This research will follow the methodology of econometrics; Chao, 2005; Castle & Shephard, 2009):
1. Specification of the model using a specific stochastic equation, together with a priori theoretical expectations about the sign and size of the parameters of the function.
2. Data collection on the variables of the model and estimation of the coefficients of the function using appropriate econometric techniques.
3. Evaluation of the estimated coefficients of the function based on economic statistical and econometric criteria.
The study will follow the econometric procedure to analyze the relationship between FDI, imports and exports, and respective equations. For bivariate models related to FDI and imports and FDI and exports, the model will investigate relationships following the equations:
( 19) (20) (21) EXP = βn + βn+1 INV + u,
where EXP is exports from the technology sector, INV is Foreign Direct Investment or Domestic Investment to the technology sector, βn the unknown constant parameter, parameter βn+1 is the slope coefficient, and u is the random disturbance, error, or stochastic term.
(22) (23) (24) IMP = βn - βn+1 INV + u,
where IMP is imports from the technology sector, INV is Foreign Direct Investment or Domestic Investment to the technology sector, βn the unknown constant parameter, parameter βn+1 is the slope coefficient, and u is the random disturbance, error, or stochastic term.
For multivariate models related to FDI and imports and FDI and exports, the model will investigate relationships following the equations:
(25) EXP = βn + βn+1 INV. + βn+2INVN-U.S. + βn+3 INV + u,
where EXP is exports from the technology sector, INV is investment to the technology sector and βn, βn+1, βn+2, and βn+3 are the unknown constant parameters. The parameters βn+1, βn+2, and βn+3 are the slope coefficients, and u is the random disturbance, error, or stochastic term.
(26) IMP= βn + βn+1 INV - βn+2INV - βn+3 INV + u,
where IMP is imports from the technology sector, INV is investment to the technology sector, and βn, βn+1, βn+2, and βn+3 β1, β2, β3 and β4 are the unknown constant parameters. The parameters βn+1, βn+2, and βn+3 are the slope coefficients, and u is the random disturbance, error, or stochastic term.
