This paper reviews a number of recent contributions that demonstrate that a blend of welfare economics and statistical analysis is useful in the evaluation of the citations received by scientific papers in the periodical literature. The paper begins by clarifying the role of citation analysis in...

We consider the decision of an agent with time inconsistent preferences to undertake an irreversible investment that yields an uncertain current benefit and a delayed cost. We show that, if the flow of information revealed between periods when the investment is postponed is sufficiently high,...

We analyze the decision of individuals with time inconsistent preferences who undertake irreversible activities yielding either a current cost and a future benefit or a current benefit and a future cost. We first show that, when benefits come earlier than costs, the individual faces a...

We investigate a novel dynamic choice problem in an experiment where emotions are measured through self-reports. The choice problem concerns the investment of an amount of money in a safe option and a risky option when there is a 'global risk' of losing all earnings, from both options, including...

We analyze the investment decision of a population of time inconsistent entrepreneurs who overweight current payoffs relative to future returns. We show that, in order to avoid inefficient procrastination, agents may find it optimal to keep optimistic priors about their chances of success and...

This Paper studies a model where individuals have imperfect self-knowledge and learning is costly. It shows that the endogenous decision to collect information before taking an action creates a systematic and testable bias in the aggregate behaviour of agents in the economy. More precisely,...

A vast literature has investigated the relationship between trust and aggregate economic performance. We investigate the relationship between individual trust and individual economic performance. We find that individual income is hump-shaped in a measure of intensity of trust beliefs available...

This Paper considers a time-inconsistent individual who has the ability to make promises that lead to a financial or reputation loss if broken. We first identify conditions under which promises made are kept, and conditions under which they are (partially) broken. Second, we endogenize the...

In this paper we organize the literature on the economics of terrorism around seven different topics, offering a comprehensive view of the literature with a view to identifying questions that remain unanswered. The chosen topic areas are: The Measurement of Terrorist Activity, The Nature of...

From the viewpoint of the independence axiom of expected utility theory, an interesting empirical dynamic choice problem involves the presence of a 'global risk', that is, a chance of losing everything whichever safe or risky option is chosen. In this experimental study, participants have to...
