Rates Of Time Preference

Rates of time preference (RTPs) of rural households in Indonesia, Zambia and Ethiopia have been measured using hypothetical questions about preferences for current versus future consumption. In general, the rates were found to be very high. Factors influencing or correlated with the personal rates of time preference were investigated through regression methods. OLS was the technique used in the estimation. Market imperfections, particularly in credit and insurance markets lead to variation in RTPs. Poverty in assets, or cash liquidity constraints, was leading to or correlated with higher rates of time preference. The poor are, therefore, less likely to invest in environmental conservation. In Zambia, independent estimates of risk preferences were made. More risk-averse people tended to have lower RTPs. The results support the hypothesis that poverty and/or liquidity scarcity lead to high RTPs. Poverty reduction may thus reduce the RTPs of the poor and reduce the 'intertemporal externality' due to high RTPs. The high average RTPs indicate, however, that complementary policies may be needed to ensure sufficient levels of investment in conservation. Another logical implication is that institutionalization of private property rights may not be a sufficient tool to initiate sustainable resource management.

Rates Of Time Preference

In this paper, the author studies the association between religious affiliation and investment income as a proxy for individual rates of time preference, defined as the propensity to sacrifice present satisfaction in the anticipation of increasing future satisfaction. Data from the 2001 Census of the Canadian population is used to look at how religious affiliation is associated with the proportion of income coming from investments (a proxy for past rates of time preference) for individuals of working age (15-64). Two models (OLS and logistic) are used in order to compare by religious affiliation the magnitude of the proportion of income attributable to investments and the propensity to invest. Although there are a few exceptions in terms of cross-regional heterogeneity, individuals of Jewish affiliation tend to receive more investment income (as a proportion of their income) than Protestants, who tend to receive more than Catholics. As for the propensity to obtain any investment income, the results are more nuanced although a similar pattern can be observed. The contribution of this paper is to quantitatively assess the association of religious affiliation with time preference through the use of an investment income variable, an endeavour which has not been undertaken so far and which complements the literature on the economic outcomes of religion and the sociological determinants of time preference.Dans cet article, l’auteur étudie l’association entre l’affiliation religieuse et les revenus d’investissement comme une approximation des taux individuels de préférence temporelle, définie comme la propension à sacrifier la satisfaction présente dans l’attente d’une satisfaction future croissante. Des données du recensement de la population canadienne de 2001 sont examinées pour mesurer comment l’appartenance religieuse est associée à la proportion de revenus provenant d’investissements (une approximation des taux passés de préférence temporelle) pour les personnes en âge de travailler (15-64 ans). Deux modèles (MCO et logistique) sont utilisés afin de comparer par appartenance religieuse l’ampleur de la proportion de revenu attribuable aux investissements et la propension à investir. Bien qu’il y ait quelques exceptions en termes d’hétérogénéité interrégionale, les individus d’affiliation juive ont tendance à recevoir plus de revenus d’investissement (en proportion de leurs revenus) que les Protestants, qui ont tendance à recevoir plus que les Catholiques. En ce qui concerne la propension à obtenir des revenus d’investissement, les résultats sont plus nuancés, bien qu’un schéma similaire puisse être observé. La contribution de ce document est d’évaluer quantitativement l’association entre l’appartenance religieuse et la préférence temporelle en utilisant une variable de revenu d’investissement, un effort qui n’a pas été entrepris jusqu’à présent et qui complète la littérature sur les résultats économiques de la religion et les déterminants sociologiques de la préférence temporelle.
