Drought can have large, negative impacts on livelihoods and development outcomes in low- and middle-income countries. This highlights the need for drought response policies that can mitigate these impacts. We evaluate the policy response to the 2014–15 drought in Brazil that reduced the supply of water to the largest city in South America, São Paulo, by approximately one-third. Using microdata on household water consumption and a difference-in-difference design, we find that a penalty-based instrument induced household conservation behaviour but that a reward-based instrument did not. We examine why the reward-based instrument, which was both ineffective and expensive, was implemented at all. Our suggested explanation lies in political budget cycle theory. Exploratory tests imply that the reward-based instrument increased the share of votes to the incumbent governor. Penalty-based instruments are the technically effective drought response, but water sector decision makers in developing countries may need to contend with the distortionary effect of electoral cycles to implement them.

This paper uses a dataset from one of the largest credit card issuers in Brazil to investigate the extent of credit constraints for one of the world's largest emerging market economies. In order to deal with the endogeneity problem from an observational dataset, an identification strategy based on the issuer actual policies was used to better identify the long run effects of a credit card limit increase on debt. The results point to a long run effect of credit limit on credit card debts of 0.1144, a similar size to the ones found in Gross and Souleles (2001). This value indicates the Permanent Income Hypothesis is rejected for this sample, and some evidence supporting a variation of buffer stock behavior is found. Furthermore, results indicate the degree of heterogeneity in effects is much higher than similar results for developed countries, lending credence to the conclusion credit constraints are much stronger for lower income groups. This conclusion is in line to previous studies in Brazil, such as de Lucinda and Vieira (2014).

We examine the effects of a large temporary energy-savings program on the valuation of energy efficiency by Brazilian households, as well as its counterfactual energy savings. Using a representative sample of Brazilian households, we specify and estimate a structural model of appliance choice and document that (i) the program only increases the valuations of households facing incentives in the form of an energy consumption quota introduced by the program; (ii) the effect of incentives dominates other components of the energy efficiency gap; (iii) the effect of the program on valuations is temporary, with these essentially reverting to prior levels after the end of the program; (iv) heterogeneity in valuations is prevalent; (v) focusing only on the purchase of new refrigerators, the counterfactual energy savings are non-trivial, being equivalent to the yearly electricity consumption of a city with 1.15 mn inhabitants. The findings suggest that short-lived reactions to temporary programs on the extensive margin are non-trivial and have log-run implications via the purchase of durables.

Switching costs are a leading cause of customer lock-in in banking, reducing the extent of competition and increasing market power in this industry. This paper tries to estimate these costs using a methodology that does not require customer microdata. The estimates obtained here—using bank accounting information collected on a quarterly basis from 2009 to 2011—indicate substantial switching costs in the deposit market, and such costs tend to be lower for customers of larger banks. Additionally, there is some evidence that much of a bank's market share is due to its continued relationships with customers over time (a lock-in effect). Thus, the extent of potential competition in Brazilian banking could be severely limited by these costs. Custos de mudança são uma das principais causas de retenção de clientes na indústria bancária, reduzindo a competição e aumentando o poder de mercado nesta indústria. Este artigo tenta mensurar tais custos usando uma metodologia que não necessita o uso de microdados. As estimativas obtidas aqui - utilizando informações contábeis dos bancos em uma base trimestral entre 2009 e 2011 - indicam custos de mudança substanciais no mercado de depósitos à vista, e tais custos tendem a ser menores para clientes de bancos maiores. Além disso, existe alguma evidência que a maior parte da participação de mercado de um banco é devido às suas relações com os consumidores ao longo do tempo (efeito lock-in). Portanto, a extensão da competição potencial na indústria bancária brasileira pode ser fortemente limitada por tais custos.

O sucesso na aplicacao da lei de defesa da concorrencia no que diz respeito a punicao de carteis depende de procedimentos solidos de investigacao e punicao eficaz. No entanto, a legislacao existente apenas fornece direcao para o calculo das multas de cartel com base na receita de vendas, ainda que tais multas nao possam ser inferiores ao ganho de cartel. Usando dados de um caso real, temos dois objetivos no presente artigo: (i) revisar os desafios associados com o calculo de estimativas de sobrepreco de cartel e (ii) investigar se as multas aplicadas a firma estavam de acordo com o valor do sobrepreco de cartel. Utilizamos tres metodologias para estimar estes sobreprecos. Os resultados indicam que as estimativas sao sensiveis as hipoteses utilizadas, mas exceto por modelos diferencas em diferencas com tendencias quadraticas ou cubicas, as multas estao aproximadamente no ponto medio das estimativas. Isso indica que as multas estao em linha com os sobreprecos de cartel, mas se recomenda o uso de um conjunto de estimativas produzidas por diferentes metodos para se ter maior seguranca de sua adequacao.

