The political economy of corporatism in medicine: Self-regulation or cartel management?

This paper seeks to explain why delegation of regulatory authority to medical associations (medical Corporatism) is so prominent in health care. It argues that the interests of politicians and physicians in limiting access to medical markets rather than the interests of patients in the control of quality of medical care determines this delegation. Recent trends in physician densities, their impacts on physician incomes, and rates of return to a medical career in several industrialized countries are adduced as evidence to support this claim.     

STOCHASTIC PROCESS MODELS AND THE DISTRIBUTION OF EARNINGS*

This article examines several hypotheses concerning the stochastic nature of year to year variations in individual incomes in light of newly available microdata on individual earnings. In particular, the models of Solow (1951), Champernowne (1953), and Rutherford (1955) are examined in some detail, and their predictions as to changes to be expected in the distribution of individual incomes are tested. The author concludes that the distributions arrived at using these models are not very similar either to each other or to the actual distribution of earnings. Thus, he believes that as an “explanation” of earnings dynamics stochastic process models are unsatisfactory. He further criticizes these models on the grounds that they foster a bias toward the belief in the inevitability, and perhaps desirability, of the current distribution of earnings.     

A net impact analysis of active labour programmes in Hungary

This paper presents estimates of the impact on re-employment and earnings of the two most popular active labour programmes used during the economic transition in Hungary: retraining and public service employment (PSE). To adjust for non-random assignment of programme participants, net impacts were computed using matched pair samples and regression models. The evidence suggests retraining may improve the chance for reemployment, is unlikely to improve re-employment earnings, but may improve job durability. Net societal benefits could be improved by retraining relatively more males, older persons, and those with less education. PSE does not appear to provide a reliable path to a regular non-subsidized job, and may even lower re-employment earnings. PSE might best be viewed as an income transfer programme having the collateral benefit of maintaining basic work habits. The net societal impact of PSE could increase if it involved relatively more females and older persons.     

SIZE-DISTRIBUTION OF EARNINGS AND HOUSEHOLD INCOMES IN SMALL SOCIALIST COUNTRIES

Part I: Availability and meaning of East European distributional statistics are discussed. Part II: Measures of inequality to be used in this study are examined: the Gini coefficient of concentration, though superior to some other single indicators, is found to be an unreliable comparative measure of inequality, and is therefore supplemented by a set of ratios of selected percentiles to the median. Part III: Inequality of full-time gross monthly earnings is measured for (almost) the whole civilian working population and for some subpopulations (selected industries, men, women) in Czechoslovakia and Yugoslavia through 1970, in Hungary through 1968: the observed inequality appears to be less than in small capitalist countries, in spite of the reversal of the socialist egalitarian trend in the 'sixties. The main factor of equalization of socialist earnings are small interoccupational and interregional differentials and a very flat age profile. Part IV: The socio-economic structure of households, the size of samples underlying the distributional statistics, and the composition of household “revenues” (wage and salary earnings, agricultural incomes, social security payments, relatively unimportant property incomes, as well as non-income cash flows) are examined. Inequality coefficients are estimated for per capita revenues of all households as well as subpopulations of households in Czechoslovakia and Hungary, and some information is given on the distribution of household incomes in Yugoslavia. Part V: Limits of desirable equalization of earnings are discussed. With very narrowly dispersed short-term earnings, lifetime earnings tend to be rather unequally distributed because of the variation of earning years among occupations. With largely equalized primary incomes, per capita household incomes tend to be more unequally distributed, in spite of massive transfers, because of the varying ratio of earners to dependents within households. The need of income differentials as incentives to work, the probable trade-off between income equality and economic growth, and socialist distributive principles are outlined.     

The Practice Boundaries of Advanced Practice Nurses: An Economic and Legal Analysis

The purpose of this study is to examine the effects of State regulation that determines the extent of professional independence of advanced practice nurses (APNs). We find that in States where APNs have acquired a substantial amount of professional independence, the earnings of APNs are substantially lower, and those of physicians assistants (PAs) are substantially higher, than in other States. These results are striking since PAs are in direct competition with APNs; the only real operational difference between these groups is that PAs are salaried employees who must work under the supervision of a physician. The implication is that physicians have responded to an increase in professional independence of APNs by hiring fewer APNs and more PAs. The finding that earnings of APNs decline when they attain more professional autonomy vis-à-vis physicians reinforces work by Sass and Nichols on physical therapists.The content is the responsibility of the authors and does not represent official positions of the Federal Reserve Bank of St. Louis or the Federal Reserve SystemJEL classification: I11, I18, J31, J44, L51     

WELFARE REFORM, EARNINGS, AND INCOMES: NEW EVIDENCE FROM THE SURVEY OF PROGRAM DYNAMICS

The authors ask how welfare reform has affected the earnings and incomes of welfare recipients using a detailed longitudinal data set, the recently released Survey of Program Dynamics (SPD). They find pre-TANF waivers positively affected the earnings and incomes of both female high school graduates and nongraduates, but the effect is statistically significant only for nongraduates. In contrast, the effect of TANF policies is detrimental to nongraduates but improves economic outcomes for graduates. The findings indicate there are still families who are left behind by welfare programs. The results also warrant further use of longitudinal data sets such as the SPD. (JEL I38 , H53 )     

