In this paper two sets of issues are addressed using panel data from the manufacturing sector of five African countries. First, how high are the returns to human relative to physical capital. Second, what is the relative importance of technology and endowments of human and physical capital in...

In this paper we investigate if the predictions of three different models of capital adjustment costs are consistent with the observed investment patterns among manufacturing firms in five African countries. We document a high frequency of zero investment episodes, which is consistent with both...

This paper addresses the question if there are differences between time patterns in the volatility of investment across different industrial sectors. A competitive partial-equilibrium model with quadratic adjustment costs in investment and a GARCH demand shock is developed to predict aggregate...

We develop a new method to estimate the returns to R&D, their distribution, and their determinants. We model a continuous optimal treatment with outcome heterogeneity, where the treatment outcome depends on the applicant’s investment. The model takes into account application costs, and...

The paper measures economic loss from the problem of inadequate collateral in Bulgaria and proposes solutions consisting of creation of security interests, perfection, and enforcement.

Les interrogations nombreuses au sujet des PME en restent généralement à un constat d' insuffisance de fonds propre, confondant ainsi problème de financement et nature de celui-ci. En outre elles trouvent leur origine dans une comparaison abusive avec les grandes entreprises, ignorant des...

The paper revisits the investment simulation based on strategies exhibited by Generalized (m,2)-Zipf law to present an interesting characterization of the wildness in financial time series. The investigations of dominant strategies on each specific time series shows that longer words dominant in...

We review the changes in modelling strategy and econometric methodology when estimating a firm-level investment equation on panel data during the past twenty years, in order to assess which of these changes result from new estimation methods and changes in the practice of panel data...
