Environmental regulation, technology adoption and structural transformation: evidence from Brazilian sugarcane industry

We estimate the effects of the adoption of mechanized agriculture led by a new environmental regulation on structural change of local labor markets within a large emerging country, Brazil. In 2002, the state of S\~{a}o Paulo passed a law outlying the timeline to end sugarcane pre-harvest burning in the state. The environmental law led to the fast adoption of mechanized harvest. We investigate if the labor intensity of sugarcane production decreases; and, if so, if it leads to structural changes in the labor market. We use satellite data containing the type of sugarcane harvesting -- manual or mechanic harvest -- paired with official labor market data.%, also geomorphometric data base for our instrumental variable correction. We find suggestive evidence that mechanization of the field led to an increase in utilization of formal workers and a reduction in formal labor intensity in the sugarcane sector. This is partially compensated by an increase in the share of workers in other agricultural crops and in the construction and services sector. Although we find a reduction in employment in the manufacturing sector, the demand generated by the new agro-industries affected positively the all sectors via an increase in workers' wage.

How the full opening of the capital account to highly liquid financial markets led Latin America to two and a half cycles of ‘mania, panic and crash’

Latin America has recently experienced three cycles of capital inflows, the first two ending in major financial crises. The first took place between 1973 and the 1982 ‘debt-crisis’. The second took place between the 1989 ‘Brady bonds’ agreement (and the beginning of the economic reforms and financial liberalisation that followed) and the Argentinian 2001/2002 crisis, and ended up with four major crises (as well as the 1997 one in East Asia) — Mexico (1994), Brazil (1999), and two in Argentina (1995 and 2001/2). Finally, the third inflow-cycle began in 2003 as soon as international financial markets felt reassured by the surprisingly neo-liberal orientation of President Lula’s government; this cycle intensified in 2004 with the beginning of a (purely speculative) commodity price-boom, and actually strengthened after a brief interlude following the 2008 global financial crash — and at the time of writing (mid-2011) this cycle is still unfolding, although already showing considerable signs of distress. The main aim of this paper is to analyse the financial crises resulting from this second cycle (both in LA and in East Asia) from the perspective of Keynesian/ Minskyian/ Kindlebergian financial economics. I will attempt to show that no matter how diversely these newly financially liberalised Developing Countries tried to deal with the absorption problem created by the subsequent surges of inflow (and they did follow different routes), they invariably ended up in a major crisis. As a result (and despite the insistence of mainstream analysis), these financial crises took place mostly due to factors that were intrinsic (or inherent) to the workings of over-liquid and under-regulated financial markets — and as such, they were both fully deserved and fairly predictable. Furthermore, these crises point not just to major market failures, but to a systemic market failure: evidence suggests that these crises were the spontaneous outcome of actions by utility-maximising agents, freely operating in friendly (‘light-touch’) regulated, over-liquid financial markets. That is, these crises are clear examples that financial markets can be driven by buyers who take little notice of underlying values — i.e., by investors who have incentives to interpret information in a biased fashion in a systematic way. Thus, ‘fat tails’ also occurred because under these circumstances there is a high likelihood of self-made disastrous events. In other words, markets are not always right — indeed, in the case of financial markets they can be seriously wrong as a whole. Also, as the recent collapse of ‘MF Global’ indicates, the capacity of ‘utility-maximising’ agents operating in (excessively) ‘friendly-regulated’ and over-liquid financial market to learn from previous mistakes seems rather limited.

Debt composition and exchange rate balance sheet effects in Brazil: A firm level analysis

