    On modeling household labor supply with taxation
    (University College Dublin. School of Economics, 2007-08)
    Discrete choice models of labor supply easily account for nonlinearity and nonconvexity in budget sets caused by tax-benefit systems. As a result, they have become very popular for ex ante evaluations of policy reforms. In this paper, we question whether the degree of flexibility and the implicit household representation in these models are satisfying when confronted to the data. First, we show that attempts to interpret discrete models structurally lead to unnecessary parametric restrictions in most studies. We suggest instead a fully flexible model that retains usual assumptions on economic rationality except regularity conditions on leisure. Indeed, coefficients may account for both tastes and costs of work, possibly making 'preferences' appear nonconvex. Second, we show that the static unitary representation, implicit in most tax policy analyses, is rejected against a more general model with price- and income- dependent preferences. The latter can be rationalized in terms of collective or intertemporal models and offers promising perspectives in these directions. Simulations show that the magnitude of predicted labor supply responses to tax-benefit reforms is sensitive to the underlying household representation.

    Labor Supply Elasticities in Europe and the US
    (University College Dublin. School of Economics, 2011-07) ; ;
    Despite numerous studies on labor supply, the size of elasticities is rarely comparable across countries. In this paper, we suggest the first large-scale international comparison of elasticities, while netting out possible differences due to methods, data selection and the period of investigation. We rely on comparable data for 17 European countries and the US, a common empirical approach and a complete simulation of tax-benefit policies affecting household budgets. We find that wage-elasticities are small and vary less across countries than previously thought, e.g., between .2 and .6 for married women. Results are robust to several modeling assumptions. We show that differences in tax-benefit systems or demographic compositions explain little of the cross-country variation, leaving room for other interpretations, notably in terms of heterogeneous work preferences. We derive important implications for research on optimal taxation.

    Optimal Commodity Taxation and Redistribution within Households
    (University College Dublin. School of Economics, 2011-03) ;
    Using a collective model of consumption, we characterize optimal commodity taxes aimed at targeting speci fic individuals within the household. The main message is that distortionary indirect taxation can circumvent the agency problem of the household. Essentially, taxation should discourage less the consumption of a certain group of goods: those for which the slope of the Engel curves is larger for the targeted person.

    Beans for breakfast? How exportable is the British workfare model?
    (The Institute for the Study of Labor (IZA), 2006-03) ;
    Social assistance and inactivity traps have long been considered amongst the main causes of the poor employment performance of EU countries. The success of New Labour has triggered a growing interests in instruments capable of combining the promotion of responsibility and self-sufficiency with solidarity with less skilled workers. Making-work-pay (MWP) policies, consisting of transfers to households with low earning capacity, have quickly emerged as the most politically acceptable instruments in tax-benefit reforms of many Anglo Saxon countries. This chapter explores the impact of introducing the British Working Families' Tax Credit in three EU countries with rather different labor market and welfare institutions: Finland, France and Germany. Simulating the reform reveals that, while first round effects on income distribution is considerable, the interaction of the new instrument with the structural characteristics of the economy and the population may lead to counterproductive second round effects (i.e. changes in economic behavior). The implementation of the reform, in this case, could only be justified if the social inclusion (i.e. transition into activity) of some specific household types (singles and single mothers) is valued more than a rise in the employment per se.

    A theory of child targeting
    (University College Dublin; School of Economics, 2007-03) ;
    There is a large empirical literature on policy measures targeted at children but surprisingly very little theoretical foundation to ground the debate on the optimality of the different instruments. In the present paper, we examine the merit of targeting children through two general policies, namely selective commodity taxation and cash transfer to family with children. We consider a household that comprises an adult and a child. The household behavior is described by the maximization of the adult’s utility function, which depends on the child’s welfare, subject to a budget constraint. The relative effects of a price subsidy and of a cash benefit on child welfare are then derived. In particular, it is shown that ‘favorable’ distortions from the price subsidies may allow to redistribute toward the child. The framework is extended to account for possible paternalistic preferences of the State. Finally, it is shown that, in contrast to the traditional view, well-chosen subsidies can be more cost effective than cash transfers in alleviating child poverty.

