Answer:
Let the price of labor increase.
Step-by-step explanation:
An unregulated market is also termed as a free market economy. Here, the government does not interfere in the business of supply and demand. Resources are determine by the authority without any government intervention.
In order to cure the labor shortage in an unregulated market when there is no immigrants for labor supply, the prices of the labor may be increased. In doing so it will affect the supply and demand of labor. As the labor price will increase, the supply of labor will also increase as now more and more labor wants to work in order to get a high wage.
So increasing the price of the labor will cure for the labor shortage.
