The latest ONS inflation figures for the UK show a rise from 2.4% to 2.7% (annualised). This rise doesn't surprise most consumers. One thing which my wife (who is not an economist) has pointed out to me is that the marked price of many products is not going up, but the quantity of product being sold has been reduced. For example, Twix bars are getting smaller, there are 8 slices of cheese instead of 10 in many cheese-slice packets, and Shloer bottles have gone from being 1 litre to 750ml. These changes may fool some consumers into thinking that there is no inflation, but in reality there is. What about the price of services or other more complex products? Could firms be reducing quality rather than increasing price? It is hard for CPI measures to pick up a deterioration in quality, which means that inflation can be underestimated.
Daron Acemoglu, Simon Johnson, Amir Kermani, James Kwak and Todd Mitton have written a paper on whether firms connected to Timothy Geithner benefited from these connections. They do so by looking at how stocks of these firms reacted to the announcement that he was a nominee for Treasury Secretary in November 2008. They find that there were large abnormal returns for connected firms. Below is the paper's abstract and the full paper is available here .

This return was about 6% after the first full day of trading and about 12% after ten trading days. There were subsequently abnormal negative returns for connected firms when news broke that Geithner's confirmation might be derailed by tax issues. Excess returns for connected firms may reflect the perceived impact of relying on the advice of a small ne...
