	Obs:   52 annual observations, 1950-2001

	Q		per-capita consumption of chicken, pounds, boneless equivalent (USDA data system)
	Y		per-capita real disposable income, chain-linked prices, 1996 = 100 (BEA)
	PCHICK 		CPI index for whole fresh chicken, 1982-1984 = 100 (Bureau of Labor Statistics)
	PBEEF		CPI index for beef, 1982-84 = 100 (Bureau of Labor Statistics)
	PCOR		PPI index for corn, 1982 = 100 (Bureau of Labor Statistics)
	PF		nominal price index for broiler feed, scaled to imply 1982-84 = 100 (USDA, Poultry Yearbook, 2000)
	CPI 		Consumer price index, 1982-84 = 100 (Bureau of Labor Statistics)
	QPRODA		Aggregate production of young chicken, pounds (USDA, Poultry Yearbook,2000)
	POP		U.S. population on July 1, resident plus armed forces, millions (Bureau of Labor Statistics)
	MEATEX		exports of beef, veal, and pork, pounds (USDA)
	TIME		as used in regressions (TIME = 0 for 1909, TIME = 1 for 1910)

Note 1: real variables constructed as:

	PC = PCHICK/CPI
	PB = PBEEF/CPI

Note 2: Capitalized variables are not logarithms.
	These data are from Dennis Epple and Bennett T. McCallum (2006)	"Simultaneous Equation Econometrics: The Missing Example," 
Economic Inquiry, 44(2), 374-384.
	
Note 3: To reproduce the results in their paper, QPRODA must be divided by 1439. This conversion factor transforms gross
production of chicken into the boneless equivalent that is used as the consumption variable.

The authors would like to acknowledge the generous help of Bennett McCallum.
