The domestic taxation of petroleum products is an important source of revenue in most countries. However, there is a wide variation of tax rates on petroleum products across countries, which cannot be explained by economic theory alone. This paper surveys different considerations advanced for...

We develop a new methodology to estimate the importance of herd behavior in financial markets: we build a structural model of informational herding that can be estimated with financial transaction data. In the model, rational herding arises because of information-event uncertainty. We estimate...

The paper presents numerical simulations of various fiscal rules for oil-producing countries. Welfare implications are sensitive to the choice of the social welfare function, initial conditions, and non-oil growth prospects. The distribution of non-oil wealth is important for countries with...

Counterparty risk in the United States stemming from exposures to OTC derivatives payables (after netting) is now concentrated in five banks?Goldman Sachs, JPMorgan, Bank of America, Morgan Stanley and Citi. This note analyzes how such risks have shifted over the past year. We estimate that the...

This paper develops a theory of international currency portfolios that holds in general equilibrium, and that is therefore not subject to the criticisms directed at the portfolio balance literature of the 1980s. It shows that, under plausible assumptions about fiscal policy, the relationship...

The paper provides an alternative explanation for the ""resource curse"" based on the income effect resulting from high government current spending in resource rich economies. Using a simple life cycle framework, we show that private investment in the non-resource sector is adversely affected if...

The ongoing financial turmoil has triggered a lively debate on ways of containing systemic risk and lessening the likelihood of boom-and-bust episodes in credit markets. Particularly, it has been argued that banking regulation might attenuate procyclicality in lending standards by affecting the...

Using Chilean data, we document that for resource-rich small open economies the effects of terms of trade shocks on the wage gap (between skilled and unskilled workers) depend on factor intensities in the non-tradable sector, following the model in Galiani, Heymann, and Magud (2010). For a...
