Working papers

“Sceptic priors and climate policy.” Under review.

How much evidence would it take to convince climate sceptics that they are wrong about global warming? I explore this question within a Bayesian framework. I consider a group of stylised sceptics and examine how these individuals update their beliefs in the face of current and continuing climate change. I find that available evidence in the form of instrumental climate data already tends to overwhelm all but the most extreme priors. The resulting posterior distributions of climate sensitivity correspond closely to existing estimates from the scientific literature. The updated beliefs of most sceptics are thus consistent with a carbon price that is substantially greater than zero. However, belief convergence is a non-linear function of prior strength, so that it become increasingly difficult to convince the marginal sceptic. I conclude by discussing the general conditions for consensus formation under Bayesian learning, its relevance to our current policy impasse, and offer some remarks about finding common ground in the future.

“Hydro power. Market might.”

Hydropower is the world’s foremost source of non-fossil fuel energy. It is also characterised by a unique set of production features that have the potential to greatly simplify economic questions related to firm behaviour and output. I demonstrate this principle using a novel data set of Norwegian hydropower firms, reservoirs and electricity flows. Pairing these data with quasi-experimental variation in local market power—due to market reconfiguration and binding transmission constraints—my empirical setting is sufficiently detailed to derive generalizable insights about firm behaviour without the need for additional structure or model restrictions. I show that increased market power causes firms to withhold production during inelastic demand periods, thereby yielding higher profits and driving up consumer prices. A larger takeaway is that even our most advanced markets may be susceptible to price distortions and welfare losses under fairly common conditions. (New version available soon.)
