"This paper presents new evidence on why unemployment insurance (UI) benefits affect search behavior and develops a simple method of calculating the welfare gains from UI using this evidence. I show that 60 percent of the increase in unemployment durations caused by UI benefits is due to a...

"Since Feldstein (1999), the most widely used method of calculating the excess burden of income taxation is to estimate the effect of tax rates on reported taxable income. This paper reevaluates the taxable income elasticity as a measure of excess burden when individuals can evade or avoid...

"I derive bounds on price elasticities in a dynamic model that is mis-specified due to optimization frictions such as adjustment costs or inattention. The bounds are a function of the observed effect of a price change on demand, the size of the price change, and the degree of frictions. I...

"Studies of the consumption-smoothing benefits of unemployment insurance (UI) have found that the optimal benefit level is very small, perhaps even 0, for conventional levels of risk aversion. In this paper, I derive a formula for the optimal benefit rate in terms of income and price...
