Elevator pitch
Public sector jobs are created because governments opt to provide goods and services produced directly by public employees. Governments, however, may also choose to regulate the size of the public sector in order to stabilize targeted national employment levels. However, economic research suggests that these effects are uncertain and critically depend on how public wages are determined. Rigid public sector wages lead to perverse effects on private employment, while flexible public wages lead to a stabilizing effect. Public employment also has important productivity and redistributive effects.
Key findings
Pros
Expanding public sector employment can be an effective means of reducing unemployment in the short term, providing a stabilizing effect during recessions or in relatively disadvantaged regions.
Public sector employment can create demand in other sectors of the economy (e.g. private services).
Public sector employment supports equitable policies, such as encouraging employment of marginalized and/or disadvantaged groups.
Cons
Reducing short-term unemployment through expanding public sector employment can only occur when wages in the public sector are flexible according to productivity, rather than fixed.
The expansion of public sector jobs leads to “crowding out” of private sector employment; when wages are relatively unresponsive to productivity differences, this can even increase unemployment.
High public sector employment may lower overall productivity in an economy that is reallocating resources from the private to the public sector, or from higher to lower productive sectors.
