There is a general presumption that social preferences can be ignored if markets are competitive. Market experiments (Smith 1962) and recent theoretical results (Dufwenberg et al. 2008) suggest that competition forces people to behave as if they were purely self-interested. We qualify this view....

The standard model on optimal income taxation in the presence of tax evasion is extended to allow for mobility between the legal and hidden sectors. The conclusions from the traditional analysis of tax evasion strongly contrast with those that result when extensive margin responses are taken...
