How to indirectly assess transaction costs to evaluate market integration: evidence from the international ethanol market

Mercados são instituições criadas para facilitar uma atividade de comercialização. Isto é possível porque um mercado é constituído por instituições que foram desenhadas para reduzir os custos de transação associados a este processo de troca. A partir dessas duas ideias, esta tese possui três objetivos principais. (i) Analisar por que a literatura de análise de cointegração tem mensurado estes custos de forma imprecisa. A principal razão é certa confusão entre os conceitos de custos de transação, de transporte e de comercialização. (ii) Propor um procedimento para mensurar indiretamente os custos de transação de mercado variáveis combinando os modelos de cointegração com mudança de regime e a estrutura teórica oferecidas pela Nova Economia Institucional. Este procedimento é aplicado para quantificar quanto custa comercializar etanol no mercado internacional usando suas atuais instituições. (iii) Por fim, usando os mesmos modelos e a mesma estrutura teórica, esta dissertação contesta a hipótese de que já existe um mercado internacional de etanol bem desenvolvido, tal qual a literatura tem assumido. De forma semelhante, também é avaliada a hipótese de que a remoção das barreiras comerciais norte-americanas para o etanol brasileiro seria uma condição suficiente para o desenvolvimento deste mercado internacional. Os testes aplicados rejeitam ambas as hipóteses.

Allocation of authority in franchise chains

This article investigates the level of delegation in franchise chains, distinguishing the two most relevant franchising models: Business Format Franchising and Learning Network Franchising. The two models basically differ on the level of real authority (effective control over decisions) exercised by the franchisors. Differences in business features, such as the required standardization, monitoring costs and consumer sensitivity to variations in product attributes (consumer measurement costs), explain the adoption of the different models of franchising. These variables affect the trade-off between the risk of brand name loss and the gains in knowledge sharing and learning within the network. The higher the need for standardization, the higher is the risk of brand name loss, and, consequently, the more likely the franchisor will adopt an organizational design that confers more control over franchisees’ decisions, such as business format franchising. This paper presents two case studies with Brazilian food franchise chains that illustrate the main argument and suggest additional propositions. Moreover, an empirical analysis of 223 franchise chains provides additional support to the hypothesis of a negative the effect of required standardization on the level of delegation.

The firm size wage premium : a quantile analysis

Empirical evidence shows that larger firms pay higher wages than smaller ones. This wage premium is called the firm size wage effect. The firm size effect on wages may be attributed to many factors, as differentials on productivity, efficiency wage, to prevent union formation, or rent sharing. The present study uses quantile regression to investigate the finn size wage effect. By offering insight into who benefits from the wage premi um, quantile regression helps eliminate and refine possible explanations. Estimated results are consistent with the hypothesis that the higher wages paid by large firms can be explained by the difference in monitoring costs that large firms face. Results also suggest that more highly skilled workers are more often found at larger firms .

Informational spillovers in the pre-1914 London sovereign debt market

We document a novel type of international financial contagion whose driving force is shared financial intermediation. In the London peripheral sovereign debt market during pre-1914 period financial intermediation played a major informational role to investors, most likely because of the absence of international monitoring agencies and the substantial agency costs. Using two events of financial distress – the Brazilian Funding Loan of 1898 and the Greek Funding Loan of 1893 – as quasi-natural experiments, we document that, following the crises, the bond prices of countries with no meaningful economic links to the distressed countries, but shared the same financial intermediary, suffered a reduction relative to the rest of the market. This result is true for the mean, median and the whole distribution of bond prices, and robust to an extensive sensitivity analysis. We interpret it as evidence that the identity of the financial intermediary was informative, i.e, investors extracted information about the soundness of a debtor based on the existence of financial relationships. This spillover, informational in essence, arises as the flip-side of the relational lending coin: contagion arises for the same reason why relational finance, in this case, underwriting, helps alleviate informational and incentive problems.

