Social scientists are reluctant to make explicit interpersonal comparisons of well-being. However, implicit comparisons are made on a surprisingly regular basis. These comparisons are based on the wealth and the Kaldor–Hicks concept in utility theory and on self-reported well-being in happiness research. Taking a utilitarian stance, this paper tests the ethical foundations of both principles. While self-reported well-being serves as an acceptable proxy for utilitarian decision-making, the Kaldor–Hicks concept does not appear so. Implications for evaluating policies are outlined.

The economic effects of federalism are unclear: some papers find that federalism has strong positive effects on a number of economically relevant variables, others find negative effects. The results often crucially hinge on the proxies for federalism used. In this paper, we critically survey the existing indicators for both federalism and fiscal decentralization. We argue that federalism is a constitutional institution, whereas decentralization is the outcome of a policy choice, and that the two ought to be systematically distinguished because decentralization can also occur in nonfederally structured states. We further argue that institutional details are very important with regard to federalism and that dummy variables usually capture only very specific aspects of these institutional details. We use factor analysis to test whether the latent variables behind the observed indicators support these assumptions. More than two important factors are derived, implying that a more fine-grained differentiation beyond simply “‘federalism” and “decentralization” might be in order. The correlations of the most important proxies for various aspects of federalism and decentralization with a number of quasi-exogenous variables, as well as with institutional variables, are usually rather modest.  相似文献

I estimate a reaction function for the ECB using an ordered logit model for the period 1999-2009. Allowing for a smooth transition from one set of parameters to another, I detect a rapid change in the middle of 2008.  相似文献

In this paper we propose a 4-index formulation for the uncapacitated multiple allocation hub location problem tailored for urban transport and liner shipping network design. This formulation is very tight and most of the tractable instances for MIP solvers are optimally solvable at the root node. While the existing state-of-the-art MIP solvers fail to solve even small size instances of problem, our accelerated and efficient primal (Benders) decomposition solves larger ones. In addition, a very efficient greedy heuristic, proven to be capable of obtaining high quality solutions, is proposed. We also introduce fixed cost values for Australian Post (AP) dataset.  相似文献

Over 90 percent of companies are estimated to use IT Service Management (ITSM) frameworks, yet there is little research on their benefits to the Information Technology (IT) department and the business units. An international survey of 491 firms was conducted to assess the benefits of the IT Infrastructure Library (ITIL), the de-facto ITSM framework, specifically on how these benefits evolve as companies increase their adoption of the ITIL model. Also studied are the perception of challenges of the implementation and the number of ITIL processes implemented in relation to the progress of the adoption of ITIL. Results indicate that as the maturity of implementation increases, the perception of challenges decreases. Findings also show that as the maturity of implementation increases, the number of realized benefits increases, as well as the number of implemented ITIL processes. Implications for practitioners and researchers are also discussed.  相似文献