In this paper we study the interaction between macroeconomic environment and firms’ balance sheet effects in Brazil during the 1990’s. We start by assessing the influence of macroeconomic conditions on firms’ debt composition in Brazil. We found that larger firms tend to change debt currency composition more in response to a change in the exchange rate risk than small firms. We then proceed to investigate if and how exchange rate balance sheet effects affected the firms’ investment decisions. We test directly the exchange rate balance sheet effect on investment. Contrary to earlier findings (Bleakley and Cowan, 2002), we found that firms more indebted in foreign currency tend to invest less when there is an exchange rate devaluation. We tried different controls for the competitiveness effect. First, we control directly for the effect of the exchange rate on exports and imported inputs. We then pursue an alternative investigation strategy, inspired by the credit channel literature. According to this perspective, Tobin’s q can provide an adequate control for the competitiveness effect on investment. Our results provide supporting evidence for imperfect capital markets, and for a negative exchange rate balance sheet effect in Brazil. The results concerning the exchange rate balance sheet effect on investment are statistically significant and robust across the different specifications. We tested the results across different periods, classified according to the macroeconomic environment. Our findings suggest that the negative exchange rate balance sheet effect we found in the whole sample is due to the floating exchange rate period. We also found that exchange rate devaluations have important negative impact on both cash flows and sales of indebted firms. Furthermore, the impact of exchange rate variations is asymmetric, and the significant effect detected when no asymmetry is imposed is engendered by exchange rate devaluations.

Past and future of the bankruptcy law in Brazil and Latin America

This paper studies the Bankruptcy Law in Latin America, focusing on the Brazilian reform. We start with a review of the international literature and its evolution on this subject. Next, we examine the economic incentives associated with several aspects of bankruptcy laws and insolvency procedures in general, as well as the trade-offs involved. After this theoretical discussion, we evaluate empirically the current stage of the quality of insolvency procedures in Latin America using data from Doing Business and World Development Indicators, both from World Bank and International Financial Statistics from IMF. We find that the region is governed by an inefficient law, even when compared with regions of lower per capita income. As theoretical and econometric models predict, this inefficiency has severe consequences for credit markets and the cost of capital. Next, we focus on the recent Brazilian bankruptcy reform, analyzing its main changes and possible effects over the economic environment. The appendix describes difficulties of this process of reform in Brazil, and what other Latin American countries can possibly learn from it.

Speculative attacks on debts and optimum currency area: a welfare analysis

Traditionally the issue of an optimum currency area is based on the theoretical underpinnings developed in the 1960s by McKinnon [13], Kenen [12] and mainly Mundell [14], who is concerned with the benefits of lowering transaction costs vis-à- vis adjustments to asymmetrical shocks. Recently, this theme has been reappraised with new aspects included in the analysis, such as: incomplete markets, credibility of monetary policy and seigniorage, among others. For instance, Neumeyer [15] develops a general equilibrium model with incomplete asset markets and shows that a monetary union is desirable when the welfare gains of eliminating the exchange rate volatility are greater than the cost of reducing the number of currencies to hedge against risks. In this paper, we also resort to a general equilibrium model to evaluate financial aspects of an optimum currency area. Our focus is to appraise the welfare of a country heavily dependent on foreign capital that may suffer a speculative attack on its public debt. The welfare analysis uses as reference the self-fulfilling debt crisis model of Cole and Kehoe ([6], [7] and [8]), which is employed here to represent dollarization. Under this regime, the national government has no control over its monetary policy, the total public debt is denominated in dollars and it is in the hands of international bankers. To describe a country that is a member of a currency union, we modify the original Cole-Kehoe model by including public debt denominated in common currency, only purchased by national consumers. According to this rule, the member countries regain some influence over the monetary policy decision, which is, however, dependent on majority voting. We show that for specific levels of dollar debt, to create inflation tax on common-currency debt in order to avoid an external default is more desirable than to suspend its payment, which is the only choice available for a dollarized economy when foreign creditors decide not to renew their loans.

Implementação de sistemas de gestão integrados no setor de construção: estudo de casos brasileiros

