Mitigating policy uncertainty: What financial markets reveal about firm‐level lobbying
American Journal of Political Science, EarlyView.Abstract Elections can lead to substantial policy changes and, thus, are a significant source of risk. Firms can respond to such policy uncertainty by lobbying, but it is hard to quantify whether they do so and, if so, how much lobbying benefits them. We construct a new dataset and leverage investors’ expectations of variability in stock returns in the

Relativistic Black-Scholes model
, 2016 Black-Scholes equation, after a certain coordinate transformation, is equivalent to the heat equation. On the other hand the relativistic extension of the latter, the telegraphers equation, can be derived from the Euclidean version of the Dirac equation.

Financial Management, EarlyView.ABSTRACT Diversity, equity, and inclusion (DEI) is one of the most polarizing issues in business and society. Advocates claim that DEI enhances fairness, while critics argue it undermines meritocracy. The problems often stem from the practice of DEI—reducing it to demographic diversity—rather than its principle.

Specification Tests for Jump‐Diffusion Models Based on the Characteristic Function
International Statistical Review, EarlyView.Summary Goodness‐of‐fit tests are suggested for several popular jump‐diffusion processes. The suggested test statistics utilise the marginal characteristic function of the model and its L2‐type discrepancy from an empirical counterpart. Model parameters are estimated either by minimising the aforementioned L2‐type discrepancy or by maximum likelihood ...

CEO Narcissism and Related Party Transactions
Journal of Business Finance &Accounting, EarlyView.ABSTRACT We examine the association between CEO narcissism and the likelihood of engaging in related party transactions (RPTs) and its influence on the value implications of these transactions. Furthermore, we investigate the effect of board monitoring on the relationship between CEO narcissism and the value effects of RPTs. We find that CEO narcissism
