This paper examines the identifiability of the standard single-equation stochastic frontier models with uncorrelated and correlated error components giving, inter alia, mathematical content to the notion of “near-identifiability” of a statistical model. It is seen that these models are at...

This paper analyzes multifactor models in the presence of a large number of potential observable risk factors and unobservable common and group-specific pervasive factors. We show how relevant observable factors can be found from a large given set and how to determine the number of common and...

This research is devoted to analysis of efficiency estimation in presence of spatial relationships and spatial heterogeneity in data. We presented a general specification of the spatial stochastic frontier model, which includes spatial lags, spatial autoregressive disturbances and spatial...

This paper aimed at a statistical analysis of competition for tourists between regions within Baltic states (Estonia, Latvia, Lithuania) and estimation relative efficiency levels of regions. We apply a modern approach called Spatial Stochastic Frontier and corresponded to spatial modification of...

This paper is devoted to statistical analysis of spatial competition and cooperation between European airports. We propose a new multi-tier modification of spatial models, which allow estimating of spatial influence varying with the distance. Competition and cooperation effects don't diminish...

CRM has become one of the most leading business strategies in the new millennium. There is a verity of software solutions that impalement CRM principles including free and property ones. The aim of this research is to design and implement an evaluation model to help companies in choosing the...

Internal market structure analysis infers both brand attributes and consumer preferences for those attributes from preference or choice data. The authors exploit a new method for estimating probit models from panel data to infer market structures that can be displayed in few dimensions, even...

The central banks introduce and implement the monetary and financial stabilities policies, going from the accurate estimations of national macro-financial indicators such as the Gross Domestic Product (GDP). Analyzing the dependence of the GDP on the time, the central banks accurately estimate...

The study aims to calculate Egypt’s real effective exchange rate at both the bilateral and multilateral levels, estimates the effect of real cross-rate movements on trade in goods and services and on foreign direct investment, and determines the fundamental equilibrium exchange rate for...

This article tests the Black’s hypothesis in five crisis-affected Asian countries(India, Japan, Malaysia, South Korea, and Thailand). The hypothesis posits that economies face a positive relationship between output growth and output volatility. Using monthly data of the industrial production...
