The sustainability of the commons: giving and receiving

This paper analyzes the use of a cost-free reward mechanism in the exploitation of a common property resource. We implement an experimental study involving a two-stages game where agents first decide resource appropriation and then have the opportunity to distribute cost-free bestowals. We observe that subjects link the two activities in such a way that appropriation determines the distribution of bestowals which in turn contributes maintaining low appropriation levels, thus avoiding the destruction of the common resource. Not all the potential bestowals are distributed, however.     

The tragedy of the commons revisited: The importance of group decision-making

We use a laboratory experiment to compare the way groups and individuals behave in an inter-temporal common pool dilemma. The experimental design distinguishes between a non-strategic problem where players (individuals or groups of three) make decisions without interaction and a strategic part where players harvest from a common pool. This allows us to correct for differences between individuals and groups in the quality of decisions when testing for differences in competitiveness. Group decisions are either made by majority rule or unanimity. The results show that groups are less myopic than individuals (i.e., they make qualitatively better decisions) but that they are more competitive than individuals when placed in a strategic setting. The net result for groups deciding by majority rule is that they make less efficient decisions in the strategic game than individuals do. We are able to show that this is caused by the median voter departing from her original preference in early periods with a shrinking pool. When groups have to make unanimous decisions they start playing the strategic game more efficiently then individuals do, but they rapidly become more competitive with repetition of the game.     

Cooperation in the commons

This paper delineates circumstances in which a first-best cooperative solution can be supported as a subgame perfect equilibrium in a dynamic common property renewable resource game. In a game with nonlinear resource stock effects on cost, we characterize a worst perfect equilibrium that supports cooperation for the widest range of parameter values for the discount rate, resource growth rate, harvest price, and the number of resource exploiters. The strategy profile that we propose is consistent with human behavior observed in experiments and common property resource case studies.We thank seminar participants at the University of Minnesota, the Heartland Environmental and Resource Economics Conference at Iowa State University, Keio University, and two anonymous referees for helpful comments.     

The effects of privatization on productive efficiency: evidence from the Baltic republics

By using new and unusual data sets for large samples of firms in Estonia, Latvia and Lithuania we find that, since privatization, diverse patterns of enterprise ownership have emerged and ownership configurations are quite dynamic.   To test competing theories on the productivity effects of alternative ownership structures, identical cross sectional production functions specifications are estimated for each country for varying years during 1993 1996. While the effects of private ownership upon productivity are found to vary considerably over time and across countries, productivity effects are always found to be either zero or positive, thus providing partial support for the hypothesis that state ownership is less efficient than private ownership.   Findings are mixed concerning hypotheses on the effects of particular ownership structures. Often (e.g. for Lithuania) estimates indicate that all forms of private ownership have zero productivity effects. However, some estimates for Estonia provide support for the mainstream hypothesis that outside (and especially foreign) ownership is preferred to insider ownership. But in other estimates (again for Estonia) majority ownership by employees is found to deliver better business performance than majority ownership by managers (thus refuting the hypothesis that the preferred form of insider ownership is ownership by managers).     

The choice of ownership structure: Evidence from Russian mass privatization

We use a large data set of Russian manufacturing firms to describe the ownership structure in the Russian industry at the end of the mass privatization program in 1994 and its subsequent evolution. The data shows a high, but gradually decreasing ownership stakes of firm insiders (managers and workers). We estimate the effect of a wide range of firm characteristics on the decision to privatize, the initial ownership structure after privatization, and on subsequent changes of ownership stakes. We test and find support for several predictions of the model by Aghion and Blanchard (1998). For example, collusion among workers makes them more reluctant to sell shares to outsiders. Firms in financial distress show a higher incidence of insiders selecting the option of privatization leading to high insider ownership. This can be explained by their desire to insure against unemployment in the case of restructuring by outsiders. No evidence is found of a sequencing in privatization according to the performance of firms before privatization. A methodological novelty of this paper is the application of a tobit model with sample selection to the choice of ownership stakes.     

The commons,common property,and environmental policy

The conceptual confusion among property, common property, open access resources, and the tragedy of the commons is identified and rectified. Property rights are defined and clarified. From that it is possible to understand the traditional confusion between open access resources and common property resources. It is urged that common property regimes be used in place of common property resources. This will emphasize that institutional arrangements are human creations and that natural resources can be managed as private property, as common property, or as state property. It is the property regime — an authority system — that indicates the rules of use of a variety of natural resources.     

Infrastructure privatization and changes in corruption patterns: The roots of public discontent

This paper offers a theory of how the degree of corruption that prevails in a society responds to changes in the ownership structure of major public service providers. We show that there are cases in which privatization, even though it fosters investments in infrastructure, also opens the door to more corruption. The public dissatisfaction towards privatization is then crucially affected by the changes in the degree and pattern of corruption. Our model thus helps understand the seemingly paradoxical situation prevailing in Latin America, where most studies find that privatizations have been efficiency-enhancing and have fostered investments and, at the same time, popular dissatisfaction with the process is extremely high, especially among the middle class. We show that this line of explanation is consistent with the evidence from surveys in the region.     

Monitoring and sanctioning in the commons: An application to forestry

We examine theoretical determinants of monitoring and sanctioning at both the local community level and from external government agents using the Institutional Analysis and Development (IAD) framework. We then estimate a bivariate probit statistical model to test the theory using data from 100 forests in 14 countries collected by the International Forestry Resources and Institutions (IFRI) research program. Among other things, we find that a right to harvest some portion of the resource is an important determinant of local monitoring and sanctioning. The number of external aid agencies and NGOs is an important determinant of external monitoring and sanctioning.     

Determinants of privatization of public corporations: evidence from the Japanese experience

The main purpose of this study is to find factors affecting privatization decisions. This study investigates the determinants of privatization by applying the probit model for a data set of special public corporations in Japan. In December 2001, the Japanese government made a resolution to consider the privatization of special public corporations, evaluating 74 special public corporations for possible privatization. In the empirical analysis on the determinants of privatization, we find that among several factors affecting privatization decisions, two are important—the market condition factor and the policy/regulation factor. As for market conditions, a public corporation which exists in a commercialized industry is about 20% more likely to be privatized than others. As for the policy and regulation factor, the public corporation’s privatization under a single regulator is about 25% more likely, compared with the public corporation’s privatization under multiple regulators.
