The paper investigates the determinants of geographical distribution of international currencies in global financial market transactions. We implement a gravity model, in which international currency distribution depends on the characteristics of the source and destination countries. We find...

This paper estimates two measures of human capital externalities. By incorporating externalities into an overlapping-generations model of human capital accumulation with Compulsory Schooling Laws (CSL), we show that human capital externalities can be estimated from the effects of CSL for one...

We estimate a model of high school students' college choices, allowing for rich heterogeneity in students' preferences for college attributes. We use data on students' enrollment decisions and application decisions--i.e., the sets of colleges to which they applied--to identify the distribution...

We consider inference for predictive regressions with multiple predictors. Extant tests for predictability may perform unsatisfactorily and tend to discover spurious predictability as the number of predictors increases. We propose a battery of new instrumental-variables based tests which involve...
