“Managing” Corporate Community Involvement

In academic research, many attempts have been undertaken to legitimize corporate community involvement by showing a business case for it. However, much less attention has been devoted to building understanding about the actual dynamics and challenges of managing CCI in the business context. As an alternative to existing predominantly static and top-down approaches, this paper introduces a social movement framework for analyzing CCI management. Based on the analysis of qualitative case study data, we argue that the active role of employees pressuring for CCI policies and practices, as well as the organization audience responses to their efforts, are at the core of the challenges involved in managing CCI. These challenges also pose limits to how far CCI can be extended to a “business as usual” activity.     

Evolution in games with a continuous action space

Allowing for games with a continuous action space, we investigate how evolutionary stability, the existence of a uniform invasion barrier, local superiority and asymptotic stability relate to each other. This is done without restricting the populations of which we want to investigate the stability to monomorphic population states or to strategies with finite support. The authors have benefitted from careful and precise comments by Gerard van der Laan, Jan van Mill, the editor and an anonymous referee.

Testing the induced innovation hypothesis: an error correction model of South African agriculture

This paper applies cointegration techniques to a model of induced innovation based on the two-stage constant elasticity of substitution (CES) production function. This approach results in direct tests of the inducement hypothesis, which are applied to data for South African commercial agriculture for the period 1947–1991. South African data is used because the policy changes have been substantial enough that the factor and price ratios have turning-points, rather than being monotonie. The time series properties of the variables are checked, cointegration is established, and an error correction model (ECM) constructed, allowing factor substitution to be separated from technological change. Finally, the ECM formulation is subjected to causality tests, which show that both the factor price ratios and R&D and extension expenditures are Granger-prior to the factor-saving biases of technological change. Thus, each stage of the analysis corroborates the inducement hypothesis. However, straightforward price-inducement is only part of the explanation of changes in factor ratios. Policy-induced innovation, in response to tax concessions and subsidised credit, is also present.     

Renewable resource management, user heterogeneity, and the scope for cooperation

Cooperation can increase the efficiency of commonly-owned renewable resource use. However, received knowledge is that, absent side payments, cooperative solutions are more difficult to achieve the less homogenous the agents involved. We revisit this claim by analyzing how differences in the opportunity costs of resource harvesting affect the scope for Pareto-improving contracts, where contracting is with respect to the type of technology used. We find that the scope for cooperation is largest for intermediate levels of heterogeneity.
