Resumo

Este estudo analisa a transmissão de risco e volatilidade no mercado pecuário do Paraná, Brasil, usando o modelo TVP-VAR, no período de janeiro de 1995 a março de 2024. Examina conectividade, spillovers de volatilidade e assimetria, com foco na produção de carne bovina e nas interações entre commodities pecuárias e grãos. Evidências mostram que crises internacionais ampliam a transferência de volatilidade, afetando mais os mercados internos. Ao compreender essas dinâmicas, o estudo contribui para o desenvolvimento de estratégias mais avançadas de estabilidade de preços e gestão de riscos no setor pecuário, com implicações para as políticas econômicas regionais e nacionais.

Abstract

Abstract: This study analyzes the transmission of risk and volatility in the cattle market in Paraná, Brazil, using the TVP-VAR model, from January 1995 to March 2024. It examines connectivity, volatility spillovers and asymmetry, focusing on beef production and interactions between livestock commodities and grains. Evidence shows that international crises amplify the transfer of volatility, affecting domestic markets more. By understanding these dynamics, the study contributes to the development of more advanced price stability and risk management strategies in the livestock sector, with implications for regional and national economic policies.
