In this paper we study the e ects of conditional cash transfers in school enrolment and tackling child labour. We develop a dynamic heterogeneous agent general equilibrium model, where households face a set of tradeo s while allocating their children's time in leisure activities, schooling and working. We calibrate the model using data from the Brazilian survey PNAD, before the policy was implemented, in order to quantify the e ects of a conditional transfer. We then evaluate the results of a policy experiment that implements a conditional cash transfer scheme similar to the Brazilian Bolsa Fam lia. Our results suggest that the program, in the long term, is able to substantially increase school registration and reduce child labour and poverty. In addition, we nd out that a progressive conditional cash transfer results is even more e ective in tackling child labour and increasing school enrolment.

Neste trabalho, estudamos os impactos de transfer^encias condicionais de renda sobre o trabalho e a educa c~ao infantis. Para tanto, desenvolvemos modelo din^amico de equil brio geral com agentes heterog^eneos, onde as fam lias enfrentam tradeo s com rela c~ao a aloca c~ao de tempo das crian cas em atividades de lazer, em escolaridade e em trabalhar. O modelo e calibrado usando dados da Pesquisa Nacional por Amostra em Domic lios, de modo que podemos quanti car os efeitos de uma pol tica de transfer^encia de renda. Finalmente, avaliamos o impacto de um pol tica semelhante ao atual Bolsa Fam lia. Nossos resultados sugerem que o programa, no longo prazo, e capaz de induzir um aumento substancial na escolaridade, al em de ser efetivo na redu c~ao do trabalho infantil e da pobreza. Al em disso, mostramos que um programa progressivo de transfer^encia condicional de renda resulta em benef cios ainda maiores.

A partir de meados dos anos 2000, a produção brasileira de etanol voltou a prosperar. Enquanto isso, em 2007 foi anunciada a descoberta de grandes reservas de petróleo na camada pré-sal no litoral brasileiro. Com isso, a perspectiva promissora para a indústria brasileira de etanol começou a dar lugar ao desenvolvimento de petróleo do pré-sal com um ambicioso programa de investimentos. Além disso, entre 2011 e 2014 o Governo adotou uma nova política de preços domésticos da gasolina e diesel, com o objetivo de reduzir as pressões inflacionárias, mas reduzindo gradualmente a competitividade do etanol, além de comprometer a situação financeira da Petrobras, dificultando investimentos no pré-sal. Considerando tais desafios e a importância dos setores de petróleo e etanol para a economia brasileira, este estudo tem como objetivo avaliar os impactos econômicos de longo prazo da exploração do pré-sal, com especial atenção para as consequências sobre o setor de etanol. É realizada uma avaliação dos impactos da política de controle do preço da gasolina do período 2011-2014 sobre o setor de etanol. Um modelo adaptado de equilíbrio geral dinâmico recursivo é empregado no qual o setor do petróleo do pré-sal é adicionado como uma tecnologia backstop. Os resultados sugerem que o estímulo precoce da produção do pré-sal para alcançar a produção de petróleo esperada pelo Governo traz mais custos do que benefícios para a economia brasileira. Constatou-se que sem interferência do governo, a produção de petróleo do pré-sal torna-se competitiva somente após 2025-2035. Com relação ao impacto sobre a indústria do etanol, verificou-se que o desenvolvimento do pré-sal não enfraquece a produção brasileira de etanol. No entanto, a política de controle de preço da gasolina teve um impacto negativo sobre o setor de etanol.

Este artigo analisa a importância dos atrasos portuários para a competitividade da indústria de transformação no Brasil. Com base em estimativas recentes sobre o custo diário dos atrasos comerciais e em bases de dados do Banco Mundial e do GTAP (Global Trade Analysis Project), revela a magnitude destas barreiras sob a forma de seus equivalentes ad valorem. Em seguida, por meio de simulações em equilíbrio geral, estima o impacto da melhoria dos processos aduaneiros sobre o desempenho da indústria de transformação no Brasil, sob diferentes cenários. Os resultados obtidos ressaltam o caráter estratégico da facilitação do comércio para o Brasil e da sua inclusão como item relevante para a agenda de crescimento de longo prazo do país

