Brian Galle (Florida State) has posted Do Hidden Taxes Increase Welfare? on SSRN.  Here is the abstract:

This preliminary idea draft offers a critical review of the economic literatue on the efficiency of low-salience taxes. In particular, I explore the possibility that hidden taxes may in fact be more efficient than others. Since the entire field comprises only a handful of papers, the review is devoted mostly to identifying gaps in our present understanding. For example, the literature so far omits any consideration of the impact of hidden taxes on fiscal federalism, and gives only glancing attention to possible distributive consequences, both topics I attempt to highlight here. Additionally, I attempt to integrate with the tax literature some recent developments in our understanding of bounded rationality in consumers more generally.
