The Farm Animal Welfare Debate: Where We Have Been Section A
John Steinbeck in Travels With Charley Even while I protest the assembly-line production of our food, our songs, our language, and eventually our souls, I know that it was a rare home that baked good bread in the old days.Page 83. 1962 Section A
But what about the animals? Section A
The Farm Animal Welfare Debate: Where We Are Going Section A
The Farm Animal Welfare Debate: What Makes Chickens Happy? • Determinants of Hen Welfare • Space per hen • Barn space per hen • Beak trimming • Room for scratching • Nest availability • Free-range access • Group size Section A
The Farm Animal Welfare Debate: An Interesting Question Is this worth $0.60 more per dozen? Let us ask consumers. Especially informed consumers. Section A
Conventional Valuation: Overview Estimate some regression: Bid = a0 + a1(X) e.g. indicate your auction bid Section B
We want to measure individual values for 41 attribute levels. Section B
We want to measure individual values for 41 attribute levels. • But this is impossible to do using standard valuation methods. • Is each person going to submit 41 bids? • We wish to avoid the use of random parameter logit models. • We need a system that helps respondents behave rationally. • Respondents cannot “keep their thoughts” straight when perusing goods with 41 possible attributes/attribute levels. • Want to avoid preference reversals, excessive-choice effects. Section B
Choice Experiments Are No Better Imagine Choosing Between Good A and Good B More Than 100 Times Section B
Solution: A Calibrated Auction-Conjoint Method Step 4 Submit bids Step 1 Rate the desirability of many attribute levels Utility Function auction bids Step 2 Rate the relative attributes Step 3 Calibrate utility function to generate desirable bids Section B
Step 1: Rate the Desirability of Each Attribute Level (3-3)/(9-3) = 0.00 (4-3)/(9-3) = 0.17 (9-3)/(9-3) = 1.00 Section B
Step 2: Indicate the Relative Importance of Each Attribute Section B
Describe Five Egg Production Systems Section B
Four Egg Production Systems Barn System Cage System Section B Aviary w/ Free-Range System Aviary System
Step 3: Calibrate Utility Function Step 4: Submit Bids Section B
We ask subjects to construct their own utility function, and verify it with a real auction Utility (ignoring price) = (Points to Attribute)(Rating of Attribute Level) Utility of Cage Eggs = (Points to Space)(Rating of 48 sq in) + (Points to Free-Range)(Rating of no access) = (25)(0) + (10)(0.25) = 2.5 Utility of Cage-Free Eggs = (Points to Space)(Rating of 150 sq in) + (Points to Free-Range)(Rating of access/protection) (25)(1) + (10)(1) = 35 Auction Bid for Cage Eggs = $1 Bid Premium for Cage-Free Eggs is then (utility difference) / (Points to Price) = (35 – 2.5) / 65 = 0.5 Bid Cage Eggs = $1 Bid Cage-Free Eggs = $1.5 Section B
Advantages of Calibrated Conjoint Auction Method • Low computational burden (when using computers) • Induces rationality (preference reversals impossible) • Can compute bids for any combination of attribute values, not just those in the auction • Can analyze large numbers of attributes and attribute levels • Observe individual-level behavior directly • Did you notice there is no error term? Section B
Application Locations: Dallas, Chicago, and Wilmington, NC Subjects: 300 total, in 25 person sessions Good: 150 in eggs, 150 in hog Information: objective description of farm production practices and animal welfare factors Auction: 5 egg or pork products, real BDM auction Section C
Application Is this worth $0.60 more per dozen? Let us ask consumers. Especially informed consumers. Section C
