This paper has examined a rent-seeking game where the players take a more sophisticated approach to evaluating the potential strategies and counter-strategies of their rivals than in the standard Nash case. We have derived the conditions for the existence of symmetric and nonsymmetric equilibria for the game and derived the properties of these equilibria. Three results merit repeating. First, we find that rent dissipation will not, in general, be complete. Second, and in contrast to much of the traditional literature, we find that the socially optimal result of zero rent-seeking is sometimes a feasible equilibrium outcome for our game. Finally, there exist rent-seeking configurations in which the best play of one of the rivals is to withdraw from the game or, alternatively stated, where it is not optimal for a rival to contest the rent by entering the game. In these nonsymmetric cases it would appear that Tullock's conjecture about the value of preemptive moves remains valid. This is true even when the strategies and counter-strategies available to the players are much more complex than in the traditional Nash approach.As a final point we raise the issue of whether or not it is reasonable to suppose that the players in rent-seeking games will take their strategy and counter-strategy sets to be as large as we have assumed in this paper. Players may well make their moves and counter-moves based upon rules of thumb or other considerations that effectively bound the strategy sets of the players. As well, it may be useful to consider games where players, upon entering the game, commit themselves to a given level of expenditures. Many of these issues are considered in a related paper by the authors.  相似文献

This article will outline the politics and pathways of promotion among government officials working in a rural county in Anhui province and their attitudes towards elite status. It will analyze the implications these processes and pathways have for the operation of local government in rural China. Drawing on interviews and relationships spanning a ten-year period (2004–2013), this article primarily relies upon the personal experiences of colleagues and friends who have attempted to rise through the ranks of government and business in Benghai County, with varying degrees of success. While the article will focus on political elites, in Benghai it is impossible to separate business from politics. This article will delineate strategies adopted for career advancement and attaining elite political status, and the effects these strategies have on the relationship between political elites and ordinary cadres.  相似文献

Legal context. The House of Lords held that the medical privacyof the glamorous supermodel Naomi Campbell was violated by publicationof details of her drug addiction treatment and a paparazzi picture.English law is developing under the influence of Article 8 (theright of privacy) and Article 10 (the right of freedom of expression)of the European Convention of Human Rights. The court explainedhow the action for breach of confidence protects privacy. So,who controls the Naomi Campbell information flow? Key points. Primarily, the courts control the flow of privateinformation. They do so through the cause of action of breachof confidence and remedies. In deciding liability, the courtsshould ask whether the benefit of publication is proportionateto the harm done by the invasion of privacy. To answer the question,they must balance the public interest in the right of privacyagainst the public interest in the right of freedom of expression.They may settle on a Reynolds type test by considering a numberof non-exhaustive factors. The article examines seven suggestedfactors and the remedies which can be deployed by the courts.Judgments from the English courts and the European Court ofHuman Rights are considered, including Campbell v MGN (HL),Douglas v Hello! (CA), McKennitt v Ash (HC), Peck v UK (ECtHR),Édition Plon v France (ECtHR), and Von Hannover v Germany(ECtHR). Practical significance. There are an increasing number of privacyclaims against the media. The article includes a checklist ofseven factors to help determine where the balance lies betweenprivacy and freedom of expression.  相似文献

What is the best way to reflect human diversity in the structure of the provocation defence, and similar excusatory defences in the criminal law? The House of Lords recently concluded that the right way is to allow the jury to personalise and thereby qualify the apparently uniform ‘reasonable person’ standard mentioned in section 3 of the Homicide Act 1957. In this paper we argue that this is not the right way at all. We argue that the reasonable person standard, unqualified, already accommodates the only variations between people that the law should want to accommodate in an excusatory defence. To defend this view we revive the common law's tripartite analysis of the ‘objective’ (or impersonal) issues in the provocation defence: first, was there an action capable of constituting a provocation? second, how provocative was it? and third, how much self‐control should have been exhibited in the face of it? We show that these questions each have a built‐in sensitivity to certain variations between different defendants' situations, but that this does not detract from their objectivity (or impersonality). We argue that no more sensitivity is needed in the name of human diversity, and what is more that no more sensitivity is desirable.  相似文献

This clinically based study asked 165 batterers attending a court-mandated assessment program to quantify a series of behaviors that occurred since being convicted of battering. The behaviors clustered into 2 factors: (1) an Ambivalent Contact Pattern whereby behaviors of batterers were associated with contacting their ex-partner, sending gifts and letters, and watching her without her knowing while harboring conflicting feelings of love, hate, and anger; and (2) a Predatory Contact Pattern whereby the behaviors of batterers were associated with hang up calls, entering her home without permission, threatening or physically causing harm to her while harboring a propensity for abusiveness. Clinicians should assess batterers for predatory thoughts about the estranged partner, and reason for the contact since separation. Presence of stalking behaviors and predatory fantasy is a window to determine repetitive and escalating domestic violence.  相似文献

A 55-year-old male Caucasian truck driver was dead at the scene after breathing hydrogen sulfide (H(2)S) produced by an accidental transfer of sodium hydrogen sulfide (NaHS) from a tanker truck to a tank containing 4% sulfuric acid (H(2)SO(4)) and iron(II) sulfate (FeSO(4)). Autopsy of the decedent's body revealed pulmonary edema and passive congestion in lungs, spleen, kidneys, and adrenal glands. Postmortem biological samples were analyzed for carbon monoxide, cyanide, ethanol, and drugs. Since a potential exposure to H(2)S was involved, blood was also analyzed for sulfide (S(2-)). The analysis entailed isolating S(2-) from blood as H(2)S using 0.5M H(3)PO(4), trapping the gas in 0.1M NaOH, and determining the electromotive force using a sulfide ion specific electrode. Acetaminophen at a concentration of 14.3 microg/ml was found in blood, and metoprolol was detected in the blood, liver, and kidney samples. The blood S(2-) level was determined to be 1.68 microg/ml. It is concluded that the cause of death was H(2)S poisoning associated with a hazardous material accident in an industrial situation.  相似文献

It is well documented that labor force participation rates fell precipitately as the economies of the former Soviet Union and Central and Eastern Europe made the transition from plan to market. However data allowing for direct comparison between the planned and transition periods of specific countries is rare. Here comparable data is used examining labor force participation in the Baltic States in 1990 (the late Soviet period), 1996, and 1999. While the data do indicate large drops in labor force participation, much of the decrease was concentrated among older individuals (those over 55) and women.  相似文献

Estimating stature in human skeletal remains of Asian ancestry is problematic for forensic anthropologists due to the paucity and uncertain suitability of regression formulae. To address this issue, our study analyzed 64 individuals from a modern skeletal collection of South‐East Asian origin and developed population‐specific ordinary least squares regression formulae to estimate skeletal height from each of the long bones of the upper and lower limbs, as well as from trunk length. Results indicate that the most accurate estimates of skeletal height from a single bone (as measured by standard error of the estimate—SEE) are from tibial length in males (SEE = 2.40 cm) and from humeral length in females (SEE = 2.59 cm), followed by femoral length (SEE = 2.84 cm). When multiple elements are considered, the combination of femoral and tibial length yields the best estimates in both sexes as well as combined sex samples (male SEE = 2.40 cm; female SEE = 2.77 cm; combined sex SEE = 2.54 cm).  相似文献
