摘要：This paper empirically tests for a multidimensional separating equilibrium in contract negotiations and tests for evidence of the moral hazard inherent in many contracts. Using contract and performance data on players drafted into the National Football League from 1986 through 1991, we find evidence that players use delay to agreement and incentive clauses to reveal their private information during contract negotiations. In addition, our empirical tests of the moral hazard issue indicate that ...

摘要：Proxy variables are frequently used in economics to control for unavailable variables in a linear regression setting. For example, AFQT scores have been used to control for human capital accumulation in measuring black-white wage differentials. This practice may bias the coefficient estimates for the correctly measured variables as well. This paper models proxy variables as a measurement error process and derives bounds for the coefficients on the correctly measured variables under a variety o...

摘要：This paper examines the effect of drug prohibition on the black market prices of cocaine and heroin. The paper examines the ratio of retail to farmgate price for cocaine, heroin, and several legal goods, and it compares legal versus black market prices for cocaine and heroin. The results suggest that cocaine and heroin are substantially more expensive than they would be in a legalized market, but to a lesser degree than suggested in previous research.

摘要：This paper reports the results of an empirical study of the industry and country determinants of U.S. outward foreign direct investment (FDI). These results contribute to the literature in two dimensions. First, they demonstrate that the structure of U.S. FDI reflects an interaction between country skilled-labor abundance and industry skilled-labor intensities that is consistent with comparative advantage. Second, they confirm the results of early studies that market access plays an important ...

摘要：This paper examines precautionary behavior by relating job-loss risk to household net worth. We use existing best practice and some new strategies to deal with some problematic issues inherent in this literature regarding proxying uncertainty, instrumentation, and incorporating theoretical restrictions. We do not find precautionary variation in the wealth holdings of households with low permanent income, but do find precautionary effects for moderate and higher-income households. When the depe...

摘要：Inspired by the recent literature on aggregation theory, this paper introduces HITS, a semiparametric model of consumer demand that allows for diversity in tastes. The strong variation of budget shares observed across income groups has two possible origins: the individual income effect, and taste differences between poor and rich households. Consumer surveys reporting repeated cross sections do not permit the direct measurement of these two effects. In HITS, linear heterogeneity allows the GMM...

摘要：A youth homicide reduction initiative in Boston in the mid-1990s poses particular difficulties for program evaluation because it did not have a control group and the exact implementation date is unknown. A standard methodology in program evaluation is to use time series variation to compare pre- and postprogram outcomes. Such an approach is not valid, however, when the timing of program implementation or effect is unknown. To evaluate the Boston initiative, we adapt from the time series litera...

摘要：In a cross-country data set for developing and transitional economies, private consumption per capita from the national accounts deviates on average from mean household income or expenditure based on national sample surveys. Growth rates also differ systematically, so that the ratio of the survey mean to mean consumption from the national accounts tends to fall over time. The exceptions to these general findings are revealing, however. There are strong regional effects. The aggregate differenc...

摘要：We investigate whether fluctuations in U.S. inflation rates are better described by infrequently occurring large shocks or by frequently occurring small shocks. We estimate a model that encompasses the two hypotheses within the framework of non-Gaussian state-space models. Our results indicate support for infrequently occurring large shocks, but this weakens somewhat once we allow for outliers and conditional heteroskedasticity. It appears that, for the purpose of forecasting monthly U.S. infl...

摘要：This paper calculates elasticities of demand for race groups in South Africa, government-revenue-maximizing tax rates, and excess burdens associated with taxes. A change in tax policy can be the political engine of income redistribution with appropriate taxes and subsidies on different commodities. This paper compares both semiparametric and parametric estimators with the censored least absolute deviation and censored maximum likelihood in calculating demand equations and elasticities. It is f...
