One-sample tests for a generalized Fréchet variance of a fuzzy random variable

A procedure to test hypotheses about the population variance of a fuzzy random variable is analyzed. The procedure is based on the theory of UH-statistics. The variance is defined in terms of a general metric to quantify the variability of the fuzzy values about its (fuzzy) mean. An asymptotic one-sample test in a wide setting is developed and a bootstrap test, which is more suitable for small and moderate sample sizes, is also studied. Moreover, the power function of the asymptotic procedure through local alternatives is analyzed. Some simulations showing the empirical behavior and consistency of both tests are carried out. Finally, some illustrative examples of the practical application of the proposed tests are presented.     

Determinants of vertical integration in export processing: Theory and evidence from China

This paper examines the determinants of vertical integration versus outsourcing in export processing, by exploiting the coexistence of two export processing regimes in China, which designate by law who owns and controls the imported components. Based on a variant of the Antràs-Helpman (2004) model, we show theoretically that control over imported components for assembly can affect firm integration decisions. Our empirical results show that when Chinese plants control the use of components, the export share of foreign-owned plants is positively correlated with the intensity of inputs provided by the headquarter (capital, skill, and R&D). These results are consistent with the property-rights theory of intra-firm trade. However, when foreign firms own and control the components, there is no evidence of a positive relationship between the intensity of headquarters' inputs and the prevalence of vertical integration. The results are consistent with our model that considers control over imported components as an alternative to asset ownership to alleviate hold-up by export-processing plants.     

Pop‐management literature: popular business press and management culture in Brazil

As in other emerging countries, the 1990s in Brazil were characterized by profound economic changes. The business press reflected and influenced this process. Newspapers and magazines grew and assumed an important role, disseminating values associated with neoliberalism and managerialism. In this paper, we aim to contribute to the understanding of the content produced by this media and how the readership reacts to this content. To accomplish these objectives, we used the method of fantasy theme analysis (Bormann, 1972) to analyze four business magazines, and we discuss how Brazilian culture mediates the assimilation of foreign ideas and managerial expertise. Our study also helps to understand how the pop‐management literature, disseminated by the business press, echoes and reinforces managerialism and management culture. Copyright © 2008 ASAC.

A look for low season tourist profile: Antalya Region of Turkey example

This paper investigates the profile of low season tourists who visit Antalya Region of Turkey. The research findings belong to their opinions regarding destination and quality of services. At the same time additional information on demographic aspects of sampled tourists can be followed from the research. In order to satisfy tourists, providing information about their likes and dislikes is always important. Primary goal of this paper is to be a potential part of future marketing strategy for Antalya Region. Ana Cristina N. Silva was an “Erasmus Student”.     

Exploring the Relationship between Sustainability Reporting and Sustainability Management Practices

There has been a dramatic uptake of sustainability reporting (SR) and sustainability management practices over the last two decades, in turn raising questions about the relationship between external disclosure and internal practice of corporate sustainability. Previous literature has emphasized the role of external pressures in driving SR adoption. However, as recent practitioner surveys also identify the existence of internal motives for SR, a more comprehensive analysis of this relationship is needed. In order to address this issue, we develop a framework accounting for four company‐level SR configurations, resulting from different levels of importance of external and internal motives for SR. Then, four exploratory cases serve to illustrate these configurations and to describe the respective roles of SR at the company level. As considerable diversity among these SR practices is found, our findings point to the relevance of both external and internal motives in understanding SR contribution to corporate sustainability.

Child labor and schooling response to changes in coca production in rural Peru

Coca eradication and interdiction are the most common policies aimed at reducing the production and distribution of cocaine in the Andes, but little is know about their impact on households. This paper uses the shift in the production of coca leaves from Peru to Colombia in 1995 to analyze the indirect effects of the anti-coca policy on children's allocation of time. After different sensitivity checks, the results indicate that a decrease in coca production is associated with increases in work and hours children living in coca-growing states devote to work within and outside the household, with no effects on schooling outcomes. These findings suggest a previously undocumented indirect effect of drug policies on household behavior.     

Forecasting US output growth using leading indicators: an appraisal using MIDAS models

We evaluate the predictive power of leading indicators for output growth at horizons up to 1 year. We use the MIDAS regression approach as this allows us to combine multiple individual leading indicators in a parsimonious way and to directly exploit the information content of the monthly series to predict quarterly output growth. When we use real‐time vintage data, the indicators are found to have significant predictive ability, and this is further enhanced by the use of monthly data on the quarter at the time the forecast is made.

Getting fourteen for the price of one! Understanding the factors that influence land value and how they affect biodiversity conservation in central Brazil

Biodiversity policies are suffering an implementation crisis; the roots are deeply entrenched in the unfair competition between the public and private interests for suitable versus available land. In this article we propose a value-based equivalence method for compensation for the 20% compulsory reserves in the Taquari River sub-catchments, as legally required for central savannas of Brazil. Using regression techniques we analyzed 106 land deals in the Pantanal's watershed and identified the most significant variables influencing land value. We argue that the commonly used area-for-area, compensation mechanism, where 1 ha of compulsory reserve is missing, requires another hectare protected in the same catchments, instead of counteract habitat loss, is in fact harmful to biodiversity, stimulating progressive habitat destruction. We identified the economic forces behind deforestation and habitat fragmentation in the central savannahs of Brazil and proposed a market-based approach to counteract these forces using tools already available in environmental economics. We suggest that a dollar-for-dollar reference to determine land equivalence and compensation can better counter-balance the incremental losses from habitat destruction, while providing objectivity and transparency for trading alternatives.