As pressões de mercado, os programas de abertura financeira, a desregulamentação da atividade produtiva e a diminuição de barreiras protecionistas afetam significativamente a competitividade da indústria nacional. Outras mudanças, não apenas econômicas, mas sociais, políticas e tecnológicas, também pressionam as organizações a adotar novas estratégias empresariais e deixam claro que modelos de gestão tradicionais já não são mais suficientes para enfrentar estes novos desafios. Na busca de diferenciais competitivos, as empresas têm adotado sistemas de gestão da qualidade, de gestão ambiental e de gestão da saúde e segurança do trabalhador. Como forma de evidenciar a terceiros sua preocupação simultânea com estas três disciplinas, as empresas têm buscado a certificação integrada destes sistemas por meio das normas ISO 9001, ISO 14001 e OHSAS 18001. Surgem, assim, os Sistemas de Gestão Integrados (SGIs), objetos de pesquisa deste estudo. O recorte é setorial, sendo que o setor de construção foi escolhido devido a características como singularidade de seus produtos, alto impacto ambiental e alto índice de acidentes de trabalho. Com o objetivo de investigar como os SGIs foram implementados no setor de construção, foram escolhidos três casos de empresas sabidamente adotantes deste modelo de gestão. Foram analisadas as motivações, o processo de implementação e certificação do sistema, os fatores críticos de sucesso, as dificuldades encontradas e os benefícios colhidos com a adoção de SGIs. A pesquisa confirmou estudos anteriores que demonstram que a motivação, dependendo do contexto em que as empresas se inserem, pode ser por necessidade de maior competitividade, de legitimação, ou ainda, por responsabilidade ambiental de sua liderança. Os fatores críticos de sucesso são, dentre outros, comprometimento da alta administração, comunicação eficiente com as partes interessadas, disponibilidade de recursos e maturidade das equipes. As dificuldades encontradas foram a valorização excessiva de resultados econômico-financeiros, a complexidade do modelo adotado, a utilização burocrática do sistema, a falta de maturidade e preparo dos profissionais, o porte dos projetos, o perfil de competências dos profissionais e variados tipos de resistências. A adoção do SGI nas empresas estudadas esteve condicionada a situações do cenário econômico, do alto índice de terceirização verificado no setor e às dificuldades com a qualificação da mão-de-obra. Não obstante as dificuldades e os condicionantes, o SGI trouxe vários benefícios para as organizações e, um dado relevante, é que ele pode desencadear reações positivas ao longo da cadeia de valor, uma vez que as empresas adotantes de SGI passam a ser mais exigentes em relação a seus fornecedores.

Efeitos informais do salário mínimo e pobreza

Avaliamos a efetividade da política de salário mínimo nacional nos segmentos formais e informais do mercado de trabalho brasileiro. A nossa técnica consiste em mapear soluções de canto produzidas pela política de salário mínimo que são posteriormente utilizados como mecanismo de focalização na simulação de limites superiores dos efeitos de reajustes do salário mínimo sobre medidas de pobreza no Brasil. Destacamos dois “efeitos informais” do mínimo: i) a alta porcentagem de trabalhadores sem carteira assinada ganhando exatamente um mínimo, o que potencializa os efeitos aliviadores de pobreza do salário mínimo; e ii) A observação de remunerações que utilizam o salário mínimo, como numerário, em particular no setor formal.

Decent work and the informal sector in Brazil

Brazil has a substantial share – about 60% by some measures - of its employees working without labor registry and 62% of its private sector workers not contributing to social security. Informality is important because its job precaurioness, social desprotection consequences, and it is also very correlated with poverty and other social welfare concepts measured at a family level. 58% of the country population that is found below the indigent line live in families headed by informal workers. The complexity of the informal sector is derived from the multiple relevant dimensions of jobs quality. The basis used for guiding policy interventions depends on which effect of informality one is interested such: as lowering job precaurioness, increasing occupational risks, increasing the degree of protection against adverse shocks, allowing that good oportunities to be taken by the credit provision, improving informal workers families living conditions, implementing afirmative actions, reducing tax evasion etc. This report gauges various aspects of the informal sector activities in Brazil over the last decades. Our artistic constraint are the available sources of information. The final purpose is to help the design of policies aimed to assist those that hold “indecent” jobs

