In the modern regulatory state, there is a serious tension between two indispensable ideas. The first is that it is important to measure, both in advance and on a continuing basis, the effects of regulation on social welfare, usually through cost-benefit analysis. The second idea, attributable...

Findings in behavioral science, including psychology, have been influencing policies and reforms in many nations. “Choice architecture” can affect outcomes even if material incentives are not involved. In some contexts, default rules, simplification, and uses of social norms have been found...

This paper shows that if an individual's health costs are U-shaped in weight with a minimum at some healthy weight level and if the individual has both self control problems and rational motives for over- or underweight, the optimal paternalistic tax on unhealthy food mitigates the individual's...

It has been argued that hyperbolic discounting of future gains and losses leads to time-inconsistent behavior and thereby, in the context of health economics, not enough investment in health and too much indulgence of unhealthy consumption. Here, we challenge this view. We set up a life-cycle...

The author redefines utility in cardinal terms based on maximum willingness to pay. The proposed definition includes reference points for the agent's income and needs, which is key to framing consumption in terms of gain-loss prospects. The proposed framework is robust because it resolves...

This paper argues that thresholds in financial contracts act as implicit nudges in consumers’ decisions. Exploiting a regulatory change to credit card minimum payments in Mexico, we find that a one percentage point change in minimum payments leads to a 0.87 pp change in actual payments, both...

Many human decisions, ranging from the taking of loans with compound interest to fighting deadly pandemics, involve phenomena that entail exponential growth. Yet a wide and robust body of empirical studies demonstrates that people systematically underestimate exponential growth. This phenomenon,...

The study tries to recognize the behaviour of the consumer with respect to the opportunity cost and marginal benefit associated with the commodity. The research tries to evaluate the factors and identify behavioural traits of consumers if they exist in decision making. The study also tries to...

Does salient information on social media influence individuals' economic decisions and beliefs? Using aggregated data from Facebook and a difference-in-differences strategy, I show that individuals who are socially connected to someone affected by Hurricane Harvey are more likely to purchase...

Assuming that agents' preferences satisfy first-order stochastic dominance, we show how the Expected Utility paradigm can rationalize all optimal investment choices: the optimal investment strategy in any behavioral law-invariant (state-independent) setting corresponds to the optimum for an...
