The larger the market, the bigger the migration flow destined for it. Additionally, the gravity equation was estimated by taking into account the number of jobs per sector of primary, secondary, and tertiary economic activity. Similarly, a short and balanced panel was estimated, using the random effects model. This second version of the gravity equation 16 is presented below. In Table 3, we observe that the coefficients are statistically significant.
Adicionalmente se estimó la ecuación gravitacional considerando la cantidad de empleos por sector de actividad económica primaria, secundaria y terciaria; de forma similar se estimó un panel corto y balanceado, mediante el modelo de efectos aleatorios; esta segunda versión de la ecuación gravitacional 16, se presenta a continuación.
