We examine how allowing individuals to emigrate to pay lower taxes changes the optimal nonlinear income tax scheme in a Mirrleesian economy. An individual emigrates if his domestic utility is less than his utility abroad, net of migration costs – utilities and costs both depending on...

Using the Mirrlees optimal income tax model, with no income effects on labour supply, this article shows that the discrete population approach provides new insights into the characterization of the optimal tax system, which complements the previous findings. The analysis is based on the...

We examine how allowing individuals to emigrate to pay lower taxes abroad changes the optimal non-linear income tax scheme in a Mirrleesian economy. An individual emigrates if his domestic utility is less than his utility abroad net of migration costs, utilities and costs both depending on...

While the literature on how intergovernmental grants affect the budget of receiving jurisdictions is numerous, the very few studies that explicitly deal with likely endogeneity problems focus on grants targeted towards specific sectors or to specific type of recipients. The results from these...

Staggered prices are a fundamental building block of New Keynesian dynamic stochastic general equilibrium models. In the standard model, prices are uniformly staggered but recent empirical evidence suggest that deviations from uniform staggering are common, This paper analyzes how...

Financial intermediation and bank spreads are important elements in the analysis of business cycle transmission and monetary policy. We present a simple framework that introduces lending relationships, a relevant feature of financial intermediation that has been so far neglected in the monetary...

We use a rapid introduction of an unconditional cash grant (child support) in South Africa to estimate the marginal propensity to consume and earn out of a permanent change in unearned income. We find that the marginal propensity to earn is about to -0.25 for single-adult households, and...

The paper develops an equilibrium search and matching model where two-person families as well as singles participate in the labor market. We show that equilibrium entails wage dispersion among equally productive risk-averse workers. Marital status as well as spousal labor market status matter...

I study the size and sources of the monetary return to college achievement as measured by cumulative Grade Point Average (GPA). I first present evidence that the return to achievement is large and statistically significant. I find, however, that this masks variation in the return across...

The paper extends Ng’s (1987) model of optimal taxation of diamond goods — goods that are valued solely for their costliness. We extend his findings by analyzing how other goods should be taxed in the presence of pure diamond goods; modified Ramsey rules are derived in a basic single-type...
