Using data from a randomized control trail in Sri Lanka, this paper explores whether cash and in-kind grants helped microenterprises approach the productivity level of SMEs.  The paper first estimates production functions and subsequently treatment effects on TFP levels.  Most significantly,...

We construct a unique panel dataset to examine how R&D and intellectual property (IP), via patents and trade marks, increase firm productivity. Knowledge has public good characteristics of non-depletability and non-excludability. Even with IP, imitation and inventing around other firm`s products...

This paper analyses and quantifies the effects of trade liberalisation and skill-biased technical change, both exogenous and trade-induced, on the skill premium and real wages of unskilled and skilled workers in the Mexican manufacturing sector, using industry- and firm-level data for 1984-1990...

This paper develops a sequential learning estimator of production functions and productivity dynamics for unbalanced establishment panels. Extending an idea from the literature on dynamic industry models, establishments are uncertain about their own idiosyncratic productivities and update...

This paper uses novel data on trade mark activity of UK manufacturing and service sector firms to investigate whether trade marks improve the profitability and productivity of firms. We first analyse Tobin`s q, the ratio of stock market value to book value of tangible assets. We then investigate...

The labour productivity differentials between manufacturing firms in Ghana and South Korea exceed those implied by macro analysis.  Median value-added per employee is nearly 40 times higher in South Korea than Ghana.  The most important single factor in explaining this difference is the...

In this paper we ask how technological differences in manufacturing across countries can best be modeled when using a standard production function approach.  We show that it is important to allow for differences in technology as measured by differences in parameters.  Of similar importance are...

Three dimensions of the performance of firms in Ghana’s manufacturing sector are investigated in this paper: their technology and the importance of technical and allocative efficiency. We show that the diversity of factor choices is not due to a non-homothetic technology....

Three dimensions of the performance of firms in Ghana’s manufacturing sector are investigated in this paper: their technology and the importance of technical and allocative efficiency. We show that the diversity of factor choices in not due to a non-homothetic technology. Observable...

This paper presents an industry equilibrium model of vertical integration under contractual imperfections with specific input suppliers and external investors.  I assume that vertical integration economizes on the needs for contracts with specific input suppliers at the cost of higher fixed...
