Factor Components of Inequality: A Cross‐Country Study

This paper uses data from the Luxembourg Income Study to examine some of the forces that have driven changes in household income inequality over the last three decades of the twentieth century. We decompose inequality for six countries (Canada, Germany, Norway, Sweden, the U.K., and the U.S.) into the three sources of market income (earnings, property income, and income from self‐employment) and taxes and transfers. Our findings indicate that although changes in the distribution of earnings are an important force behind recent trends, they are not the only one. Greater earnings dispersion has in some cases been accompanied by a reduction in the share of earnings which dampened its impact on overall household income inequality. In some countries the contribution of self‐employment income to inequality has been on the rise, while in others, increases in inequality in capital income account for a substantial fraction of the observed distributional changes.     

Conflict and inflation in industrial countries

This paper examines expirically the conflict theory of inflation, using a sample of pooled time-series, cross-section data over the period 1971–87 for 10 industrial countries: USA, Japan, Canada, Germany, France, UK, Italy, Belgium, Netherlands and Sweden. To this end a wage-price adjustment model based on the ideas of distributional conflict in wage formation and mark-up pricing in goods markets is set out. The model provides a satisfactory explanation of the inflationary process in industrial countries. It is shown that conflict between workers and capitalists over the distribution of income exerts a significant influence on the pattern of inflation. Import prices, inflationary expectations and labour market conditions are also important, with the latter acting as a regulator of class conflict.     

Is ex‐ante ex‐post analysis irrelevant to Keynes's theory of employment?

Ex‐ante ex‐post analysis has become a standard tool in macroeconomics. Yet Keynes dismissed it. We argue that Keynes's dismissal of ex‐ante ex‐post analysis is not an oddity but an indication of the originality of his theory of employment compared to standard macroeconomics. First, the principle of effective demand does not amount to a process that determines employment and income at the point of intersection of the traditionally defined ex ante supply and demand functions. Second, the finance motive allowed Keynes to confirm the identity of aggregate supply and demand already asserted in The General Theory. This latter conclusion is puzzling, however, since the principle of effective demand presupposes the possibility of a discrepancy between supply and demand. We suggest that Keynes's theory of employment is linked to a theory of income distribution whereby profits are a redistributed share of factor income which is transferred to firms when prices exceed factor costs. The identity and the equilibrium condition then relate to separate measurements of income and output, factor cost and prices.     

Taxes,female labour supply and household income: differences between the Netherlands and the Federal Republic of Germany

The article investigates the effect of taxes and social premiums on female labour supply and household income. A comparison is made between labour supply and household income between the Netherlands and the Federal Republic of Germany in 1992. A discrete choice model for labour supply is used in which taxes and social premiums are implicitly incorporated. As male labour supply is highly inelastic an individual, male chauvinist model is used. The estimated models are used to simulate the effect of the differences in the tax and social premium system on the differences in labour supply and income between both countries. The results indicate that labour force participation is higher the more individualized the system. The German system leads to a lower tax burden compared to the Dutch system. It is concluded that differences in the tax and social premium system between both countries have hardly any influence on the differences in the inequality of net household labour income. There is evidence that the German system leads to a slightly more unequal distribution of household income. It is also concluded that although the tax and social premium system does influence labour supply and income, it can be doubted whether these effects are substantial.     

BILATERAL TRADE RELATIONSHIP BETWEEN THE UNITED STATES AND CANADA: IMPLICATIONS OF THE FREE TRADE AGREEMENT

This study's primary objective is to evaluate empirically the economic effects of the U.S.-Canada Free Trade Agreement (FTA). The paper emphasizes bilateral trade flows of agricultural and industrial products between the United States and Canada, given that the FTA removes tariff and non-tariff barriers. It evaluates the FTA's impact on the two countries' trade with third countries. The paper specifies a traditional log-linear trade model consisting of import demand and export supply equations for both agricultural and industrial products. It uses quarterly time-series U.S. and Canadian trade data for 1972–1985.
The study uses the two-stage least-squares estimator to estimate the models. The models had R coefficients ranging from 0.78 to 0.99, indicating that the models' explanatory variables explain most causes of variations in the dependent variable. This study reveals that U.S. imports of agricultural and industrial products from Canada were more sensitive than were Canadian imports not only to import and domestic prices but also to world prices. This is because Canadian consumers have less domestic substitutes than do their U.S. counterparts. Also, Canada has a smaller internal market than does the United States. The study estimates that U.S. imports from Canada will increase $2.8 billion while Canadian imports from the United States will increase $1.2 billion. The impact on the two countries' trade with third-party countries will be insignificant.     

