The geographical distribution of R&D investment changes dramatically in the 1970s and 1980s. In the early 1970s U.S. firms are the uncontested world leaders in R&D investment in most manufacturing sectors. Later, led by Japan and Europe, foreign firms start challenging American R&D leadership in...

In this paper I examine the effects of international technological competition on innovation, growth, and optimal R&D subsidies. I focus on a particular dimension of competition: the share of industries where domestic and foreign research firms compete for innovation. In a version of the...

In this paper we argue that government procurement policy played a role in stimulating the wave of innovation that hit the US economy in the 1980s, as well as the simultaneous increase in inequality and in education attainment. Since the early 1980s U.S. policy makers began targeting commercial...

This paper studies the welfare effects of international competition in the market for innovations, and analyzes how competition affects the costs and the benefits of cooperative and non-cooperative R&D subsidies. I set up a two-country quality-ladder growth model where the leader, the home...

Increasing wage inequality between similar workers plays an important role for overall inequality trends in industrialized societies. To analyze this pattern, we incorporate directed labor market search into a dynamic model of international trade with heterogeneous firms and homogeneous workers....

This paper introduces idiosyncratic firm efficiency shocks into a continuous-time general equilibrium model of trade with heterogeneous firms. The presence of sunk export entry costs and efficiency uncertainty gives rise to hysteresis in export market participation. A firm will enter into the...

In this paper we argue that government spending played a significant role in stimulating the wave of innovation that hit the U.S. economy in the late 1970s and in the 1980s, as well as the simultaneous increase in inequality and in education attainments. Since the late 1970s U.S. policymakers...

International technological competition implied by the global distribution of R&D investment changed dramatically in the 1970s and 1980s. In the early 1970s the distribution is very skewed: US firms were the uncontested world leaders in research investment in most manufacturing sectors. Later,...
