Designing Optimal Unemployment Insurance Bertil Holmlund Department of Economics Uppsala University
Outline • Unemployment benefits around the world • Why public UI? • Theoretical background • Optimal UI: Time limits of benefit receipt Monitoring and sanctions Workfare • The financing of UI • UI savings accounts • Conclusions
Unemployment benefits around the world • Unemployment insurance (UI) • Mainly in developed countries • Typically mandatory • Percent of past wage (up to a ceiling) • Time limited • Severance pay • One-time payment • Collective agreements or mandated by gov’ts • Depend on years of service
Unemployment benefits around the world, cont. • Unemployment assistance (UA) • Minimum income guarantee • Often without time limit • Sometimes means tested • Social assistance • Means tested, directed at poor in general • Unemployment insurance savings accounts (UISA) • Forced savings in individual savings accounts • Surplus at retirement age converted into retirement income
Why public UI? • Informational asymmetries • Moral hazard (hidden action) • Adverse selection (hidden characteristics) • Macro shocks – private insurance cannot deal with economic slumps • Public UI an instrument for stabilization policy
Theoretical background Effects of time limits in UI Seminal paper: Mortensen (1977) • Sequential search • Maximization of lifetime utility • Fixed duration of benefit payments • Stochastic duration of employment spells • Eligibility condition: • work must precede benefit receipt
Effects of time limits in UI • The reservation wage declines as the insured worker gets closer to the date at which benefits expire • The exit rate increases with elapsed duration
Exit rate Job finding over the spell of unemployment Benefit period Benefits exhausted Duration Benefits expire
The theory implies that a rise in the benefit level • increases exit rates to employment among workers not eligible for UI (entitlement effect) • causes a newly unemployed worker to increase the reservation wage • but induces an insured worker close to benefit expiration to reduce the reservation wage
Exit rate Effects of a rise in the benefit level Higher benefits Entitlement effect Benefits exhausted Duration
Strong empirical evidence on the impact of the potential duration of benefits: • Job finding increases as the worker gets closer to benefit expiration
Strong empirical evidence on the impact of the potential duration of benefits: • Job finding increases as the worker gets closer to benefit expiration • Not much evidence on entitlement effects
Optimal UI: Time limits • Seminal paper: Shavell and Weiss (1979) • a case for declining time profile • A wage tax as complement: Hopenhayn and Nicolini (1997): • Benefits should decrease over the elapsed duration of unemployment • The wage tax should increase with the length of the previous unemployment spell • Numerical examples: large welfare gains, high replacement rates
Endogenous work effort: Wang and Williamson(1996) • Endogenous inflow into unemployment: the probability of remaining employed is increasing in work effort. • Endogenous outflow from unemployment depends on search effort Implications for optimal UI: • A large drop in consumption in the first period of unemployment (discourages shirking) • A large reemployment bonus (encourages search) • Optimal UI: compensation increases initially and then falls throughout the spell
Collective bargaining in general equilibrium:Cahuc and Lehmann(1997, 2000) • The fall-back position of the union is the welfare of the short-term unemployed • A declining time profile increases the welfare of the short-term unemployed relative to the long-term unemployed • and may therefore increase wage pressure and unemployment
Search equilibrium:Fredriksson and Holmlund (2001) • Endogenous search effort, wage bargaining • Two states of unemployment: • Insured (I) and Non-insured (N) • Stochastic benefit duration • Benefit entitlement through employment
Value functions for Insured, Non-insured and Employed worker
Welfare objective: expected utility of the worker • Is a two-tiered benefit system better than a uniform one? • Yes, in general • Entitlement effect: benefit differentiation encourages search among those who have run out of benefits • The welfare improvement relative to a uniform system is non-trivial
Summary: time profile • A reasonably strong case for a declining time profile • A case for a waiting period? • Discourage shirking • Discourage temporary layoffs • Private savings as a substitute
Monitoring and sanctions • In practice: UI systems condition benefits on performance criteria: • availability for work • actively searching for work • Monitoring through benefit administration (public employment service). • Benefit sanctions if search criteria are not met
