Commodity tax harmonization and the location of industry

We study the positive implications of commodity taxation and tax harmonization under the destination and origin principles when firms are monopolistic competitors facing variable demand elasticity and segmented markets. Our emphasis is on the international location of firms in the presence of market size asymmetries and trade costs. Under the destination principle, an increase in the tax rate of a country always causes some firms to relocate to the other. This effect may be reversed under the origin principle when economic integration is deep enough. Under tax harmonization the choice of a common tax principle is irrelevant for the market outcomes and for the global tax revenues. It affects, however, the distribution of revenues between small and large countries.     

Monetary Policy in Low Income Countries in the Face of The Global Crisis: A Structural Analysis

We develop a dynamic stochastic general equilibrium model with a banking sector to analyse the impact of the financial crisis in developing countries and the role of the monetary policy response, with an application to Zambia. We view the crisis as a combination of three related shocks: a worsening in the terms of the trade, an increase in the country's risk premium and a decrease in the risk appetite of local banks. Model simulations broadly match the path of the economy during this period. We derive policy implications for central banks, and for dynamic stochastic general equilibrium modelling of monetary policy, in low‐income countries.
