Transferable Ageing Provisions in Individual Health Insurance Contracts

Abstract. We consider lifetime health insurance contracts in which ageing provisions are used to smooth the premium profile. The capital stock accumulated for each individual can be decomposed into two parts: a premium insurance and an annuitized life insurance, only the latter being transferable between insurers without triggering premium changes through risk segmentation. In a simulation based on German data, the transferable share declines in age and falls with an increasing age of entry into the contract. In spite of different benefit profiles, it is almost identical for women and men.     

Direct evidence of risk aversion as a source of advantageous selection in health insurance

Using the self-stated degree of risk aversion regarding health from the GSOEP we find some evidence for risk aversion being a source of advantageous selection. Risk averse men more often procure supplementary insurance for hospital visits despite needing the additional coverage less.     

Education cost, intergenerational mobility, and income inequality

Using a modified version of the Maoz and Moav [Maoz, Y. D. and Moav, O., 1999. Intergenerational mobility and the process of development. Economic Journal 109(458) 677-697] model, we show that the dynamics of income inequality and intergenerational mobility, and the effects of technological changes on inequality, depend crucially on the share of education cost in income.     

When prices hardly matter: Incomplete insurance contracts and markets for repair goods

This paper looks at markets characterized by the fact that the demand side is insured. In these markets, a consumer purchases a good to compensate consequences of unfavorable events, such as an accident or an illness. Insurance policies in most lines of insurance base indemnity on the insured's actual expenses, i.e., the insured would be partially or completely reimbursed when purchasing certain goods. In this setting, we discuss the interaction between insurance and repair markets by focusing, on one hand, upon the development of prices and the structure of markets with insured consumers, and, on the other hand, the resulting backlash on optimal insurance contracting. We show that even in the absence of ex post moral hazard the extension of insurance coverage will lead to an increase in prices as well as to a socially undesirable increase in the number of repair service suppliers if repair markets are imperfect.     

The effect of education subsidies on regional economic growth and disparities in China

This paper examines the impact of education subsidies on regional economic growth and the disparities between two Chinese regions, Jiangsu and Liaoning, by simulating their economies in a six-period overlapping generations model in which individuals decide their length of education. This study estimates the long-run growth rates, that is, the steady growth paths of the regional economies based on current education subsidies, and explores their effect on human capital accumulation, namely in terms of economic growth while considering the increase in education subsidies. Because greater government subsidies in education induce individuals to invest in human capital, both regions achieve higher economic growth. Moreover, because of the large differences in productivity between the regions, the growth gap widens with evenly raised education subsidy rates.     

Voting over income taxation

A major problem of the positive theory of income taxation is to explain why statutory income tax schedules in practice are marginal-rate progressive. While it is commonly believed that this is but a simple consequence of the fact that the number of relatively poor voters exceeds that of richer voters in general, putting this contention in a voting equilibrium context is not a trivial task. We do this here in the context of nonlinear taxation and attempt to provide a formal argument in support of this heuristic claim. We first establish the existence of mixed strategy equilibria and identify certain cases in which marginal-rate progressive taxes are chosen almost surely by the political parties. Unfortunately, we also find that if the tax policy space is not artificially constrained, the support of at least one equilibrium cannot be contained within the set of marginal-rate progressive taxes.     

Credit constraint and human capital investment: an empirical analysis using Brazilian household budget survey

This article is a first step towards understanding the relationship between credit market imperfections and inequality of opportunity in skill formation. The main goal is to investigate the effects of the credit constraint on the optimal human capital decision, in terms of degree of schooling, taking into account the household preferences for education. Our starting point is a theoretical model of human capital investment decision with credit constraint. Following a previous model in the literature, we propose a reduced-form approach that estimates the relation between education decision and initial wealth in Brazil. Our empirical analysis is conducted using data from a Brazilian Household Budget Survey (Pesquisa de Orçamentos Familiares), for years 2002–2003 and 2008–2009. Our results point out that education decision is in fact credit constrained. The empirical results show a strong and highly significant effect of wealth on educational level of children, teenagers and adults, even controlling by education expenditures. But we find no evidence of credit constraint on high level education decision, like undergraduate and graduate levels.     

Voting by committees under constraints

We consider social choice problems where a society must choose a subset from a set of objects. Specifically, we characterize the families of strategy-proof voting procedures when not all possible subsets of objects are feasible, and voters’ preferences are separable or additively representable.     

Why is child labor illegal?

We present a theory of the emergence of laws restricting child labor or imposing mandatory education that is consistent with the fact that poor parents tend to oppose such laws. We find that if altruistic parents are unable to commit to educating their children, child-labor laws can increase the welfare of higher-income parents in an ex ante sense. On the basis of an empirical analysis of Latin-American household surveys, we demonstrate that per capita income in the country of residence has the predicted effect on child labor supply, even after controlling for other household characteristics.     

The political economy of public education

I study the relationship between income inequality and public spending in education in a voting model. Voters collectively choose the uniform quality level of public education, the amount of a public good, and the tax rate on labor income. Parents can decide to opt-out of the public education system by purchasing private education at the desired quality level, and children’s expected income is assumed to be increasing in the quality of education. I show that higher income inequality is associated with higher governmental spending in education if and only if the expected marginal returns to education are larger for the children of relatively low income parents. In turn, better public education tends to reduce future inequality. These results are consistent with most findings in the empirical literature about public investment in education. Lastly, I show that for other kind of publicly provided goods, such as health care, the relationship with income inequality exhibits an ambiguous or opposite sign.     

