In this paper we conduct a quantitative analysis of a number of stylized educational loan systems. We develop a stochastic general equilibrium model of a closed economy with a competitive firm sector and a government that levies taxes and administers educational loans. Individuals are...

We study the effects on the macroeconomic equilibrium, the wealth distribution, and welfare of adverse selection in private annuity markets in a closed economy inhabited by overlapping generations of heterogeneous agents who are distinguished by their health status. If an agent’s health type...

We study the implications of adverse selection in annuity markets in a general-equilibrium model of the closed economy. Agents differ in their health type and invest their assets in the annuity market. Without informational asymmetries each agent would obtain an actuarially fair insurance. If...

This exercise and solutions manual accompanies Foundations of Modern Macroeconomics, Second Edition Foundations of Modern Macroeconomics deals with all the major topics, summarizes the important approaches, and gives students a coherent angle on all aspects of macroeconomic thought. Each chapter...

How do population ageing shocks affect the long-run macroeconomic performance of an economy? To answer this question we build a general equilibrium overlapping generations model of a closed economy featuring endogenous factor prices. Finitely-lived individuals are endowed with perfect foresight...

We construct a tractable discrete-time overlapping generations model of a closed economy and use it to study government redistribution of accidental bequests and private annuities in general equilibrium. Individuals face longevity risk as there is a positive probability of passing away before...

We study a closed economy featuring heterogeneous agents and exhibiting endogenous economic growth due to interfirm external effects. Individual agents differ in terms of their mortality profile. At birth, nature assigns a health status to each agent. Health type is private information and...

It takes a woman and a man to make a baby. This observation suggests that for a birth to take place, both parents should agree that they are better off with another child. In this paper, we first show empirically that agreement between the parents indeed makes a birth much more likely. We then...

The economic theory of fertility choice builds predominantly on the unitary model of the household, in which there is a single household utility function and potential intra-household disagreement is abstracted from. Empirical evidence suggests, however, that many (potential) mothers and fathers...

In this paper we argue that a capital income tax is an effective tool for redistribution and insurance even when progressive labor income taxes are available to the policy maker. To make this point we construct a large scale Overlapping Generations Model with uninsurable income risk, show that...
