Additionally, assume there is a cost C associated with migrating from country 0 to country 1 and workers know all parameters and their own realization of e 0 and e 1. Borjas then uses the implications of the Roy model to infer something about what wages for immigrants in country 1 would have been had they stayed in country 0 and what wages for ...

For proportional transaction costs the problem was solved by Davis and Norman in 1990. [6] It is one of the few cases of stochastic singular control where the solution is known. For a graphical representation, the amount invested in each of the two assets can be plotted on the x - and y -axes; three diagonal lines through the origin can be ...
The Extended cost-loss model [9] [10] [11] is a simple extension of the cost-loss model. While the cost-loss model analyses the question "Should I take precautionary action now?" the extended cost-loss model analyses the question "Should I take precautionary action now or should I wait for the next forecast before deciding whether to take ...

The theorem assumes that there are two goods and two factors of ...
