Banknotes and demand deposits have exhibited high growth since the late 1990s, and remain at historically high levels. We examine the background to these developments by using available data such as the volume of banknotes in circulation by denomination and the volume of demand deposits by...

The paper studies equilibria for economies with imperfect competition and non-convex technologies. Following Negishi, firms maximise profits under downward-sloping perceived demand functions. Negishi's assumptions, in particular the assumption of a single monopolistic competitor in each market,...

We study the term structure of interest rates and monetary policy in Japan empirically, using a macro-finance model. In particular, we investigate whether or not Japan's low long-term interest rates can be explained with economic rationality by taking into account some key features of the...
