We investigate the causal structure of financial systems by accounting for contemporaneous relationships. To identify structural parameters, we introduce a novel non-parametric approach that exploits the fact that most financial data empirically exhibit heteroskedasticity. The identification...

The authors examine how the use of extreme value theory yields collateral requirements that are robust to extreme fluctuations in the market price of the asset used as collateral. In particular, they study the risk and cost attributes of market risk measures by constructing a risk-cost frontier...

We evaluated the execution of the operational programs (OPs) committed to encouraging the adoption of information and communication technologies (ICTs) in small and medium-sized enterprises (SMEs). To achieve this goal, we employed a novel three-stage weighted Russel directional distance (WRDD)...

Foundational to the discipline of management is the idea that organizational decisions are a function of expected outcomes; hence, the customary empirical approach to employ multivariate techniques that regress performance outcome variables on discrete measures of organizational choices (e.g.,...

In this article we test the relationship between per capita income differential and exchange rate differential between two different economic background countries. Recent researches have been done on the testing of international Fisher effect, Interest rate, GDP growth rate and purchasing power...

Since the industry standard approach to judge on the effectiveness of promotion is based on the impact on expected sales it cannot grasp other impacts in the distribution of future sales. Since retailers operate with very high strategic service level targets (e.g. 98%) high quantiles of the...

In the late 1990s, as economists looked back the development period in Africa since 1970s, they put forward the notion “African growth tragedy” , meaning that Africa's poor growth and resulting low income is associated with low schooling, political instability, underdeveloped financial...
