Inflation and income inequality: a shopping-time aproach: (Forthcoming, Journal of Development Economics)

Our work is based on a simpliÖed heterogenous-agent shoppingtime economy in which economic agents present distinct productivities in the production of the consumption good, and di§erentiated access to transacting assets. The purpose of the model is to investigate whether, by focusing the analysis solely on endogenously determined shopping times, one can generate a positive correlation between ináation and income inequality. Our main result is to show that, provided the productivity of the interest-bearing asset in the transacting technology is high enough, it is true true that a positive link between ináation and income inequality is generated. Our next step is to show, through analysis of the steady-state equations, that our approach can be interpreted as a mirror image of the usual ináation-tax argument for income concentration. An example is o§ered to illustrate the mechanism.

Yet another reason to tax goods

The optimal taxation of goods, labor and capital income is considered in a two period model where: i) private information changes through time; ii) savings are not observed, and; iii) savings a§ect preferences conditional on the realization of types. The simultaneous appearance of these three elements cause optimal commodity taxes to depend on o§-equilibrium savings. As a consequence, separability no longer su¢ ces for the uniform taxation prescription of Atkinson and Stiglitz (AS) to obtain. If preferences are homothetic AS is partially restored: taxes are uniform within periods, however, future consumption is taxed at a higher rate than current consumption.

A politica fiscal no Brasil : limites e contradições : o caso do Estado do Espirito Santo

o estudo pretende contribuir para a análise da realidade brasileira, através do caso do Estado do Espírito Santo, no período compreendido entre 1946 a 1980, tentando demonstrar a dependência financeira dos governos estaduais refletida na perda de receitas próprias e da necessária autonomia para a sua utilização. Numa visão retrospect.iva observa-se uma excessiva tendência à centralização manifestada pelo federalismo brasileiro, principalmente, depois da Reforma Tribut.ária de 1967, que estabeleceu um rigoroso controle da União sobre as receitas tributárias e sobre a ação dos Estados- membros, reduzindo sua autonomia em matéria de legislação tributária. A centralização financeira e política fez com que os go- . , . vernos estaduais perdessem 8S prerrogativasanteriorrnente adquiridas e tivessem limitada sua autonomia em;matéria de politica fiscal. Tentou-se compensar a acentuada redução das receitas tributárias estaduais lnstituindo- se o mecanismo das transferências que, a despeito de suas funç5es redIstributi vas, impõe uma série de exig§ncias e determinações para a sua aplicação. A partir dessa constataç50 passa-se a analisar a política fiscal no Estado do Espírito Santo observando-se as administrações estaduais nesse período. Cheg~-se à conclusão de que as sucessivas crises financeiras ocorridas limitaram a formulação de uma política fiscal estadual. Com isso, constat3-se que os estados passaram a ser rneros agentes administrativos reproduzindo as decis5es maiores formuladas pelo governo federal. Em linhas gerais, tentou-se comprovar a dependência fi--

Tax filing choices for the household under separable spheres bargaining

If household choices can be rationalized by the maximization of a well defined utility function, allowing spouses to file individually or jointly is equivalent to offering the envelope of the two tax schedules. If, instead, household ’preferences’ are constantly being redefined through bargaining, the option to file separately may affect outcomes even if it is never chosen. We use Lundberg and Pollak’s (1993) separate spheres bargaining model to assess the impact of filing options on the outcomes of primary and secondary earners. Threat points of the household’s bargain are given for each spouse by the utility that he or she attains as a follower of a counter-factual off-equilibrium Stackelberg game played by the couple. For a benchmark tax system which treats a couple’s average taxable income as if it were that of a single individual, we prove that if choices are not at kinks, allowing couples to choose whether to file jointly or individually usually benefits the secondary earner. In our numeric exercises this is also the case when choices are at kinks as well. These findings are, however, quite sensitive to the details of the tax system, as made evident by the examination of an alternative tax system.

Taxação diferenciada sobre firmas, má alocação dos recursos e produto de longo prazo

O quanto e como a estrutura tributária adotada por um país pode afetar seu produto de longo prazo? Para tentar responder essa pergunta, usamos um modelo de crescimento neoclássico com plantas heterogêneas desenvolvido por Restuccia e Rogerson (2008). Separando as plantas em três diferentes subgrupos, as pequenas, as médias e as grandes, definimos estrutura tributária como sendo o conjunto de taxas cobradas sobre a receita de cada um dos tipos de planta. Partindo-se então de um equilíbrio de estado estacionário onde as plantas pequenas tem sua receita taxada em 18%, as médias em 30% e as grande em 50%, essa dissertação faz uma série de exercícios numéricos com o intuito de identificar possíveis ganhos/perdas de se alterar a estrutura tributária vigente.

