1 Interaction Effects of Promotion, Research, and Price Support Programs for U.S. Cotton Robert H. Beach, RTI Brian C. Murray, RTI Nicholas E. Piggott, NCSU Michael K. Wohlgenant, NCSU AAEA Annual Meetings July 30, 2002

2 Objectives Examine Nature of Interaction Effects Empirically Determine Magnitude Implications 2

3 Agricultural Commodity Markets Government Programs Support Prices Supplement Incomes Manage Supplies Checkoff Programs Increase Commodity Demand Increase Producer Profits 3

4 Checkoff Programs Producers Vote to Institute Producers Retain Right to End Programs Pecans Limes Pork Need for Estimates of Returns 4

5 U.S. Cotton Substantial Checkoff Program $67 million in 2000 Market with Large Subsidies for: Cotton Producers Consuming Textile Mills 5

6 Cotton Research and Promotion Program Background 1966 Cotton Research & Promotion Order 1990 Amendments Activities Promotion (~66% of Budget) Fiber and Textile Research (~16%) Agricultural Research (~11%) 6

7 Selected Federal Farm Programs for Cotton Cotton Producers Marketing Assistance Loans Loan Deficiency Payment (LDP) Textile Mills Step 2 Program 7

8 Effective Prices Demand Price Net of Step 2 subsidy Supply Price Expected price (including per-unit government payments) 8

Farm Program Interactions S S PS P S1 = P M1 + (P L - P W ) P * m1 PS P S0 = P M0 + (P L - P W ) LDP (Ex Post LDP Payment to Farmers) 1 * P m0 P L LDP 0 (Initial LDP Payment to Farmers) D 1 (with CRPP) P M1 P M0 P W1 P W0 D 0 D 0 D 1 Q 0 * Q 1 * (a) Free Market: No Program Effects From LDP or STEP 2 Here P m * = Market Price = Supplier Price = Demand Price PS = Producer Benefits from Demand Shift (b) LDP Effects (When Binding) P W < P L P M = Market Price = Demand Price P S = P M + (P L - P W ) = Supply Price P W = World Price, where P W = F (P M ) P L = LDP Rate (Fixed) (Shift effects on producer price:) P S = (P S1 - P S0 ) = (P M1 - P M0 ) - (P W1 - P W0 ) = P M - P W Since P W > 0, then PS < PM (Also LDP 1, < LDP 0 ) Calculate P S accordingly PS PS S P m1 P S1 = P M1 + (P L - P W1 ) P m0 P S0 = P M0 + (P L - P W0 ) * P m1 * P m0 S2 1 : Step 2 payment after shift S2 0 : Step 2 payment initial P P m1 L P* P m1 m0 P m0 * P w1 P w0 P w1 P w0 D 1 D 1 Q 1 Q 0 * * Q 0 Q 1 D 0 Q 0 * Q 1 * Q 0 Q 1 D 0 (c) Step 2 Program Effects P m = Market Price = Supply Price P W = World Price = Demand Price (Demanders are guaranteed to pay world price + $0.0125) (Shift Effects) P M is larger than it would be in a free market ( P M *) Q is larger than it would be in a free market ( Q*) (d) Combined Effects of LDP & Step 2 P s = Supply Price = P M & (P L - P W ) P W = Demand Price = World Price (Guaranteed + $ not depicted) P M = "Market" Price, though it is neither a supply nor a demand price P M * = Free market price (Shift Effects) P S < P M, but P M vs P M * is an empirical issue 9

10 Data Market data (prices, quantities, etc ) Cotton and Wool Outlook, Cotton Council, Cotton Incorporated, BLS Macroeconomic and trade data (GDP, imports/exports) OECD, Cotton and Wool Outlook Cotton Research and Promotion Program expenditures Cotton Incorporated Farm Program data (LDP, Step 2, ) USDA 10

11 Econometric Model of US Cotton Market Market Component Dependent Variable Explanatory Variables * Raw Cotton Demand Domestic Raw Cotton Demand Exports Domestic mill use per capita U.S. exports Price of US cotton Price of substitute fibers Macro variables CI Promotion Expenditures CI Non-Ag Research Expenditures Price of US cotton Price of substitute fibers Macro variables Raw Cotton Supply Domestic U.S. cotton production * Adjustments for time lag effects and seasonality Price of cotton (futures) Lagged input price Trend 11

12 Econometric Estimation Results Model Performance Theoretical consistency Price effects as expected Domestic and foreign cotton are substitutes Export demand and import supply more elastic than domestic supply & demand Rigorously tested lag structures 12

18 Farm Program Interactions LDP program Step 2 Interaction Dampens the price effect on domestic producers Enhances the price effect on domestic producers Effect on Total ROI 20 % +55% 18

19 Summary Cotton Program has a strong and positive effect on the demand for US Cotton Returns to producers substantially outweigh the costs Interaction effects have large impact on net return to demand-side CRPP activities LDP Step 2 Target Price 19

20 Policy Implications Incentive for Establishing Research and Promotion Programs May be reduced for commodities with nonrecourse Loans/LDPs LDPs Few commodities with required support have R&P Programs Commodities that do have R&P Programs tend to have unique support Programs Commodities without required support continue to show interest in R&P 2002 Farm Bill 20
