Taxes and labor supply: Portugal, Europe, and the United States (Conference version)

I relate hours worked with taxes on consumption and labor. I propose a model and compare its predictions for Portugal, France, Spain, United Kingdom and United States. Hours per worker in Portugal decreased from 35.1 in 1986 to 32.6 in 2001. With only the parameters and the taxes for Portugal, the model predicts the hours worked in 2001 with an error of only 12 minutes from the actual hours. Across countries, most predictions differ from the data by one hour or less. The model is able to explain the trend in hours with only the changes in taxes.

Taxes and labor supply: Portugal, Europe, and the United States

I relate hours worked with taxes on consumption and labor for Portugal, France, Spain, United Kingdom and United States. From 1986 to 2001, hours per worker in Portugal decreased from 35.1 to 32.6. With the parameters for Portugal, the model predicts hours worked in 2001 with an error of only 12 minutes from the actual hours. Across countries, most predictions differ from the data by one hour or less. The model is not sensible to special assumptions on the parameters. I calculate the long run effects of taxes on consumption, hours, capital and welfare for Portugal. I extend the model to discuss implications for Social Security. I discuss the steady state and the transition from a pay-as-you-go to a fully funded system.

Adjusting to external imbalances within the EMU, the case of Portugal

From 1995 to 2010 Portugal has accumulated a negative international asset position of 110 percent of GDP. In a developed and aging economy the number is astonishing and any argument to consider it sustainable must rely on extremely favorable forecasts on growth. Portuguese policy options are reduced in number: no autonomous monetary policy, no currency to devaluate, and limited discretion in changing fiscal deficits and government debt. To start the necessary deleveraging a remaining possible policy is a budget-neutral change of the tax structure that increases private saving and net exports. An increase in the VAT and a decrease in the employer’s social security contribution tax can achieve the desired outcome in the short run if they are complemented with wage moderation. To obtain a substantial improvement in competitiveness and a large decrease in consumption, the changes in the tax rates have to be large. While a precise quantitative assessment is difficult, the initial increase in the effective VAT rate needed to allow the social security tax to decrease by 16 percentage points (pp) is approximately 10 pp. Such a large increase in the effective VAT rate could be obtained by raising most of the reduced VAT rates to the new general VAT rate of 23 percent. The empirical analysis shows that over time the suggested tax swap could generate surpluses and improve the trade balance. A temporary version of the suggested tax-swap has the attractiveness to achieve a sharper increase in the private saving rate maintaining the short run gains in competitiveness. Finally, the temporary version of the fiscal devaluation could be the basis for an automatic stabilizer to external imbalances within a monetary union.Portugal has been running large current account deficits every year since 1995. These deficits have accumulated to an astonishing 110 percent of GDP negative external asset position. The sustainability of such a large external position is questionable and must rely on fantastic productivity growth expectations. The recent global financial crisis appears to have anticipated the international investors reality check on those future expectations with the result of a large increase in the cost of external financing. Today the rebalancing of the current account through an increase in national savings and an improvement in competitiveness must be at the top of the Portuguese authorities “to do” list as the cost of a pull out from international investors is of the order of 10% of GDP. The external rebalancing is difficult as the degrees of freedom of the Portuguese authorities are limited in number: they have no autonomous monetary policy, no currency to devaluate, and little discretion in fiscal policy as deficit limits and debt targets are set by the Stability Growth Pact and the postcrisis consensus on medium-term fiscal consolidation. One possibility that remains is to change the fiscal policy mix for a given budget deficit. The purpose of this paper is to explore the effects of a “fiscal devaluation”1 obtained through a tax swap between employers’ social security contributions and taxes on consumption2. The paper begins by illustrating Portugal���s current account evolution during the euro period. The second section section lays out a model to offer a qualitative assessment of the dynamic outcomes of the the tax swap. I show that the suggested tax swap can in theory achieve the desired outcomes in terms of competitiveness and consumption if complemented with moderation (stickiness) in wages. I also study the effects of a temporary version of the tax swap and show that it achieves a sharper improvement in the current account that accelerate the rebalancing. The third section moves to the empirical analysis and estimates the likely effects of the tax swap for the Portuguese economy. The fourth section concludes.