The PBE program made the adoption of energy labels mandatory in the Brazilian refrigerator market. In this paper, we examine the effects of PBE using data from a nationally representative sample of households and a structural model of appliance choice. We document a modest increase in the valuation of energy costs by Brazilian consumers. However, the program is unable to eliminate the energy efficiency gap, in that consumers undervalue energy costs both pre-and post-PBE. Moreover, our policy simulation documents little product switching and heterogeneity in responses. All in all, while the PBE program aimed to both reduce energy consumption and increase energy efficiency, we can only claim robust evidence of the latter.

A existência de custos de procura é um fenômeno muito comum e pouco estudado no Brasil. O presente estudo busca avaliar a importância dos custos de procura na dispersão de preços de gasolina e de etanol no município de São Paulo. Para tanto, são utilizados como referenciais teóricos modelos de dispersão e estudos de estruturas de mercado. A parte empírica contempla duas etapas, na primeira é estimado qual o mercado relevante para o varejo de combustíveis e na segunda é descrita a dispersão na área. Os dados dos preços de varejo são coletados semanalmente e a série histórica foi cedida pela Agência Nacional do Petróleo, Gás Natural e Biocombustíveis. Os resultados das estimações mostram que, apesar da dispersão, possivelmente a competição local é mais relevante para o entendimento da dispersão de preços do que os custos de procura.

Summary This paper utilizes Brazilian data to investigate interest-rate sensitivity and informational issues associated with the credit demand of the middle-income class in a large emerging economy. This study’s data were collected from an experiment in which credit offers with randomized interest rates were sent to recipients. The results indicate that credit constraints and informational issues are important for both the lower middle-class and higher middle-class income groups. Interest rate reductions may be more effective for higher income groups.

O uso de medidas de produtividade na avaliação de políticas públicas baseadas na suposição de concorrência perfeita pode levar a conclusões incorretas sobre a sua eficácia. Nesse sentido, o presente estudo busca analisar quão distante da competição perfeita a indústria de transformação brasileira se encontra. Os resultados apontam que, em média, o preço é 2,41 vezes o custo marginal, rejeitando a validade da hipótese de concorrência perfeita e indicando que análises que não levam em conta tal padrão de competição geram conclusões errôneas. Os setores florestal e metalúrgico apresentaram os maiores mark ups (3,81 e 2,95 respectivamente), sendo tal conclusão robusta a retornos de escala e formas alternativas de mensuração. The use of productivity measures based on the assumption of perfect competition to evaluate public policies can lead to incorrect conclusions about them. In this sense, the present research aims to analyze how far from perfect competition the Brazilian industry is. The results indicated that the prices are, in general, 2.41 times marginal cost, which shows that the perfect competition hypothesis is not valid for the Brazilian industry and indicate that not considering the competition pattern lead to incorrect conclusions. The forest and metallurgy sectors had the highest mark ups (3.81 and 2.95 respectively), and these results are robust to assumptions about scale economies and different measures of mark up.

The aim of this paper is to analyze the determining factors for the pricing of handsets sold with service plans, using the hedonic price method. This was undertaken by building a database comprising 48 handset models, under nine different service plans, over a period of 53 weeks in 2008, and resulted in 27 different attributes and a total number of nearly 300,000 data registers. The results suggest that the value of monthly subscriptions and calling minutes are important to explain the prices of handsets. Furthermore, both the physical volume and number of megapixels of a camera had an effect on the prices. The bigger the handset, the cheaper it becomes, and the more megapixels a camera phone has, the more expensive it becomes. Additionally, it was found that in 2008 Brazilian phone companies were subsidizing enabled data connection handsets. O objetivo deste artigo é analisar os determinantes dos preços dos aparelhos celulares vendidos com planos de serviço, usando a metodologia de preços hedônicos. Neste sentido, foi construída uma base de dados compreendendo 48 modelos de aparelhos, em nove categorias de planos de serviço, durante 53 semanas em 2008, com 27 atributos diferentes totalizando quase 300,000 registros de dados. Os resultados indicam que o valor da assinatura mensal e dos minutos de chamadas são importantes para explicar os preços do aparelho. Além do mais tanto o volume físico quanto o número de megapixels de uma câmera possuem efeitos sobre os preços. Quanto maior o aparelho, mais barato ele é, e quantos mais megapixels a câmera possui, mais caro o aparelho se torna. Outra verificação encontrada é que em 2008 as operadoras brasileiras subsidiaram celulares habilitados com conexão de dados.

