Global climate cooperation has collapsed but the need for action has not disappeared. This column argues that only radical technological progress can reconcile climate-change goals with development. It argues that four changes in WTO trade rules could facilitate climate-change action and technological advances without unduly damaging trade.
Energy-subsidy reform is notoriously difficult. This column argues that the environmental and social payoff from a concerted worldwide effort to replace these subsidies with better targeted measures would be substantial. Subsidy reform is an especially attractive option for countries under pressure to bring public debt to more prudent levels. The success of reform in several countries shows that the challenge is not insurmountable.
The sordid history of Congressional acceptance and rejection of cap-and-trade: Implications for climate policy
Not so long ago, cap-and-trade mechanisms for environmental protection were popular in Congress. Now, such mechanisms are denigrated. What happened? This column tells the sordid tale of how conservatives in Congress who once supported cap and trade now lambast climate change legislation as ‘cap-and-tax’. Ironically, conservatives are choosing to demonise their own market-based creation. The successful conservative campaign that disparaged cap-and-trade means it may now be politically impossible to promote it in the US. The good news? Elsewhere, cap and trade is now a proven, viable option for tackling large-scale environmental problems.
Commodity price shocks are frequently considered among the most important potential threats to the global economy. However, since the second half of the 1980s, energy prices have experienced very large changes, with arguably limited effects on global GDP developments. This column presents evidence that oil shocks just aren’t what they used to be when it comes to macroeconomic effects.
In the last decade, there has been an explosion in the variety of instruments that permit speculation in oil, such as futures, options, index funds, and exchange-traded funds. This has been called the financialisation of the oil markets. This column examines whether this has affected the oil price and predicts powerful natural limits on the ability of financialisation shifts to raise spot prices in frictionless markets.
