In this paper we study how a benevolent government that cannot commit to future policy should trade off the costs and benefits of public expenditure. We characterize and solve for Markov-perfect equilibria of the dynamic game between successive governments. The characterization consists of an...

In an economy with distortionary taxes on labor, can subsidies on day care, financed by an increase in taxes, raise welfare by encouraging women with small children to work? We show, within a heterogeneous-agent life-cycle framework, that the Ramsey optimal policy consists in equalizing...

Barriers to labor mobility across countries coexist with substantial differences in living standards largely attributable to productivity differences. A growth model with endogenous labor movements is used to assess the effects on output, capital accumulation and welfare of removing barriers to...

In this paper, we document some features of the distribution of income, consumption and wealth in Canada using survey data from many different sources. We find that wage and income inequality has increased substantially over the last 30 years, but that much of this rise was offset by the tax and...

Several approaches to finding the second-order approximation to a dynamic model have been proposed recently. This paper differs from the existing literature in that it makes use of the Magnus and Neudecker (1999) definition of the Hessian matrix. The key result is a linear system of equations...

Migration restrictions are pervasive and severe. Their worldwide enactment starting in the 1920's constituted a fundamental policy shift for a number of countries and for the world as whole. Yet, very little is currently known about the quantitative consequences of these barriers to labor...

Sweden's distribution of disposable income is very even, with a Gini coefficient of just 0.31. Yet, the wealth distribution is extremely unequal, with a Gini coefficient of 0.79. Moreover, Swedish wealth inequality is to a very large extent driven by the large fraction of households with zero or...

Optimal tax policies in dynamic models have unappealing features. In particular, optimal tax reform typically involves a large initial accumulation of government assets which is responsible for a large part of the welfare gains from optimal tax reform. In this paper, we investigate the...
