International industry data permits testing whether the industry-specific impact of cross-country differences in institutions or policies is consistent with economic theory. Empirical implementation requires specifying the industry characteristics that determine impact strength. Most of the...

Do high levels of human capital foster economic growth by facilitating technology adoption? If so, countries with more human capital should have adopted more rapidly the skilled-labor augmenting technologies becoming available since the 1970's. High human capital levels should therefore have...

How much would output increase if underdeveloped economies were to increase their levels of schooling? We contribute to the development ac- counting literature by describing a non-parametric upper bound on the increase in output that can be generated by more schooling. The advantage of our...

The identification of aggregate human capital externalities is still not fully understood. The existing (Mincerian) approach confounds positive externalities with wage changes due to a downward sloping demand curve for human capital. As a result, it yields positive externalities even when wages...

This document is a report prepared for for the DG for Employment and Social Affairs of the European Commission. It surveys the available evidence on the contribution of investment in human capital to aggregate productivity growth and on its impact on wages and other labour outcomes at the...

We find that international trade has an economically significant and statistically robust positive effect on productivity. Our trade measure is imports plus exports relative to purchasing power parity GDP (real openness), which we argue is preferable on theoretical grounds to the nominal measure...
