This paper charitably develops a possible metaphysical argument against usury, as a common ground on which theology and economics can consider the issue. The metaphysical framework is derived from Anselm's Augustinian-Platonist metaphysics of participation whereby all goods are good through the...

This report estimates the "social rate of time preference" (SRTP) for New Zealand public policy appraisal using a Ramsey equation. It uses the Weitzman (1998) method to derive a declining discount rate schedule of 2% (real) for years 1-30, 1.5% for years 31-100, and 1% for years 101 on. The...

We study a discrete-time optimal growth model with endogenous discounting. The discount factor may depend on both consumption and the capital stock, and intertemporal utility is modeled as a discounted sum of instantaneous utilities, with the sum of discount factors equal to one. We show that...

We propose a novel way of measuring trust in institutions, which draws on the experimental method used to elicit time preferences. Our measure is provided in the meaningful metric of the subjective probability of trustworthiness of the trustee. In a lab‐in‐the‐field setting in the...

Many risk and time elicitation designs rely on choice lists that aim to capture a switch point. A choice list for a respondent typically contains two switch point defining choices; the other responses are dominated in the sense that the preferred option could be inferred from the switch point....

The effects of mindfulness interventions on food purchases and consumption are popular topics. Recent studies focus on mindfulness interventions that target overweight and obese populations. We measure the effects of a guided 5-minute body scan mindfulness intervention on 'healthier' food...

The Ramsey (1928) equation decomposes the real discount rate into the pure rate of time preference plus a term that accounts for the changing marginal utility of consumption. Discussions about the appropriate discount rate to apply in Cost Benefit Analysis sometimes refer to variations induced...

Consumers often exhibit behavioral cycles with alternating abstinence and indulgence over time. In the framework of tempting good consumption under limited willpower, we develop a simple model of the self-control cycles. To do so, based on the empirically relevant property of self-control, we...

We study the effects of envy (relative consumption concerns), drawing on evidence that preferences typically exhibit present bias. We employ a Ramseytype model with agents who differ in initial capital endowments and account for present-biased envy: agents are naive and care about how their...

Luckman et al. (2018) experimentally tested the conjecture that a single model of risky intertemporal choice can account for both risky and intertemporal choices, and under the conditions of their experiment, found evidence supporting it. Given the existing literature, that is a remarkable...

This paper studies a dynamic quantile model for intertemporal decisions under uncertainty, in which the decision maker maximizes the τ-quantile of the stream of future utilities, for τ ∈ (0,1). We present two sets of contributions. First, we generalize existing results in directions that are...

We study all theories of justice that disentangle ethical views on intergenerational discounting and intergenerational inequality. Each “modular” social welfare function is uniquely identified by a time-discounting function—capturing attitudes toward time—and an aggregator function—...

Qualitative self-assessments of economic preferences have recently gained popularity, often supported by experimental validation, a method that links them to choices in incentivized elicitations. We illustrate theoretically that experimental validation may fail to produce reliable new measures....

We study how the separation of time and risk preferences relates to a property called Stochastic Impatience. We show that, within a broad class of models, Stochastic Impatience holds if and only if risk aversion and the inverse elasticity of intertemporal substitution are sufficiently close. In...

This study investigates the dynamic impact of population aging on consumption preferences in China, a critical area given consumption's role in global economic growth and the country's accelerating demographic shifts. Utilizing pooled panel data from the 2015, 2017, and 2019 China Household...
