Human capital and technical efficiency: a Stochastic Frontier Analysis of Caribbean firms

Abstract

ABSTRACTTechnical efficiency is the ability of a firm to produce its maximum output using a set of inputs or to minimise the use of its inputs to produce a certain level of output. When a firm is operating at its most efficient, operating costs can be minimised, profits maximised and competitiveness improved. This study investigates the role of a firm’s human capital in impacting its technical efficiency. It uses the Productivity, Technology, Innovation survey (PROTEqIN) conducted for a sample of 13 Caribbean countries in 2014 and comprises 1,966 firms. To account for differences in efficiency of firms, a Stochastic Frontier Analysis is used to estimate the production function as well as technical efficiency scores. The efficiency scores are then regressed against workforce characteristics and other firm-specific control variables using a Tobit estimator with robust standard errors. The results suggest that workforce characteristics, in particular workforce composition in terms of the proportion of managers to total workforce and graduate and post-graduate education play an important role in influencing firm efficiency, perhaps more so than other firm-specific variables. Lastly, government technical assistance programmes in the Caribbean also act to improve firm technical efficiency.