Non-durable consumption and real-estate prices in Brazil: panel-data analysis at the state level

Housing is an important component of wealth for a typical household in many countries. The objective of this paper is to investigate the effect of real-estate price variation on welfare, trying to close a gap between the welfare literature in Brazil and that in the U.S., the U.K., and other developed countries. Our first motivation relates to the fact that real estate is probably more important here than elsewhere as a proportion of wealth, which potentially makes the impact of a price change bigger here. Our second motivation relates to the fact that real-estate prices boomed in Brazil in the last five years. Prime real estate in Rio de Janeiro and São Paulo have tripled in value in that period, and a smaller but generalized increase has been observed throughout the country. Third, we have also seen a recent consumption boom in Brazil in the last five years. Indeed, the recent rise of some of the poor to middle-income status is well documented not only for Brazil but for other emerging countries as well. Regarding consumption and real-estate prices in Brazil, one cannot imply causality from correlation, but one can do causal inference with an appropriate structural model and proper inference, or with a proper inference in a reduced-form setup. Our last motivation is related to the complete absence of studies of this kind in Brazil, which makes ours a pioneering study. We assemble a panel-data set for the determinants of non-durable consumption growth by Brazilian states, merging the techniques and ideas in Campbell and Cocco (2007) and in Case, Quigley and Shiller (2005). With appropriate controls, and panel-data methods, we investigate whether house-price variation has a positive effect on non-durable consumption. The results show a non-negligible significant impact of the change in the price of real estate on welfare consumption), although smaller then what Campbell and Cocco have found. Our findings support the view that the channel through which house prices affect consumption is a financial one.

Extreme poverty and development: the role of state in the assurance of minimal existence conditions

This paper follows the idea of Amartya Sen, Nobel Prize of economic, about the role of State in the assurance of minimal existence condition, and aim to answer how countries of Latin America (specifically Brazil) and countries of Europe (specifically United Kingdom) deal with the assurance of this minimal existence conditions. According to Amartya Sen’s view, development must be seen as a process of expanding substantive freedoms, such expansion being the primary purpose of each society and the main mean of development. Substantive freedoms can be considered as basic capabilities allocated to individuals whereby they are entitled to be architects of their own lives, providing them conditions to “live as they wish”. These basic capabilities are divided by Amartya Sen in 5 (five) kinds of substantive freedoms, but for this article’s purpose, we will consider just one of this 5 (five) kinds, specifically the Protective Safety capability. Protective Safety capability may be defined as the assurance of basic means of survival for individuals who are in extreme poverty, at risk of starvation or hypothermia, or even impending famine. Among the means available that could be used to avoid such situations are the possibility of supplemental income to the needy, distributing food and clothing to the needy, supply of energy and water, among others. But how countries deal whit this protective safety? Aiming to answer this question, we selected the problem of “fuel poverty” and how Brazil and United Kingdom solve it (if they solve), in order to assess how the solution found impacts development. The analysis and the comparison between these countries will allow an answer to the question proposed.

Análise dos critérios de distribuição da cota-parte do ICMS paulista

O texto analisa os critérios que compõem o índice de participação dos municípios paulistas na cota-parte do Imposto Sobre Circulação de Mercadorias e Serviços – ICMS, e também propõe mudanças em sua definição. Esses critérios geram distorções no valor per capita destinado a cada município, caminhando na contramão da justiça fiscal e do equilíbrio federativo. De natureza estadual, o ICMS é o tributo que mais arrecada no país e uma das mais importantes fontes de recursos dos estados e municípios. É partilhado com os municípios conforme definido pela Constituição Federal de 1988: 75% para estado e 25% para municípios. Esses 25% que compõem a cota-parte municipal são distribuídos da seguinte forma: três quartos devolvidos na proporção do valor adicionado de suas operações e um quarto, conforme lei estadual.

Neighborhood feedbacks, endogenous stratification, and income inequality

This paper explores the evolution of the cross-section income distribution in economies where endogenous neighborhood formation interacts with positive within-neighborhood feedback effects. We study an economy in which the economic success of adults is determined by the characteristics of the families in the neighborhood in which a person grows up. These feedbacks take two forms. First, the tax base of a neighborhood affects the leveI of education investment in offspring. Second, the effectiveness of education investment is affected by a neighborhood's in come distribution, reflecting factors such as role model or labor market connection effects. Conditions are developed under which endogenous stratification, defined as the tendency for families wi th similar incomes to choose to form common communities, will occur. When families are allowed to choose their neighborhoods, wealthy families will have an incentive to segregate themselves from the rest of the population. This resulting stratification is supported by house price differences between ricli and poor communities. Endogenous stratification can lead to pronounced intertemporal inequality as different families provide very different interaction environments for offspring. When the transformation of human capital into in come exhibits constant retums to scale, cross-section in come differences may also grow across time. As a result, endogenous stratification and neighborhood feedbacks can interact to produce long run inequality.