    Tax-benefit revealed redistributive preferences over time : Ireland 1987-2005
    (University College Dublin. School of Economics, 2010-10) ;
    By inverting Saez (2002)'s model of optimal income taxation, we characterize the redistributive preferences of the Irish government between 1987 and 2005. The (marginal) social welfare function revealed by this approach is consistently comparable over time and show great stability despite profound changes in market incomes and important fiscal reforms over the period. Results are robust to numerous checks regarding data, income concepts and elasticities. A comparison with the UK shows marked differences reflecting the narrow political spectrum in Ireland compared to radical changes in British politics over the past 30 years. Some "anomalies" in the revealed social welfare function suggests introducing transfers to the working poor.

    In-work transfers in good times and bad - simulations for Ireland
    (University College Dublin. School of Economics, 2009-12) ;
    In-work transfers are often seen as a good trade-off between redistribution and efficiency, as they alleviate poverty among low-wage households while increasing …nancial incentives to work. The present study explores the consequences of extending these transfers in Ireland, where support for low-wage households has been of limited scope. The employment and poverty effects of alternative policies are analyzed thanks to counterfactual simulations built using a micro-simulation model, the Living in Ireland Survey 2001 and labour supply estimations. Firstly, we study the effect of recent extensions of the existing scheme, the Family Income Supplement (FIS), and of its replacement by the refundable tax credit in force in the UK. Secondly, little is known about the impact of macro-level changes on the distribution of resources at the household level, which is particularly relevant in a country deeply affected by the current economic downturn. We suggest a preliminary analysis of the capacity of alternative in-work transfer scenarios to cushion the negative impact of earnings losses and cuts in the minimum wage.

    No claim, no pain - measuring the non-take-up of social assistance using register data
    (University College Dublin. School of Economics, 2009-12) ; ;
    The main objectives of social assistance bene…fits, including poverty alleviation and labor-market or social reintegration, can be seriously compromised if support is difficult to access. While recent studies point to high non-take-up rates, existing evidence does not make full use of the information recorded by benefi…t agencies. Most studies have to rely on interview-based data, with misreporting and measurement errors affecting the variables needed to establish both bene…fit receipt and benefi…t entitlement. In this paper, we exploit a unique combination of Finnish administrative data and eligibility simulations based on the tax-benefi…t calculator of the Finnish authorities, carefully investigating the measurement issues that remain. We …nd rates of non-take-up that are both substantial and robust: 40% to 50% of those eligible do not claim. Using repeated cross-section estimations for years 1996-2003, we identify a set of stable determinants of claiming behavior and suggest that changes in behavior could drive the observed downward trend in take-up rates during the post-recession period. We discuss the poverty implications of our results.

    How tight are safety-nets in Nordic countries? : evidence from Finnish register data
    (University College Dublin; School of Economics, 2007-08) ; ;
    The non take-up of social assistance benefits due to claim costs may seriously limit the anti-poverty effect of these programs. Yet, available evidence is fragmented and mostly relies on interview-based data, potentially biased by misreporting and measurement errors on both bene…t entitlement and income levels used to assess eligibility. In this paper, we use Finnish administrative data to compare eligibility and actual receipt of social assistance by working-age families during the post-recession period (1996-2003). Possible errors due to time-period issues and discretionary measures by local agencies are carefully investigated. Non take-up is found to be substantial (between 40% and 50%) and increasing during the period. Using repeated cross-section estimations, we identify a set of stable determinants of claiming behavior and suggest that the increasing trend is mainly due to a composition effect, i.e. a decline in the proportion of groups with higher claiming propensity. We…finally discuss the targeting efficiency of the social assistance scheme.
