The relationship between employer size and within firm job mobility is investigated. Larger employers are posited to provide their workers with greater options for career advancement within the firm in an attempt to both protect (and encourage) the relatively higher investments in their workers and to evaluate employee performance. Using microdata on actual levels of internal mobility, direct support is found for the propositions of greater internal mobility in larger establishments.

This study tests the hypothesis that price expectations differ across individuals because they acquire different information about inflation. If price information is a normal good, then the amount of price information acquired will vary across individuals according to income, education, and other demand-specific variables, causing price expectations to be heteroscedastic with respect to these variables. Utilizing monthly household survey data, the authors test the heteroscedasticity hypothesis and find support for the differential information model. In addition, they develop a novel method of incorporating the "don't know" response to questions about inflation into the estimation of price expectations.
