The literature measuring the magnitude of the fiscal multiplier has a considerable consensus that the stimulative effects of fiscal instruments depends on the current state of economic activity, whether it is expanding or facing a recession. However, none of the previous works studied how the nature of an economic downturn, if the economy is facing an adverse supply/demand shock, affects the effectiveness of fiscal expansions. We introduce in a simple New Keynesian model with a rich description of fiscal policy, the assumption of imperfectly informed policymakers (fiscal and monetary) to approach the question. Our results point out the existence of disparate effects of fiscal policy depending on whether the economy is facing a demand or a supply recession. Yet, we find out that cuts in taxes are an effective tool to counter the effects of adverse shocks on economic activity and aggregate consumption.

Value-at-Risk was estimated using the technique of wavelet decomposition with goal to analyze the frequency components' impacts on variances of daily stock returns, and on forecasts. Daily returns of twenty-one shares of the Ibovespa and daily returns of twenty-two shares of the DJIA were used. The model was applied to the reconstructed returns to model and establish the prediction of conditional variance, applying the rolling window technique. The Value-at-Risk was then estimated, and the results showed that the DJIA shares showed more efficient market behavior than those of Ibovespa. The differences in behavior induces to affirm that VaRs, used in the analysis of financial assets from different markets with different governance premises, should be estimated by series of returns reconstructed by aggregations of components of different frequencies. A set of back-testing was applied to confront the estimated , which demonstrated that the estimation of models are consistent.

Minimum tracking error portfolios are often implemented by portfolio managers in order to track the performance of a benchmark asset in terms of risk and return. This note provides an analytical derivation of the minimum tracking error portfolios of excess returns on a benchmark by relying on the regression-based approach to portfolio weights proposed in Kempf and Memmel (2006). This approach allows estimating the weights of the minimum tracking error portfolios by means of a simple OLS regression.

The Bolsa Familia CCT Program (BFP) has successfully reduced poverty in Brazil. However, the theoretical literature on associated economic incentives is scarce. A mechanism-design analysis identifies problems of adverse selection and moral hazard in the BFP. The paper proposes simple improving incentive-mechanisms. The Citizens’ Contribution Mechanism (CCM) requires beneficiaries to devote time to the PBF encouraging recipients with higher income to leave. The Graduation Mechanism (GM) offers financial incentives to ensure sustainable emancipation of qualified beneficiaries. The Human Capital Incentive Mechanism (HCM) increases transfers to efficient municipalities. We show that the CCM solves the adverse selection problem, the GM solves the moral hazard problem of beneficiaries and the HCM solves a moral hazard problem of local managers. A simulation based on 2010 census data shows that the mechanisms allow, within 6 years, significant increases in the reach and precision of the PBF and yields cost reductions of over R$4.6 billion.

Plano Real put an end to hyperinflation in 1994 and significantly altered price-setting behavior in Brazil. This paper investigates the impact of Plano Real on search frictions. We estimate a nonsequential search model for homogeneous goods to structurally retrieve consumers' search costs. The dataset comprises 11,673 store-level price quotes collected from 1993 to 1995 by FIPE to calculate the Consumer Price Index (CPI) in the city of São Paulo. The strategy consists of using Plano Real as a structural breakpoint in the data. We estimate the model splitting the data into before (Jan-93 to Jun-94) and after (Aug-94 to Dec-95) the plan, and we find evidence on first-order stochastic dominance of the search-cost distribution of the former into the latter; that is, search costs are higher during hyperinflation. The majority of consumers search only once or twice before buying an item, but this share is marginally higher during hyperinflation (84% vs 79%). In addition, after Plano Real, a larger share of consumers are willing to quote prices in all stores before committing to a purchase. We also document evidence of the effect of the plan on shrinking price-cost margins. When searching is less costly, stores lose market power.

