How to compare apples and oragnes: Poverty measurement based on different definitions of consumption [статья]
Опубликовано на портале: 12-12-2002Jean Olson Lanjouw, Peter Lanjouw Review of Income and Wealth. 2001. Vol. 47. No. 2.
Poverty rates calculated on the basis of household consumption expenditures are routinely compared across countries and time. The surveys which underlie these comparisons typically differ in the types of food and non-food expenditures included, often in ways which are easily overlooked by analysts. With several examples we demonstrate that these commonly occurring variations in expenditures definitions can give rise to marked differences in poverty rates where there are no real differences in well-being. We show that one approach to calculating poverty lines, used with headcount measurement of poverty, can allow comparisons based on data with different definitions of consumption. In addition to allowing comparative poverty analysis using existing survey data, the results suggest that poverty monitoring could be done effectively at lower cost by alternating detailed expenditures surveys with far more abbreviated surveys.

Using the national income/expenditure distribution data from 111 countries, we decompose total inequality between the individuals in the world, by continents and regions. We use Yitzhakis Gini decomposition which allows for an exact breakdown of the Gini. We find t hat Asia is the most heterogeneous continents; between-country inequality is much more important than inequality in incomes within countries. At the other extreme is Latin America where differences between the countries are small, but inequalities within the countries are large. Western Europe/North America is fairly homogeneous both in terms of countries mean incomes and income differences between individuals. If we divided the world population into three groups: The rich (those with incomes greater than Italys mean income), the poor (those with income less than Western countries poverty lie), and the middle class, we find that there are only 11 percent of people who are world middle class; 78 percent are poor, and 11 percent are rich.

The paper describes how two related software packages can be applied for producing safe data. The package - ARGUS is used for tabular data and its twin w-ARGUS for microdata. The main techniques used to protect sensitive information are global recoding and local suppression. Bona fide researchers who need more information have the possibility to visit Statistics Netherlands and work on-site in a secure area within Statistics Netherlands. Some examples are given of official statistics that have benefited from statistical disclosure control techniques.

This study critically evaluates alternative estimates of China's GDP level and growth, as well as its PPP GDP conversions, and, based on this evaluation, it draws important implications for the understanding of China's economic performance in both historical and international perspectives. It finds that although almost all empirical results have supported the downward-bias hypothesis for China's GDP level and the upward-bias hypothesis for China's GDP growth, they vary greatly, and that PPP estimates for China are also diversified. These estimates, if accepted, may substantially alter the existing views on the Chinese economy, particularly, its size, TFP level and catch-up performance. The discusion docuses on the theories, methodologies and data used in these studies, and particularly, the possible biases in their results thereby. It argues, however, that despite differences in estimates, they could still provide sensible boundaries for researchers to gauge the "real" values and hence assess China's "real" living standard and growth performance.

Statistics Finland has compiled waste statistics since the mid-1980s. The data material included administrative registers, surveys and research results. Waste was initially classified according to a 'Finnish' classification based on composition of waste until the mid-1990s, and later according to the European Waste Catalogue (EWC). A Guide to Waste Classification was drafted to facilitate classification in 1999. The Standard Industrial Classification (NACE) has been employed as a background classification for waste statistics. Waste statistics have been and are being used especially for preparing the national waste strategy and the waste management guidelines, in the planning stage of waste treatment plants, for research, and as supplementary material for compilation of material flow accounting.

This paper describes the major methods used by statistical agencies to adjust for differences in the quality of a good or service when one item replaces another in a sample used to construct a Consumer Price Index. The methods are categorized as either direct, including the production-cost and hedonic approaches, or indirect, such as linking or class-mean imputation. The paper also presents simplified example calculations showing how the methods are applied in practice.