On the optimality of the Friedman Rule with heterogeneous agents and non-linear income taxation

We study the optimal “inflation tax” in an environment with heterogeneous agents and non-linear income taxes. We first derive the general conditions needed for the optimality of the Friedman rule in this setup. These general conditions are distinct in nature and more easily interpretable than those obtained in the literature with a representative agent and linear taxation. We then study two standard monetary specifications and derive their implications for the optimality of the Friedman rule. For the shopping-time model the Friedman rule is optimal with essentially no restrictions on preferences or transaction technologies. For the cash-credit model the Friedman rule is optimal if preferences are separable between the consumption goods and leisure, or if leisure shifts consumption towards the credit good. We also study a generalized model which nests both models as special cases.

Yet another reason to tax goods

When, in a dynamic model, choices by an agent : i) are not observed, and; ii) affect preferences conditional on the realization of types, new and unexpected features come up in Mirrlees’ (1971) optimal taxation frame- work. In the simplest possible model where a non-trivial filtration may be incorporated, we show how these two characteristics make it neces- sary for IC constraints to be defined in terms of strategies rather than pure announcements. Tax prescriptions are derived, and we are able to show that uniform taxation prescription of Atkinson and Stiglitz fails to hold, in general. Clean results regarding capital income taxation are not easy to come about because usual assumption on preferences do not allow for determining which constraints bind at the optimum. However, in the most ’natural’ cases, we show that return on capital ought to be taxed.

Tax reform under fiscal stress: a CGE analysis of the Brazilian tax reform

In spite of a general agreement over the distortion imposed by the current Brazilian tax system, attempts to reform it during the last decade have faced several restrictions to its implementation. Two of these restrictions were particular binding: a) fiscal adjustment restriction (public sector debt cannot increase), b) fiscal federalist restriction (revenues from individual states and municipalities cannot decrease). This paper focuses on a specific reform that overcomes in principle the fiscal federalist restriction. Using Auerbach and Kotlikoff (1987) model calibrated for the Brazilian economy, I analyze the short and long run macroeconomic effects of this reform subject to the fiscal adjustment restriction. Finally, I look at the redistributive effects of this reform among generations as a way to infer about public opinion’s reaction to the reform. The reform consists basically of replacing indirect taxes on corporate revenues, which I show to be equivalent to a symmetric tax on labor and capital income, by a new federal VAT. The reform presented positive macroeconomic effects both in the short and long run. Despite a substantial increase in the average VAT rate in the first years after the reform, a majority of cohorts experienced an increase in their lifetime welfare, being potentially in favour of the reform.

The distribution of average and marginal effective tax rates in European Union member states

Macro-based summary indicators of effective tax burdens do not capture differences in effective tax rates facing different sub-groups of the population. They also cannot provide information on the level or distribution of the marginal effective tax rates thought to influence household behaviour. I use EUROMOD, an EU-wide tax-benefit microsimulation model, to compute distributions of average and marginal effective tax rates across the household population in fourteen European Union Member States. Using different definitions of ‘net taxes’, the tax base and the unit of analysis I present a range of measures showing the contribution of the tax-benefit system to household incomes, the average effective tax rates applicable to income from labour and marginal effective tax rates faced by working men and women. In a second step, effective tax rates are broken down to separately show the influence of each type of tax-benefit instrument. The results show that measures of effective tax rates vary considerably depending on incomes, labour market situations and family circumstances. Using single averages or macro-based indicators will therefore provide an inappropriate picture of tax burdens faced by large parts of the population.

Avaliação de impacto do Programa Bilhete Único Intermunicipal do Estado do Rio de Janeiro

Este trabalho objetiva verificar o impacto na renda gerado pelo programa de subsídio tarifário para passageiros de transporte intermunicipal da região metropolitana do Estado do Rio de Janeiro (RMRJ), denominado Programa Bilhete Único Intermunicipal (BUI). Para cálculo do impacto foi utilizada a arrecadação do ICMS do comércio varejista como “proxy” da renda. O método para cálculo do impacto foi o de diferença de diferença (DD) para três definições distintas de grupos de tratamento e controle, considerando o período de janeiro de 2006 a janeiro de 2010 como pré-intervenção e fevereiro de 2010 a dezembro de 2014 como pós-intervenção. A primeira definição comparou a evolução de arrecadação do tributo entre os municípios participantes do programa e os municípios fluminenses situados na região limítrofe à RMRJ como grupo de controle. O segundo exercício manteve o mesmo grupo de controle, porém utilizou apenas os municípios sujeitos à intervenção situados a mais de 30 km de distância da capital Rio de Janeiro como grupo de tratamento. Por fim, como teste de robustez, os grupos de tratamento e controle foram selecionados utilizando o método de pareamento (matching). Através de três variações do modelo de DD para cada definição, foi possível encontrar resultados de impacto positivos na arrecadação de ICMS do comércio varejista para os municípios participantes do programa, em especial para os segundo e terceiro exercícios, o que sugere um aumento na renda de seus habitantes após a introdução do Bilhete Único.
