This econometric analysis investigates the impact of changes in sectoral valueadded prices and total factor productivity (TFP) on the equilibrium relative wage of low-skilled workers in eleven high-income countries. The key finding is that TFP growth mandated an increase in the unskilled wage,...

The secular shift in labor demand from unskilled to skilled labor is explained within a model that is solved numerically. There are three branches producing a basic good, a differentiated luxury good, and an intermediate service. Production is more skill-intensive in the luxury good and the...

In this paper the seasonal unit root test of Hylleberg et al. (1990) is generalized to cover a heterogenous panel. The procedure follows the work of Im, Pesaran and Shin (2002). Test statistics are proposed and critical values are obtained by simulations. Moreover, the properties of the tests...

We present a two-step approach of assessing whether major donors of foreign aid have met recent demands for less proliferated and better coordinated aid efforts. First, we calculate Theil indices revealing the concentration of each donor's aid on recipient countries and specific aid sectors....

A recent literature has pointed at potential negative effects of exchange rate volatility on innovation. In this paper, we propose that there may be a direct effect as well as an indirect effect via export activity. We test these hypotheses for sectoral R&D intensities using OECD panel data for...

We estimate the relative roles of factor inputs and productivity in explaining the level of economic development, which is measured as output per worker. For a large sample of countries, we show that alternative identifying productivity assumptions and alternative measures of human capital have...

Based on Baumol’s cost-disease model, we develop two alternative measures of the change in the productivity of schooling. Both productivity measures are based on changes in the relative price of schooling. We find that in most OECD countries the price of schooling has increased faster in...
