Seasonal adjustment procedures attempt to estimate the sample realizations of an unobservable economic time series in the presence of both seasonal factors and irregular factors. In this paper we consider a factor which has not been considered explicitly in previous treatments of seasonal...

The following paper discusses the analysis of some types of economic time series using an altered time scale, or operational time. It is argued that for some series, observations that are ordinarily thought of as equidistant in time are actually irregularly spaced in a more natural time scale....

Traffic fatalities are the leading cause of mortality in the United States despite being preventable. While several policies have been introduced to improve traffic safety and their effects have been well documented, the role of transitory health shocks or situational factors at explaining...

The real price of recreation goods and services has fallen dramatically over the last century. At the same time, hours per worker have also been on a steady decline. As recreation goods make leisure time more enjoyable, we investigate if the fall in their price has contributed to the decline in...

Economists have long been puzzled by event-ticket underpricing: underpricing both reduces revenue and encourages socially wasteful rent-seeking by ticket brokers. This paper studies the introduction of auctions into this market by Ticketmaster. We first show theoretically that Ticketmaster's...

This paper argues that analysis of seasonal fluctuations can shed light on the nature of business cycle fluctuations. The fundamental reason is that in many instances identifying restrictions about seasonal fluctuations are more believable than analogous restrictions about non-seasonal...
