The permanent income hypothesis in underdeveloped economies:: Additional evidence

Laumas and Laumas find no support for the permanent income hypothesis in recent work on a consumption function for India. However, permanent income has been used not only in consumption but also in demand for money functions. Estimates of demand for money in 10 Asian LDCs indicate that substitution of permanent for current income is warranted. In particular, the estimate for India is improved substantially by the use of permanent instead of current income. Furthermore, the weights obtained from a polynomial lag distribution are almost identical to the Laumas' exponential weights with which they construct permanent income.

A test of the permanent income hypothesis on Czech voucher privatization

In 1992 the Czech Republic privatized state assets, which resulted in some citizens receiving an unexpected windfall. Whether the windfall was consumed or saved provides a clear test of the permanent income hypothesis in a transitional economy. Analysis of data from a survey conducted specifically to test this hypothesis indicates that only a small number of transferred assets were consumed, a finding which is consistent with the permanent income hypothesis. JEL classification: D31, E21, H24.     

A Permanent Income Model of Public Consumption

This paper tests the permanent income hypothesis (PIH) for public consumption. Unlike private agents, a government is a representative national, infinitely-lived agent that usually faces no liquidity constraints. Thus, the expectation is that the PIH restrictions should not be rejected for public consumption. However, using U.S. data, the paper is unable to find evidence supporting the permanent income model of public consumption. Public consumption is found to be sensitive to lagged public income and too smooth relative to permanent public income. The results therefore cast doubt on the characterization of the public sector as a social welfare optimizing agent.

Why Do the Rich Save More? A Theory and Australian Evidence*

We provide a theory to explain the existence of inequality in an economy where agents have identical preferences and have access to the same production technology. Agents consume a ‘health’ good which determines their subjective discount factor. Depending on initial distribution of capital the economy gets separated into different permanent‐income groups. This leads to a testable hypothesis: ‘The rich save a larger proportion of their permanent‐income’. We test this implication for savings behaviour in Australia. We find that even after controlling for lifecycle and health characteristics, higher permanent income is positively related with higher savings rates and better saving habits.     

Permanent income hypothesis: An optimal control theory approach to a classical macro thesis

This paper investigates the extent by which the permanent income hypothesis (the normal income and the proportionality hypotheses) can be obtained by the optimal control approach with an explicit recognition of individual's rational behavior over time.     

The permanent income hypothesis and the real interest rate: Some evidence from panel data

A test of the permanent income hypothesis in panel data is formulated taking into account both the time-series and cross-section variation in the rate of return. The over-identifying restrictions of the theory rejected.     

Risk Sharing and Information in Village Economies

Arrangements for achieving efficient risk-sharing vary depending on the information available to agents in the economy. The usual Euler equation restricts efficient allocations in an economy which obeys the permanent income hypothesis, while efficient allocations in an economy with private information and long-term contracts satisfy a symmetric restriction, but not the Euler equation. Full insurance arrangements are unique in that they satisfy both restrictions.
We look at an environment in which it seems likely that long-term contracts play a role in mitigating the effects of private information: three village economies in South India. The evidence that consumption allocations satisfy the private information restriction is quite strong for households in two of the three villages; the evidence for the third village suggests that while consumption for some households satisfies the private information restrictions, other households' consumption obey the permanent income hypothesis.     

Variations in farm consumption and their relationship to income: an empirical investigation of Illinois farm households

Empirical tests of household consumption have yielded mixed results regarding the validity of the life cycle/permanent income (LCPI) hypothesis. A significant problem with such studies is the difficulty in finding sufficient micro-level data on household expenditures. By using the recent rich quantity of such data in the Farm Business Farm Management (FBFM) data for Illinois farms from 1995 to 2009, the study reported here for farm households should provide more consistent results regarding the LCPI hypothesis. Applying an empirical model based on the LCPI hypothesis, this article identifies the determinants of farm consumption and the relationship to income. This study provides evidence that current income changes are not significant in explaining the consumption changes of farm households, thus supporting the LCPI hypothesis for farm households.     

The permanent income hypothesis in an underdeveloped economy

After a concise but critical survey of several tests of the permanent income hypothesis (PIH), the authors advance their own test for India using annual data from 1919–1960. It employs Friedman's technique for calculating the permanent value of a variable. Two different specifications of the model are tested, using different values of the consumer's ‘horizon.’ In almost all cases it is found that the marginal propensity to consume out of transitory income is very similar to the marginal propensity to consume out of permanent income. The authors conclude that even a looser variant of the PIH is not valid for India. However, no valid generalization with respect to the appropriate planning horizon can be made, for the PIH was almost equally invalid with a horizon of one, two and two-and-a-half years. The authors briefly discuss the policy implications of their results for the savings efforts in underdeveloped countries.     

Stein-rule least squares estimation: A heuristic for fallible data

For fallible data, ‘errors-in-variables’, a Steinian estimation of the independent variable yields a consistent and potentially unbiased estimator of the regression coefficient. This estimator suggests a heuristic for economic research and is illustrated by the permanent income hypothesis.     

Has Financial Deregulation Revived the Permanent Income/Life Cycle Hypothesis?

