TIME‐INCONSISTENCY AND WELFARE PROGRAM PARTICIPATION: EVIDENCE FROM THE NLSY*

We empirically implement a dynamic structural model of labor supply and welfare program participation for agents with potentially time‐inconsistent preferences. Using panel data on the choices of single women with children from the National Longitudinal Surveys (NLSY) 1979, we provide estimates of the degree of time‐inconsistency, and of its influence on the welfare take‐up decision. With these estimates, we conduct counterfactual experiments to quantify a measure of the utility loss stemming from the inability to commit to future decisions, and the potential gains from commitment mechanisms such as welfare time limits and work requirements.     

THE INTERGENERATIONAL CORRELATION BETWEEN CHILDREN'S ADULT EARNINGS AND THEIR PARENTS' INCOME: RESULTS FROM THE MICHIGAN PANEL SURVEY OF INCOME DYNAMICS

Intergenerational correlations between parental income and child earnings reflect the extent of intergenerational economic mobility and equality of opportunity. Previous estimates are about 0.2, but these estimates suffer from a number of problems, including the use of but one year of observations and of nonrandom samples. We present new estimates based on the Panel Study of Income Dynamics. These estimates suggest correlations over 0.5 with longer-run income and earning measures, as well as some gender and race differences and some impact of liquidity constraints. They also suggest that the intergenerational elasticity is greater as parental income increases, the opposite of the Becker-Tomes conjecture.     

ADULT EDUCATION AND EARNINGS: EVIDENCE FROM BRITAIN

This paper uses the National Child Development Study to investigate the relationship between adult schooling and labour market earnings for men. In line with several other studies, the findings suggest that there are returns to all educational qualifications acquired early in life. A variety of statistical models are estimated to try to measure the causal effect of adult education on earnings. Careful analysis reveals that there are no genuine returns to additional qualifications awarded in middle adulthood. The central conclusion of this paper is that rates of return to human capital are greater for individuals who were educated early in life.     

POVERTY DYNAMICS DURING TRADE REFORM: EVIDENCE FROM RURAL VIETNAM

This paper implements and adapts the conceptual framework developed by Winters (2002) that identifies the transmission mechanisms between trade policy reform and household welfare outcomes. We make use of household panel data from Vietnam collected in two years, 1992–93 and 1997–98 that span the very earliest years of the reform period and its immediate after effects. Poverty dynamics are modeled using changes in consumption expenditure and poverty transition models. The trade effect is captured by a set of variables that are most likely to have an impact on rural poverty, namely prices of staples and employment in the export sector. We show that trade liberalization has a material and positive effect on rural household welfare and this trade effect is largely transmitted to the poor through the labor market channel.

INCOME TAXES AND THE COMPOSITION OF PAY: EVIDENCE FROM THE BRITISH HOUSEHOLD PANEL SURVEY

According to the standard principal‐agent model, the optimal composition of pay should balance the provision of incentives with the individual demand for insurance. Do income taxes alter this balance? We show that the relative share of Performance‐related pay (PRP), on total pay is reduced by higher average and marginal income taxes. Empirical evidence based on the British Household Panel Survey is consistent with the theoretical predictions of the tax–augmented principal‐agent model. Our estimates suggest that a 10% reduction in the marginal income tax rate, holding the average tax rate constant, increases the share of PRP in total pay by 2.25–3.02%, depending on the empirical specification. Similarly, a 10% reduction in the average income tax rate, holding the marginal tax rate constant, increases the share of PRP in total pay by 5.10–5.27%.     

DEMOCRACY AND ECONOMIC REFORM: THEORY AND SOME EVIDENCE FROM THE RUSSIAN CASE

The paper examines theoretical issues concerning the relationship between political democracy and economic reform and builds on the empirical material from the recent experience of Russia. The process of transition to democracy is shown to have started spontaneously due to the situation of power stalemate among pressure groups that came to control the communist system in the years preceding its ultimate collapse. The unrestrained control by those groups is shown to be the reason behind the continued economic collapse, while gradual build-up of the democratic system can in the long run act in the direction of improving the chances for a successful economic reform.     

PRICE,PRODUCT QUALITY,AND EXPORTER DYNAMICS: EVIDENCE FROM CHINA

This article develops a model of heterogeneous firms that endogenously choose prices and product quality to build demand in export markets. New exporters optimally charge relatively low prices and produce low‐quality goods upon entry. Product quality, prices, and sales increase as demand grows. We structurally estimate model parameters using Chinese customs data. The estimated incentive to build future demand reduces average export prices by 0.7% and increases export sales by 4% upon entry. Endogenous demand accumulation causes estimated export prices, product quality, and sales to grow by 2.2%, 12%, and 79%, respectively, over the following five years.     

TEACHER LOCATION CHOICE AND THE DISTRIBUTION OF QUALITY: EVIDENCE FROM NEW YORK CITY

This article studies the distribution of teacher quality measures across the New York City school system. Because teachers are paid along a fixed salary schedule and they have the option to transfer schools, this analysis measures the degree to which environmental factors affect teacher location choice. Both school-based and neighborhood-based effects are measured, and both types are significant. Furthermore, this article finds that the location of the school in relation to the suburban borders is an important determinant of teacher location choice. (JEL I29 , J24 , J61 )     

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.     