Post‐secondary attendance by parental income in the U.S. and Canada: Do financial aid policies explain the differences?

We examine the extent to which tuition and needs‐based aid policies explain important differences in the relationship between family income and post‐secondary attendance relationships between Canada and the U.S. Using data from recent cohorts, we estimate substantially smaller attendance gaps by parental income in Canada relative to the U.S., even after controlling for family background, cognitive achievement, and local‐residence fixed effects. We next document that U.S. public tuition and financial aid policies are actually more generous to low‐income youth than are Canadian policies. Equalizing these policies across Canada and the U.S. would likely lead to a greater difference in income‐attendance gradients.     

Modeling life expectancy in Turkey

This study is concerned with understanding the factors of life expectancy in Turkey for the period 1965-2005. The determinants of life expectancy in Turkey are related to selected social, economical and environmental factors. Bounds testing approach to cointegration is employed to compute the long-run elasticities of longevity with respect to the selected economic, social and environmental factors. There exists no previous study that estimates empirically the determinants of life expectancy in Turkey on the basis of time series data and cointegration framework. Empirical results suggest that nutrition and food availability along with health expenditures are the main positive factors for improving longevity whereas smoking seems to be the main cause for mortality. The results also draw a number of policy recommendations for improving longevity.     

An experimental evaluation of a proactive pastoral care initiative within an introductory university course

Improving student retention and academic performance is a key objective for higher education institutions, and finding effective interventions for assisting with at-risk students is therefore important. In this article, we evaluate a proactive pastoral care intervention that was trialled in an introductory economics course in New Zealand. We first identified students at high risk of failure, and then randomized these students into two treatment groups and a control group. The first treatment group received an email with information about academic support, while the second treatment group received the email as well as a personal telephone call to follow-up. In evaluating the impact of the intervention trial, we found that the first intervention did not significantly improve student outcomes, but the second intervention improved outcomes in one of the two semesters evaluated. Overall, the initiative was a qualified success. It is both simple and cost-effective and should be considered for wider implementation and further evaluation.     

Voting for Redistribution under Desert‐Sensitive Altruism*

We endow individuals who differ in skills and tastes for working, with altruistic preferences for redistribution in a voting model where a unidimensional redistributive parameter is chosen by majority voting in a direct democracy. When altruistic preferences are desert‐sensitive (i.e., when there is a reluctance to redistribute from the hard‐working to the lazy), we show that lower levels of redistribution emerge in political equilibrium. We provide empirical evidence that preferences for redistribution are not purely selfish, and that desert‐sensitive motivations play a significant role. We estimate that preferences for redistribution are significantly more desert‐sensitive in the US than in Europe.     

Hit and (they will) run: The impact of terrorism on migration

We analyze the influence of terrorism on migration for 152 countries during 1976-2000. We find robust evidence that terrorism is among the ‘push factors’ of skilled migration, whereas it is not robustly associated with average migration.     

Voting blocs, party discipline and party formation

I study the strategic incentives to coordinate votes in an assembly. Coalitions form voting blocs, acting as single players and affecting the policy outcome. In an assembly with two exogenous parties I show how the incentives to accept party discipline depend on the types of the agents, the sizes of the parties, and the rules the blocs use to aggregate preferences. In a game of fully endogenous party formation, I find sufficient conditions for the existence of equilibria with one bloc, two blocs, and multiple blocs.     

Effects of rotation scheme on fishing behaviour with price discrimination and limited durability: Theory and evidence

This paper examines how rotation arrangement between two groups of fishers with different institutional arrangements affects fishing behaviour and economic outcomes in a particular economic environment characterised by price discrimination and product durability. In one group, fishers cooperate and maximise the extraction of rents, while members in the second group behave non-cooperatively. Applying a model of alternating duopoly, we show that the cooperating group behaves like a price discriminating monopolist and tends to uphold prices. When the two groups rotate fishing days the cooperating group tends to produce more, which prevents the non-cooperating group from unprofitable demand preemption.     

Household survey data for research on well-being and behavior in Central Asia

This paper summarizes the micro-level survey evidence from Central Asia generated and analyzed in the period 1991–2012. We provide an exhaustive overview over all accessible individual and household-level surveys undertaken in Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan – and of all academic papers published using these datasets. We argue that Central Asia is a fascinating region for the study of comparative economics given its dual experience of transition and development. However, the region is also understudied, in part due to lack of data, and especially due to a lack of panel data. We identify knowledge gaps derived from this lack of longitudinal surveys and suggest worthwhile areas for future research. Finally, we also present a new and novel individual-level panel dataset called “Life in Kyrgyzstan”.     

Differences by mother’s education in the effect of childcare on child obesity

Previous studies have found adverse effects of maternal employment on child obesity for higher educated mothers. Using a quasi-structural model, we find additionally a lower risk of obesity for children of less educated mothers with increased time in non-parental childcare.
