Income Distribution Dynamics with Endogenous Fertility

Developing countries with highly unequal income distributions, such as Brazil or South Africa, face an uphill battle in reducing inequality. Educated workers in these countries have a much lower birthrate than uneducated workers. Assuming children of educated workers are more likely to become educated, this fertility differential increases the proportion of unskilled workers, reducing their wages, and thus their opportunity cost of having children, creating a vicious cycle. A model incorporating this effect generates multiple steady-state levels of inequality, suggesting that in some circumstances, temporarily increasing access to educational opportunities could permanently reduce inequality. Empirical evidence suggests that the fertility differential between the educated and uneducated is greater in less equal countries, consistent with the model.     

Backward Intergenerational Goods and Endogenous Fertility

This paper characterizes the consequences of introducing the public provision of intergenerational goods to the elderly in a model with endogenous fertility. With exogenous fertility, it has been shown that the government can mandate the first‐best outcome by simply imposing the socially optimal transfer. By contrast, with endogenous fertility, the government can no longer enforce this outcome. This is due, in part, to the effects of mandatory provision on the birth rate. However, taxes may still have a salubrious effect on social welfare as they can eliminate particularly bad equilibria.     

延迟退休、内生出生率与经济增长

本文构建了一个包含延迟退休和内生出生率的OLG模型,考察延迟退休对人口出生率和经济增长的影响。研究发现,在新古典增长框架和内生增长框架下,无论是现收现付社会保障制度还是完全基金社会保障制度,延迟退休都使得均衡状态出生率上升。延迟退休对内生人口出生率的影响主要通过以下两个渠道实现:一方面,延迟退休使得老年时期收入增加,这会减少年轻时期的储蓄,年轻时期选择更少的时间劳动,投入更多的时间抚育子女,这使得人口出生率上升;另一方面,延迟退休使得资本存量减少,为实现年轻时期的消费,个体必须提供更多的劳动,这使得人口出生率下降。在本文的框架下,延迟退休对人口出生率的正向影响大于负向影响。延迟退休对经济增长的影响依赖于经济增长模式。在新古典经济增长模式下,延迟退休通过提高人口出生率渠道使得经济增长率上升。在内生经济增长模式下,延迟退休通过人口出生率渠道对经济增长的正向影响不足以弥补其通过资本积累渠道对经济增长的负向影响。     

Endogenous Fertility, Income Distribution, and Growth

This article analyzes the interaction between growth and fertility via income distribution in a model in which fertility decisions are motivated by old-age support. It provides an explanation of the demographic transition of an economy from a stage of increasing fertility and low growth to a stage of low fertility, high human capital investments, and high growth.     

The Optimal Level of Debt in an OLG Model with Endogenous Fertility

Abstract. In the present work we extend Diamond's OLG model by allowing for endogenous fertility and look at the consequences of such an extension on the rules for optimal public debt issuing. In particular, we show that the condition according to which the rate of growth of population should be higher than the interest rate is no longer sufficient for obtaining welfare improvements via debt increases and that the level of optimal debt is, ceteris paribus, lower than the one arising with exogenous fertility. Finally, a sensitivity analysis shows that the optimal level of debt is higher the lower the capital share, the higher individuals' degree of patience, the bigger the child‐rearing cost and the lower the preference for children. On policy grounds we argue that debt‐tightening policies may be optimal in the long run provided that the cost of rearing children does not increase (or, if anything, does decrease).     

Geography and Demography: New Economic Geography With Endogenous Fertility

To explain the links between demographics and economic integration, we construct a new economic geography model with endogenous fertility. Labour mobility across regions results in more people flowing into highly populated regions, but lowers fertility rates there. Finally, regions are divided into one very large region with a higher real wage and another small region with a lower real wage, a higher fertility rate and a supply of workers to the large region. The population growth path resembles a logistic curve in the early phase, but population decreases in the last phase. Economic integration leads to population concentration and decreases population size.     

On Endogenous Efficiency in Public and Private Firms

This paper reconsiders a model proposed by De Fraja (1993) to compare public and private production under complete and incomplete information. It is argued, in contrast to previous results, that such a model provides no convincing grounds to sustain the productive superiority of public ownership. It is also suggested that meaningful comparisons of efficiency require settings where differences in ownership imply different implementation constraints.     

Income Taxation, Endogenous Factor Prices and Production Efficiency

In an analysis of a two‐type income tax model with endogenous wages, this paper shows that production efficiency is violated in the optimum with (i) non‐linear and (ii) linear income taxation if and only if a distortionary tax schedule is implemented. These findings complement earlier results of the literature. In passing, it is also shown that optima with non‐linear redistributive income taxation cannot be identified with the redistributive regime if the assumption of endogenous wages is taken seriously.     

Efficiency Defense in EU and US Horizontal Merger Control if Costs are Endogenous

If fixed costs are endogenous, following from profit maximization, horizontal mergers are always profitable. They cause the price to rise and consumer surplus to decrease. A case of horizontal merger in which, according to the requirement of US and EU Merger Guidelines for an efficiency defense to be acceptable, the price declines or remains constant does not exist and therefore cannot be expected by profit maximizing partners to arise following a merger. Merger control should be guided by focusing on total welfare. Permitting cooperation in R&D, although profitable, is likely to be detrimental to welfare.     

