Sentiment risk premia in the cross-section of global equity
This paper applies a recently developed sentiment proxy to the construction of a new risk factor and provides a comprehensive understanding of its role in sentiment-augmented asset pricing models. We find that news and social media search-based indicators are significantly related to excess returns of international equity indices. Adding sentiment factors to both classical and more recent linear factor pricing models leads to a significant increase in their performance. When it is estimated using the Fama-MacBeth procedure, our sentiment-adjusted pricing model implies positive (negative) estimates of the risk premium for positive (negative) sentiment factors. We further differentiate between developed and emerging markets and uncover different patterns of return reversals / persistence in the long-term. Our results contribute to the explanation of global cross-sectional average excess returns and are robust to augmenting the model with fundamental factors, momentum, idiosyn! cratic vo latility, skewness, kurtosis, and the returns on international currencies. When compared to competing definitions of sentiment factors popular in the literature, our novel sentiment risk variable turns out to be superior in terms of predictive power.

Abstract
Environmental, social, and governance (ESG) factors have acquired great relevance for investors in recent years. This paper examines the intersection between ESG and crowdfunding, one of the most popular types of fintech. Using data on the population of 508 platforms established in the 37 OECD countries between 2007 and 2020, we document that platforms with higher levels of ESG criteria are more likely to survive over time. Results are robust to different measures of ESG and endogeneity concerns. The importance of ESG criteria depends on cultural differences, as it is more pronounced for those platforms operating in countries where the level of power distance is lower.