This thesis contains three chapters. The first chapter uses a general equilibrium framework to simulate and compare the long run effects of the Patient Protection and Affordable Care Act (PPACA) and of health care costs reduction policies on macroeconomic variables, government budget, and welfare of individuals. We found that all policies were able to reduce uninsured population, with the PPACA being more effective than cost reductions. The PPACA increased public deficit mainly due to the Medicaid expansion, forcing tax hikes. On the other hand, cost reductions alleviated the fiscal burden of public insurance, reducing public deficit and taxes. Regarding welfare effects, the PPACA as a whole and cost reductions are welfare improving. High welfare gains would be achieved if the U.S. medical costs followed the same trend of OECD countries. Besides, feasible cost reductions are more welfare improving than most of the PPACA components, proving to be a good alternative. The second chapter documents that life cycle general equilibrium models with heterogeneous agents have a very hard time reproducing the American wealth distribution. A common assumption made in this literature is that all young adults enter the economy with no initial assets. In this chapter, we relax this assumption – not supported by the data – and evaluate the ability of an otherwise standard life cycle model to account for the U.S. wealth inequality. The new feature of the model is that agents enter the economy with assets drawn from an initial distribution of assets. We found that heterogeneity with respect to initial wealth is key for this class of models to replicate the data. According to our results, American inequality can be explained almost entirely by the fact that some individuals are lucky enough to be born into wealth, while others are born with few or no assets. The third chapter documents that a common assumption adopted in life cycle general equilibrium models is that the population is stable at steady state, that is, its relative age distribution becomes constant over time. An open question is whether the demographic assumptions commonly adopted in these models in fact imply that the population becomes stable. In this chapter we prove the existence of a stable population in a demographic environment where both the age-specific mortality rates and the population growth rate are constant over time, the setup commonly adopted in life cycle general equilibrium models. Hence, the stability of the population do not need to be taken as assumption in these models.

Transition to diets that are high in saturated fat and sugar has caused a global public health concern as the pattern of food consumption is a mayor modifiable risk factor for chronic non-communicable diseases Although agri food systems are intimately associated with this transition, agriculture and health sectors are largely disconnected in their priorities policy, and analysis with neither side considering the complex inter relation between agri trade patterns of food consumption health, and development We show the importance of connection of these perspectives through estimation of the effect of adopting a healthy diet on population health, agricultural production trade the economy and livelihoods, with a computable general equilibrium approach on the basis of case studies from the UK and Brazil we suggest that benefits of a healthy diet policy will vary substantially between different populations, not only because of population dietary intake but also because of agricultural production trade and other economic factors

The Caribbean region remains highly vulnerable to the impacts of climate change. In order to assess the social and economic consequences of climate change for the region, the Economic Commission for Latin America and the Caribbean( ECLAC) has developed a model for this purpose. The model is referred to as the Climate Impact Assessment Model (ECLAC-CIAM) and is a tool that can simultaneously assess multiple sectoral climate impacts specific to the Caribbean as a whole and for individual countries. To achieve this goal, an Integrated Assessment Model (IAM) with a Computable General Equilibrium Core was developed comprising of three modules to be executed sequentially. The first of these modules defines the type and magnitude of economic shocks on the basis of a climate change scenario, the second module is a global Computable General Equilibrium model with a special regional and industrial classification and the third module processes the output of the CGE model to get more disaggregated results. The model has the potential to produce several economic estimates but the current default results include percentage change in real national income for individual Caribbean states which provides a simple measure of welfare impacts. With some modifications, the model can also be used to consider the effects of single sectoral shocks such as (Land, Labour, Capital and Tourism) on the percentage change in real national income. Ultimately, the model is envisioned as an evolving tool for assessing the impact of climate change in the Caribbean and as a guide to policy responses with respect to adaptation strategies.

Nicaragua is making progress towards the Millennium Development Goals, but is set to miss a number of targets in 2015. This paper’s general equilibrium analysis shows that it is unfeasible for the government to step up spending in order to meet these targets by the 2015 deadline. Any boost to public spending and financing would have to be front-loaded, which would entail pernicious macroeconomic trade-offs. A more realistic scenario would be to postpone meeting the goals until 2020. In that case, the allocation of public spending would spur economic growth without causing macroeconomic hardships, although the country would nevertheless remain highly vulnerable to external shocks.

This paper develops a structural general equilibrium model to analyse the reactions of the nominal exchange rate and the domestic price level to three types of external shock in emerging economies that have limited access to world capital markets. Although the results depend crucially on the type of external shock, each of the two national balance-sheet parameters considered here —the risk premium and the ratio of external indebtedness— exacerbates the reactions of the two endogenous variables without altering the degree of exchange-rate pass-through (erpt). Moreover, flatter Phillips curves, as observed today in many economies, tend to increase erpt. On the basis of these results, the authorities of emerging economies seeking to stabilize markets and limit erpt are advised to minimize the two risk parameters by applying a flexible inflation-targeting regime.
