Premium Subsidies and Social Insurance: Substitutes or Complements?

Premium subsidies have been advocated as an alternative to social health insurance. These subsidies are paid if expenditure on health insurance exceeds a given share of income. In this paper, we examine whether this approach is superior to social insurance from a welfare perspective. We show that the results crucially depend on the correlation of health and productivity. For a positive correlation, we find that combining premium subsidies with social insurance is the optimal policy.social insurance, health insurance, redistributive taxation, equity

Transfers within a three generations family: when the rotten kids turn into altruistic parents

We study exchanges between three overlapping generations with non-dynastic altruism. The middleaged choose informal care provided to their parents and education expenditures for their children. The young enjoy their education, while the old may leave a bequest to their children. Within each period the three generations play a “game” inspired by Becker’s (1974, 1991) rotten kids framework, with the added features that the rotten kids turn into the altruistic parent in the next period and that parents invest in the education of their children. We show that Becker’s rotten kids theorem holds for the single period game in that informal aid is set according to an efficient rule. However, education is distorted upwards. In the stationary equilibrium the levels of both transfers are inefficient: education is too large and informal aid is too low

Rotten spouses, family transfers and public goods

We show that once interfamily exchanges are considered, Becker?s rotten kids mechan- ism has some remarkable implications that have gone hitherto unnoticed. Specifically, we establish that Cornes and Silva's (1999) result of e¢fficiency in the contribution game amongst siblings extends to a setting where the contributors (spouses) belong to different families. More strikingly still, the mechanism does not just have consequences for efficiency but it may have dramatic redistributive implications. In particular, we show that the rotten kids mechanism combined with a contribution game to a house- hold public good may lead to an astonishing equalization of consumptions between the spouses and their parents, even when their parents'wealth levels differ. We consider two families, each consisting of a parent and an adult child, who are "linked"by the young spouses. Children contribute part of their time to a household (couple) public good and provide attention to their respective parents"in exchange"for a bequest. Spouses behave towards their respective parents like Becker's rotten kids; they are purely selfish and anticipate that their altruistic parents will leave them a bequest. The most striking results obtain when wages are equal and when parents'initial wealth levels are not too di¤erent. For very large wealth differences the mechanism must be supplemented by a (mandatory) transfer that brings them back into the relevant range. When wages differ but are similar the outcome will be near efficient (and near egalitarian)

Long-term care policy, myopia and redistribution

This paper examines whether myopia (misperception of the long-term care (LTC) risk) and private insurance market loading costs can justify social LTC insurance and/or the subsidization of private insurance. We use a two-period model wherein individuals differ in three unobservable characteristics: level of productivity, survival probability and degree of ignorance concerning the risk of LTC (the former two being perfectly positively correlated). The decentralization of a first-best allocation requires that LTC insurance premiums of the myopic agents are subsidized (at a "Pigouvian" rate) and/or that there is public provision of the appropriate level of LTC. The support for the considered LTC policy instruments is less strong in a second-best setting. When social LTC provision is restricted to zero, a myopic agent's tax on private LTC insurance premiums involves a tradeoff between paternalistic and redistributive (incentive) considerations and we may have a tax as well as a subsidy on private LTC insurance. Interestingly, savings (which goes untaxed in the first-best but plays the role of self-insurance in the second-best) is also subject to (positive or negative) taxation. Social LTC provision is never second-best optimal when private insurance markets are fair (irrespective of the degree of the proportion of myopic individuals and their degree of misperception). At the other extreme, when the loading factor in the private sector is sufficiently high, private coverage is completely crowded out by public provision. For intermediate levels of the loading factors, the solution relies on both types of insurance

Long-term care and lazy rotten kids

This paper studies the determination of informal long-term care (family aid) to dependent elderly in a worst case scenario concerning the "harmony" of family relations. Children are purely selfish, and neither side can make credible commitments (which rules out e¢ cient bargaining). The model is based on Becker's "rotten kid" specification except that it explicitly accounts for the sequence of decisions. In Becker's world, with a single good, this setting yields efficiency. We show that when family aid (and long-term care services in general) are introduced the outcome is likely to be inefficient. Still, the rotten kid mechanism is at work and ensures that a positive level of aid is provided as long as the bequest motive is operative. We identify the inefficiencies by comparing the laissez-faire (subgame perfect) equilibrium to the first-best allocation. We initially assume that families are identical ex ante. However, the case where dynasties differ in wealth is also considered. We study how the provision of long-term care (LTC) can be improved by public policies under various informational assumptions. Interestingly, crowding out of private aid by public LTC is not a problem in this setting. With an operative bequest motive, public LTC will have no impact on private aid. More amazingly still, when the bequest motive is (initially) not operative, public insurance may even enhance the provision of informal aid

The Political Sustainability of Germany's Environmental Tax Rate

We analyze the German ecotax package in a model of overlapping generations and majority voting. The package consists of the ecotax rate and the budgetary rule which assigns a fraction of the tax revenue to the reduction of pension contributions while holding pension benefits constant. The old and the young generation have different preferences with respect to the tax rate and the use of the tax revenue. Our theoretical model as well as the calibration of our model show that the median voter s preferred tax rate may well exceed the efficient tax rate whenever his income is sufficiently high. This is the likelier the more CO2 is degraded and removed from the atmosphere. Furthermore, the median voter prefers earmarking of tax revenue to reductions in pension contributions. The latter is quite an accurate prediction of the situation in Germany where the share of tax revenue devoted to the pension scheme amounts to more than 90%

Income taxation of couples, spouses' labor supplies and the gender wage gap

We study the taxation of couples when female wages do not re?ect their true productivity. We show that the expression for the marginal tax rates of the male spouses is the same as in a Mirrleesian world where wages re?ect true productivities. Marginal taxes for the female spouses are reduced because of a Pigouvian correction. Consequently, the wage discrimination pleads for a lower marginal tax on the female spouse. Furthermore, the distortion of a couples?tradeo¤ between male and female labor supply is the same as in a Mirrleesian world without a gender wage gap. It only depends on true productivities and not on wages. In other words, the tax system completely neutralizes the extra distortion introduced by the wedge between the female spouse?s wage and her true productivity
