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...

We compare the relation between foreign affiliate production and parent employment in U.S. manufacturing multinationals with that in Swedish firms. U.S. multinationals appear to have allocated some of their more labor intensive operations selling in world markets to affiliates in developing...

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...

A longstanding question in the economics of the family is the relationship between sibship size and subsequent human capital formation and economic welfare. If there is a "quantity-quality trade-off," then policies that discourage large families should lead to increased human capital, higher...

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...

Inward and outward direct investment (FDI) stocks and flows tend to go together, across countries and over time. The countries that invest extensively abroad are usually also large recipients of FDI. There is little evidence that flows of FDI are a major influence on capital formation. That lack...

Direct investment has accounted for about a quarter of total international capital outflows in the 1990s and appears to have grown, relative to other forms of international investment, since the 1970s. The United States was by far the major source of direct investment outflows in the early...

This paper examines how inward and outward foreign direct investment (FDI) have influenced the restructuring of the Japanese economy and can be expected to continue to do so in the future. We find that outward investment has helped Japanese firms to sustain foreign market shares and contributed...

Within Japanese multinational firms, parent exports from Japan to a foreign region are positively related to production in that region by affiliates of that parent, given the parent's home production in Japan and the region's size and income level. This relationship is similar to that found for...
