Medan is the third largest city in Indonesia by population. It is sometimes known as the city of a million shop-houses as many people start small firms at the street level of their homes. This has led to an increase in the market supply of industries such as cafes and clothes shops. Also, due to the growth in demand for food delivery, the unemployment rate has fallen. However, mobility of labour is limited both within Medan and within Indonesia.

Droughts in the Pacific Coast region of the US and regulations, in the form of limits on the amount of salmon that can be caught in the wild, have reduced the supply of wild salmon. These limits were imposed to avoid market failure in the salmon market. However, the effect of this on the revenue of salmon producers is uncertain. In addition, producers of farmed salmon in the US states of Washington and Alaska have received subsidies from the US government.
