Unshrouding: Evidence from Bank Overdrafts in Turkey

Lower prices produce higher demand… or do they? A bank's direct marketing to holders of “free” checking accounts shows that a large discount on 60% APR overdrafts reduces overdraft usage, especially when bundled with a discount on debit card or autodebit transactions. In contrast, messages mentioning overdraft availability without mentioning price increase usage. Neither change persists long after the messages stop. These results do not square easily with classical models of consumer choice and firm competition. Instead, they support behavioral models where consumers underestimate and are inattentive to overdraft costs, and firms respond by shrouding overdraft prices in equilibrium.     

CONSERVED ENERGY SUPPLY CURVES FOR U.S. BUILDINGS

Comparison of nine conservation supply curves for electricity shows that fully implementing a series of energy efficiency measures will result in annual saving of 734 billion kWh (BkWh). This is 45 percent of 1989 U.S. building sector electricity use of 1627 BkWh and represents a $29 billion saving. When translated to units of conserved carbon dioxide (CC CO₂), this annual saving is 514 megatonnes, which is 10 percent of the total 1989 U.S. carbon dioxide (CO₂) emissions from all sources. Implementing additional fuel efficiency measures would result in further potential saving of 5·2 quads of fuel (natural gas and oil) per year, or another 300 megatonnes of CO₂, at a net savings of $20 billion. Fuel switching (replacing electric resistance heat with on-site natural gas combustion) would produce annual saving of another 74 megatonnes of CO₂ at a net saving of $6·8 billion. Thus, total CO₂ saving from these combined efficiency measures are 890 megatonnes at a net saving of $56 billion per year.     

Optimal Fiscal and Monetary Policy in Customer Markets

We present a model in which some goods trade in “customer markets” and advertising facilitates long‐lived relationships. We estimate the model on U.S. data and find a large congestion externality in the pricing of customer market goods. This motivates the analysis of optimal policy. Under a complete set of taxes, fiscal policy eliminates the externalities with large adjustments in tax rates on customer markets goods, while labor tax volatility remains low. Constraining the instruments to the interest rate and labor tax, the optimal labor tax displays large and procyclical fluctuations, but monetary policy is little changed compared to a model with no customer markets.     

The Differing Nature of Consumerism in the Ghetto

Does a consumer movement that is white and middle class benefit those who are not white and not middle class? This paper argues that the movement is not likely, and perhaps ought not, to have major impact on ghetto consumer problems since those problems too often are qualitatively, not just quantitatively, different from those of the white middle class. Middle class misunderstanding of disadvantaged consumers' problems offers the strong suggestion that middle class involvement in problem solutions may make the situation worse not better.
