Socio-economic characteristics and the effect of taxation as a health policy instrument

This paper analyses the quantitative effects of using economic instruments in health policy on the basis of price elasticities calculated from estimated demand systems. The nutritional effects of various taxation schemes are compared for households in different age groups and social classes. Focusing on the consumption of saturated fats, fibre and sugar; it is generally found that the impact of price instruments is stronger for lower social classes than in other groups of the population. With regard to age groups, it is mostly the youngest that decrease their demand for saturated fat in response to price changes, while it is mostly the middle-aged who exhibit price responsiveness in their demand for sugar. These groups are however not considered as key target groups for dietary regulation; thus tax instruments may be effective in improving diets on average, but the design of the instruments and the targeting of vulnerable groups with special needs should be done with care. It should be noted that a tax on a single nutrient or food may have undesired effects on the demand for other food components, though this may be avoided by introducing taxes/subsidies on several food products simultaneously.     

Impact of the US–EC price war on major wheat exporters' shares of the Chinese market

China is both the world's largest producer and consumer of wheat. In an attempt to gain a larger slice of the important Chinese market, both the European Community and the United States have offered China subsidised wheat. In addition, other exporters have offered attractive credit arrangements to China. The objective of this paper is to measure the overall impact of these policies on each exporter's share of the Chinese market. To that end, an improved version of the constant market shares model is applied to data on Chinese wheat imports in the 1980's. The results indicate that the United States has been outperforming the other exporters since subsidised US wheat sales were authorised for China in 1987. The implications of the analysis for the smaller exporters and international wheat trade are discussed.     

Determinants of Traditional Sustainability Reporting Versus Integrated Reporting. An Institutionalist Approach

The aim of this study is to analyze similarities and differences between companies with traditional sustainability reporting (TSR) and those that publish integrated reports. Based on institutional theory we identify potential determinants of integrated reporting (IR) and test their relevance empirically in a sample of 309 companies. Our analysis shows that IR companies are different from TSR companies with regard to several country‐level determinants. In particular, investor and employment protection laws, the intensity of market coordination and ownership concentration, the level of economic, environmental and social development, the degree of national corporate responsibility and the value system of the country of origin proved to be relevant. Based on these results, both implications for practice and future studies are derived. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment.     

Non‐Homothetic Multisector Growth Models

Multisector growth (MSG) models are dynamic versions of computable general equilibrium (CGE) models. Non‐homothetic preference (utility) functions are required for the evolution of factor allocations and industrial structures in accordance with consumption expenditure patterns implied by the non‐unitary income elasticities observed in all budget data since Engel in the 1850s. But comparative static general equilibrium solutions and particularly solving the dynamics of MSG models require explicit specifications of all demand and cost (price) functions. On the demand side, the constant differences of elasticity of substitution (CDES) non‐homothetic indirect utility functions and Roy's identity provide the explicit Marshallian demand functions and budget shares. Sectorial constant elasticity of substitution (CES) cost functions and Shephard's lemma provide the explicit relative commodity price functions and the sectorial cost shares and capital–labor ratios. Walrasian equilibria are given by one equation and the multisector dynamics by three differential equations. Benchmark solutions are given for three cost regimes of a 10‐sector MSG model. History patterns of industrial/allocational evolutions are recognized.     

Alienation in corporate America: Fact or fable?

Using NORC annual survey data, the authors selected 21 questions describing respondent attitudes toward job, life in general, and financial status. Respondents were catigorized as management, white collar, blue collar, and those not affiliated with business organizations. Attitudes were compared across the four occupational groups. Little dissatisfaction was found in any but the blue collar group. Management as a group, and men as well as women managers showed high levels of satisfaction, with few significant differences found in responses by men and women. This study does not support the earlier finding of widespread alienation in business firms.Charles B. Sannders is Professor of Business Administration at the University of Connecticut. He has written numerous articles which have been published in various management journals.Hugh M. O'Neill and Oscar W. Jensen are Assistant Professors of Business Administration at the University of Connecticut and the Fairfield University, respectively. Both have written several articles, published in management journals.     

Review Essay

Sen's capability approach has a culturally specific side, with capabilities influenced by social structures and institutions. Although Sen acknowledges this, he expresses his theory in individualistic terms and makes little allowance for culture or social structure. The present paper draws from recent social theory to discuss how the capability approach could be developed to give an explicit treatment of cultural and structural matters. Capabilities depend not only on entitlements but on institutional roles and personal relations: these can be represented openly if capabilities are disaggregated into individual, social and structural capacities. The three layers interact, and a full analysis of capabilities should consider them all. A stratified method implies that raising entitlements will not on its own be enough to enhance capabilities and that cultural and structural changes will be needed.
