On the incidence of commissions in auction markets

We analyze the welfare consequences of an increase in the commissions charged by intermediaries in auction markets. Commissions are similar to taxes imposed on buyers and sellers, and standard economics suggests that both sellers and buyers are made worse off by the tax. However, we show that when the buyers' participation constraint binds and when sellers set optimal reservation prices, the level of commissions correlates to participation and reservation prices in such a way that participating buyers strictly gain from higher commissions.     

Cross-selling,switching costs and imperfect competition in British banks

This paper attempts to evaluate the competitiveness of British banking in the presence of cross-selling and switching costs during 1993–2008. It presents estimates of a model of banking behaviour that encompasses switching costs as well as cross-selling of loans and off-balance sheet transactions. The evidence from panel estimation of the model indicates that the consumer faced high switching costs in the loan market in the latter part of the sample period, as a result of weaker competitiveness in the loan market. Additionally, the weaker competitiveness in the loan market appears to facilitate the cross-selling behaviour of British banks, which helps explain the rapid growth of non-interest income during the last two decades.

Export composition and growth of selected low-income African countries: evidence from time-series data

This paper examines the hypothesis that economic growth is linked to export composition with the use of time-series data for some low-income African countries. On the basis of the regression results, the study supports the hypothesis of a positive linkage between the growth of non-fuel primary exports and growth. However, the results cast some doubt on the significance of the positive contribution of the manufactured exports sector to the growth process of the low-income African countries.     

International Pricing with Costly Consumer Arbitrage

Consumer arbitrage affects international pricing in several ways. If all consumers face the same arbitrage costs, a monopolist's profit increases with arbitrage costs, and world welfare declines with them (if output does not rise). If arbitrage costs differ across consumers, a monopolist may sell in a second country even if there is no local demand—it can use the second country to discriminate across consumers in the first country. Again, world welfare typically falls with arbitrage costs. When there is also local demand in the second country, world welfare may be increasing in arbitrage costs, even if output falls.     

A discrete and a continuous-time model based on a technical trading rule

In this article we propose a model in discrete and continuoustime that incorporates explicitly a technical trading rule inthe specification of the volatility. The proposed discrete-timemodel is an alternative to GARCH-type processes. We derive conditionsfor the covariance and strict stationarity of the discrete-timeprocess and we study the estimation and inference problems.We also analyze the conditions under which the discrete-timeprocess converges in distribution to a diffusion process. Toillustrate the proposed model and compare it with the GARCHspecification, we analyze the daily closing stock prices oftwo major U.S. companies (Microsoft and Oracle), two stock indices(DAX and NASDAQ) and two U.S. Dollar exchange rates (Euro andSterling)
