Monopoly power, trade protection and growth: cross industry evidence

This paper investigates the impact of monopoly power on trade policy. Annual panel-databases of Brazilian industries for the years 1988 through 1994 were used. The regressions reported here are robust to openness indicator, concentration index, control variables and sample size, and suggest that industries with higher monopoly power are more protected than competitive sectors. In the period of study the country experienced a major trade liberalization, but the results in the paper show that the reduction in protection was smaller in sectors with higher monopoly power. We thus have evidence favoring recent growth literature which stresses that interest groups with control over creasing productivity. The results here confirm the first part of this argument and show that organized groups in fact are able to obtain policy advantages that reduce competition.

Monopoly power and trade protection: cross- industry evidence

This paper investigates the impact of industry concentration on trade policy. Annual panel-databases of Brazilian industries for the years 1988 through 1994 were used. The regressions reported here are robust to openness indicator. concentration index, control variables and sample size, and suggest that the higher the concentration of a given industry the higher its leveI of trade protection. In the period of study the country experienced a major trade liberalization, but the results in the paper show that the reduction in protection was smaller in more concentrated sectors. Assuming that concentration is ;1 gCl()d proX\' for mOllopoh' po\\'er as it reduces the free-rider problem in coordinating a lobby the results in this paper indicates that interest groups with control over specific markets in fact are able to obtain policy advantages that reduce (international) competition.

Assessing competition in banking industry: a multiproduct approach

This paper aims to investigate the competition aspects of banking multiproduct operation. Based on an extension of Panzar and Rosse (1987)’s test to the case of a multiproduct banking firm, we take advantage of a new dataset constructed to Brazilian banking conglomerates to infer the impact of conglomeration on market power. We find that banks offering classic (i.e., loans and credit cards) and other bank products (i.e., brokerage services, insurance and capitalization bonds) have substantially higher market power than the ones which offer only classic products. Results suggest a positive bias on the traditional estimates of competition in which the multioutput actions are not taken into account.

Assessing competition in the banking industry: a multi-product approach

This paper investigates the competitive aspects of multi-product banking operations. Extending Panzar and Rosse (1987)’s model to the case of a multi-product banking firm, we show that the higher the economies of scope in multi-product banking are, the lower Panzar-Rosse’s measure of competition in the banking sector is. To test this empirical implication and determine the impact of multi-production/conglomeration on market power, we use a new dataset on Brazilian banking conglomerates. Consistent with our theoretical prediction, we find that banks offering classic banking products (i.e., loans and credit cards) and other banking products (i.e., brokerage services, insurance and capitalization bonds) have substantially higher market power than banks that offer only classic products. These results suggest a positive bias in the traditional estimates of competition in which multi-output actions are not considered.

Creating meanings, changing contexts: contested sustainability in the Brazilian beef industry