Brazil: the pressure points in labor legislation

Brazil’s experience shows that the economic and political history of a country is a critical determinant of which labor laws influence wages and employment, and which are not binding. Long periods of high inflation, illiteracy of the workforce, and biases in the design and enforcement of labor legislation bred by the country’s socioeconomic history are all important in determining the reach of labor laws. Defying conventional wisdom, these factors are shown to affect labor market outcomes even in the sector of employment regarded as unregulated. Following accepted practice in Brazil, we distinguish regulated from unregulated employment by determining whether or not the contract has been ratified by the Ministry of Labor, viz., groups of workers with and without signed work booklet. We then examine the degree of adherence to labor laws in the formal and informal sectors, and finds “pressure points” – viz., evidence of the law on minimum wage, work-hours, and payment timing being binding on outcomes – in both the formal and informal sectors of the Brazilian labor market. The findings of the paper imply that in terms of the design of legislation, informality in Brazil is mainly a fiscal, and not a legal phenomenon. But the manner in which these laws have been enforced is also critical determinant of informality in Brazil: poor record-keeping has strengthened the incentives to stay informal that are already built into the design of the main social security programs, and ambiguities in the design of labor legislation combined with slanted enforcement by labor courts have led to workers effectively being accorded the same labor rights whether or not they have ratified contracts. The incentives to stay informal are naturally higher for workers who are assured of protection under labor legislation regardless of the nature of their contract, which only alters their financial relationship with the government. The paper concludes that informality in Brazil will remain high as long as labor laws remain ambiguous and enforced with a clear pro-labor bias, and social security programs lack tight benefitcontribution linkages and strong enforcement mechanisms.

Trade barriers and productivity growth: cross-industry evidence

This article investigates the impact of trade protection on the evolution of labor productivity and total factor productivity (TFP) of the Brazilian manufacturing sector. An annual panel-dataset of 16 industries for the years 1985 through 1997, a period that includes a major trade liberalization, was used. The regressions reported here are robust to openness indicator (nominal tari®s and e®ective protection rate were used), control variables and time period and suggest that barriers to trade negatively a®ects productivity growth at industry level: those sectors with lower barriers experienced higher growth. We were also able to link the observed increase of industry productivity growth after 1991 to the widespread reduction on exective protection experienced in the country in the nineties.

Índice de governança corporativa : variação das empresas brasileiras em função das expectativas de mercado

Os conceitos de Governança Corporativa não são novos, mas a gravidade de impactos financeiros gerados por escândalos corporativos estimula as empresas a adotarem melhores níveis de governança. Investidores profissionais se dispõem a pagar um ágio para investir em empresas com altos padrões de governança e que garantam um ambiente corporativo favorável ao retorno do seu investimento. A liquidez na qual o mundo viveu nos últimos anos propiciou um volume cada vez maior de recursos; não apenas para o Brasil, mas para grande parte dos mercados emergentes; para os mercados de capitais locais e em investimentos diretos. Esse capital, em grande parte externo, necessita de transparência, regulamentação e outros requerimentos de modo a reduzir os riscos relacionados às empresas alvo. Com base nas expectativas de mercado de indicadores macroeconômicos disponibilizadas pelo Sistema de Expectativas de Mercado do Banco Central do Brasil e nas informações fornecidas pela Bovespa e seus índices de mercado Ibovespa e IGC, este trabalho buscou uma associação entre variações nestas expectativas e valorização ou desvalorização da média de capitalização bursátil e índice de bolsa - Ibovespa e IGC. Observou-se que tanto o Ibovespa quanto o IGC e a média de capitalização bursátil da Bovespa e Ibovespa estão sujeitos as mesmas influências de variáveis macroeconômicas nacionais, mas em magnitudes diferentes. Entretanto, fez-se como exceção a média de capitalização bursátil do IGC, que sofreu influência de expectativas macroeconômicas diferentes dos demais. 6

O planejamento estratégico do capital humano como fator de desenvolvimento sustentável das organizações na agroenergia: estudo de caso

