Evidence for the United States suggests balanced growth despite falling investment-good prices and less than unitary elasticity of substitution between capital and labor. This is inconsistent with the Uzawa Growth Theorem. We extend Uzawa.s theorem to show that introducing human capital...

We develop an equilibrium model of industrial structure in which the organization of firms is endogenous. Differentiated consumer products can be produced either by vertically integrated firms or by pairs of specialized companies. Production of each variety of consumer good requires a unique,...

Labour incomes depend on structural as well as politico-economic factors, because labour market policies partially remedy the financial market imperfections that make labour income shocks difficult to insure, and have different implications for labour and capital income. This paper illustrates...

We study the incentives that governments have to protect intellectual property in a trading world economy. We consider a world economy with ongoing innovation in two countries that differ in market size and in their capacities for innovation. We associate the strength of IPR protection with the...

"Race-to-the-bottom" deregulation is to be expected when markets operate across the borders of countries that independently choose and enforce labor policies. Less obviously, in pre-crisis EMU reforms of labor market policies were uneven and related to international imbalances. That pattern is...

We study the incentives that governments have to protect intellectual property in a trading world economy. We consider a world economy with ongoing innovation in two countries that differ in market size and in their capacities for innovation. We associate the strength of IPR protection with the...

This paper proposes a stylized model of policy determination and imperfect international integration. A country-specific policy wedge corrects labor market imperfections and/or redistributes welfare across differently wealthy agents. Capital market integration with the rest of the world, indexed...

We consider an economic geography setting in which firms are free to choose one of the following organizational types: (i) integrated firms, which perform all their activities at the same location, (ii) horizontal firms, which operate several plants producing the same good at different...

Trading the cost of better performance off the probability that an imprecise test’s performance estimate falls short of the pass threshold, an assessee may perform above the threshold (and fear failure because of negative errors) or below it (and hope to pass because of positive errors). This...