Mapping Mediterranean Portugal: Pastoral and Counter-pastoral

This article focuses on the different images of Mediterranean Portugal developed by three important Portuguese social scientists of the 20th century: the geographer Orlando Ribeiro, the ethnologist Jorge Dias and the social anthropologist José Cutileiro. The article argues that these different images stem from different ideological attitudes towards the countryside, ranging from pastoral to counter-pastoral, and are also related to different ways of addressing the links between the countryside and national identity.

Avaliação de ações municipais de combate a vetores da dengue na região de São José do Rio Preto, São Paulo, 1989 a 1995

O objetivo do trabalho é medir as coberturas das atividades municipais de controle de Aedes aegypti e/ou Aedes albopictus, o casa-casa e o arrastão, realizadas entre 1989 e 1995 na região de São José do Rio Preto, São Paulo e avaliar a correlação cruzada entre elas e os Índices de Breteau (IB). Para o municípios com até 50.000 imóveis as coberturas conjuntas das atividade casa-casa e arrastão foram em sua maioria adequadas e as coberturas do casa-casa apresentaram correlação cruzada negativa com os IB. Para município sede (maior que 50.000 imóveis) estas coberturas não apresentaram correlação com os IB. Em geral as coberturas foram inversamente proporcionais ao tamanho dos municípios. Para todas as faixas de tamanho de municípios, os arrastões não apresentaram correlação com os IB, mostrando-se ineficazes.

Phlebotominae (Diptera: Psychodidae) de Lagoas, município de Buriticupu, Amazônia Maranhense. I - Riqueza e abundância relativa das espécies em área de colonização recente

Este estudo determinou a riqueza de espécies e a abundância relativa dos flebotomíneos da comunidade de Lagoas, em Buriticupu, na Amazônia Maranhense. O estudo consistiu na captura de formas adultas com auxílio de armadilhas luminosas tipo CDC e armadilha de Shannon, das 18 às 6 horas, uma vez por mês, de dezembro/95 a janeiro/97, em ambiente florestal e extraflorestal (peri e intradomicílios). No total, capturou-se 9.392 espécimens (4.302 machos e 5.090 fêmeas) distribuídos em 38 espécies (1 Brumptomyia e 37 Lutzomyia). A riqueza e abundância de espécies foram maiores na mata, seguida do peri e intradomicílio. Na mata, as espécies mais freqüentes foram Lutzomyia whitmani (64,9%), L. migonei (27%) e L. serrana (3,6%). No peridomicílio, predominaram L. evandroi (55,4%), L. whitmani (33,4%) e L. migonei (6,4%) e no intra, L. evandroi (97,9%). O predomínio no ambiente silvestre resulta das potencialidades ainda encontradas nas glebas remanescentes da floresta tão explorada pelas atividades madeireira e agropecuária. Por outro lado, a peridomiciliação de 7,7% das espécies reverteu-se de grande importância epidemiológica, haja visto a existência de pacientes com leishmanioses que julgam ter adquirido a infecção nas proximidades de suas habitações.

The institutions of archaic post-modernity and their organizational and managerial consequences: The case of Portugal

The long march of modernization of the Western societies tends to be presented as following a regular sequence: societies and institutions were pre-modern, and then they were modernized, eventually becoming post-modern. Such teleology may provide an incomplete or distorted narrative of societal evolution in many parts of the world, even in the ‘post-modern heartland’ of Western Europe, with Portugal being a case in point. The concept of archaic post-modernity has been developed by a philosopher, José Gil, to show how Portuguese institutions and organizations combine elements of pre-modernity and post-modernity. The notion of an archaic post-modernity is advanced in order to provide an alternative account of the modernization process, which enriches discussion of the varieties of capitalism. Differences in historical experiences create singularities that may be considered in the analysis of culture, management and organization.
