I follow Matthew Kahn’s, USC economics chair, blog posts. He expresses a libertarian view. He also writes about climate adaptation. He makes an important point that civilization is not static and we will be able to adapt the human ecology to a range of climate change. But his latest post on how climate change might affect marathon performances raised an important issue for me.
Kahn fails to acknowledge that adaptation to small, incremental climate change is not the concern. It’s the large, catastrophic changes with unknown (and unknowable) probability–deep uncertainty–that is of concern–collapsing ice sheets or ecosystems. He is not addressing the problem of what happens if the climate passes a tipping point. These types of articles and blog posts produced by Kahn and his colleagues trivialize the real risks and consequences, as though we’re just trying to adapt to a change in the weather while ignoring the potential systemic changes.
The Vogtle nuclear power plant cost is projected to balloon to more than $12,000 per megawatt. In a study we did for the California Energy Commission in 2009, even at $4,000 per megawatt, nuclear power was uneconomic. This explains why nuclear power is not taken seriously as a solution to reducing greenhouse gas emissions.

I follow Matthew Kahn, now at USC, post on June 30 about the how the “Lucas Critique” undermines a recent study forecasting how counties across the U.S. might be affected differentially by climate change. Quoting the New Palgrave Economic Dictionary, “The ‘Lucas critique’ is a criticism of econometric policy evaluation procedures that fail to recognize that optimal decision rules of economic agents vary systematically with changes in policy.” In other words, individuals within the economy are able to anticipate changing events, including government decisions, and can mitigate the impacts of those events when compared to continuing with the status quo. Kahn puts great faith in the Chicago School premise that individuals can readily adapt to all conditions without government or collective decisions.
However, Kahn ignores two important points. First, he misses the distributional focus of the study, and instead focuses on the overall efficiency gains from the net changes. That’s not the point of the study. We can see on example that land can’t be moved from one county to another, so landowners can’t adapt in anticipation of climate change without significant investment to protect their land. Homeowners will lose value in their homes, and others will find their asset value stranded. Sure, the overall economy will adapt and certain counties may gain enough to offset those losses, but residents within the net loss counties will be worse off. Economics for too long has focused solely on net gains without parsing the impacts and considering how to manage better outcomes for the losers. (I see this failure as one aspect of dissatisfaction driving Trump voters–which brings me to my second point.)
And second, if the Lucas Critique was truly valid, coal miners in Appalachia would have long abandoned their towns as they saw the decline of coal, and the need to satisfy West Virginia coal miners would not be driving national policy today. Instead, we see that people are myopic and these changes are likely to have significant consequences.
The California State Supreme Court refused to rehear a state appellate court decision that upheld the validity of the cap and trade program (CATP) established in Assembly Bill 32 (2006). Those challenging the program claimed that (1) the program required firms to acquire allowances to operate and (2) that the auction receipts were budgeted into state programs like other tax revenues. However, the Court’s decision was a victory for those who believe that stronger property rights can lead to an improved environment.
The AB 32 CATP defined the property rights for individual firms and for the public in allowed GHG emissions into the atmosphere. CARB also allocated allowances for free to these firms and set rates of declining annual emission totals (with some upward adjustments to accommodate interstate and international competitiveness). This is akin to delineating the acreage that a property owner has, and then setting out a rate at which the property owner must dedicate a portion to public use, while still allowing the owner to continue to use that land. The U.S. Supreme Court just upheld the ability of state governments to regulate land use in this manner. The CATP essentially allows an owner to continue to use the land in same manner by acquiring usage rates from other owners who may find it more lucrative to sell their allowances rather than use them. Under AB 32, the state auctions some of those allowances to make for a liquid market, while other allowances are traded bilaterally amongst firms. The bottom line is that CATP established property rights in GHG emissions, just as California established water property rights in 1914.
If the CATP had been declared to be another tax, then any disbursement of government property that generated revenues, e.g., sale of excess office space or forest land, could also be considered a “tax” subject to a two-thirds vote approval by the State Legislature under the state constitution. I doubt that the plaintiffs in this case (led by the Chamber of Commerce) intended that sale of state property would require a two-thirds supermajority vote.
California’s SB 775 would prohibit interaction with other states’ cap and trade programs. The best alternative to a federal program is a network of state markets.
“A cap-and-trade program in Virginia would be the third in the U.S., and buck direction from the White House to pull back on carbon regulation.”

I’ve been struck by the lack of panic in the energy industry about President Trump’s decision. This article goes into that underlying confidence that the momentum appears unstoppable.
WASHINGTON — President Trump’s decision to abandon the Paris Accord will slow the battle against climate change in the U.S., but there’s too much momentum in the nation’s clean-energy economy to shut it down, energy experts say.
