The purpose of this paper is to provide an in-depth analysis, using both financial ratio analysis and data envelopment analysis (DEA), of a consistent sample of Islamic and conventional banks located in the GCC region over the period 2004 to 2007. Results from the financial ratio analysis...

Several recent studies advocate the use of nonparametric estimators of daily price vari-ability that exploit intraday information. This paper compares four such estimators, realisedvolatility, realised range, realised power variation and realised bipower variation, by examiningtheir in-sample...

Tautological structures bring clarity to arguments in macroeconomics: familiar structures relate to the circulation of money, the circular flow of real income, and the balance of international payments. Less familiar is a structure incorporating all aspects of macroeconomic policy interventions....

The detection of explosive behavior in house prices and the implementation of early warning diagnosis tests are of great importance for policy-making. This paper applies the GSADF test developed by Phillips et al. (2012) and Phillips et al. (2013), a novel procedure for testing, detection and...

Much of the recent discussion on the impact of immigrants on the host economies relate to the costs they impose on the host country’s public finances and the labour market rather than their contribution to the growth of incomes, technology and trade. This paper analyses the contribution...

This paper shows that electoral incentives affect the occurrence of trade disputes. Focusing on WTO disputes filed by the United States during the 1995-2012 period, we show that U.S. presidents are more likely to initiate a dispute in the year preceding their re-election date. Moreover, disputes...

We estimate a variety of models to evaluate costs in US higher education institutions. A novel feature of our approach involves the estimation of latent class and random parameter stochastic frontier models of the multiproduct cost function. This allows us fully to accommodate both the...

We extend the analysis of price caps in oligopoly markets to allow for sunk entry costs and endogenous entry. In the case of deterministic demand and constant marginal cost, reducing a price cap yields increased total output, consumer welfare, and total welfare; results consistent with those for...

High unemployment continues to bedevil Poland, although the national picture masks striking spatial differences that this paper seeks to explain using a panel data set for the country's NUTS 4 level powiats. Given the economy's somewhat peculiar configuration throughout its communist epoch,...
