Understanding the Cultural Differences in Tourist Motivation Between Anglo-American and Japanese Tourists

Summary

There is considerable evidence to suggest that differences in cultural characteristics exist across the world. Among them, individualistic societies emphasize “I” consciousness, autonomy, emotional independence, pleasure seeking and universalism. On the other hand, col-lectivistic societies stress “we” consciousness, collective identity, group solidarity, sharing, and particularism. A comparative research on the motivation of tourists from different cultures may challenge current tourism research, which mainly focuses on individualism and rationalism. These values of individualism and rationalism result in underestimation of the influence of groups, norms, culture, and emotion or impulse on tourist behavior. There have been few studies which attempt to directly measure cultural characteristics and identity across culture, and to explain how these cultural characteristics play a role in creating distinctive differences in tourist motivation. Thus, this study explores (1) cultural differences underlying individualism-collectivism between Anglo-American and Japanese tourists; (2) examines the relationship of two cultural dimensions to tourist motivation, and (3) suggests management implications facing tourism industry.     

The rise and fall of single-letter ticker symbols

A single-letter stock ticker symbol is a limited resource – only 26 possibilities are available in a stock universe of over 475,000 possible one-, two-, three- or four-letter ticker symbols. These symbols were first allocated based on trading volume therefore some of the most important companies at the time were initially placed into this group. This paper examines the history of this group of stocks and documents a decline in the importance of these firms due to a natural turnover in commercial leadership and no established mechanism to remove the single-letter designation from firms that lost their prominence.     

十年反恐对美国及世界政治的影响

2011年5月1日基地组织头目本.拉登被美国击毙。从某种意义上说,这标志着美国十年反恐之路的终结。文章通过比较9.11事件前后的反恐战略来分析十年反恐给美国及世界政治造成的深刻影响。9.11前的美国反恐主要针对其认定的某些＂支恐＂国家。9.11事件发生后,恐怖主义是美国国家安全的最大威胁,美国出台了反恐战略,发动了阿富汗和伊拉克两场战争。美国反恐付出了巨大经济代价,使中东更加动荡不安,也给新兴发展国家提供了崛起的历史机遇。     

Perceived Value of Mexican vs. US Products in Mexico,Venezuela and the United States

Abstract

With the advent of NAFTA and the liberalization of Latin American markets, Mexican firms have gained new strategic options, many of which revolve around exporting regionally or to the United States and Canada. The studies explore consumer reactions to Mexican products. The first study compares value perceptions of a cross-national sample of Mexican, US and Venezuelan respondents toward US and Mexican products. It also explores the moderating effects of product content and financial risk on value differentials. The second study, limited to Mexican and Venezuelan respondents, looks for evidence of a home country bias. While the strategy implications for Mexican products differ according to a product's level of content and financial risk, the studies indicate that inter-regional trade is a viable possibility.     

Accounting for the Business of Suffering: A Study of the Antebellum Richmond, Virginia, Slave Trade

When the Congress barred the importation of slaves into the United States in 1808, it left the internal slave trade intact. The trade took on a new importance as the slave states of the Old South saw their agricultural economies shift to a point that holding large numbers of slaves became too expensive. During this time, the large agricultural concerns shifted to the New South, where cotton and sugar plantations needed the cheap labour provided by the institution of slavery. As this transition intensified, Richmond, Virginia, became a central slave market that facilitated the interstate slave trade as Old South planters chose the course of selling slaves as a valuable commodity rather than the course of manumission. The records of two businesses—Dickinson & Hill and Hector Davis & Company—which plied the slave trade in the Richmond market, have survived into the twenty-first century. These records revealed a primitive, yet sophisticated, process to account for the consignment, purchase, and sales of human merchandise in this haunting story of the 'business of suffering'.

The institutional ideas virus: the case of Johan Åkerman

Swedish economists have received impulses from historical or institutuionalist sources on many occasions. A couple of these economists, Gunnar Myrdal and Johan Åkerman, received obvious impulses from American institutionalism. This article deals with the case of Åkerman. To attempt a wall-to-wall chart of institutional influences on an economist is hardly possible. But what is possible is to examine occasions when he was exposed to powerful ‘jolts’, viz in conjunction with studies at an American university. Johan åkerman studied at Harvard in Cambridge in 1919–20. he evetually became – alongside Myrdal – the leading institutional economist.     

A transform approach to compute prices and Greeks of barrier options driven by a class of Lévy processes

In this paper we propose a transform method to compute the prices and Greeks of barrier options driven by a class of Lévy processes. We derive analytical expressions for the Laplace transforms in time of the prices and sensitivities of single barrier options in an exponential Lévy model with hyper-exponential jumps. Inversion of these single Laplace transforms yields rapid, accurate results. These results are employed to construct an approximation of the prices and sensitivities of barrier options in exponential generalized hyper-exponential Lévy models. The latter class includes many of the Lévy models employed in quantitative finance such as the variance gamma (VG), KoBoL, generalized hyperbolic, and the normal inverse Gaussian (NIG) models. Convergence of the approximating prices and sensitivities is proved. To provide a numerical illustration, this transform approach is compared with Monte Carlo simulation in cases where the driving process is a VG and a NIG Lévy process. Parameters are calibrated to Stoxx50E call options.
