Effects of Financial Capital on Colombian Banking Efficiency
Abstract |
| In this paper we discuss cost and profit
efficiency for a sample of financial institutions on the Colombian financial market in the
period 1989-2003, using stochastic frontier efficiency analysis. During the period, the
cost efficient frontier deteriorates, but profit efficient frontier is relatively stable.
We found significant difference when we compare the efficiency scores between types of
financial intermediaries. Additionally, our analysis show that the scores for profit and
cost efficiency have different distribution. We found big differences between profit and
cost efficiency among the different type banks. This is evidence in favor of some banks
behaving collusively and capturing oligopoly rents.
