This paper explores the trade-off between incentive effects and administrative costs associated with the implementation of various environmental tax instruments, with special reference to carbon taxes. In a simple model, we show under what conditions it is optimal to use input rather than...

This paper attempts to estimate the size and distribution of tax evasion in rich countries. We combine random audits--the key source used to study tax evasion so far--with new micro-data leaked from large offshore financial institutions--HSBC Switzerland ("Swiss leaks") and Mossack Fonseca...

It concludes by constructing a simple model in which knowledge flows slowly across national borders but moves easily within borders. We show there is a leadership-followership equilibrium, in which some countries are leaders, others are followers. Contrary to Solow's analysis, there need not be...

Because of their more limited inequality and more comprehensive social welfare systems, many perceive average welfare to be higher in Scandinavian societies than in the United States. Why then does the United States not adopt Scandinavian-style institutions? More generally, in an interdependent...

This paper investigates the design of an exchange rate policy for an economy where the domestic capital market is segmented from the global financial market, producers rely on credit to finance working capital needs, and the labor market is characterized by nominal contracts. We show that the...

In his seminal 1960 article Robert Mundell proposed a model of balance-of-payments crises in which confidence in the continuation of a currency peg depended on the observed holdings of central bank foreign reserves. We examine the implications of a reformulation of this view from the perspective...

This paper shows that the risk of devaluation can be an important factor accounting for the stylized facts of exchange-rate-based stabilizations. This conclusion follows from studying the quantitative implications of a two-sector equilibrium business cycle model of a small open economy...

This paper examines the international experiences with four basic types of monetary policy regimes: 1) exchange-rate targeting, 2) monetary targeting, 3) inflation targeting, and 4) monetary policy with an implicit but not an explicit nominal anchor. The basic theme that emerges from this...

The analysis focuses on the government budget constraint and the resolution of inconsistent implications of different policy instruments under that constraint. We show how, under floating exchange rates, external shocks or internal structural reforms may cause jumps in inflation and the exchange...
