Birth-date dependent population ethics: critical-level principles

"This paper investigates birth-date dependent principles for social evaluation in an intertemporal framework in which population size may vary. We weaken the strong Pareto principle in order to allow individuals' birth dates to matter in establishing a social ordering. Using the axiom independence of the utilities of the dead, we characterize population principles with a recursive structure. If the individual substitution principle and an individual intertemporal equivalence axiom are added, birth-date dependent generalizations of the critical-level generalized utilitarian principles result. Stationarity leads to the special case of geometric discounting."     

Optimal Utilitarian Taxation and Horizontal Equity

We impose a horizontal equity restriction on the problem of finding the optimal utilitarian tax mix. The horizontal equity constraint requires that individuals with the same ability have to pay the same amount of taxes regardless of their preferences for leisure. Contrary to normal findings, we find that a good that is complementary to leisure can be encouraged by the tax system and that a good that normally should be discouraged by the tax system can be subsidized even if the economy is composed of only two private commodities plus leisure. Also, the marginal effective tax rate can be different from zero at the top of the ability distribution when the tax mix obeys the horizontal equity constraint.     

The effect of the timing and spacing of births on the level of labor market involvement of married women

We analyze the effect of the timing and spacing of births on the labor supply of married women in a framework that accounts for the endogeneity of the labor market and fertility decisions, for the heterogeneity of the effects of children on labor supply and their correlation with the fertility decisions, and for the correlation of sequential labor market decisions. Delaying the first birth leads to higher pre-natal levels of labor market involvement and reduces the negative effect of the first child on labor supply. The effect of the second child increases with the spacing of the two births as women, returning to work after the first birth, finance child care time increasingly through reductions in market time. Individual heterogeneity is considerable; women with lower propensity for children have the first birth later in life and space subsequent births more closely together, work more before the birth of the first child, but face larger effects of children on their labor supply.     

Forecasting first births

This study is concerned with one aspect of the family cycle, namely, the transition from young married to young married with small children. The focus is on developing models to forecast entries into this latter stage for the purpose of marketing research. "Using ordinary least squares, forecasting models were estimated for (1) total number of first births, (2) number of white first births, and (3) number of nonwhite first births." Models are estimated for both the United States and California using data from official sources.     

Utilitarian mechanism design for an excludable public good

This paper studies the design of optimal utilitarian mechanisms for an excludable public good. Excludability provides a basis for making people pay for admissions; the payments can be used for redistribution and/or funding. Whereas previous work assumed that admissions are governed by the payment or nonpayment of a price, this paper allows for arbitrary admission rules. With sufficient inequality aversion, nondegenerate randomization in admissions is shown to be desirable for certain model specifications, with and without participation constraints. The paper also gives a sufficient condition on the distribution of preferences under which randomization is undesirable.     

Efficient Management of Product Durability and Recyclability under Utilitarian and Chichilnisky Preferences

In a dynamic general equilibrium vintage model we explicitly consider the relationship between the product attributes durability and recyclability. Efficient management in the case that green design markets fail is analyzed both under Utilitarian and Chichilnisky preferences. It turns out (a) that durability may be inefficient even in a perfectly competitive economy in which environmental externalities are absent, (b) that the efficiency-restoring tax-subsidy schemes crucially depend on the kind of preferences, and (c) that changing the property rights for consumption goods and residuals is a promising policy option to overcome market failure independent of the kind of preferences.     

Transnational Land Deals and Gender Equality: Utilitarian and Human Rights Approaches

Transnational land deals pose vexing normative (ethical) questions, not least concerning gendered participation and outcomes. This article explores utilitarian and human rights approaches to gender equality in selected policy initiatives on the land deals. While global policy literature manifests growing attention to women in agriculture, the review found the analysis of gender in early policy initiatives to be absent or weak. Utilitarian arguments were used to justify deals but rarely presented women's participation as a means of social progress or so-called smart economics. Human rights documents were more likely to be critical of the deals and to mention gender, though with little elaboration. While to some extent amended by the emphasis on gender equality in the 2012 Voluntary Guidelines on tenure governance, failures to mobilize the feminist potential in utilitarian and human rights approaches call for more proactive gender analysis and advocacy when addressing transnational land deals as gendered power struggles.     

