This paper presents results of a meta-regression analysis on empirical estimates of capital-energy substitution. Theoretically it is clear that a distinction should be made between Morishima substitution elasticities and cross-price elasticities. The former represent purely technical...

We develop a model of directed technological change, frictional unemployment and migration to examine the effects of a change in skill endowments on wages, employment rates and emigration rates of skilled and unskilled workers. We find that, depending on the elasticity of substitution between...

Firms in developed countries face increasing shortages of young workers. This paper studies the importance of young workers, particularly vocational trainees, for firm technology investments. Leveraging exogenous variation in trainee supply caused by an education reform in Germany in 2001, I...

We study the impact of broadband availability on firms’ total factor productivity (TFP) using German firm-level data between 2010 and 2015. We adopt a control function approach to causally identify and separately estimate productivity for 46 two-digit manufacturing and service sectors. Over...

This paper aims to investigate the determinants of productivity growth in the Tunisian economy context over the period 1976 to 2010. Our theoretical model incorporates as key variables, domestic innovation, human capital, distance to technology frontier and external technology spillovers through...

In the neoclassical production functions model technical change (TC) is assumed to be exogenous and it is specified as a function of time. However, some exogenous external factors other than time can also affect the rate of TC. In this paper we model TC via a combination of time trend (purely...

Hastened by triangle trade patterns, exchange of immediate goods and inward foreign direct investment have become the main channels to achieve technical spillover. Based on regional inward capital data and classified traded goods, we examine causes of innovation in the context of inward foreign...
