Are sequential round‐robin tournaments discriminatory?

I examine sequential round‐robin tournaments with three and four symmetric players. Each player is matched once with each other player and each match is organized as a Tullock contest. A single prize is allocated to the player with the most matches won. I show that, depending on the position of their matches in the sequence of the tournament, the players' ex ante winning probabilities and expected payoffs differ. Compared to tournaments with matches organized as all‐pay auctions, however, discrimination is weaker and partially reversed. Moreover, aggregate effort in tournaments with suitable Tullock contests is larger than in tournaments with all‐pay auctions. The fairness of round‐robin tournaments may be improved by an endogenous sequence of matches or the requirement that players fix their effort ex ante.     

Elections as a conflict processing mechanism

We examine the conditions under which societal conflicts are peacefully processed by competitive elections when the contending parties can revert to force as an alternative. We show that the viability of the electoral mechanism depends on the balance of military force, the sharpness of divisions within a society, and institutions that moderate policies implemented by winners of elections. For elections to be held and their outcomes to be respected, the probabilities that they would be won by incumbents must bear an inverse relation to the magnitude of policy changes resulting from elections. Elections are competitive when their outcomes make some but not too much difference. Constraining the scope of policy divergence increases the range of the balance of force under which elections are competitive in divided, but not in homogeneous, societies. Hence, competitiveness of elections and constitutional constraints on policies – the norms being promoted as essential for democracies – do not always go together.     

Where are the rent seekers?

In a remarkably simple and yet one of the most original and insightful observations of 20th century economics, Gordon Tullock pointed out that there are efficiency losses when public policies and political behavior create contestable rents. Tullock also observed that social losses from contesting rents appeared smaller than might be expected, so raising the question ‘where are the rent seekers?’ Tullock proposed that political accountability and ‘free-riding’ incentives in interest groups limit social losses from rent seeking. We affirm Tullock’s explanations, which apply differently under different political institutions. We compare Tullock with Gary Becker, who focused on deadweight losses from redistribution and concluded, in contrast to Tullock, that political redistribution is efficient. The comparison with Becker highlights the significance of the recognition of Tullock’s concept of rent seeking. By excluding rent-seeking losses from the social costs of redistribution, Becker could arrive at a conclusion more favorable than Tullock to an ideology that sees merit in extensive redistribution. Tullock’s model, although more encompassing of actual social costs of redistribution, would have been less welcome in the social democratic welfare state.     

The Entry‐Deterring Effects of Inflexible Regulation

This paper investigates the signalling role of tax policy in promoting, or hindering, the ability of a monopolist to practise entry deterrence. We show that environmental policy can facilitate the incumbent firm's concealment of information from potential entrants, thus deterring entry, and yet entail welfare improvements. Furthermore, we demonstrate that entry deterrence is more likely to arise when environmental regulation cannot be rapidly revised across time if market conditions change (inflexible regimes) than when regulatory agencies can adjust environmental policy over time.     

Marginal Subsidies in Tullock Contests

In a general Tullock contest, we examine a situation where a limited resource can be used to provide marginal subsidies to either player (weak or strong), or to increase the prize directly. We show that to maximize total effort, subsidizing the weak/strong player is preferred when the contest is sufficiently accurate/inaccurate. This result generalizes to n‐player lottery contests. In a lottery contest (Tullock contest with ), we derive the optimal scheme for a full range of resource: when the resource is small, it is optimal to only subsidize the weak player; when it is large, both players should be subsidized simultaneously.     

When less is more: Rationing and rent dissipation in stochastic contests

This paper shows how to maximize revenue when a contest is noisy. We consider a case where two or more contestants bid for a prize in a stochastic contest where all bidders value the prize equally. We show that, whenever a Tullock contest yields under-dissipation, the auctioneer?s revenue can be increased by optimally fixing the number of tickets. In particular, in a stochastic contest with proportional probabilities, it is possible to obtain (almost) full rent dissipation. We test this hypothesis with a laboratory experiment. The results indicate that, as predicted, revenue is significantly higher in a lottery with rationing than in a standard lottery. On the other hand, an alternative rationing mechanism that does not limit total expenditures fails to increase revenue relative to a standard lottery.