A emergência da governança socioambiental no mercado internacional de biocombustíveis

O esgotamento das reservas de energia fóssil e o processo de mudanças climáticas causadas pelas emissões de GEEs posicionaram os biocombustíveis como a principal fonte alternativa de energia renovável disponível para uso em transportes no curto e médio prazos. Contudo, a presença de externalidades e assimetrias de informação dificultam a verificação da sustentabilidade neste setor. Assim, a emergência do mercado internacional de biocombustíveis mostra-se condicionada pela construção de instituições que garantam a sustentabilidade da produção e consumo desses produtos. O processo de construção das instituições de governança socioambiental é afetado por fatores de ordem técnica, política e institucional. Apoiado em aportes teóricos do institucionalismo econômico e sociológico, o presente estudo buscou analisar que elementos afetam este processo considerando a trajetória de mercados já estabelecidos que apresentam caraterísticas análogas ao setor de biocombustíveis (alimentos orgânicos e produtos florestais). A forma como legislações nacionais, acordos internacionais e sistemas de certificação privada se desenvolveram e interagiram nesses setores apresenta aderência com o processo de construção do mercado de biocombustíveis observado até o momento. Dentre os resultados encontrados, observa-se tendência à convergência entre padrões de sustentabilidade em diferentes legislações nacionais e sistemas de certificação privados devido às externalidades de rede que conferem maior valor a padrões adotados por uma gama mais ampla de usuários. A União Europeia desponta como o principal formador de padrões de sustentabilidade, dado seu perfil importador e o estabelecimento de critérios mais amplos nas legislações dos Estados Membros, geralmente implementada via integração de mecanismos de governança públicos e privados (meta-standards). Apesar do expressivo potencial de consumo, os EUA apresentam menor influência nesse processo devido a considerável capacidade de produção doméstica e a priorização de elementos estratégicos (segurança energética e desenvolvimento rural) no desenho de suas políticas de sustentabilidade para combustíveis de biomassa. Na esfera privada, o desenvolvimento de sistemas de certificação apresenta-se condicionado por elementos técnicos, como a eficiência em cobrir critérios relevantes e os custos incorridos neste processo; e políticos, relacionados à capacidade de legitimição dos atores envolvidos em cada um destes programas de certificação. Também se observa que caraterísticas tecnológicas e organizacionais das cadeias de produção de biocombustíveis afetam a expansão de sistemas de certificação, condicionando tanto os custos para o estabelecimento da cadeia de custódia como a capacidade de coordenação de ações setoriais visando a adoção de práticas sustentáveis que facilitem a obtenção da certificação. Essa relação fica evidente em novas nações que buscam estabelecer um setor bioenergético e enfrentam dificuldades em integrar a agricultura familiar à modelos de produção que respeitem critérios socioambientais vigentes no mercado internacional. A pesquisa revelou a necessidade de um entendimento mais aprofundado da interconexão de novas rotas tecnológicas e atores adentrando no mercado internacional de biocombustíveis. A compreensão dos riscos e potencialidades de novas formas de interação pública e privada na governança socioambiental apresenta-se como um campo prolífico para futuros estudos neste setor e em outros em que atributos ambientais se mostrem relevantes.

A dynamic model of simultaneous price competition with switching and search costs

Esse artigo apresenta um modelo dinâmico de competição em precos que incorpora tanto custos de procura quanto custos de switching e onde que as decisões do consumidor e das firmas são simultâneas. Dadas as hipóteses feitas n ós veremos que este modelo possui equilí brio. As principais propriedades do equil íbrio deste modelo são: Se os custos de procura forem baixos o suficiente, em equilí brio o consumidor vai procurar todas as firmas no mercado enquanto que o aumento dos custos de procura vai reduzir a propor cão de firmas que o consumidor busca. Um resultado contraintuitivo e que os pre cos esperados pagos pelo consumidor normalmente decresce em nossas computa cões numéricas do equil íbrio quando os custos de procura aumentam. Enquanto que aumentar os custos de switching tamb ém vai produzir o resultado contraituitivo que as firmas unmatched vão diminuir suas ofertas de modo a atrair o consumidor.

