Optimum allocation in multivariate stratified random sampling with overhead cost

The problem of allocating the sample numbers to the strata in multivariate stratified surveys, where, apart from the cost involved in enumerating the selected individuals in the sample, there is an overhead cost associated with each stratum, has been formulated as a non-linear programming problem. The variances of the posterior distributions of the means of various characters are put to restraints and the total cost is minimized. The main problem is broken into subproblems for each of which the objective function turns out to be convex. When the number of subproblems happens to be large an approach has been indicated for obtaining an approximate solution by solving only a small number of subproblems.     

Determinants of corporate social disclosure: Empirical evidence from Bangladesh

We explore the potential firm and industry characteristics that determine the corporate social responsibility (CSR) disclosure practises by Bangladeshi listed firms. We use a CSR disclosure checklist to measure the extent of CSR disclosure in the annual reports and a multiple regression analysis to examine the determinants of CSR disclosure. Our study finds that CSR disclosure has positive and significant relationships with export-oriented sector, firm size and types of industries. We also find a negative relationship between CSR disclosure and family ownership. The overall findings of our study provide empirical evidence which suggests that a number of firm and industry characteristics are important determinants of the extent of CSR disclosures in a developing country like Bangladesh. Our findings can help the policy makers to adopt necessary regulatory reform to improve the CSR practises and enhance organisational legitimacy.     

Innovation and Growth: A Schumpeterian Model of Innovation Applied to Taiwan

Following Schumpeter, we assume that innovation in specific firms, or groups of firms, can have economy-wide effects. Models based on this idea can be shown to have multiple equilibria. The idea of a positive feedback loop innovation system, or POLIS, is formalized by picking an appropriate sequence of equilibria over time. It is shown that POLIS has empirical relevance by applying the formal model to an actual economy. The 1997-98 financial crisis in many Asian countries, most notably South Korea, seemed to have reversed the conventional wisdom regarding the "East Asian miracle". This paper applies the concept of a POLIS to the case of Taiwan to show that, at least in this case, neither the view that the miracle was a mirage nor the view that the growth was a result of factor accumulation only is correct. Ultimately, technological transformation--in particular the creation of a positive feedback loop innovation system--is what makes the difference between sustained growth and gradual or sudden decline. Although problems remain in both the real and the financial sectors, the successes of Taiwan in building the preconditions for an innovation system are worth examining. Upon careful examination of Taiwan's system of innovation within the above Schumpeterian model it is found that Taiwan has a fighting chance of building a POLIS in the near future.     

Agricultural taxation in developing countries: a survey of issues and policy

This study surveys the experience of agricultural taxation in developing countries in the context of the ongoing policy debate about the tax structure and administration affecting agricultural producers. Using the examples of a number of countries, it analyzes the conceptual and practical problems associated with different tax regimes. Governments in most countries have reduced indirect (export) taxes on agricultural producers. However, the revenue from direct taxes on farmers has not increased. A major problem in most countries has been the measurement of (actual) agricultural income. Different measures for presumed income have been used with varying success. They seem to have the most potential for increased revenue in many countries, but their effective implementation is constrained by the political and administrative considerations.     

Can financial literacy reduce anxiety about life in old age?

This study examines the role of financial literacy in reducing anxiety about life in old age. We hypothesize that financial literacy increases preparedness for old age through better savings and investment decisions, leading to the accumulation of more assets and earning more income, which enhances financial capacity and reduces anxiety. Using data from a nationwide panel survey in Japan, we provide evidence that financial literacy can reduce anxiety about life in old age by making people capable of accumulating more assets and earning more income. Moreover, the interaction of financial literacy with age and spouse reduces anxiety, while living with children increases anxiety about life during old age. We check the robustness of our results using an alternative measure of financial literacy, changing composition of the sample, controlling for residents’ geographical dispersion, and testing for endogeneity bias. The major findings remain unchanged after considering these factors.     

Gender discrimination in education,health, and labour market: a voice for equality

The objective of the study is to examine the impact of gender discrimination in education, health, and labour market on economic growth in a panel of 20 high-income OECD countries for the period of 1980–2015. In addition, the study proposed an index of pro-equality growth, which is flared with education, health, and labour market initiatives to promote economic growth. The results show that gender parity index for educational attainment significantly promotes economic growth while health and labour market required substantial policy reforms to reduce health and labour market inequalities to sustain long-term economic growth. The results classified three countries as highly equitable growth, one country for equitable growth, two countries are moderate growth, four countries are less equitable growth while remaining 10 countries fall in the category of inequitable growth, where greater inequality promotes economic growth on the cost of education, health, and labour market inequalities.     

A review of the extensions of a modified EOQ model for imperfect quality items

Imperfect items in the raw material and production stages of a supply chain directly impact the coordination of the product flow within a supply chain. In response to this concern, production and inventory lot sizing models, which incorporate imperfect items into their formulation have become an important and growing area of research. The contribution of Salameh and Jaber (2000) is one of the fundamental models on lot sizing when procured items are of imperfect quality. Over the past decade, there has been a noticeable amount of interest in the EOQ model for imperfect items that was set forth in Salameh and Jaber (2000). Several researchers have published adaptations and extensions of this original model that address supply chain coordination, quality improvement and yield management, and the impact of human error on production and inventory systems. In this paper, we summarize the current body of research that has extended the Salameh and Jaber (2000) EOQ model for imperfect items. Some possible future research directions are identified at the end of the paper.     

Past,present, and future of green product innovation

Firms are under constant pressure from various governmental and nongovernmental agencies to switch from conventional environmentally polluting products to green product innovations (GPIs). However, the relevant research pertaining to GPI has been published in a diverse set of journals that vary in their scope and readership and, therefore, the scholarly contribution to the topic remains largely fragmented. This study has utilised a systematic literature review approach to examine the literary corpus on GPI to paint a holistic picture of its different aspects. The content and thematic analysis of 85 studies resulted in the extraction of seven key research themes: organisational capabilities, organisational learning, institutional pressures, barriers, structural changes, benefits of GPI, and methodological choices. This study's findings further highlight the various gaps in the GPI literature and raise some research questions that warrant scholarly investigation in the future. Likewise, our study has important implications for practitioners who are likely to benefit from a holistic understanding of the different aspects of GPI. Similarly, policymakers can use this study's findings to introduce policy interventions, especially in countries where GPI adoption is low.     

Optimum allocation in Bayesian stratified two-phase sampling when there arem-attributes

The problem of optimally allocating a sample amongk-strata at the second phase of a two-phase sampling procedure when the sampling is for proportion has been discussed byNewbold [1971] and then by the author [Khan, 1972].This paper deals with optimum allocation of the sample amongk-strata at the second phase of a two-phase sampling procedure, when the sampling is form-attributes. The problem is to estimate the proportion of each attribute in the population. Here (m–1) dimensional Dirichlet distribution is taken as the prior distribution.
