SPIRe Working Papers Series
Please Note:
Papers in this working paper series are pre-publication versions of academic articles or book chapters in various stages of completion. Posting a paper on this site does not preclude simultaneous or subsequent publication elsewhere, including other Working Papers series. The copyright of a Working Paper is held by the author(s). Once a paper has been published elsewhere, it is preferable to cite it in its final, published version, rather than in its Working Paper version.
Papers may be downloaded from this site by individuals, for their own use, subject to the ordinary rules governing fair use of professional scholarship. Comments on papers or questions about their content should be sent directly to the author, at his or her email address.
