In mixed strategy games, the ability to randomize decisions is a critical strategic necessity, yet studies show that such rational behavior is sometimes elusive. This paper examines mixed strategy play in a natural setting, by looking at a pitcher’s decision to throw the ball to home plate or to throw it to first base in a pickoff play. In the absence of significant pressure, we find that pitchers can effectively randomize their sequence of choices to remain unpredictable, as mixed strategy Nash equilibriums require. However, in the face of pressure, some pitchers are less able to randomize their choices. Our paper is the first empirical study in the English language literature to find that decision makers are unable to randomize their strategic decisions when they face an increased cognitive load due to pressure.
This paper investigates the pattern of inbound tourists' consumption in South Africa, examining four main intercontinental markets and five different tourism goods. The empirical investigation develops an almost ideal demand system (AIDS) model and it extends recent research by allowing tourists to base their spending decision on the real effective price differences between South Africa and their home country. The results show that tourist spending in South Africa is a luxury good, and tourists react normally to a change in the relative price of goods. The cross‐price elasticities suggest that the preferences of different markets influence their view of substitutability and complementary effects between various products in South Africa. 相似文献
Education-job mismatches are reported to have serious effectson wages and other labour market outcomes. Such results areoften cited in support of assignment theory, but can also beexplained by institutional and human capital models. To testthe assignment explanation, we examine the relation betweeneducational mismatches and skill mismatches. In line with earlierresearch, educational mismatches affect wages strongly. Contraryto the assumptions of assignment theory, this effect is notexplained by skill mismatches. Conversely, skill mismatchesare much better predictors of job satisfaction and on-the-jobsearch than are educational mismatches. 相似文献
The situation in the Middle East has developed through an episodic process in which the protagonists have periodically changed the ‘game’ that they are playing by inventing new options, seeking to eliminate the options available to others, or by raising or eliminating doubts in the minds of others about their intentions. Such conflict evolution is readily captured by the framework of drama theory which goes some way to explaining the pressures motivating such actions. This paper traces the recent development of relations between the Israelis and the Palestinians through a succession of drama theoretic models. The importance of taking note of interactions at several levels is highlighted: stalemate at one level may be dislodged by actions taken in others. It is concluded that any resolution of the confrontations in the Middle East is likely to require the active involvement of the international community but may be destabilised by pressure from internal factions within the key parties. 相似文献
Personal presentation attributes have long been understood to affect perceptions of competence and capabilities. To that end, this study investigates seven attributes associated with favorable interview presentation, including overall physical attractiveness, neatness and grooming, clothing color, conservative versus trendy attire, professional versus casual attire, and body modification (including tattoos and piercings). Participants (n = 108), including students, faculty, and hospitality industry professionals, sorted an orthogonal array of 16 full-color, laminated cards that contained photos so that respondents could see levels of clothing color, clothing conservativeness, and degree of professional attire. The remaining attributes and their corresponding levels were shown on respective analog indicators. The conjoint analysis results indicate that grooming and professional attire are the most important attributes in shaping favorable perceptions. Furthermore, faculty perceived conservative clothing to be better while students and industry professionals indicated that trendy clothing creates a more favorable presentation on the part of a job candidate. 相似文献
We examine the relation between corporate liquidity and political connections measured via lobbying expenditures. This is an interesting question as many of the motives for holding cash should be diminished by political connections. Results indicate a significant and inverse relation between cash levels and lobby expenses and that the marginal value of cash decreases with lobbying. Taken together, these findings suggest firms react optimally to the reduced benefits of cash linked to political connections and that the market recognizes the weakened benefits of cash. Overall, our research shows another way political connections can shape corporate policy. 相似文献
