All over the world, banks have been undergoing crisis, but the Nigerian experience has been hazardous to the country’s financial sector stability. Against this scenery, this paper investigates some cost efficiency correlates of a set of fifteen deposit money banks in Nigeria over the period...

In this paper we present a reformulation of a lemma due to Lippman and McCall - initially formulated a unique random variable - to be applied to the case of several random variables, and we illustrate its use in the theory of the firm under uncertainty. We have performed this on a recent model...

The goal of this study is to get a premium calculation principle, for the life insurance business, based on a coherent risk measure (Wang, 1995) in the form of power, called \Proportional Hazards (PH) Transforms" to justify the recommendation of Solvency II to reduce the effect of the mortality...

The purpose of this study is to measure the relative efficiency of banks in Jordan using DEA. Also, it investigated the determinants of such efficiency, in terms of bank size and capitalization. The duration of the measured performance of this sector is (2005-2008). The results indicate that...

In October 2002, a substitution reform was introduced in the Swedish pharmaceuticals market. In this paper, the effects of increased price competition due to the reform on the entry of new pharmaceutical products were studied. The results show that the reform did affect the entry behavior of...

This paper's field evidence is: (1) in reality a major exchange rate change devastates an economy, i.e. the widespread academic faith that exchange rate changes are either beneficial or harmless is a false faith that contributes to needless world-wide economic havoc; (2) the 1982-85 exchange rate...

Using the maximum likelihood method, in order to estimate Half-Normal stochastic frontier production models, entails several practical di±culties that, perhaps, have not been su±ciently emphasised. In employing FRONTIER software, we analyse the case in which the estimation obtained suggests...

Grey system theory can powerfully deal with incomplete and uncertain information. In this paper, we introduced an improved grey GM(1,1) model that integrates residual modification with Markov chain model. By this model, we improved the forecast accuracy of original grey forecast model and...

The paper intends to measure the daily Value-at-Risk (VaR) for Rial-Euro exchange rate fluctuations risk. Since in this case we deal with a single risk factor, so we will not use the Monte Carlo simulation method to measure the VaR and we will only use the parametric and historical simulation...

Insurance companies have to estimate reserves and provisions to cover the payment of either unreported claims or unsettled claims. In this paper, we apply the Chain-Ladder method to obtain a point estimate of reserves, and then we use the bootstrap technique to estimate the margin of error and...
