We examine the importance of intertemporal substitution in U.S. import consumption using a model of permanent income that allows for random preference shocks and additive separability. The latter feature allows us to take two estimation approaches. In the first approach, we show that there is a...

Various empirical specifications of the permanent income model are investigated using Canadian aggregate data. Tests for structural changes with known and unknown change point are applied to the models estimated by the generalized method of moments. The proportion of current income individuals...

This paper tests the prediction of the Permanent Income Hypothesis (PIH) that news about future income induce a revision in consumption equal to the revision in permanent income. We use time-series data from 48 contiguous US states to perform the test. The empirical results provide some support...

This paper investigates whether time-series data from 11 West-German states (Länder) provide evidence in accord with the implication of the permanent-income hypothesis (PIH) for the stochastic relationship between consumption and income innovations. The empirical results do not support this...

This paper considers a general permanent-income model in which a fraction of consumers in the economy is liquidity constrained. Consumption growth rate for these individuals is related to the growth rate of their income and the level of real interest rates. The interest-rate coefficient is...
