The tractable general equilibrium model developed by Golosov et al. (2014), GHKT for short, is modified to allow for stock-dependent fossil fuel extraction costs and partial exhaustion of fossil fuel reserves, a negative impact of global warming on growth, mean reversion in climate damages,...

This article discusses the effects of taxation on the discrete choice of alternative projects. In particular, it is shown that if taxation affects the optimal timing of irreversible investment, then the discrete choice is distorted as well. This result has both methodological and political...

The macroeconomic effects on growth, investment and private sector employment of different ways of rolling back the welfare state are analysed. Cutting public spending on private goods induces a lower interest rate, a higher wage, a lower capital stock and a fall in employment. Cutting public...

This paper addresses the issue of how regulatory constraints affect firm s investment choices when the firm has an option to delay investment. The RPI-x rule is compared to a profit sharing rule, which increases the x factor in case profits go beyond a given level. It is shown that a pure price...

In this article we analyse the effects of different regulatory schemes (price cap and profit sharing) on a firm s investment of endogenous size. Using a real option approach in continuous time, we show that profit sharing does not affect a firm s start-up decision relative to a pure price cap...

This article discusses the effects of an asymmetric tax scheme on incremental and sequential investment strategies. The tax base is equal to the firm s return, net of an imputation rate. When the firm s return is less than this rate, however, no tax refunds are allowed. This scheme is neutral...

This article discusses the effects of corporate tax asymmetries under investment irreversibility. We introduce a tax scheme where the tax base is given by the firm's return net of a rate of relief. When the firm's return is less than the imputation rate, however, no tax refunds are allowed....

This article compares an ACE system with a CBIT system in an open economy. Using a realoption approach we show that, if a firm can decide when to invest, a tradeoff is found. According to traditional wisdom, a high-income firm investing in an ACE system faces a heavier tax burden at each...

If global warming is to stay below 2°C, there are four risks of assets stranding. First, substantial fossil fuel reserves will be stranded at the end of the fossil era. Second, this will be true for exploration capital too. Third, unanticipated changes in present or expected future climate...
