Health worker static labor market theoretical framework. Legend: Demand (D) and supply (S) interact to determine the number of workers (H*) that will be employed at a market wage rate (W*). At a wage rate (WL) that is lower than the market optimum (W*), a shortage of workers results, and the number of workers demanded (HD) exceeds the number supplied (HS). To alleviate shortages in this market, either (1) additional compensation could be given to increase wages to W* and attract more workers into the market, or (2) the production of workers could be increased such that supply shifts outward (S2) and the quantity demand (HD) is achieved while keeping wages at WL
