1975-1987:  An Application of a Modified Symmetric Generalized McFadden
Cost Function", Journal of Applied Econometrics, Vol. 10, No. 3, 1995, 
pp. 221-232.

The ascii file "rask.dat" (which is zipped in rask.zip) contains the
data used to estimate the symmetric generalized McFadden cost function
for sugarcane production in Brazil.  The data are written one
observation per line, with a space acting as the delimiter.  Missing
values are contained in the line for forncedores in 1977, and are
identified by a dot (".").  Therefore there are 130 observations for the
general variables like year and state.  However, all the information on
prices and quantities has 125 observations, (13 years, 5 states, 2 types
of producers per state, minus the missing year 1977 for the fornecedores
in each state.)  The 36 variables were written by PC-SAS V. 6.04 in the
following order:  (The longest record length is about 370 characters so
if you need a "lrecl" statement to read it in using lrecl=400 should
work.)

Year = Date of Surveyed Costs, between 1975 and 1987.
State = 1=Sao Paulo, 2=Minas Gerais, 3=Rio de Janeiro, 4=Pernambuco, 5=Alagoas
Plab = Divisia Price Index for Labor
Pchem = Divisia Price Index for Chemicals
Pmach = Divisia Price Index for Machinery
Qlab = State total quantity of labor in man-hours.
Qchem = State total quantity of chemicals in tons.
Qmach = State total quantity of machinery in hours.
Sum = (theta sub l)*Plab + (theta sub c)*Pchem + (theta sub m)*Pmach
LYinv = Qlab/Y
CYinv = Qchem/Y
MYinv = Qmach/Y
Plsum = Plab/Sum
Pcsum = Pchem/Sum
Pmsum = Pmach/Sum
Thcpc2 = ((1/2)*(theta sub c)*Pchem*Pchem)/(sum**2)
Thcpl2 = ((1/2)*(theta sub c)*Plab*Plab)/(sum**2)
Thcpm2 = ((1/2)*(theta sub c)*Pmach*Pmach)/(sum**2)
Thlpc2 = ((1/2)*(theta sub l)*Pchem*Pchem)/(sum**2)
Thlpl2 = ((1/2)*(theta sub l)*Plab*Plab)/(sum**2)
Thlpm2 = ((1/2)*(theta sub l)*Pmach*Pmach)/(sum**2)
Thmpc2 = ((1/2)*(theta sub m)*Pchem*Pchem)/(sum**2)
Thmpl2 = ((1/2)*(theta sub m)*Plab*Plab)/(sum**2)
Thmpm2 = ((1/2)*(theta sub m)*Pmach*Pmach)/(sum**2)
Thcpcpm = ((theta sub c)*Pchem*Pmach)/(sum**2)
Thcplpc = ((theta sub c)*Plab*Pchem)/(sum**2)
Thcplpm = ((theta sub c)*Plab*Pmach)/(sum**2)
Thlpcpm = ((theta sub l)*Pchem*Pmach)/(sum**2)
Thlplpc = ((theta sub l)*Plab*Pchem)/(sum**2)
Thlplpm = ((theta sub l)*Plab*Pmach)/(sum**2)
Thmpcpm = ((theta sub m)*Pchem*Pmach)/(sum**2)
Thmplpc = ((theta sub m)*Plab*Pchem)/(sum**2)
Thmplpm = ((theta sub m)*Plab*Pmach)/(sum**2)
Y = Total sugarcane output in tons.
H = Total hectares in production.
K = Total fixed-capital in $Cz.
