Credit Availability and Farm Land Booms and Busts

This according to a paper just published in the American Economic Review by  Raghuram Rajan and Rodney Ramcharan about bank failures and farm land values in the 1920s:

“How important is the role of credit availability in inflating asset prices? Our evidence suggests it matters. Of course, the influence of credit availability on the asset price boom need not have implied it would exacerbate the bust. Continued easy availability of credit in an area could in fact have cushioned the bust. However, our evidence suggests that the rise in asset prices and the build-up in associated leverage were so substantial that bank failures (resulting from farm loan losses) were significantly more in areas with greater ex ante credit availability. Moreover, the areas that had greater credit availability during the commodity price boom had depressed land
prices and lower credit availability many decades after the bust, probably because farm loan losses resulted in the failure of banks that lent to farmers, and altered banking market structure in subsequent decades.”

“This commentary argues that lack of knowledge in both the scientific community and popular press regarding possible solutions carries over to public health advocates engaged in proposing government policies attempting to lower population weight. Market-based solutions are argued to be imperfect, but continued experimentation and scrutiny from paying customers interested in weight loss ensures progress toward developing effective solutions.”

Economists weight in on sugar tax

Tamar Haspel has another sensible article in the Washington Post, this time on the potential effects of a soda tax.

She interviewed a slew of top food and agricultural economists, and by and large, I agree with most of what they had to say.  There were three points I would have added.

First, Haspel discusses the potential of sugar (rather than soda) taxes without mentioning the fact that sugar is ALREADY taxed (indirectly via various government programs).  Here's what I wrote in a short piece for the Congressional Quarterly on the issue:

“Should the government tax sugared soda? It already does. Farm policies make U.S. sugar prices two to three times higher than elsewhere. Moreover, ethanol policies have led to a more than doubling of the price of high fructose corn syrup since 2005. It’s no wonder that per capita sugar consumption has fallen precipitously over the last decade.”

Second, while Haspel mentions a quote from the industry that the taxes are "unfair", she doesn't mention that they're regressive -meaning  the costs being born relatively more by those who can least afford to pay them.  Yes, we need to raise government revenue some way, but as I've noted before, even some good economists seem to miss the fact that we should choose taxes in a way to minimize dead weight loss, not how taxes feel or appeal to a particular cause.

Finally, despite acknowledging that soda taxes are likely to have very little benefits, Haspel concludes,

“If the choice is to do this or do nothing, I choose this. ”

I'm sorry, but if my choice is between nothing and a policy that is paternalistic, regressive, will create economic distortions and deadweight loss, and is unlikely to have any significant effects on public health, I choose nothing.
