红绿通道选择困境

世界海关组织在1999年6月修订的《关于简化和协调海关制度的国际公约》中建议：各国可在进境旅客携带应税商品进行海关申报方面使用红绿通道制度。根据该制度,进境旅客必须在红绿通道中选择一个,若携带应税商品,则应选择须完全申报并纳税的红色通道;若未携带应申报商品,则可选择绿色通道。     

A plausible model of yield curve dynamics

We present a simple model of yield curve dynamics which satisfies key criteria of plausibility. Specifically, yields are non-negative and the Sharpe ratio of a mean-variance optimal bond portfolio has a reasonable magnitude. The model matches stylized data features, in particular long-run moments of yields and excess returns.     

Expiration‐day effects on individual stocks and the overall market: Evidence from Taiwan

On expiration days of the MSCI‐TW index futures, the Taiwan spot market is associated with abnormally large volume and high index volatility, along with mild index reversal. The effects concentrate only in the last five minutes of expiration days and appear to be strengthened by the adoption a call auction closing procedure by the Taiwan Stock Exchange. Individual index stocks show high volatility and strong tendency of price reversal, with large‐ and small‐cap stocks being affected more than the medium‐sized stocks. The highest‐weighted stocks exhibit excessive volume and volatility, which is disproportionate to the impact on all other index stocks, indicating that the expiration‐day effects may have been amplified by the attempt of price manipulation using large‐cap stocks. © 2009 Wiley Periodicals, Inc.

Low-latency trading

We define low-latency activity as strategies that respond to market events in the millisecond environment, the hallmark of proprietary trading by high-frequency traders though it could include other algorithmic activity as well. We propose a new measure of low-latency activity to investigate the impact of high-frequency trading on the market environment. Our measure is highly correlated with NASDAQ-constructed estimates of high-frequency trading, but it can be computed from widely-available message data. We use this measure to study how low-latency activity affects market quality both during normal market conditions and during a period of declining prices and heightened economic uncertainty. Our analysis suggests that increased low-latency activity improves traditional market quality measures—decreasing spreads, increasing displayed depth in the limit order book, and lowering short-term volatility. Our findings suggest that given the current market structure for U.S. equities, increased low-latency activity need not work to the detriment of long-term investors.     

Individual and Group Behavior in the Ultimatum Game: Are Groups More “Rational” Players?

This article reports two experiments that compared the standard ultimatum game played by individuals with the same game played by three-person groups. In the group treatment, the members of the allocating group conducted a brief, face-to-face discussion in order to decide, as a group, on a proposed division, whereas the members of recipient group held a discussion on whether to accept or reject the proposal. If the proposal was accepted, each group member received an equal share of his group's payoff (the pie in the group condition was three times that in the individual condition). In both experiments, groups offered less than individuals. But as indicated by the low rejection rate in both treatments, groups were also willing to accept less.     

TECHNOLOGICAL LEARNING AND LABOR MARKET DYNAMICS

The search‐and‐matching model of the labor market fails to match two important business cycle facts: (i) a high volatility of unemployment relative to labor productivity, and (ii) a mild correlation between these two variables. We address these shortcomings by focusing on technological learning‐by‐doing: the notion that it takes workers' time using a technology before reaching their full productive potential with it. We consider a novel source of business cycles, namely, fluctuations in the speed of technological learning, and show that a search‐and‐matching model featuring such shocks can account for both facts. Moreover, our model provides a new interpretation of recently discussed “news shocks.”     

The search for authenticity in the pilgrim experience

The present study enriches the theoretical debate on the concept of authenticity by examining its relevance to the experiences of pilgrims. Overall, the study argues that the recent conceptual shift in the tourism literature, which tends to view authenticity in a subjective sense, should be rethought due to its lack of consideration of ideological and spatial dimensions. Employing data from fieldwork on fundamentalist Christian pilgrimages, the study integrates previous approaches to authenticity through a conceptual framework referred to as theoplacity.     

The Who,Where, What,How and When of Market Entry

This introductory, along with the eight articles contained within this Special Issue, highlights and brings greater clarity to entrant‐incumbent interactions and to firm movement – when entrants traverse market territories for the creation and/or delivery of offerings, where ‘markets’ include service or product categories, technology or resource spaces, industries, sectors and/or geographies. Collectively, this Special Issues explains that firm movement across market boundaries is highly consequential, influencing resource‐capability mixes inside firms, interfirm relations, market logic and industry value chains, and of course, people, communities and even nations. Specifically, we develop a field‐wide perspective of market entry by expanding on the framework of market entry that Zachary and his colleagues developed (Zachary et al., 2015) – i.e., the who (players such as incumbents, entrants, suppliers, etc.), when (the timing and sequence of entry), how (the strategy, resources, capabilities, etc.), where (the space of entry) and what (product, service, business model, etc.) – to include two additional categories: complements (networks, platforms, ecosystems) and non‐market elements (government, political, social and cultural arrangements). We also summarize the eight highly diverse and insightful articles that make this Special Issue, and conclude with a discussion to highlight foundational questions that point to new directions in future research in this field. In sum, we hope to inspire scholars to go beyond counting outcomes (e.g., entry/exit rates, or profiling successful versus unsuccessful entrants), to consider contexts, processes and contingencies (e.g., cost, time, collaboration, competition, interfirm relations, etc.) and to discover boundary conditions that inform a theory of market entry.     

Hotel workers’ substance use and abuse

This study investigates the usage of tobacco, alcohol, and cannabis among hotel employees in the resort city of Eilat. Data obtained from a sample of 458 respondents, drawn from three hotel chains, provides evidence of workers’ substance consumption in light of their socio-demographic backgrounds and specific job characteristics. The results indicate a higher rate of substance use among study participants in comparison to the average in Israeli society. Substance use was found to be the most prevalent among young, single male employees with relatively low levels of education. In terms of job characteristics, front-of-the-house employees were more prone to binge drinking than back-of-the house employees. It is suggested that work-related programs and policies, such as sensible drinking workshops and smoking cessation programs, may help prevent alcohol misuse and reduce extensive substance use among hotel staff.
