This paper deals with three aspects of spectacular oil price episodes such as the one witnessed in 2008. First, the concept of temporary explosiveness is proposed as an empirical method for capturing this type of behavior. The application of a recently proposed recursive unit root test shows...

In a continuous-time framework we study the technology and investment choice problem of a continuous co-digestion biogas plant dealing with randomly fluctuating relative convenience of input factor costs. Input factors enter into the productive process together mixed according to a given initial...

The paper studies the interaction between cyclical uncertainty and investment in a stochastic real option framework where demand shifts stochastically between three different states, each with different rates of drift and volatility. In our setting the shifts are governed by a three-state Markov...

This paper examines the impact of Knightian uncertainty upon optimal climate policy through the prism of a continuous-time real option modelling framework. We analytically determine optimal intertemporal climate policies under ambiguity. Additionally, numerical simulations are provided to...

The role of product market reforms in achieving the objective of higher employment and growth has recently received much attention amongst academics. The aim of this paper is to analyse some of the channels through which cross-market effects come about and to assess their policy relevance. The...

The possibility of low-probability extreme events has reignited the debate over the optimal intensity and timing of climate policy. In this paper we therefore contribute to the literature by assessing the implications of low-probability extreme events on environmental policy in a continuous-time...

This paper, first, empirically investigates European emission allowance (EUA) prices and, second, evaluates emission trading as a policy measure. Applying combined jump GARCH models yields strong evidence of conditional jump behavior. This implies that EUA prices are subject to unexpected...

This paper shows that taxes which are understood to be neutral with respect to the marginal investment decisions may be distortionary with respect to entrepreneurial decisions. In particular, we apply an intertemporal model to show that a comprehensive income tax is distortionary unless all...

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...

The standard literature on working time has modelled the decisions of firms in a deterministic framework in which firms can choose between employment and overtime (given mandated standard hours). Contrary to this approach, we consider the impact of uncertainty and real options on the decision of...
