The role of the private sector under insecure property rights

It is well known that the so-called voracity effect can be observed in an economy with a weak property rights system. Voracious behavior is regarded as one of the excess uses of the common assets. In this paper, we seek to examine voracious behavior from a different perspective by introducing a new direction of capital flow: from the private sector to the common sector. A government mandates that all competing interest groups invest their private capital in the common sector to mitigate the effects of excess use of the commons. In this situation, we study how this capital flow affects the voracious behavior of the groups and the growth rate of the economy. The main findings are that, while there is no standard voracity effect, an increase in the contribution of the private sector into the common sector causes more voracious behavior and thus reduces economic growth. This suggests that policies designed to preserve the commons can lead to a harmful effect on the economy.     

The effect of environmental uncertainty on the tragedy of the commons

We model a common pool resource game under environmental uncertainty, where individuals in a symmetric group face the dilemma of sharing a common resource. Each player chooses a consumption level and obtains a corresponding share of that resource, but if total consumption exceeds a sustainable level then the resource deteriorates and all players are worse-off. We consider the effect of uncertainty about the sustainable resource size on the outcome of this game. Assuming a general dynamic for resource deterioration, we study the effect of increased ambiguity (i.e., uncertain probabilities pertaining to the common resourceʼs sustainable size). We show that whereas increased risk may lead to more selfish behavior (i.e., to more consumption), increased ambiguity may have the opposite effect.     

Insecurity of property rights and social matching in the tenancy market

This paper shows that insecurity of property rights over agricultural land can have large efficiency and equity costs because of the way it affects matching in the tenancy market. A principal-agent framework is used to model the landlord's decision to rent when he takes into account the risk of losing the land to the tenant and when contract enforcement is decreasing in social distance with the tenant. These effects are quantified for the case of local land rental markets in the Dominican Republic. Results show that insecure property rights lead to matching in the tenancy market along socio-economic lines, severely limiting the size of the rental market and the choice of tenants for landlords, both with efficiency costs. Social segmentation reduces access to land for the rural poor, with high equity costs. Simulations suggest that improving tenure security would increase rental transactions by 21% and the area rented to the poor by 63%. Increased property rights security is hence beneficial not only to asset owners, but also to those with whom they might interact in the market.     

The structure of optimal tariff rates in a large country with market power

We theoretically analyze the optimal tariff problem that arises in a large country with market power. By using a model with more than two traded goods, we derive (1) the condition for optimal import tariff rates to be ranked, and (2) the condition under which the optimum import tariff becomes uniform. These conditions are established in a three-good model and in an N-good model. The results are evaluated on the basis of compensated excess demand elasticity, and hence do not require information on income effects. I would like to thank Tatsuo Hatta, Makoto Okamura, Katsuhiko Suzuki and two anonymous referees for their helpful comments and suggestions.     

The elasticity of demand for wagering in an unregulated market

The literature estimating the take-out rate (price) elasticity of horse race wagering has consistently found values far above one. The persistence of these apparently inefficiently high prices can be attributed to institutional factors of the US market where federal taxes are imposed on the total amount wagered, and not on the bookmakers’ revenue. By investigating all horse races in New Zealand from August 1993 to April 2009, our article is the first one to consider price setting for wagering in an unregulated market where taxes for a monopolistic betting agency are based on revenues. In such a setting, one would expect elasticities close to one, but in all econometric specifications, we find values well below one. We identify two reasons why higher prices could nevertheless reduce profits: cross price elasticities are negative and, due to the specific features of parimutuel betting, international competitors may only be attracted when take-out rates are above a critical threshold.     

Disagreement over the emergence of private property rights: alternative meanings, alternative explanations

This paper is an exercise in the history of thought, which compares Austrian and neoclassical theories of the emergence of private property rights, and examines, in part, the extent to which Austrians can be said to offer a commonly-agreed upon explanation that parallels Carl Menger's exemplary story of the emergence of money. We address the sources of disagreement (and apparent conflict) among emergence theorists in both schools. We try to show that some of the disagreement hinges on an unclear meaning of the term “emergence,” which is resolvable, while other sources of disagreement are fundamental at the methodological level.

Security design,market risk and round quotes in the treasury bond market

Prior literature finds that the tendency of price-endings to cluster on rounder fractions increases with price volatility. We estimate the separate influences and relative importance of the determinants of price volatility, security design and market risks. Our data is from a market setting that is ideal for isolating and studying the relations of interest. Results for both quote and trade prices indicate that the tendency to use round price-endings increases with both a security’s inherent risk, attributable to security design, and variation over time in market risks. Security design influences clustering more than market risks, but market risks are influential in determining clustering once security design is fixed. The estimated effects are strongest in the on-the-run market segment where liquidity facilitates the aggregation of information into price.

Rent-seeking and the tragedy of the commons: two approaches to problems of collective action in biology and economics

I am interested in how models, practices, and concepts travel across specialties and thereby change and are changed in turn. In the present essay I discuss Gordon Tullock’s ideas about the relationship between biology and economics in the light of his correspondence with the biologist Garrett Hardin. Tullock contributed to one of Hardin’s edited projects, but they took different approaches to related problems, which I characterize as problems of coordinated action. Tullock saw that he and Hardin were up to a similar line of inquiry, and Hardin engaged with him up to a point, but ultimately the biologist differed with the economist regarding the potential for the reliability of a regulating power such as the state.     

