One Markup to Rule Them All: Taxation by Liquor Pricing Regulation

Commodity taxation often involves uniform tax rates. We use alcohol laws that tax differentiated spirits with a comprehensive uniform markup to evaluate redistribution generated by such simple tax policy. We document preference heterogeneity among consumers, variation in product demand elasticities, and market power among producers with heterogeneous product portfolios. Relative to more flexible product-level markups recognizing demand heterogeneity and strategic price responses of firms, we find that the uniform markup underprices less elastic spirits, implicitly subsidizing low-income and less educated residents. The uniform markup grants additional market power to small specialized firms whose product positioning benefits from the policy.(JEL D12, H21, H23, H25, L43, L66)

Optimal Taxation with Behavioral Agents

This paper develops a theory of optimal taxation with behavioral agents. We use a general framework that encompasses a wide range of biases such as misperceptions and internalities. We revisit the three pillars of optimal taxation: Ramsey (linear commodity taxation to raise revenues and redistribute), Pigou (linear commodity taxation to correct externalities), and Mirrlees (nonlinear income taxation). We show how the canonical optimal tax formulas are modified and lead to novel economic insights. We also show how to incorporate nudges in the optimal taxation framework, and jointly characterize optimal taxes and nudges. (JEL D62, D91, H21)