O objetivo desta tese é analisar, orientar e indicar algumas formas de mensuração de resultados das ações ou programas na área de Gestão de Pessoas ao longo dos anos, bem como de novas tendências no setor de agroenergia. O trabalho procura também propor práticas de planejamento estratégico e, indicadores para as organizações com foco no desenvolvimento e nas mudanças previstas nas organizações, no mercado de trabalho, nos modelos de gestão e de negócios do segmento de produção de cana-de-açúcar para os próximos anos. No estudo são analisados as transformações organizacionais, novos desafios competitivos do presente e do futuro, e a forma como a área de Recursos Humanos nas diversas organizações do setor, tem acompanhado tal processo, verificando o impacto dessas ações em um contexto de mudanças nos processos da cadeia agrícola (mecanização do plantio, colheita,.dentre outros), da cadeia industrial (biorefinarias, etanol de segunda geração, gaseificação...dentre outros), e no desenvolvimento organizacional e humano como parte integrante de um programa de sustentabilidade das organizações. São abordados metodologias, sistemas e ferramentas de planejamento estratégico, e mensuração propostas por certos autores que visam a demonstrar o impacto das estratégias e as ações na Gestão de Pessoas em direção ao cumprimento das metas e objetivos das organizações, em um cenário de forte crescimento interno e global do mercado de bioenergia. Nesse cenário, expõe-se e discute-se como as empresas do setor sucroalcooleiro utilizam, na prática, essas metodologias e os indicadores de performance da área frente às necessidades, e indicam-se as melhores práticas e ferramentas que visam a facilitar os processos decisórios, o uso de métricas de Recursos Humanos para previsão e acompanhamento do Capital Humano, e a otimização dos recursos e dos investimentos frente aos novos desafios do setor. Embora já se notem várias iniciativas visando a tornar a Gestão de Pessoas um fator estratégico para as organizações da agroenergia, a pesquisa identificou que a área de Recursos Humanos está evoluindo nessa direção e pode contribuir de forma efetiva para a melhor performance e sustentabilidade dos negócios.

Structural Transformation and Productivity in Latin America

We investigate the role of sectorial differences in labor productivity and the process of structural transformation (reallocation of labor across sectors) in accounting for the time path of aggregate productivity across six Latin American countries (Brazil, Chile, Argentina, Colombia, Mexico and Venezuela) from 1950 to 2003. We used a general equilibrium model with three sectors (agriculture, industry and services) calibrated to those six economies. The model is used to compare the trajectory of productivity in each sector of activity with that of the United States and it impact on aggregate productivity.While in Brazil and Argentina, the Service Sector was responsible for reversing the process of catch up in productivity that occurred until the 1980s, in others, like Colombia, Mexico and Venezuela, low productivity growth of the three sectors explain their poor performance.

Essays in macroeconomics and public finance

Esta tese dedica-se ao estudo dos sistemas tributários. Eu investigo como um sistema tributário afeta as escolhas dos indivíduos e consequentemente os recursos do país. Eu mostro como um sistema tributário induz as escolhas das pessoas, determinado assim as alocações de trabalho, produto e consumo da economia. No primeiro e segundo capítulo eu examino a taxação sobre os indivíduos, enquanto que no terceiro e quarto capítulos analiso a incidîncia tributária sobre os diferentes agentes da sociedade. No capítulo um, eu examino o sistema tributário ótimo, seguindo Mirrlees (1971) e Saez (2001). Eu mostro como seria este sistema tributário no Brasil, país com profunda desigualdade de renda entre os indivíduos. Ademais, eu investigo o sistema tributário afim, considerado uma alternativa entre os sistemas atual e o ótimo. No segundo capítulo eu analiso o sistema tributário conhecido como sacríficio igual. Mostro como o sistema tribuária derivado por Young (1987), redesenhado por Berliant and Gouveia (1993), se comporta no teste de eficiência derivado por Werning (2007). No terceiro e quarto capítulo eu examino como propostas de reforma tribuária afetariam a economia brasileira. No capítulo três investigo como uma reforma tributária atingiria as diferentes classes socias. No capítulo quatro, eu estudo as melhores direções para uma reforma tributária no Brasil, mostrando qual arranjo de impostos é menos ineficiente para o país. Por fim, investigo os efeitos de duas propostas de reforma tributária sobre a economia brasileira. Explicito quais os ganhos de produto e bem estar de cada proposta. Dedico especial atenção aos ganhos/perdas de curto prazo, pois estes podem inviabilizar uma reforma tributária, mesmo esta gerando ganhos de longo prazo.
