Constant-sum sampling: an apology for statistics' “original sin”

Powers, Michael R. - In: Journal of Risk Finance 10 (2009) August, pp. 317-320

Defining Bad News: Changes in Return Distributions That Decrease Risky Asset Demand

Hollifield, Burton; Kraus, Alan - In: Management Science 55 (2009) 7, pp. 1227-1236

We provide a random variable characterization of the necessary and sufficient conditions for a shift of the distribution of rate of return on the risky asset in the two-asset portfolio problem to reduce demand for all strictly risk-averse expected-utility-maximizing investors. We also provide...

Day-To-Day Monetary Policy and the Volatility of the Federal Funds Interest Rate

Prati, Alessandro; Bertola, Giuseppe; Bartolini, Leonardo - International Monetary Fund (IMF) - 2000

We propose a model of the interbank money market with an explicit role for central bank intervention and periodic reserve requirements, and study the interaction of profit-maximizing banks with a central bank targeting interest rates at high frequency. The model yields predictions on biweekly...
