The analysis of the evolution of the M3 money aggregate is an important element in the definition and implementation of monetary policy for the ECB. A well-defined and stable long run demand function is an essential requisite for M3 to be a valid monetary tool. Therefore, this paper analyzes based in cointegration techniques the existence of a long run money demand, estimating it and testing its stability for the Euro Area and for ten of its member countries. Specifically, bearing in mind the high degree of monetary instability that the current economic crisis has created in the Euro Area, we also test whether this has had a noticeable impact in the cointegration among real money demand and its determinants. The analysis gives evidence of the existence of a long run relationship when the aggregated Euro Area and six of the ten countries are considered. However, these relationships are highly instable since the outbreak of the financial crisis, leading in some cases to even rejecting cointegration. All this suggests that the ECB’s strategy of focusing in the M3 monetary aggregates could not be a convenient approach under the current circumstances

A importância do transporte aquaviário é dada pelos diferentes modos de navegação, podendo ser por meio fluvial, lacustre e navegação marítima. Para a logística e economia brasileira, este é um modal extremamente importante, haja vista a pluralidade de transporte pelo fato das relações de exportação e importação ocorrerem especialmente por este tipo de modal. No Brasil há cinco modalidades de transportes: o aquaviário, o rodoviário, o aeroviário, o ferroviário e o dutoviário. Serão descritas nos próximos capítulos as características de cada tipo de modal, especificamente dos modais rodoviário e aquaviário, em especial a cabotagem, objeto principal deste estudo. O objetivo deste trabalho é analisar a atual situação do transporte marítimo no Brasil, especialmente a cabotagem. Através de três parâmetros - custos, tempo de viagem e segurança -, procurar-se-á avaliar o nível de qualidade do modal, visando à identificação da existência de pontos críticos e sugerir possíveis soluções baseadas na logística e na tecnologia, ferramentas fundamentais para a busca da eficácia na redução dos custos de transportes, contribuindo para um melhor resultado dos custos logísticos finais. Para uma reflexão sobre o transporte nacional de mercadorias por via marítima através da cabotagem, serão apresentadas as características principais do transporte marítimo, com suas vantagens e desvantagens e sua importância para a economia brasileira. A crítica envolverá a questão do frete marítimo e suas interrelações, discutindo variáveis que compõem o preço do frete. Ferramentas tecnológicas fundamentais para a eficácia das operações também serão abordadas durante este trabalho. Serão descritas as características dos portos brasileiros, em especial as dos portos do Rio Grande (RS), Santos (SP), Suape (PE) e Rio de Janeiro (RJ), a distancia entre o porto do Rio de Janeiro (RJ) e os demais, bem como o tempo de viagem relacionado entre eles. Explorado pela União diretamente ou mediante concessão (precedida de licitação), o porto organizado, construído e aparelhado para atender necessidades da navegação e da movimentação é administrado pelo Conselho de Autoridade Portuária - CAP -, contando ainda com a figura do OGMO Orgão Gestor de Mão de Obra que controla a força de trabalho nas áreas portuárias, organismos instituídos pela Lei n. 8.630, de 25 de fevereiro de 1993, chamada da Lei de Modernização dos Portos. Por fim serão analisadas as variáveis custo, tempo de viagem e segurança no intuito de contribuir para uma reflexão para o crescimento do transporte de cabotagem no Brasil, procurando identificar um ganho substancial na economia brasileira, através da economia de escala, observados todos os parâmetros necessários para o bom desenvolvimento da logística de transporte de mercadorias por via marítima. Este trabalho abordará a Gestão do Transporte Marítimo de Cargas no Brasil, em especial a cabotagem.

Fishery managers are mandated to understand the effects that environmental damage, fishery regulations, and habitat improvement projects have on the net benefits that recreational anglers derive from their sport. Since 1994, the National Marine Fisheries Service (NMFS) has worked to develop a consistent method for estimating net benefits through site choice models of recreational trip demand. In estimating net benefits with these models, there is a tradeoff between computational efficiency and angler behavior in reality. This article examines this tradeoff by considering the sensitivity of angler-welfare estimates for an increase in striped bass (Morone saxatalis) angling quality across choice sets with five travel distance cutoffs and compares those estimates to a model with an unrestricted choice set. This article shows that 95% confidence intervals for welfare estimates of an increase in the striped bass catch and keep rate overlap for all distance-based choice sets specified here.

In this article the demand for fish and its substitute was estimated using a very flexible demand function, the Almost Ideal Demand System (AIDS) developed by Deaton and Muelllbaeur (1980), incorporating the habit formation variable to measure the impact of the changes in tastes in comsumer demand for fish and meat products from 1960 to 1990 in Malaysia. Information on price and income elasticities for these meat groups was also obtained. To incorporate consumption habit variables, the dynamic translating procedure proposed by Pollak (1970) and Pollak and Wales (1981) has been adopted. The overall results of the maximum likelihood estimates of the dynamic AIDS model are quite good where 19 of 30 coefficients are significantly different from zero and the minimum budget shares, the constant, are between zero and one for each meat type. Consumers tend to purchase and consume fish, chicken, and pork almost daily. Beef and mutton are only consumed occassionally since they are relatively more expensive. This finding is consistent with the trend observed in the per capita consumption and budget share where fish, chicken, and pork tended to dominate over beef and mutton from 1960 to 1990.

In the past, agricultural researchers tended to ignore the fisheries factor in global food and nutritional security. However, the role of fish is becoming critical as a result of changes in fisheries regimes, income distribution, demand and increasing international trade. Fish has become the fastest growing food commodity in international trade and this is raising concern for the supply of fish for poorer people. As a result, the impact of international trade regimes on fish supply and demand, and the consequences on the availability of fish for developing countries need to be studied. Policies aimed at increasing export earnings are in conflict with those aimed at increasing food security in third world countries. Fisheries policy research will need to focus on three primary areas which have an impact on the marginal and poorer communities of developing countries: increased international demand for low-value fish on the supply of poorer countries; improved aquaculture technologies and productivity on poorer and marginal farmers; and land and water allocation policy on productivity, food security and sustainability across farm, fishery and related sectors. The key to local food security is in the integration of agriculture, aquaculture and natural resources but an important focus on fisheries policy research will be to look at the linkages between societal, economic and natural systems in order to develop adequate and flexible solutions to achieve sustainable use of aquatic resources systems.