The Effect of Endogenous Regulation on Telecommunications Expansion and Efficiency in Latin America

I examine the effect of reform on telecom performance using a second-generation regulatory framework index and panel data techniques to test how regulatory governance affected sector performance in 22 Latin American countries during the period 1980–1997. Sound regulatory governance in telecommunications has a positive impact on network expansion and efficiency, in both the static and dynamic specifications. Openness of markets to competition and divestment of former state-owned telco operators also contributed positively to better sector performance. The dynamic specification shows that past performance has its own strong effect on present (and perhaps future) performance.     

Endogenous Lobby Formation and Endogenous Environmental Protection with Unilateral Tariff Reduction

This paper studies how one country’s decision to liberalize trade affects the political economic structure that determines environmental policy in another country. By constructing a political economy model in which the formation of lobby groups and environmental policy are endogenously determined, we show that unilateral tariff reductions by a large country importing a polluting good will generate a lobby group with a relatively lower cost of organization in a small country exporting that good. A formulated lobby demands an inefficient environmental policy, and hence, the small country’s environmental regulations become less efficient. Then, we show that when a lobby already exists, unilateral tariff reductions result in the formation of a rival lobby and consequently make the small country’s environmental policy more efficient.     

Compliance with Endogenous Audit Probabilities

In this paper, we study the effect of endogenous audit probabilities on reporting behavior in a face‐to‐face compliance situation, such as at customs. In an experimental setting in which underreporting has a higher expected payoff than truthful reporting, we find an increase in compliance of about 80 percent if subjects have reason to believe that their behavior towards an officer influences their endogenous audit probability. Higher compliance is driven by considerations about how their own appearance and performance affect their audit probability, rather than by the social and psychological effects of face‐to‐face contact.     

Endogenous Persuasion with Costly Verification

In this paper, I study a situation in which a sender tries to persuade a receiver with evidence that is generated via public or private experimentation. Under public experimentation, any experimental outcome is revealed, and under private experimentation the sender can hide adverse outcomes. The sender can design the properties of the experiments. The receiver chooses whether to verify at a cost the design of the experiment with which the revealed outcome was generated. I find that communication breaks down under public experimentation if there is no restriction on the experiment's design, and that persuasion is possible under private experimentation.     

Committee Design with Endogenous Information

Identical agents gather costly information, and then aggregate it through voting. Because information is a public good, information is underprovided relative to the social optimum. A "good" voting rule must give incentives to acquire information, as well as aggregate information efficiently. A voting rule that requires a large plurality (in the extreme, unanimity) to upset the status quo can be optimal only if the information available to each agent is sufficiently accurate. This result is independent of the preferences of voters and of the cost of information.     

Multi-issue Bargaining with Endogenous Agenda

The first part of this paper shows that in a noncooperative bargaining model with alternating offers and time preferences the timing of issues (the agenda) matters even if players become arbitrarily patient. This result raises the question of which agenda should come up endogenously when agents bargain over a set of unrelated issues. It is found that simultaneous bargaining over “packages” should be a prevailing phenomenon, but we also point to the possibility of multiple equilibria involving even considerable delay.

Public Policy with Endogenous Preferences

Public policy may influence norms and preferences. By altering the payoffs associated with different preferences, public policy may influence the distribution of these preferences in the population. Such interdependence between policy and preferences may limit (or enhance) the effectiveness of different policies. We demonstrate this idea with a simple model of subsidizing contributions to a public good. While the short‐run effect of such a subsidy will be an increase in the overall contribution, the subsidy triggers an endogenous preference change that results in a lower level of contribution to the public good, despite the explicit monetary incentives to raise that level.     

A Ricardian Model with Endogenous Comparative Advantage and Endogenous Trade Policy Regimes

This paper develops a Ricardian model with transaction costs and endogenous and exogenous comparative advantages. It shows that the level of division of labour and trade increases as transaction conditions improve. It identifies the conditions for trade negotiations that result in zero tariff rates and the conditions for the coexistence of unilateral tariff protection and unilateral laissez faire policies. The model may explain the policy transformation of some European governments from Mercantilism to laissez faire in the 18th and 19th century and policy changes in developing countries from protection tariff to trade liberalization and tariff negotiation.     

Endogenous Stackelberg equilibria with incomplete information

In this paper, the endogenous order of quantity decision is studied in a duopoly model with incomplete information. One firm knows the state of the demand curve while the other firm remains uninformed. Firms have to commit to a quantity in one out of two periods. While, a priori, simultaneous-move Cournot equilibria are possible, only Stackelberg equilibria, with either the informed or the uninformed firm moving first, emerge endogenously.     

Environmental Enforcement with Endogenous Ambient Monitoring

We consider an inspection game between n polluting firms and an environmental enforcement agency. If the cost of monitoring ambient pollution is low enough, the optimal inspection policy consists in imposing the maximal possible fine, and mixing between observing ambient pollution and not conducting any inspection at all. However, with stringent upper limits on the fine, the agency mixes between observing ambient pollution and inspecting all firms. The observation of ambient pollution is always followed by sequentially rational firm inspections. Comparisons with Franckx (2002a, Journal of Environmental Economics and Management 43, 71–92, 2002b, Topics in Economic Analysis Policy 2(1), Article 1) show that commitment power has a very strong impact on the value of prior information.
