We study the dynamic Ramsey problem of finding optimal public debt and linear taxes on capital and labor income within a tractable infinite horizon model with incomplete markets. With zero public expenditure and debt, it is optimal to tax the risky labor income and subsidize capital, while a...

We consider an economy where individuals face uninsurable risks to their human capital accumulation, and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

According to the “Saving Glut hypothesis”, global imbalances are caused by inefficiently high level of precautionary savings in financially underdeveloped regions, where agents have limited opportunity to diversify idiosyncratic risk. This paper generalizes the approach by modeling...

This paper examines consumption and savings dynamics in a standard model of incomplete markets. Existence of equilibrium requires the imposition of exogenous debt limits but these are often ignored because of the computational difficulties that arise in models with occasionally binding...

Using vector autoregressions on U.S. time series, we find that technology shocks induce an ‘S’- shaped cross-correlation function for the trade balance and the terms of trade (S-curve). In calibrating a prototypical international business cycle model to match the S-curve under complete and...

We use a 12-dimensional VAR to examine the dynamic effects on the labor market of four structural technology and policy shocks. For each shock, we examine the dynamic e®ects on the labor market, the importance of the shock for labor market volatility, and the comovement between labor market...

We provide empirical evidence on the effects of tax liability changes in the United States. We make a distinction between “surprise” and “anticipated” tax shocks. Surprise tax cuts give rise to a large boom in the economy. Anticipated tax liability tax cuts are instead associated with a...

This paper explores on a yearly panel of nineteen OECD countries from 1970-2001 the effects of fiscal policy on private consumption in recessions and expansions. In the presence of binding liquidity constraints on households, fiscal policy is more e¤ective in boosting private consumption in...

This paper quantifies the effects of credit spread and income shocks on aggregate house prices and households’ welfare. We address this issue within a stochastic dynamic general equilibrium model with heterogeneous households and occasionally binding collateral constraints. Credit spread...

While it is recognized that the family is primarily an institution for risk sharing, little is known about the quantitative effects of this informal source of insurance on savings and labor supply. In this paper, we present a model where workers (females and males) are subject to idiosyncratic...
