We provide strong evidence of advantageous selection in the Medigap insurance market, and analyze its sources. Using Medicare Current Beneficiary Survey (MCBS) data, we find that, conditional on controls for the price of Medigap, medical expenditures for senior citizens with Medigap coverage...

In this paper, we provide estimates of welfare benefit effects on a set of behaviors that includes welfare participation, fertility, marriage, work and schooling using approximations to the decision rules that would be derived from an explicit dynamic optimization problem. The estimates are...

This paper develops generalized method-of-moments tests for the rationality of earnings per share forecasts made by individual stock analysts. We fail to reject the hypothesis of rationality as long as we take into account two complications: (1) the correlation in a given period of analysts'...

A strong positive association between one's school attainment and that of one's parents has been consistently documented in numerous empirical studies. The underlying cause of this intergenerational correlation has been the subject of contentious debate in the social sciences for many years. Two...

Opportunities for external validation of behavioral models in the social sciences that are based on randomized social experiments or on large regime shifts, that can be treated as experiments for the purpose of model validation, are extremely rare. In this paper, we consider an alternative...

We study the resource allocation decisions of U.S. multinational corporations (MNCs). We examine how established MNCs grow across countries over time and how firm-specific resources and host country financial-market development influence MNCs' growth across their networks of affiliates. We find...

Using Confidential Data on 1300 U.S.-based multinational corporations (MNCs), we examine whether MNCs that moved jobs out of Canada between 1983 and 2003 systematically moved the jobs elsewhere within the MNC. We also look at whether trends in the movement of jobs within MNCs differ for...

Researchers have found mixed results on whether FDI generates positive spillovers that improve the efficiency of host country economies. We argue that these inconclusive results may be due (in part) to the substantial heterogeneity in MNC affiliate activity, which prior research has largely...
