In this paper we use a general equilibrium model with heterogeneous agents to assess the macroeconomic and welfare consequences in the United States of alternative fiscal policies over the medium-term. We find that failing to address the fiscal imbalances associated with current federal fiscal...

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...

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...

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...

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...

In short, yes. I use a multi-region integrated assessment model with fuel-specific endogenous technical change to examine the impact of Europe and China reducing emissions to zero by mid-century. Without international technological diffusion this is insufficient to avoid catastrophic climate...

This paper explores the role of trade instruments in globally efficient climate policies, focusing on the central issue of whether some form of border tax adjustment (BTA) is warranted when carbon prices differ internationally. It shows that tariff policy has a role in easing cross-country...
