Alcohol Prohibition and Pricing at the Pump*

Firms often sell a transparent base product and a valuable add-on. If only some consumers are aware of the latter, the add-on's effect on the base product's price will be ambiguous. Cross-subsidization between products to bait uninformed consumers might lower, intrinsic utility from the add-on for informed consumers might raise the price. We study this trade-off in the gasoline market by exploiting an alcohol sales prohibition at stations as an exogenous shifter of add-on availability. Gasoline margins drop by 5% during the prohibition. The effect is mediated by shop variety and competition. Using traffic data, we unveil sizeable consumer-side reactions.     

Recycling of carbon/energy taxes and the labor market

This paper provides a quantitative assessmet of a cost shift from labor to energy by means of a carbon/energy tax. The analysis utilizes a general equilibrium model for the European Community, placing the emphasis on the modeling of labor supply. The paper highlights the importance of the feedback from an induced increase in labor demand to wage formation. It shows that the goals of CO₂ reduction and improved employment are complementary, provided the reduction in labor costs financed by the carbon/energy tax is not offset by increased wage claims. Under this condition, reduced CO₂ is consistent with an increase in GDP.
