abstract = {We examine the relationship between economic policy uncertainty and the release of climate change-related information as a representation of non-financial information. We argue that firms are likely to disclose their climate change-related information to gain ethical legitimacy, especially during uncertain times. Using the policy uncertainty measure from Baker, Bloom, and Davis (2016) and an extensive dataset from the CSRwire platform, we provide strong evidence that policy uncertainty is positively associated with releasing climate change-related news. Our findings are robust to alternative measures of policy uncertainty and when controlling for endogeneity. In a set of additional analyses, we show that the industries within which firms operate and their environmental performance are channels that explain the release of climate-related information. Taken together, our results highlight the role that climate change-related information may play in providing firms with ethical legitimacy and building trust among all stakeholders in times of political uncertainty.},

abstract = {We study the relationship between crude oil price volatility and corporate environmental performance. Using an extensive dataset from 32 countries consisting of 18,464 firm-year observations, we provide strong evidence that oil price volatility significantly increases firms' environmental performance. Our main inference is robust when using alternative measures of oil price volatility and environmental performance, alternative econometric specifications and samples, and several approaches to control for endogeneity. In a set of additional analyses, we first conduct a difference-in-differences analysis that exploits the Arab Spring as an exogenous oil price volatility increase and document a stronger relationship between oil price volatility and environmental performance in the aftermath of the Arab Spring. We second identify (i) capital expenditures and (ii) alternative energy importation as two mechanisms through which oil price volatility influences environmental performance. We finally show that national culture plays a significant role in moderating the relationship between oil price volatility and environmental performance. Taken together, our empirical findings highlight the role of economic uncertainty in affecting firms' environmental performance and provide significant contributions to management and policymakers.},

This result is remarkably robust after conducting a difference-in-differences analysis that exploits brokerage closures and mergers as an exogenous decrease in analyst coverage, as well as using an instrumental variable approach. The positive influence of analyst coverage on corporate environmental disclosure is particularly evident for firms that cause high environmental damage, firms with low information asymmetry and those followed by analysts with superior experience, accuracy and reputation. Taken together, our empirical findings provide new insights into the bright side effect of analyst coverage on corporate environmental-related activities.},

abstract = {To meet growing demands for information on their environmental impacts, firms may engage in selective disclosure by strategically reporting only a subset of relevant data. In this article, we draw out and problematize an antecedent to selective disclosure, public attention. Prior studies suggest that public attention brings scrutiny that reduces selective disclosure by increasing the risk of getting caught (the floodlight thesis). The impression management literature, however, suggests that public attention offers the possibility of broad-based image benefits from the disclosure of strategically filtered data (the spotlight thesis). Panel regressions with Trucost data from 2008-19 provide overall support for the spotlight thesis as well as a negative moderator, environmental damage. Results also point to an underlying mechanism: Companies receiving public attention disclose a larger number of environmental metrics, but not ones that, altogether, represent more environmental damage, a tactic that we call strategic fluffing.},

Fossil fuel free (FFF) financial products?which are portfolios that exclude companies involved in the production of oil, gas, and coal?have proliferated, initiating a debate on their financial and ecological implications for economic agents. This paper examines whether and the extent to which these financial products are immune to fluctuations in the price of fossil fuels. To do so, we empirically assess the daily effects of changes in oil, gas, and coal prices on returns on fossil fuel free indices provided by S&P. While we find no evidence that the FFF indices underperforms their conventional counterparts on average, the results from our model further show that the returns on FFF portfolios have more exposure to movements in fossil fuel prices than those on mainstream portfolios. The insights from our estimations have important implications for investors and other economic agents.},

To address this gap, our study examines the relationship between corporate environmental behavior and language structure around the world. Using a large dataset of 26,390 observations over the 2007-2015 period, we find that firms' environmental damages are lower where speakers are required to grammatically distinguish between future and present events (i.e., strong future time reference). Our findings suggest that perceiving future events as more distant and precise in time may help corporate managers better understand the consequences of environmental damages and take actions to reduce their impact. Language structure therefore appears to be a determinant of corporate environmental performance.},

We also show that high political stability significantly reduces CO2 emissions in the short run, but not in the long run. Our findings highlight the importance of these factors in reducing pollution worldwide and provide incentives for international regulators and policymakers toward stronger and mandatory decisions that positively evolve less politically stable and corrupt countries.},

Based on a sample of weekly returns on 1,850 U.S. firms over the period 2012â??2020, our econometric estimations report a positive relationship between investor attention to FFD and excess stock returns for U.S. fossil fuelâ??related firms. Therefore, contrary to what the FFD campaigners might expect, the stigmatization of the fossil fuel industry does not drive down the stock returns on fossil fuelâ??related firms.},

Our empirical analyses show that, on average, trading volumes fall significantly (between 4% and 10%) when maximum daily temperatures exceed 30 °C (86 °F). The observed negative association is remarkably robust to a battery of alternative analyses such as bin tests, event studies, and time-series regressions controlling for any seasonal effects and financial market conditions.

abstract = {The goal of this paper is to investigate forecast heterogeneity and time variability in the formation of expectations using disaggregated monthly survey data on macroeconomic indicators provided by Bloomberg from June 1998 to August 2017. We show that our panel of forecasters are not rational and are moderately heterogeneous and thus confirm that previously well-established results on asset prices hold for macroeconomic indicators. The estimation of our flexible hybrid forecast model - defined at any time as a combination of the extrapolative, regressive, adaptive and interactive heuristics - using the Bai and Perron (1998) methodology reveals a significant timedependence in the structural model with some inertia in extrapolative and adaptive profiles. Changes in the formation of expectations are triggered mostly by financial shocks, and uncertainty is dealt with by using complex processes in which the fundamentalist component overweighs chartist activity. Forecasters whose models combine different relevant rules and display high temporal flexibility provide the most accurate forecasts. Authorities can then stabilize the domestic markets by encouraging fundamentalists' forecasts through increased transparency policy.},

US public attention to Islamic terrorism is measured using Google Search Volume, which reflects active public attentiveness, and media coverage, which measures passive attentiveness. We test its effect on the stock returns of Islamic and conventional indices by using difference-in-difference analysis. The results indicate that US public attention to Islamic terrorism negatively affects US Islamic indices, suggesting that investors may make amalgams between terrorism and Islamic finance. These clichés may lead them to sell Sharia-compliant assets when US public attention to Islamic terrorism is high. Taken together, our findings provide new evidence and financial implications for investors and providers of Islamic financial products.},

Besides this novel model, our approach embodies several important features: we perform Lee and Mykland's (2012) non-parametric test procedure to filter out microstructure noise from observed exchange rates and extract jumps as the significant ?equilibrium? returns; various categories of information news from different geographical regions are exploited; the hypothesis of a leverage effect on foreign exchange jumps due to asymmetric volatility shocks is examined. We found that the most influential scheduled macroeconomic news are globally related to the US job markets, output growth indicators and public debt, whereas significant event news include announcements of bank failures and government rescue plans. Surprises impact Forex jumps for about one third as a result of rather pessimistic forecasts due to the crisis period analyzed. For most of the currencies the hypothesis that negative volatility shocks have a greater impact on volatility than positive shocks of the same magnitude is validated, reflecting markets' concern about the costs implied by central bank's stabilization policies. Our findings provide evidence that the major foreign exchange markets are not efficient.},
