There are three ADCII text files, which are zipped in the file
gvb-files.zip. These files are in DOS format, so Unix/Linux users
should use "unzip -a".

synth-panel.txt: This file contains the data for the empirical
application of the Sierra Leone and Arab-Israeli wars.

simulation-DGP.R: This file includes the code used to generate the
simulation data. It uses an auxiliary data file for part of the DGP,
called rgdpl1980.txt.

Users should refer to the supporting information from Cheng Hsiao, H.

Integration of Hong Kong with Mainland China", Journal of Applied
Econometrics, Vol. 27, No. 5, 2012, pp. 705-740 at the following web

data used in the empirical application of the Political and Economic
Integration of Hong Kong

The data used for the empirical application of the Sierra Leone and
Arab-Israeli wars consists of a panel data, in long format, with 41
countries:

 [1] Albania    
 [2] Australia  
 [3] Austria    
 [4] Bahrain    
 [5] Barbados   
 [6] Belgium    
 [7] Belize     
 [8] Benin      
 [9] Botswana   
[10] Brazil     
[11] Brunei     
[12] Bulgaria   
[13] Canada     
[14] Denmark    
[15] Fiji       
[16] Finland    
[17] Germany    
[18] Guyana     
[19] Iceland    
[20] Ireland    
[21] Israel     
[22] Italy      
[23] Jamaica    
[24] Japan      
[25] Jordan     
[26] Luxembourg 
[27] Malawi     
[28] Maldives   
[29] Malta      
[30] Mauritius  
[31] Mongolia   
[32] Namibia    
[33] Norway     
[34] Poland     
[35] SierraLeone
[36] Singapore  
[37] Swaziland  
[38] Sweden     
[39] Switzerland
[40] Tonga      
[41] Zambia 

The only variable we used is the log of real GDP per capita, Laspeyres
index, from the Penn World Table 7.0. The time series observations for
each country range from the year 1957 to the year 2009.

For the Sierra Leone civil war application, we use the annual log real
GDP per capita from 1970 to 2009. For the Arab-Israeli war
application, we use the annual log real GDP per capita from 1957 to
1975. For each of the two cases we use all the the countries that have
data available for them.

The file simulation-DGP.R includes R code used to generate data for
both simulations. This file shows how the different DGPs of the
two simulations explained in the paper are generated. For each of the
10,000 iterations used in the simulations, one simulated dataset is
generated. The file uses an auxiliary data file, rgdpl1980.txt, for
the individual effects and the covariate part of the DGP. This
auxiliary data file, rgdpl1980.txt, consists of the log of real GDP
per capita, Laspeyres index, from the Penn World Table 7.0, for the
year 1980 for 157 countries.
