A Comparison of Optimal Tax Policies when Compensation or Responsibility Matter

This paper examines optimal redistribution in a model with high- and low-skilled individuals with heterogeneous tastes for labor. We compare the extent to which optimal policies based on different normative criteria obey the principles of compensation (for differential skills) and responsibility (for preferences for labor) when labor supply is along the extensive margin. With heterogeneity in skills and preferences, traditional Welfarist criteria including Utilitarianism present unappealing policy recommendations in some scenarios as they fail to take compensation and responsibility issues into account. Criteria from the social choice literature perform better in this regard in first-and second-best. More importantly, these equality of opportunity criteria push the second-best policy away from an Earned Income Tax Credit and in the direction of a Negative Income Tax.optimal income taxation, equality of opportunity, heterogeneous preferences for labor

A comparison of optimal tax policies when compensation or responsibility matter

This paper examines optimal redistribution in a model with high and low-skilled individuals with heterogeneous tastes for labor, that either work or not. With such double heterogeneity, traditional Welfarist criteria including Utilitarianism fail to take the compensation-responsibility trade-off into account. As a response, several other criteria have been proposed in the literature. This paper is the first to compare the extent to which optimal policies based on different normative criteria obey the principles of compensation (for differential skills) and responsibility (for preferences for labor), when labor supply is along the extensive margin. The criteria from the social choice literature perform better in this regard than the traditional criteria, both in first and second best. More importantly, these equality of opportunity criteria push the second best policy away from an Earned Income Tax Credit and in the direction of a Negative Income tax.optimal income taxation, equality of opportunity, heterogeneous preferences for labor

Population Growth and Customary Law on Land: The Case of Cordillera Villages in the Philippines

This paper examines how a traditional village deals with the consequences of population growth. The increase in population demands more intensive use of the land which requires the transformation of commonly-owned land into privately-owned land. Customary law contains clear prescriptions about the circumstances under which a couple can privatize land. We estimate this land accumulation rule using date from two villages in the Cordillera Region of the Philippines. In order to study the evolution of the distribution of land, we model the inheritance practices of the community which constitutes another aspect of customary law. Finally, we use the model to show that despite the flexibility of the customary law on land, the present rapid growth of the population given the limited availability of land leads to its breakdown. This could be avoided only if seven out of ten children are able to make a living from occupations other than farming.Population Growth

Measuring Intergenerational Mobility and Equality of Opportunity

This paper explores the link between the measurement of intergenerational mobility and the notion of equality of opportunity. We show how recently proposed theories of equality of opportunity can be meaningfully adapted to the intergenerational context. This throws a new light on the interpretation of existing mobility measures: these may be interesting to measure mobility as movement, but they are inadequate to capture the notion of equality of opportunity. We propose some new mobility measures, which start from the idea that the intergenerational transition matrix gives useful information about the opportunity sets of the children of different social classes. These measures are used in an empirical illustration to evaluate the degree of inequality of opportunity in the US, Great Britain and Italy.

Equality of opportunity versus equality of opportunity sets

We characterize two different approaches to the idea of equality of opportunity. Roemer's social ordering is motivated by a concern to compensate for the effects of certain (non-responsibility) factors on outcomes. Van de gaer's social ordering is concerned with the equalization of the opportunity sets to which people have access. We show how different invariance axioms open the possibility to go beyond the simple additive specification implied by both rules. This offers scope for a broader interpretation of responsibility-sensitive egalitarianism.

Equality of Opportunity and Kernel Density Estimation: an Application to Intergenerational Mobility

When economists talk about equality, they typically have equality of outcomes, like welfare or income in mind. However such a view of equality is not entirely satisfactory and theories of equality of opportunity have been developed and proposed as an alternative. While there has been some theoretical discussion of equality of opportunity in the public choice literature, the empirical implementation of many of these issues has been limited. In this paper we develop a nonparametric estimator of the opportunity sets facing individuals with different characteristics. This estimator allows us to visualise the choices available to individuals of different types. We then use this estimator to reexamine the intergenerational transmission process. Our estimates indicate that even for children who exhibit the same degree of responsibility, those from richer families earn substantially more than those from poorer families
