When credit markets to finance investment in the human capital of young people are missing, the competitive equilibrium allocation is inefficient. When generations overlap, this failure can be mitigated by properly designed social institutions such as public education and public pensions. We...

According to a common argument, the presence of strong intellectual property rights spurs innovation, which then leads to fiercer competition, higher economic growth and increasing benefits for the average consumers. We argue that, in the case of intellectual property rights, this has lead to...

Taking both the enlargement process, as currently defined by the EU, and the structural funds as a given, this Paper examines what is the best way for candidate countries to fuel real convergence. The experience from earlier EU enlargements and current economic conditions within the CEEC10...

It has been argued that concave models exhibit less ‘endogeneity of growth’ than models with increasing returns to scale. Here we study a simple model of factor saving technological improvement in a concave framework. Capital can be used either to reproduce itself, or, at some additional...

We construct a competitive model of innovation and growth under constant returns to scale. Previous models of growth under constant returns cannot model technological innovation. Current models of endogenous innovation rely on the interplay between increasing returns and monopolistic markets. In...

Macroeconomic and microeconomic data paint conflicting pictures of price behaviour. Macroeconomic data suggest that inflation is inertial. Microeconomic data indicate that firms change prices frequently. We formulate and estimate a model that resolves this apparent micro/macro conflict. Our...
