Helping policymakers with difficult decisions in deep uncertainty

sbr-scenarios

Severin Borenstein at UC Berkeley argues against the “try everything” approach to searching for solutions to mitigating greenhouse gas emissions. But he is confusing situations with relatively small incremental consequences (even the California WaterFix is “small” compared to potential climate change impacts.)

Instead, when facing a potentially large catastrophic outcome for which the probability distribution is completely unknown, we need a different analytic approach than a simple cost-benefit analysis based on an “expected” outcome.

We need to be looking for what decision pathways lead us to the situations create the most vulnerability, not for which one has the “optimal outcome.” Policymakers and stakeholders looking desperately for any solution intuitively get the notion of robust decisionmaking, but are not receiving much guidance about how to best pursue this alternative approach.  Economists need to lead the conversation that changes the current misleading perspective.

Why coal isn’t coming back–cheap renewables

It’s not environmental regulation now that is leading to the demise of the coal industry–it’s the cheaper cost of alternatives. Rather than “bring back coal mining jobs,” we should focus on how we retrain and relocate those displaced workers. And we need to look for new industries that may thrive in “coal country.”
