Pro‐environment behaviors, invasive plant management, and the gap between motivations for behavioral intention and action

Conservation Science and Practice, EarlyView.
Invasive plant species pose significant challenges to natural resources and communities around the world. However, invasive plant management may require different motivations than other pro‐environmental behaviors because mitigation of invasive plants often comes at high individual cost, has limited effectiveness when undertaken in isolation, and ...

Environmental Impact Shaping a Firm's Zero Leverage Decision: Analysing Debt Demand and Supply Determinants

European Financial Management, EarlyView.
ABSTRACT Zero‐leverage firms remain a puzzle in corporate finance. We propose a supply‐side mechanism linking environmental impact to debt access. Because creditors favour firms with high negative externalities and strong cash flows, environmentally friendly firms with high initial costs face tighter credit constraints.

When in Doubt, Tax More Progressively? Uncertainty and Progressive Income Taxation

International Economic Review, EarlyView.
ABSTRACT We study the optimal income tax problem under parameter uncertainty about household preferences and wage dynamics. We derive conditions characterizing how such uncertainty affects optimal tax policy. To quantify the effect, we estimate a life‐cycle model using US data and a Bayesian approach.

The Distributional Effects of Economic Uncertainty*

International Economic Review, EarlyView.
ABSTRACT We study the distributional implications of uncertainty shocks by developing a model that links macroeconomic aggregates to the US distribution of earnings and consumption. Our findings suggest that the fraction of low‐earning workers decreases initially, while the share of households reporting low consumption increases.
