                    In fact, we rely on the DPD system estimation to detect the impact of FDI and ODA
                    on government size. The long run coefficients are calculated by the equation: long
                    run  parameter  (coefficient)  =  determinant  (independent  variable)  coefficient  /  1-
                    dependent variable coefficient, Sabra, (2015).
                    DATA

                    This  article  uses  panel  data  of  seven  selected  middle  income  MENA  countries,
                    which are (Algeria, Egypt, Jordan, Lebanon, Morocco, Palestine, and Tunisia) for
                    the  period  from  2000  to  2019.  We  use  government  size,  inward  FDI  flows,
                    openness,  ODA  and  country  size  variables.  ODA  is  the  net  official  development
                    assistance and official aid received. Trade openness measured by the sum of exports
                    plus  imports  as  a  share  of  GDP.  Government  size  is  general  government  final
                    consumption expenditure as a share of GDP. Population as a proxy of country size.
                    The proxies of variables are widely used in the previous literature. All row data of
                    variables  are  collected  from  World  Development  Indicators  of  the  World  Bank,
                    except FDI inflows, which collected from UNCTAD database, besides openness and
                    government  size,  which  are  calculated  as  exports  plus  imports,  and  government
                    expenditure divided on GDP, respectively. Limited missing values are still standing.
                    All variables are taken in logarithm. We use the variables in algorithm to get the
                    elasticities, guarantee linearity and reducing any potential multicollinearity. STATA
                    software has been used for the analyses.
