It is argued that taxation causes three kinds of deadweight losses and two types of direct costs. The deadweight losses arise from substitution, evasion, and avoidance activities while the direct costs are administrative and compliance costs. Some of these social costs tend to be discontinuous...

This paper analyzes the erosion of fiscal revenue by inflation resulting from the issuance of money. The empirical evidence for a number of developing countries supports the well-known hypothesis that an increase in inflation will result in a fall in real fiscal revenue because of collection...

Macroeconomic costs of conflict are generally very large, with GDP per capita about 28 percent lower ten years after conflict onset. This is overwhelmingly driven by private consumption, which falls by 25 percent ten years after conflict onset. Conflict is also associated with dramatic declines...

We study the robustness of the Lerner symmetry result in an open economy New Keynesian model with price rigidities. While the Lerner symmetry result of no real effects of a combined import tariff and export subsidy holds up approximately for a number of alternative assumptions, we obtain...

This paper proposes a measure of the welfare cost of volatitliy derived from an endogenous growth model (AK) under uncertainty extended to the case of a recursive utility function which disentangles risk aversion from intertemporal elasticity of substitution. It encompasses a direct welfare cost...

The paper studies determinants and consequences of sharp reductions in current account imbalances (reversals) in low- and middle-income countries. It poses two questions: what triggers reversals, and what factors explain how costly reversals are? It finds that both domestic variables, such as...

While a standard academic presumption has been that wage indexation reduces the cost of disinflation, policymakers generally contend that wage indexing makes disinflation more difficult. To shed light on these views, this paper reexamines the effects of wage indexing on the output loss caused by...

Fiscal policy is a key tool for achieving distributional objectives in advanced economies. This paper embeds the discussion of fiscal redistribution within the standard social welfare framework, which lends itself to a transparent and practical evaluation of the extent and determinants of fiscal...
