An experienced user of the Twiddler, a one--handed chording keyboard, averages speeds of 60 words per minute with letter--by--letter typing of standard test phrases. This fast typing rate coupled with the Twiddler's 3x4 button design, similar to that of a standard mobile telephone, makes it a potential alternative to multi--tap for text entry on mobile(More)

Uncertainty in applied macroeconomic policy analysis arises from three distinct sources. The first, often referred to as model uncertainty, arises because the models used for policy analysis are simple abstractions of the complex behavioural interactions that occur in an economy. The second source, denoted shock uncertainty, arises from unforeseen events(More)
Simple rules for guiding monetary policy actions have been shown to achieve policy objectives effectively. In many of these simple rules, policy prescriptions depend on the economy’s level of potential output. Potential output is unobservable, however, and is estimated with uncertainty. We examine the effects that this uncertainty has on the stabilization(More)
In this paper, stochastic simulations of the Reserve Bank of New Zealand's new macroeconomic model, FPS, are used to examine the issue of which price index should monetary policy stabilise in a small open economy. Under the class of policy rules considered, targeting a measure of domestic inflation, which does not include the direct effects of exchange rate(More)
1. HIGHLIGHTS Van den Bergh completed his monograph, The Galaxies of the Local Group, which is being published by Cambridge University Press in 2000. A systematic search begun for faint emission lines indicative of recent star formation in all the bright galaxies in the low-density regions of the Updated Zwicky Catalogue detected 17 new minor-merger pairs.(More)

This paper presents three satellite models for the Forecasting and Policy System (FPS). Satellite models are used to disaggregate the projections generated by the core model into a more detailed profile. The household expenditure, exports, and business investment satellite models dis-aggregate the relevant macroeconomic variables by modelling the shares of(More)
