ECONOMIC DISRUPTION FROM CORONAVIRUS DISEASE 2019 (COVID-19) HAS RESULTED IN INCREASED FOCUS ON PRICE TRANSMISSION AND MARKETING MARGINS IN U.S. LIVESTOCK SECTORS. MEAT PACKERS HAVE BEEN ACCUSED OF UNFAIR BUSINESS PRACTICES BECAUSE OF LOW PRICES AT THE FARM GATE AND INCREASED DEMAND FOR MEAT AT RETAIL. BEEF, PORK, AND POULTRY PROCESSING PLANTS HAVE BEEN CLOSING OR REDUCING OPERATIONS AS WORKERS BECOME INFECTED, BUT ARE NOW REOPENING UNDER THE DEFENSE PRODUCTION ACT. THIS PROJECT WILL EMPIRICALLY ASSESS THE IMPACT OF COVID-19 ON PRICE LINKAGES ACROSS FARM, WHOLESALE, AND RETAIL LEVELS OF THE BEEF, PORK, AND POULTRY SUPPLY CHAINS AND DEVELOP METHODS TO STATISTICALLY TEST FOR INEFFICIENCIES IN THESE MARKETS. IT IS CONSISTENT WITH THE GOALS OF THE AGRICULTURE AND FOOD RESEARCH INITIATIVE TO PROVIDE SCIENCE-BASED EVIDENCE FOR PUBLIC POLICY AND RAPID RESPONSE TO THE COVID-19 PANDEMIC.BECAUSE THE PANDEMIC IS ONGOING, WE WILL COLLECT DATA AT SEVERAL TEMPORAL RESOLUTIONS TO ENSURE THAT RESULTS ARE ROBUST AND PROVIDE EARLY EVIDENCE OF MARKET IMPACTS. DATA WILL BE UPDATED THROUGHOUT THE PERIOD OF PERFORMANCE FOR NEAR REAL-TIME ANALYSIS. TIME SERIES MODELS WITH THE ABILITY TO INCORPORATE NONLINEAR AND ASYMMETRIC PRICE BEHAVIOR CAN CAPTURE THE PRICE IMPACTS OF EXTREME EVENTS. WE WILL DEVELOP BAYESIAN MODELS WITH A HIGH DEGREE OF FLEXIBILITY THAT CAN ACCOUNT FOR INTENSITY OF THE PANDEMIC; WE WILL APPLY THESE METHODS TO EXAMINE INDICATORS OF NONCOMPETITIVE MARKETS AND ABNORMAL PRICE RESPONSES. RESULTS WILL BE DISSEMINATED TO POLICYMAKERS, ACADEMICS, AND INDUSTRY STAKEHOLDERS TO INFORM PUBLIC POLICY AND CONTINUED RESEARCH.
