Answer: This will lead to economic growth.
Explanation: First of all, from the question above, we can conclude that workers are trained already. Therefore the country will not need to pay for the education of these skilled workers.
Hence, there will be an increase in the level of human capital of the country at little or no cost.
According to Paul Romer, the new growth theory, knowledge and human capital are endogenous variables which together will positively stimulate the growth of GDP of a country.
Also, we must not forget that skilled workers will on average, take good care of their families. In addition, they are good educational practitioners and supporters and this will, in the long and short run, definitely stimulate the growth of the economy.
