On the relationship between GDP and health care expenditure: A new look

In this paper we analyze the relationship between income and health expenditure in 31 Organization for Economic Cooperation and Development (OECD) countries. We focus on the differences between short and long term elasticities and we also check the adjustment process of health care expenditure to changes in per capita Gross Domestic Product (GDP) and its cyclical and trend components. In both cases, we test if results differ in countries with a higher share of private expenditure on total health expenditure. Econometric results show that the long-run income elasticity is close to unity, that health expenditure is more sensitive to per capita income cyclical movements than to trend movements, and that the adjustment to income changes in those countries with a higher share of private health expenditure over total expenditure is faster.     

Manufacturing consumption,relative prices,and productivity

I study the patterns of manufacturing consumption expenditures across a broad set of countries that differ in their level of development using disaggregated expenditure and price data. The relative price of manufacturing tends to decline with income and the real share rises with income, particularly for countries in the top half of the income distribution. I find that the nominal expenditure share of manufacturing displays a hump-shape pattern with respect to the level of income per capita. I document that the income elasticities of the relative price of individual manufacturing categories lie in a wide range. However, since most categories have a negative elasticity, the average elasticity for manufacturing is negative. In addition, most aggregations of individual categories, regardless of the criteria used, yield manufacturing sub-sectors that feature a negative income elasticity of its relative price and the variation across income in nominal expenditure shares tends to mask a larger variation across income in real shares. Using a standard development accounting framework, I report large differences in productivity across countries for manufacturing categories. I also find some differences in productivity across countries for manufacturing sub-sectors, but these differences are smaller than the differences between manufacturing and services and considerably smaller than the differences across individual manufacturing categories.     

The determinants of health care expenditure in Australia

The objective of this article is to examine the long-run relationship and short-run dynamics of the health care expenditure in Australia during the period 1960–2003. Consistent with the conventional findings, the income elasticity for health care is found to be greater than one, suggesting that health care is a luxury good in Australia. Demographic structure is found to exert a significant positive impact on health care expenditure. An increase in the accessibility to health care services is associated with higher per capita real health care expenditure. Finally, public funding of health care appears to have a contributory effect on the formation of health care expenditure in Australia.     

Aggregate health care expenditure in the United States: evidence from cointegration tests

Unlike recent studies that are based on international cross-sectional series, this paper attempts to quantify the role of the determinants of aggregate health care expenditure per capita, using time-series data for the period of 1960–87 for the United States. The paper applies the relatively new procedures of unit root testing, cointegration and error-correction modelling. The evidence supports cointegration. Although, the results indicate that per capita income, age of the population, number of practising physicians, and public financing of health care are important determinants, the age structure of the population and number of practising physicians emerge as the major determinants of aggregate health care expenditure in the United States.     

Health spending and public pension: evidence from panel data

This article empirically investigates the determinants of aggregate health expenditure in a panel of OECD countries from 1980 to 2005. We differ from most existing studies by testing some new determinants motivated by recent theoretical advances in the literature. We find that a one percentage increase in public pension payments per elderly person leads to approximately a one third percentage increase in aggregate health spending, and this effect is significant and robust across a variety of model specifications. A back of the envelope calculation based on this estimate suggests that the expansion of the public pension programme on average accounts for approximately over one fifth of the rise in aggregate health expenditure as a share of GDP in the set of OECD countries during 1980–2005. In addition, we find that the estimated effect of GDP per capita in our model ranges from 0.66 to 0.80, which is consistent with the results from some recent studies, and thus further reinforces the finding in the literature that health care is not a luxury good.     

NEW INSIGHTS INTO THE STRUCTURE OF THE WORLD ECONOMY*

The United Nations' newly completed study of purchasing power parities covering 34 countries varied in region, income level, and form of economic organization shows the systematic differences between the usual view of the structure of the world economy arising out of international comparisons based upon foreign exchange rate conversions and the structure one sees when actual prices are available. The real per capita GDP of developing countries is understated relative to developed countries when exchange rates are used in converting countries' national income accounts to a common currency, with the degree of understatement for any two countries being inversely related to the per capita income difference between them. The reason for this is that relative prices in the non-traded goods sector are lower relative to traded goods prices in low income countries. The systematic pattern observed in the 1975 data of the 34 countries has been extrapolated over time and space to get estimates of GDP for other years and countries. In the absence of detailed price data, the real shares of final expenditures devoted to particular components of the total can only be estimated as the proportion of own currency total expenditure devoted to the components. The observed differences in the pattern of prices of poor countries relative to rich for different components makes this clearly wrong for international comparisons, and in systematic ways. For example, (i) the relative price of services compared with commodities in poor countries is lower than in rich; so the apparent tendency of the share of services to rise as a country's income rises disappears when real quantities are considered; similarly, (ii) the relative price of capital goods is greater in poor countries compared with rich ones, so the difference in investment ratios out of GDP between rich and poor countries is understated.     

Does environmental quality influence health expenditures? Empirical evidence from a panel of selected OECD countries

In this paper we examine the role of environmental quality in determining per capita health expenditures. We take a panel cointegration approach in order to explore the possibility of estimating both short-run and long-run impacts of environmental quality. Our empirical analysis is based on eight OECD countries, namely Austria, Denmark, Iceland, Ireland, Norway, Spain, Switzerland, and the UK for the period 1980-1999. We find that per capita health expenditure, per capita income, carbon monoxide emissions, sulphur oxide emissions and nitrogen oxide emissions are panel cointegrated. While short-run elasticities reveal that income and carbon monoxide emissions exert a statistically significant positive effect on health expenditures, in the long-run in addition to income and carbon monoxide, we find that sulphur oxide emissions have a statistically significant positive impact on health expenditures.     

