**AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** THE UNITED STATES IS THE LEADING EXPORTER OF MANY AGRICULTURAL COMMODITIES, SO THE EXPORT MARKET IS VITAL FOR U.S. FARMERS, GROWERS, AND AGRIBUSINESS FIRMS. GREATER PROPENSITY TO PROVIDE FARM SUBSIDIES BY MANY IMPORTING COUNTRIES AND INCREASING TRADE TENSIONS, AS HAVE BEEN PLAYING OUT RECENTLY, WILL HARM THE U.S. AGRICULTURAL SECTOR. CONSEQUENTLY, IT IS IMPORTANT TO ASSESS HOW DOMESTIC AND TRADE POLICIES OF COUNTRIES IMPEDE U.S. EXPORTS AND THE SUSTAINABILITY OF U.S. AGRICULTURE. THE OBJECTIVES OF THIS PROJECT ARE TO:1. DEVELOP A COMPREHENSIVE THEORETICAL TRADE MODEL ENCOMPASSING RICARDIAN AND HECKSCHER-OHLIN COMPARATIVE ADVANTAGE, DOMESTIC POLICIES, TRADE POLICIES, AND GEOGRAPHICAL DISTANCES;2. EMPIRICALLY IMPLEMENT THE THEORETICAL MODEL USING THE STATE-OF-ART ECONOMETRIC METHODS TO QUANTIFY THESE EFFECTS ON U.S. COMMODITY EXPORTS, PRICES, SUPPLY, DEMAND, AND FARM PROFITS;3. ANALYZE THE EFFECTS OF THE FOLLOWING TRADE AGREEMENTS ON U.S. AGRICULTURE: A. USMCA AGREEMENT; B. COMPREHENSIVE AND PROGRESSIVE AGREEMENT FOR TRANS-PACIFIC PARTNERSHIP POLICIES; C. RECENT TRADE WAR BETWEEN THE UNITED STATES VERSUS CHINA, CANADA, MEXICO, INDIA, AND THE EUROPEAN UNION; D. THE EUROPEAN UNION AND JAPAN FREE TRADE AGREEMENT.