A PATHWAY TO HOMEOWNERSHIP? EVIDENCE FROM THE IMMIGRATION REFORM AND CONTROL ACT OF 1986

The impact of legal status on economic outcomes has been well documented in the literature with most research focused on labor market outcomes such as wages and occupational mobility. In this paper, I utilize the exogenous variation created the Immigration Reform and Control Act (IRCA) of 1986 to estimate the effect of amnesty polices on homeownership among undocumented immigrants. Using a regression discontinuity framework, the results suggest that the IRCA increased homeownership rates of eligible immigrants by around 4 percentage points relative to ineligible immigrants. Moreover, an extension to the main analysis suggests that immigrants ineligible for the IRCA adjusted their household formation by increasing the rates of coresidency. (JEL J61, R23, R31)     

PUBLIC INVESTMENT,TAX EVASION,AND THE WELFARE EFFECTS OF A TARIFF REFORM

Contrary to the case considered in literature, the experience of developing countries indicates that the tariff reforms have not been revenue neutral due to the heavy dependence of developing countries on trade taxes and pervasive tax evasion. In contrast to the plausibility of a welfare loss shown by the current literature, when the adverse effect of the loss of tariff revenue on public investment is factored in, the welfare outcome of the tariff reforms of past few decades turns out to be much more pessimistic. The constraints imposed by tariff dependence and tax evasion imply that future tariff reforms in these countries should be undertaken after strengthening their domestic tax system and augmenting the ability of their governments to fight tax evasion. For countries of sub‐Saharan Africa, where such reforms are likely to be concentrated, this would need planning and capacity building over a longer time horizon. (JEL D61, D62, F13, H26)     

GLOBAL AND DISAGGREGATED MEASURES OF EARNINGS MOBILITY: EVIDENCE FROM FIVE EUROPEAN COUNTRIES

This paper offers the first application of the local approximation method pioneered by Schluter and Trede (2003) for the Shorrocks mobility indices across the earnings distribution for a range of European Countries covering the main European social models: Denmark, Germany, Spain, the UK and Italy in the pre‐accession EU (1994‐2001). This insightful approach allows us to offer a global and disaggregate analysis of mobility as proportionate change in inequality and hence provide the reader with a full set of information to make his/her own judgment about the extent of mobility and country ranking. Specifically, we investigate the degree to which mobility is driven by low or high earners and how this picture changes across three different earnings measures: full‐time full‐year working, adding part‐time working and then part‐year working. Our results draw out some general key facts. First of all the vast bulk of the measured mobility occurs in the tails especially the lower tail with at least half of the index driven by mobility in the bottom earning quintile. Second, in the top 20 percent of the distribution there are few movements of earnings that effect the level of permanent inequality except in Denmark. Third, no country has a clear dominance for mobility across the full earnings distribution but Denmark differs from the other countries with clearly greater mobility in the middle and at the top. Finally, we find that with the exception of Denmark and Italy, mobility does not lead to clear convergence to the mean but rather to points around 0.7‐0.8 and 1.5 to 2 times the mean.     

ESTIMATING THE INCIDENCES OF THE RECENT PENSION REFORM IN CHINA: EVIDENCE FROM 100,000 MANUFACTURERS

An ongoing reform in China mandates employers to contribute significant amounts to employee pension funds. The current study estimates the impact of this reform on the wage, employment, and performance of firms using data from over 140,000 medium and large manufacturers in China during 2004 and 2006. We find that the nominal wages of employees were rigid, but their real wages may have declined due to the pension reform. In addition, we find an interesting dichotomy in the incidences of pension reform. In localities with high agglomeration levels, firms' profits declined because the pension burden could not be fully transferred to employees. In less agglomerated jurisdictions, firms responded positively to pension reform, possibly because local governments over‐subsidized the pension costs as a way to attract investment.

PERSONALITY TRAITS AND THE PERCEPTION OF MACROECONOMIC INDICATORS: SURVEY EVIDENCE

I examine the determinants of both perceived inflation and unemployment in one single survey and include Big Five traits in the analysis. This is the first survey on this topic in Germany. My sample consists of 1771 students from different fields and levels. Using PhD students’ estimates as a reference, I create categories for underestimation and overestimation of both variables. Multinomial logit regressions show that females overestimate both variables. Education and news consumption reduce misestimation. A higher level of Neuroticism is related with a higher probability to overestimate unemployment. Overstating (understating) one indicator is associated with overstating (understating) the other.     

FISCAL POLICY AND AGGREGATE CONSUMPTION: NEW EVIDENCE FROM THE UNITED STATES

In this paper we estimate the marginal rate of substitution between aggregate per-capita consumption and per-capita government expenditure on goods and services using US quarterly data over the period 1953 to 1993. This estimate is an important input to any attempt to assess the overall effectiveness of fiscal policy since it directly affects the size of the fiscal policy multiplier. Other recent consumption studies which incorporate the effects of government expenditure have failed to establish a stable estimate of the marginal rate of substitution. We argue that this failure results from imposing the unrealistic assumption that this parameter is constant. In contrast, we allow the marginal rate of substitution to depend on both the level and composition of government spending.     

PREFERENCES FOR STATE TAX AND SPENDING POLICIES: EVIDENCE FROM SURVEY DATA ON THE ROLE OF INCOME

Employing a commonly-used method of creating a continuous income variable from categorical data, we obtain results from a fiscal survey that reveal a strong nonmonotonic effect of income on the willingness to pay additional taxes for state expenditures on education and public aid. The existence of income-demand schedules that are U- or inverted U-shaped casts doubt on the appropriateness of assuming that the median income voter is decisive. After investigating the sensitivity of our results to different income measures, we suggest that fiscal surveys should be designed to provide sufficiently detailed information about respondents'incomes, especially for high-income respondents.
