We examine the long term investment problem, under stochastic interest and inflation rates and incompleteness. Four basic financial assets are available on the financial market: a money market account (the cash), a real consumption good, a financial stock index and a bond with constant maturity....

This study assesses whether the undertaken reforms in the microfinance industry in the West African Economic and Monetary Union (WAEMU) have promoted sustainability or outreach. To this purpose we use a data envelopment analysis (DEA) to measure the social efficiency on the one hand and the...

We consider an economy in which the technology exhibits nonconvexities due to fixed costs associated with production. Taking into account the incentives for investment to decrease the fixed costs, we characterize the circumstances under which an underdeveloped economy can catch up with the...

In this note, we show that the least xed point of the Bellman op- erator in a certain set can be computed by value iteration whether or not the xed point is the value function. As an application, we show one of the main results of Kamihigashi (2014a) with a simpler proof.

Discussion of Islamic private equity (PE) financing modes rarely provides detailed analytical insights into their properties: there is no rigorous analysis of their features. The current paper analyzes how and when Profit Loss Sharing (PLS) financing methods can solve asymmetric information...

The stochastic dominance ordering over probability distributions is one of the most familiar concepts in economic and financial analysis. One difficulty with stochastic dominance is that many distributions are not ranked at all, even when arbitrarily close to other distributions that are....

We investigate the diversification benefits and optimal portfolio allocation across different US asset classes. Our results from applying the principal component analysis (PCA) show that although there is an increasing trend in market integration, five major financial markets (equities, bonds,...