Neste artigo analisamos como uma redução nos custos de mudança afeta os mercados em que existem externalidades de rede. Para isto, utilizamos o exemplo da introdução da portabilidade numérica no Brasil. Inicialmente foram revisitadas as principais correntes da literatura, e na parte empírica foi construída uma base de dados por Área de Numeração, durante três anos. Os resultados do modelo econométrico apontam para uma convergência nas participações de mercado, sendo menor onde há maior disparidade entre as participações de mercado. A redução nos custos de mudança com a portabilidade numérica, neste caso, apenas agiu no sentido de acentuar estas tendências.

he aim of this paper is to provide insights on the determinants of the indebtedness of Brazilian companies. Initially, this paper replicates the main empirical tests on the literature. The reduced explanatory power of the results led us to propose a new methodology using the GMM method of Blundell and Bond (1998), which points out companies with higher roportions of fixed assets on total assets present higher indebtedness. Our results indicate that estimation of the equations implied by the target leverage model tends to generate seriously biased estimates if the endogeneity of the covariates is not explicitly considered in the analysis.

According to the World Health Organization, the obesity epidemic is a threat. Brazil is not an exception, and the objective of this article is to analyze the effects of a "fat tax" there. For this purpose, the estimation of a demand system was carried out and policy simulations were performed using the estimated parameters. The simulation results indicate that to be successful, this "fat tax" must be combined with a subsidy on healthy food. Another contribution was the analysis of a linear symmetric revenue-neutral tax schedule with more pronounced changes to micronutrient intake at no net cost to the government.

Authoritarian governments and exchange rate policy in Latin American countries. Our aim on this paper is to identify the exchange rate policies used by Authoritarian governments in Latin America during the 170’s and 180’s. The literature shows that the focus of the exchange rate policy was on inflation control, which was not consistent with the evidence. We show on this paper that these governments aimed at a undervalued currency because of the behavior of the external balance of the countries.

A recente crise de abastecimento em Sao Paulo mostrou a importância da regulacao no setor de saneamento no Estado de Sao Paulo. Neste sentido, o presente artigo busca auxiliar o desenho de regulacao no sentido de verificar a existencia de economias de escala e de escopo no setor de saneamento em Sao Paulo. Para tanto, foi construida uma base de dados a partir de dados internos da SABESP, combinados com dados operacionais extraidos do SNIS. Com esta base de dados foi utilizada a metodologia de Evans e Heckman, para a avaliacao de economias de escala e de escopo. Os resultados nos permitem concluir que a existencia de deseconomias de escala e algo extremamente raro nas cidades atendidas pela SABESP, sendo que quase todas apresentam valores negativos para a estatistica SC -- o que indica que o custo de producao dos servicos de agua e esgoto, nos niveis observados, e mais economicamente oferecido no âmbito de uma empresa do que em duas empresas separadas. No entanto, as evidencias sao mais fracas com relacao as economias de escopo. Mas mesmo assim, na grande maioria das cidades atendidas pela SABESP, e mais barato o fornecimento dos servicos de agua e esgoto conjuntamente dentro de uma empresa do que a separacao em duas empresas focadas em diferentes servicos. Tendo em vista os resultados, podemos concluir que iniciativas que visem a separacao estrutural de operadoras de agua integradas tendem a gerar ineficiencias do lado produtivo, fazendo com que o fornecimento dos servicos seja menos economico.