O objetivo desta pesquisa é compreender de que forma as organizações moldam seu ambiente, analisando por que algumas práticas tornam-se reconhecidas como ‘sustentáveis’ na indústria de carne bovina brasileira. O estudo dialoga com a literatura de institucionalismo organizacional ao apontar a necessidade de considerar a política (i.e. as negociações entre atores) e significados, a fim de entender como a estabilidade e a mudança institucional ocorrem em um contexto situado (i.e. em um tempo e espaço específicos). A pesquisa conclui que os entendimentos sobre o que poderia ser reconhecido como ‘sustentabilidade’ são o resultado de atores moldando o seu ambiente por meio de ações e interações que produzem significados. Seguindo uma abordagem de hegemonia, essas disputas não são apenas entre os atores que procuram vantagens recursivas, mas também procuram defender ou atacar as lógicas sociais que apoiam a posição dominante dos atores. Além disso, os atores exercem sua agência sobre as condições no presente (i.e. contexto situado), com base em um passado herdado e com o objetivo de produzir um futuro que eles imaginam. Para analisar tais processos uma abordagem de hegemonia entre atores e lógicas sociais foi desenvolvida para destacar a ordem de negociação, uma arena em que os atores lutam pela hegemonia. Como resultado de tais negociações, uma questão focal emerge, influenciando o discurso e interesses dos atores, bem como justificando as iniciativas, programas e tecnologias sobre tal questão; construindo, portanto, o consenso. Baseando-se em Realismo Crítico e Análise Crítica do Discurso, a pesquisa desenvolveu um estudo de caso longitudinal suportado por documentos públicos e confidenciais e entrevistas com especialistas, para examinar o caminho da sustentabilidade na indústria de carne bovina brasileira. Identificou-se três contextos diferentes para agência em relação à sustentabilidade. Enquanto no primeiro verifica-se um silêncio sobre práticas de sustentabilidade, o segundo enfatiza a emergência do desmatamento da Amazônia como uma questão focal, devido à agência do Greenpeace e MPF que força a indústria a desenvolver um sistema de monitoramento que rastreie seus fornecedores de gado de modo a evitar compra de suprimentos associadas ao desmatamento da Amazônia, dentre outras atividades ilegais. Finalmente, durante o terceiro contexto, o sistema de monitoramento permite que indústria de carne bovina se aproprie da sustentabilidade, assim o setor da carne passa a construir a sua legitimidade para influenciar sobre os riscos e oportunidades associadas ao contexto da sustentabilidade. Em termos de lógicas sociais, o desmatamento na Amazônia foi denunciado como um problema ambiental, nesta indústria, ancorado em algumas características da lógica do capitalismo, como a gestão de riscos, inovação e aumento da produtividade, cadeia de fornecimento global e governança. Embora este ataque questione a racionalidade da maximização racional lucro, impondo restrições ambientais para o comportamento das empresas, a solução desenvolvida é também ancorada sobre as mesmas características do capitalismo empregadas para atacá-lo. Como consequência, uma mudança gradual é ilustrada por uma transformação na ‘eficiência quantitativa’ do capitalismo, o aumento da produtividade devido à mudança da proporção de recursos consumidos para produção e à preocupação em evitar o desmatamento da Amazônia. No entanto, a ‘eficiência qualitativa’ do capitalismo é preservada uma vez que os grupos dominantes no poder ainda estão controlando os meios de produção e os recursos a eles associados (i.e. dinheiro, poder e legitimidade). Uma vez que estes processos de negociações são mediados pela racionalidade de se evitar risco aos negócios, consequentemente, a maximização do lucro, o núcleo duro da lógica do capitalismo é preservado. Portanto, os grupos dominantes mantêm sua hegemonia.

Inferring conduct under the threat of entry : the case of Brazilian cement industry

This paper demonstrates that when an industry faces potential entry and this threat of entry constrains pre-entry prices, cost and conduct are not identified from the comparative statics of equilibrium. In such a setting, the identifying assumption behind the well-established technique of relying on exogenous demand perturbations to empirically distinguish between alternative hypotheses of conduct is shown to fail. The Brazilian cement industry, where the threat of imports restrains market outcomes, provides an empirical illustration. In particular, pricecost margins estimated using this established technique are considerably biased downward, underestimating the degree of market power. A test of conduct is proposed, adapted to this constrained setting, which suggests that outcomes in the industry are collusive and characterised by market division.

Tail risk in the hedge fund industry

The dissertation goal is to quantify the tail risk premium embedded into hedge funds' returns. Tail risk is the probability of extreme large losses. Although it is a rare event, asset pricing theory suggests that investors demand compensation for holding assets sensitive to extreme market downturns. By de nition, such events have a small likelihood to be represented in the sample, what poses a challenge to estimate the e ects of tail risk by means of traditional approaches such as VaR. The results show that it is not su cient to account for the tail risk stemming from equities markets. Active portfolio management employed by hedge funds demand a speci c measure to estimate and control tail risk. Our proposed factor lls that void inasmuch it presents explanatory power both over the time series as well as the cross-section of funds' returns.

