Excess Capacity and Asymmetric Information in Developing Country Fisheries: The Malaysian Purse Seine Fishery

Excess capacity poses a problem in many developing country fisheries. These countries often pursue a development strategy aimed at expanding capacity under open access. Sustainable development, however, requires management. Principal-agent issues from asymmetric information between the regulator and fishers, which potentially form serious obstacles to fisheries management, arise in the likely forms of management. This article discusses principal-agent issues and examines the principal-agent moral hazard issue, which is due to divorce of ownership and vessel operations. The article also illustrates a method for estimating capacity when information is limited. The Peninsular Malaysian purse seine fishery forms a case study.     

Risk and return in the Tehran stock exchange

This paper analyzes market index returns in the Tehran stock exchange (TSE) within the context of three variants of the Capital Asset Pricing Model: the static international; the constant-parameter intertemporal; and a Markov-switching intertemporal CAPM, which allows for time-varying degree of integration with regional and international equity markets. We find that TSE returns are CAPM-efficient at monthly frequency with respect to several international market indices. Moreover, we find evidence in support of international integration of the TSE with respect to international markets. In addition, we conduct an extensive investigation for the direction of causality between TSE returns, international market index returns, and those in neighboring countries.     

A process control method based on five-parameter generalized lambda distribution

The use of control charts in statistical quality control, which are statistical measures of quality limits, is based on several assumptions. For instance, the process output distribution is assumed to follow a specified probability distribution (normal for continuous measurements and binomial or Poisson for attribute data) and the process supposed to be for large production runs. These assumptions are not always fulfilled in practice. This paper focuses on the problem when the process monitored has an output which has unknown distribution, or/and when the production run is short. The five-parameter generalized lambda distributions (GLD) which are subject to estimating data distributions, as a very flexible family of statistical distributions is presented and proposed as the base of control parameters estimation. The proposed chart is of the Shewhart type and simple equations are proposed for calculating the lower and upper control limits (LCL and UCL) for unknown distribution type of data. When the underlying distribution cannot be modeled sufficiently accurately, the presented control chart comes into the picture. We develop a computationally efficient method for accurate calculations of the control limits. As the vital measure of performance of SPC methods, we compute ARL’s and compare them to show the explicit excellence of the proposed method.     

Consumers’ Preference Mapping and Their Behavior with Regard to Traditional Halwa Using a Structured Survey Questionnaire

In this study, a structured survey questionnaire was used to determine consumers’ preferences and their behavior with regard to halwa. Five types of consumer groups were identified thorough hierarchical cluster analysis based on ranked attributes. Color was ranked within the top three attributes for all the groups. In general, color, sweetness, appearance, and solubility were found to be the most important attributes for selecting the halwa. Five types of groups were identified based on their preference levels (i.e., intensity) of attributes. These could be recognized in terms of preferences for halwa with (1) black with high sweetness, (2) dark-brown with high-medium sweetness, (3) dark with low-medium sweetness, (4) brown with medium sweetness, and (5) dark with high-medium sweetness preferred consumers. The consumer segmentations identified could be used to develop retail marketing strategies and to develop store brands of diversified Arabian sweets and intermediate moisture fruit snacks, such as dates.     

Promoting Products Through Volume Discount: Evidence from Malaysia

ABSTRACT

This study examines the effectiveness of the determinants that influence consumers' intention to purchase products under volume discount scheme (VDS). In addition, the moderating role of age is tested. A pilot study of 259 consumers was performed to conceptualize the underlying constructs and identify questionnaire items through employing exploratory data analysis. This was followed by a comprehensive survey of 583 Malaysian consumers. Data were analysed using partial least squares technique. The results indicate that brand image, store image, message framing, product characteristics, scheme characteristics, and subjective norms are crucial factors for the successful implementation of VDS. There is a wide gap noted between young and mature consumers in terms of the factors that influence on their purchasing behavior under VDS. The results help retailers to promote products under VDS in an effective way.     

