Dear Nisa,

I've employed a Data Envelope Analysis to briefly describe some evidence on growth due to the activity rate and government expenditure on education in term of the relative efficiency of PIGS economies. The paper is published on Statistika vol.93 (4), 2013.

Here you could find some useful stuff.

If you  can understand my general purpose DEA program, you can write many papers very easy.My program is coded by LINGO that can solve CCR model and inverted DEA.

It input k decision making unit by n variables as Excel cell range and output both DEA efficient values, weights and cross efficients of both model. You translate my Japanese paper by Google translation.

MODEL:

SETS:

  DMU/1..23/:SCORE,SCORE2; FACTOR/1..5/; DXF( DMU, FACTOR):  F,W,W_2;

  S40(DMU,DMU):S,S_2, TOP, BOTTOM;

ENDSETS

DATA:

  NINPUTS =3;WGTMIN = .000000;BIGM = 999999; F=@OLE( ) ;

ENDDATA

SUBMODEL CCR:

  MAX = @SUM( DMU: SCORE);

  @FOR( DMU( I): SCORE(I) = @SUM( FACTOR(J)|J #GT# NINPUTS:  F(I,J)* W(I, J));

   @SUM( FACTOR( J)| J #LE# NINPUTS:    F( I, J)* W( I, J)) = 1;

   @FOR( DMU( K):

   [LE1] @SUM( FACTOR( J)| J #GT# NINPUTS: F( K, J) * W( I, J))

          = @SUM( FACTOR( J)| J #LE# NINPUTS: F( K, J) * W_2( I, J)) ) );

  @FOR( DXF( I, J): @BND( WGTMIN, W_2, BIGM));

ENDSUBMODEL

CALC:

    @SET( 'TERSEO', 1);

    @SOLVE(CCR);

    @FOR( DMU( I): @FOR( DMU( K): 

      TOP( K, I) = @SUM( FACTOR( J)| J #GT# NINPUTS: F( K, J) * W( I, J));

      BOTTOM( K, I) = @SUM( FACTOR( J)| J #LE# NINPUTS: F( K, J) * W( I, J));

      @IFC( BOTTOM( K, I) #NE# 0: S( K, I) = TOP( K, I) / BOTTOM( K, I);

      @ELSE

         @WRITE( '  *** DIVIDE BY 0 FOR K, I = ', K, ' ', I, ' ***', @NEWLINE( 1));

         @WRITE( '  *** BOTTOM( ', K, ', ', I,') = ', BOTTOM( K, I), ' ***', @NEWLINE( 2));

         S( K, I) = 1.E30; ); ));

    @SOLU();@SET( 'TERSEO', 0);  @OLE()=SCORE,W,S;

    @SET( 'TERSEO', 1);

    @SOLVE(ICCR);

    @FOR( DMU( I): @FOR( DMU( K): 

      TOP( K, I) = @SUM( FACTOR( J)| J #GT# NINPUTS: F( K, J) * W_2( I, J));

      BOTTOM( K, I) = @SUM( FACTOR( J)| J #LE# NINPUTS: F( K, J) * W_2( I, J));

      @IFC( BOTTOM( K, I) #NE# 0:  S_2( K, I) = TOP( K, I) / BOTTOM( K, I);

      @ELSE

         @WRITE( '  *** DIVIDE BY 0 FOR K, I = ', K, ' ', I, ' ***', @NEWLINE( 1));

         @WRITE( '  *** BOTTOM( ', K, ', ', I,') = ', BOTTOM( K, I), ' ***', @NEWLINE( 2));

         S_2( K, I) = 1.E30;  );));

    @SOLU();

    @SET( 'TERSEO', 0);  @OLE()=SCORE2,W_2,S_2;

DEA is a fairly straightforward system to use. Usually one takes a series of inputs and outputs of a relatively homogeneous set of activities and assesses their relative efficiency. A straightforward paper is the initial Charnes, Cooper and Rhodes paper in the European Journal of Operational Research in 1978 but there have been thousands that explain the procedure for different industries and sectors. 

A simple introduction can be found at www.deazone.com which was set up by Dr. Ali Emrouznejad of Aston university. It is a good starting point. Links to software are there too but as demonstrated it is a fairly simple program to write if you have programming skills. if not there are many free versions out there.
