ESTIMATING SPATIAL CONSUMER PRICE INDICES THROUGH ENGEL CURVE ANALYSIS

In this paper we propose a method of estimating spatial multilateral price index numbers from cross‐section consumer expenditure data on different items using Engel curve analysis. The novelty of the procedure is that it overcomes the problem of data inadequacy, a problem that is shared by most of the developing countries. The procedure does not require item‐specific price/unit value data and price index numbers can be calculated from consumer expenditure data grouped by per capita income/total consumer expenditure class in a situation where unit level data are not available. To illustrate the method, we use published state‐specific data of the 50th round (1993–94) and 55th round (1999–2000) consumer expenditure surveys of India's National Sample Survey Organization (NSSO) and calculate the spatial consumer price index numbers for 15 major states of India, with All‐India taken as base, separately for the rural and the urban sector for each round.     

DEMAND THRESHOLD,ZERO EXPENDITURE AND HIERARCHICAL MODEL OF CONSUMER DEMAND

Consumer expenditure surveys often show households reporting zero consumption of some commodities. Three reasons for this are recognized in the literature: (i) infrequency of purchase, (ii) a strong brand preference for differentiated products and (iii) misreporting. However, sometimes the number of households reporting zero consumption is seen to decline with income. To capture this phenomenon, which does not fall into any of the categories mentioned above, we propose a hierarchical preference structure and identify a class of recursive utility functions representing this structure. An empirical illustration based on Indian consumer expenditure data is provided.     

India's Global Trade Potential: The Gravity Model Approach

Abstract

In this article an augmented gravity model equation has been used to analyze the world trade flows using a sample of 146 countries. The coefficients thus obtained are then used to predict trade potential for India. Ordinary Least Squares with cross-section data for the year 2000 have been used for estimation. The results show that all three traditional “gravity” effects are intuitively reasonable, with statistically significant t-statistic often exceeding 50 in absolute value. Alternative measures of gross national product (GNP) dollar value and purchasing power parity do not alter either the sign or significance of different explanatory variables. Historical and cultural similarities also impact positively upon bilateral trade. As concerns India's trade potential, the model shows that there is tremendous potential with China and trade can more than double if barriers and constraints are removed. Our estimates also indicate a huge potential, of the order of US$6.5 billion, with Pakistan.

Estimating Purchasing Power Parities from Household Expenditure Data Using Complete Demand Systems with Application to Living Standards Comparison: India and Vietnam

This study departs from the previous literature on purchasing power parity (PPP) by proposing a demand system based methodology for calculating the PPP that takes account of consumer preferences and allows for the substitution effect of price changes. The methodology is used to calculate the PPP between the Indian Rupee and the Vietnamese Dong. The study allows for regional variation in preferences and price changes both inside the country and between countries. It proposes and applies a methodology for constructing prices from unit values after adjusting them for quality and demographic effects. The adjusted unit values are used as prices in the demand estimations, and the demand parameter estimates are used to calculate both spatial prices within each country and the PPP between the two countries within a consistent framework. The study illustrates the usefulness of preference consistent methods to calculate the PPP by applying the PPPs to compare living standards between India and Vietnam. The significance of the results follows from the fact that the levels of living comparisons are quite sensitive to the PPP used in converting the Rupee expenditure into Vietnamese Dong. The present results on food PPPs question the relevance of the PPPs from the ICP project in cross‐country welfare comparisons especially in a period of high food inflation.     

Gender Bias in Education in West Bengal

This paper attempts to capture gender bias at two different levels of education, namely, below class-10 and above class-10 using NSSO 64th round education expenditure data on West Bengal. The analysis for the below class-10 level involves an intra household framework and Heckman’s two step model. Further, for this section the analysis is split up into classes 1–8 and classes 9–10 in view of the Right to Education act (2005). For above class-10 level, gender bias has been captured through a multinomial logit model for selection of subjects across households.

     

Inter-firm scalar linkage in India: A class within the small scale industry

Along with the growing industrial sector, functional complementarity between large and small scale enterprises has become a widely prevalent phenomenon. Expanding the base of the industrial production leads to division of processes where large and small scale units operate as complementary to each other. Such complementarity and division of labour between the different sized units results into cost minimization, and acceleration in growth of the manufacturing sector.However the extent and the pattern of functional complementarity (between large and small scale enterprises) is likely to be conditioned by market as well as institutional factors. Therefore, in order to examine the impact of interscale complementarity in terms of growth as well as of distribution of gains across large and small scale enterprises it is very important to learn about the nature of interfirm linkages and the process through which linkages get established. It is in this context, the present paper furnishes details based on a case study of Textile Machinery Parts Manufacturing (TMP) industry in a metropolitan city (Ahmedabad). The industry represented is constituted by a large number of small scale firms that are engaged in fabricating replacement parts for the users of machinery equipments (i.e. Textile Mills) who operate on a large scale. Owing to wide range of products, and in case of some parts higher frequency of replacement, the TMP industry, at least till recently, has sustained a large number of small firms.The major findings of the analysis are: (i) The incidence of inter-firm linkages is limited to about a third of the small scale firms; (ii) Among various forms of linkages the marketing linkages are the most predominant (iii) The linkage relationship has been a positive factor in determining the performance of the small scale firms; (iv) Personal contacts play an important role in inter-firm linkages, thus benefits of linkage relationship are mainly confined to a small social-group of industrialists; (v) While the small scale suppliers operate under a highly competitive market, the buyers often enjoy oligopsonist's advantage; hence the gains of competitive efficiency tend to favour the large scale sector.     

Asset pricing for inefficient markets: Evidence from China and India

Over last four decades, evidence of market inefficiencies has been widely documented by several scholars for all major stock markets in the globe. Chinese and Indian markets are not exempt. Inefficiencies in these markets are described by many authors as roots of all mispricing. Mispricing might be the outcome of application of familiar asset pricing models which may mislead an investor into adopting inappropriate policies for his new investments or for reallocating his old investments. In an alternative approach, we propose a transformation on original market returns in the objective of relaxing the strong assumption of market efficiency behind application of an asset pricing model. This modification will widen the scope of rational models on asset pricing ranging from an efficient to an inefficient market.     

Measuring income responses: A log-quadratic demand model for consumers in India

This paper attempts to capture the non-linearity of income responses of fairly disaggregated item groups with the help of a quadratic system of demand equations, introduced herein. Empirical performances of the quadratic system and some other models have been examined using Indian consumer expenditure data.The author wishes to thank Professor Dipankor Coondoo and the referees for thei helpful comments.
