arroz, comercialização agrícola, política de preçosResumo
Este estudo examina como os preços do arroz são transferidos dos agricultores para outras agências de comercialização. Este estudo utiliza dados mensais sobre os preços do arroz aos níveis de produtor (agricultor), moinho de arroz e grossista de 2010 a 2024 na Indonésia. Enquanto isso, o método utilizado neste estudo é a regressão do Modelo de Correção de Erros. Os resultados indicam a presença de integração de mercado e assimetria na transmissão vertical dos preços do arroz entre os agricultores e outras agências de comercialização, tanto a curto como a longo prazo. A transmissão assimétrica de preços resulta do abuso de poder de mercado e dos custos de ajustamento. O governo deve monitorizar os preços do arroz, garantir o comércio justo, detetar irregularidades e incentivar o aumento da participação nos mercados do arroz.
