The point of this paper is that inventory adjustment attenuates downward pressure on price when realized demand is low because firms accumulate inventory hold-overs, speculating that demand will be stronger in the succeeding period. When realized demand is high the firm draws down its inventories until a "stock-out" occurs and price rises to clear the market.

A consumer faces list prices for commodities, but can buy one at a discount. Discounts vary randomly between sellers. The number of quotations sought depends on list prices, search costs and wealth. This function is homogeneous of degree zero, and, provided some sufficient conditions are satisfied, is; increasing in wealth; decreasing in search cost; independent of the list price of the discounted commodity if indirect utility is multiplicatively separable; increasing in the list price if the commodity is a necessity; increasing in the list price of substitutes. Slutsky's equation is generalized to include search.

The literature on inequality measurement has been largely concerned with single-dimensioned indicators. This paper explores some of the issues which arise when there are several dimensions to inequality, and these are not readily reduced to a single index, concentrating particularly on the two-dimensioned case. We make use of results on multi-variate stochastic dominance in portfolio theory, extending these and applying them to the measurement of inequality. The use of the dominance conditions is illustrated by an application to the international distribution of income and life expectancy.

This paper examines the relative importance of timing and persistence elements in explaining cyclical fluctuations in labour supply. Data from the natural experiment provided by World War II and cross-sectional data on American local labour markets, as well as aggregate time-series data are used in the empirical work. We find little evidence that timing effects play an important role in labour market dynamics. The evidence suggests that views emphasizing persistence are more accurate, and that previous employment tends to raise the probability of subsequent employment.
