This paper assesses the quantitative impact of ambiguity on historically observed financial asset returns and growth rates. The single agent, in a dynamic exchange economy, treats the conditional uncertainty about the consumption and dividends next period as ambiguous. We calibrate the agent's...

We estimate agents' expectations about future fundamentals using a dynamic stochastic generalequilibrium model augmented with anticipated shocks. Accounting for agents' expectations atthe business cycle horizon results in aggregate risk factor innovations that have significant explanatory power...

Climate science finds that the trend towards higher global temperatures exacerbates the risks of droughts. We investigate whether the prices of food stocks efficiently discount these risks. Using data from thirty-one countries with publicly-traded food companies, we rank these countries each...

We provide first-time evidence on whether market-wide physical or transition climate risks are priced in U.S. stocks. Textual and narrative analysis of Reuters climate-change news over 2000-2018, uncovers four novel risk factors related to natural disasters, global warming, international...

We construct novel proxies of physical and transition climate risks by conducting textual analysis of climate-change news over the period 2000-2018. This analysis uncovers four textual variables related to the topics of U.S. climate policy, international summits, natural disasters, and global...

We focus our work here on some very recent results obtained by Cherny and Madan on risk measures. They developed a rigorous mathematical framework for the study of coherent risk measures. The first sections mainly review the existing literature. We present it here for sake of completeness as...

We propose a statistical methodology to quantify the financial implications of tropical cyclone-related physical risks implied by climate change. To address the sensitivity of disaster intensity to climate change, we provide a Monte Carlo methodology to generate synthetic cyclones consistent...

Changes in credit supply induce large and frequent variations in households' access to unsecured debt. They generate a novel financial precautionary motive, which compounds the classical motive associated with idiosyncratic income risk, as borrowers accumulate risk-free bonds to hedge against...
