The welfare gains from adopting a zero nominal interest policy depend on the implementation details. Here I focus on a government loan program that crowds out lending and borrowing and other money substitutes. Since money can be costlessly created the resources spent on creating money...

We use large unpublished data set about the prices by store of 381 products collected by the Israeli bureau of statistics during 1991-92 in the process of computing the CPI. On average 24% of the stores changed their price where the average is over products and months. Using the standard...

The welfare gains from adopting a zero nominal interest policy depend on the implementation details. Here I argue that implementing the Friedman rule by a government loan program may be better than implementing it by collecting taxes, even when lump sum taxes are possible. The government loan...

The standard power utility function is widely used to explain asset prices. It assumes that the coefficient of relative risk aversion is the inverse of the elasticity of substitution. Here I use the Kihlstrom and Mirman (1974) expected utility approach to relax this assumption. I use time...

This paper uses a recursive time-non-separable expected utility function to separate between the intertemporal elasticity of substitution (IES) and a measure of relative risk aversion to bets in terms of money (RAM). Risk premium does not require risk aversion. Changes in IES have large effects...

I use price dispersion to model liquidity. Buyers may be rationed at the low price. An asset is more liquid if it is used relatively more in low price transactions and the probability that it will buy at the low price is relatively high. In the equilibrium of interest government bonds are more...

I examine the implementation of the Friedman rule under the assumption that age dependent lump sum transfers are possible and private intermediation is costly. This is done both in an infinitely lived agents model and in an overlapping generations model. I argue that in addition to a zero...

I examine the argument that a low interest rate policy can lead to "overvalued" private assets or privately created bubbles (private bubbles). Using the standard approach to bubbles, I find that a policy of a low real interest rate may support private bubbles but a policy of a low nominal...

I use a flexible price version of the Prescott (1975) hotels model to explain variations in price dispersion across goods sold by supermarkets in Chicago. The main finding is that price dispersion measures are positively correlated with proxies for demand uncertainty. I also find that price...

This paper studies the possibility of using financial regulation that prohibits the use of money substitutes as a tool for mitigating the adverse effects of deviations from the Friedman rule. When inflation is not too high regulation aimed at eliminating money substitutes improves welfare by...
