DOES MONOPOLISTIC COMPETITION EXIST IN THE MENA REGION? EVIDENCE FROM THE BANKING SECTOR

The goal of this paper is to empirically assess the level of banking competition in selected Middle East and Northern African (MENA) countries. The analysis employs the estimation of a non‐structural indicator (H‐statistic) introduced by Panzar and Rosse and draws upon a panel dataset of eight MENA countries (Algeria, Egypt, Israel, Jordan, Morocco, Oman, Saudi Arabia, and United Arab Emirates) over the period 1997–2012. The empirical findings are robust towards three different panel data econometric techniques (Ordinary Least Squares, Pooled Generalized Least Squares with Fixed Effects, and Generalized Method of Moments) and consistent with other similar studies, providing sufficient evidence in favour of a banking monopolistic competition regime. Furthermore, the estimation of three other alternative measures of competition (Lerner index, adjusted Lerner index, and conduct parameter) provides similar results, revealing that the banking sector in the MENA region is characterized by a low level of Significant Market Power (SMP). Overall, the analysis shows that, despite similarities in the process of financial regulatory reforms undertaken in the eight MENA countries, the observed competition levels of banks vary substantially, with Algeria and Morocco consistently outperforming the rest of the region.     

Can we reject linearity in an HAR-RV model for the S&P 500? Insights from a nonparametric HAR-RV

This article tests the linearity assumption underlying the popular heterogeneous autoregressive model for realized volatility (HAR-RV). We implement a consistent model specification test that is robust to both distributional and model misspecification. We find that, using a nonparametric HAR-RV (NPHAR-RV), we are unable to reject the null of linearity.     

Dynamic effects of trade openness on financial development

This paper employs the Pooled Mean Group (PMG) approach of Pesaran et al. (1999) to study the dynamic effects of trade openness on financial development. The advantage of the PMG estimator over other dynamic panel econometric techniques is that it allows short-run coefficients, speeds of adjustment and error variances to vary across countries, with cross-country homogeneity restrictions only on long-run parameters. Our results spanning 88 countries over 1960–2005 show that a positive long-run relationship between trade openness and financial development coexists with a negative short-run relationship. But when splitting the data into different income or inflation groups, this finding is observed only in relatively low-income countries or high-inflation economies.     

The impact of ECB and FED announcements on the Euro interest rates

We investigate the impact of news in the ECB and FED monetary policy announcements on daily changes in Euro interest rates. We document significant impacts of ECB announcements throughout the period but only until mid 2004 of FED announcements.     

Credit Losses in Australasian Banking

We analyse the determinants of bank credit losses in Australasia. Despite sizeable credit losses over the past two decades, ours is the first systematic study to do so. Analysis is based on a comprehensive dataset retrieved from original financial reports of 32 Australasian banks (1980–2005). Credit losses rise when the macro economy is weak. Asset markets, particularly the equity market, are also important. Larger banks provide more for credit losses while banks with high cost-income-ratios show greater loan loss provisions. Strong loan growth translates into significantly higher credit losses with a lag of 2–4 years. Finally, the results show strong evidence of income smoothing activities by banks.     

Treasury auctions: Uniform or discriminatory?

There has been much discussion of the relative merits of selling government bonds using a uniform-price auction rather than the traditional discriminatory-price auction. Arguments in favor of the former have won the day in respect of the newly instituted auctions of index-linked bonds in the USA and UK. This short paper assesses the evidence and concludes that the advantages of uniform-price auctions have been oversold. Received: 28 May 1999 / Accepted: 27 September 1999
