Relevance, Impact and Challenges
By presenting several econometrical models and taking into account historical and social gender focused behaviors, the author analyzes the impact of part-time employment on earning disparities, labour market segmentation and the probability of being promoted to a higher level of responsibility. While introducing ways to improve the situation for part-timers, the author examines innovative models of work organization such as job-sharing, top-sharing, functional flexibility and project team rotations. Beyond demonstrating the need for changes within public and private companies, the book also reveals concrete instruments on policy which could facilitate the implementation of such innovative models.

93 4. Earnings inequalities between full- and part-time employees 4.1 Introduction Working part-time is not only synonymous of giving up advanced career opportunities and accepting more repetitive tasks where education and skills are less required to respond to the needs of employers. Working on flexible schedule can also have an impact on earnings. In other words, part-timers can also be affected by some earnings disparities in compari- son to what they would earn if they worked full-time. This difference in remuneration can be measured on a salary per hour basis. Considering the current existing statistics in the Swiss labour mar- ket, this chapter aims to analyze with more accuracy the hypothesis of earning inequalities between part-time and full-time workers. To analyze this assumption, a first empirical analysis is developed through a stand- ard earning linear regression with several characteristics. For compari- son we also test a similar correlation through a probit model. The vari- able part-time is, in this context, highly disaggregated and considered as an explanatory42 variable of the models. In a second stage, we again define two groups of employees (full- timers and part-timers) and present an empirical model based on the Oaxaca Blinder methodology of wage decomposition to directly investi- gate how much of the differential between our two defined samples is based on differences in endowments (characteristics) and on differences in treatment (valuation of the endowments) by employers. To obtain better results and tools of comparison, two official datasets are used in following econometrical models: first,...
