We construct an equilibrium model of firm diversification to show that the main empirical findings about firm diversification and performance are consistent with the maximization of shareholder value. In our model, diversification allows a firm to explore better productive opportunities while...

This Paper suggests that skill accumulation through past work experience, or ‘learning-by-doing’ (LBD), can provide an important propagation mechanism in a dynamic stochastic general equilibrium model, as the current labour supply affects future productivity. Our econometric analysis uses a...

We incorporate costly external finance in a production based asset pricing model and investigate whether financing frictions are quantitatively important for pricing a cross-section of expected returns. We show that the common assumptions about the nature of the financing frictions are captured...

A search-theoretic general equilibrium model of frictional unemployment is shown to be consistent with some of the key regularities of unemployment over the business cycle. In the model the return to a job moves stochastically. Agents can choose either to quit and search for a better job, or...

This Paper asks whether the asset pricing fluctuations induced by the presence of costly external finance are empirically plausible. To accomplish this, we incorporate costly external finance into a dynamic stochastic general equilibrium model and explore its implications for the properties of...

We explicitly link expected stock returns to firm characteristics such as firm size and book-to-market ratio in a dynamic general equilibrium production economy. Despite the fact that stock returns in the model are characterized by an intertemporal CAPM with the market portfolio as the only...

This paper employs cohort technique and Consumer Expenditure Survey data to construct average age-profiles of consumption and income over the working lives of typical households across different education and occupation groups. Using these profiles, we estimate a structural model of optimal...

We offer a duality-based methodology for incorporating multi-sector effects of international trade into open economy macroeconomic models, developing the concepts of the dynamic factor price equalization set and the integrated intertemporal equilibrium. Under this approach, the aggregate...

The paper shows that the conversion from national currency bank notes to hard-ECU notes is promoted by the provision of an implicit and free currency call option. This wealth effect is caused by the devaluation-proof definition of this currency. Nevertheless, additional transactions and...

This paper is intended to make four main points that are relevant for previously planned economies in transition to a market economy. First, national output can be increased by reducing or eliminating relative price distortions through price reform and free trade and by thus enhancing...
