We examine daily prices of eight goods at seventeen retail stores collected in Ann Arbor, Michigan, over a four-month period from November 1 to February 28. We focus on weekly and seasonal price patterns, and on the frequency of price markdowns or “sales.” There were frequent markdowns in the intensive shopping period prior to Christmas, and a tendency for such sales to occur on weekends. We interpret these findings as evidence that a significant number of markdowns are timed to occur when shopping intensity is exogenously high. We complement the imperfect information-based motives for sales in the literature by contributing an additional element based on the role of bulk shopping and increasing returns in the shopping technology.

Major long-run swings in the U. S. stock market over the past century are broadly consistent with a model driven by changes in current and expected future dividends in which investors must estimate the time-varying long-run dividend growth rate. Such an estimated long-run growth rate resembles a long distributed lag on past dividend growth, and is highly correlated with the level of dividends. Prices therefore respond more than proportionately to long-run movements in dividends. The time-varying component of dividend growth need not be detectable in the dividend data for it to have large effects on stock prices.

We examine interest and inflation rates from 1879 to 1913. Deflation prior to 1896 was followed by inflation. Average U. S. inflation was 3.1 percentage points higher in the years after 1896, yet nominal interest rates were no higher after 1896. This nonadjustment of nominal rates would be consistent with rational expectations if inflation was not forecastable, and indeed univariate tests show little sign of serial correlation. But gold production does forecast inflation. The relationship between mining and inflation was such that expected inflation should have risen 300 basis points between 1890 and 1910. We consider explanations of this failure to foresee the shift in inflation after 1896 and conclude that it is not persuasive evidence that investors ignored relevant information, but does suggest great uncertainty about the appropriate model for analyzing the economy.

This paper reports measures of preference parameters relating to risk tolerance, time preference, and intertemporal substitution. These measures are based on survey responses to hypothetical situations constructed using an economic theorist's concept of the underlying parameters. The individual measures of preference parameters display heterogeneity. Estimated risk tolerance and the elasticity of intertemporal substitution are essentially uncorrelated across individuals. Measured risk tolerance is positively related to risky behaviors, including smoking, drinking, failing to have insurance, and holding stocks rather than Treasury bills. These relationships are both statistically and quantitatively significant, although measured risk tolerance explains only a small fraction of the variation of the studied behaviors.
