Cheap Talk under Ambiguity: The IPCC in Climate-Change Agreements.
Abstract : The Intergovernmental Panel on Climate Change (IPCC) has gained a central position on the report of scientific knowledge on climate change. This paper shows that the IPCC can take advantage of it to mitigate the inefficiency of the level of greenhouse gas emissions in international environmental agreements (IEA). I model an IEA as a game of contribution to a public bad. In making confidence statements over global warming predictions, the IPCC plays a cheap talk game with IEA participants. Under the assumption that players are maxmin expected utility maximisers I show that there is a unique sequential equilibrium in this game. This result backs up the idea that the IPCC could play a regulatory part in the management of climate change. In addition, it sheds new light on the role of strategic communication under ambiguity, supporting the view that it can contribute to restoring economic efficiency.

Cash Transfers, Unemployment and Informality: Evidence from South Africa's Child Support Grant
This paper explores the role of cash transfers in workers' allocation across the formal and informal sectors. I study the impact of an unconditional grant in South Africa paid to Black and Coloured mothers, for whom a significant share of employment is informal. I use discontinuous exposure for children of adjacent cohorts to identify the labor market effects on mothers of roughly one year of grant (400 $ 2010). I show that recipients of this grant are more likely to be unemployed when receiving the transfer. Five years after the grant has stopped, the employment probability is the same, but mothers who had received the grant are more likely to work in the formal sector. I present evidence that these are possibly the results of less binding liquidity constraints when unemployed, as the grant allows to spend more on transport when looking for a job.

Fathers' Multiple-Partner Fertility and Children’s Educational Outcomes
We find substantial effects of fathers' multiple-partner fertility (MPF) on children's long-term educational outcomes. We focus on the children in fathers’ “second families,” emphasizing the case in which the second families are nuclear families – households consisting of a man, a woman, their joint children, and no other children. We analyze outcomes for almost 80,000 children born in Norway in 1986-1988 who, until they were at least age 18, lived with both biological parents. This analysis cannot be done using existing US data sets. Children who spent their entire childhoods in nuclear families but whose fathers had children from another relationship living elsewhere were more likely to drop out of secondary school (24% vs 17%) and less likely to obtain a bachelor's degree (44% vs 51%) than children in nuclear families without MPF. Our probit estimates imply that the marginal effect of fathers' MPF is 4 percentage points for dropping out of secondary school and 5 percentage points for obtaining a bachelor's degree. Our analysis suggests that the effects of fathers' MPF are primarily due to selection.
