Matthew T. Holt and Andrew M. McKenzie, "Quasi-Rational and Ex Ante Price Expectations in Commodity Supply Models: An Empirical Analysis of the U.S. Broiler Market", Journal of Applied Econometrics, Vol. 18, No. 4, 2003, pp. 407-426. The bi-monthly time series data that were used in this study are contained in the file broiled3.dat, an ASCII file in DOS format that is zipped in the file hmquasi.zip. Also included in the hmquasi.zip file is the file broild3.for, also in DOS format, that contains the basic FORTRAN code used, in conjunction with GQOPT, to estimate the parameters of the preferred model. The data contained in broild3.dat consist of 177 bi-monthly observations starting with the third bi-monthly period in 1966 and ending with the fifth bi-monthly period in 1995. There are 21 variables. With the exception of dummy variables and the year/bi-month indicator, all variables represent natural logarithms, multiplied by 100. In estimation the first ten and the last two observations are omitted to initialize data lags and leads. The data set broild3.dat is organized according to the list below. Column Series 1. year/bimonth (i.e., 6702 is the first bi-month of 1967, etc.) 2. cattle futures price 3. cattle spot price 4. hog futures price 5. hog spot price 6. corn futures price 7. corn spot price 8. soybean meal futures price 9. soybean meal spot price 10. iced broiler futures price 11. twelve-city broiler wholesale price 12. Georgia dock wholesale broiler price 13. dummy variable for bi-month one 14. dummy variable for bi-month two 15. dummy variable for bi-month three 16. dummy variable for bi-month four 17. dummy variable for bi-month five 18. hatch of broiler type chicks 19. young chicken, ready to cook production 20. turkey spot price 21. linear time trend The feed cost variable used in the model is constructed according to the formula fc=ln(70*cs/56)+(30.*sms/20))*100, where cs denotes the corn spot price and sms the soybean meal spot price. Additional details regarding the data may be found in section 3 of the article. Matthew T.
