A comparison of optimal policy rules prior to and during inflation targeting: empirical evidence from Bank of Canada

We examine policy rules that are consistent with inflation targeting (IT) framework in a small macroeconomic model of the Canadian economy. We set up an optimal linear regulator problem and derive policy rules to compare the dynamics of pre-IT and IT eras. We find that while the optimal monetary policy rule in the pre-IT period is best described with a loss function that attaches equal weight to price stability, financial stability and output stability; the IT era is dominated by the price stability objective followed by the financial stability and output stability, consecutively. Moreover, we do not find an explicit role for exchange rate stability in the objective function of the Bank of Canada for both monetary policy eras. We, then, compare the properties of the derived optimal rules with those of an ad hoc Taylor rule for the IT period. In response to inflationary shocks, Taylor rule brings down inflation rates more quickly compared to the derived policy rules, but at the cost of a higher sacrifice ratio and more volatile interest rates

Life Satisfaction and Keeping Up with Other Countries

Micro income studies show that relative income of individuals-with respect to their colleagues, friends, etc.-affects their life satisfaction significantly. This paper attempts to extend these studies by using the idea that people may compare their well-being not only to well-being of their home country folks but also to well-being of other country citizens. Using data from national surveys of 55 countries, carried out from 1973 to 2011, we find that average life satisfaction of a country is significantly affected from how much that country is deprived of income compared to richer countries in the world. Furthermore, per capita income of a country only matters as far as it affects its relative position in the global income distribution. This result, gaining statistical significance after 1990s, is a potential explanation for the paradox that even though richer countries tend to be happier compared to poor ones, a country does not necessarily get happier as its income increases
