    Genuine savings : leading indicator of sustainable development?
    (University of Chicago Press, 2005-04) ;
    The World Bank recently began publishing estimates of countries' “genuine savings”: a comprehensive measure of net investment across all forms of capital (natural and human as well as produced). This article presents the first empirical investigation of the consistency of the Bank's estimates with the hypothesis that net investment should equal the difference between a country's average future consumption and its current consumption. Results show that the Bank's estimates are consistent only with weak versions of this hypothesis and then only for developing countries. Moreover, a simple autoregressive-integrated-moving-average (ARIMA) model outperforms any net investment measure, comprehensive or conventional, as a predictor of the difference between current and future consumption. In sum, the Bank's net investment estimates tend to move in the same direction as the difference between current and average future consumption in developing countries, but they have little value for predicting the magnitude of this difference.

    Impact of bus priority attributes on catchment area residents in Dublin, Ireland
    (Center of Urban Transport Research, 2006) ; ;
    In many jurisdictions, political and infrastructural restrictions have limited the feasibility of road pricing as a response to urban congestion. Accordingly, the allocation of dedicated road space to high frequency buses has emerged as a second-best option. Analyses of the evidence emerging from this option emphasize the engineering and technical issues and do not systematically interrogate the customers, those in the bus catchment area that use or could potentially use the service. This paper attempts to correct for this asymmetry in focus by analyzing characteristics and preferences of users and non-users through a survey of 1,000 households for a particular quality bus catchment area in Dublin, Ireland. Preliminary findings are encouraging, both for the use of this policy instrument as one which can yield considerable consumer satisfaction, and in terms of modal share analysis, especially because the corridor under scrutiny represents a much higher socio-economic profile than Dublin or Ireland as a whole.
