Abstract

Recently, within several debates, the idea of a participatory economy has been recovered as a viable solution towards labour and firm’s costs flexibility to cope with unemployment and the increasingly competitive economic environment. This paper is an attempt to integrate the main recent models of participatory economy, i.e. Weitzman’s share economy and Meade’s partnership economy. This in order to throw light on some microeconomic conditions which appear to be not thoroughly examined and which could make not smoothly viable the path of a share economy. We introduce workers’ risk aversion in Weitzman’s model showing that with Von Neuman-Morgestern utility, worker’s preference for a share contract rather than a traditional wage one depends on the (mainly subjective) probability of unemployment in the two systems and that a risk premium may emerge which increases marginal cost of labour in a share system. On the other hand the firm would prefer the share solution only if an improvement in its expected revenue occurs as a consequence of it, e.g. through higher labour productivity or lower transaction costs. The increase in expected revenue must be sufficient to finance the risk premium through the whole lenght of the share labour contract. Since this condition could be hard to come true (inreasingly with the degree of participation) and thus Weitzman’s share economy not viable in a risk-aversion world, we argue that Meade’s model (which includes some degree of management sharing) is a good solution to “institutionalise” the risk premium. We show the intrinsic equivalence — with respect to labour compensation — of the two models, a property which allows the integration to solve the risk problem. However a fundamental difference arises within the sphere of property rights, an aspect wich is deepened in the appendix. Finally, using a game-theoretical framework, we analise the strategic aspects of firm’s choice for a participatory or a traditional wage model, obtaining a set of conditions on relative profits and labour demanded which helps to understand when and where a share economy may arise. We conclude stressing that, even if every condition regarding workers’ and firms’ preferences for a share solution were satisfied, a share economy needs the development of some kind of permanent training system, in order to provide workers with indispensable competences (cultural and professional) vitally to the working of a share system where risk were institutionally offset through participation to management as well.