This paper attempts to accommodate the government into Dubey, Geanakoplos and Shubik (2005) framework in an explicit way, and proves that a non-trivial equilibrium exists. By non-trivial equilibrium, we mean an equilibrium where there exists trading in the financial markets and some private borrower defaults. The government, characterised by its spending and tax plansfootnote{Both are assumed to be exogenous like in Gale (1990).}, enters our economic model by trading financial assets in order to balance its budget. Proof of existence is made by considering a generalised game `a la Debreu (1952)footnote{Already well known in the GEI literature.}, and its non-triviality is obtained by using the non-differentiable optimisation theory.
本文试图将政府以一种显式的方式纳入Dubey, Geanakoplos和Shubik(2005)的框架，并证明了一个非平凡均衡的存在。所谓非平凡均衡，我们指的是金融市场上存在交易和一些私人借款人违约的均衡。政府以其支出和税收计划footnote{两者都被认为是外生的，就像Gale(1990)一样。}为特征，通过交易金融资产来平衡预算，从而进入我们的经济模式。通过考虑一个广义赛局 la Debreu (1952) footnote{在GEI文献中已经很有名了。}来证明其存在性，并通过使用不可微优化理论获得其非平凡性。

Despite the fact of being the largest economy in Latin America, piped water service coverage and sewage collection is not universal in Brazil. The relationship between access to water/sanitation and health was the objective of many studies recently. The majority of the existing work focuses on the impact of access to water and sewage, not investigating the effects of water quality and treatment. Moreover, the existing literature usually focuses on infant mortality and life expectancy indicators. Although these measures are important, they may not capture all the relevant public costs associated with health and related to hospitalizations. This paper aims at filling this gap by identifying the effects of sanitation policies on children morbidity rates by certain diseases in Brazilian municipalities.

This paper investigates the causal effect of education on earnings in Brazil by employing a new method proposed by Klein and Vella (2010) that obtains identification on the presence of conditional heteroskedasticity. In contrast to traditionally used IV methods, this approach yields unbiased estimates in the absence of instruments. Results indicate that the average return to education in Brazil was relatively stable at around 14% from 1995 to 2003, declined afterwards reaching 10.7% in 2014, but has bounced back to 11.8% after the economic crisis in 2015. The results suggest that the OLS estimations are downward biased and we interpret this as a sign of under-education premiums that are likely to occur in environments where the more talented ones are dropped from school and moved into the labor market earlier in life.

This paper employs a unified theoretical framework to estimate the effect of changes within China on the Brazilian and World's economy. Based on the Ricardian model of trade of Costinot et al. (2012), we perform counterfactuals exercises to analyze how industries in Brazil would have performed in the absence of the Chinese ascension. We discuss two main counterfactual exercises. First, we model productivity growth in China as the main lever by which Chinese supply and demand conditions evolve and affect economies worldwide. Second, we study how changes in composition of Chinese demand (taste) affects trade flows around the world. The two counterfactual exercises together suggest that changes in China's comparative advantage hampered manufacturing sectors abroad, in particular labor -intensive Brazilian manufacture producers. We find no support for the idea of a China taste shock driving demand towards raw materials. Our model suggests that if China triggered a commodity boom in the world, or at least in Brazil, this was driven mostly by increased income in China. And any changes in China's tastes over products contributed to moderate such boom. Specifically, our model indicates that the boom of soybeans cultivation in Brazil is due to changes in Brazilian comparative advantage paired with a level increase in demand for this product within China.

This article aims to introduce a methodological contribution to the wage decomposition, from the traditional decomposition of Oaxaca–Blinder. Specifically, we review the usual wage decomposition models and proposes a new technique that do not choose an advantage/disadvantage group in advance, a solution to the index problem, one of the most present criticisms in the decomposition salary of Oaxaca–Blinder. It is based on the analysis of the current wages of the analyzed groups, and not on the impacts of the income that the individuals should have, as usually appears in the models of decomposition. It applies the gender wage decomposition procedures in the Brazilian labor market, under the different approaches, from the microdata of the PNAD of 2015, which confirm the wage differences and discrimination between men and women. Finally, this article contributes to the decision on empirical strategies in the field of wage inequalities and, particularly, their interpretation.