JOB DISPLACEMENT AND THE INTER‐TEMPORAL MOVEMENT OF WORKERS THROUGH THE EARNINGS AND INCOME DISTRIBUTIONS

This paper uses the Panel Study of Income Dynamics to examine how job displacement influences intragenerational earnings and income mobility. Job displacement increases the probability of downward labor earnings mobility for several years after separation occurs. Furthermore, the probability of being in the bottom half of the earnings distribution increases significantly, not only in the year of displacement, but also for several years afterwards. However, after considering additional measures of financial well‐being (income from other family members and government transfer payments), the short‐ and long‐term impact of displacement on movements throughout the distribution is reduced.

Equity vs. efficiency vs. self-interest: on the use of dictator games to measure distributional preferences

We conduct modified dictator games in which price of giving varies across choice situations, and examine responses to price changes in two contexts—one where dictators divide their own earnings, and another where they divide the earnings of others. Varying the price of giving allows us to decompose social preferences into two components: the level of altruism when the price of giving is one, and the willingness to reduce aggregate payoffs to enhance equity. Changing the source of a dictator’s budget impacts her decisions because it affects the weight that she places on others’ payoffs. However, we find no impacts on the willingness to trade off equity and efficiency.     

The impact of job mobility on earnings: using occupational and industrial classifications to identify job changes

According to the Bureau of Labor Statistics, the median number of years that a US worker has been with their current employer is 4.4 years. Although many job changes may not be classified as ‘career changes,’ any type of job change may have an impact on a person’s future earnings. In the present study, the following three types of job changes are examined in order to determine which ones result in higher incomes: a change in occupational status; a change in industry; or a change in both. Using data from the National Longitudinal Survey of Youth (NLSY), a log-linear wage regression with a correction for self-selection is estimated. Results suggest that changing jobs within the same industry or within the same occupation both increase a person’s income. However, a job change that is characterized by both a change in industry and occupation reduces a person’s income. The present study is one of the few studies to examine the effects of job mobility on earnings when mobility is defined in the context of changes in occupational and/or industrial classification.     

The effect of commute time on racial earnings inequality: a case study of the Houston metropolitan statistical area

Data from the United States Census confirm a substantial increase in the racial earnings gap between 1980 and 1990. This paper examines data on whites and non-white wage and salary incomes in Houston TX for 1980 and 1990. Data on time travelled to work is used to simulate what would be the impact of shorter commute times on earnings inequality. The central finding is that a reduction in travel time from residence to work would cause a very small reduction in racial earnings and income inequality. This suggests that advances in urban transportation policy alone are not sufficient to solve the problem of racial earnings inequality.     

EFFECTS OF DRUG ABUSE TREATMENT ON LEGAL AND ILLEGAL EARNINGS

Although recent research has shown that drug abuse treatment reduces drug use and criminal activity in some clients, the impact of treatment on clients' post-treatment labor market behavior is relatively unknown. This study uses data from a longitudinal survey to analyze annual legal and illegal earnings for 2,420 drug abusers. The analysis focuses on two different time intervals—one year before entering a drug abuse treatment program and one year after leaving the same program. It describes client characteristics, labor market variables, and treatment history, and estimates the effects of length of time in treatment on post-treatment earnings. The regression analysis shows that length of time in treatment had a positive (negative) and statistically significant impact on real legal (illegal) earnings following treatment for methadone and residential clients, but the magnitude was small; accounting for possible selection bias had little effect on the results. Although residential clients experienced the largest relative changes in earnings outcomes, simply comparing the direct cost of residential treatment with the benefits from improved legal earnings and lower illegal earnings suggests that additional residential treatment is not cost-beneficial.     

HIGH AND LOW EARNINGS JOBS: THE FORTUNES OF EMPLOYERS AND WORKERS

The focus of the literature on the effect of job changes has been on the consequences of job destruction on the individual worker. In this paper we analyze the impact on the earnings distribution of both job creation and job destruction. We establish a link between job reallocation and the movement of workers into and out of the tails of the earnings distribution. Both job creating and job destroying employers shed jobs mostly from the middle and lower tails of the earnings distribution, although this is cyclically very sensitive. Labor mobility (triggered by job reallocation) is risky: mobile workers will generally end up in the upper or lower tail of the distribution rather than in the middle. If workers move across industry boundaries, they typically move to the lower tails of the distribution. In sum, the fortunes of workers depend on the fortunes of their employers.     

Testing and applying a theory of utility: An attempt to decompose income in compensatory and scarcity rents

Data on income after tax, schooling completed, job held, age, and ‘level of satisfaction’ of 2663 members of the Dutch Consumer Union have been used to estimate regression equations of two types. Type I may be called a specification of a utility function, Type II an ‘earnings function’ (where income after tax was used as earnings). For both types a number of alternatives were estimated both with regard to mathematical shape and with regard to variables included. Defining equitable or justified income differences as differences which do not change the level of satisfaction, a formula for equitable incomes for given combinations of job, schooling and age can be derived from Type I equations. All regression coefficients are found to be lower than the corresponding earnings function coefficients. The latter can then be decomposed into a ‘compensatory’ component and a ‘scarcity rent’ component.     

