A CROSS-COUNTRY STUDY OF EQUIVALENCE SCALES AND EXPENDITURE INEQUALITY ON UNIT RECORD HOUSEHOLD BUDGET DATA

Inequality comparisons require equivalence scales to account for differences in household size and composition. The multiplicity of equivalence scale models makes the sensitivity of the inequality calculations to the scale used a significant policy issue. Such an investigation based on unit records of two adult households from Italy, Australia, South Africa, Thailand, Peru, Philippines, India and Tanzania was our principal motivation. The equivalence scale varies across countries and between different types of children. Inequality rankings of countries, though not the inequality decomposition between households of different composition, are robust to the equivalence scale used.     

Household Equivalence Scales: New Australian Estimates from the 1984 Household Expenditure Survey*

Equivalence scales are measures of the relative incomes required by households of different size and composition to attain a similar standard of living, and are used in analysis of consumer expenditure patterns as well as in judging the appropriateness of the structure of income maintenance payments. The paper reviews equivalence scales previously derived for Australia and presents a range of new estimates based on the 1984 Household Expenditure Survey.     

ARE EQUIVALENCE SCALES THE SAME FOR THE UNITED STATES AND CANADA?

This research uses microdata from the 1986 Statistics Canada Family Expenditure Survey and from the 1986–88 U.S. Consumer Expenditure Survey to estimate equivalence scales using a methodology which is very similar to that employed by Statistics Canada for the estimation of Low-Income Cutoffs. Employing identical sample selection criteria and identically specified models, we find that equivalence scales for the two countries are not, in general, statistically different when estimated in the same way. The larger issue is then whether the two countries should choose the same methodology for the estimation of equivalence scales.     

Consumption patterns of food,tobacco and beverages: a cross-country analysis

This study considers the consumption patterns of food, tobacco, soft drinks, and alcohol in 43 developed and developing countries. Such an analysis is important for policy issues associated with tobacco, alcohol, and soft drinks. The results show that consumers in the developing countries spend a much higher proportion of their income on food than consumers in developed countries. The proportion of expenditure allocated to the other three commodities, tobacco, alcohol, and soft drinks, are similar in the two groups of countries. On average, people around the world allocate about one quarter of their income on food, 2.6% on tobacco, 3.2% on alcohol and 1.2% on soft drinks. The income elasticity estimates reveal that food is a necessity in most countries, while tobacco and alcohol are necessities in most of the developed countries and luxuries in a majority of developing countries. Soft drinks are a luxury in a majority of the developing as well as the developed countries. The own-price elasticities show that demand for all four commodities is price inelastic in all countries.     

EQUIVALENCE SCALE SENSITIVITY OF POVERTY STATISTICS FOR THE MEMBER STATES OF THE EUROPEAN COMMUNITY

Using microdata from Household Budget Surveys of the Member States of the European Community, this paper examines the sensitivity of poverty statistics with respect to the choice of the equivalence scale. The results show that the ranking of the countries with respect to the overall poverty incidence is hardly affected when different equivalence scales are used. However, the composition of the poor population shows considerable changes when e.g. subjective equivalence scales are used instead of the OECD equivalence scale. The poverty incidence among specific household groups, such as single elderly and households with children, is particularly sensitive to the choice of the equivalence scale.     

RELATIVE INEQUALITY AND POVERTY IN GERMANY AND THE UNITED STATES USING ALTERNATIVE EQUIVALENCE SCALES

We use data from the Luxembourg Income Study to show the sensitivity of measures of relative economic well-being of persons in the U.S. and Germany using official equivalence scales and consumption-based country-specific equivalence scales developed for the two countries. Overall inequality and poverty levels are found not to be sensitive to the equivalence scale used. However, the official German equivalence scale yields quite different results from the others with respect to the relative income and poverty levels of vulnerable groups within the population, especially older single people.     

Income Inequality in Australia in an International Comparative Perspective

Earlier comparative work on income distribution has tended to suggest that Australia is characterised by less income inequality than other industrialised economies. Concerns about the quality of the Australian data used in such comparisons have led to the need for more detailed assessment of the situation. The Luxembourg Income Study has been a focus for this work by bringing together microdata sets for a range of countries and reorganising them to conform to standardised concepts and definitions. This paper builds on earlier work undertaken as part of the Luxembourg Income Study by including Australia in an international comparative analysis of income distribution and redistribution. The Australian data are those from the 1981–82 Income and Housing Survey, with income tax imputed onto the data file. Results are presented for the gross and net income distributions between both families and individuals in seven countries. A common set of equivalence scales is also used to adjust for differing family needs. The results indicate that, using several summary measures of inequality, the distribution of income in Australia is less equal than in four of the other six countries studied. Earlier research which placed Australia high on the international league table of income equality is thus not confirmed by the results.     