We quantify the effects of the Swedish GCR, a program to reduce oil dependence and greenhouse gas emissions in the automobile industry. We find the GCR to increase the market shares of `green cars' and its cost to be $109/tonCO2 saved, thus 5 times the price of an emission permit. Since the main green cars in Sweden are FFVs (flexible-fuel vehicles), which can switch between petrol (gasoline) and ethanol, we also account for fuel choice, which increases the cost of the program. Finally, we show that consumers would have purchased FFVs regardless of the rebate provided by the GCR.

This paper aims to investigate the existence of persistence in superior performance in Brazilian stock market funds from 2001 to 2014. In order to do so, we used a sample free of survivorship bias and four different market models to characterize the expected return and risk relationship. In all models we were not able to find evidence consistent with superior performance, indicating performance differences could be more attributed to different exposures to risk factors than superior skill. Some additional evidence was found the momentum factor seems to explain a large part of the funds’ excess returns in both top and bottom deciles.

The aim of this paper is to review some of the existing tests for competition in Brazilian banking, as well as to propose an alternative. After the description of the institutional setting of the Brazilian Banking system on this period, the competition tests on the literature were reviewed, beginning with the test proposed by Panzar and Rosse (1987). The market does not seem to be in long-run equilibrium, implying only the market does not seem to find itself in collusive outcome. The next step was to try a new methodology, applied by Moreno, Martínez and Ruiz (2006) for the Spanish banking market. On this methodology, in which the assumption of equality of conduct parameters between firms and time periods is relaxed, the results indicate that, for some firms and in some time periods, a cooperative conduct in fact is present. Neste artigo, o objetivo é rever os testes empíricos existentes para o grau de competição no setor bancário brasileiro, assim como propor algumas alternativas. Após a descrição do ambiente institucional do sistema bancário brasileiro, os testes sobre a competição, presentes na literatura, foram revisados, começando com o proposto por Panzar e Rosse (1987). A principal conclusão que pode ser extraída desta análise é que o mercado não aparenta estar em equilíbrio de longo prazo, indicando que o mercado não é regido por condições de colusão perfeita. O passo seguinte foi tentar uma nova metodolodia aplicada por Moreno, Martínez e Ruiz (2006) para o mercado bancário espanhol. Nesta metodologia, em que a hipótese de igualdade dos parâmetros de conduta entre empresas e ao longo do tempo é relaxada, os resultados indicam que, para algumas empresas e em alguns instantes do tempo, uma conduta coo-perativa está presente.

O presente artigo busca investigar a relação entre as características institucionais do mercado de crédito de um país e a sua especialização no comércio de manufaturas. Para tanto, inicialmente começamos modelando esta relação. A análise empírica, envolvendo dados setoriais da indústria brasileira para o período entre 1996 e 2000, permitiu observar uma relação entre a demanda por fundos externos e grau de especialização em produtos manufaturados, de acordo com o desenvolvimento teórico. Esta relação se manteve mesmo com a realização de uma análise econométrica adicional, que tinha o objetivo de controlar os vieses de simultaneidade e causalidade reversaThis paper aims to investigate the existence of a relationship between the institutional characteristics of the credit market of a country and its degree of specialization on trade of manufactures. In order to do so, we started by formally modeling this relationship. The empirical analysis, with Brazilian sectoral data for the period between 1996 and 2000, we could observe a relationship between the demand for external financing and the degree of specialization in industrial products, in accordance to the theoretical development. This relationship holds even after our robustness tests, using instrumental variables, aimed at dealing with the problems of simultaneity and reverse causality.

Neste artigo são simuladas as implicações concorrenciais decorrentes da compra do controle da empresa COPENE pelo grupo BRASKEM. Mais especificamente, tal operação diz respeito aos efeitos da concentração horizontal no mercado de polietilenos (PEAD, PEBD e PEBDL), e da integração vertical no mercado de eteno. Para avaliar os efeitos da operação, foi realizada uma análise que simulou o comportamento das empresas produtoras de polietilenos e eteno em termos de fixação de preços e quantidades ofertadas. As principais conclusões destas simulações, partindo da formação da empresa BRASKEM, são: (i) elevação do preço médio dos polietilenos no mercado brasileiro; (ii) redução da quantidade total de polietilenos consumida; (iii) elevação da concentração no setor, medida pelo Índice Herfindahl-Hirschmann; (iv) maior participação de mercado da empresa BRASKEM, o que reforça sua posição dominante.In this paper, we aim to analyze the consequences for the competition as regards the purchase of control of COPENE enterprise by the BRASKEM group. Specifically, such operation increases the degree of horizontal concentration in Brazilian Polyethylene market (PEAD, PEBD, PEBDL), as well as the concentration in the market for ethene. In order to evaluate the consequences of these operations, an analysis was carried out in order to simulate the behavior of producing companies of polyethylene and ethene as regards prices and quantities. The main conclusions of these simulations, from the formation of BRASKEM enterprise: (i) increase in average prices of polyethylene in Brazilian Market; (ii) decrease in the total quantity of polyethylene consumed; (iii) Increase in the Herfindahl-Hirschman Index in the sector; (iv) greater market share of BRASKEM, reinforcing its dominant position.

