Abstract :

"We propose a model of job search with reference-dependent preferences, where the reference point is given by recent income. Newly unemployed individuals search hard given that they are at a loss, but over time they get used to lower income, and thus reduce their search eort.In anticipation of a benet cut their search eort rises again, to then decline once they get used to the new benet level. The model ts the typical pattern of the exit from unemployment, even with no unobserved heterogeneity. The model also makes distinguishing predictions regarding the response to benet changes, which we evaluate using a unique reform. In 2005, Hungary switched from a single-step UI system to a two-step system, with unchanged overall generosity. The system generated increased hazard rates in anticipation of, and especially following, benet cuts in ways the standard model has a hard time explaining. We structurally estimate a model with optimal consumption-savings and endogenous search eort, as well as unobserved heterogeneity. The reference-dependent model ts the hazard rates substantially better than the standard model, holding constant the number of parameters. We estimate a signicant weight on gain-loss utility and a speed of adjustment of the reference point in the order of six months. The estimates also point to substantial impatience, likely in the form of present-bias. Estimates of a variety of alternative models, including habit formation, do not come close to the t of the reference-dependent model."
