Income and price elasticities of demand at low levels of real income

For levels of real per capita income starting at 3% of the U.S. per capita income in 1975, income and price elasticities of demand are tabulated. The prominent role of food consumption for low-income households is emphasized.     

A cointegration analysis of seafood import demand in Caribbean countries

This article re-examines the relationship between growth in per capita income and environmental degradation using econometric techniques appropriate for smooth transition regressions with panel data. This is a more intuitive and flexible methodology than the polynomial models widely used in the literature, and it can reconcile some of the mixed results found previously. The methodology is applied to carbon dioxide emissions from nonOECD countries over the period 1971 to 1997. Although there is no evidence of environmental Kuznets curve, we find two regimes, namely a low-income regime where emissions accelerate with economic growth and a middle to high-income regime associated with a deceleration in environmental degradation.     

The measurement of income and price elasticities

In a complete system of disaggregated demand equations, the econometrician must limit himself to the measurement of a small number of parameters for each commodity. Since interest often focuses on the income and own-price elasticities for each good, it is natural to look for models which allow independent measurement of these while providing plausible assumptions about the less essential responses. This paper surveys a number of common theoretical specifications which purport to do this, and argues that these are unsatisfactory. The conclusions are supported by an empirical comparison on British data of the results of three models, one of which is new and is designed to remedy some of the deficiencies of standard practice.     

Long-run income and price elasticities of demand for Colombian nontraditional exports: a multivariate cointegration framework

A long run income and price elasticities of demand is estimated for Colombian nontraditional exports through a multivariate cointegration analysis. Based on the combination of cointegration and exogeneity concepts and the inclusion of the complete dynamic system, the paper shows the existence of a long-run relationship among nontraditional exports, relative price and foreign demand, and higher long-run elasticities than those provided by the long-run cointegration vector coefficients that are usually reported in the trade literature.     

LIML estimation of import demand and export supply elasticities

I apply limited-information maximum likelihood (LIML) to estimate import demand and export supply elasticities for a range of eurozone countries. The results highlight inconsistencies in the parameters estimated by LIML relative to an estimator that is robust to heteroskedasticity. The nature of the structural equations reveals complications generated by the limiting behavior of the parameters that can be replicated in finite samples. The results of simulations underscore improvements in parameter estimates in a three-dimensional panel, suggesting that the problem of limiting behaviour can be overcome in larger dataset/panels.     

A cross-country tabulation of income elasticities of demand

International cross-sectional Engel curve estimates are used to compute income elasticities of demand for eight commodity groups and 15 countries.     

Simultaneous estimation of income and price elasticities of export demand,scale economies and total factor productivity growth for Brazil

This article focuses on a growth model in which (unlike other models) low (high) export demand elasticities and the fact that developing countries are importers of capital goods help explaining the slow (high) growth of these countries in the transition and in the steady state. The question arises whether export demand elasticities are low or high. For answering this question, export demand elasticities for the case of Brazil are obtained by estimation of the model. As a by-product of estimating the model, we obtain estimates for total-factor productivity growth and for scale economies. Based on the results from estimation we calculate steady-state growth rates, engine and handmaiden effects of growth as well as dynamic steady-state gains from trade. The model and the results are discussed in regard to several strands of literature.     

Export demand elasticities and productivity as determinants of growth: estimates for Mauritius

In this article, we combine the export led and import led growth hypotheses in a growth model in which the importation of foreign capital goods and the demand elasticities of own export products explain the growth opportunities and the technical progress of developing countries. This model, based on imported capital goods, uses Mauritius’ data on capital investment, employment, export partners’ growth and terms of trade to estimate price and income elasticities of export demand, total factor productivity growth and economies of scale. These elasticities are then used to assess how the growth in export partners’ income is converted into domestic growth. The implications of the presence of low or high export demand elasticities are discussed by relating them to various strands of trade and growth literature. Based on the results of this estimation, we also calculate steady state growth rates, engine and handmaiden effects of growth as well as the dynamic steady state gains from trade for this latecomer export economy. The implications of steady state results are also discussed in the light of the Mauritian employment and growth perspectives.     

Domestic price distortions and agricultural income in developing countries

The static effects on agricultural crop production and income arising from the correction of three common policy biases in developing countries - the underpricing of food, agricultural export taxation, and currency overvaluation - are examined analytically and empirically (using Philippine data) based on a model of the agricultural sector with the food-export crop tradeoff in production as a key component. The findings argue for a careful examination of the relative efficiencies of different liberalization policy instruments in advancing specific development objectives in cases where, possibly for socio-political reasons, not all price distortions in interrelated markets can be corrected.     

Pooling surveys in the estimation of income and price elasticities: An application to Tunisian households

This paper presents a methodological extension of Deaton's (1990) model for estimating price elasticities, by pooling Tunisian data from several surveys to improve the inter-cluster variability of unit values which is one of the key elements used in the derivation of these elasticities. Since the surveys cover a relatively long period, possible structural changes in consumption behaviour occurring over time are accounted for by postulating that certain response coefficients of the basic model vary from one survey to the other. The own price and cross price elasticities calculated using appropriate estimates of the extended model are satisfactory both from the economic point of view of their sign and the statistical point of view of their significance and superior to those obtained using a single survey.

