Left unaddressed during the past 3 years in most of the debates between economists has been the problem of energy. The reason is simple: post-war economists don’t do energy, except as an ever-expanding resource that the credit system and technology makes available. For the post-war economist, the supply curve of energy–save for brief lags–is always coming back into rough equilibrium with the economy.
Only an economist could wonder in their leisure now, whether energy played a significant role in our current crisis. Indeed the public remarks of Ben Bernanke on the matter of energy, during the 2005-2010 period, were at least as clueless as his embarrassing commentary on the historic bubble in housing and credit. As the nation’s chief economist, Bernanke saw no problem with credit, with derivatives, with the fast inflation in housing prices, or with energy prices. And as an American economist, he was not alone.
As state’s see their budgets collapse and start a new round of layoffs, we should consider the fact that house price inflation masked the lack of wage growth in the United States. And now that house prices continue their descent for a 5th year, American workers are more fully exposed to the decade-long march higher in energy costs. They can experience this individually through energy prices, or more generally through the overall energy cost to the economy.