Gordon Tullock as a political scientist

We consider Gordon Tullock’s impact in political science, focusing on his influence as a scholar and as an academic entrepreneur. It is common to think of Tullock as a “natural economist,” but his formal training at Chicago encompassed considerable coursework related to political science. We consider three sources of information to draw conclusions about Tullock’s contributions in political science: (1) Course syllabi; (2) Citations in academic political science journals; and (3) Impact on the careers of important political scientists, and shaping the intellectual agenda. Our conclusion is that, while Tullock’s work is clearly significant for central questions in political science, and has received some attention, his primary legacy lies in the impact he had on launching and shaping the careers of prominent political scientists, and thus the development of political science scholarship.     

Follow the leader? How leadership behavior influences scientists’ commercialization behavior (or not)

In this study we analyze the impact of organization leaders on their fellows’ behavior in academia by utilizing the unique structure of the Max Planck Society. The latter is a leading research organization in Europe with autonomous institutes which center around appointed directors. Using panel data of commercialization activities and royalties received in the period 1980–2007, we observe that both director engagement in disclosure activity and royalty shares received at the institute level lead to a significant increase in invention disclosure by non-directors in the following year. Yet, both effects are only significant when regarding short-term time lags of one year. Utilizing information based on a survey performed with Max Planck scientists in 2007 we find that scientists’ perceived academic relevance of commercialization neither relates to previous director involvement in disclosure activity nor to previous overall disclosure efforts within the institute. We conclude that directors have a short-term impact on fellow scientists’ behavior while there is hardly any long-lasting impact on scientists’ attitude or behavior. Thus, scientists’ adaption to director behavior in academia is rather symbolic.     

Vox Populi,Vox Dei? Tacit collusion in politics

We study competition between political parties in repeated elections with probabilistic voting. This model entails multiple equilibria, and we focus on cases where political collusion occurs. When parties hold different opinions on some policy, they may take different policy positions that do not coincide with the median voter's preferred policy platform. In contrast, when parties have a mutual understanding on a particular policy, their policy positions may converge (on some dimension) but not to the median voter's preferred policy. That is to say, parties can tacitly collude with one another, despite political competition. Collusion may collapse, for instance, after the entry of a new political party. This model rationalizes patterns in survey data from Sweden, where politicians on different sides of the political spectrum take different positions on economic policy but similar positions on refugee intake—diverging from the average voter's position, but only until the entry of a populist party.     

The Impact of Lifecycle Events on Women's Labour Force Transitions: A Panel Analysis*

This panel study explores the impact of different lifecycle events on women's labour force transitions. We explicitly investigate whether the factors that determine entry into the labour force differ from the factors that determine withdrawal from the labour force. The results demonstrate that labour force transitions – entry and withdrawal – occur more frequently among young women. The event of childbirth is strongly associated with labour force withdrawal, while marital separation and reductions in family earnings are strongly associated with labour force entry. Moreover, labour force transition probabilities are more sensitive to income‐reducing events than to income‐supplementing events.     

Morale,performance and disclosure

We study the optimal disclosure policy in a sender–receiver communication game where the receiver's morale, defined as his expected state of the world, affects his performance. The sender observes the state and chooses whether to disclose it to the receiver, who then decides whether to participate in a task. The receiver wins if his performance in the task meets a target. No disclosure is optimal if the receiver wins with average morale in each state. Otherwise, in the threshold disclosure equilibrium that Pareto-dominates full disclosure, the receiver quits as the sender discloses the worst states and wins as the sender withholds the rest. The receiver wins in more states in the Pareto-optimal equilibrium as the sender chooses a non-monotonic disclosure policy. Our theory reveals a trade-off between transparency and efficiency when morale affects performance. It has applications in a broad range of areas including military, family, education and business.     

Risk aversion in symmetric and asymmetric contests

We analyze existence, uniqueness and properties of equilibria in incompletely discriminating Tullock contests with logistic contest success functions, when contestants are risk averse. We prove that a Nash equilibrium for such a contest exists, but give an example of a symmetric contest with both symmetric and asymmetric equilibria, showing that risk aversion may lead to multiple equilibria. Symmetric contests have unique symmetric equilibria but additional conditions are necessary for general uniqueness. We also study the effects on incumbents of additional competitors entering the contest under these conditions and examine the effects of risk aversion on rent dissipation in symmetric and asymmetric contests.     

