Recent empirical work has found that both aggregate and micro data reject the rational expectations version of the Life Cycle-Permanent Income model of consumption. This paper examines a new possible explanation for the rejections: the treatment of seasonal fluctuations. There are substantial...

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....

This paper analyzes weekly scanner data collected for 108 groups at the county level between 2006 and 2014. The data display multi-dimensional weekly seasonal effects that are not exactly periodic but are cross-sectionally dependent. Existing univariate procedures are imperfect and yield...

In the UK's 2016 referendum on EU membership, young voters were more likely than their elders to vote Remain. Applying new methods to a half century of data, we show that this pattern reflects both ageing and cohort effects. Although voters become more Eurosceptical as they age, recent cohorts...

Every year has large demand and supply shifts associated with the seasons, regardless of the phase of the business cycle. Based on measures dating back to the 1940s, the seasonal shifts reject the hypotheses that demand shifts affect employment outcomes significantly more in recession years than...

This paper examines intra-day patterns of the exchange rate behavior, using the "firm" bid-ask quotes and transactions of USD-JPY and Euro-USD recorded in the electronic broking system of the spot foreign exchange markets. The U-shape of intra-day activities (deals and price changes) and return...

For many products the average price paid by consumers falls during periods of high demand. We use information from a large supermarket chain to decompose the decrease in the average price into a substitution effect, due to an increase in the share of cheaper products, and a price reduction...

We examine the retail prices and wholesale prices of a large supermarket chain in Chicago over seven and one-half years. We show that prices tend to fall during the seasonal demand peak for a product and that changes in retail margins account for most of those price changes; thus we add to the...
