Ranked set sampling and randomized response procedures for estimating the mean of a sensitive quantitative character

This paper is devoted to the analysis of the estimation of the mean of a sensitive variable. The use of a randomized response (RR) procedure gives confidence to the interviewed that his privacy is protected. We consider that a simple random sampling with replacement design is used for selecting a sample. The behavior of the RR procedure, when ranked set sampling is the design used, is developed under three different ranking criteria. The usual gain in accuracy associated with the use of ranked set sampling is exhibited only by one of the designs. The behavior of the models is illustrated using data provided by a study of samples of persons infected with AIDS.     

Fees for Reefs: Economic Instruments to Protect Mexico’s Marine Natural Areas

Stated preference methods can be used to estimate the demand function where no price variation has been observed before. This is the situation of the Mexican coral reef natural protected areas, where after the 2002 approval of a $20 pesos fee (US$1.80) the Ministry of the Environment is now considering increasing the amount of the fee, not only to raise more revenue for the park, but also to curb the number of visitors in the cases where there is excess demand. There are concerns that the very success of the reefs is bringing associated environmental damage that threatens its sustainable use. To estimate the reaction of visitors to different fee levels, we carried out a contingent valuation survey, and constructed with its results an aggregate demand for each park. This demand was then divided by seasons and nationalities, to explore the benefits and costs of differentiating fees, looking at both the revenue maximising and the welfare maximising fees. Finally we discuss how these fees would change when environmental damage functions are taken into account. The recommendation is that increasing fees up to the point where they cover both private and environmental costs would bring the highest amount of economic benefit compatible with the sustainable use of these complex and wondrous marine ecosystems.     

Portuguese tour operators: A fight for survival

This article looks at the efficiency of Portuguese tour operators focusing on firm size, group ownership, and mergers and acquisitions. It has been argued that changed market conditions in Europe make it hard for tour operators to achieve economies of scale and market growth without increasing firm size or being part of a more high profile company.     

Are large portions always bad? Using the Delboeuf illusion on food packaging to nudge consumer behavior

Exaggerated portion sizes are generally pictured on the front of product packaging in order to stimulate food craving and encourage consumer purchasing decisions. However, one problem with such images is that they can set inappropriate norms as far as food consumption is concerned and hence result in people serving themselves more than they otherwise might. The research reported here builds on the fact that depicting a food portion in a smaller (vs. larger) container (i.e., plate or bowl) creates the illusion of a larger (vs. smaller) portion, although the actual quantity of food remains the same (this is known as the Delboeuf illusion). Here, we demonstrate in two experiments that by presenting food in a smaller container (thus giving rise to the illusion of a relatively larger portion), participants have higher purchase intentions (study 1) and perceive the food as being more appetizing (study 2) but, crucially, decrease the size of the portion that they serve themselves (studies 1 and 2). Overall, by giving the impression of a larger portion on product packaging, the Delboeuf illusion could potentially be used to nudge consumers to find food more desirable, while at the same time leading them to reduce their serving, thus potentially benefitting both consumers and the food industry.     

The Role of Informational and Congruence Clues in Advertisement for an Ethnic Restaurant

This study analyzes the effect of informational clues and Chef-Cuisine congruence, and their relation to advertisements for a Japanese restaurant. Two experiments were conducted with 171 consumers. Findings supported the following: Congruence between a Japanese restaurant and Japanese Chef results in higher approval ratings than the combination of Japanese restaurant with Brazilian Chef. However, if the advertisement states that the restaurant has won an award, then Chef-restaurant congruence is no longer an important factor in consumers’ evaluations.     

The ‘disguised’ foreign investor: Brands,trademarks and the British expatriate entrepreneur in Brazil

Abstract

This article examines the impact of the British expatriate entrepreneur, and his processes of knowledge transfer, on the industrialization and economic development of Brazil between 1875 and 1914. It focuses on the textiles industry, and combines original trademark data with conventional trade and investment statistics, and also case study analysis about firms and their entrepreneurs. It argues that British investment in Brazil was higher and had a deeper impact on economic development than considered by existing research, as expatriate entrepreneurs ‘disguised’ a substantial amount of foreign investments by acting as shareholders and top managers of newly established local businesses.     

