Is Japan’s aging and, more recently, declining population hampering its growth and reflation efforts? Exploiting the demographic and economic variation in the prefectural data between 1990 and 2007, we find that aging of the working age population has had a significant negative impact on the total factor productivity (TFP). Moreover, prefectures that aged at a faster pace experienced lower overall inflation, while prefectures with higher population growth experienced higher inflation. The results give strong support to the notion that demographic headwinds can have a non-trivial impact on the TFP and deflationary pressures.
In this paper we examine how target ranges work in the context of a Barro-Gordon (1983) type model, in which the time-inconsistency problem stems from political pressures from the government. We show that target ranges turn out to be an excellent way to cope with the time-inconsistency problem, and achieve many of the benefits that arise under practically less attractive solutions such as the conservative central banker and optimal inflation contracts. Our theoretical model also shows how an inflation targeting range should be set and how it should respond to changes in the nature of shocks to the economy.
In this paper we provide a theoretical treatment of how inflation target ranges cope with the time-inconsistency problem arising from incentives for the monetary policymaker to exploit the short-run trade-off between employment and inflation to pursue short-run employment objectives, as in a Barro-Gordon (1983) model. Inflation band targets are able to achieve many of the benefits that arise under practically less attractive solutions such as the conservative central banker and optimal inflation contracts. Our theoretical model also shows how an inflation targeting range should be set and how it should respond to changes in the nature of shocks to the economy.
