Whether or not the marginal product of capital (MPK) differs across countries is a question that keeps coming up in discussions of comparative economic development and patterns of capital flows. Attempts to provide an empirical answer to this question have so far been mostly indirect and based...

The response of an economy to a windfall of foreign exchange (be it aid or natural resource revenues) is often constrained by absorptive capacity. We provide a micro-founded analysis of absorption constraints, based on the idea that expanding the economy’s capital stock (in aggregate or...

Political risk is widely present in developing but also in developed countries, and stems from a variety of sources. The objective of this paper is twofold. First, we develop a theoretical model to investigate the impact of political risk on irreversible investment. Second, we apply our model to...

We study the macroeconomic effects of rational asset bubbles in an overlapping-generations economy where asset trading requires specialized intermediaries and where agents freely choose between working in the production or in the financial sector. Frictions in the market for deposits create...

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 presents evidence supporting the theory that informational and incentive problems in capital markets affect firm investment. This hypothesis is tested by estimating investment equations for two groups of German manufacturing firms. The first group of firms are those with bank...

This paper adds a highly-leveraged financial sector to the Ramsey model of economic growth and shows that this causes the economy to behave in a highly volatile manner: doing this strongly augments the macroeconomic effects of aggregate productivity shocks. Our model is built on the financial...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value added output, we calculate for each state the efficient frontier for investments in the real economy, the efficient Sharpe...

This paper reformulates the well known financial development conjecture (FDC) and supplies some new empirical evidence in its favour. The financial development conjecture, namely, that there exist strong feedback effects between real and financial development, is described in this paper by use...