The Shrinking Earnings Premium for University Graduates in Hong Kong: The Effect of Quantity or Quality?

In 1989, the Hong Kong government embarked on a program to increase the provision of first-year first-degree places. The expansion of tertiary education represents a large and exogenous increase in the supply of university graduates to the territory. This article measures the labor market effects of the expansion program by studying the changes in earnings premium for university graduates. Two alternative hypotheses—crowding and quality effects—are identified to explain why the earnings premium shrank. The results support the view that the declining quality of university graduates is the prime candidate for the declining earnings premium. (JEL J31 , I28 , J18 )     

The changing role of education in the distribution of earnings and household income

This article draws on income surveys from the last two decades to report on trends in earnings disparities and household income inequality in the Czech Republic. Education has been the main axis of change in this area, having acquired a much greater role in the entire process of collecting and distributing income. First, an increasing influence of education is evident in the personal earnings of employees, returns to education having doubled. Second, in couples, education has an important impact on both women’s employment and their earnings. Third, the importance of marital partners’ education levels on household income grew even more than its effect on earnings.     

OCCUPATIONAL EARNINGS BEHAVIOR AND THE INEQUALITY OF EARNINGS BY SEX AND RACE IN THE UNITED STATES*

This paper examines differences in earnings by occupations, and within occupations by sex and by race, on the basis of the 1/100 Public Use Samples of the 1960 and 1970 U.S. Population Censuses. It employs interval analysis to establish 32 categories of occupations with similar characteristics. Little relation was found between mean earnings of occupational groups and the degree of earnings inequality within them. When the figures are examined by sex, it was found that men, on average, earned over twice as much as women in both years, but women's earnings were more unequally distributed (as measured by the Gini coefficient). Women are concentrated in the traditional “female” occupations, which tend to be those at the bottom of the earnings scale, and men have a monopoly of the higher paid occupations. But mean earnings for men exceeded those for women in all occupational groups except one, even in the primarily female occupations. Standardizing first for occupational distribution and then for earnings by occupation, it was found that earnings differences between males and females within occupation had a greater impact on the overall male-female earnings ratio than did differences in occupational distribution by sex. In contrast, when the figures are examined by race, the change in occupational distribution (primarily the movement of blacks out of farming and of blacks and Spanish speakers out of personal services) was the major factor. There was also a considerable degree of earnings inequality within demographic groups. The degree of inequality was in the main reduced when the demographic groups were subdivided into occupations, but it was still substantial. Additional factors like time worked, schooling, and experience must be taken into consideration in understanding this phenomenon.     

CROSS-NATIONAL DIFFERENCES IN INCOME MOBILITY: EVIDENCE FROM CANADA, THE UNITED STATES, GREAT BRITAIN AND GERMANY

Using a standardized dataset, this paper compares the differences in income mobility among four countries—Canada, the United States, Great Britain and Germany—during the 1990s and early 2000s. The results suggest that, in general, there exist diverse levels of income mobility across the four countries. Although the precise magnitudes of the differences are sensitive to the measurement method used, incomes in Britain are by far the most mobile. Our findings also reveal country-specific driving forces that underlie income mobility. The stabilizing effects of government transfers are most pronounced in Canada. In Germany, it is the progressive tax system that offsets earnings variations and results in smaller changes in longitudinal incomes. Moreover, we also discover that demographic factors provided only limited explanation of differences in income mobility.     

Transfers among divorced couples: evidence and interpretation

An analysis of the economic impact of divorce settlements in the United States is presented using data for a white cohort taken from the National Longitudinal Study of the High School Class of 1972. "The effects of spouses' incomes on the divorce transfer are estimated and used to simulate the welfare effects of divorce on husbands, wives, and children under alternative assumptions about marriage contracts and the ability of a couple to continue coordinating resources in the aftermath of divorce. We find a positive (negative) relationship between divorce transfers and the growth of husband's (wife's) earnings during marriage. The estimated expenditure on children in the divorce state is only half the accustomed level during marriage."     

THE IMPACT OF FINANCIAL HELP AND GIFTS ON HOUSING DEMAND AND COST BURDENS

Financial transfers are an important source of income for many households and recipients may use these funds to pay for housing services. This paper examines the separate impact of financial help and substantial gifts on both housing demand and housing cost burden. The results indicate receiving gifts has a positive and statistically significant impact on housing demand. Households receiving help or gifts have substantially higher housing cost burdens, all else being held constant. These findings have implications for the financial well-being of recipient households and ultimately, the mortgage industry . ( JEL R20, R21)     

How much do immigration and trade affect labor market outcomes?

"This paper provides new estimates of the impact of immigration and trade on the U.S. labor market.... We examine the relation between economic outcomes for native workers and immigrant flows to regional labor markets.... We...use the factor proportions approach to examine the contributions of immigration and trade to recent changes in U.S. educational wage differentials and attempt to provide a broader assessment of the impact of immigration on the incomes of U.S. natives."
