Does the relationship between income and child health differ across income groups? Evidence from India

This study explores the relationship between child health and socioeconomic status (health-income gradient) using the Indian Human Development Survey-II (2011-12) for children up to 5 years of age. Unlike previous studies our empirical analysis allows the gradient to vary across different income intervals using linear and cubic spline regressions. We use objective measure of child health - height-for-age Z-scores and find that an increase in income, on an average leads to reduction in prevalence of stunting. We also find differential effect of income on health across the income distribution with no effect of income on child health for very poor households. Further we explore underlying factors explaining the gradient and find that maternal health, housing quality, sanitation, non-infectious environment, media exposure to women and a safe neighbourhood are transmission channels that affect child health and together they explain almost 40% of the overall income effect. One of the major implication of our findings is that any policy to increase income of poor households should be complemented with a health policy designed specifically towards children as poor households are less likely to allocate additional income to child health.

An additional approach for interpretation of multiple discriminant analysis in business research

Several useful approaches for interpreting multiple discriminant analysis (MDA), including graph plots, have recently been illustrated for business researchers. This article proposes and illustrates an extension of the traditional plotting procedures in MDA that allows the depiction of both group overlaps and differences among groups. We also discuss several other interpretational approaches in MDA.     

Bank holding company affiliation and contracyclical lending by mortgage bankers

Bank holding companies have made significant inroads into the mortgage banking industry, primarily by acquisition. Federal Reserve Board approval of acquisitions is contingent upon the expectation of net public benefits. This study analyzes one of the benefits that BHCs claim will arise from acquisition of mortgage bankers—the flow of funds into housing will become more cyclically stable. Test results on a 33-firm sample of independent and BHC-affiliated mortgage bankers for 1973–1975 provide little support for this claimed public benefit.     

A quantitative model for the evaluation of technological alternatives

This paper presents a quantitative model that may be of use to the national development planners, investment funding authorities, and entrepreneurs, who are confronted with the problems of choosing the appropriate technology among many available alternatives. The model provides a systematic and analyst-independent methodology for the multicriterion technology selection process, which requires consideration of socioeconomic as well as technological factors. The procedure is mathematically straightforward and has the capability of integrating both objective and subjective aspects of the evaluation process, resulting in a unified technology measure as a guide for decision making. A case study is presented to illustrate the applicability and workability of the development model.     

信任、专业化分工与家族企业治理机制选择

信任和专业化分工是影响我国家族企业治理机制选择的主要变量.本文通过动态地阐释我国家族企业的信任结构、家族主义信任的拓展及信任、专业化分工程度对家族企业治理机制选择的影响,提出了一个基于信任与专业化分工双维度的家族企业治理机制选择的综合性描述框架,即家族企业主在权衡受信任程度影响的交易成本和受专业化分工程度影响的企业效率的基础上,相机地选择古典式治理、泛家族式治理、网络式治理和现代式治理机制.     

产业特性、区域异质性与我国国内价值链分工

基于区域间投入产出表和上游度模型,构建国内价值链分工地位、嵌入位置和增值能力指数,系统刻画1997-2007年我国国内价值链分工形态,应用面板数据模型对国内价值链的产业和区域异质性进行实证研究。结果发现,我国总体尚未形成严格的东中西梯次分布的价值链空间格局,产业属性决定国内价值链嵌入位置和分工地位,产业国有比重越高越有助于价值链分工地位提升,产业资本劳动比提升嵌入位置却恶化分工地位,产业规模对分工地位没有显著影响;区域FDI导致价值链低端锁定和增值能力弱化,区域创新投入强化产业直接价值增值、市场化水平的提高显著提升价值链嵌入位置,但二者与价值链分工地位的关系均不显著。优化市场环境、降低制度成本、选择差异化的区域产业升级路径是构建国内价值链的关键。     

效率与平衡视角下京津冀城市群产业发展水平测度

基于效率和平衡视角,通过纳入结构差异和体量差距构建新的产业发展水平测度方法,以此对京津冀城市群产业发展效率与平衡水平进行评价。测度结果显示：京津冀城市群各城市效率水平差异较大,中心城市北京的效率水平过高导致产业过度聚集。在较长时间内,城市群产业发展平衡水平并无太大变化,但是城市群内城市的竞争压力逐渐向城市群西南方向转移。进一步讨论结果显示：新方法的测度结果是可信的;金融、公共服务等行业在城市群内的分布出现了一定程度的优化,但是制造、教育和文娱等行业却在不断恶化,总体来看,京津冀城市群产业结构有待进一步优化。
