This paper investigates the linkages between oil and growth in Congo, where there appears to be no evidence of direct spillover effects. The empirical results suggest however that political instability has a negative effect on non-oil growth, and that the presence of oil could have fueled...

Why do prices in Spain's regions fail to converge? The prime suspects for this puzzling result are differences in regional barriers to entry in retail distribution. This paper develops a Cournot-Nash model of imperfect competition to illustrate the effect of barriers on prices. A unique data...

We provide empirical evidence that deviations from uncovered interest rate parity (UIP) display significant nonlinearities, consistent with theories based on transaction costs or limits to speculation. This evidence suggests that the forward bias documented in the literature may be less...

We apply the fundamentals equilibrium exchange rate (FEER) approach and the Johansen cointegration methodology to investigate the behavior of the real effective exchange rates of the two monetary unions of the CFA franc zone (CEMAC and WAEMU) vis-à-vis their long-run equilibrium paths. For both...

This paper discusses the dual interpretation of the Jeffreys–Lindley’s paradox associated with Bayesian posterior probabilities and Bayes factors, both as a differentiation between frequentist and Bayesian statistics and as a pointer to the difficulty of using improper priors while testing....

There has been little systematic empirical study on the relationship between remittances and growth. This paper attempts to examine this relationship. Using a newly constructed crosscountry of data series for remittances covering a large sample of developing countries, we relate the interaction...

This paper takes stock of revenue forecasting practices in low-income countries, and provides a comprehensive and condensed account of the revenue forecasting process. Based on a new dataset on 34 low-income countries, it catalogues forecasting practices and procedures from inception until...

This Selected Issues paper analyzes the underlying sources of growth in Uganda, suggesting that the contribution to growth from total factor productivity has been minor, while the high population growth poses a significant challenge to sustain a rapid improvement in living standards. The paper...
