Unemployment insurance (UI) protects workers against the risk of lost earnings during a spell of unemployment, but a more generous system can also weaken the incentive to search for and accept a new job. The generosity of most UI systems is governed by two parameters: the level of benefits relative to previous earnings, and the potential benefit duration. Unemployment insurance systems are implemented widely in European Union countries, but the specific eligibility requirements and durations vary.
Within the French UI system from 2000 to 2002, benefit durations were determined by four categories of previous employment length. Le Barbanchon (2016) uses a sharp regression discontinuity to estimate the effect of additional benefits on relatively low-employability workers by focusing on the cutoff between the two intermediate categories.
Le Barbanchon et al. (2024) draw upon the estimates from Le Barbanchon (2016) to compute the MVPF of a marginal change to UI benefit duration in France for workers at the 8 month employment history cutoff, whose benefit durations rose from 7 to 15 months. The calculation uses Schmieder and Von Wachter (2016) for a measure of the fiscal externality induced by the policy.
MVPF = 0.6
The net cost is estimated as $1 of additional UI benefit plus the fiscal externalities from reduced search effort for a new job. Reduced search effort means people will be covered by UI for longer, leading to more total UI payouts. In addition, longer periods of non-employment lead to a fiscal externality through reduced income taxes.
The paper uses a calculation from Schmieder and Von Wachter (2016) to get a fiscal externality of $1.35 and a net government cost of $2.35.
The willingness to pay for $1 of additional UI benefits is estimated as
to capture that individuals are willing to pay more than $1 to the extent to which they are risk averse. This is measured by the coefficient of relative risk aversion, gamma, and the extent to which they experience a consumption drop upon unemployment. The paper assumes a coefficient of relative risk aversion of 4 and a 9% estimate of consumption drop at job loss from Kolsrud et al. (2018). This leads to a willingness to pay of $1 + 4*$0.09 = $1.36.
With a willingness to pay of $1.36 and a net government cost of $2.35, this leads to an MVPF of 0.58.
