Differences in the dynamics of women's and men's employment also appear to be less pronounced when exchange rates are kept at a competitive level. When demand for labour grows slowly relative to supply, levels of open unemployment increase, informal employment expands and other atypical and non-standard forms of work—such as part-time work, short-term hires and day labour markets— proliferate. At the same time, bargaining power shifts in favour of employers and the owners of firms. A reduced share of public sector jobs in overall employment reinforces this trend.
