addressed in perfectly or monopolistically competitive models. Drawing on recent work, a model of oligopoly in general equilibrium is sketched. The model ensures theoretical consistency by assuming that firms are large in their own markets but small in the economy as a whole, and ensures tractability by assuming quadratic preferences defined over a continuum of goods. Applications c...

摘要：Since 1979, the Bureau of Labor Statistics (BLS) has nearly quadrupled the size of the sample used to estimate monthly employment changes. Although first-reported employment estimates are still noisy, the magnitude of sampling variability has declined in proportion to the increase in the sample size. A model of rational Bayesian updating predicts that investors would assign more weight to the BLS employment survey as it became more precise. However, a regression analysis of changes in interest...