Consumption patterns in Sri Lanka: a decomposition analysis

Knowing consumer reaction to changes in prices and income is important in formulating microeconomic policies, such as public utility prices and commodity taxation. This paper analyses the consumption patterns of consumer goods grouped into eight broad commodities in Sri Lanka during the period 1975–2016, using a system-wide framework. The analysis indicates that Sri Lankan consumers allocate more than half of their income to food and nearly four fifths of their income to food, housing, and transport combined. The estimated income and own-price elasticities reveal that food, housing, medical care, and transport are necessities; clothing, durables and recreation are luxuries; and demand for all commodities is price inelastic except for recreation. To investigate the consumption growth pattern, we decomposed the growth in consumption and change in budget shares of the eight commodities into income, relative price, and change in taste. We also simulated per capita consumption expenditure of the eight commodities under various policy scenarios and found that income growth has played a significant role in Sri Lankan consumption patterns.     

REAL PRODUCT AND PRICE COMPARISONS BETWEEN LATIN AMERICA AND THE REST OF THE WORLD

The purpose of this article is to add 12 Latin American countries to the Phase III of the United National International Comparisons Project (ICP). The data for Latin America was obtained through ECIEL. It has been demonstrated that the exchange rates do not usually reflect the relative purchasing power of currencies. When low-income countries are compared to higher income countries the exchange rate conversion tends to understate the relative income of the lower income countries. This is true for the total GDP and even more so for the GDP components. In per capita terms it is found that for low income countries their income is more than twice as great as is indicated by the exchange rate conversion.

Firm turnover,restructuring and labour productivity in transition: the case of Poland

Many studies have found strong and positive relationship between per capita income and health care expenditure. These studies usually adopt the assumptions that (1) the relationships among the variables are constant; and/or (2) the supply-side market for health care could be treated by using standard demand functions models. To take into account of the supply side of health care, we use the demand and supply approach with the cointegration model to re-examine this issue. By using Taiwan health care expenditure data, our results show that the real income elasticity is smaller than unity and the health care expenditures are primarily for ‘curing’ rather than ‘caring’.     

Demand in New Zealand hospitals: expect the unexpected?

The health care sector in New Zealand has undergone substantial structural reform since 1983 and stands out relative to other OECD countries, with relatively low per capita health expenditure and a high share of public funding. Efficient allocation of resources in this public dominant health system is therefore paramount. This article uses a national database of hospital admissions to predict hospital demand. We find lagged information on patient demand imperative in formulating an easy to implement approach for predictive purposes. Contrasting predicted with actual demand, we construct an indicator of volatility in unexpected patient demand (at both the hospital and the disease chapter level) and assess its role with regard to patient outcomes. There is consistent evidence that when actual patient numbers exceed predicted, patients stay in hospital significantly longer and are more likely to have an acute readmission.     

Nonhomothetic Preferences and International Trade

This study examines whether nonhomothetic preferences underlie the “missing trade” problem associated with factor content of trade models. We first find that per capita income goes a long way in explaining differences in goods consumption across countries. We then find a striking correlation between the factor content of consumption and per capita income, and show that accounting for this is a key part of resolving the case of the missing trade. However, nonhomothetic preferences over broad categories of expenditure play only a small role in this phenomenon. Rather, we find that as income grows, spending is directed towards the relatively capital‐intensive version of a given good. Since recent research shows that capital intensity is correlated with quality ( Schott, 2004 ), our results suggest that within‐product quality differences are likely important for explaining the factor content of trade, whereas nonhomothetic preferences over broad categories of expenditure are much less so.

Heterogeneity and the evaluation of efficiency: the case of Italian universities

This study investigates the quarterly relationship between the quantity of cigarettes sold, real disposable income per capita, and the relative price level of cigarettes in Canada. Careful attention is paid to the nonstationarity of the data and the dynamic specification of the model. It is concluded that cigarette demand is extremely insensitive to price and income changes. This is evidence of the large consumer surplus smokers enjoy and the large revenue increasing potential of a cigarette tax increase policy, as opposed to cigarette bans.     

Is health care a luxury? The debate revisited with new evidence from emerging economies

This paper studies the long-run relationship between health care expenditure and income using a panel data set of emerging economies over the period 1995–2012. The results show that expenditure on health care and income are non-stationary and cointegrated. After controlling for cross-sectional dependence and unobserved heterogeneity among different countries, we find that the income elasticity of health care is less than 1, indicating that health care is a necessity and not a luxury. Government expenditure and out-of-pocket expenditure turn out to be important determinants of health care expenditure. Among non-monetary factors, results show that old age dependency and female education seem to have significant bearings on health care expenditures. Policy recommendations suggest that government should increase spending on health care in emerging economies since higher incomes may not automatically translate into higher health care spending by the people of these countries.     

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.     

A Decomposition Analysis of Regional Poverty in Russia

The paper applies a new decomposition technique to the study of variations in poverty across the regions of Russia. The procedure, which is based on the Shapley value in cooperative game theory, allows the deviation in regional poverty levels from the all‐Russia average to be attributed to three proximate sources: per capita income, inequality, and local prices. Contrary to expectation, regional poverty variations turn out to be due more to differences in inequality across regions than to differences in real income per capita. However, when real income per capita is split into nominal income and price components, differences in nominal incomes emerge as more important than either inequality or price effects for the majority of regions.
