Studies of the crude oil market based on structural vector autoregressive (VAR) models typically assume a time-invariant model and transmission of shocks and possibly allow for heteroskedasticity by using robust inference procedures. We assume a heteroskedastic reduced-form VAR model with time-invariant slope coefficients and explicitly consider the possibility of time-varying shock transmission due ...
We present an economics framework appropriate to the exceptionally broad scope of the climate change problem. This considers that economic and social processes, particularly those involved in purposive transitions of energy technologies and systems, involve the interplay between three distinct domains of decision-making and associated actors. The first concerns small-scale and often short-term decision-making, ...
Over the past 20 years, China has granted a conspicuous amount of loans to African countries. New loan data show that compared to Western multilateral loans, Chinese loans have relatively high interest rates and shorter maturities, tend to be highly collateralized, and are volatile over time. Thus, Western loans are generally more likely to be in the economic interest of the borrowing country. Furthermore, ...
Adjusting green public support programmes to green premiums can reduce public spending, yet this is challenged by uncertainty. Underfunding green technologies can delay the green transition, and overfunding them can increase transition costs. Both risks of under- and overfunding can be reduced using responsive adjustments.
To reduce greenhouse gas emissions, many countries plan to massively expand wind power and solar photovoltaic capacities. These variable renewable energy sources require additional flexibility in the power sector. Both geographical balancing enabled by interconnection and electricity storage can provide such flexibility. In a 100% renewable energy scenario of twelve central European countries, we investigate ...
This paper provides a comprehensive evaluation of the world’s largest environmental tax reform. We compare carbon and air pollutant emissions of the German transport sector and synthetic counterfactuals following the 1999 eco-tax reform, and find average re- ductions in external damages of around 80 billion Euros. We further show that the eco-tax induced low-carbon innovation and document much stronger ...
This paper provides the most comprehensive assessment of how fuel taxation reduces climate and pollution externalities with a quasi-experimental evaluation of the world’s largest environmental tax reform. Leveraging multiple causal inference methods, we compare carbon and air pollutant emissions of the actual and counterfactual German transport sector following the 1999 eco-tax reform and demonstrate ...
