In recent years numerous papers constructed or simulated financial markets at an agent level, aiming to explain the non-stationarity of price processes. All such papers agree that the heterogeneity of agents and of pricing models creates a dynamics in terms of pricing models used that explains not only the non-stationarity of price processes, but also stylised facts such as bubbles and fat tail...

This study explores how information technology, operating cost, and operational efficiency are related to each other in banking. It is well known that the adoption of information technology can reduce organizational operating cost and improve operational efficiency. However, the intuitive impacts should be evaluated in greater detail. This paper proposes a framework for measuring the performanc...

The purpose of this study was to perform an interim evaluation of the policy effect of the current reform of Japan's municipal hospitals. We focused on efficiency improvements both within hospitals and within two separate internal hospital organizations. Hospitals have two heterogeneous internal organizations: the medical examination division and administration division. The administration divi...

Data envelopment analysis (DEA) is a linear programming based methodology to determine the relative performance efficiencies of homogeneous decision making units (DMUs). In real world applications, some input and output datas do not possess crisp/fuzzy essence but they possess intuitionistic fuzzy (IF) essence. So, in this study, we develop an IF BCC (IFBCC) and an IF super efficiency BCC (IFSE...

IT landscape is the lifeline of any enterprise – managing it well thus becomes a key business imperative. This is especially true of banks and financial institutions as they function in an economic environment that is often at the brink of volatility. Changes in the market and evolving customer expectations directly impact processes, which necessitates tweaks to back-end IT applications and sof...
