I present and solve the problem of a producer who faces costs of acquiring, absorbing, and processing information. I establish a series of theoretical results describing the producer's behaviour. First, I find the conditions under which the producer prefers to set a plan for the price he or she charges, or instead prefers to set a plan for the quantity he or she sells. Second, I show that the agent rationally chooses to be inattentive to news, only sporadically updating his or her information. I solve for the optimal length of inattentiveness and characterize its determinants. Third, I explicitly aggregate the behaviour of many such producers. I apply these results to a model of inflation. I find that the model can fit the quantitative facts on post-war inflation remarkably well, that it is a good forecaster of future inflation, and that it survives the Lucas critique by fitting also the pre-war facts on inflation moderately well.

This paper assesses the cross country `stylised facts' on empirical measures of the losses incurred during periods of banking crises. We first consider the direct resolution costs to the government and then the broader costs to the welfare of the economy – proxied by losses in GDP. We find that the cumulative output losses incurred during crisis periods are large, roughly 15–20%, on average, of annual GDP. In contrast to previous research, we also find that output losses incurred during crises in developed countries are as high, or higher, on average, than those in emerging-market economies. Moreover, output losses during crisis periods in developed countries also appear to be significantly larger – 10–15% – than in neighbouring countries that did not at the time experience severe banking problems. In emerging-market economies, by contrast, banking crises appear to be costly only when accompanied by a currency crisis. These results seem robust to allowing for macroeconomic conditions at the outset of crisis – in particular low and declining output growth – that have also contributed to future output losses during crises episodes.
