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...

We study how international environmental agreements can take advantage of domestic time-inconsistency problems. Policymakers often prefer future policies to be sustainable, but are tempted to invest less when being in office. We find the equilibrium number of signatory countries to be higher...

We have built and investigated analytically and numerically a differential game model of Cournot oligopoly with consideration of pollution, network structure, and continuous updating. Up to this time, games with network structure and continuous updating were considered separately. We analyzed...

Hyperbolic discounting, a key determinant of intertemporal behavior, captures individuals' preferences for smaller immediate rewards over larger delayed ones. This study examined how hyperbolic discounting influences investment loss tolerance using a large-scale dataset of Japanese investors....

Bolivia has achieved noteworthy success over the past 15 years in raising incomes, reducing poverty, and maintaining macroeconomic stability by deploying commodity revenues to finance transfers, public investment, and state-led development, using an exchange rate peg as a policy anchor. However,...

We develop a model to analyze policymakers’ incentives to install policy rules, comparing the case of no rule with a binding and a contingent policy rule that allows policymakers to suspend the rule in response to a sufficiently large shock. First, abstracting from political polarization, we...

Anecdotally, physical activity appears to be a textbook example of time inconsistency, which is the failure to follow through on ex-ante preferences and plans. Interestingly, our longitudinal survey finds that, over a fortnight, exercising more than preferred/planned is actually more prevalent...

This paper investigates time inconsistencies in food consumption based on a field experiment at a college canteen where participants repeatedly select and consume lunch menus. The design features a convex non-monetary budget in a natural environment and satisfies the consume-on-receipt...

We take into account that envy (relative consumption concerns) is more pronounced in the present than in the future. We consider a Ramsey-type model in which agents differ only in their initial capital endowments but are identical in their exogenous parameters. Agents' preferences exhibit...

The commitment ability of governments is neither infinite nor zero but intermediate. In this paper, we determine the commitment ability that a government needs to implement a unique equilibrium outcome and rule out self-fulfilling expectations. We show that, in a large class of static...
