Four options to make the social security sustainable under the coming demographic shift are presented; increase payroll taxes by 6 percentage points, reduce replacement rates by one-third, raise the normal retirement age to 73, or means-test the benefits and reduce them in income. The paper...

This paper studies lifetime aggregate labor supply with endogenous workweek length. Such a theory is needed to evaluate various government policies. A key feature of our model is a nonlinear mapping from hours worked to labor services. This gives rise to an endogenous workweek that can differ...

This article studies the determinants of the labor force participation of the elderly and investigates the factors that may account for the increase in retirement in the second half of the last century. We develop a life-cycle general equilibrium model with endogenous retirement that embeds...

Often an increase in the minimum wage is accompanied by a reduction in the capital tax. This paper analyzes the effects of interactions between the minimum wage and the capital tax in the general equilibrium framework. The analysis is conducted in an inter-temporal search model in which 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...

What determines the relationship between pollution and growth? Are the forces that explain the behavior over time of these quantities potentially useful to understand more generally the relationship between policies and growth? In this paper we make a first attempt to analyze the equilibrium...

The paper estimates a job search model with savings on Danish microdata that include observations on wealth and wages. Controlling for extensive observed and unobserved worker characteristics heterogeneity, the estimation relates observed unemployment spells to the model implied hazard rate for...

This paper quantifies the effects of social security on capital accumulation and wealth distribution in a life-cycle framework with altruistic individuals. The main findings of this paper are that the current U.S. social security system has a significant impact on capital accumulation and wealth...

The Modified Golden Rule, which relates the rate of return on capital and the growth rate of the capital stock along long-run growth paths that maximize the utility of a representative infinitively-lived consumer, is invariant to the introduction of convex capital adjustment costs. Therefore,...

The business cycle accounting "wedge" methodology is used to identify the mechanisms driving the rapid growth of Hong Kong, Singapore, South Korea, and Taiwan since 1966. Analysis with a neoclassical growth model reveals that growth in these economies has been sustained by different mechanisms...
