This paper uses nonparametric kernel methods to construct observation-specific elasticities of substitution for a balanced panel of 73 developed and developing countries to examine the capital-skill complementarity hypothesis. The exercise shows some support for capital-skill complementarity,...

We perform a meta-analysis of 110 studies that report simulated global welfare gains from trade liberalization under the WTO Doha Development Agenda (DDA) to test for hidden, author-specific model specification effects. We find that after controlling for other factors that influence simulation...

Economists use partial and general equilibrium trade simulation models to estimate the impact of changes in domestic policies and international trade rules. During the WTO Doha Development Agenda (DDA) negotiations economists have produced many different estimates of the gains that would result...

The Africa-Dummy has been identfied and different explanations for its appearance have been published. In this paper, the issue of the empirical identifcation of the Africa-Dummy is addressed. We introduce a fixed eff ects regression model to identify the Africa-Dummy in one regression step so...

Empirical growth regressions typically include mean years of schooling as a proxy for human capital. However, empirical research often finds that the sign and significance of schooling depends on the sample of observations or the specification of the model. We use a nonparametric local-linear...
