Some information on the session logistics:
If not stated otherwise, the discussant is the following speaker, with the first speaker being the discussant of the last paper. The last speaker of each session is the session chair. (Exception: invited sessions)
Presenters should speak for no more than 20 minutes, and discussants should limit their remarks to no more than 5 minutes. The remaining time should be reserved for audience questions and the presenter’s responses. We suggest following these guidelines also in the (less common) 3-paper sessions in a 2-hour slot, to allow participants to move between sessions. Discussants are encouraged to avoid summarizing the paper. By focusing on a few questions and comments, the discussants can help start a broader discussion with the audience.
Only registered participants can attend this conference. Further information available on the congress website https://www.iseg.ulisboa.pt/en/event/iipf/ .

Optimal Fiscal Policy in the Presence of Consumption Externalities: The Case for a Universal Basic Income? Universitat de Girona, Spain We analyse optimal fiscal policy in an overlapping generations model with endogenous labour supply and savings, and two consumption externalities: aspirations and habits. Aspirations cause each generation’s consumption to influence the utility of the next, while habits imply that higher early-life consumption reduces the perceived utility of consumption in old age. To implement the social optimum, the government uses a positive tax on wages, and a subsidy on investments, received by the old. An additional positive (negative) transfer to the young (old) is required to attain the optimum when there is under-accumulation of capital at the decentralised equilibrium. When there is over-accumulation of capital, the sign of the transfers becomes unclear, and the possibility that both are positive arises. Numerical exercises reveal conditions under which equal transfers to all individuals, a Universal Basic Income (UBI), can be optimal. Our results reveal when UBI can effectively enhance welfare.
