  Some economics of green finance
  

  Abstract: Climate finance is a poor substitute for state-controlled climate policies within the state jurisdiction. Responsible finance principles should be based on an internal carbon price, to be used by responsible investors, financial intermediaries and central banks. Other covered topics for this talk include greening recovery plans, sharing the risk of the cost of the ecological transition, reshaping the composition of equity market indices, a discussion of the efficacy and role of the divestment movement and a discussion of the role of central banks.

  Christian Gollier is an internationally-renowned professor of decision theory under uncertainty, with applications in climate economics, finance and cost-benefit analysis and a special interest in long term (sustainable) effects. He is a fellow of the Econometric Society, and received an ERC Advanced Grant in 2011. He founded the Toulouse School of Economics alongside Jean Tirole, where he has served as director (2007-2015), vice-president (2017), and director again since December 2017. He is currently president-elect of the European Association of Environmental and Resource Economists (EAERE). In recent years, he has held visiting sabbatical positions at Harvard (2013) and Columbia (2015-2016). He has published more than 100 articles in top journals in economics, is one of the lead authors of the last two IPCC reports, and is the author of several books published by MIT Press, Princeton University Press and Columbia University Press. His most recent outreach book in French (Le climat après la fin du mois, PUF, 2019) on the importance of acting to mitigate climate change, has met with wide success in France, and is currently under translation into English.

  Signalling through carbon disclosure

  Abstract: We estimate effects of voluntary and mandatory disclosure of carbon emissions on stock returns, volatility, and turnover. We find that voluntary disclosure of scope 1 emissions by companies results in lower stock returns relative to non-disclosing companies. However, a cost of disclosing emissions is increased divestment by institutional investors. We also find that U.K. mandatory carbon disclosure rules for publicly traded companies resulted in lower stock-level uncertainty. The effect of these mandatory disclosure rules also spilled over into other markets, especially those with close geographic and economic proximity, and companies in the same industry.

  Environmental finance: research challenges and opportunities following the COVID-19 recovery

  Abstract: The year 2020 has shown the nature of global interconnected risks: the outbreak of the COVID-19 pandemic has had significant social and economic impacts globally. Current fiscal stimulus packages already greatly surpass the rescue packages during the 2007/2008 Financial Crisis and are meant to revive failing economies. However, the impacts from COVID-19 are likely not an isolated occurrence, with societies globally facing significant future risks from the impacts of climate change and resource depletion. This presentation takes a critical look at progress towards achieving sustainable development and examines challenges and opportunities for environmental finance research in the post-pandemic era.

  Martina Linnenluecke leads the Centre for Corporate Sustainability and Environmental Finance at Macquarie University which brings together an interdisciplinary team of leading experts in the areas of corporate sustainability and environmental finance. The Centre has worldwide reach and impact by demonstrating a financial case for action on environmental and social change, with projects focusing on stranded asset risk, ESG investing, climate policy impacts, as well as adaptation and resilience to global environmental change. Professor Linnenluecke's research interests focus on the strategic and financial implications of corporate adaptation and resilience to climate change impacts. Her expertise in the field has been demonstrated through a number of prestigious awards, such as the Carolyn Dexter Best International Paper Award at the Academy of Management Conference, the leading conference in the management field. She is the author of the book "The Climate Resilient Organization", and has extensive experience in working with government and industry related to organisational climate adaptation strategies, assessments and planning. Professor Linnenluecke is a contributing author to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6 WGII).

  Climate risk: the price of drought

  Abstract: We document a significant positive relation between drought risk and the cost of equity capital. Our estimation shows that the cost of equity capital is 92 basis points higher for firms affected by severe drought conditions. We provide evidence that when firms are affected by droughts, firms with higher local institutional holdings exhibit a higher cost of equity capital. This result supports the well-known local bias of institutional investors, and suggests that diversification cannot fully eliminate the loss in wealth caused by droughts. Consistent with theoretical predictions, we find that drought duration and drought intensity further increase a firm’s risk premium. However, for firms with diversified cash flows/investments, geographically dispersed business operations, and high cash holdings, the impact of drought on the expected return is significantly lessened. Overall, our findings show that investors require a higher rate of returns on firms affected by droughts and offer implications on how firms can mitigate the impact of droughts on their cost of capital

  Cameron Truong is a Professor in the Department of Accounting at Monash University. Cameron has published in journals such as Journal of Accounting Research, The Accounting Review, The Review of Accounting Studies, Contemporary Accounting Research, Auditing: a Journal of Practice and Theory, Journal of Business Finance and Accounting, Financial Analyst Journal, Journal of Financial Markets, Journal of Banking and Finance, Journal of Financial Research, among others. Cameron current research focuses on climate risk, pandemic-induced risk, and disaster risk in capital markets.

  Structured climate financing: valuation of CDO's on inhomogeneous asset pools

  Abstract: Recently, a number of structured funds have emerged as public-private partnerships with the intent of promoting investment in renewable energy in emerging markets. These funds seek to attract institutional investors by tranching the asset pool and issuing senior notes with a high credit quality. Financing of renewable energy (RE) projects is achieved via two channels: small RE projects are financed indirectly through local banks that draw loans from the fund's assets, whereas large RE projects are directly financed from the fund. In a bottom-up Gaussian copula framework, we examine the diversification properties and RE exposure of the senior tranche. To this end, we introduce the LH++ model, which combines a homogeneous infinitely granular loan portfolio with a finite number of large loans. Using expected tranche percentage notional (which takes a similar role as the default probability of a loan), tranche prices and tranche sensitivities in RE loans, we analyse the risk profile of the senior tranche. We show how the mix of indirect and direct RE investments in the asset pool affects the sensitivity of the senior tranche to RE investments and how to balance a desired sensitivity with a target credit quality and target tranche size.

  Hedging climate change

  Abstract: We propose and implement a procedure to dynamically hedge climate change risk. To create our hedge target, we extract innovations in climate news series that we construct through textual analysis of high-dimensional data on newspaper coverage of climate change. We then use a mimicking-portfolio approach to build climate change hedge portfolios using a large panel of equity returns. We discipline the exercise by using third-party ESG scores of firms to model their climate risk exposures. We show that this approach yields parsimonious and industry-balanced portfolios that perform well in hedging innovations in climate news both in sample and out of sample. The resulting hedge portfolios outperform alternative hedging strategies based primarily on industry tilts. We discuss multiple directions for future research on financial approaches to managing climate risk.

  Testing the dismal theorem

  Abstract: Weitzman’s Dismal Theorem has that the expected net present value of a stock problem with a stochastic growth rate with unknown variance is unbounded. Cost-benefit analysis can therefore not be applied to greenhouse gas emission control. We use the Generalized Central Limit Theorem to show that the Dismal Theorem can be tested, in a finite sample, by estimating the tail index. We apply this test to three integrated assessment models commonly used to estimate the social cost of carbon, and to previously published estimates. Two of the three models do not support the Dismal Theorem, but the third one does for low discount rates. The meta-analysis cannot reject the Dismal Theorem.
