Building on previous research in economics and psychology, we propose that the costliness of initial prosocial behavior positively influences whether that behavior leads to consistent future behaviors. We suggest that costly prosocial behaviors serve as a signal of prosocial identity and that people subsequently behave in line with that self-perception. In(More)
Fibrosis is characterized by elevated transforming growth factor (TGF ) signaling, resulting in extracellular matrix accumulation and increasedPAI-1 (plasminogen activator inhibitor) expression. PAI-1 induces the internalization of urokinase plasminogen activator/receptor and integrin v 3 from the cell surface. Since increased v 3 expression correlates with(More)
Fibrosis is characterized by elevated transforming growth factor beta (TGFbeta) signaling, resulting in extracellular matrix accumulation and increased PAI-1 (plasminogen activator inhibitor) expression. PAI-1 induces the internalization of urokinase plasminogen activator/receptor and integrin alphavbeta3 from the cell surface. Since increased alphavbeta3(More)
We conduct a controlled lab-field experiment to directly test the short-run spillover effects of one-off financial incentives in health. We consider how incentives affect effort in a physical activity task – and then how they spillover to subsequent eating behaviour. Compared to a control group, we find that low incentives increase effort and have little(More)
We propose that individuals use anger strategically in interactions. We first show that in some environments angering people makes them more effective in competitions, whereas in others, anger makes them less effective. We then show that individuals anticipate these effects and strategically use the option to anger their opponents. In particular, they are(More)
In a tedious real effort task, subjects know that their piece rate is either low or ten times higher. When subjects are informed about their piece rate realization, they adapt their performance. One third of subjects nevertheless forego this instrumental information when given the choice — and perform stunningly well. Agents who are uninformed regarding(More)
The paper reports the results of two experiments in which people who first made an immoral choice were then more likely to donate to charity than those who did not. In addition, those who knew that a donation opportunity would follow the potential moral transgression were more likely to behave immorally than those who were not told of the donation option.(More)
We study the role of heuristic versus deliberative processing in intertemporal choice. Using studies in the Democratic Republic of Congo and an online labor market, we show that waiting periods –designed to prompt deliberation by temporally separating news about choice sets from choices themselves– can shift individuals away from decisions consistent with(More)
There is growing interest in the use of loss contracts that offer performance incentives as upfront payments that employees can lose. Standard behavioral models predict a tradeoff in the use of loss contracts: employees will work harder under loss contracts than under gain contracts; but, anticipating loss aversion, they will prefer gain contracts to loss(More)
