Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But the theoretical foundation of most studies is a cost minimisation and/ or profit maximisation problem assuming perfect input markets. At the very least, traditional input price proxies therefore contain substantial measurement error. In th...

We analyze the role of search frictions in the market for commercial health insurance. Frictions increase the cost of insurance by enabling insurers to set price above marginal cost, and by creating incentives for inefficiently high levels of marketing. Frictions also lead to price dispersion for identical products and, as a consequence, to increases in the rate of insurance turnover. Our empir...

A number of recent papers have explored monetary policy options, including inflation targeting and inflation forecast targeting (notably Svensson (1999a, 1999b, 2000)) and price level targeting (Wolman 2000, Batini and Yates 1999, Blinder 1999). Most papers explore “optimal” monetary policy in the context of a single model. However, a number of conclusions made in the literature depend strongly...

Monetary policy is a blunt instrument with which to smooth aggregate volatility. I demonstrate that there is actually very little correlation between how much real state income responds to monetary policy and to shocks that prompt aggregate smoothing by the Federal Reserve. This mismatch turns out to be strong enough to imply that while monetary policy might have reduced the variance of aggrega...

In this paper we explore the influence of the possibility to short stocks and/or borrow money in laboratory markets. A key innovation of our study is that subjects can simultaneously trade two risky assets on two double-auction markets, allowing us to differentiate between assets with relatively high versus low capitalization. Divergence of opinions is created by providing each trader with nois...

We analyze a duopoly model where …rms sell conspicuous goods to horizontallyand vertically-di¤erentiated consumers. These consumers care about both the intrinsic quality of the goods they purchase as well as the “social status”conveyed by these goods (namely, the social inference of their hidden wealth based on their purchase). Firms o¤er non-linear price and quality schedules that, in e¤ect, s...

This paper explores the used motor oil markets in California under the regulatory scheme along with potential distortions introduced from elements of SB 546. California Senate Bill (SB) 545 modified the requirements of the deposit-refund system (DRS) for used oil outlined in the California Oil Recycling Enhancement Act (COREA) by introducing a differential fee and incentive system. The motivati...

Six hens pecked a key (Experiment 1) or pushed a door (Experiment 2) to obtain food reinforcement. In both experiments and as an analogue of price changes, the response requirements were varied in two ways: by increasing the number of responses required and by increasing the required force of each response. The two price manipulations (response number and response force) had different effects o...
