    The Effects of Financial Structure on Life Expectancy (Cup-FM Approach) by Amirali Farhang

    Published 2022-07-01
    “…This method calculates the coefficient vector coefficients by estimating the parameters and the long-term covariance matrix and the factor loads in reverse. This estimator, like the FMOLS estimator, is resistant to successive autocorrelation bias and endogenous bias, and in addition, is indifferent to the meaning and anonymity of the explanatory variables.In this study, based on research experiences to investigate the effects of financial structure on life expectancy, the regression model used in Chireshe (2018) research has been modeled, so the model used in the leading research is as follows:Where LEit is life expectancy at birth, FSit is a variable of financial structure (loans to the private sector by the banking system as a percentage of GDP), Eit is energy consumption (kg equivalent of crude oil), PGDPit is GDP per capita and HEXPit  is health expenditure ( Percent of GDP). …”
