This paper examines the global macro-dynamics of an OLG model with capital and land with rational expectations. Through the interactions between capital accumulation and land prices, the economy experiences phase transitions, endogenously moving back and forth from situations with unique and...

Deficit finance is free when the growth rate routinely exceeds the government's borrowing rate. Or so many people say. This note presents three counterexamples. Each features a simple OLG economy with a zero growth rate and a negative government borrowing rate. None provides a basis for taking...

Carbon taxation is a widely proposed and in some countries already adopted means to limit anthropogenic climate change. This paper studies carbon taxation using an 18-region, 80- period overlapping generations model. We focus on carbon policy that delivers present and future mankind the highest...

We use a sufficient statistic approach to quantify the general equilibrium effects of population aging on wealth accumulation, expected asset returns, and global imbalances. Combining population forecasts with household survey data from 25 countries, we measure the compositional effect of aging:...

Population aging has been linked to a global savings glut and a decline in safe real interest rates. Conversely, risky real returns have not fallen as much, if at all, with equity risk premia on the rise. An existing literature can explain changes in safe rates using demographics. We go further...

The modern financial system features complicated financial intermediation chains, with each layer performing a certain degree of credit/maturity transformation. We develop a dynamic model in which an entrepreneur borrows from overlapping-generation households via layers of funds, forming a...

This paper analyzes exchange rate management in a simple overlapping generations model. This framework is used to evaluate alternative policies in terms of their implications for the welfare of individuals in the economy.The analysis identifies two objectives of monetary policy,providing...

The main arguments of this paper can be summarized as follows. (1) The overlapping-generations (OG) structure provides a useful framework for the analysis of macroeconomic issues involving intertemporal allocation. (2) As a "model of money," the basic OG setup -- which excludes cash-in-advance...

The paper sets out an overlapping generations model in an open economy context. In the absence of productive capital a real consol is the vehicle for intertemporal consumption smoothing. The presence of a long term asset implies that the anticipated future path of the economy, through the term...
