Os Sistemas Agroflorestais (SAFs) de cacaueiro da BR-230 além de ser uma alternativa para a recuperação de áreas desmatadas e degradadas da Amazônia são capazes de integrar floresta e agricultura proporcionando serviços ambientais como a manutenção da biodiversidade, o ciclo da água e o estoque de carbono. Porém, a lógica econômica do mercado de cacau não leva em consideração as falhas de mercado, sobretudo não internaliza as externalidades positivas dos serviços ambientais, principalmente o carbono dos Sistemas Agroflorestais de cacaueiro da BR-230. Portanto, o produtor rural não é compensado por este esforço em manter o serviço ambiental carbono em sua atividade. Assim, neste trabalho apresentamos um mecanismo de compensação com uma metodologia para o REDD para atividades produtivas a partir do estudo do Custo Marginal Privado e do Benefício Marginal Privado do mercado de cacau do Estado do Pará e, usando parâmetros da atividade produtiva dos SAFs de cacaueiro da BR-230, como o Carbono Estocado no Tempo para compor o Benefício Socioambiental. Este Benefício Socioambiental é composto pela Produtividade da Atividade, Valor do Carbono Estocado e primordialmente pelo Carbono Estocado no Tempo dos SAFs de cacaueiro para um período de trinta anos. Do estudo resultou a ferramenta do Benefício Socioambiental para solucionar os problemas da falha de mercado para a implantação do REDD para o produtor rural da SAF, mecanismo de compensação baseado na política de externalidade socioambiental positiva justificado pela Taxa Pigouviana. Portanto, o mecanismo de compensação apresenta uma visão de integração entre as dimensões social, econômica e ambiental como lógica diferente para os produtores rurais de SAFs da rodovia Transamazônica que promove benefícios para a conservação e preservação sem desmatamento e sem degradação para que o produtor continue perpetuando a conservação possibilitando um acréscimo na renda do produtor rural no período onde há maior custo da atividade e nenhuma receita de retorno e, nos últimos anos como forma de investimento de uma renovação da área em uso com um novo plantio ou com a manutenção de uma área antiga ou implantação de nova área de SAF. Desta forma, este mecanismo de compensação é um importante fator no financiamento de um novo modelo de desenvolvimento da Amazônia com uma política de REDD.

The importance of the capital market to Brazilian economic development, linked to the the fragility of a theoretical framework on the issue, case for developing this research. The agents operating in the capital market seek security and confidence for decision making on their investment in that sense we seek to address the concept and values of Corporate Governance to pay in the Brazilian capital market. The Corporate Governance, in its essence, is the system by which companies are directed and monitored, involving the relationship between shareholders and the board of companies, as well as a set of mechanisms and factors intended to minimize market failures. Seeking to confirm adherence to a more advanced system of corporate governance can result in a favorable financial performance, companies were investigated operating in the financial sector (intermediation, various services and insurance), listed by BM&FBOVESPA. The stock market ranks the corporate governance systems in three levels: Level 1 (rudimentary), Level 2 (intermediate) and New Market Level (advanced). To earn the impact of different levels of Corporate Governance for the outcome of the selected companies were calculated and analyzed accounting ratios of profitability, capital structure and liquidity from the Standardized Financial Statements (DFP), base year 2011, 2012 and 2013

The purpose of this paper is to essentially provide a theoretical framework to industrial policies, especially showing the reasons for preference of a theoretical framework that is not based on equilibrium, and not based on maximization. We sought to define these policies, highlighting their positive results – at least potentially – in terms of some parameters (production, efficiency, productivity, income, welfare etc.). In this sense, we defined industrial policy, also analyzing the reasons for the usual lack of concern with a more rigorous theoretical framework for industrial policies. Following that, we briefly discussed whether or not a certain theory can lay the foundation for these policies, also examining if such theories are important (or not) in empirical terms. In the fourth section, we investigated the possible use of industrial policies, emphasizing market failures, public goods, non-competitive markets, externalities and technological development. Finally, we discussed about evaluation approaches of industrial and technological policies, focusing with more detail on the challenges related to the evaluation of economic effects of industrial and technological policies, and the methodologies of evaluation of these policies.

