This paper studies a two-country production economy with complete and frictionless financial markets and international trade of final goods in which competition in R&D leads to endogenous new firm creation and economic growth. Current monopolists ("incumbents") and potential new firms...

We investigate the impact of incremental trade liberalization in a dynamic model of endogenous growth with heterogeneous firms and costly trade. Growth originates from horizontal specialization and the steady state productivity growth rate is positive. Innovations require costly R&D and are...

This paper provides a rationale for the revival of protectionism, based on the rise of the educated class. In a trade model with heterogeneous workers and entrepreneurs, globalization generates aggregate gains but has distributional effects, which can be attenuated through taxation. By playing a...

Regulatory reform efforts in a broad range of industries have resulted in increased importance of competitive forces as a means to allocate resources and improve economic efficiency. A number of indicators suggest that such forces have been stronger in the United States than in most other OECD...

We develop an endogenous growth model to quantify how permanent structural policy changes that enhance the fiscal policy mix, markets' functioning, and public institutions' quality affect long-term growth and welfare. The reforms include increased public investment, reduced market power through...

Governments purchase everything from airplanes to zucchini. This paper investigates the role of the technological content of government procurement in innovation. We theoretically show that a shift in the composition of public purchases toward high-tech products translates into higher...

This paper develops an open economy growth model in which firm heterogeneity increases the gains from trade. Technology spillovers from incumbent firms to entrants cause the productivity threshold for firm survival to grow over time as competition becomes tougher. By raising the profits of...

Labor's share of income has attracted interest in recent years reflecting its apparent decline. These falls, witnessed across many countries, are usually deemed undesirable. Any such assertion, however, begs the question of what is the socially optimal labor share. We address this question using...

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor...

Empirical research based on the Bhaduri/Marglin-variant of the Kaleckian model has recently shown that aggregate demand in many medium-sized and large open economies tends to be wage-led in the medium to long run, even in a period of increasing globalisation. In this paper we extend this type of...
