Sample bias in contingent valuation: A comparison of the correction methods

Abstract

This article compares various methods for correcting contingent valuation aggregate benefits when the sample is known to be biased. A sample is defined as the population, and response rates are simulated on the basis of a measure of salience. The simulated response rates suffer from nonresponse bias and selection bias. Coefficient and benefit estimates that result from weighting and self‐selection correction approaches are compared with the true coefficient and benefit estimates. Our results indicate that at both low and high response rates the standard approach leads to bias, and either correction approach will reduce the bias in coefficient and benefit estimates.     

Risk Perception and Buying Behavior: An Examination of Some Relationships in the Context of Cruise Tourism in Jamaica

Cruise tourism continues to grow substantially, even as many other forms of travel stagnate. In this era of increasing worldwide violence against tourists, safety, security, and risk abatement are becoming principal components in travelers' decision-making processes. This work examines the issue of perceived risk and safety and what impact these perceptions have on shopping behavior. The research takes place in Jamaica, a country with a reputation for aggressive vendors. Findings indicate that those visitors who traveled with others spent more time shopping and purchased more. Additionally, it was found that first time visitors express higher levels of discomfort with their surroundings than did repeat visitors, thus inhibiting purchase behavior. Finally, it was found that levels of perceived risk and security did have an impact on a traveler's intention to return to Jamaica.     

Bundling attractions for rural tourism development

Tourism is often regarded as a viable solution to economic crisis, especially for remote areas without many development options. While many tourism destinations have strong cultural or heritage assets, not all destinations have primary attractions that can bring visitors to the region. Rather than developing special interest “themes”, rural areas that do not have enough of any one type of tourism resource to act as a primary draw may consider bundling different attraction types to increase visitation. The purpose of this study is to investigate the preferences of visitors to secondary heritage sites and explore the relationship between heritage tourism and alternative, non-heritage activities in rural areas. Findings revealed that motivation to visit small-scale heritage sites consisted of two dimensions: learning and recreation. The two motivational dimensions influenced visitors’ interest in different heritage attractions and likelihood of visiting heritage tourism “scenarios”. As for alternative activities, there was a cluster of “popular” activities that were enjoyed by both learning-oriented and recreation-oriented respondents, but recreation-oriented visitors were more interested in nature-based activities and sport-related activities than learning-oriented visitors. Findings can help rural communities improve secondary attractions and diversify their tourism product by bundling heritage attractions with non-heritage activities.     

Plunging into the sea, again? A study of serial entrepreneurship in China

While it stands to reason that serial entrepreneurs—individuals who have founded more than one new venture—should achieve higher levels of success than novices, to date researchers have found little support for this proposition. Is this rather perplexing result only limited to the developed countries in which most research has been conducted? Or is it indicative of a general phenomenon, and hence requesting the need for new theory? We explore these questions by testing the existing theory in two geographic regions in a rapidly emerging transition economy—China. Data from 440 Chinese entrepreneurial ventures suggest that experienced entrepreneurs are better at developing networks, and at managing organizations than novices, but like their counterparts in developed countries, do not necessarily achieve higher levels of venture performance. Implications for theory, as well as for entrepreneurship in the context of transition economies are addressed.     

全球化：前景、潜力与问题

本文扼要阐述了经济全球化发展的前景和潜力,并运用李嘉图模型对全球化可能导致的经济损害作出论证分析进而说明,尽管经济学家在极大程度上趋向于将全球化视为基本良性的现象,但全球化仍然对某些国家（包括发达国家）带来经济损害,及对部分人群可能造成极其痛苦的后果。不过,源自于全球化的不断增长的竞争压力,会加强创新和增长,从长远来看,的确对每个国家有利。     

Demand for Customized Products, Production Flexibility, and Price Competition

We examine markets where, in addition to production of standard (core) products, mass customization is technologically feasible. We compare a setting where a monopolist provides both standard and custom goods to a setting where an entrant joins the custom market and find customers' tastes affect the social desirability of entry. The entrant is unconcerned about the impact of its custom production on the incumbent's core product market and in some cases may supply more custom products than is socially desirable. Entry enhances (reduces) social welfare if consumers' core valuations are positively (negatively) related to their value added for customization.     

The effects of interactive leadership on human resource management in Singapore's banking industry

Reviewing the literature about interactive leadership and its effects on human resource management in business organizations, this paper proposes that interactive leadership has two major components: interaction skills and team building. Both components have positive effects on employees' trust in their leaders, on employees' motivation and employees' commitment to their companies. Based on these hypotheses, the paper develops an empirical test of the effectiveness of interactive leadership in Singapore's banking industry. Seventy-seven middle-level managers participated in this study by responding to a questionnaire about their leaders, their motivation, their commitment and their trust in these leaders. The results support the hypotheses and suggest some important implications for human resource management in business organizations, especially for human resource management in Oriental societies.     

Banknotes And Economic Growth

Modern paper currency contributes little to productive investment. This shortcoming is not inherent to paper money. It stems from the fact that currency today is monopolistically supplied by public monetary authorities that are poor intermediaries. Commercial banknotes may, in contrast, support efficient intermediation, just as private bank deposits do. We demonstrate this advantage in an endogenous growth model, and use the model to simulate, for a sample of developing countries, steady‐state growth‐rate gains from various degrees of banknote deregulation. The simulated gains are generally large compared with those from conventional forms of financial liberalization.
