Pension and child care policies with endogenous fertility

This paper presents an examination of effects of a child allowance on fertility under a pay-as-you-go pension system. In these analyses, the child allowance is financed by taxation of two kinds: an income tax and a consumption tax. Comparative static analyses show that a child allowance financed by income tax revenues can always raise fertility. Similarly with income tax, a child allowance financed by consumption tax can always raise fertility. Furthermore, our paper presents examination of optimal child allowance and transfer for older people.     

Military reserves and social welfare

We consider the contribution of reserves to the efficient mobilization of military manpower. Our analysis suggests that offering recruits an option to serve as reservists enhances social welfare if there is a sufficiently strong relationship between recruit performance in the military and their expected civilian income.     

Public pension and household saving: Evidence from urban China

We relate household savings to pension reform, to explain the high household savings rates in urban China from a new perspective. We use the exogenous – policy-induced – variation in pension wealth to estimate explicitly the impact of pension wealth on household savings, and obtain evidence of a significant offset effect of pension wealth on household savings. Although the size of the effect depends on the parameter values assumed, the finding that household savings are affected by pension reform is robust. Our estimates show that, under plausible scenarios, pension reform boosted household savings rates in 1999 by about 6–9 percentage points for cohorts aged 25–29 and by about 2–3 percentage points for cohorts aged 50–59. Our results also indicate that declining pension wealth reduces expenditure on education and health more than on other consumption items.     

On the credibility of harassment in the insider—outsider model

In a well-known version of the insider-outsider model, the decision by outsiders not to underbid follows from the threats made by insiders to harass new entrants, thereby raising the entrants' disutility of work. It has been argued, however, that the harassment threat is not credible, at least in the one-period case. In the current paper we explore this claim, concluding that the existence of a social convention, together with associated social pressure effects, provides a possible explanation of the credibility of the harassment threat. Moreover, we suggest that such a convention is likely to play a role even in a multi-period analysis.     

Training, search and wage dispersion

This paper combines on-the-job search and human capital theory to study the coexistence of firm-funded general training and frequent job turnovers. Although ex ante identical, firms differ in their training decisions. The model generates correlations between various firm characteristics that are consistent with the data. Wage dispersion exists among ex ante identical workers because workers of the same productivity are paid differently across firms, and because workers differ in their productivity ex post. Endogenous training breaks the perfect correlation between work experience and human capital, which yields new insights on wage dispersion and wage dynamics.     

On the time allocation of married couples since 1960

In the last half a century, married females more than doubled their workforce participation and significantly reduced their time spent on home production. Using a model of family decision making with home production and individual earnings heterogeneity, we subject two prominent explanations for this aggregate change, namely, the evolution of the gender earnings gap and the cost of home appliances, to quantitative tests with respect to changes in participation for disaggregated groups of couples and trends in time spent in leisure and home production activities. We find that both forces are needed to understand the evolution of married female time allocation over time, although the falling cost of home appliances is a dominant explanation for the time allocation outside of workplace, while the gender earnings gap is the dominant explanation for the workforce participation decision.     

Public pricing of final and intermediate goods in the presence of externalities

The purpose of this paper is to investigate the impact of externalities on pricing decisions by a public or a private regulated firm selling both final and intermediate goods. The externalities generate feedbacks in demand that affect both consumers and producers. The model is very general in that it does not impose constant returns to scale on private production, allows for distributional effects of both the publicly determined prices and private sector profits, and captures the general equilibrium effects of public pricing. Socially optimal pricing rules are derived, and the relation of the results with previous models of pricing in the presence of externalities is investigated.     

Are there dual labor markets in Chile?: empirical evidence

In this paper we use a switching regression method to test the hypothesis that segmentation in the Chilean labor market exists. The results support the labor segmentation hypothesis and consequently they contradict those of Corbo and Stelcner (1983). The explanation for this is that we do not make any a priori definition of the population, as Corbo and Stelcner do. In fact, our results show that any a priori definition of the sample will lead to rejecting the segmentation hypothesis.     

Piece rates for professors

Using panel data, we demonstrate a 50% increase in research productivity following a dramatic increase in the piece rate paid for articles by a major Chinese University. The increased productivity comes exclusively from those who were already research active.     

