This paper addresses estimation and decomposition of productivity change, which is mostly identified as technical change under constant (unitary) returns to scale (CRS). If the CRS assumption is not made, productivity change is decomposed into technical change and scale effects.Furthermore, if...

This paper deals with modeling firm-specific technical change (TC), and technological biases (inputs and scale) in estimating total factor productivity (TFP) growth. Several dual parametric econometric models are used for this purpose. We examine robustness of TFP growth and TC among competing...

Although most production activities involve multiple outputs, econometric models of production or cost functions normally involve only one single homogeneous output. The aim of this paper is to test the hypothesis that a multiproduct specification is superior to a model with a single homogenous...

If the output market is perfectly competitive and the firm’s production function is not concave, an increase in the output price may lead to an explosive increase in firm’s profits at some point. We explore the properties of this point, called a threshold price. We derive the formula for the...

Using the US banking industry data during 1991-2000, this paper carries out a cluster analysis to segment banks into distinct strategic groups in terms of their product mix and allocation of inputs. We then investigate the production technology and cost structures for banks in each strategic...

We use a dynamic game model of a two-country monetary union to study the impacts of an exogenous fall in aggregate demand, the resulting increase in public debt, and the consequences of a sovereign debt haircut for a member country or bloc of the union. Two different scenarios for such a haircut...

This paper develops a novel methodology to study robust stability properties of Nash equilibrium points in dynamic games. Small-gain techniques in modern mathematical control theory are used for the first time to derive conditions guaranteeing uniqueness and global asymptotic stability of Nash...

Der Einzelhandel in der Bandbreite seiner heutigen Erscheinungsformen hat auf der Angebotsseite sowie auf der Nachfrageseite in den zurückliegenden Jahrzehnten einen gravierenden Wandel vollzogen. Dabei ist eine generalisierende Beurteilung sehr schwierig, liegen doch zwischen SB-Warenhäusern,...
