He suggests substituting consumption out of the model. Combining the log-linear Euler-equations with an approximate log-linear version of the intertemporal budget constraint, he first shows that: 51 c.
However, there may be other discount factors not in X. Unless markets are complete there is an infinite number of random variables E, such that E( EX) = 0 holds, that satisfy the Euler20 See Cochrane (1999a). p. 50. For the original sources see Ross (1978). Harrison/Kreps (1979). Harrison/ Pliska (1981). and HansenlRichard (1987). Chapter 2 26 equation P=E«m+E)X)=E(rnX). In fact, any discount factor can be represented as m = X· + E, with E ( EX) = o. This result can be understood intuitively by considering an economy with several utility maximizing investors.