The permanent income/life cycle hypothesis is tested using Australian data for periods covering the regulated and deregulated financial systems. The hypothesis is rejected for the entire sample period. Further investigation reveals that the rejection is confined to the period in which the financial system was regulated. The evidence points to liquidity constraints as being the cause of this rejection although the existence of myopic consumers may also be a possibility.     

Reexamining the permanent income hypothesis with uncertainty in permanent and transitory innovation states

In this paper, we reexamine the permanent income–consumption relationship analytically and empirically, based on the innovation regime-switching (IRS) model developed in [Kuan, C.M., Huang, Y.L., Tsay, R.S., 2005. An unobserved component model with switching permanent and transitory innovations. Journal of Business and Economic Statistics, 23, 443–454]. A novel feature of the IRS model is that it explicitly allows for uncertainty in innovation states. When the labor income follows an IRS process, it is shown that the agent’s perception on the likelihoods of income innovations being permanent and transitory plays a crucial role in determining the optimal forecasts on the change of consumption. The effect of a current labor income innovation on consumption is a weighted average of two distinct effects resulting from permanent and transitory innovations with the weights equal to the perceived likelihoods of the respective states. Also, past innovations may affect consumption when there are revisions in the perceived likelihoods of previous states. Our empirical study on US data shows that consumption indeed reacts significantly to the perceived likelihoods of innovation states. However, even after controlling for the effect of state uncertainty, we find consumption vastly underreacts to permanent innovations in labor income but reacts about the right magnitude to transitory ones when compared with the prediction of the permanent income hypothesis. This evidence is similar to [Elwood, S.K., 1998. Testing for excess sensitivity in consumption: A state-space unobserved components approach. Journal of Money, Credit, and Banking, 30, 64–82] but in sharp contrast with that found in [Hall, R.E., Mishkin, F.S., 1982. The sensitivity of consumption to transitory income: Estimates from panel data on households. Econometrica, 50, 461–480].     

The effect of household characteristics on saving behaviour and the theory of savings in Japan

The purpose of this paper is to estimate the household saving functions based on cross-section data which contain fruitful informations of individual observations. The paper also attempts to test various theories of saving behaviours empirically such as life-cycle saving hypothesis, or permanent income hypothesis, or several other theories. Since the data contain several useful variables which have not been used previously, particular attention is paid to the influence of those household characteristics on saving behaviour.     

A reexamination of the consumption function using frequency domain regressions

This paper reexamines the permanent income hypothesis (PIH) in the frequency domain. In contrast to some time domain tests, our frequency domain approach provides an explicit and natural test ofboth the permanentand transitory implications of the PIH for jointly nonstationary consumption and income data. Using a simple theoretical model, we demonstrate that the PIH implies the marginal propensity to consume (MPC) out of zero frequency income is unity. The PIHalso implies that the theoretical MPC out of transitory (or high frequency) income is smaller than the long-run MPC. These theoretical restrictions are natural implications of Friedman's hypothesis that agents consume out of permanent or low frequency income and (dis)save out of transitory or high frequency income. We test this full set of restrictions directly using spectral regression techniques. Under our set of assumptions, the derived disposable income process is shown to have a unit root and to be cointegrated with consumption. We therefore employ a systems spectral regression procedure that accommodates stochastic trends in the consumption and income series as well as the joint dependence in these series. In view of the relatively recent development of these systems spectral estimators, we also conduct Monte Carlo simulations across both low and high frequencies to assess properties of the estimator relative to established single equation techniques. New empirical estimates of the consumption function and tests of the PIH based on systems spectral regression methods are reported for U.S. aggregate consumption and income data over the period 1948–1993. The empirical results provide some evidence for the theoretical implications of the PIH.     

Autoregressive modelling of consumption,income, inflation and interest rate data: A multicountry study

In this study the question whether income, inflation and interest rate help to predict (Granger-cause) consumption of nondurables was analysed for USA, UK, FRG and France. Thereby a slightly modified variant of the stepwise autoregressive modelling approach suggested by Hsiao was extended to the four variables framework and applied to quarterly time series. The data indicate that at least one of the variables considered has predictive power for consumption. Thus, the permanent income hypothesis under rational expectation as formulated by Hall is rejected for the countries considered here.     

Permanent prices,expected price changes,and the demand for money

This paper investigates the empirical validity of the distinction between measured and permanent prices for cash balance decisions. The use of permanent prices has been advocated by Friedman over twenty five years ago, but the idea has received little attention in the literature. Using Canadian quarterly data, we find that the permanent price hypothesis yields meaningful estimates of the demand for money, but it does not appear to contribute significantly to our understanding of cash balance decisions. A number of assumptions about the relationship between the elasticities of income, price, and price change expectations are tested as well.     

RATIONAL CONSUMERS*

The life cycle/permanent income hypothesis (LCPIH) entails two postulates: People have rational expectations and people do not have problems with self‐control. If either or both of these postulates do not apply, we cannot obtain a testable implication for the LCPIH. We use Japanese representative panel data that include responses to self‐reported and retrospective questions in order to elicit behavior such as forward‐looking and self‐control problems. We test the rational expectations hypothesis and the LCPIH implication and find that rational consumers do not change their expenditure in response to expected income changes, which we restrict to fit the two LCPIH postulates.
