Shortage

In this case, shortages may be accepted because they theoretically enable a certain portion of the population to purchase a product that they couldn't afford at the market-clearing price.

For example, a price ceiling may cause a shortage, but it will also enable a certain percentage of the population to purchase a product that they couldn't afford at market costs.

In a wider definition, a widespread domestic labour shortage is caused by excessively low salaries (relative to the domestic cost of living) and adverse working conditions (excessive workload and working hours) in low-wage industries (hospitality and leisure, education, health care, rail transportation, aviation, retail, manufacturing, food, elderly care), which collectively lead to occupational burnout and attrition of existing workers, insufficient incentives to attract the inflow supply of domestic workers, short-staffing at workplaces and further exacerbation (positive feedback) of staff shortages.

[19] Labour shortages occur broadly across multiple industries within a rapidly expanding economy, whilst labour shortages often occur within specific industries (which generally offer low salaries) even during economic periods of high unemployment.

[20] In response to domestic labour shortages, business associations such as chambers of commerce would generally lobby to governments for an increase of the inward immigration of foreign workers from countries which are less developed and have lower salaries.

[21] In addition, business associations have campaigned for greater state provision of child care, which would enable more women to re-enter the labour workforce.
