Measuring the immeasurable — A survey of sustainability indices

Sustainability indices for countries provide a one-dimensional metric to valuate country-specific information on the three dimensions of sustainable development: economic, environmental, and social conditions. At the policy level, they suggest an unambiguous yardstick against which a country's development can be measured and even a cross-country comparison can be performed. This article reviews the explanatory power of various sustainability indices applied in policy practice. We show that these indices fail to fulfill fundamental scientific requirements making them rather useless if not misleading with respect to policy advice.     

An investigation of path-goal leadership theory and its impact on intrachannel conflict and satisfaction

This path-analytic study examined the relationships among channel members’ perceptions of dimensions representing channel leader behavior, channel conflict and satisfaction. In doing so, the path-goal theory of leadership is tested in a franchise channel of distribution. The results indicate that both the consideration and the initiating structure dimensions of leader behavior significantly influence franchisees’ satisfaction with the franchise arrangement. As defined in the theory, these relationships were found to be mediated by the existing level of conflict being experienced by franchisees. Causal linkages are also found between intrachannel conflict and satisfaction. Specific recommendations are provided to franchisors and other channel leaders.     

Testing a DSGE Model of the EU Using Indirect Inference

We use the method of indirect inference, using the bootstrap, to test the Smets and Wouters model of the EU against a VAR auxiliary equation describing their data. We find that their model generates excessive variance compared with the data. But their model fits the dynamic facts quite well if the errors have the properties assumed by SW but scaled down. We compare a New Classical version of the model which also performs reasonably if error properties are chosen using New Classical priors (notably excluding shocks to preferences). Both versions have (different) difficulties fitting the data if the actual error properties are used. A model combining rigid and flexible-wage/price sectors, with a weight of around 5% on the rigid sector, does best in fitting the data.     

REINVENTING THE WHEEL? AFRICAN COOPERATIVES IN A LIBERALIZED ECONOMIC ENVIRONMENT

ABSTRACT ** :  Cooperative development in Africa can be said to have traversed two main eras: the era of state control and that of liberalization. The first era lasted up to the early 1990s and saw the origin and substantial growth of cooperatives on the continent. During that period, different models of cooperative development were introduced on the continent. We distinguish a unified cooperative model, a social economy model, a social movement model, a producers' model and an indigenous model. But in all cases, cooperatives were engulfed into state politics. However, little is known about the impact of liberalization measures on these models. Our research in 11 African countries reveals that cooperatives in Africa have survived the market forces and continued to grow in number and membership. We see a slow but sure erosion of the unified model and the adoption of a social economy model. Cooperatives in Africa are re-examining their organizational forms and diversifying their activities in response to members' interests and needs.     

Dynamic inefficiency in an overlapping generations economy with production

Reichlin [Equilibrium cycles in an overlapping generations economy with production, J. Econ. Theory 40 (1986) 89-102] has shown in an OLG model with productive capital that whenever the steady state is locally indeterminate and undergoes a Hopf bifurcation, it is Pareto-optimal. While these results were established under the assumption of Leontief technology, the author has partially extended them to show that the Hopf bifurcation is robust with respect to the introduction of capital-labor substitution. In this note, we prove that the Pareto-optimality of the steady state does not extend to technologies with capital-labor substitution. When the steady state is a sink or undergoes a Hopf bifurcation, it is characterized by over-accumulation with respect to the Golden Rule—the interest rate is negative—hence not Pareto-optimal. Most importantly, it follows that stabilization policies targeting the steady state leave room for welfare losses associated with productive inefficiency, apart from the very special case of Leontief technology.

Can Voluntary Workplace Partnership Deliver Sustainable Mutual Gains?

This article draws on two Irish case studies to examine the nature and outcomes of voluntary workplace partnership (WP), and the conditions affecting its durability. We found that WP delivered mutual gains for all stakeholders at Aughinish Alumina (AAL), which were quite equally divided. While WP delivered most gains for management at Waterford Crystal (WC), and some for the union, worker gains were less. The WC partnership broke down after 10 years, but the AAL partnership continues. Voluntarist mutual gains partnership is feasible, but success and durability depends on specific clusters of contextual conditions, notably management support, a quality‐focused competitive strategy, insulation from market pressures, union postures, vertically aligned bundles of mutual gains practices, institutional supports, emphasis on fairness, all party commitment to performance enhancement and capital‐intensive technology. Conditions supporting WP were stronger at AAL than WC. More generally, as supports for WP in Ireland are weaker than retardants, we conclude that few mutual gains partnerships will take root, and even fewer will endure.