Monitoring and sanctions in UI: theoryBoone -van Ours (2006); Boone, Fredriksson, Holmlund , van Ours (2007) • Search and matching model Search effort affects the job finding rate the risk of a benefit sanction
Value function for Insured worker,monitoring and sanctions FOC for optimal search, insured worker:
Monitoring and sanctions in UI: theory • Monitoring and sanctions represent a welfare improvement for reasonable values of monitoring costs Boone, Fredriksson, Holmlund, van Ours (2007)
Evidence on monitoring and sanctions • Social experiments in the United States • Random assignments of unemployed benefit claimants into groups exposed to different search requirements • Washington state, 1986-87 • Maryland, 1994
The Washington study • Treatments: • Varying degrees of work-search requirements • Results: • Workers without search requirements had 3 weeks longer duration of benefit receipt than those with standard requirements
The Maryland study • Treatments: increased search requirements • An increase in the number of required employer contacts from 2 to 4 reduced the duration of benefit receipt by 6 % • Informing claimants that their employer contacts would be monitored reduced the duration of benefit receipt by 7.5 %
Other experimental evidence • Dolton, O’Neill (1996), UK • Risk of losing benefit if not showing up at interview • Fairly strong increase in the exit rate (30 %) • Ashenfelter, Ashmore, Deschenes (1999), USA • Stricter job search requirements • At most very small effect • Van den Berg, van der Klaauw (2001), Netherlands • Counseling and monitoring • No effect on the transition rate from unemployment to employment
Non-experimental evidence on sanctions: How does a sanction affect job finding? • Abbring, van den Berg, van Ours (2005), • Van den Berg, van der Klaauw, van Ours (2004) • Increase in the transition rate to employment by 80-100 % • Lalive, van Ours, Zweimuller (2005) • Swiss evidence on the impact of warnings and actual benefit sanctions • Increase in the outflow from unemployment
Workfare: work required in exchange for benefits Three arguments: • Benefits for the unemployed more politically acceptable • Workfare as a tax on leisure • Workfare as a screening device
Workfare and UI • Informal argument: active labor market policy as workfare • Workfare puts a price on workers’ time • Workers with a high value of leisure self-select out of the benefit system • Formal modeling, example: • Two types of individuals, different preferences for leisure • The government doesn’t know individual preferences, only the distribution Kreiner and Tranaes (2005), Fredriksson and Holmlund (2006)
Can workfare be Pareto improving? Yes! • Absent workfare, searching as well as non-searching individuals may claim benefits • Workfare induces non-searching workers to self-select out of UI (strong preference for leisure) • Makes it possible to raise benefits without making it worse for non-searching individuals
Evidence on workfare • Black, Smith, Berger, Noel (2003), USA • Random assignment into mandatory employment and training services • Participation required in order to receive benefits Results • A reduction in the mean UI duration by about 2 weeks • A marked rise in reemployment before the scheduled program participation
The financing of UI • Current systems • Taxes • (Incomplete) experience rating on firms (USA) • Alternatives • Taxes on workers that depend on their unemployment experiences (cf. unemployment insurance savings accounts) • More stringent experience rating
Pros and cons of experience rating • ER discourages layoffs • But firms have not much influence over workers’ search and job finding • ER is effectively on tax on layoffs and thereby indirectly also a tax on hirings • Many countries already “tax” layoffs through employment protection legislation (EPL) • Optimal mix of ER and EPL?
Unemployment insurance savings accountsFeldstein-Altman (1998), Bovenberg-Sorensen (2004), Stiglitz -Yun (2005) • Mandatory savings of wage income into an unemployment insurance account (UISA) • Job loss: withdraw from the account • If funds are insufficient, borrow from the government • At retirement age: convert UISA into retirement income • The government cancels the debt if the balance is negative
Pros and cons of UISA • UISA reduces moral hazard problems • The worker finances her own benefits • UISA allows borrowing against future income • Some workers will retire with negative balances • How common? • Rules for withdrawal • Worker heterogeneity and distributional issues
Conclusions • The case for penalizing less active search is solid • Indirect penalty: a declining time profile • More direct penalty via monitoring of search • Workfare can be a useful screening device • Caveats • Low benefits during the first week(s) would discourage unemployment entry • Precautionary savings • UISA may be a useful complement to UI