Empirical Study of Scapegoat Theory Paradigm in the Exchange Rate Variable in the ASEAN 5

This paper attempts to explain empirically the effect of order flow as an unobserved variable on the exchange rate movements based on the theory of scapegoat. The theory of scapegoat appears as the answer to the imbalance in the relationship between macroeconomic fundamentals and the exchange rate. To analyze the validity of this theory in Indonesia, the Philippines, Malaysia, Singapore, and Thailand (ASEAN 5), we apply the two-stage least squares method. The empirical testing generates a fact that the paradigm of scapegoat theory works for four countries, namely Indonesia, Malaysia, Singapore, and Thailand. Another finding is that the theory of scapegoat does not work for the Philippines. The implication of policy based on the results is the emphasis of policy that enables intervention in the foreign exchange market, the enhancement of monetary policy transparency in each country, as well as the management of capital flows more efficiently.     

An investigation of the effects of exchange rate volatility on exports in East Asia

This study investigates the effects of the exchange rate volatility on the export flows of Indonesia, Malaysia, Republic of Korea, Singapore, Thailand, and the Philippines during 1974–2011. Towards this goal a trade weighted real effective (rather than the bilateral) exchange rate and three different measures of volatility, i.e. obtained from an ARCH model, a GARCH model and a moving-average standard deviation measure are used in this study. Specifically, the export flows between six Asian countries and the rest of the world are investigated rather than focusing on trade with only one country. Our findings reveal that the exchange rate volatility has a significant impact on export flows in the short run as well as in the long run for all the countries in the sample. The impact in the long run is predominantly negative with the exception of Singapore, but in the short run the impact varies across countries. Moreover, our results are robust to the alternative measures of volatility used and most of the findings in the long run and short run are also robust to the crisis period.     

Is inflation targeting credible in Asia? A panel GARCH approach

We examine the relationship between inflation targeting and the behavior of the level and volatility of inflation for eight Asian countries over the period 1987–2013. In contrast to existing studies that rely upon time series methods, we employ a novel panel GARCH model that accounts for heterogeneity and interdependence across countries. Our main contribution is to shed new light on the inflation targeting credibility hypothesis based on lower inflation and inflation volatility as well as on the correlation between unanticipated inflation shocks within a panel GARCH framework. We find strong evidence of a reduction in the level of inflation that operates from the impact of actual inflation targets in the Philippines, South Korea and Thailand. We also find that the adoption of inflation targeting helped lower inflation volatility in the Philippines and South Korea. Overall, the results suggest that Asian inflation targeting regimes are more credible in terms of reducing the level of inflation than lowering inflation volatility. There is also evidence that the covariance of inflation shocks among inflation targeting and non-targeting countries tends to increase.     

Estimates of the steady state growth rates for selected Asian countries with an extended Solow model

This paper develops an extended version of the Solow (1956) growth model in which total factor productivity is assumed a function of two important externalities viz., learning by doing and openness to trade. Using this framework we show that these externalities have played an important role to improve the long run growth rates of six Asian countries viz., Singapore, Malaysia, Thailand, Hong Kong, Korea and the Philippines. A few broad policies to improve the long run growth rates of these countries are suggested.     

The role of technology development in national competitiveness — Evidence from Southeast Asian countries

Technology development (TD) plays a key role in national competitiveness (NC) by giving a country a competitive edge in our age of information. Lots of researchers have focused on specific areas of TD, such as technology transfer, technology acquisition, and technology management, in most of developed countries. To our knowledge, however, they have seldom discussed the influence of TD on other categories of NC and vice-versa in developing and less-developed countries. In this study, we examine the influences of each category of NC of TD. Southeast Asian countries are divided into three patterns by means of a cluster analysis. The results show that Singapore, Malaysia, Thailand, and Laos have the same rank on measures of TD and NC. Singapore, Thailand, the Philippines, and Laos have the same rank on measures of TD and Economic Performance. Malaysia and Thailand have the same rank on measures of TD and Management Capability. In contrast, the TD performance of Southeast Asian countries is worse than the human resources performance because of their insufficient human resources assigned to R&D. Furthermore, based on a strategic grid for comparing the relative performance, four types of country and their achievements are discussed. Singapore outperforms all Southeast Asian countries. Malaysia and Thailand have to leverage their TD resources in order to enhance their NC. The other countries are still hindered in developing the determinants of their NC. Finally, our study offers a path to the identification of how countries of each pattern should supplement their insufficient capabilities, and what are the most important issues that need to be addressed in retuning their TD policies in order to enhance their NC.     

Monetary policy synchronization in the ASEAN-5 region: an exchange rate perspective

In light of the long-standing vision of economic and monetary integration in the ASEAN (Association of Southeast Asian Nations) region and the importance of coordinating monetary policies to achieve it, the objective of this article is to assess the monetary policy synchronization among the founding members of the ASEAN, that is, Indonesia, Malaysia, the Philippines, Singapore and Thailand. Due to the importance of exchange rate movements to monetary policies, we approach this issue from a currency exchange rate perspective. Specifically, multivariate trend–cycle decomposition is employed to investigate common trends and common cycles among the exchange rates of these countries during the period 1976–2012. Our analysis reveals that the real exchange rates of Malaysia, the Philippines, Singapore and Thailand share common cycles in the short term and have common trends in the long term, but the Indonesian currency does not share these relationships. Thus, our results augur well for the synchronization of monetary policies among Malaysia, the Philippines, Singapore and Thailand. In contrast, the relatively turbulent dynamics of the Indonesian rupiah evident in frequent bouts of stark depreciation separated by periods of steady depreciation over the past three decades raise questions regarding the readiness of Indonesia for participating in a monetary alliance with the ASEAN-4 nations.     

