In an interconnected world, national economic policies regularly lead to large international spillover effects, which frequently trigger calls for international policy cooperation. However, the premise of successful cooperation is that there is a Pareto inefficiency, id est if there is scope to...

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...

In March 2018, representatives of member countries of the African Union signed the African Continental Free Trade Area (AfCFTA) agreement. This agreement provides a framework for trade liberalization in goods and services and is expected to eventually cover all African countries. Using a...

This paper studies the potential long-term effects of three illustrative scenarios using a multi-sector computable general equilibrium (CGE) trade model calibrated to 165 countries. The first scenario estimates effects from potential U.S. auto tariffs. The second analyzes a 'transactional deal'...

This paper develops a dynamic general equilibrium model to assess the effects of temporary business tax cuts. First, the analysis extends the Ricardian equivalence result to an environment with production and establishes that a temporary tax cut financed by a future tax-increase has no real...

The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

This paper estimates the neutral interest rate in the Kyrgyz Republic using a range of methodologies. Results indicate that the real neutral rate is about 4 percent based on an average of models and 3.7 percent based on a Quarterly Projection Model. This is higher than in many emerging markets...

This paper provides a quantitative evaluation of the intracohort redistributive elements of the U.S. social security system in the context of a computable general equilibrium model. It determines how the well-being of individuals that differ by gender, race, and education is affected by the...

The paper presents a DGE model designed as a core projection tool to support monetary policy in inflation-targeting (IT) emerging market economies. The paper uses a particularly simple and flexible general equilibrium model structure that can be amended to account for various phenomena that...

This paper constructs a general equilibrium model with monopolistically competitive firms and endogenous markups where government spending consists of both consumption and investment goods. It is shown that when markups are countercyclical, increases in the share of investment goods in aggregate...