The relationship between trade and culture can be singled-out and deservedly labelled as unique in the discussion of 'trade and ...' issues. The reasons for this exceptional quality lie in the intensity of the relationship, which is indeed most often framed as 'trade versus culture' and has been a significant stumbling block, especially as audiovisual services are concerned, in the Uruguay Round and in the subsequent developments. The second specificity of the relationship is that the international community has organised its efforts in a rather effective manner to offset the lack of satisfying solutions within the framework of the WTO. The legally binding UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions is a clear sign of the potency of the international endeavour, on the one hand, and of the (almost desperate) desire to contest the existing WTO norms in the field of trade and culture, on the other. A third distinctive characteristic of the pair 'trade and culture', which is rarely mentioned and blissfully ignored in any Geneva or Paris talks, is that while the pro-trade and pro-culture opponents have been digging deeper in their respective trenches, the environment where trade and cultural issues are to be regulated has radically changed. The emergence and spread of digital technologies have modified profoundly the conditions for cultural content creation, distribution and access, and rendered some of the associated market failures obsolete, thus mitigating to a substantial degree the 'clash' nature of trade and culture. Against this backdrop, the present paper analyses in a finer-grained manner the move from 'trade and culture' towards 'trade versus culture'. It argues that both the domain of trade and that of culture have suffered from the aspirations to draw clearer lines between the WTO and other trade-related issues, charging the conflict to an extent that leaves few opportunities for practical solutions, which in an advanced digital setting would have been feasible.

Free riders and holdouts are market failures that potentially impede the completion of otherwise beneficial transactions. The key difference is that the free rider problem is a demand side externality that requires taxation to compel payment for a public good, while the holdout problem is a supply side externality that requires eminent domain to force the sale of land for large scale projects. This paper highlights that distinction between these two problems and uses the resulting insights to clarify the meaning of the public use requirement of the Fifth Amendment takings clause.

Using a unique dataset obtained from rural Andhra Pradesh, India that contains direct observations of household access to credit and detailed time use, results of this study indicate that credit market failures lead to a substantial reallocation of time used by children for activities such as schooling, household chores, remunerative work, and leisure. The negative effects of credit constraints on schooling amount to a 60% decrease of average schooling time. However, the magnitude of decrease due to credit constraints is about half that of the increase in both domestic and remunerative child labor, the other half appearing to come from a reduction in leisure.

This paper analyses the consequences of urban environmental degradation on the well-being of Spanish miners. It is based on analyses of differences in mortality and height. The first part of the paper examines new hypotheses regarding the urban penalty. We take into consideration existing works in economic theory that address market failures when analysing the higher urban death rate. We explain the reduction in height using the model recently created by Floud, Fogel, Harris and Hong for British cities. The second part of the paper presents information demonstrating that the urban areas in the two largest mining areas in Spain (Bilbao and the Cartagena-La Unión mountain range) experienced a higher death rate relative to rural areas as a consequence of market failures derived from what we term an ‘anarchic urbanisation’.

The SME access-to-finance problem is not universal in the European Union and there are reasons for the fall in credit aggregates and higher SME lending rates in southern Europe. Possible market failures, high unemployment and externalities justify making greater and easier access to finance for SMEs a top priority. Previous European initiatives were able to support only a tiny fraction of Europe’s SMEs; merely stepping-up these programmes is unlikely to result in a breakthrough. Without repairing bank balance sheets and resuming economic growth, initiatives to help SMEs get access to finance will have limited success. The European Central Bank can foster bank recapitalisation by performing in the toughest possible way the asset quality review before it takes over the single supervisory role. Of the possible initiatives for fostering SME access to finance, a properly designed scheme for targeted central bank lending seems to be the best complement to the banking clean-up, but other options, such as increased European Investment Bank lending and the promotion of securitisation of SME loans, should also be explored.
