Hard‐to‐Solve Bimatrix Games

The Lemke–Howson algorithm is the classical method for finding one Nash equilibrium of a bimatrix game. This paper presents a class of square bimatrix games for which this algorithm takes, even in the best case, an exponential number of steps in the dimension d of the game. Using polytope theory, the games are constructed using pairs of dual cyclic polytopes with 2d suitably labeled facets in d‐space. The construction is extended to nonsquare games where, in addition to exponentially long Lemke–Howson computations, finding an equilibrium by support enumeration takes on average exponential time.     

A WHITER SHADE OF PALE: ON THE POLITICAL ECONOMY OF REGULATORY INSTRUMENTS

We consider an intertemporal policy game between changing governments that differ in their attitudes towards a particular feature of market outcomes, exemplified with environmental pollution. When in power, a government will choose policy instruments and set strictness of regulation with a view to influencing the policy of future, possibly different, governments. We demonstrate that a “brown” government favours emission quotas over effluent taxes, as quotas establish property rights that are costly to reverse. Conversely, a “green” government prefers to regulate by taxes, in order to limit the incentives of future brown governments to ease regulations. Strategic behaviour tends to exaggerate policy differences (making green governments greener and brown governments browner) compared to when such strategic considerations were not an issue.

A Risk and Economic Analysis of Dirty Bomb Attacks on the Ports of Los Angeles and Long Beach

This article analyzes possible terrorist attacks on the ports of Los Angeles and Long Beach using a radiological dispersal device (RDD, also known as a "dirty bomb") to shut down port operations and cause substantial economic and psychological impacts. The analysis is an exploratory investigation of a combination of several risk analysis tools, including scenario generation and pruning, project risk analysis, direct consequence modeling, and indirect economic impact assessment. We examined 36 attack scenarios and reduced them to two plausible or likely scenarios using qualitative judgments. For these two scenarios, we conducted a project risk analysis to understand the tasks terrorists need to perform to carry out the attacks and to determine the likelihood of the project's success. The consequences of a successful attack are described in terms of a radiological plume model and resulting human health and economic impacts. Initial findings suggest that the chances of a successful dirty bomb attack are about 10-40% and that high radiological doses are confined to a relatively small area, limiting health effects to tens or at most hundreds of latent cancers, even with a major release. However, the economic consequences from a shutdown of the harbors due to the contamination could result in significant losses in the tens of billions of dollars, including the decontamination costs and the indirect economic impacts due to the port shutdown. The implications for countering a dirty bomb attack, including the protection of the radiological sources and intercepting an ongoing dirty bomb attack are discussed.     

Brand management: Unveiling the delusion of control

Mainstream brand management literature views brands as products or organisations carrying brand names and brand managers as being in control of brand-related actions and outcomes. By contrast, recent empirical research shows the substantial influence of stakeholders on brands. Together with brand management, stakeholders shape brands by participating in brand-related interaction. European brand research accordingly treats brands as ongoing and complex processes in constant flux. Nevertheless, literature suffers from a significant lack of theoretical underpinnings for understanding brands as complex processes; in this respect, building on European philosophy is a fruitful avenue. This paper introduces the metaphor of the rhizome and draws on European process philosophy to further develop an integrative processual understanding of brands. Brand management claiming control over brands as processes turns out to be a delusion.

The role of management attorneys in union organizing campaigns

We examine the role and effect of management attorneys in union organizing campaigns by conducting in-depth interviews with a number of management and union attorneys, union organizers, and NLRB administrators. Hypotheses are developed for future empirical testing.     

Stress in two-generation farm and ranch families

Family relations and economic issues may predict stress in two-generation farm families. Marital adjustment, length of time married, income satisfaction, and number of household dependents are examined as predictors of stress for each family member (i.e., separately for each member) using multiple regression analyses. The model is significant for fathers with marital adjustment, length of time married, and income satisfaction significantly contributing to fathers' stress. The model is not significant for mothers, sons, or daughters-in-law; but income satisfaction is significantly related to stress for mothers. Implications for researchers and practitioners are discussed.Support for this research was provided by the Montana Agricultural Experiment Station Grant No. MONB00266 and is part of the AES Western Regional Project W-167.Stephan M.

Ethnic Identity Among Mixed-Heritage People In Hawaii

In this study, intensive interviews were used to explore the identity of a sample of mixed-heritage Hawaiin college students from a variety of ethnic groups. The great majority of respondents listed at least one multiple-heritage identity (e.g., Chinese-Japanese). While cultural exposure and ethnic identity were strongly associated, cultural exposure is neither a necessary nor a sufficient condition for ethnic identity to occur. Differences in perceptions of ethnic identity between respondents with stable and situtionally changing identities were discussed. The conceptions of identity proposed by processual and structural symbolic interactionists both received some support in these data.