R&D investment, international trade, and home market and competitiveness efects

We analyze the effects of R&D investment on international trade. The importance of studying this comes from the fact that one of the most important characteristics of modern industrial organization is that firms try to influence market behavior through strategic variables as R&D. Moreover international competition between firms is, more and more, also centered in R&D competition (besides output and price competition). With this in mind, we develop an oligopolist reciprocal-markets model where firms engage in R&D investment to achieve future reductions in marginal costs. We find ‘home market effects’ at the level of R&D investment, i.e.: firms located in countries that host a higher share of skilled-labor perform higher levels of R&D investment. As consequence, firms in these countries are more competitive than firms in other countries, and as such they can penetrate more easily foreign markets. As result of this ‘competitiveness effect’, countries where these firms are located run trade surplus, while countries where firms perform lower levels of R&D investment incur in trade deficits.

Determinants of differential pricing of equity classes in the Brazilian equity market

We examine the differential pricing of equity classes between voting and non-voting shares in Brazilian listed companies with particular emphasis on privatized companies, and we discuss the role of majority control, liquidity, and governance issues that may influence these differentials over time. We include a brief discussion on the Brazilian corporate law system, its impact on controlling and minority shareholders, and the characteristics of the Brazilian privatization process, before proceeding to the econometric analysis. We find empirical evidence to support that liquidity is a major component for determining this differential pricing over time. Other variables, such as the ratio of non-voting equity to total equity, type of majority control, and changes in regulation signal the high level of agency costs between majority controllers and minority shareholders in explaining the differential pricing of equity classes.

A restatement of the welafare costs of inflation. The wast of scarce resources in the manufacturing , banking and household sectors

Lucas (2000) estimates that the US welfare costs of inflation are around 1% of GDP. This measurement is consistent with a speci…c distorting channel in terms of the Bailey triangle under the demand for monetary base schedule (outside money): the displacement of resources from the production of consumption goods to the household transaction time à la Baumol. Here, we consider also several new types of distortions in the manufacturing and banking industries. Our new evidences show that both banks and firms demand special occupational employments to avoid the inflation tax. We de…ne the concept of ”the foat labor”: The occupational employments that are aflected by the in‡ation rates. More administrative workers are hired relatively to the bluecollar workers for producing consumption goods. This new phenomenon makes the manufacturing industry more roundabout. To take into account this new stylized fact and others, we redo at same time both ”The model 5: A Banking Sector -2” formulated by Lucas (1993) and ”The Competitive Banking System” proposed by Yoshino (1993). This modelling allows us to characterize better the new types of misallocations. We …nd that the maximum value of the resources wasted by the US economy happened in the years 1980-81, after the 2nd oil shock. In these years, we estimate the excess resources that are allocated for every speci…c distorting channel: i) The US commercial banks spent additional resources of around 2% of GDP; ii) For the purpose of the firm foating time were used between 2.4% and 4.1% of GDP); and iii) For the household transaction time were allocated between 3.1% and 4.5 % of GDP. The Bailey triangle under the demand for the monetary base schedule represented around 1% of GDP, which is consistent with Lucas (2000). We estimate that the US total welfare costs of in‡ation were around 10% of GDP in terms of the consumption goods foregone. The big di¤erence between our results and Lucas (2000) are mainly due to the Harberger triangle in the market for loans (inside money) which makes part of the household transaction time, of the …rm ‡oat labor and of the distortion in the banking industry. This triangle arises due to the widening interest rates spread in the presence of a distorting inflation tax and under a fractionally reserve system. The Harberger triangle can represent 80% of the total welfare costs of inflation while the remaining percentage is split almost equally between the Bailey triangle and the resources used for the bank services. Finally, we formulate several theorems in terms of the optimal nonneutral monetary policy so as to compare with the classical monetary theory.

On the efficiency of the Argentinean electricity wholesale market

This paper discusses two key aspects regarding the efficiency of the Argentinean Electricity Market. Using hourly data on prices, marginal costs, and operational status of generators, it will be argued that, unlike the former British and Californian electricity spot markets, this market is not subject to the conventional forms of exercise of market power by generators. We then use Chao's (1983) model of optimal configuation of electricity supply to evaluate the social desirability of the change in the supply pattern of the Argentinean electricity industry, which took place throughout the last ten years.