Teenage pregnancies and births in Germany: patterns and developments

We study the development of teenage fertility in East and West Germany using data from the German Socioeconomic Panel and from the German Mikrozensus. Following the international literature we derive hypotheses on the patterns of teenage fertility and test whether they are relevant to the German case. We find that teenage fertility is associated with teenage age and education, with the income of the teenager’s family, with migration status, residence in East Germany and aggregate unemployment. Our evidence supports counter-cyclical teenage fertility.     

Investment timing and learning externalities

We study a duopoly model of investment, in which each player learns about the quality of a common value project by observing some public background information, and possibly the experience of his rival. Investment costs are private information, and the background signal takes the form of a Poisson process conditional on the quality of the project being low. The resulting attrition game has a unique, symmetric equilibrium, which depends on initial public beliefs. We determine the impact of changes in the cost and signal distributions on investment timing, and how equilibrium is affected when a first-mover advantage is introduced.     

Optimal agenda-setter timing

Abstract .  We analyze the optimal timing problem of an agenda setter who can propose a project that is then voted on by a committee. The payoff consists of a common stochastic component and an idiosyncratic component that differs among committee members. The agenda setter may be biased for or against the project, relative to the median committee member, and chooses when to call the vote. We analyze how the timing decision depends on the political environment and the bias of the agenda setter. We show that both positively and negatively biased agenda setters can implement decisions that differ from those preferred by the median committee member.     

法治之用:公共支出、税收与经济绩效

法治对经济绩效的影响可以从公共支出和税收两方面解释.税收与再分配所造成的激励扭曲是决定公共支出乃至经济绩效的关键因素.在其他条件不变的情况下,法治的完善会降低经济体的均衡税率水平,减少税收与再分配造成的激励扭曲和总产出损失.在法治与民主的协同作用下,公共支出与社会总产出水平都会得到提高.从现实经济生活来看,法治之用主要体现在两方面:协调经济利益,实现"非自我实施型"交易收益.     

Pricing and regulating affect environmental ethics

Effluent charges and tradeable permits are economically efficient but rarely used. A new explanation for this discrepancy is offered. Pricing may crowd out environmental ethics in the pricing, and via spillovers, also in non-pricing sectors. Pricing may therefore increase pollution, providing a reason why decision-makers tend to reject environmental pricing. Five propositions showing the conditions for counterproductive effects are advanced. They are consistent with available empirical evidence. Regulation by setting standards and subsidies damage environmental ethics less than pricing, because pollution is condoned. Damaging environmental ethics may prevent political action in favor of the environment.     

Coordination,timing and common knowledge

There is tight link between coordination and common knowledge. The role of higher order beliefs in static incomplete information games has been widely studied. In particular, information frictions break down common knowledge. A large body of literature in economics examine dynamic coordination problems when there are timing frictions, in the sense that players do not all move at once. Timing frictions in dynamic coordination games play a role that is closely analogous to information frictions in static coordination games.This paper makes explicit the role of higher order beliefs about timing in dynamic coordination games with timing frictions. An event is said to be effectively known if a player knew the event when he last had an option to change his behavior. The lack of effective common knowledge of the time drives results of dynamic coordination games.     

A game of timing and visibility

We consider the following abstraction of competing publications. There are n players in the game. Each player i chooses a point x_i in the interval [0,1], and a player's payoff is the distance from its point x_i to the next larger point, or to 1 if x_i is the largest. For this game, we give a complete characterization of the Nash equilibrium for the two-player game, and, more important, we give an efficient approximation algorithm to compute numerically the symmetric Nash equilibrium for the n-player game. The approximation is computed via a discrete version of the game. In both cases, we show that the (symmetric) equilibrium is unique. Our algorithmic approach to the n-player game is non-standard in that it does not involve solving a system of differential equations. We believe that our techniques can be useful in the analysis of other timing games.     

The ethics behind efficiency

The normative elements underlying efficiency are more complex than generally portrayed and rely upon ethical frameworks that are generally absent from classroom discussions. Most textbooks, for example, ignore the ethical differences between Pareto efficiency (based on voluntary win-win outcomes) and the modern Kaldor-Hicks efficiency used in public policy assessments (in which winners gain more than losers lose). For the latter to be ethically palatable, society must have in place basic institutions of justice, transparency, and accountability. Normative economics thus requires a pluralist approach that includes considerations of virtue and duty, closer to Adam Smith's Enlightenment conceptions. This surprising finding should embolden economics teachers to engage students with critical thinking problems that are controversial and relevant, and which better prepare students for a complex world.
