It is often argued that price indexes do not fully capture the quality improvements of new goods in the market. Because of this shortcoming, price indexes are perceived to overestimate the actual price increases that occur. In this paper, I argue that the quality bias in price indexes is just as...

How does information management and control affect bank stability? Following a national bank holiday in 1933, New York state bank regulators suspended the publication of balance sheets of state-charter banks for two years, whereas the national-charter bank regulator did not. We use this...

Central banks have become increasingly communicative. An important reason is that democratic societies expect more transparency from public institutions. Central bankers, based on empirical research, also believe that sharing information has economic benefits. Communication is seen as a way to...

We characterize optimal state-dependent pricing rules under various forms of infrequent information. In all models, infrequent price changes arise from the existence of a lump-sum “menu cost.” We entertain various alternatives for the source and nature of infrequent information. In two...

How rigid are producer prices? A longstanding conventional wisdom among economists holds that producer prices are more rigid than, and so play less of an allocative role than do, consumer prices. In the 1987-2008 microdata collected by the U.S. Bureau of Labor Statistics for the producer price...

While many analyses of monetary policy consider only a target for a short-term nominal interest rate, other dimensions of policy have recently been of greater importance: changes in the supply of bank reserves, changes in the assets acquired by central banks, and changes in the interest rate...

The financial crisis of 2007-09 has sparked keen interest in models of financial frictions and their impact on macro activity. Most models share the feature that borrowers suffer a contraction in the quantity of credit. However, the evidence suggests that although bank lending contracted during...

We construct a model in which bank capital regulation and financial innovation interact. Innovation takes the form of pooling and tranching of assets and the creation of separate structures with different seniority, different risk, and different capital charges, a process that captures some...

Should policy makers be prevented from bailing out investors in the event of a crisis? I study this question in a model of financial intermediation with limited commitment. When a crisis occurs, the efficient policy response is to use public resources to augment the private consumption of those...

We model transitional dynamics that emerge after the adoption of a new monetary policy rule. We assume that private agents learn about the new policy via Bayesian updating, and we study how learning affects the nature of the transition and the choice of a new rule. Temporarily explosive dynamics...
