Supplier selection problem usually is very complicated, because variety of uncontrollable and unpredictable factors affect on evaluation and decision-making process. Various decision making approaches have been proposed to tackle the problem as part of a general tendering process, particularly...

The adjustment of the information obtained from household surveys to make the figures compatible with National Accounts is a non-standard and potentially questionable practice given that it alters the structure of income distribution. This paper analyzes the sensitivity of inequality and poverty...

Genetic algorithms (GAs) are appropriate when investors have the objective of obtaining mean.variance (VaR) efficient frontier as minimising VaR leads to non.convex and non.differential risk.return optimisation problems. However GAs are a time.consuming optimisation technique. In this paper, we...

This article provides a tool to study over time the distributions of income in a population, regardless the irregular distribution of data. We even approach Lorenz curves at the times when we lack the required data. Finally we apply the present technique to a European country where inequalities...

This paper assesses a performance evaluation framework for wealth management (WM) banks. We propose a method that combines the analytic hierarchy process (AHP) with the assurance region (AR) model of data envelopment analysis (DEA) to enable a consensus decision. We also present several...

High technology exports (HTX) are considered as an important factor for sustainable economic growth for a country. One of the most important prerequisite to high tech manufacturing and export is technology ownership. Technology ownership can be gained through technology transfer by the way of...

This paper applies a four-stage data envelopment analysis (DEA) approach proposed by Fried et al. (1999) to measure the operational environment-adjusted efficiency of sixty mutual funds in Taiwan from 2006 to 2010. We adopt the approach for adjusting negative output as suggested by Lovell and...

Passive investment strategies basically aim to replicate an underlying benchmark. Thereby, the management usually selects a subset of stocks being employed in the optimization procedure. Apart from the optimization procedure, the stock selection approach determines the stock portfolios's...

Even though a random walk process is from a statistical point of view not predictable, some movements can be correlated with specific events concerning other variables. Then, predictable patterns may arise being dependent on this joint event. There is evidence given that equity price busts being...