Internationalizing Business Education in Latin America: Issues and Challenges

This article examines the extent of internationalization of business education in Latin America and identifies the key challenges facing the Latin American business schools. Based on a survey of the business schools that are members of CLADEA (Consejo Latinoamericano de Escuelas de Administracion—Latin American Council of Management Schools), and also from available information from various public sources and the literature, this study finds that most Latin American universities recognize the importance of internationalization of curricula and have undertaken measures to provide a business education that creates a global awareness among students and sensitizes them to differences across countries. The study also identifies the areas that need further attention and resources for widening the extent of internationalization of business education in Latin America and recommends ways to address these challenges.     

The effect of communication design and recipients’ numeracy on responses to UXO risk

Risk communications aim to affect recipients’ understanding of specific risks, their trust and liking of the materials, affective responses, and associated behaviors. We developed communications about the number of construction workers expected to get hurt if building were permitted at the former Fort Ord weapons training site in California, despite its contamination with unexploded ordnance (UXO). We created eight versions, which presented text only or bar graph with text, the numerator of the risk (the number of workers expected to be hurt) with or without emphasis on the denominator (the total number of workers), and uncertainty information (the probability that different numbers of workers would be hurt) or not. Recipients varied in numeracy. We examined the effect of these communication features on recipients’ (1) understanding, (2) trust and liking of the materials, (3) affective responses, and (4) support for construction and for construction workers if construction were to be implemented. Low-numerate individuals showed less understanding across all versions of the communication, yet preferred graph-with-text displays relatively more than text-only displays as compared to high-numerate individuals. Emphasizing the denominator increased understanding of text-only displays but decreased support for construction and construction workers for all communication versions. Moreover, recipients were more supportive of construction and construction workers after receiving text-only displays without uncertainty information or graph-with-text displays with uncertainty information, seemingly due to communications with those features being trusted and liked more. We discuss the implications for communicating risks in general and for communicating UXO-related risks to the community surrounding Fort Ord.     

The Time Cost of Documents to Trade

The article shows that the number of documents required to export and import tend to increase the time cost of shipments. However, the increase in the time cost of increased documentation is much larger for countries that are relatively poor and large in size. One interpretation here is that the relatively rich countries that have more resources and the relatively small countries that rely more on trade invest more in building efficient documentation systems. Our findings suggest caution in interpreting how input-based measures, such as the number of required documents to trade, affect outcome measures.     

An assessment of the impact of watershed programmes on agricultural sustainability in Hamedan province,Iran

This paper assessed the effects of watershed programmes (WPs) on the sustainability of agro-ecosystems in Hamedan province, western Iran. This research was a causal–comparative study, and various techniques were used to collect data, such as survey data, archival data, observations, and face-to-face interviews with key informants. The causal–comparative method requires a comparison of agro-ecosystems with and without WPs. Therefore, a survey was conducted using a stratified random sampling to select 136 households in agro-ecosystems with and without WPs. Nine indicators were selected to evaluate sustainability. Significant differences were found between the two agro-ecosystems in biodiversity, soil quality management, hydrological processes, energy-use efficiency (EUE), access to public services, farm management practices, and social capital. No significant variation was found in the indicator of quality of life, even though that indicator was found to be slightly higher in the agro-ecosystem that had WPs. Results revealed that the agro-ecosystem with WPs, with the exception of the social capital, productivity, biodiversity, soil quality, EUE, farm management, and hydrological processes as well as access to public services had significantly higher values than the agro-ecosystem without WPs. Therefore, it can be concluded that despite WPs' positive impact on biodiversity, soil quality, hydrological processes, EUE, farm management, productivity, and access to public services, it had a negative impact on social capital. The findings suggest that WPs affected the agro-ecosystem by increasing the stability and economic viability of the agro-ecosystem and decreasing social dimensions. A new approach, including demand-driven WPs rather than supply-driven ones to cater to the specific needs of local people, was recommended for the promotion of the social acceptability of WPs.
