Carbon pricing regulates emission flows and collects rents from underlying fossil resource stocks. The resulting investment shift implies lower climate policy costs and improved welfare if capital is underaccumulated. We prove that under emission trading, such a beneficial macroeconomic...

We study how the introduction of carbon taxes in a closed economy propagate in a credit portfolio and precisely describe how carbon taxes dynamics affect the firm value and credit risk measures such as probability of default, expected and unexpected losses.We adapt a stochastic multisectoral...

Climate change poses an existential threat. The authors argue that carbon pricing and green research and development (R&D) support are good economics, but their implementation can be improved. Even if carbon prices are generalized and given more substance, green R&D is still likely to be smaller...

This paper presents a model in which cash holding imposes a negative externality because it worsens future adverse selection in markets for long-term assets, which impairs their role for liquidity provision. Adverse selection worsens when potential sellers of long-term assets hold more cash...

"Standard" environmental economics considers emissions trading to be the most effective and efficient policy instrument to meet the emission target. However, a popular view is that tradeable permits should be part of a policy portfolio, including other instruments, to reach this goal. Support...

We study the optimality of taxing capital income according to a Rate-of-Return Allowance proposed by the Mirrlees Review. In a mean-variance framework the optimal tax on risk-free returns is zero with constant returns to scale in private investment, but positive with decreasing returns to scale,...
