On the advantages of economically designed the Hotelling’s T2 control chart with variable sample sizes and sampling intervals

Faraz and Parsian (Statistical Paper, 47: 569–593, 2006) have shown that the double warning lines (DWL) scheme detects process shifts more quickly than the other variable ratio sampling schemes such as variable sample sizes (VSS), variable sampling intervals (VSI) and variable sample sizes and sampling intervals (VSSVSI). In this paper, the DWLT²control chart for monitoring the process mean vector is economically designed. The cost model proposed by Costa and Rahim (Journal of Applied Statistics, 28: 875–885, 2001) is used here and is minimized through a genetic algorithm (GA) approach. Then the effects of the model parameters on the chart parameters and resulting operating loss is studied and finally a comparison between all possible variable ratio sampling (VRS) schemes are made to choose the best option economically.     

Economic impact studies of Beijing 2008 Olympic Games

The paper provides an ex-ante analysis of the financial burden and potential economic benefit of the Beijing 2008 Olympic Games. Owing to the lack of uniform financial data, cost and benefits analysis is not possible, so we have adopted a multi-criteria analysis （MCA） as a part of an Olympic Games impact study, to asses the possible economic impact of hosting the Olympics in Beijing. There are many aspects of a country that may change as a result of hosting the Olympic Games. Studies on the impact of previous Olympic Games have indicated that inward investment has been attracted by preparations for the Olympics which has increased the host cities global profile and by the legacy of additional facilities afterward. Beijing is already an establish city and prime destination for inward investment in China and Asia. Hosting the Olympics in 2008 might be expected to give rise to tangible positive effects on the over all level of economic activities.     

The fifth development plan

The four development plans, under which Iran has gone forward on a continuous course of industrialization since 1949 were followed by a Fifth Development Plan, which came into force in March 1973. This fifth plan had however to be revised recently: the expenditure on investments is to be doubled compared with the original plan.     

The Determinants of Bank Capital Ratios in a Developing Economy

This paper reports new findings on the determinants of bank capital ratios. The results are from an unbalanced panel data set spanning eight years around the period of the 1997–1998 Asian financial crisis. Test results suggest a strong positive link between regulatory capital and bank management’s risk-taking behaviour. The risk-based capital standards of the regulators did not have an influence on how regulatory capital is adjusted by low-capitalized banks, perhaps due to the well-documented banking fragility during the test period. Finally, bank capital decisions seem not to be driven by bank profitability, which finding is inconsistent with developed country literature that has for long stressed the importance of banks’ earnings as driving capital ratios. Although the study focuses only on one developing economy, these findings may help to identify the correlates of bank capital ratios in both developed and developing economies since this topic has received scant attention of researchers. These findings are somewhat consistent with how banks engaging in risky lending across the world could have brought on the 2007–2008 banking liquidity and capital erosion crisis.     

A brand preference and repurchase intention model: the role of consumer experience

Consumer brand preference is an essential step towards understanding consumer choice behaviour, and has therefore always received great attention from marketers. However, the study of brand preference has been limited to traditional marketing focusing on functional attributes to maximise utility. But now the shift to experiential marketing broadens the role of the brand from a bundle of attributes to experiences. Technological advancements have helped to increase the similarities between brand attributes and product commoditisation. Consequently, consumers cannot shape their preferences among brands using rational attributes only. They seek out brands that create experiences; that intrigue them in a sensorial, emotional and creative way. This study seeks to develop a model that provides an understanding of how brand knowledge and brand experience determine brand preference and to investigate its impact on brand repurchase intention. Accordingly, exploratory focus group discussions are employed followed by a survey of mobile phone users in Egypt. The findings provide insights into the relative importance of consumer perceptions on different brand knowledge factors in shaping brand preferences. It also demonstrates the significance of consumers’ experiential responses towards brands in developing their brand preferences that in turn influence brand repurchase intention. The model therefore offers managers a new perspective for building strong brands able to gain consumer preferences.     

Corporate Debt Maturity Structure: The Role of Firm Level and Institutional Determinants in Selected African Countries

An appropriate debt maturity structure is essential for firms to enable them align asset structure to liabilities to prevent a mismatch. This study investigates the role of firm-level and institutional variables on debt maturity structure in selected African countries. Using panel generalised method of moment that addresses endogeneity problem; our findings reveal a dynamic process of adjustment to optimal debt maturity structure. Furthermore, firm-level variables (leverage, asset structure and firm size) provide support for the contracting cost, signalling and matching principle theories of debt maturity structure. Results of institutional variables suggest that better developed institutions promote long-term debt maturity structures.     

Poverty, Growth, and Redistribution: a Study of Iran

The paper examines changes in the extent of poverty in Iran in the period 1983 to 1993. More specifically, it investigates the contributions of growth and redistribution factors to changes in poverty over this period of ten years. The analysis is based on household‐level data relating to three Household Income and Expenditures Surveys of 1983, 1988, and 1993. The study reveals that the extent of poverty in the rural sector declined slightly, whereas in the urban sector it increased significantly. Decomposition of changes in poverty into growth and redistribution components indicates that in each sector the redistribution component was positive, implying that the deterioration of income inequality contributed to the worsening of poverty. The growth component, however, affected the two sectors differently: it contributed to a reduction in poverty in rural areas and an increase in urban areas.     

The structure of urban governance in South African cities

This paper analyzes the economic factors that will determine the evolution of the structure of urban governance in South Africa's major metropolitan areas. The paper suggests that fiscal autonomy, distributional, and efficiency considerations have supported a move toward a two-tier metropolitan structure. Within this two-tier system, fiscal stability considerations favor a model of functional fragmentation and privatization of municipal services. Two factors that have influenced the choice of urban governance are spatial policies of the apartheid regime and the uncertainty in the allocation of fiscal transfers between different tiers of government.     

Toward closer links between science and society in India: A futuristic formula

This work presents a futuristic scenario of science and technology in India in relation to development and social change. Organizational, financial, developmental, etc. trends in science and technology have been identified as consequences of history, culture and national policy alternatives conceived in the past and perceived for the future. The present course of action is considered unlikely to bridge the existing gap between science and society in India. The findings are relevant for S&T policy and planning in the developing countries.
