Dispersion of money balances among individuals is the basis for a range of policies but it has been abstracted from in monetary theory for tractability reasons. In this paper, we fill in this gap by constructing a tractable search model of money with a non-degenerate distribution of money...

When a society wants to control aggregate emission under a certain target, is it more desirable to impose a tax or a nontradable regulatory standard on emission? We answer this question by focusing on the role of productivity heterogeneity across a continuum of plants. The plants are...
