This paper studies the factor of competitive conditions of conventional and Islamic banks operating in the same market in the MENA region. We determine the level of competitiveness between the two types of banks by using the PR-H statistic of Panzar and Ross (1987) and the Lerner index. Our...

In this note, we present a wealth model of a two-country economy where ffnancial assets and goods are traded. We consider the case where the agents are risk neutral, a very common assumption in ffnance in order to have explicit solutions for prices, and in particular in international ffnance for...

The purpose of this paper is to analyze the gap risk of dynamic portfo- lio insurance strategies which generalize the "Constant Proportion Port- folio Insurance " (CPPI) method by allowing the multiple to vary. We illustrate our theoretical results for conditional CPPI strategies indexed on...

This paper examines the strategy in resource allocation of a firm which must choose between several production functions. These latter ones can differ by their respective initial investment amounts, input costs, output levels and prices...Such management problem is often posed when input values...

The pro-competitive effects of forward contracts in electricity market can- not be regarded alone without examining the market structure. In this paper, we show that under retail competition, spot market demand uncertainty and risk aversion, partially or fully integrated electricity generators...

Forecasting the density of returns is useful for many purposes in finance, such as risk manage- ment activities, portfolio choice or derivative security pricing. Existing methods to forecast the den- sity of returns either use prices of the asset of interest or option prices on this same asset....

In this paper, we first provide empirical evidence of the existence of intraday jumps in the crude oil price series. We then show that these jumps, in conjunction with realized volatility measures, are important in modeling the convenience yield over the 2001-2010 period. Our empirical results...

This article assesses the impact of real energy prices on the consumption of different energy sources in Tunisia. We estimate the short-run and long-run energy demand elasticities over the period 1980-2004, where energy demand is specified by a simple partial adjustment model. Our results show...

In this paper, we review the extant mathematical and environmental economics literatures on the stochastic properties of CO2 emission allowance futures prices. We explain the main findings arising from this literature from both continuous- and jump-diffusion models. Based on the Activity...
