Introduction Introduction Technical Efficiency It is defined as the production of a desired level of
output with the minimum amounts of inputs.
Technical efficiency whether a productive unit is
efficient relative to others whether a firm is
efficient. Typical business entity can be considered as
technically
efficient relative to its competitors
IntroductionIntroductionDEA – Data Envelopment Analysis
offers an empirical approach to the efficient frontier for a collection of firms through an assessment of their individual performances.
DEA – A tool for efficiency a particularly powerful tool for assessing operational
efficiency in
service organizations.
DEA – A subject a subject of extensive theoretical refinements and empirical applications.
ModelModelStandard DEA Model
The efficiency an arbitrary bank i (i = 1,…,k) is defined as follows:
Hi = (Weighted sum of bank i’s outputs) / (Weighted sum of bank i’s inputs)
=
ModelModelQuestion:
How to perfect the substitutability among outputs and inputs?
-- Standard optimization
Empirical ResultsEmpirical ResultsTable 1: The 2007 Data for 26 Turkish Banks
Table 2: The 2010 Data for 26 Turkish Banks
Table 3: Log (outputs) and Log (inputs) and the DEA efficiency for 26 Turkish commercial banks in 2007
Table 4: Log (outputs) and Log (inputs) and the DEA efficiency for 26 Turkish commercial banks in 2010
Table 5: Efficiencies Comparison Pre and Post Recession
ConclusionConclusionUsing a modified version of the standard
DEA for a sample of 26 major Turkish Banks for 2007 and 2010
First, the prevalence of substantial inefficiencies amount the Turkish banks
Second, Obtained essentially similar results with even show a more dramatic decline in recent bank efficiency in Turkey.