In the literature of labor economics we find many examples of studies analyzing job seekers search behavior, but few examples of the corresponding analysis of the recruitment behavior of employers. This paper gives a picture of the recruitment behavior of Swedish employers. The analysis is based on about 800 telephone interviews with employers regarding the last person they had hired. This paper relates the lemons problem in Akerlof with the Spence signaling model, and then it proceeds to relate indices and signals to the hiring behavior of employers. Employers mainly recruit personnel in order to expand a certain activity of their firm. On an average the total recruitment process takes about a month. In first round employers mainly look for job seekers with good education and experience. During the job interview the employer search for persons with professional knowledge, personal engagement and social competence

In attempting to ascertain various impacts on labor market outcomes using categories such as gender, race, ethnicity, and physical ability, a void exists with respect to sexual orientation. Whereas heterosexism and homophobia can explain some of the reasons for the void, the inability to collect data randomly about homosexuals' experiences in the labor market nullifies the basic tenet of all scientific research-random samples. A unique approach is presented which looks at income data for nonrelatives of the same sex, ages 45 to 64, living together in Canada, as a first attempt at comparing same-sex and opposite-sex genders, and is used to demonstrate the contribution of recognizing sexual orientation to economic questions. Other examples based on well-known debates about female labor participation and gender wage gaps are presented to evaluate the usefulness of studying economics recognizing sexual orientation. The need for such study is acknowledged as a measure of the inclusiveness of the economics discipline.

In his economic writings John Paul II asserts the importance of placing the human person at the center of deliberations concerning the economy. Neoclassical economists show that free trade enhances the efficiency of society. However, a byproduct of free trade is greater competition, as countries and firms adjust to the introduction of new products and processes of production, made possible through technological innovation. Neoclassical economists assume that workers will move to where new jobs develop. In many cases, however, this means that they impose burdens on their family and become more distant from friends. Each human person establishes bonds with other persons; through such family bonds of friendship a person becomes more human. This essay explores the tension between greater productive efficiency and a desire to maintain and enhance friendships. Never merely objective analysts, neoclassical economists have strong convictions concerning dynamic efficiency, while consumers have convictions about friendship. These two sets of convictions have to be reconciled. In order for policy makers to assess the true costs of free trade, mobility measures must be developed, and the neoclassical model must be modified to incorporate geographical stability as a significant factor for consumers.
Establishing the Priority of Labor [статья]
Опубликовано на портале: 10-12-2002G.Paul Peterson, James A. Buss International Journal of Social Economics. 1998. Vol. 25. No. 1112. P. 1699-1710(12) .
Pope John Paul II and the social teachings of the Catholic Church emphasize that labor should not be treated as an instrument in the production process. Rather justice requires that labor be given priority over capital. The reasons for this priority are explained. Several labor market conditions are examined to show that generally the priority of labor over capital does not exist. These conditions include unemployment, unjust wages, poverty, suppression of union activities, lack of participatory management, and discrimination against women and foreign workers. The works of Pope John Paul II are examined to discern the causes of these injustices and possible remedies for them. The roles played by the indirect employer, structures of evil, the ownership of economic resources, as well as the error of economism are considered.

A hallmark of modern labor economics is the close interplay between the development of theory, data sources and econometric testing. The evolution of the economic analysis of unemployment insurance provides a good illustration. New theoretical approaches, in particular job-search theory, have inspired a large amount of empirical research, some of it methodologically innovative and most of it highly relevant for economic policy. The paper presents a broad survey and an assessment of the economic analysis of unemployment insurance as it has evolved since the 1970s.
Market Forces and Sex Discrimination [статья]
Опубликовано на портале: 08-12-2002Judith K. Hellerstein, David Neumark, Kenneth R. Troske Journal of Human Resources. 2002. Vol. 37 . No. 2 . P. 353-380.
The authors report new evidence on the existence of sex discrimination in wages and whether competitive market forces act to reduce or eliminate discrimination. Specifically, they use plant- and firm-level data to examine the relationships between profitability, growth and ownership changes, product market power, and the sex composition of a plant's or firm's workforce. Their strongest finding is that among plants with high levels of product market power, those that employ relatively more women are more profitable. No such relationship exists for plants with apparently low levels of market power. This is consistent with sex discrimination in wages in the short run in markets where plants have product market power. The authors also examine evidence on the longer-run effects of market forces on discrimination, asking whether discriminatory employers with market power are punished over time through lower growth than non-discriminatory employers, or whether discriminatory employers are bought out by non-discriminators. There was found little evidence that this occurs over a five-year period, as growth and ownership changes for plants with market power are generally not significantly related to the sex composition of a plant's workforce.
An Analysis of Occupational Change and Departures from the Labor Force: Evidence of the Reasons Teacher Quit [статья]
Опубликовано на портале: 08-12-2002Todd R. Stinebrickner Journal of Human Resources. 2002. Vol. 37 . No. 1. P. 192-216.
This article deals with two problems: the timing of exits from the teaching profession and the reasons for these exits. Approximately 67 % of exiting female teachers leave the work force altogether. The presence of a newborn child is the single most important determinant of exits for females. The paper discusses why studies of quit behavior that simply include a person's total number of children may fail to capture the true importance of fertility behavior on a female's quit decision. It is also examined in this paper the return rates of departing teachers and compares the exit behavior of teachers to that of nonteachers.

