A modern household's consumption bundle is more finished than that of a typical worker in the past: the average consumption good passes through more stages of production before purchase. This has affected the cyclical behavior of wages relative to the price of the consumption bundle because wages are more procyclical relative to prices of more-finished goods. Nowadays real consumption wages are procyclical. They were less procyclical before the Second World War, and they may have been acyclical or even countercyclical before the First World War.

Most current literature assumes that a central bank loses the ability to influence interest rates through variations in reserve supply as soon as overnight rates have been driven to zero. I argue that reserve supply can be directly related to longer-term rates when overnight rates are zero because banks' reserve demand is then defined by the role of cash as an asset free of interest-rate risk. I present evidence that reserve supply affected longer-term interest rates in the U.S. from 1934 through 1939, while overnight rates were at the zero floor, even when the changes in reserve supply reflected factors unlikely to have affected expectations of future overnight rates.
