Commodity Forecasting in the U.S. Department of Agriculture Presentation for Vietnamese Officials February 2006 William Hahn Senior Economist, Market and Trade Economics Economic Research Service, USDA
Overview • What are USDA’s goals in developing its commodity market forecasts? • What is USDA’s process for developing short-term (year ahead) forecasts? • What types of projections does USDA make for the longer-term? • Why does USDA develop forecasts?
Goals of USDA’s Outlook Program... • …To provide information, data, and analysis that: • Is insightful, objective, and available to all players in the market. • Reaches key users (both public and private) in a timely, easy-to-access fashion. • Enhances decisionmaking and relies on customer feedback. • Improves the transparency of markets and their interactions with policies and institutions.
Special Issues in AgricultureAffect Forecasting • In the U.S., government programs have historically had an impact on the sector. • Nature and biological cycles are important: • Biological production lags for livestock. • Annual production cycle for crops. • Demand is relatively inelastic compared to many non-agricultural commodities.
Interagency Committees Coordinate Agricultural Commodity Forecasts • Five USDA agencies develop these forecasts, which are coordinated by World Agricultural Outlook Board “committees” (wheat, rice, etc.). • Annual forecasts are developed monthly for: • Crops--Wheat, rice, feed grains, oilseeds, cotton, sugar. • Livestock--Meat animals, poultry, dairy. • “WASDE” is issued between the 8th and 12th of each month.
WAOB • Coordinate and document interagency review and clearance • Short-run modeling • Maintain detailed commodity specific data and economic parameters • NASS liaison • FAS • Foreign Market Intelligence • Global Supply / Demand • Trade Flows: Short-run • Export Sales • Trade Statistics • Trade Policy • FSA • U.S. Farm Program Participation • Program Decisions • Budget Liaison • Program Support • Mandatory Reports • AMS • Domestic Market Intelligence • Wholesale Prices • Warehouse Inventories • Shipments Data • Grain Inspections • Border Crossings • ERS • Objective Economic Analysis • Survey and Evaluation of Current Information • Trade Economics: Medium- and Long-run • Food, Seed, Industrial Use • NASS • Planting Intentions • Crop Condition Assessment • Production and Stocks Estimates • Season Average Prices • Inventory Numbers • Marketing and Slaughter Data Numerous Agencies Are Involved in Developing USDA Forecasts • INTERAGENCY COMMODITY • ESTIMATES COMMITTEES • Serve as focal point for USDA situation and outlook program • Bring all relevant expertise within Department to bear on commodity and sector situation and outlook assessments • Assimilate information and forecasts reflecting unique agency expertise • Construct consistent country. regional, and global supply and use estimates for Interagency review and approval • Assure objectivity of USDA economic assessments • Evaluate non-USDA analytical results and information sources • Achieve Department-wide consensus on current issues affecting commodity markets • Assure consistency among USDA published and internal estimates • Present analytical results to policymakers and others • JAWF • Weather Information • Weather and Crop Yield Assessments • Early Warnings
Two USDA Agencies in the Process Focus on Primary Data Collection • National Agricultural Statistics Service (NASS)— • Variables: Stocks, acreage, yields, production, prices received by farmers. • Extensive surveys of elevators, farmers, etc. • Staff at state offices interact with producers and industry. • Agricultural Marketing Service (AMS)— • Daily and weekly price reporting at selected markets. • Extensive field staff collect and report data. • Accounts for largest number of USDA market releases, but many are quite brief.
Three Other Agencies AlsoHave Unique Roles… • Farm Service Agency (FSA)— • Administrative data used in implementation of farm programs. • Foreign Agricultural Service (FAS)— • Supply and use for major commodities in foreign countries based on attache reports, satellite imagery, etc. • Economic Research Service (ERS)— • Short- and longer-term analysis of all aspects of supply and demand. • Both domestic and international market expertise.
Forecasts Integrate Data, Models,Statistical Analysis, and Judgment • The monthly forecasting process combines: • Data--Survey data of producers and industry. • Economic models and statistical analysis--Of all aspects of the balance sheet. • Expert judgment--Added information brought to the process. • Forecasts developed during a 2-week process. • Culminates in “lock-up” and 8:30 a.m. release of World Agricultural Supply and Demand Estimates (WASDE).

WASDE Contains Information On Each Month’s Forecasting Accuracy
USDA Also Develops 10-Year Agricultural Baseline Projections • Prepared using similar interagency process. • Based on: • Specific policy assumptions which may or may not turn out to be accurate. • Composite of models and judgmental analysis. • Published in USDA annual report distributed at the February Agricultural Outlook Forum. • Distributed through the ERS website: • http://www.ers.usda.gov/Features/Baseline/Baseline2006/
At ERS, Forecasting and Research Programs Are Strongly Intertwined Research Issues Draw from Forecasts and Special Studies Results Feed Back to Forecasts and Studies Forecasting Short-term Forecasts Long-term Baseline Analytical Systems Draw on Each Other Special Studies Policy Analysis Trade Analysis Staff Analysis
Why Does USDA Forecast Supply, Use, and Prices? • Ensures availability of basic data and information to all in the marketplace—big companies and small farmers alike. • Provides process for forecasting key variables in important global markets. • Critical to USDA decision-making on trade policy, domestic programs, etc.
