Minimum hours constraints and labour supply of older workers

realization time: 08.2022 – 07.2024

The aim of the project is to understand the main reasons why firms require employees to work full-time and to quantify impact of this constraint on the total labour supply of older workers.

Older workers have a relatively high preference for part-time employment. However, many of them are overemployed, that is, they work more hours than they would prefer to. Some of the overemployed workers decide to exit the labour market. The employees’ inability to reduce their working hours is explained by restrictions imposed by the employers (a so-called minimum hours constraint).

Understanding the causes and the effects of minimum hours constraints will help to shape part-time employment regulations, taking into account their impact on businesses.
