This paper confirms the positive empirical relationship between CAPM-implied target asset betas and bidder announcement returns originally documented by Dessaint et al. (Rev Financ Stud 34(1):1–66, 2021) for U.S. takeover bids. We successfully replicate the main regression results...

Does it pay to invest in green companies? In countries where a market for carbon is functioning, such as those within the European Union, our findings suggest that it should be beneficial. Using a sample of green and brown European firms, we initially demonstrate that green companies have...

This paper focuses on the task of detecting local episodes involving violation of the standard Itô semimartingale assumption for financial asset prices in real time that might induce arbitrage opportunities. Our proposed detectors, defined as stopping rules, are applied sequentially to...

Machine learning applications in finance commonly employ feature decorrelation techniques developed for generic statistical problems. We investigate whether this practice appropriately addresses the unique characteristics of financial data, where correlations often encode fundamental economic...

This paper explores the hypothesis that the returns of asset classes can be predicted using common, systematic risk factors represented by the level, slope, and curvature of the US interest rate term structure. These are extracted using the Nelson-Siegel model, which effectively captures the...

Purpose - Contrary to the developed markets, where ESG (environmental, social and governance) investing has received considerable attention, the extant literature in the context of emerging markets remains fragmented and scarce. To fill this gap, the study examines the financial performance of...

This paper examines efficient allocations in economies where consumers exhibit heterogeneous smooth ambiguity preferences and face model uncertainty with a common set of identifiable models. Aggregate endowment is ambiguous. We characterize economies where the representative consumer is of the...

Purpose - this paper adopts the mean-variance approach in optimizing portfolios within the Colombian capital market, a setting full of complications such as lack of liquidity and market concentration. It delivers actionable messages for emerging market stakeholders and formulates guidance aimed...

The COVID-19 pandemic potentially affected stock prices in two non-mutually exclusive ways: discount rates and cash flows. This paper focuses on the latter and analyzes it through the lens of an asset-pricing model. It shows how workplace resilience and financial resilience interacted and...

Economic expectations play a central role in financial markets, yet investors often disagree about the economy's future. This disagreement has long been viewed as a potential driver of asset prices, but it remains unclear whether it reflects mispricing or a priced source of risk. We address this...

This study comparatively evaluated the Capital Asset Pricing Model (CAPM), the Fama and French three-factor model (FF3), and the Fama and French five-factor model (FF5) in key US market sectors (finance, energy, and utilities). The goals were to optimize financial decisions and reduce valuation...

Heterogeneous beliefs among market participants can lead to questionable speculative trading that goes beyond any risk-sharing motives. We demonstrate that such unwarranted betting behavior in market equilibrium can be mitigated by introducing nonlinear pricing for ambiguous contracts, without...
