“…See, for example,Gruber (1997) on consumption smoothing, andMeyer (1990),Lalive et al (2006) andChetty (2008) on the moral hazard costs of UI.2 These papers find that traditional UI should be followed by monitored or assisted search and then social assistance. Other related papers include a simple study of monitoring with linear precision in van der Linden(2003), and more recent principal-agent papers such asSetty (2019), which considers monitoring of binary search,Pavoni et al (2016), who study 'soft' programs including JSA, andJung and Kuester (2015), who consider the optimal combination of UI, vacancy subsidies, and layoff taxes in recessions.3 See also, for example,Hansen and İmrohoroğlu (1992) for optimal UI andMichelacci and Ruffo (2015) for life-cycle UI.4 van der Linden (2003) includes a payroll tax paid by firms, whileWunsch (2013) andSetty (2019) calibrate their models to tax rates of 36% and 29% respectively. There is no inherent distinction between welfare-maximization and principal-agent approaches on this dimension: even though principal-agent models assume that the planner 'owns' the agent's consumption, such models will not incorporate fiscal externalities from income taxes unless the model features a revenue requirement for spending by the planner.…”
