A theory-consistent system approach for estimating potential output and the NAIRU

A new approach is proposed for estimating potential output and the NAIRU. Identification is achieved using Okun’s law and a Phillips curve. The performance of the methodology is exemplified using data from Canada, the UK, and the US.

Personal Taxation and Investment Incentives in a Small Open Economy

A simple portfolio model is used to investigate the effects of personal taxes on real investment incentives in a small open economy with large and small firms. When shares in large firms can be traded internationally and their rate of return is exogenously determined on international equity markets, a tax on the return on riskless bonds will induce a portfolio shift from bonds to shares in large firms. This shift reduces the impact of the bond tax on the required rate of return on shares in domestically owned small firms, provided that returns on shares in small and large firms are positively correlated. The total impact of the bond tax may even change from a negative to a counter-intuitive positive one if the “beta” between the returns on small and large firms is above unity. A personal tax on equity returns does in general have an ambiguous impact on the pre-tax rate of return requirement of domestically owned firms. An exogenous rate of return on large company shares is shown to enhance the possibility for the equity tax to reduce the required pre-tax rate of return in small domestic firms. A sufficient condition for a negative relationship is again that the “beta” between the returns in small and large firms is above unity.

The Information Content of Central Bank Minutes

One characteristic feature of central banks today is that policy decisions are almost exclusively made by a committee rather than by a single policy maker. Another is that central banks are considerably more transparent than they used to be. Together, this has brought to the fore an important but so far unresolved issue: to what extent should a central bank’s communication reflect the full spectrum of opinions among its committee members? Does information on all members’ views make monetary policy easier to understand and predict, or does it make it harder? We address this issue by employing a novel method. We measure the sentiment and tone of the minutes of the Swedish central bank using an automated content analysis that converts the qualitative information in the minutes to a quantitative measure. We find that this measure is useful in predicting future policy rate decisions.

Some Further Evidence on Interest-Rate Smoothing: The Role of Measurement Errors in the Output Gap

It has been suggested that interest-rate smoothing may be partly explained by an omitted variable that relates to conditions in financial markets. We propose an alternative interpretation that suggests that it relates to measurement errors in the output gap.

Monetary Policy Decisions - Comparing Theory and 'Inside' Information from MPC Members

How do monetary policy committee (MPC) members form their views about the appropriate interest rate? To what extent do they change their minds during the deliberations in the interest rate meeting? How important is the Chairman? The theoretical literature makes assumptions about these issues. We have asked actual MPC members in Sweden and Norway. This paper reports the results from this unique survey and discusses how well existing theories on monetary policy by committee capture the reality.