Uniqueness of stationary equilibria in bargaining one-dimensional policies under (super) majority rules

We consider negotiations selecting one-dimensional policies. Individuals have instantaneous preferences represented by continuous, concave and single-peaked utility functions, and they are impatient. Decisions arise from a bargaining game with random proposers and (super) majority approval, ranging from the simple majority up to unanimity. We provide sufficient conditions that guarantee the existence of a unique stationary subgame perfect equilibrium, and we provide its explicit characterization. The uniqueness of the equilibrium permits an analysis of the set of Pareto optimal voting rules. For symmetric distributions of peaks and uniform recognition probabilities unanimity is the unanimously preferred majority rule.     

Heterogeneity and convergence of regional inflation (prices)

It is generally thought that members in a monetary union experience a similar level of inflation. This paper verifies this conventional belief. Using regional data, we present statistical evidence of heterogeneous inflation in Japan. Not only does the average inflation differ significantly across regions, but regional inflation responds differently to common economic and monetary factors. Furthermore, we show no evidence of price convergence in the entire group of regions although there is some evidence of convergence in subgroups. These results suggest that diversified regional inflation can exist within a monetary union.     

Biogeographical conditions, the transition to agriculture and long-run growth

We use new data on the timing of the transition to agriculture, developed by Putterman and Trainor (2006), to test the theory of Diamond (1997) and Olsson and Hibbs (2005) that an earlier transition is reflected in higher incomes today. Our results confirm the theory, even after controlling for institutional quality and other geographical factors. The date of transition is correlated with prehistoric biogeography (the availability of wild grasses and large domesticable animal species). The factors conducive to high per capita incomes today are good institutions, an early transition to agriculture, access to the sea and a low incidence of fatal malaria. Geographical influences have been at work in all of these proximate determinants of per capita income.     

Rents, military elites, and political democracy

In autocratic regimes the military elite is in a position to extract rents, because without the support of the military the government is in general not able to sustain itself. In this paper, we empirically confirm the negative relation between transfers to the military and the degree of democracy for developing countries. We use an instrumental variable approach to account for the simultaneity that arises since the degree of democracy is itself a function of transfers to the military.     

Redistribution and the marginal cost of public funds

Discussions of the marginal cost of public funds with distortionary taxation are often cast in the framework of a one-consumer economy, while the main justification of distortionary taxes is that they are needed for redistribution. This paper analyzes the issue in a model with heterogeneous consumers and a linear income tax, focusing on the tradeoff between labour market distortions and the redistribution from high-wage to low-wage workers. In an optimal tax system the MCF will be the same for all sources of funds and under certain assumptions less than one. Without optimality the MCF will in general differ between different sources of finance.     

Growth, welfare and optimal trade taxes: a fallacy of composition

Optimal export taxation rules out the possibility of immiserizing growth in a two-country world. Thus, productivity increases in the exporting sector must be welfare improving. This paper shows that in a multicountry world such reasoning commits a fallacy of composition. Simultaneous growth of exporting nations can lead to welfare losses in the presence of unilaterally optimal export taxes. Also, optimal export taxes can decline in response to such growth. This result further strengthens the possibility of perverse welfare movements. Thus, standard policy recommendations of increasing productivity in the exporting sector may lead to unintended and self-defeating outcomes.     

The forecasting properties of survey-based wage-growth expectations

We evaluate survey-based wage-growth expectations and find that they are neither unbiased nor efficient forecasts. Concerning out-of-sample forecast precision, survey participants generally perform worse than a constant forecast. Caution should accordingly be exercised when relying on these data for policymaking.     

Political regimes and income inequality

We construct a theoretically-motivated model of income inequality. Through a pooled regression on an international panel, we demonstrate that political regime (whether extractive, redistributive, or reinvestment-oriented) correlates with within-country income inequality.     

Barriers to entry, deregulation and workplace training: A theoretical model with evidence from Europe

We study the impact of regulatory barriers to entry on workplace training. We develop a model of training in imperfectly competitive product and labour markets. The model indicates that there are two contrasting effects of deregulation on training. As stressed in the literature, with a given number of firms, deregulation reduces the size of rents per unit of output that firms can reap by training their employees. Yet, the number of firms increases following deregulation, thereby raising output and profit gains from training and improving investment incentives. The latter effect prevails. In line with the predictions of the theoretical model, we find that the substantial deregulation in the 1990s of heavily regulated European industries (energy, transport and communication) increased training incidence.
