Wage Effects of High-Skilled Migration: International Evidence This paper argues that international migration of high-skilled workers triggers productivity effects at the macro level such that the wage rate of skilled workers may rise in host countries and decline in source countries. We exploit a recent data set on international bilateral migration flows and provide evidence which is consisten...
We introduce endogenous directed technical change into integrated climate policy assessment. Our model builds on state-of-the-art theory as well as econometric data. We apply our model to the assessment of a carbon budget based climate policy. Motivated by the announcement of international transfers during recent climate policy negotiations, we vary the begin of endogenous international transfe...
In this paper, using a production framework in which skilled and unskilled labor are imperfect substitutes, I analyze the time paths of the efficiencies of skilled and unskilled labor and their implications for economic growth and wage inequality in the US between 1950 and 2005. There are two main findings. First, I find that skilled labor efficiency has grown more slowly since the mid 1970s. S...
Both the quality and quantity of human capital are important for growth. Although the quality aspects of human capital may have greater potential in explaining growth, given that the quantity effects of human capital have been found to be ambiguous, they have long been ignored in empirical growth literature. This paper empirically tests the joint effects of both the quantity and quality of huma...
In the model where the choice of technology by firms endogenously determines productivity differences, we investigate the link between factor endowment and the productivity both in the firm and industry levels. We find among others that firms in capital-abundant countries tend to adopt new advanced technologies more in their production processes, but opening to international trade will equalize...
This paper studies product innovation and firm survival in the U.S. ATM/debit card industry. The industry started with a few shared ATM networks in the early 1970s. The number of networks grew quickly up until the mid 1980s, but then declined sharply. We construct a theoretical model based on Jovanovic and MacDonald (1994). In contrast to their model focusing on cost-saving technological innova...
This paper analyzes firms’ choices regarding the geographic scope of patent protection within the European patent system. We develop an econometric model at the patent level to quantify the impact of office fees and translation costs on firms’ decision to validate a patent in a particular country once it has been granted by the EPO. These costs have been disregarded in previous studies. The res...
in more recent years, it has become increasingly recognized that r&d; (research and development) is a key driver of economic growth, a source of innovation and change, and as such stimulates improvements in productivity and economic competitiveness. it is closely associated with knowledge and flexibility, two factors that have gained new significance as a source of competitiveness in an increas...
The paper investigates structural change among the four-digit (SIC) industries of the U.S. manufacturing sector during 1958-96 within a distribution dynamics framework. Focus is on the transition density of the Markov process that characterizes the value added shares of the industries. This transition density is estimated nonparametrically as well as by maximum likelihood, in which case the fun...
This paper provides an overview of the treatment of technological change in economic models of environmental policy. Numerous economic modeling studies have confirmed the sensitivity of midand long-run climate change mitigation cost and benefit projections to assumptions about technology costs. In general, technical progress is considered to be a noneconomic, exogenous variable in global climat...
