This paper is concerned with empirical measurement of patterns of productivity growth by means of competing panel data models of technical change. We argue that short term analysis must rely on models of technical change which are more flexible than the standard time trend model, because...

The availability of new internationally-harmonized innovation survey data collected from OECD countries has created some interesting opportunities for studying the following two key areas: (1) the determinants of innovation behavior at firm level, and (2) innovation as an important factor...

This paper is an empirical analysis of knowledge capital and performance heterogeneity at the firm level. We apply new econometric methods to extensive data on innovation and innovative activities in Swedish manufacturing. Knowledge capital, defined as the ratio of innovation sales to total...

This paper is concerned with the estimation of an employment relationship and employment efficiency under production risk using a panel of Zimbabwe's manufacturing industries. A flexible labour demand functions are used and consist of two parts: the traditional labour demand function and labour...

Agricultural reform in a rural economy, comprising two separable landholding classes is analyzed in an over-lapping generations framework. "The poor" work the land and have children to provide for family labor and old age support. "Landlords" only use hired labor and maximize profits. It is...

In an overlapping generations framework, the effects of exogenous changes in child mortality on fertility and parental welfare in the short run and on fertility, population density and parental welfare in the long run is analyzed in a primitive, land-constrained economy. In a first step a...

A short review of different types of motives in fertility decisions is given, followed by a discussion on the characteristics of societies where the insurance and producer goods motives are important. Three models investigating the effects of different types of policy interventions in such...

An overlapping generations framework is employed in order to study consequences of the old-age security and producer goods motive for having children in a rural economy. The model predicts growth in total output combined with declining fertility and increasing population density and per capita...

This paper investigates the time-path of efficiency and productivity change in the case of the Romanian cement industry 1966-1989. The analysis is based on different specifications of stochastic frontier models. The efficiency scores and the time paths of efficiency and technical change are...
