Over the past two years, the IMF staff has been developing a new multicountry macroeconomic model called the Global Economy Model (GEM). This paper explains why such a model is needed, how GEM differs from its predecessor model, and how the new features of the model can improve the IMF’s...

Exchange rate pass-through in a set of euro area prices along the pricing chain is examined. Using a vector autoregression (VAR) approach, the empirics analyze the joint time-series behavior of the euro exchange rate and a system of euro-area prices in response to an exchange rate shock. The...

This paper uses a partial equilibrium framework to compare the welfare consequences of different methods of quota administration relative to free trade under imperfect competition. It shows that a country importing a good from foreign duopolists may improve its welfare by setting a quota at the...

The paper models export taxation of a primary commodity in a large country under two hypotheses about the structure of its export market. The first is perfect competition among exporters, where there is an indefinite number of buyers of the local product and at least a partial pass-through of...

There is a concern that the state-dominated, inefficient, and fragile banking systems in many low-income countries, especially in sub-Saharan Africa, are a major hindrance to economic growth. This paper systematically analyzes the impact of the far-reaching banking sector reforms undertaken in...

This paper uses a variant of the IMF's Global Economy Model (GEM) to estimate the macroeconomic effects of Yemen's full accession into the Gulf Cooperation Council (GCC). After calibrating the model to Yemen and the GCC countries, several simulations were carried out to estimate the potential...

This paper presents empirical evidence on the impact of competition on firm productivity. Using firm-level observations from the World Bank Enterprise Survey database, we find a positive and robust causal relationship between our proxies for competition and our measures of productivity. We also...

This paper presents a theoretical framework for analyzing pricing structures in debit card schemes featuring cardholders, retailers, their respective banks, and a network routing switch. The network routing switch controls the electronic debit card network and is jointly owned by the banks. In...
