Stable distributions are suggested as being the underlying distributions for many economic variables. Capital market variables, in particular, are said to follow a member of the symmetric stable class.

Abstract Inflation targeting is gaining popularity as a framework for conducting monetary policy. At the same time many countries employ some sort of foreign exchange intervention policy assuming that these two policies can coexist. This paper attempts to show that both policies are not sustainable. Israel is a classic test case. We test our hypothesis using information from the financial markets. The results support the hypothesis that both policies cannot be sustained in the long run. The conclusion is that a credible monetary policy aimed at inflation targets should be conducted in a free floating exchange rate regime.
