In this article, we study the welfare effects of unfunded social security in a general equilibrium model populated with overlapping generations of altruistic individuals that differ in lifetime expectancy and earnings ability. Contrary to previous research, our results indicate that steady-state...

This paper examines the growth experience of a cross section of U.S. firms, and relates these findings to the financial returns of these firms

We use balance sheet and National Income and Products Accounts (NIPA) data to calibrate factor shares in a model with three factors (land, labor, and capital) and three sectors (business, household, and government). These estimates are used in an overlapping generations model with land to study...

The U.S. national saving rate has been declining since the 1960s while the share of consumption in output has been increasing. We explore if a standard growth model can explain the secular movements observed in this time period. Our quantitative findings indicate that the standard neoclassical...

In this paper, we modify the standard neoclassical model by incorporating financial intermediation in order to deliver returns consistent with the observation that capital primarily flows to middle income countries. We build a static contracting framework where costly intermediation together...

Japanese and U.S. saving rates have been significantly different over the last forty years. Can a standard growth model explain this difference? The answer is yes. Our results indicate that both an infinite horizon, complete markets setup and an overlapping generations model with incomplete...

The potential welfare benefits of unemployment insurance, along with the optimal replacement ratio, are studied using a quantitative dynamic general equilibrium model. To provide a role for unemployment insurance, agents in the authors' economy face exogenous idiosyncratic employment shocks and...

In this paper we examine the role of social security in an economy populated by overlapping generations of individuals with time-inconsistent preferences who face mortality risk, individual income risk, and borrowing constraints. We find that unfunded social security lowers the capital stock,...