FDI Policy,Greenfield Investment and Cross‐border Mergers

This paper examines a multinational's choice between greenfield investment and cross‐border merger when it enters another country via foreign direct investment (FDI) and faces the host country's FDI policy. Greenfield investment incurs a fixed plant setup cost, whereas the foreign firm obtains only a share of the joint profit from a cross‐border merger under the restriction of the FDI policy. This trade‐off is affected by market demand, cost differential, and market competition, among other things. The host country's government chooses its FDI policy to affect (or alter) the multinational's entry mode to achieve the maximum social welfare for the domestic country. We characterize the conditions shaping the optimal FDI policy and offer intuitions on FDI patterns in developing and developed countries.     

Tacit Coordination in a Decentralized Market Entry Game with Fixed Capacity

We focus on a class of market entry games in which a newly emergent market opportunity may be fruitfully exploited by no more than a commonly known, exogenously determined number of firms. Our results show significant effects of the parameters manipulated in the study, namely, the market capacity, entry fee, and method of subject assignment to groups (fixed vs. random). In contrast to previous market entry games with linear payoff functions, we find no evidence of convergence to equilibrium play on the aggregate level. Shifting the focus of the analysis from the aggregate to the individual level, four clusters of subjects are identified. The patterns are: (1) choice of the same action that is independent of the parameters of the game or the outcome of previous presentations of the same game; (2) random choices with probabilities prescribed by the equilibrium solution for risk-neutral players; (3) random choices with probabilities equal to the individual observed overall proportion of entry; and (4) sequential dependencies that violate any model that assumes randomization. Subjects in the fourth and largest category are shown to adjust their choices in accordance with a simple principle of strategic reasoning.     

“Remembrance of things past”: Gordon Tullock,the man and the bioeconomist

My tribute paper on Gordon Tullock (1922–2014) provides some memorable stories of Tullock as a person and as a founder of bioeconomics. I include my speech, “Toast and roast: Gordon Tullock,” delivered on the occasion of Tullock’s 80th birthday; also the same “Toast and roast....,” written in the form of a poem, “Ode to Gordon Tullock.” I also discuss Tullock’s contributions to bioeconomics. In a concluding section, I recall a couple of my poignant memories of Gordon Tullock.     

Indecision Theory: Weight of Evidence and Voting Behavior

In this paper, we show how to incorporate weight of evidence, or ambiguity, into a model of voting behavior. We do so in the context of the turnout decision of instrumentally rational voters who differ in their perception of the ambiguity of the candidates' policy positions. Ambiguity is reflected by the fact that the voter's beliefs are given by a set of probabilities, each of which represents in the voter's mind a different possible scenario. We show that a voter who is averse to ambiguity considers abstention strictly optimal when the candidates' policy positions are both ambiguous and they are “ambiguity complements.” Abstaining is preferred since it is tantamount to mixing the prospects embodied by the two candidates, thus enabling the voter to “hedge” the candidates' ambiguity.

Empirical Analysis of Entry in the Local Exchange Market: The Case of Pacific Bell*

This article examines local exchange entry in SBC's California territory. Analysis is conducted based on five‐digit zip code areas. Information on economic, demographic, and regulatory variables, including prices of unbundled loops, is included in the analysis. Results of censored Poisson analysis indicate that these economic, demographic, and regulatory variables play a statistically significant role in leading to higher probabilities of low levels of entry in areas where loop prices are higher, fewer large businesses exist, and costs of self‐provision are higher.

Waste disclosure and corporate cash holdings

ABSTRACT

In this paper, we address an important and emerging question: Can firms’ voluntary waste disclosure affect corporate cash holdings? Using a sample of S&P 500 firms, we find strong evidence for a positive relationship between waste disclosure and the cash holding policy of firms. Furthermore, we find that waste disclosure significantly increases cash holdings only for firms with strong corporate governance quality. We also find that the significant relationship between waste disclosure and cash holdings remains unchanged only for firms that operate in environmentally sensitive industries. Our paper provides novel evidence on the role of voluntary waste disclosure as an environmental dimension that influences the cash policy of firms and highlights the little-known issue of waste disclosure as a significant research topic.
