Gauss Programs Used for Estimation and Simulation

 

 

MAXDISTX.PRG

 

This program performs computations described in section 3, and generates:

 

the method of moments estimate of theta

the OLS estimates of theta (with & without constant), footnote 26

the unrestricted pure price regressions, footnote 26

the OLS estimate of theta, with source & destination dummies

the 2SLS estimate of theta with geography instruments

        

table II

the data used to plot figure II

 

Input files needed are:

trade1.fmt

getdist.dat

pppdat1.prn

 

 

SIMPRM2X.PRG

 

This program performs the non-parametric trade regressions described in section 5.1, and generates the results found in tables III, IV, and V.

 

Input files needed are:

trade1.fmt

trade2.fmt

 

 

SOURCRGX.PRG

 

This program generates the results given in section 5.4, and generates tables VI and VII.

 

Input files needed are:

datafe.fmt

trade1.fmt

trade2.fmt

trade3.fmt

 

 

EQUILX.PRG

 

This program computes equilibrium as described in section 4.  It is used as the baseline from which the counterfactuals described in section 6.1 and 6.3 are computed using SIMULX.PRG, and from which the counterfactuals described in section 6.4 are computed using SIMLTARX.PRG

 

Input files needed are:

datafe.fmt

trade2.fmt

 

SIMULX.PRG

 

This program takes as input the baseline computed by EQUILX.PRG, and performs one or more experiments to generate the counterfactuals described in section 6, and generates tables VIII and IX.

 

Input files needed are:

basefe.fmt (generated by EQUILX.PRG)

datafe.fmt

trade2.fmt

 

 

SIMLTARX.PRG

 

This program takes as input the baseline computed by EQUILX.PRG, and performs a tariff-reduction experiment to generate the results described in section 6.4 and generates table XII

 

Input files needed are:

basefe.fmt (generated by EQUILX.PRG)

datafe.fmt

trade2.fmt
