This dissertation presents three essays that investigate three relevant issues about agricultural markets: farmers’ choice of hedge; government optimal taxation; and government farm program reactions to price volatility. First essay fills a theoretical gap showing that high profitable farmers hedge more than low profitable farmers. Second essay examines government optimal taxation and shows how Ramsey government policies compete with financial markets. The third essay shows the causality from price volatility to government subsidies using US wheat market data. It also shows that government reacts to price volatility, mainly, when prices are low enough, despite the farm program design.
