The administered Bank rate and the Canada-U.S. spot exchange rate: 1975–1979

This paper analyzes, for the period 1975–1979, the announcement effect of the unanticipated Canadian administered Bank rate changes (the Bank rate is analogous to the discount rate in the U.S.) on the Canada-U.S. dollar spot exchange rate. Leading and/or lagged announcement effects are also investigated. By examining the behaviour of the residuals, on and surrounding the announced Bank rate changes, derived from an autoregressive equation of the daily changes (4:30 p.m. to noon the following day) in the logarithm of the spot $ Canadian/$ U.S. rate the evidence seems to indicate, on the average, a significant adjustment (appreciation of the Canadian dollar for Bank rate increases and depreciation for Bank rate decreases) of the exchange rate on the day of the effective unanticipated administered Bank rate changes regardless of the assumptions made with respect to the probability distribution of the residuals — whether it be normal, symmetric stable with a characteristic exponent of 1.8, or nonparametric.     

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.

2 Discourse Ethics, Democracy, and International Law: Toward a Globalization of Practical Reason

A bstract .   This paper deals with the foundational "architectonics" (Kantian) at the ground of the internal relation between the three concepts raised in the title. First, I provide a short introduction into the ultimate foundation of practical philosophy by the transcendental-pragmatic conception of discourse ethics . Then, I discuss the foundational relation between discourse ethics , positive law , and democracy as a constitutional state of law . Finally, I explore the foundational relation between human rights as part of universal law, the democratic state of law, and international law or jus gentium . By taking issue with Kant, Habermas, and Rawls, I try to show that a rational foundation of ethics, as well as a rational approach to the traditional problems of international law, is only possible through a critical transformation of Kant's approach via a transcendental-pragmatic conception of discourse ethics.     

System estimates of potential output and the NAIRU

This paper proposes a new approach for estimating potential output and the NAIRU. The methodology models these key unobservable economic variables as latent stochastic trends within a trivariate system of observables comprising information on unemployment, GDP, and inflation. Identification is achieved through the use of a standard version of Okun's law and a Phillips curve. The performance of the procedure is investigated using Swedish quarterly data covering the time period 1970:1–1996:3. First version received: June 1997/final version received: September 1998
