If NAFTA made this deal, people would be able to move easily within Canada, the United States and Mexico. Unskilled workers from Mexico would migrate to “El Norte” in search of better-paying jobs. The supply of workers in Mexico will decrease significantly. Only the terminally ignorant, or those with families in Mexico, would stay in a poor country and earn low wages. On the other hand, the supply of workers in the United States will increase significantly. The supply of workers in Canada would not be radically changed, as it is very similar to that of the United States, but further away. The number of workers moving from Canada to the United States and vice versa would not be seriously affected. However, if the supply of workers in the United States becomes too great, workers could then migrate north to Canada to find work. Secondary economics teachers would be able to work in any of the three countries, as the same basic knowledge of economics is required. I think Mexican teachers would choose to move to the United States or Canada if they were proficient in the native language because the salaries would be much more rewarding. The number of economics professors in the United States and Canada would increase, which would decrease salaries slightly. The supply of economics professors in Mexico would decrease, so economics professor salaries would increase slightly. Equilibrium salaries for economics professors will remain roughly the same and employment will be high. For carpenters, again, I think the salaries in the North would be higher. Since carpentry does not require extensive training and focuses on the talent and skills of carpenters, workers could easily relocate to another country. If all the carpenters in Mexico decide to "run for the border", the number of carpenters in the United States and Canada will increase significantly. Salaries for skilled carpenters will increase in Mexico and salaries in the United States and Canada will decrease slightly. If too many Mexicans migrate north, unemployment will be high because we will have a ton of skilled workers and not enough jobs to meet their needs. People will eventually want to return to Mexico because the supply of skilled workers is so low, wages will be slightly higher. For obstetrician-gynecologists, I think the United States or Canada would be the destination of choice, simply because our health care is much more advanced.
