Many successful examples of economic development, such as South Korea, exhibit long periods of sustained capital accumulation. This process is characterized by a gradually rising investment rate along with a moderate rate of return to capital, both of which are strongly at odds with the standard...

This essay discusses the reasons for and implications of the decline in real interest rates around the world over the past several decades. It suggests that the decline in interest rates is largely explicable from trends in saving, growth, and markups. In this environment, greater government...

How important is financial development for economic development? A costly state verification modelof financial intermediation is presented to address this question. The model is calibrated to match factsabout the U.S. economy, such as intermediation spreads and the firm-size distribution for the...

Consumption and investment comove over the business cycle in response to shocks that permanently move the price of investment. The interpretation of these shocks has relied on standard one-sector models or on models with two or more sectors that can be aggregated. However, the same...

This paper analyses the effects of disease and war on the accumulation of human and physical capital. We employ an overlapping-generations frame-work in which young adults, confronted with such hazards and motivated by old-age provision and altruism, make decisions about investments in schooling...

This paper evaluates the relative contribution of factor accumulation and technology in explaining output per worker differences across Italian regions in the period 2000-2004. The contributions of physical and human capital are separately estimated through the variance decomposition of output...

This paper analyses the effects of disease and war on the accumulation of human and physical capital. We employ an overlapping-generations frame-work in which young adults, confronted with such hazards and motivated by old-age provision and altruism, make decisions about investments in schooling...

This paper presents an interpretation of post-1953 Colombian economic growth and a discussion on future outcomes. The interpretation takes the form of a data playback guided by the decentralized equilibrium version of the Cass-Koopmans-Ramsey model. The role of technical change as a driver of...

Over the past four decades, real interest rates have risen then fallen across the industrialised world. Over the same period, nominal investment rates fell, while house prices and household debt ratios rose. I explain these four trends with a fifth — the widespread fall in the relative price...

We present a dynamic general equilibrium model with heterogeneous firms. Owners of the firms delegate investment decisions to managers, whose consumption and investment are private information. We solve the optimal incentive compatible contracts and characterize the implied firm dynamics....
