This paper introduces an instrumental variables estimator for the effect of a binary treatment on the quantiles of potential outcomes. The quantile treatment effects (QTE) estimator accommodates exogenous covariates and reduces to quantile regression as a special case when treatment status is...

The view that empirical strategies in economics should be transparent and credible now goes almost without saying. The local average treatment effects (LATE) framework for causal inference helped make this so. The LATE theorem tells us for whom particular instrumental variables (IV) and...

The average effect of intervention or treatment is a parameter of interest in both epidemiology and econometrics. A key difference between applications in the two fields is that epidemiologic research is more likely to involve qualitative outcomes and nonlinear models. An example is the recent...

Time series data are widely used to explore causal relationships, typically in a regression framework with lagged dependent variables. Regression-based causality tests rely on an array of functional form and distributional assumptions for valid causal inference. This paper develops a...

Instrumental Variables (IV) methods identify internally valid causal effects for individuals whose treatment status is manipulable by the instrument at hand. Inference for other populations requires some sort of homogeneity assumption. This paper outlines a theoretical framework that nests all...

This paper analyzes the tax haven investment behavior of multinational firms from a country that exempts foreign income from taxation. High foreign tax rates generally encourage firms to invest in tax havens, though significant costs of reallocating taxable income dampen these incentives. The...

Deferral of U.S. taxes on foreign source income is commonly characterized as a subsidy to foreign investment, as reflected in its inclusion among "tax expenditures" and occasional calls for its repeal. This paper analyzes the extent to which tax deferral and other policies inefficiently...

Using a sample of control cross-border acquisitions from 61 countries from 1990 to 2007, we find that acquirers from countries with better governance gain more from such acquisitions and their gains are higher when targets are from countries with worse governance. Other acquirer country...

This paper analyzes the effect of and performance of foreign direct investment (FDI). sparing foreign investment income to permit investors to receive the full benefits of host country tax reductions. For example, Japanese firms investing in countries with whom Japan has agreements are entitled...

The United States prohibits American individuals and corporations from bribing foreign government officials. Legislation enacted in 1976 and 1977 stipulates tax penalties, fines, and even prison terms for executives of American companies that pay illegal bribes. This paper examines the effect of...
