The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

The effect of addback statutes on CEO compensation

open access: yesAccounting &Finance, Volume 65, Issue 1, Page 793-818, March 2025.
Abstract Exploiting the adoption of addback statutes, which occurred at different times, as exogenous shocks to corporate taxable income, we examine the effect of tax policy changes on the compensation of chief executive officers (CEOs). We provide evidence that CEOs of firms headquartered in states affected by addback statutes experienced a decrease ...

Mitigating policy uncertainty: What financial markets reveal about firm‐level lobbying

open access: yesAmerican 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

Board Independence and Adjustment Speed of CEO Inside Debt

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT We find that firms with more independent directors adjust CEO inside debt towards an optimum more quickly. This effect is more pronounced in financially unconstrained, growth, and under‐levered firms, and also firms led by more powerful or overconfident CEOs.

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.

Specification Tests for Jump‐Diffusion Models Based on the Characteristic Function

open access: yesInternational 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 ...