This paper examines the impact of childcare prices and wage rates on the joint employment and childcare mode (center, sitter, relative, and husband) choice decisions of married mothers by estimating both a mixed logit and universal logit choice model. Data are drawn from the 1988 Canadian National Child Care Survey and the 1988 Labour Market Activity Survey. The estimation results show that wages have a positive impact on the probability of choosing any of the working states and that childcare prices for center, sitter, and relative care reduce the probability of working and using each respective mode of care. Sensitivity analyses reveal that the wage elasticity for employment is fairly robust across model specifications, while the own-price elasticity of childcare is sensitive to model specification, differing identifying assumptions in the estimation of childcare price equations, and sample selection. The simulation results show that differences exist in the degree to which government subsidies in the form of wage subsidies, targeted childcare subsidies, or unconditional childcare subsidies, impact on labor supply decisions and decisions to substitute across different modes of care by those mothers already in the labor market.

Return to employment, after a period of unemployment, is analyzed for a large sample of Swedish occupationally disabled workers. A piece-wise constant model is used, extended to allow for Gamma heterogeneity. Three competing exits from unemployment are accounted for; regular employment, sheltered/subsidized employment and withdrawal from the labor force. The model is also generalized by accounting for differing search behavior within the population. The hazard rate is constant or slightly increasing over time, for exit to some kind of employment. However, for exit from unemployment by leaving the labor force, the hazard shows quite strong positive duration dependence. Men tend to be more probable to leave unemployment for regular employment, and less probable than women to leave the labor force. The probability of finding regular employment is smallest for workers with psychological disabilities, while high-school or university education as well as previous professional experience increases the hazard rate for regular employment. The heterogeneity due to differing search behavior appears to be at least as important as the Gamma heterogeneity. The estimated probabilities of no search for one particular exit varies, across exits and subsamples, between 0.0 and 0.4.
The Interaction Between Labor Market Policy and Monetary Policy: An Analysis of Time Inconsistency Problems. [статья]
Опубликовано на портале: 08-12-2002Еsa Johansson
This paper studies the interaction between time inconsistency problems in labor market policy and monetary policy. When both policies are discretionary, there is a positive inflation bias, whereas the bias in labor market programs may be either positive or negative. A commitment of labor market programs to zero increases inflation, as compared to the case when both labor market policy and monetary policy are discretionary. Delegation of labor market policy to a liberal labor market board may improve the discretionary outcome, even if labor market programs crowd out regular employment. A conservative central bank always reduces the social loss, even when monetary policy interacts with labor market policy.

The Swedish experiences of the 1990s provide a unique example of how large-scale active labour market programmes (ALMPs) have been used as a means to fight high unemployment. This paper discusses the mechanisms through which ALMPs affect (un)employment and surveys the empirical studies of the effects of ALMPs in Sweden. The main conclusions are: (i) there is hardly any evidence for a positive effect on matching efficiency; (ii) there are some indications of positive effects on labour force participation; (iii) subsidised employment seems to cause displacement of regular employment, whereas this appears not to be the case for labour market training; (iv) it is unclear whether or not ALMPs raise aggregate wage pressure in the economy; (v) in the 1990s, training programmes seem not to have enhanced the employment probabilities of participants, whereas some forms of subsidised employment seem to have had such effects; and (vi) youth programmes seem to have caused substantial displacement effects at the same time as the gains for participants appear uncertain. On the whole, ALMPs have probably reduced open unemployment, but also reduced regular employment. The overall policy conclusion is that ALMPs of the scale used in Sweden in the 1990s are not an efficient means of employment policy. To be effective, ALMPs should be used on a smaller scale. There should be a greater emphasis on holding down long-term unemployment in general and a smaller emphasis on youth programmes. ALMPs should not be used as a means to renew unemployment benefit eligibility.