The reverse tragedy of the commons: an exploratory account of incentives for under-exploitation in an open innovation environment*

This paper presents an empirical account of a phenomenon that we refer to as the ‘reverse tragedy of the commons’ in open innovation. The name signifies the ‘under-exploitation’ of intellectual property (IP) under weak appropriability. The name is this graphic because the tragedy is costly, and can also render IP effectively worthless and block innovation in the short to medium term. We propose that the tragedy is borne out of the interaction between enterprise characteristics, a competitive setting and the framework that is set by the policy intervention. This finding is pertinent to policy-makers with regard to the design of research, development and innovation instruments, as well as managers who must determine how to implement open practices in innovation.     

The role of property rights in determining the environmental quality-income relationship

This paper examines the role of property rights in shaping the relationship between environmental quality and income. It develops an analytical framework that integrates the effects of property rights evolution, natural resource attributes, agent characteristics, and production technology on the environment-income relationship. The substantive strength of this framework lies in its ability to rationalize a wide range of environment-income relationships. The model shows that the U-shaped environment-income relationship, which is consistent with the Environmental Kuznets Curve (EKC) hypothesis, can arise only under specific model conditions. Thus the framework provides an additional explanation for non-universality of EKC. We provide evidence in support of our framework from case studies of various natural resources.     

The role of contracts and intellectual property rights in open innovation

Our exploratory empirical study, based on interviews and a survey of firms, addresses a number of questions on the role of formal contracts and intellectual property rights (IPR) in the context of firm-to-firm open innovation (OI). We find that firms active in OI have a very strong preference for the governance of their OI relationships with other firms through formal contracts. Also, despite the open nature of OI, firms still see IPR as highly relevant to the protection of their innovative capabilities. We find the degree of openness of firms, their formal legal attitude, and the competitive dynamics of their product market environment to be related to the preference of OI firms for IPR. Furthermore, the strength of firms’ internal R&D capabilities increases the positive relationship between openness and the preference for IPR.

The external cost of asbestos in the housing market

This study uses a Generalized Method of Moments spatial error hedonic model to estimate the potential impact of asbestos on residential property prices. The analysis examines a large sample of 32,403 housing sales occurring between 2008 and 2015 in a fast-growing Coastal Alabama region. Results indicate the presence of asbestos depreciates house values by 13.44%, translating into an external cost of approximately $25,300 per property.     

Scale economies with regard to price adjustment costs and the speed of price adjustment in Australian manufacturing

This paper aims to examine the impact of firm size, industry concentration and the length of production on industry speed of price adjustment. To motivate the paper, an industry pricing model in error correction form is derived from firm pricing behaviour. As a new development, firms are assumed to have price adjustment costs that are a function of their size. The empirical model is estimated using two‐digit Australian manufacturing industry data for the period 1994:3 to 2006:1. The results suggest that the industry speed of price adjustment is positively related to firm size and negatively related to industry concentration and the production lag. Implied values for industry speeds of price adjustment are generally small when compared to other country industry studies. However, the industry average median lag of 7.1 quarters indicates a slightly faster speed of price adjustment than the estimate for the Australian consumer price index by Dwyer and Leong (2001 Dwyer, J. and Leong, K. 2001. Changes in the determination of inflation in Australia 1–44. Reserve Bank of Australia Research Discussion Paper 2001‐02 [Google Scholar]).     

The relevance of private information in mechanism design

Recent results in mechanism design show that as long as agents have correlated private information and are sufficiently risk neutral, it is possible to design mechanisms that leave agents with arbitrarily small information rents. We show that these full-rent-extraction results hinge on the implicit assumption that the agents’ beliefs uniquely determine their preferences. We present an example of the voluntary provision of a public good in which this assumption is relaxed, and consequently, even in highly correlated environments, if agents’ beliefs do not uniquely determine their preferences, then the extraction of the agents’ entire information rents is impossible.

Costly enforcement of property rights and the Coase theorem

We examine a setting in which property rights are initially ambiguously defined. Whether the parties go to court to remove the ambiguity or bargain and settle before or after trial, they incur enforcement costs. When the parties bargain, a version of the Coase theorem holds. However, despite the additional costs of going to court, other ex-post inefficiencies, and the absence of incomplete information, going to court may ex-ante Pareto dominate settling out of court. This is especially true in dynamic settings, where obtaining a court decision today saves on future enforcement costs. When the parties do not negotiate and go to court, a simple rule for the initial ambiguous assignment of property rights maximizes net surplus. A paper circulated under the same title and dated 6 March 2000 contained the basic structure examined in this paper, but did not develop many of the results reported here. For comments, we would like to thank participants at the WZB-CEPR contests conference and seminar audiences at the University of Southern California, the University of British Columbia, UC Davis, and UC Riverside.
