The data used in this paper are provided in two files: data for conventional
banks are in the file conven.txt, and data for Islamic banks (special finance
houses) are in the file islamic.txt. Both files are zipped in the file
bankdata.zip.

The dataset for conventional banks is an unbalanced panel of 526 timeseries
observations for 49 conventional banks. The dataset for Islamic banks is an
unbalanced panel of 43 timeseries observations for 4 Islamic banks.  Both
datasets are stacked sets of time series, i.e. the first 11 observations are
a timeseries for the first bank and so on.  Missing values are denoted by
a period (.).

The data are in plain ASCII text files in DOS format. Data are organized in
columns separated by tabs.  The variables in both files are identically
labeled except that Islamic.txt does not have the TS variable.  Each file
contains the variables in the following order:

i t P1 P2 P3 y C EE NE FAE FA TIE BF D ND NPL EC q r TA TS

Where

i	= bank i.d. (1 to 53)
t	= years (1 to 11)
P1	= Price of Labor
P2	= Price of Borrowed Funds
P3	= Price of Physical Capital
y	= Output: Total Loans
C	= Total Cost
EE	= Employee Expenses
NE	= Number of Employees
FAE	= Fixed Assets Expenses
FA	= Fixed Assets
TIE	= Total Interest Expenses (Interest on deposits and non-deposit funds 
          + Other interest expenses) 
BF	= Borrowed Funds (Deposits + Non-Deposit Funds) 
D	= Deposits
ND	= Non-Deposits
NPL	= Non Performing Loans
EC	= Equity Capital
q	= Quality Index
r	= Risk Index
TA	= Total Assets
TS	= Total Securities (only for conventional banks)

Original data were expressed in nominal Turkish Liras. We converted the data
to real terms using the Turkish Consumer Price Index (CPI), with 1995 as the
base year. We then converted all of the variables to real 1995 USD using the
real exchange rate for 1995, which is the base year for Turkish and U.S.
CPIs.  Please note that the paper uses logarithmic values in the estimation.
