A more promising direction is the one taken by Van Ours and Ridder (1992), who tried to achieve representative results in their study of the duration of vacancies in order to determine aspects of employers' search strategy by selecting a 5% random sample from all establishments in the Netherlands.
21 We used a friction period of 115 days, that is, the average duration of vacancies (87 days) increased with the expected number of weeks employers need before taking the decision to place a vacancy for temporary or permanent replacement of the worker (28 days).
In that case, we can disregard congestion externalities as the elasticity of the expected duration of a vacancy is equal to the bargaining power of workers in a symmetric Nash bargaining situation.8.8
For simplicity, we here let ({y_{l}^{F}}={y_{l}^{I}},;l={h,m}.) Moreover, as the Hosios condition holds by assumption, as we have assumed that the elasticity of the expected duration of a vacancy is equal to the bargaining power of workers in a Nash bargaining situation, we can disregard congestion externalities on the labour market.
While laudable in scope, we question whether "permanent" solutions are appropriate given the widely varying causes, durations, contexts and patterns of vacancy and the inability of similarly scoped government-led programs to thus far achieve intended goals or improve local quality of life.
However, the findings suggest that the effectiveness of vacancy referrals does not depend on the elapsed unemployment duration, neither on the age nor on the gender of the participants.
There was plenty of vacancy.
"That is an enormous amount of vacancy".
I can have an air of vacancy about me.
The building has 300,000 square feet of vacancy.