The competitive nature of the nursing home industry: price mark ups and demand elasticities

Nursing home markets are likely to deviate from a competitive structure because of limitations on entry imposed by Certificate of Need (CON) regulations and the potential for product differentiation along such attributes as location, religious affiliation and quality. This paper investigates the structure of nursing home markets in New York State by calculating price mark ups and residual private pay demand elasticities. It shows that the residual demand elasticity is bound by estimates based on price mark ups above marginal costs and above Medicaid rates. This approach allows estimation of demand elasticities in all markets, whether or not CON regulations constrain bed supply. Mean price elasticities (in absolute value) calculated for nursing homes in New York State in 1991 ranged from 3.46 to 3.85.     

Expenditure elasticities of the demand for leisure services

Although some research has already focused on the analysis of expenditure elasticities of leisure demand, some shortcomings with regard to the content and the underlying theoretical model as well as the applied methods exist. This article aims at avoiding these problems to provide consistent derivatives of leisure service expenditure elasticities. Therefore, a regular demand system is derived from microeconomic duality theory. To implement leisure specific demand factors (i.e. demand- and supply-based sports and recreational opportunities as well as sports and recreational preferences) while still being consistent with neoclassical demand theory, the basic model is extended by applying the demographic translation framework. Data of the continuous household budget survey (n?=?7724) from Germany is used for the estimation of the derived demand system. It is shown how sensitive the results are depending on the applied (censored) regression model: 16 out of 18 analysed services are indicated as luxury goods based on the findings of the Tobit model type I but as necessities based on the findings of the Tobit model type II. Possible implications are presented and discussed.     

Aggregation effects on price and expenditure elasticities in a quadratic almost ideal demand system

Abstract.  While it is well known that demand elasticities calculated at the macro level will in general differ from those calculated at the micro level because of aggregation effects, there remain the questions of how large the effects are and how they vary with the degree of inequality in the income distribution. We explore these questions with models based on a quadratic version of the Almost Ideal Demand System. We investigate the elasticity differences theoretically and then calibrate the models and generate numerical results, using income data for seven countries with widely different distributions. The aggregation effects are found generally to be rather small, even with highly unequal income distributions.     

The measurement of income and price dispersion in cross-country demand analysis

Measures are formulated for the dispersion of real income and relative prices across countries. They are applied to 30 countries in 1975 for 10 groups of consumer goods.     

On the effect of income and relative price on demand for health care: EC evidence

This paper demonstrates that the relative price of health care could be used to explain the conflicting results of the empirical studies which attempt to measure the income elasticity of demand. Our empirical results, based on a conventional model and cross-national data set for the EC, show that whereas health care may be labelled as a luxury good, the large income effect can be interpreted as merely offsetting the price effect.     

Arithmetic visibility estimates for OECD countries with three government levels

The importance of fiscal visibility has been well known for a long time but attempts to quantify it by taking the internal structure of every type of revenue and expenditure in a fiscal system into consideration are recent. Indicators used until now rest on structural parameters combined in a multiplicative way with a 0 estimate always resulting in at least one of such factors being null. An alternative way to measure fiscal visibility consists of combining parametric values in an additive instead of a multiplicative form. Calculations can then show estimates which are much more sensitive to the initial values. The aim of this contribution is to present new additive indicators that are applied to several territorial government levels in Australia, Austria, Canada, Germany, Spain, Switzerland, and the U. S. Comparisons, conclusions, and comments are offered for general development. An earlier version of this article was presented at the 55th International Atlantic Economic Conference, Vienna, Austria, March 12–16, 2003. The author is indebted to participants of this conference for helpful comments. The responsibility for any errors or shortcomings are the author's.     

Some international evidence on the stability of aggregate import demand function

This paper empirically analyses the stability of the aggregate import demand function for G7 countries. The standard cointegration test and a test developed by Gregory and Hansen are performed. The results of standard cointegration tests suggest that there is no stable cointegrating relation between real import, real GDP and relative import price for all G7 countries. The cointegrating relation is empirically supported for France and Germany if structural change for cointegrating vector is explicitly taken into consideration. The cointegrating relation is empirically rejected for Canada, Italy, Japan, the UK and the USA. Thus, the stimulation of domestic business conditions will not necessarily link the quantity of imports for these five countries.     

Charitable contributions and tax price elasticities for nonitemizing taxpayers

This paper uses a balanced panel of taxpayers to examine the price and income elasticities for charitable contributions for nonitemizing taxpayers. One-way and two-way static fixed effects models are used to estimate these elasticities. Additionally, this paper incorporates dynamic panel analysis within the constraints of the data. The data are from the Individual Tax Model File panel of taxpayers, maintained by the University of Michigan. This paper finds no significant price elasticities for nonitemizers. The results of this paper would argue that there is no compelling economic reason to extend charitable contribution deductions to nonitemizers.     

Long-run estimates of interfuel and interfactor elasticities

Meta-analyses of interfuel and capital-energy elasticities of substitution show that elasticity estimates are dependent on the type of data − time series, panel, or cross-section − and the estimators used. Econometric theory suggests that the between estimator might generate the best estimates of long-run elasticities but no existing estimates of elasticities of substitution have used it. Alternatively, Chirinko et al. argued in favor of estimating long-run elasticities of substitution using a long-run difference estimator. We provide estimates of China’s interfuel and interfactor elasticities of substitution using the between and long-run difference estimators. To address potential omitted variables bias, we add province level inefficiency and national technological change terms to our regression model. The results show that demand for coal and electricity in China is very inelastic, while demand for diesel and gasoline is elastic. With the exception of gasoline and diesel, there are limited substitution possibilities among the fuels. Substitution possibilities are greater between energy and labor than between energy and capital. The results are quite different to some previous studies for China but coincide well with the patterns found in meta-analyses for long-run estimates of elasticities of substitution.
