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.     

Price transmission,asymmetric adjustment and threshold effects in the cotton supply chain: a case study for Vidarbha,India

This study examines price transmission asymmetries in Vidarbha's (India) cotton supply chain from 2002 to 2012. The analysis takes account of thresholds in price adjustments toward their long‐run equilibrium. The first stage considers the price dynamics between international and Indian domestic cotton prices. The second stage considers price transmission from domestic to farm gate cotton prices in Vidarbha. Results from the first stage indicate that Indian and international cotton markets are well‐integrated. In contrast, the second stage reveals significant threshold‐type nonlinearities as well as asymmetries in price transmission between domestic and farm gate prices. The short‐run dynamics suggest that the pass‐through from domestic to farm gate prices is larger when domestic prices decrease than when they increase. Moreover, back of the envelope calculations suggest that the loss in revenue for a typical farmer from a decrease in domestic price is larger than the gains from an increase in domestic price of the same magnitude. The implication is that traders benefit from price fluctuations at the expense of farmers. Evidence from fieldwork in Vidarbha suggest that asymmetries revealed in this analysis may be linked to trader's market power and inadequate market information among farmers.     

<Emphasis Type="Italic">Sylvania’s</Emphasis> Indian Precursor and Its Legacy

The starting point of this paper is a January 1977 judgment of the Indian Supreme Court, which applied the rule of reason to vertical restraints and anticipated many of the arguments of the Sylvania judgment. After summarizing the background of the Indian case, I set out the main points of similarity and difference between the two judgments, and finally assess the somewhat erratic influence of post-Sylvania antitrust thinking on Indian competition law and jurisprudence.     

Demand Curves for Stocks Do Slope Down: New Evidence from an Index Weights Adjustment

Weights in the Toronto Stock Exchange 300 index are determined by the market values of the included stocks' public floats. In November 1996, the exchange implemented a previously announced revision of its definition of the public float. This revision, which increased the floats and the index weights of 31 stocks, conveyed no information and had no effect on the legal duties of shareholders. Affected stocks experienced statistically significant excess returns of 2.3 percent during the event week, and no price reversal occurred as trading volume returned to normal levels. These findings support downward sloping demand curves for stocks.     

Supply network capacity planning for semiconductor manufacturing with uncertain demand and correlation in demand considerations

A semiconductor supply network involves many expensive steps, which have to be executed to serve global markets. The complexity of global capacity planning combined with the large capital expenditures to increase factory capacity makes it important to incorporate optimization methodologies for cost reduction and long-term planning. The typical view of a semiconductor supply network consists of layers for wafer fab, sort, assembly, test and demand centers. We present a two-stage stochastic integer-programming formulation to model a semiconductor supply network. The model makes strategic capacity decisions, (i.e., build factories or outsource) while accounting for the uncertainties in demand for multiple products. We use the model not only to analyze how variability in demand affects the make/buy decisions but also to investigate how the correlation between demands of different products affects these strategic decisions. Finally, we demonstrate the value of incorporating demand uncertainty into a decision-making scheme.     

Customer Satisfaction with E-Retailers: The Role of Product Type in the Relative Importance of Attributes

It is of strategic importance for e-retailers to allocate their resources to various service attributes according to their relative importance. How does one determine the relative importance of different service attributes? Does the relative importance of different service attributes remain the same across different product categories? These questions must be addressed by researchers and e-retailers. Since customer ratings for service attributes are highly correlated, modeling methods other than traditional regression models should be used to analyze the relative importance of service attributes to overall customer satisfaction. As such, this article utilizes neural networks in order to study the relative importance of e-retailer service attributes. Importantly, this article shows that the relative importance of e-retailer service attributes varies across different product categories (i.e., convenience, shopping, and specialty goods).

Military coups and the consequences of durable de facto power: the case of Pakistan

We analyze the role of the military as an independent interest group within the State, based on the two-player theoretical framework of Acemoglu and Robinson (Economic origins of dictatorship and democracy. Cambridge University Press, Cambridge 2006); we innovate by introducing the military as a third player, a specialist in violence. In particular, we study the conditions under which a democratic regime can prevent a transition to an authoritarian regime via a military coup, when a coup requires the support of both the military and the elite sections of the civilian population. We carry out an historical case study of Pakistan to motivate and illustrate our argument, and show that Pakistan’s three coups since independence are associated with parameter shifts in our model.     

Quantitative restrictions and Indian imports

Many governments in LDCs tend 3o rely heavily on import control for achieving adjustments in the balance of payments. The empirical analysis of imports of these countries has failed to address the issue of quantitative restrictions satisfactorily. In this paper, a set of disaggregated import demand equations are specified which attempt to capture the government's decision regarding quota restrictions. The model postulates that the overall level of imports is determined by expected foreign exchange availability while the composition of imports (once the level has been decided) is based on political and economic priorities and on relative prices.
