Finally, in a more recent study, Fries and Taci (2005) examine the cost efficiency in 15 post-communist countries. The results indicate that privatized banks with majority foreign ownership are the most cost efficient ones and those with domestic ownership are the least, though both being more efficient than state-owned banks. 3. Determinants and variable selection 3.1. Dependent variable
This study uses return on average assets (ROAA) to evaluate bank's performance. ROAA is the net profits expressed as a percentage of average total assets. It shows the profits earned per euro of assets and indicates how effectively the bank's assets are being managed to generate revenues. Average assets are being used in order to capture any differences that occurred in assets during the fiscal year. As Golin (2001) points out, return on average assets is the key measure of profitability. 3.2. Determinants and independent variables
Four bank characteristics are used as internal determinants of performance. These are the bank's total assets, the cost to income ratio, the ratio of equity to assets and the ratio of bank's loans divided by customers and short term funding. In addition, six external determinants are used to examine the impact of environment on bank's performance (Table 1).

The ratio stock market capitalization to total assets of the deposit money banks.a This variable serves as a proxy of financial

The ratio stock market capitalization to GDP. It measures the overall
MACGDP level of development of the market and its importance in financing the
economy (in constant US$ 1995)
Notes: the data for the calculation of internal factors and CONC were obtained from Bankscope Database. The data for the external factors were obtained from Euromonitor International Database which uses sources such as International Monetary Fund's (IMF) International Financial Statistics (IFS), World Economic Outlook/UN/National Statistics and World Bank.
The ratio of equity to assets (EQAS) is used as a measure of capital strength. Generally speaking, banks with high capital-asset ratios are considered relatively safer in the event of loss or liquidation. Therefore, the conventional risk¨Creturn hypothesis would imply a negative relationship between equity to assets ratio and bank performance. However, the lower risk increases banks creditworthiness and consequently reduces the cost of funding. At the same time, banks with higher equity to assets ratio will normally have lower needs of external funding and therefore higher profitability.
Another basic policy of commercial banks refers to their liquidity management and specifically the process of managing assets and cash flow to maintain the ability to meet current liabilities as they come due. Without the required liquidity and funding to meet obligations, a bank may quickly fail, or at least be technically insolvent. The ratio of net loans to customers and short term funding (LOFUND) is used to measure the relationship between liquidity management and performance. This ratio shows the relationship between comparatively illiquid assets (i.e. loans) and comparatively stable funding sources (i.e. deposits and other short term funding). Therefore, the lower the value of this ratio, the more liquid the bank is. Since liquid assets are associated with lower rates of return a positive relationship is expected between this variable and performance.
The cost to income ratio (COST) is used to measure the impact of efficiency in expenses management on banks performance. This ratio shows the costs of running the bank, the major element of which is staff salaries and benefits, and is expected to have a negative relationship with bank's performance.
Bank's size (SIZE) is considered an important determinant of its performance. The reason is that large size may result in economies of scale that will reduce the cost of gathering and processing information (Boyd and Runkle, 1993). As in most studies in
Variables
ÒøÐÐÓ¯ÀûÄÜÁ¦·ÖÎöÖÐÓ¢ÎĶÔÕÕÍâÎÄ·ÒëÎÄÏ×
banking, we use total assets of the bank as a proxy for its size to account for size related economies or diseconomies of scale.
Turning to the external determinants, two sets of variables have been considered in this study, indicating macroeconomic conditions and financial structure characteristics. The two macroeconomic variables used are gross domestic product growth (GDPGR) and inflation (INF).
GDP is among the most commonly used macroeconomic indicators and it is a measure of total economic activity within an economy. The real GDP growth, used in this study, is expected to have a positive impact on bank's performance according to the well-documented literature on the association between economic growth and financial sector performance.
The relationship between inflation and banks performance depends on whether the inflation is anticipated or unanticipated (Perry, 1992). In the first case (i.e. anticipated inflation) banks can timely adjust interest rates, which consequently results in revenues that increase faster than costs, with a positive impact on profitability. In the second case (i.e. unanticipated inflation) banks may be slow in adjusting their interest rates resulting in a faster increase of bank costs than banks revenues. This will consequently have a negative impact on bank profitability.
We finally examine how the performance of banks is related to the relative development of the banking industry and the stock market using the ratios stock market capitalization to GDP (MACGDP), stock market capitalization to total assets of deposit money banks (MACPASS), total assets of deposit money banks to GDP (ASSGDP) and banking industry concentration (CONC). MACPASS reflects the complementarity or substitutability between bank and stock market financing, while ASSGDP and MACGDP measure the overall level of development of the banking sector and the stock market, respectively as well as their importance in financing the economy. Concentration is the proportion of an industry's total assets controlled by its largest firms. According to the structure-conduct performance (SCP) hypothesis, banks in highly concentrated markets tend to collude and therefore earn monopoly profits (Short, 1979, Gilbert, 1984 and Molyneux et al., 1996). Collusion may result in higher rates being charged on loans, less interest rates being paid on deposits and so on (Goddard et al., 2001). CONC is calculated as the total assets held by the five largest commercial banks in the country divided by the total assets of all commercial banks in the country.
