I have the following estimation of a two-way fixed effects model:
$FDI=\beta_0+ \beta_1GDP_{gr}+ \beta_2Infl+ \beta_3Realinc + \beta_4Open+ \beta_5Reserve+ \beta_6Pol_r + \beta_7Infr+ \beta_8Nat_{re}+ \beta_9SACUit+\mu_i+\gamma_i+\epsilon_{it}$
Where FDI is measured as net inflows of foreign direct investments (% of GDP), Open is the openness of a country measured as $\frac{(imports+exports)}{GDP}$, and $GDP_{gr}$ is GDP growth (annual %).
How do I interpret the magnitude of the coefficient of the explanatory variabel Open? How do I interpret the magnitude of the coefficient of the explanatory variabel $GDP_{gr}$?
I get the following significant coefficients: Open 24.20 and $GDP_{gr}$ 0.209 Are they reasonably?