Capitalismo de estado e inovação: facetas da relação entre estado e iniciativa privada no desenvolvimento nacional

While countries managed to rapidly rise and recover economically, Brazilian social indicators have advanced at short pace in the last decades. Although millions of Brazilians have recently left poverty, Brazil still has a long way to go regarding its socioeconomic development. Circa one fifth of the population is still considered functionally illiterate, basic education has one of the poorest performances in the world, the country has no top-level universities nor produces technology or patents at relevant levels. This paper, at first, analyses how the interaction between government and private agents influenced Brazil’s industrial and economic development, identifying the existence of bonds based on the exchange of private interests that at great extension kept public policies from reaching goals of national interest – the so called crony capitalism. Secondly, the paper verifies how development policies based on the promotion of innovative companies and segments of the industry may positively impact broad socioeconomic development. The paper delves specifically into the cooperation between universities and industry as a development tool. Enterprises and universities, guided by their endogenous interests, may be combined for the structuring of a national innovation system. While universities are fundamentally interested in promoting knowledge accumulation, enterprises are willing to invest financial capital in universities in exchange for the economic exploitation of products developed within the academic environment and direct access to its human capital. Lastly, the paper identifies the legal and cultural barriers and advances of this mechanism in Brazil. It verifies that, notwithstanding the institutional advance promoted by the Law of Innovation to the university-enterprise cooperation in Brazil, the law wasn’t entirely capable of eliminating the legal uncertainty of this relationship and capturing in an efficient way the interests of the agents involved. Recently, federal law n. 12.863/2013 officially offered universities the option of bypassing problems related to public law by regulating support foundations, which conceives greater certainty and simplicity to the cooperation. There are, however, remaining uncertainties regarding the norms to be edited by the executive power, as well as conflicts of interest linked to the property rights over patents resulting from this kind of cooperation. The paper verifies, moreover, the existence of ideological resistance to this tool within universities, in such a way that it is unlikely that those relationships develop in a systematic way throughout the country without further engagement from the government and its executive and legislative bodies.

The consumer litigation industry: chasing dragon kings in lawyer-client networks

The community of lawyers and their clients form a scale-free bipartite network that develops naturally as the outcome of the recommendation process through which lawyers form their client base. This process is an example of preferential attachment where lawyers with more clients are more likely to be recommended to new clients. Consumer litigation is an important market for lawyers. In large consumer societies, there always a signi cant amount of consumption disputes that escalate to court. In this paper we analyze a dataset of thousands of lawsuits, reconstructing the lawyer-client network embedded in the data. Analyzing the degree distribution of this network we noticed that it follows that of a scale-free network built by preferential attachment, but for a few lawyers with much larger client base than could be expected by preferential attachment. Incidentally, most of these also gured on a list put together by the judiciary of Lawyers which openly advertised the bene ts of consumer litigation. According to the code of ethics of their profession, lawyers should not stimulate clients into litigation, but it is not strictly illegal. From a network formation point of view, this stimulation can be seen as a separate growth mechanism than preferential attachment alone. In this paper we nd that this composite growth can be detected by a simple statistical test, as simulations show that lawyers which use both mechanisms quickly become the \Dragon-Kings" of the distribution of the number of clients per lawyer.

Entry on the Brazilian renewable power market: a case study

Conferências internacionais sobre o clima, bem como crescente conscientização sobre as questões de sustentabilidade lançaram luz sobre o papel fundamental que as energias renováveis poderiam desempenhar na transição energética. Ao contrário de combustíveis fósseis, elas podem ser regeneradas em um curto período de tempo e, por conseguinte, espera-se que sejam uma parte da solução para reduzir o aquecimento global. O Brasil sempre teve um forte setor hidrelétrico, mas agora está na vanguarda em relação a todas as outras fontes de energias alternativas, como energia eólica, biomassa o energia solar. Estas indústrias são uma promessa para um futuro próspero, graças ao potencial natural do país, bem como uma legislação de apoio, e estão atraindo muitas empresas locais e internacionais. Este estudo tem como objetivo preencher uma lacuna na literatura analisando o exemplo de uma empresa estrangeira que entra no mercado da energia renovável no Brasil. Baseando-se na literatura como um fundo conceptual, um único estudo de caso têm sido realizados para delinear todos os aspectos do processo de entrada. Neste desenvolvimento, relações causais entre as orientações estratégicas e a evolução do negócio foram identificadas. Esta pesquisa traz uma contribuição para as discussões acadêmicas sobre as dinâmicas de entrada no setor de energia renovável através de evidências do mercado brasileiro.