Shadow pricing of labour and capital in an economy with unemployed labour

This paper derives the shadow prices of labour and capital to be used in the public sector in a situation of unemployment. The setting considered is that of a three-good, two-period general equilibrium model. Then shadow prices are compared to their corresponding market prices and shown to closely depend on own and cross-elasticities of supply and demand for labour and investment. In the first part, a rigid wage rate is the sole source of distortion; then, a tax on capital income is introduced so that our formula for the social rate of discount can be contrasted with that of Harberger, Sandmo and Drèze.     

The effects of rising labour costs on global supply chains: the case of China’s cotton yarn industry

Rapid economic growth in China and India has resulted in rapidly rising labour costs in those countries. In this study a Muth-type model is used to assess the potential effects of this development on global supply chains using China’s cotton yarn industry as a case study. The model considers i) product differentiation at the yarn level; ii) imperfect competition in the markets for cotton yarn and raw cotton fibre, iii) input substitution between raw cotton fibre, labour, and capital; and iv) offsetting increases in the demand for cotton yarn caused by rising consumer income. Results suggest the effects of rising labour costs on the supply chain are modest, and easily swamped or obscured by the effects of rising income. Increases in industry market power (both oligopoly and oligopsony) have the same effect on the supply chain as increases in labour costs, raising prices to consumers of cotton yarn, and lowering prices to input suppliers, including foreign suppliers of raw cotton fibre. The combined effects of increases in labour costs and income have increased the factor shares for labour and to a lesser extent capital at the expense of raw cotton fibre.     

Price–value deviations: further evidence from input–output data of Japan

This paper subjects to empirical testing the labour theory of value using input–output data from the economy of Japan for the years 1970, 1975, 1980, 1985 and 1990. The results of the analysis show that labour values and prices of production are extremely good approximations to market prices. In fact, the proximity of prices of production to market prices is closer than that of labour values, a result which suggests that prices of production constitute more concrete centres of gravitation for market prices. Furthermore, we find that prices of production change as a result of variations in income distribution more often than not in a monotonic way and that in fewer cases they display curvatures, which may even reverse the order between prices of production and values.     

Seasonal U.S. beer demand: socio-economic determinants and relation with other products

This article employs quarterly U.S. state-level data from 2009 to 2015 to estimate the demand for beer. Other contributions of this work involve the incorporation of demographic factors and wine prices. Results show beer demand to be inelastic, and beer and wine to be substitutes. Further, males, whites, and blacks were, ceteris paribus, likely to have greater beer demand. The income effects, however, were mixed, showing some support for beer being a normal good.     

Joint Allocation of Leisure and Consumption Commodities: A Japanese Extended Consumer Demand System 1979—90

In this study we estimate the parameters of a household expenditure function which includes joint choice of leisure and consumption commodities in scope without a separability assumption. We have used Japanese prices, wage rate, labour supply, and expenditure data on ten commodity groups, collected from 47 cities over 12 years. This data set has the advantage that separate observations are available for each data point for all the variables. We employed the AI demand system, for estimation. Controlling for time-specific effects, the result implied a definite rejection of the weak separability of labour supply and commodity choice, and non-rejection of the homogeneity and symmetry restrictions on the demand system. All the own-price elasticities are significantly negative, and both substitutes and complements are observed across commodity groups. As for the negativity, all but one of the eigenvalues of the substitution matrix are negative. The result as a whole showed consistency with demand theory. The estimated compensated labour supply elasticity is 0.39, which is in reasonable agreement with the previous studies.     

The contemporaneous correlation between price shocks and output shocks

Until the 1990s, prices were believed to be procyclical. Several researchers have since presented evidence of counter-cyclical prices. This evidence proved robust, but its interpretation has varied. Some have argued that the contemporaneous correlation between output and prices reflects both the source of the current shock and the adjustment process from short-run to long-run equilibrium; the adjustment to the long run imparts a bias towards a negative price-output correlation. The issue of dynamics is addressed by estimating price shocks and output shocks. The sign of the correlation between these shocks does not reveal anything about the relative importance or frequency of demand versus supply shocks; however, some understanding is gained from the time-series of the product of the shocks. In periods when the product is negative, supply shocks must have been either relatively large or relatively important. In periods when the product is positive, demand shocks must have been either relatively large or relatively important. The data suggest that the economies of the USA, Canada and the UK were buffeted by both demand and supply shocks in about equal portions.     

Does a lower (higher) labour force participation rate imply greater (lower) income tax evasion? An exploratory empirical inquiry for the U.S.

This exploratory study seeks to add to the income tax evasion literature by investigating a heretofore ignored potential determinant of aggregate federal personal income tax evasion in the U.S., namely, the labour force participation rate. It is hypothesized that the higher (lower) the labour force participation rate, the lower (greater) the degree of tax evasion. The empirical estimation supports this hypothesis, finding that a one unit (one percentage point) increase (decrease) in the labour force participation rate leads to a 9.1% decrease (increase) in income tax evasion. Thus, the declining labour force participation in recent years implies increased tax evasion problems for the U.S.     

