Dissertação (Mestrado em Agronegócio) - Universidade Federal de Goiás, Goiânia, 2018.http://repositorio.bc.ufg.br/tede/handle/tede/8366An important characteristic of agricultural production is the volatility of the prices of its products, caused by excess supply in the harvest period and shortage in the off-season, in addition to other factors intrinsic to the activity. Despite the complexity ofthe real economy, specific methodologies are used to verify the effects of public policies that aim to stabilize agribusiness prices. In Brazil, has been history the Minimum Price Guarantee Policy, which since 1943 aims to guarantee minimum income for rural producers. The objective of this work is to collect specialized literature on the subject and to verify which methodology is most appropriate to measure the effects ofthe PGPM on agricultura 1 prices, then to use the same methodology to verify the effects ofthe PGPM on maize prices in the State of Mato Grosso, which is the largest Brazilian producer of this important grain. The hypothesis is that the PGPM would have positive and significant effects on prices, however, through the identification and use of the most appropriate model presented in the literature, which were the Models of Intervention Analysis in Time Series, the results indicated that Interventions (PGPM) on prices did not represent a positive and significant homogeneous effect, creating evidence that in Mato Grosso, from 2005 to 2016, other market variables explain the price changes in addition to these PGPM instruments.application/pdfAcesso AbertoPGPMMilhoAnálise de intervençãoCornIntervention analvsisCIENCIAS AGRARIAS::AGRONOMIADissertação
