I discuss economic approaches to the demand for harmfully addictive substances and estimate time-series demand functions for the period from 1975 through 2003. My estimates suggest that changes in price can explain a good deal of the observed changes in cigarette smoking, binge alcohol drinking,...

Can variants of the classic Calvo (1983) model of sticky prices account for the statistical behavior of post-war US inflation? We develop and test versions of the model for which the answer to this question is yes. We then investigate whether these models imply plausible degrees of inertia in...

This paper provides an empirical estimate of price' and risk' elasticities of demand for term life insurance for those who purchase some insurance. It finds that the elasticity with respect to changes in premiums is generally higher than the elasticity with respect to changes in risk. It also...

How strong are strategic complementarities in price setting across firms? In this paper, we provide a direct empirical estimate of firm price responses to changes in prices of their competitors. We develop a general framework and an empirical identification strategy to estimate the elasticities...

We propose and estimate a novel specification of the labor demand curve incorporating search frictions and the role of entrepreneurs in new firm creation. Using city-industry variation over four decades, we estimate the employment - wage elasticity to be -1 at the industry-city level and -0.3 at...

We construct shock elasticities that are pricing counterparts to impulse response functions. Recall that impulse response functions measure the importance of next-period shocks for future values of a time series. Shock elasticities measure the contributions to the price and to the expected...

Most US consumers are charged a near-constant retail price for electricity, despite substantial hourly variation in the wholesale market price. The Smart Grid is a set of emerging technologies that, among other effects, will facilitate "real-time pricing" for electricity and increase price...

The response of aggregate labor supply to various changes in the economic environment is central to many economic issues, especially the optimal design of tax policies. This paper surveys recent work that uses structural models and micro data to evaluate the size of this response. Whereas the...