TRADE CREATION AND DIVERSION EFFECTS OF THE U.S.-CANADIAN FREE TRADE AGREEMENT

This study empirically estimates and evaluates the economic benefits of the U.S. and Canadian Free Trade Agreement (FTA). Most past studies rely on aggregate data. The analysis here emphasizes the trade effects of removing tariff and nontariff barriers on each commodity group classified by the Standard International Trade Classification. Estimating the amount of trade expansion under FTA for both countries involves using the import demand elasticities from a dynamic demand model. Results show that U.S. imports from Canada are more sensitive to domestic, import, and world prices than are Canadian imports from the United States. U.S. imports from Canada would increase roughly £3.257 billion compared to the £2.432 billion increase for Canadian imports from the United States .

The role of labour demand elasticities in tax incidence analysis with heterogeneous labour

Whether labour bears full burden of household level income and consumption taxes ultimately depends on the degree of substitutability among different types of labour in production. We find more variation in incidence patterns across households with less than perfectly substitutable heterogeneous labour than with perfectly substitutable homogeneous labour in production. This finding is based on results obtained from homogeneous and heterogeneous labour general equilibrium tax models calibrated to decile level income and consumption distribution data of UK households for the year 1994. We use labour supply elasticities implied by the substitution elasticity in households' utility functions and derive labour demand elasticities from the substitution elasticity in the production function.

Optimal Taxation with a Trade-off Between Income and Children

This paper explores the implications of endogenous fertility for optimal redistributive taxation in the presence of a trade-off between labour income and children. The labour supply is a decreasing function of the desired quantity and quality of children. Since children enter into the parent's budget constraint in a nonlinear form, their shadow prices are directly distorted by the income tax rate. It is shown that the substitution effects of the income tax rate on the quantity and quality of children cannot be signed uniquely although the effect on labour supply is negative. The aggregate substitution effect of the income tax rate on the quantity of children plays an important role in the determination of the signs of the income tax and child subsidy rates at a Rawlsian or Benthamite social welfare optimum.

Female labour supply in Australia: Another example of a backward-bending labour supply curve

Hours worked by employed married females in Australia are analysed using techniques to correct for sample selection bias. Consistent with the conclusions of the study of female labour supply in the U.S. and Canada by Nakamura and Nakamura (1981), working wives work fewer hours per week when paid higher hourly wage rates.     

The labour market and the distribution of earnings: an empirical analysis for Italy

Using four waves of data from the Participation Labour Unemployment Survey, a database of information on the Italian labour market supply, we address the question of earnings dispersion by applying a ‘nested’ decomposition procedure of the Theil inequality measure, which combines into a unified framework the standard decompositions by population subgroups and income sources. The empirical evidence obtained points to the key role played by the self-employees in shaping labour income inequality, especially at the upper extreme of the earnings distribution, and the emergence of non-standard forms of employment as an important feature of the contemporary workplace.     

FAMILY INCOME,AGE, AND SIZE OF UNIT: SELECTED INTERNATIONAL COMPARISONS*

Two aspects of the relationship between family unit income and the age of the head of the family unit are examined in this exploratory paper. First, in connection with the recent discussion in the U.S. about the “fair” level of income of the aged population, the economic well-being of various age of head groups is examined for the U.S., Canada, Norway, and Israel. Problems inherent in comparing income distributions across countries are described briefly, and the sensitivity of the estimates to definitional differences is discussed. Relative incomes of the different age groups are then compared within and between countries. Relative mean incomes, relative median incomes, relative mean incomes adjusted for size of unit in alternative ways, distributions of age groups among income quintiles, and relative income shares within age groups are compared. The focus is on aged units. It is found that, using these crude measures, aged units in the U.S. are roughly as well off relative to the other age groups as aged groups in the other countries examined. In the second section of the paper, a U.S. microdata file is reweighted to be consistent with the distributions by age of head of Norway and Canada. Relative income shares of quintiles are computed before and after reweighting and compared with the shares for Norway and Canada. The reweighting to Norway's age distribution increased differences in relative income shares between the two countries; the reweighting to Canada's age distribution slightly decreased differences.     

Housing Prices in Urban China as Determined by Demand and Supply

This paper studies the demand for and supply of residential housing in urban China since the late 1980s when the urban housing market became commercialized. Using aggregated annual data from 1987 to 2012 in a simultaneous equations framework we show that the rapid increase in the urban residential housing price can be well explained by the forces of demand and supply, with income determining demand and cost of construction affecting supply. We find the income elasticity of demand for urban housing to be approximately 1, the price elasticity of demand to be approximately ?1.1 and the price elasticity of supply of the total housing stock to be approximately 0.5. The resulting long‐run effect of income on urban housing prices in elasticity terms is approximately 0.7, because the increase in income has shifted the demand curve outward more rapidly than the supply curve.
