Social Interaction Effects in Disability Pension Participation: Evidence from Plant Downsizing*

We estimate the magnitude of social interaction effects in disability pension participation among older workers in Norway. The problem of omitted variable bias is addressed using the exposure of an individual's neighbors to plant‐downsizing events as an instrument for the disability entry rate among the individual's previously employed neighbors. Our instrumental variable (IV) estimates suggest that an increase of one percentage point in the participation rate of previously employed neighbors increased the subsequent four‐year entry rate of older workers by about 0.4 percentage points. Numerous robustness and specification tests appear to support the validity of the identifying assumption in our IV strategy.     

The redistributive effects of political reservation for minorities: Evidence from India

We examine the impact of political reservation for disadvantaged minority groups on poverty. To address the concern that political reservation is endogenous, we take advantage of the state-time variation in reservation in state legislative assemblies in India generated by national policies that cause reservations to be revised and the time lags with which revised reservations are implemented. Using data on sixteen major Indian states for the period 1960-2000, we find that increasing the share of seats reserved for Scheduled Tribes significantly reduces poverty while increasing the share of seats reserved for Scheduled Castes has no impact on poverty. Political reservation for Scheduled Tribes has a greater effect on rural poverty than urban poverty, and appears to benefit people near the poverty line as well as those far below it.     

Mother's education and child development: Evidence from the compulsory school reform in China

This paper investigates the causal impact of mother's schooling on various outcomes of adolescent development by exploiting the temporal and geographical variations in the enforcement of compulsory schooling laws in China. Using data from China Family Panel Studies, we find that mother's education increases adolescents’ school enrollment, math test scores, college aspiration, and internal locus of control related to education. Mother's education also improves adolescent mental health status and reduces the incidence of underweight. We also find considerable gender heterogeneity in the effects of mother's education. The results further indicate that mother's education leads to an increase in family resources for children and an improvement in maternal mental health and parenting, which we interpret as potential mechanisms behind our findings.     

The Indian Public Distribution System as provider of food security: Evidence from child nutrition in Andhra Pradesh

We study whether a sudden increase of the price of rice supplied by the Indian Public Distribution System in Andhra Pradesh, a large Indian state, had a negative impact on child nutrition. A few months after the price increase, a health survey started to record weight for a large sample of children. The data collection continued for several months, so that children measured later lived for a longer period of time in a less favorable price regime. Using different estimation techniques we find that longer exposure to high prices are not accompanied by worse nutritional status, as measured by weight-for-age.     

OECD pension reform: The role of demographic trends and the business cycle

Using a new real-time dataset from Beetsma et al. (2020) containing all pension reform measures in 23 OECD countries between 1970 and 2017, we demonstrate that, in contrast to what one might a priori expect, the timing of pension reform measures coincides with business cycle shocks and not with current or projected demographic shocks. The OECD-wide demography only explains the general reform trend. We rationalize this finding using a political-economy model with two-sided adjustment costs to explain a lack of response of pension reform measures to changes in demographic indicators.     

The impacts of social pension on rural household expenditure: evidence from China

In 2009, China began to implement a new social pension scheme in rural areas. We examine the impacts of this social pension on two main components of rural household expenditure, consumption and agricultural production investment. Our findings show that on average, rural households increase consumption by 1–3% and agricultural investment by as high as 6–9% in pilot counties. Further estimations reveal that the pension mainly affects the households with old-aged members and the poorer families, and that the saving rate hasn’t been changed by the pension, which support more the contingent income than the life-cycle hypothesis. We also find that among various types of expenditures, the most dramatic increases have occurred in food consumption and operational inputs on agricultural production.     

The human capital consequences of civil war: Evidence from Guatemala

We combine data from the 2002 National Population Census and the distribution of the number of human rights violations and victims across 22 departments to examine how Guatemala's 36-year-long civil war affected human capital accumulation. The year of birth and the department of birth jointly determine an individual's exposure during school age to three different periods of the civil war, namely the initial period (1960-1978), the worst period (1979-1984), and the final period (1985-1996). We find a strong negative impact of the civil war on the education of the two most disadvantaged groups, namely rural Mayan males and females. Among rural Mayan males, those who were school age during the three periods of the civil war in departments where more human rights violations were committed completed 0.27, 0.71, and 1.09 years less of schooling respectively whereas rural Mayan females exposed to the three periods of the war completed 0.12, 0.47, and 1.17 years less of schooling respectively. Given an average of 4.66 and 3.83 years of schooling for males and females, these represent declines of 6, 15, and 23% for males and 3, 12, and 30% for females. Our results are robust to the inclusion of indicators for department of residence, year of birth, and controls for different trends in education and human development in war-affected and peaceful departments of Guatemala and suggest that the country's civil war may have deepened gender, regional, sectoral, and ethnic disparities in schooling.     

