The paper deals with the role of the isomorphism and homomorphism in the theory and practice of simulation. These concepts are considered as a methodological framework for models adequacy evaluation and for their suitability extent estimation to the study and improvement of economic systems,...

This paper presents an overview of some general concepts and techniques of an adequacy estimation of simulation models of the banking business processes. A proposal on specific requirements for computer simulation models to banking activity re-engineering and optimization is formulated.

This study explores critical factors for quality improvement in the Taiwanese banking industry. The study examines eight measurement dimensions. In addition, a hierarchical framework for the Taiwanese banking industry is constructed based on the eight dimensions and various sub-factors. Fuzzy...

The U.S. house price boom has been linked to an unsustainable easing of mortgage credit standards. However, standard time series models of US house prices omit credit constraints and perform poorly in the 2000's. We incorporate data on credit constraints for first time buyers into a model of US...

This paper conducts a systematic investigation of parameter instability in a small open economy DSGE model of the UK economy over the past thirty-five years. Using Bayesian analysis, we find a number of Markov-switching versions of the model provide a better fit for the UK data than a model with...

Macroeconomic forecasts are frequently produced, published, discussed and used. The formal evaluation of such forecasts has a long research history. Recently, a new angle to the evaluation of forecasts has been addressed, and in this review we analyse some recent developments from that...

In this paper, we use simulated data to investigate the power of different causality tests in a two-dimensional vector autoregressive (VAR) model. The data are presented in a non-linear environment that is modelled using a logistic smooth transition autoregressive (LSTAR) function. We use both...

Uno de los elementos claves para el régimen de metas de inflación es la correcta identificación de las presiones inflacionarias y deflacionarias a través de la brecha producto. En este trabajo brindamos una estimación de la brecha producto para la economía peruana utilizando un modelo...

It is commonly found that distributions that seem to be lognormal over a broad range change to a power-law (Pareto) distribution for the last few percentiles. The distributions of species abundance, income and wealth as well as file, city and firm sizes are examples with this structure. We...
