It is a common and poor framing of the question to ask whether uncertainty is causing our current economic woes. Just as the path of GDP is more volatile and difficult to forecast than in stable growth years, the path of individual firm sales is similarly more volatile and uncertain. More uncertainty will make households and businesses save more and invest and spend less. There is nothing controversial here. The debate is about the cause of uncertainty, and here I see a troubling correlation between what people think the current villain is and what their non-recession bugaboos are. The narratives struggling to tie the current economic woes to long-run stagnating wages, an undereducated workforce, and anything Democrats do strike me as a tenuous stretch and reflect our tendency to need a compelling narrative when easy explanations do not present themselves.
I think a good test for yourself is to ask “what problems do you think are important today that you didn’t think were important in 2004, and what policies would you favor now that you would have opposed then?”. My answer is that low house prices are a problem today where I would previously said low prices are just transfers from sellers to buyers, and I would favor policies that prop them up when I would previously have opposed them. What are yours?
