We argue that labor mobility does not lead to a ''race to the bottom,'' where countries drastically cut redistributive transfers in order to attract skilled workers. The basis of our argument is that these cuts are not credible policies. We propose a two country model where competition for...

Does worker mobility undermine governments ability to redistribute income? This paper analyzes the experience of US states in the recent decades. We build a tractable model where both migration decisions and redistribution policies are endogenous. We calibrate the model to match skill premium...

We ask whether worker mobility has undermined the ability of U.S. states to redistribute income. We build a tractable model where both migration decisions and redistribution policies are jointly determined. Our model features a large number of heterogeneous regions and skilled and unskilled...

We analyze the joint determination of income redistribution and migration flows across fiscally independent regions. In our model, regional governments lack commitment so their policy announcements must be credible, and redistribution between skilled and unskilled workers is bounded by...

I show that multiple equilibria are a general property of economies under full monetary policy discretion. Three simple conditions are sufficient to rule out, generically, a unique equilibrium in a static economy. The key departure from Barro and Gordon (1983) is to consider bounded welfare...

Lack of commitment in monetary policy leads to the well known Barro-Gordon inflation bias. In this paper, we argue that two phenomena associated with the time inconsistency problem have been overlooked in the exchange rate debate. We show that, absent commitment, independent monetary policy can...

We provide a tractable model to study monetary policy under discretion. We focus on Markov equilibria. For all parametrizations with an equilibrium inflation rate around 2%, there is a second equilibrium with an inflation rate just above 10%. Thus the model can simultaneously account for the low...

We provide a tractable model to study monetary policy under discretion. We restrict our analysis to Markov equilibria. We find that for all parametrizations with an equilibrium inflation rate of about 2 percent, there is a second equilibrium with an inflation rate just above 10 percent. Thus,...

The Barro-Gordon inflation bias has provided the most influential argument for fixed exchange rate regimes. However, with low inflation rates now widespread, credibility concerns seem no longer relevant. Why give up independent monetary policy to contain an inflation bias that is already under...

A number of stylized facts have been documented about the extensive margin of trade---which firms export, and how many products they send to how many destinations. We argue that the sparse nature of trade data is crucial to understanding these stylized facts. Typically the number of...