World Agricultural Trade Reform: Implications for Australia

In this paper we assess the implications of agricultural trade reform by GATT member countries. To do this, we link two general equilibrium models, a world food trade model and the ORANI model of the Australian economy. By treating the ORANI model as an integral part of the world model, we are able to focus on the implications for Australia of world agricultural trade reform.
The findings suggest that, if price distorting agricultural policies were removed by GATT member countries, world food commodity prices would rise, some by up to 30 per cent, and world food trade expand by about a third. Australia would be a major beneficiary of these international developments, the value of its agricultural exports rising by close to 15 per cent. In 1986, this would have meant for Australia additional export earnings of around SUS750 million, as well as more rapid economic growth.     

Does globalization affect the insurance markets? Bootstrap panel Granger causality test

This study applies the bootstrap panel Granger causality test to identify whether globalization promotes insurance activity using data from Sigma reports of the Swiss Reinsurance Company of 8 Eastern Asian countries over the period of 1979–2008. Empirically, results for one-way Granger causality show the influence of insurance activity on globalization only in Japan. However, there is strong interaction causality between globalization and insurance activity in India, South Korea, and Thailand. In our research, the results show that the causality between globalization and insurance activity varies across countries under different conditions. The findings of this study could provide important policy implications for the 8 Eastern Asian countries under study, namely India, Indonesia, Japan, Malaysia, the Philippines, Singapore, South Korea, and Thailand.     

IS THERE BIAS IN COMPUTING HOUSEHOLD EQUIVALENCE SCALES?

Household equivalence scales are often used to help perform welfare comparisons across households with different demographic composition. Abstracting from the problems of value judgments and ethical standards, the use of equivalence scales to perform welfare comparisons still faces several measurement problems, namely the identification problem and the endogeneity problem. This paper introduces and estimates an unconditional demand system that simultaneously addresses these two problems. By explicitly considering the demand for leisure, and the fact the household can choose some of its demographic characteristics, we deal with the endogeneity problem and obtain consistent estimates. We identify unconditional equivalence scales by estimating the demand for endogenous demographic variables along with the demand for leisure and consumer goods. More general equivalence scales allowing for better comparability are estimated and used for welfare comparisons.     

ECONOMIC BENEFITS OF GLOBALIZATION: THE IMPACT OF ENTRY TO THE WTO ON CHINA'S GROWTH

A panel data method is used to evaluate the impact of China's accession to the WTO. Time‐series data for China, Australia, Austria, Canada, Denmark, Finland, France, Germany, the UK, Hong Kong, Singapore, Korea, Japan, the Philippines, Indonesia, Malaysia, Thailand, the USA and Taiwan are used to construct the growth path that what would have been followed had there been no entry by China to the WTO. We find that from 2002 to 2007, accession to the WTO raised China's real economic growth rate by 2.4%, its export growth rate by 13.2% and its import growth rate by 18.89% a year.     

The Usual Suspects? Productivity and Demand Shocks and Asia–Pacific Real Exchange Rates

A productivity-based model of East Asian relative prices and real exchange rates is tested using calculated productivity levels for China, Indonesia, Japan, Korea, Malaysia, Philippines, Singapore, Taiwan, and Thailand. Time-series regressions of the exchange rate on relative productivity ratios indicate such a relationship for Japan, Malaysia, and the Philippines (and Indonesia and Korea when oil prices are included). Panel regression provides slightly more encouraging results when the panel encompasses a subset of countries (Indonesia, Japan, Korea, Malaysia, and the Philippines). Neither government spending nor the terms of trade appear to be important factors.     

Equivalence Scales in an Intertemporal Setting with an Application to the Former West Germany

Equivalence scales provide answers to questions like how much a household with two children needs to spend compared to a couple to attain the same welfare level. These are important questions for child allowances, social benefits and to assess the cost of children over the life-cycle for example. We discuss equivalence scales in an intertemporal setting with uncertainty. To estimate equivalence scales we use a panel from German households (GSOEP) containing subjective data on satisfaction with life and satisfaction with income to represent the welfare level. Because satisfaction is measured on a discrete scale we use limited dependent variable models for panel data in estimation. Using satisfaction with life data we find that larger households do not need any additional income to be as satisfied as a couple. Using satisfaction with income, however, yields equivalence scales that increase with household size.     

A cross-country analysis of divisia variances of quantities and budget shares

Divisia variances of quantities consumed and budget shares for 105 pairs of countries are analyzed in terms of real-income, relative-price, and residual effects. One result is that luxuries tend to be more expensive relative to necessities in richer countries. The relatively low price of food in rich countries is an important factor for this result.
