Search effort Factor Relation to search effort Finding Sorting Prior information Learning High effort searchers find jobs more quickly, leaving the low effort ones Searchers find out about available jobs fairly easily at the outset of search and then spend time waiting for prospects to materialize Appears to be the opposite, but measurement problems may be the reason Strongly supported Appears to be strongly supported, but Searchers reduce effort after early results measurement problems may be the are unfavorable reason Wealth Unemployment insurance As wealth is depleted, search becomes more intense Once benefits are exhausted, search becomes more intensive.

Reservation wage Factor Relation to reservation wage Finding Sorting Prior information Learning Wealth Unemployment insurance Low reservation wage searchers depart unemployment soon, leaving high reservation wage searchers. Wages are known at the outset, so there is no decline during unemployment Searchers cut reservation wages after learning that higher-wage jobs are not available. As wealth is depleted, reservation wages decline Benefits: Once exhausted, reservation wage declines. Rejected Strongly supported Rejected Rejected Not discussed but implicitly supported 4
