The risk of catastrophes is one of the greatest threats by climate change. Yet, the most common Integrated Assessment Models produce the counterintuitive result that a higher concern about climate change risks does not lead to stronger near-term abatement efforts. This paper probes whether this...

This paper provides a modelling framework for evaluating the exchange rate dynamics in target zone regime with undisclosed bands. We generalize the literature to allow for asymmetric one-sided regimes. Market participants' expectation formation about the undisclosed band change as they learn...

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...

Hong Kong's currency is pegged to the US dollar in a currency board arrangement. In autumn 2003, the Hong Kong dollar appreciated from close to 7.80 per US dollar to 7.70, as investors feared that the currency board would be abandoned. In the wake of this appreciation, the monetary authorities...

This paper provides a modelling framework for evaluating the exchange rate dynamics of a target zone regime with undisclosed bands. We generalize the literature to allow for asymmetric one-sided regimes. Market participants' beliefs concerning an undisclosed band change as they learn more about...

This paper presents a theoretical framework analysing the signalling channel of exchange rate interventions as an informational trigger. We develop an implicit target zone framework with learning in order to model the signalling channel. The theoretical premise of the model is that interventions...

The quintessence of recent natural science studies is that the 2°C target can only be achieved with massive emission reductions in the next few years. The central twist of this paper is the addition of this limited time to act into a non-perpetual real options framework analysing optimal...

As an incentive to increase high-impact investment and boost growth, the German Federal Government is planning to introduce a targeted temporary super depreciation allowance to support much-needed green and digital transitions. Using a calibrated multi-sector DSGE model, we find that the...

The semiconductor industry stands at the center of the intensifying Sino-American trade conflict. Employing a multi-country, multi-sector general equilibrium modeling framework with imperfect competition and heterogeneous firms, we perform qualitative and quantitative analyses of protectionist...
