Simple econometric tests reported in the literature consistently report what appears to be a bias in inflation expectations. These results are commonly interpreted as constituting evidence overturning the hypothesis of rational expectations. In this paper, we investigate the validity of such an...

This paper extends the use of Rao (1982b)'s Quadratic Entropy (RQE) to modern portfolio theory. It argues that the RQE of a portfolio is a valid, exible and unifying approach to measuring portfolio diversification. The paper demonstrates that portfolio's RQE can encompass most existing measures,...

negative shocks to technology.

profits in turn reduces the return to innovation, and a link between inflation and the growth rate emerges. We explore this relationship, relate it to the empirical literature on the growth-inflation connection, and quantify its welfare implications. In particular, we show that the costs of...

The long-run relation between growth and inflation has not yet been studied in the context of nominal price and wage rigidities, despite the fact that these rigidities now figure prominently in workhorse macroeconomic models. We therefore integrate staggered price- and wage-setting into an...

We estimate the impact of exchange rate fluctuations and other external factors on hours worked and employment in Canada's manufacturing industries. The analysis is based on a dynamic model of labour demand and the econometric strategy employs a dynamic OLS approach for cointegrating...

What are the steady-state implications of inflation in a general-equilibrium model with real per capita output growth and staggered nominal price and wage contracts? Surprisingly, a benchmark calibration implies an optimal inflation rate of -1.9 percent. The analysis also shows that trend...

Several recent papers report evidence of an apparent statistical bias in inflation expectations and interpret these findings as overturning the rational expectations hypothesis. In this paper, we investigate the validity of such an interpretation. We present a computational dynamic general...

Evidence suggests that banks, like firms, face financial frictions when raising funds. In this paper, we develop a quantitative, monetary business cycle model in which agency problems affect both the relationship between banks and firms as well as that linking banks to their depositors. As a...
