SUMMARY:Susana CAMPOS-MARTIN (Oxford University) "Novel Global and Regional Risk Factors"
DESCRIPTION:Finance & Financial Econometrics : \nTime: 09.30 am\nDate: 23th of May 2023\nRoom 3001 \nSusana CAMPOS-MARTIN (Oxford University) “Novel Global and Regional Risk Factors” \nAbsract : A global factor may not be enough to capture worldwide common variation in financial volatilities or correlation of shocks to those volatilities. A two-factor model of financial volatilities is developed to measure the common volatility shocks to sovereign bond indices. We observe that their volatilities are driven by not only a global but also a group-specific\, presumably European\, volatility factor. Some of the events that would have been identified as global\, such as presidential elections\, turn out to have a much lower impact globally. Other events have an amplified effect when group-specific common effects are allowed. European countries are much more impacted by shocks such as the 2016 European Union membership referendum in the United Kingdom than the rest of the world. While the global volatility factor seems to predict global economic crises\, the regional factor shows predictive power for the European sovereign debt crisis. \nJoint work with R.F.

SUMMARY:Gabriele MINGOLI (Vrije Universiteit Amsterdam) "Non-Stationary Factors for Common Bubbles"
DESCRIPTION:Finance & Financial Econometrics : \nTime: 10:20 am\nDate: 23th of May 2023\nRoom 3001 \nGabriele MINGOLI (Vrije Universiteit Amsterdam) “Non-Stationary Factors for Common Bubbles” \nAbstract : This paper proposes a novel multivariate time-series model with common stochastic trends and locally explosive mixed causal non-causal dynamics while allowing for idiosyncratic non-stationarities and explosive episodes. This model allows the description of common bubbles in high dimensional settings through common factors\, with every non-stationary process that experience local explosive episodes\, either common or idiosyncratic\, being modeled according to an additive structure between a fundamental value and a bubble component. We provide sufficient conditions for consistency of the estimated factors and parameters. A Monte Carlo simulation confirms the good finite sample properties. An empirical study shows that our approach models correctly bubbles present in the monthly prices of stock from the energy sector. \nOrganizers:\n\nJean-Michel ZAKOIAN (CREST) \nSponsors:\nCREST \n

SUMMARY:Chiara Colesanti (University of Zurich - LSE\, Grantham Institute)  "A study of nature risk pricing"
DESCRIPTION:Quantitative Sustainable Economics and Finance \nTime: 11.20 am\nDate: 23th of May 2024\nRoom 3005 \nChiara Colesanti (University of Zurich – LSE\, Grantham Institute) “A study of nature risk pricing” \nAbstract :We introduce a novel dataset provided by S&P Global that contains company-level information on nature dependence and nature impact. Based on these metrics we construct nature and climate factors. To test whether these factors earn a risk premium\, we rely on a factor-mimicking portfolio approach. We show that whether investors require a premia depends on the specific nature and climate risk considered\, which stressed the importance of using granular information when looking at these risks. \nOrganizers:\n\nPeter TANKOV (CREST) \nSponsors:\nCREST \n

SUMMARY:Emanuele Campiglio (University of Bologna) "Warning words in a warming world"
DESCRIPTION:Quantitative Sustainable Economics and Finance \nTime: 12.10 pm\nDate: 23th of May 2024\nRoom 3005 \nEmanuele Campiglio (University of Bologna) “Warning words in a warming world” \nAbstract :We study climate-related central bank communication using a novel dataset containing 32\,359 speeches from 131 central banks over the 1986-2021 period. We employ natural language processing techniques to identify three evolving climate-related narratives centered around ‘sustainable development’\, ‘green finance’ and ‘climate-related financial risks’. We find central bank public communication strategies to be primarily driven by underlying institutional factors. Finally\, we study the impact of communication on equity prices and find that firms characterized by better environmental scores benefit from the more frequent and intense engagement of central banks on climate-related topics. \nOrganizers:\n\nPeter TANKOV (CREST) \nSponsors:\nCREST \n
