This paper uses a new measure of bank service output to estimate various specifications of production and cost functions for Bank Holding Companies (BHCs) over the period 1986 to 1999. The new output series is a true flow measure of bank service value added, and it follows from a unified model...

This study proposes a "Flexible Cost Model" (FCM) for settings in which firms may be unable or unwilling to optimally manage their cost structures. FCM, which nests a wide range of more restrictive models, allows for a flexible specification not only of the technology but also of firm-level...

The paper reports the empirical results of the validation of the Stochastic Production Frontier (SPF) Model to an unbalanced panel comprising a cross-section of 8 manufacturing industries over a time span of 26 years The results provide insights on the repercussions of the micro-economic reform...

In order to simplify the representation of a technological relationship between inputs and outputs, a production unit's technology must typically satisfy some restrictive conditions, some of them being well known in the literature. This paper presents new results for aggregating labour inputs...

This paper studies the aggregate substitution and expansion effects triggered by changes in input prices, in a context where firms supply a homogenous commodity and compete in quantities à la Cournot. We derive a sufficient condition for the existence of a Cournot equilibrium and show that this...

Economic theories explain the economic growth affected by accumulation of production factors and increase in productivity and efficiency. Traditional growth theories focus on the first factor where in developing countries, and especially due to the low input of capital, serious problems arise in...
