Body mass index in families: spousal correlation,endogeneity, and intergenerational transmission

Previous studies have documented spousal and intergenerational correlations in body mass index (BMI) but few have considered familial weight data augmented with socioeconomic and behavioral control variables. This article considers a U.S. dataset that contains such information on husbands, wives, and grown children. Although certain variables (like education, race, and smoking status) are helpful in explaining an individual’s BMI, the BMI of one’s spouse (or parents) remains the most significant predictor of BMI. To help distinguish between correlation and causality in the married-adult BMI regressions, we consider two alternative approaches for dealing with possible endogeneity (due to omitted variables): (1) including spousal variables to proxy for omitted variables and (2) modeling spousal BMI in a hierarchical framework to explicitly allow for a “couple” effect. The results suggest endogeneity of educational attainment, but not smoking status, and support prior research that finds different associations of BMI with income for husbands and wives. For grown children, parental BMI and smoking status are identified as significant predictors.     

Nutrient Prices and Other Socio-Economic and Health Determinants of the Body Mass Index of Canadians

We examine the effect of nutrient prices and other socio-economic and health factors on the Body Mass Index (BMI) of Canadians using the Canadian Community Health Survey (CCHS). The CCHS data does not include information on nutrition intake, and so the price of fat, carbohydrates and protein are included to capture the effects of diet on BMI. The results indicate that changes in nutrient prices in the model have statistically significant impacts on BMI and the direction of the impacts corresponds to hypotheses from the nutrition literature. However, all estimates are inelastic so that the effect of fat taxes or thin subsidies is small. The results also indicate that education is negatively related and income is positively related to BMI.     

网络能力、知识整合与商业模式创新：创业者过度自信的调节作用

网络能力是商业模式创新的重要驱动力。然而，既有研究多聚焦于商业模式创新过程和效果，对其前因探讨不足。基于动态能力理论、社会网络理论与社会认知理论，构建网络能力影响商业模式创新的核心理论框架，探讨知识整合中介效应以及创业者过度自信的调节效应。运用259家创业企业调查数据进行分析，研究发现：内外部网络能力均对商业模式创新具有显著正向影响；知识整合在内外部网络能力与商业模式创新间均起部分中介作用；过度自信在内外部网络能力与知识整合间均起负向调节作用。研究结论可为创业者认知管理和企业商业模式创新路径选择提供理论支撑和实践启示。     

The Value Relevance of Financial and Non-Financial Environmental Reporting

Previous literature on the analysis of the relationship between environmental reporting and financial performance shows mixed results, due to the use of a broad variety of research methods and the lack of objective environmental performance measures. This paper adopts a new approach to explore this relationship, analysing the value relevance of different types of financial and non-financial environmental disclosures. Furthermore, the analysis includes two different types of environmental reporting: compulsory and voluntary. This study examines a sample of listed Spanish companies, using a regression model based on the Ohlson equity-valuation framework. Results suggest a significant market valuation of financial environmental disclosures (investments, costs and contingencies), but not of non-financial. Furthermore, our evidence corroborates the increase of the value relevance of compulsory environmental information.     

Direct and configurational paths of open innovation and organisational agility to business model innovation in SMEs

ABSTRACT

Discussions on opportunities and enablers have remained lacking despite the continued growth of business model innovation (BMI) research. In order to investigate the formation mechanism of BMI in small-medium enterprises (SMEs), we proposed an integrated model, which included factors derived from organisational internal resources and capabilities via the resource-based view (RBV) and dynamic capabilities view (DCV). Structural equation model (SEM) and fuzzy set qualitative comparative analysis (fsQCA) were utilised to test the survey data collected from 245 SMEs in China. SEM results support the hypotheses, except that on the impact of outbound open innovation on market capitalising agility and on BMI. The fsQCA analysis revealed that four configurations of open innovations and organisational agilities can sufficiently explain high levels of BMI, and two configurations of these factors lead to low BMI. The theoretical and practical implications of such findings were also provided.     

经济不确定衡量及对股票市场的影响——基于网络信息检索技术

基于网络信息检索频率的基础上,提出了一种新的衡量经济不确定程度的方法。文章的研究动机来自于经济心理学的研究成果,即经济主体往往会通过信息检索的增加来反映不确定程度的增加。网络信息检索的优点主要体现在检索面广和即时性上,并且与文字相比,网络信息检索更能够客观地反映人们的行为。研究结论显示,以网络信息检索为基础的衡量经济不确定程度的方法与其他若干相关指标相比具有明显的优势,并且这种方法与整个股票市场的收益率和波动率都有着紧密的联系。     

The Cost of Obesity in the United Kingdom

Summary

This study provides economic information on the costs of obesity in the UK using a modified method of attributable risk to establish the full resource implications of treating obesity and associated diseases. Prevalence estimates of obesity, defined as a Body Mass Index (BMI) greater than 30 kg/m², together with estimates of the risk of obesity-related diseases relative to a BMI range close to ideal, are used as the basis of the costing. The total costs of treating obesity and its related diseases are estimated at £355 million (in 1995 prices). The total costs of treating obesity directly, estimated at £3.8 million, are dominated by the costs arising from the treatment of attributable diseases, estimated at £351 million.

Information provision and preferences for education spending: Evidence from representative survey experiments in three countries

Do citizens' preferences about education policies differ across industrialized countries? To gain comparative evidence on public preferences for education spending, we conduct representative experiments with information treatments in Switzerland using identical survey techniques previously used in Germany and the United States. In Switzerland, providing information about actual spending and salary levels reduces support for increased education spending from 54 to 40 percent and for increased teacher salaries from 27 to 19 percent, respectively. The broad patterns of education policy preferences are similar across the three countries when the role of status-quo and information are taken into account.     

How should firms carry out technological diversification to improve their performance? An analysis of patenting of Korean firms

This research aims to analyze how a firm's technological diversification strategies influence its financial performances, in terms of ‘technological diversification’ in broad technology sectors and ‘technological concentration’ on its own core technology, especially in the case of Korean large firms. The data used in the analysis were panel data encompassing the years between 1990 and 2006, which linked Korean firms’ patent information registered in the United States Patent and Trademark Office to the financial data of those firms collected from Korea Investors Service, Inc. (Kis-Value). For the estimation of the panel data, a fixed effect model, which considers the individual firms’ own effect on the financial performance, was used. Tobin's q was used as a dependent variable representing firm performance, while ‘broad technology diversity’ and ‘core technology diversity’ were used as the focal explanatory variables. The results show that a firm seeking to have more technological assets should invest in a broad technological diversification strategy in its search for new business opportunities; it should likewise concentrate on the core technology in order to maintain its financial performance.
