In a model where a variable Y[sub t] is proportional to the present value, with constant discount rate, of expected future values of a variable y[sub t] the "spread" S[sub t]= Y[sub t] - [theta sub t] will be stationary for some [theta] whether or not y[sub t]must be differenced to induce...

A broad exploratory data analysis is conducted to assess the promise of a kind of model in which long-term asset prices change through time primarily due to consumption related changes in the rate of discount. Aggregate consumption data are used to infer ex-post marginal rates of substitution....
