Análise da oferta e demanda de exportações de pescado: o caso do comércio entre o Ceará e os Estados Unidos

Abstract

This work has as main objective to analyze the trade in fish between Ceará and the United States in the period 1996 to 2008, based on the estimation of supply and demand equations, graphs and growth rates. Based on the results it is concluded that North American demand for fish Ceará showed an increasing trend and offer presented inverse behavior. The estimated equations show that, due to heavy reliance of exporters on the market, producers are more sensitive to changes in prices than the consumer. In Ceará the fish market is considered as a standard of luxury, as the main products exported are shrimp, crawfish, and the frozen fish. Thus, an increase in income of consumers will increase exports of the fisheries sector Ceará. Among the variables included in the model, the exchange rate is that which has greater influence on exports. This is because the exchange rate changes cause changes in both external prices as the purchasing power of consumers. These two variables together, in turn, affect both the supply and demand.
