The perverse effect of environmental regulation on emissions: The role of product-mix changes

We study the effect of environmental regulation (taxation) on emissions when the only available abatement method consists of product-mix changes. Firms choose to produce one or both varieties of a product—a pollution-intensive (dirty) and a non-pollution-intensive (green)—and compete in a differentiated Cournot duopoly. We characterize the equilibrium market structure as a function of the tax rate and show that increases in the tax can promote product-mix changes that lead to a jump in emissions for some tax range, an effect we call the perverse effect of taxation. Our work emphasizes the key role horizontal product differentiation in this process and shows that the perverse effect does not require the presence of vertical product differentiation. Further, the perverse effect of taxation is especially strong in the presence of incomplete regulation, that is, when only one of the markets is subject to taxation.     

Unequal opportunities and human capital formation

This paper develops a tractable, heterogeneous agents general equilibrium model where individuals have different endowments of the factors that complement the schooling process. The paper explores the relationship between inequality of opportunities, inequality of outcomes, and aggregate efficiency in human capital formation. Using numerical solutions we study how the endogenous variables of the model respond to two different interventions in the distribution of opportunities: a mean-preserving spread and a change in the support. The results suggest that a higher degree of inequality of opportunities is associated with lower average level of human capital, a lower fraction of individuals investing in human capital, higher inequality in the distribution of human capital, and higher wage inequality. In particular, the model does not predict a trade-off between aggregate efficiency in human capital formation (as measured by the average level of human capital in the economy) and equality of opportunity.     

Internationalization capabilities of SMEs: A comparative study of the manufacturing and industrial service sectors

Nowadays, the global economy requires developed countries to undergo industrial restructuring. In this context, industrial small- and medium-sized enterprises (SMEs) need to collaborate with the service sector to enhance their competitiveness and strategic capabilities. Indeed, industrial service SMEs have been the object of particular attention from governments since these enterprises have become a key element for manufacturing and innovation networks in developed countries. However, these firms, as well as the manufacturing SMEs they serve, now face the challenge to internationalize. This paper addresses the of the strategic capabilities required by SMEs in general, and manufacturing and industrial service SMEs in particular, to internationalize, as well as the effect of these capabilities on their export performance. These strategic capabilities are presented in a research model, which relates human resources (HR), product development capabilities and market development capabilities to export performance. In testing this model with a sample of 347 Canadian and French SMEs, similarities and differences between the two types of SMEs are highlighted.     

Effects of R & D Spillovers on the Profitability of Firms

This cross-section study of a sample of 278 firms from the COMPUSTAT II database explores the relationship between a firm's profitability and other variables, notably its own R & D capital, knowledge and market spillovers and appropriability. The proxy for knowledge spillovers is based on technological distance. Market spillovers are based on a patent input-output matrix. Both spillover proxies combine information on R & D expenditures and patent counts.The results do not reject the hypothesis that R & D has a direct, positive effect on profitability, especially in industries with effective patent protection. Information spillovers affect profits negatively, market spillovers positively.     

Dimensions of small business performance from the owner-manager's perspective: a re-conceptualization and empirical validation

Owner-managers make decisions and manage their firm as governed by the manner in which they conceptualize or ‘conceive’ performance for themselves and their firm, rather than being governed by researchers' and experts' conceptualizations of small business performance. On the basis of survey data obtained from 433 Canadian small businesses, this study aims at a deeper understanding of what owner-managers conceive performance to be, and to what extent this conception is determined by their objectives and social influences.
