A theory of gender differences in parental altruism

Abstract.  We offer a theory of gender differences in parental altruism based on the asymmetry that female fertility is constrained but male fertility is relatively unconstrained. Modelling human preferences as having been shaped during the Pleistocene, we derive evolutionarily stable, co‐evolved male and female preferences for altruism towards one's children. We demonstrate that there would be gender differences in parental altruism that depend on the relative abundance or scarcity of resources and the importance and substitutability of parental inputs in promoting the survival of offspring. The results point to greater altruism in females, under plausible conditions. JEL Classification: D64, J16, P46     

From Planning Models to Descriptive General Equilibrium

I had known Manohar Rao for a long time. For many years I tried to lure him to join the Indira Gandhi Institute of Development Research. He always gave me his disarming smile but his loyalty to Bombay University and to his students was unshakable. He was deeply interested in improving tools for better policy analysis. Hence in this paper I raise some related issues.

     

“Do Fiscal Deficits Influence Current Accounts? A Case Study of India”

This paper examines the effects of fiscal deficits on the current account deficits in the Indian economy. In many developing countries, fiscal deficits are mostly financed through monetization, causing crowding out of private investment expenditures. However, fiscal deficits in India are mostly financed through official borrowings from various external sources, leading to higher interest payments and outgoings on the external account. Such a policy could eventually precipitate balance of payments crises despite favorable trade account and real exchange rate. Data over three decades for the Indian economy show that, in addition to the real exchange rate and the ratio of private investment to GDP, fiscal deficits significantly contribute to the current account deficits.     

Quality-enhancing trade liberalization

This paper examines the effect of trade liberalization on the quality of industrial goods produced by a developing country. The intermediate goods used as inputs to industrial production are assumed to be non-traded and produced by firms with market power. It is shown here that for a certain range of human capital levels, exposure to free trade, instead of resulting in de-industrialization, can raise welfare through an improvement in the quality of domestically produced industrial goods.     

区域电力市场的十大障碍及其对策

中国迄今已经在电力改革方面取得了很大进展.目前所处的行业重组阶段,旨在为建立竞争性电力市场奠定必要的基础.尽管最初的省级电力市场试点为提高行业的经济和技术水平创造了条件,但建立区域电力市场以优化资源配置和提高效率的潜力显然更大.但是,建立区域电力市场的难度远大于建立省级电力市场.本文讨论在中国建立区域电力市场的障碍因素及其可以采取的应对措施.     

Valuing Mortgage Insurance Contracts in Emerging Market Economies

We develop a new option-based method for the valuation of mortgage insurance contracts in closed form in an economy where agents are risk neutral. While the proposed valuation method is general and can be used in any market, it may be particularly useful in emerging market economies where other existing methods may be either inappropriate or are too difficult to implement because of the lack of relevant data. As an application, we price a typical Serbian government-backed mortgage insurance contract.     

Market orientation and customer satisfaction: Evidence from British machine tool industry

This paper examines empirically the relationship between market orientation and business performance in the context of British machine tool industry. An industry-specific market orientation scale was developed. Factor analysis revealed that there were four latent dimensions underlying the market orientation: customer orientation, competitor orientation, departmental responsiveness, and customer satisfaction orientation. Findings suggest that customer orientation and customer satisfaction orientation have a stronger impact on performance than the other dimensions, and that competitor orientation has a U-shape relationship with performance. Departmental responsiveness did not appear to be significantly related to the business performance. Managers could use the multidimensional conceptualization to develop particular kinds of orientations required for better performance.     

Heterogeneity in Food Demand among Rural Indian Households: The Role of Demographics

Food expenditures, influenced by social, demographic, and economic factors, constitute a significant proportion of the typical rural Indian's household income. Based on cross‐sectional household data, this study employs the Quadratic Almost Ideal Demand System to estimate food demand among rural Indian households. Special attention is given to the rural household's two‐stage budgeting in total food expenditure and then to a demand for a specific food item. Conditional and unconditional expenditure and price elasticities for seven food groups are estimated. Results indicate that own‐price elasticities for each group are negative ranging from fairly inelastic to elastic range. Expenditure elasticities indicate that food items are a normal necessity to luxury goods. Additionally, socio‐demographic factors play a significant role in food consumption patterns. Based on our unconditional expenditure elasticities, we also project food demand from rural Indian households for next two decades. Les dépenses alimentaires, qui sont influencées par des facteurs socioéconomiques et démographiques, absorbent une partie considérable du revenu des ménages ruraux typiques en Inde. Dans la présente étude, nous avons utilisé le modèle de demande quasi idéal quadratique pour estimer, à l'aide de données transversales sur les ménages, la demande alimentaire des ménages ruraux en Inde. Nous avons accordé une attention spéciale à la budgétisation en deux étapes des dépenses alimentaires totales et à la demande d'un produit alimentaire particulier du ménage rural. Nous avons estimé les dépenses conditionnelles et inconditionnelles et l’élasticité‐prix de sept groupes alimentaires. Les résultats de notre étude indiquent que l’élasticité‐prix de chaque groupe est négative et qu'elle varie de plutôt inélastique à divers degrés d’élasticité. L’élasticité des dépenses indique que les produits alimentaires varient de nécessités de base à produits de luxe. Les facteurs sociodémographiques jouent également un rôle important dans les habitudes de consommation alimentaire. D'après les élasticités des dépenses établies dans notre étude, nous avons estimé la demande alimentaire des ménages ruraux en Inde pour les deux prochaines décennies.     

Off‐Farm Work,Intensity of Government Payments,and Farm Exits: Evidence from a National Survey in the United States

The last three decades have witnessed the continued exit of households from primary agriculture in the United States, where the average annual gross exit rate has averaged 10% per year. Understanding exit behavior is one key to future farm structure, management of abandoned land, depopulation of rural areas, and agricultural policy, including government program payments. This study empirically estimates the determinants of exit decisions of farm households. Particular attention is given to the roles of intensity of government payments and off‐farm work decisions of farm couples in the exit decision. Using a large farm‐level survey and controlling for endogeneity, results indicate that farm households with reduced intensity of government payments are more likely to exit farming. Households where the operator spouse works off the farm are more likely to exit farming. Additionally, households with older farmers, with the farm operator and spouse raised on a farm, and households operating farms located in Northern Great Plains are more likely to exit farming.     

Preparing for higher inflation: Portfolio solutions using U.S. equities

Investors have always been interested in reducing inflation risk in their portfolios. However, investors face different types of inflation than those measured by the Consumer Price Index (CPI). Moreover, different asset classes can be used to hedge portfolio inflation. In this paper, we show how individual equities can be used to construct equity portfolios sensitive to customized inflation targets. We illustrate portfolios for three types of inflation: US headline CPI, Forbes Cost of Living Extremely Well Index, and the US Medical Care Price Index. We also show how alternative weighting schemes, such as minimum volatility and maximum inflation beta, can be used to construct inflation‐hedged portfolios.