Gender difference in the impact of retirement on cognitive abilities: Evidence from urban China

This paper examines the impact of retirement on cognitive functioning by gender in urban China and investigates the underlying mechanisms. Based on data from the China Health and Retirement Longitudinal Study, the paper uses the mandatory retirement ages and different policy enforcement between the public and private sectors as instruments for retirement status. The analysis finds substantial gender heterogeneity in the effect of retirement on cognition, with a positive and significant effect for males, but a negative and less significant effect for females. The beneficial effects on cognition are stronger for male blue-collar workers, who are likely to pursue a more active lifestyle at retirement. Further investigation shows that the results are partly driven by differential behavioral changes at retirement, and the gender difference in retirement ages may also play a potential role.     

The cost of imperfect agency in health care: Evidence from rural Cameroun

Health is a pressing problem facing Africans today, yet health care systems in Africa are inadequate and under-funded. We show that pervasive imperfect agency means that they are also inefficient. Imperfect agency (due to unobservable medical effort) is a recognized market failure in health care, but its impact is difficult to measure. We take an indirect approach to estimation and infer the cost of unobservable effort from the behavior of utility-maximizing patients, specifically their willingness to incur measurable costs to avoid practitioners who shirk. We use a unique data set from rural Cameroun where patients choose between the government health system, church-operated (mission) health facilities and, importantly, traditional healers. Traditional healers provide health services on an outcome–contingent basis where patients pay only if they are cured. Both government and mission facilities, in contrast, are paid on a fee-for-service basis. Patients' choices of practitioners, combined with quantitative information about patients' illnesses, permit a structural estimation of the value of unobservable medical effort. The results allow investigation into the nature of agency, its costs, and the manner in which contracts reduce and patient behavior mitigates those costs. We estimate that in the absence of imperfect agency, utility from health care would increase by at least 160%. Even in the face of imperfect agency, the sophistication of patients in choosing between existing contracts for different illnesses increases utility by up to 20%.

The Effect of Marriage on Education of Immigrants: Evidence from a Policy Reform Restricting Marriage Migration*

We investigate the effect of immigrants’ marriage behavior on dropout from education. To identify the causal effect, we exploit a recent Danish policy reform that generated exogenous variation in marriage behavior by a complete abolishment of marriage migration for immigrants below 24 years. The reform influenced immigrants from countries with a high historical rate of marriage migration more than immigrants from country groups with a low rate. We find that the dropout rate for males increases by 25 percentage points as a consequence of marriage to a marriage migrant, whereas the effect for females is small and mostly insignificant.     

The Dynamics of Poverty and the Promotion of Transition from Non‐Regular to Regular Employment in Japan: Economic Effects of Minimum Wage Revision and Job Training Support

Comparison between Japan and other advanced countries shows that the relative poverty rate is high in Japan, and that many of the poor households are those with a non‐regular worker. As for mobility between income classes, the proportion of households remaining in the poor class for a long period of time in Japan is close to the average for EU countries. The panel estimation of its effect on wages shows that the raising of the minimum wage is statistically significantly associated with an increase in wages of non‐regular workers, in particular, female, but does not seem to decrease employment. The result shows that for male non‐regular workers, firm‐provided training promotes their transition to regular employment, and that for female non‐regular workers, occupational training promotes their transition to regular employment at different firms.     

The determinants of China's lending rates and interest rates pass-through: A cointegration analysis

Based on quarterly data between Q4, 2008–Q4, 2017, this study examines the interest rates pass-through from policy rate to lending rates, and more broadly, the determinants of lending rates in China. The results show that while there is a certain level of pass-through from money market rates to lending rates, and the interest rates pass-through has improved after the interest rate liberalization completion on October 2015, this pass-through is also negatively affected by the asset quality of commercial banks and shadow banking activities as well. This study also finds that the macroeconomic condition also affects the lending rates.     

Timing and duration of paternal migration and the educational attainment of left‐behind children: Evidence from rural China

This paper examines the relationship between the migration of men from rural China and the educational attainment of their left‐behind children. The importance of migratory timing and duration are addressed. Using survey data, the study found that compared with rural children of nonmigrant parents, rural children of migrant fathers have a lower probability of being enrolled in school. In addition, the relationship between migratory timing, duration, and school enrollment shows an interesting pattern; children whose fathers migrated when they were infants are more likely to be enrolled in school, but children whose fathers migrated before their birth or after they reached school age are less likely to be enrolled in school. Possible explanations for this pattern are provided.     

Incomes and Inequality in the Long Run: The Case of German Elderly

Abstract. We use German Sample Survey income data to examine the income distribution for elderly individuals during the period from 1978 to 2003. The elderly population, defined as people of age 55 and older, is decomposed by people resident in the Old and New Federal States. Further, we distinguish between persons receiving old‐age pensions and persons who do not. Inequality estimates are decomposed by income components, and the bootstrap method is used to test for statistical significance of results.
