We consider the effect of an increase in the risk from pollution. We show that in the case of a flow pollution, when … the number of players is sufficiently large, the result of Bramoulle and Treich, showing that a marginal increase of risk … in the neighborhood of a risk-free world is welfare-improving, holds even when we consider non-marginal increases in risk …

-contingent consumer's surplus and the state-contingent marginal utility of wealth and a second term representing risk aversion. This … consumer's surplus is determined by the covariance between preferences and consumer's surplus and risk aversion. The sign of ….

We develop indices of Twitter-based Chinese Climate Uncertainty (TC-CU) and Climate Policy Uncertainty (TC-CPU). Our …, among many others. We find that TC-CPU is associated with future US climate uncertainty and attention measures while US …

We introduce learning in a dynamic game of international pollution, with ecological uncertainty. We characterize and … ecological uncertainty but they gain information (learn) about it. We then compare our learning model with the benchmark model of … full information, where players know the distribution of ecological uncertainty. We find that uncertainty due to …

This paper examines how cooperation in an insurance game depends on risk preferences and the riskiness of income. It … of the discount factor above which perfect risk sharing is self-enforcing. When agents face no aggregate risk, there is … of idiosyncratic and aggregate risk. In the case of exponential (isoelastic) utility, cooperation depends positively on …

We examine how policy uncertainty affects firm innovation and competitive dynamism. In R&D races, the gap in the rate … investment from policy uncertainty present an opportune window for laggards to challenge and overtake leaders. We present … evidence that policy uncertainty increases the rate of innovation by laggards relative to leaders and accelerates upward …