Assessing the needs of international markets against an emerging market company's capabilities: A tool for internationalization

Senior managers in emerging markets often strive to ensure that their companies develop sufficient capabilities to confront the needs they encounter in international markets. However, extant research and practice remain unclear as to how senior managers in emerging market companies can approach assessing the needs of their international markets against their own company's capabilities, to aim for a balance between both. This article offers an innovative approach for assessing the needs of international markets against an emerging market company's capabilities. Based on the assessments of 100 senior managers leading emerging market companies, we explain how this approach can provide two key insights. First, evidence of a balance between the needs of international markets and an emerging market company's capabilities, that indicates the company's competitive position is focused; or evidence of an imbalance between the needs of international markets and an emerging market company's capabilities, that indicates the company's competitive position is either vulnerable or overqualified. Second, an understanding of where the gaps between the needs of international markets and an emerging market company's capabilities are, that enables improving the company's competitive position by closing these gaps. Drawing on this approach, we offer an open access tool that allows senior managers in emerging markets to identify and improve their own company's competitive position for internationalization. Using this tool, senior managers can lead their emerging market companies toward a focused competitive position in international markets, providing better chances of successfully capturing potential benefits.     

Export market re-entry: Time-out period and price/quality dynamisms

The relevance of nonlinear internationalisation regarding exporting activities and the performance post re-entry remains little understood. This study develops a two-stage model to explain the process of exporting firms’ exit and re-entry decisions regarding individual export markets. Specifically, it investigates the dynamic relationships between exit and re-entry stages by focusing on the time-out period. This study empirically tests the decision model by employing export data from the Chinese Customs for the period 2000-2009. The results indicate the importance of the exit stage in shaping re-entry decisions, price/quality ratio and export performance, where time-out period plays a significant role in varying these effects.     

Consumption as a social integration strategy in times of crisis: The case of vulnerable households

In this article, we focus on consumption in a context of economic hardship. From an empirical perspective, and using a qualitative methodology, we show how disadvantaged individuals and households maintain a level of consumption commensurate with the society in which they are integrated through a type of consumption conceived of here as “resilient”. Resilient consumption is characterized by being a type of expenditure oriented towards maintaining the role of consumer, that is, maintaining a minimum level of purchasing power, modifying to this end both the level and the structure of consumption, both of which are key elements in the resilience process. We identify five main strategies used by households that modify and restructure the consumption of basic goods and necessities in response to economic hardship. Key resilient consumption strategies include: reduction (cutting down on spending), substitution (replacement of one difficulty with another), compensation (pseudo‐consumption or reduced usage), transference (meta‐resilience) and integration (reinterpretation of difficulties as opportunities). We conclude that although consumption is a naturally resilient behaviour, in a crisis context, resilient practices focus on maintaining acquisition capacity in spite of reduced income.     

Increasing a brand’s competitive clout: the role of market share,consumer preference,and price sensitivity

The market power (or ‘competitive clout’) of a brand is an increasingly important component of modern marketing strategies. However, the factors that enhance a brand’s competitive clout (BCC) are poorly understood. This study therefore suggests an integrated model of BCC and three factors that are proposed to play a role in its formation: (i) consumer price sensitivity; (ii) brand market share; and (iii) consumer brand preferences. These variables are examined both individually and simultaneously to demonstrate the direct effect of each on BCC and how their inter-relationships contribute to BCC. In doing so, a two-step empirical analysis is conducted. First, two multinomial logit models provide an own- and a cross-price response matrix for a chosen set of competitive brands. Secondly, BCC is regressed against the variables of market share, intrinsic preferences, and price sensitivity using an interaction effects regression model. The results of the analysis show that market share is not the only way to increase BCC; in particular, consumer preferences, and especially pricing decisions, are shown to play a key role in developing a strong brand.
