Puzzles of excited charm meson masses

We attempt a comprehensive analysis of the low lying charm meson states which present several puzzles, including the poor determination of masses of several non-strange excited mesons. We use the well-determined masses of the ground states and the strange first excited states to 'predict' the mass of the non-strange first excited state in the framework of heavy hadron chiral perturbation theory, an approach that is complementary to the well-known analysis of Mehen and Springer. This approach points to values for the masses of these states that are smaller than the experimental determinations. We provide a critical assessment of these mass measurements and point out the need for new experimental information. (c) 2007 Elsevier B.V. All rights reserved.

Solving exchange rate puzzles with neither sticky prices nor trade costs

We present a simple framework in which both the exchange rate disconnect and forward bias puzzles are simultaneously resolved. The flexible-price two-country monetary model is extended to include a consumption externality with habit persistence. Habitpersistence is modeled using Campbell Cochrane preferences with ‘deep’ habits along the lines of the work of Ravn, Schmitt-Grohe and Uribe. By deep habits, we mean habits defined over goods rather than countries. The model is simulated using the artificial economy methodology. It offers a neo-classical explanation of the Meese–Rogoff puzzle and mimics the failure of fundamentals to explain nominal exchange rates in a linear setting. Finally, the model naturally generates the negative slope in the standard forward market regression.

Crime, Punishment and Article 3 ECHR: Puzzles and Prospects of Applying an Absolute Right in a Penal Context

Article 3 of the European Convention on Human Rights (ECHR), which provides that ‘No one shall be subjected to torture or to inhuman or degrading treatment or punishment’, is considered to enshrine an absolute right. Yet it contains an under-explored element: inhuman and degrading punishment. While torture has been the subject of extensive academic commentary, and inhuman and degrading treatment has been examined to some extent, the prohibition of inhuman and degrading punishment has not been explored in significant depth, in spite of its considerable potential to alter the penal landscape.

This paper elucidates the key doctrinal elements of inhuman and degrading punishment ‘and treatment associated with it’, in the words of the European Court of Human Rights (ECtHR). It addresses a number of ‘puzzles’ or problems which arise in applying the absolute right enshrined in Article 3 of the ECHR to sentencing and imprisonment, clarifies ECtHR doctrine and highlights some of its key implications. Bringing a theoretically informed understanding to bear on the application of Article 3 of the ECHR in a penal context, the paper provides clarity and coherence to a complex and crucial intersection between human rights and penology.