O controle da oferta de moeda foi um dos principais instrumentos na execução da política monetária desenhada pelos gestores do PAEG (1964/66). Embora a inflação tenha sido controlada, as metas previstas de execução monetária não foram alçadas. Pastore (1973, 1973a), Lara Resende (1982) e Cysne (1993) discordam, ora dos motivos, ora do momento em que os fatos ocorreram. Com a técnica de séries de tempo foi possível investigar o que de fato ocorreu. Como resultado desta investigação, durante o PAEG: a) apenas uma mudança importante ocorreu na oferta de moeda (julho de 1965). Se outras mudanças ocorreram, elas foram antes ou depois do plano; b) apesar dos autores concordarem com o papel do financiamento monetário do Caixa do Tesouro, o crédito concedido pelo Banco do Brasil enquanto Autoridade Monetária é o maior candidato para explicar o descontrole da oferta de moeda durante o plano; c) o crédito dado pelos Bancos Comerciais ao setor privado não teve qualquer papel no descontrole da oferta de moeda durante o plano e d) o papel das reservas internacionais descrito pelos autores não foi o que de fato ocorreu. A utilização de dados de reservas que não aqueles disponibilizados pela SUMOC em termos reais impossibilitou um trabalho mais adequado por parte dos autores.The control of the money supply was one of the most important instruments used in the carrying out of the monetary policy designed by the author of PAEG (1964/1966). Although the inflation has been controlled, the targets for monetary supply have not been reached. Pastore (1973, 1973a), Lara Resente (1982) and Cysne (1993) disaggee both on the reasons for that and the timing of the relevant facts. With a Time Series analysis it was possible to investigate what really happened with the money supply. The main conclusions are: a) During the PAEG, only one important structural change had happened (July 1965); other breaks have happened before the plan; b) although all of these authors agree with the role played by the money financing of Treasury, the credit supplied by Banco do Brasil as Monetary Authority is the best candidate in explaining the behavior of the Money Supply during the plan; c) the credit supplied by the Commercial Banks to the private sector had not any role in the determination of money supply during the period and d) the role of international reserves described by the authors is different from what really happened. The use of data on reserves other than those made available by SUMOC in real terms turned impossible a more precise work by these authors.

In this paper we proposed an econometric model for industrial electricity demand in Brazil. Differently from residential customers, industries in Brazil, in addition to purchasing energy and capacity, also face a tariff menu with Time of Use pricing. Each item in this menu also has different components and price discrimination structure. All these characteristics pose an empirical problem that, so far, has not been faced together in the literature. This methodology was applied in a non-experimental micro data sample of 646 large Brazilian industrial customers (with demands over 300 KW) between January 2002 and December 2006. The results indicate demands for the various services (capacity and energy, separated between peak and non-peak hours) are price elastic, and at least in the AZUL tariff, there is complementarity between energy and capacity in the different periods. Thus, policies on tariff structures based on assumptions of an inelastic aggregate electricity demand could have effects that are quite different from what was intended.

In this paper, an estimation of a Spatial Covariance Function was proposed for determining the relevant geographic market for a merger. This methodology was applied to a proposed merger between two competing Brazilian supermarket chains. During this application, the shortcomings of the analysis carried out by the Brazilian Antitrust System were initially pointed out, including the geographic dimension of the relevant market, which was found to be separated in each municipality located on the shore of Sao Paulo state. The results, based on the estimated spatial covariance function using price data on 22 products in 43 supermarkets, indicate a single geographic market for all municipalities
