We'll be focusing on the standard, involuntary form of slavery. D. Wherever slavery has existed, there have typically been slave markets, where slaves could be bought and sold like any other commodity. But while this simple story is correct, there is more we can say about both sides of the market. In many slave systems, there have been entire industries of slave hunters who reduce people to slavery by conquest, then ship them to slave markets. As the price of slaves rises, the incentive to hunt slaves intensifies.
Hunters become more willing to transport slaves over long distances.
As the price of slaves falls, hunting efforts slacken. In most slave societies, the child of a slave is automatically a slave as well. E. This gives slave-owners some incentive to allow or even encourage slaves to have children. In some slave systems, birth rates of slaves were so low that only continuous imports of new, captured slaves made the system sustainable. This was the case in some Caribbean countries.
