Mount mechanisms for the Saturn 5/Apollo mobile launcher at John F. Kennedy Space Center

A support system was designed to resist hurricane wind loads at the launch pad and to allow the supported structural frame to expand and contract freely under wide ranges of temperature. This system consists of six mount mechanisms devised to meet the previously stated requirements plus a load-carrying capacity for each of 3.2-million kilograms (7-million pounds) downward and 1.6-million kilograms (3.5-million pounds) upward. A similar but lighter system of six mount mechanisms was designed for use in the sheltered environment of the vehicle assembly building. Each requirement and design result is discussed, and each mount mechanism is defined by location and type with references to visual presentations

The relative price effects of monetary shocks

We document the response of the individual components of the Producer Price Index (PPI) to commonly used measures of monetary shocks, and show that these responses are at variance with many widely-used “macro” models of monetary non-neutrality. Monetary shocks are shown to have large relative price effects, resulting in an increase in the dispersion of the cross-section distribution of prices. Furthermore, in response to a contractionary (expansionary) monetary shock, a substantial number of prices tend to rise (fall). Most of the existing models of monetary nonneutrality are not capable of replicating these types of relative price responses.

Recessions and recoveries

The U.S. recession that began in July 1990 may have ended in April or May 1991. The pace of the subsequent recovery has been so sluggish as to be indistinguishable, in the eyes of many, from continued recession. One explanation for the sluggish pace of the recovery is that the recession itself was not particularly severe, at least when compared with others. ; In this article, Mark Wynne and Nathan Balke use monthly data on industrial production to examine the hypothesis that the severity of a recession determines the pace of the subsequent recovery. They show that, historically, the relationship between growth in the first twelve months of a recovery and the decline in industrial activity from peak to trough is statistically significant. However, there is no relationship between the length of a recession and the strength of the recovery. Consistent with their finding of a bounce-back effect for industrial production, the recovery from the 1990-91 recession is the weakest in the period covered by the Federal Reserve Board's industrial production index, just as the decline in industrial production over the course of that recession is the mildest on record.Production (Economic theory) ; Recessions

Crude oil and gasoline prices: an asymmetric relationship?

Gasoline is the petroleum product whose price is most visible and, therefore, always under public scrutiny. Many claim there is an asymmetric relationship between gasoline and oil prices - specifically, gasoline price changes follow oil price changes more quickly when oil prices are rising than when they are falling. To explore this issue, Nathan Balke, Stephen Brown and Mine Yucel use several different model specifications to analyze the relationship between oil prices and the spot, wholesale, and retail prices of gasoline. They find asymmetry is sensitive to model specification but is pervasive with the most general model.Petroleum industry and trade ; Prices
