Pricing Continuously Resettled Contingent Claims
No full textThis paper is a study of continuously resettled contingent claims prices in a stochastic economy. As special cases, the relationship between futures and forward prices is analyzed, and a preference-free expression is derived for these prices, as well as the price of a continuously resettled futures option, whose formula differs from Black's futures option pricing formula due to the effects of marking-to-market the changes in the futures option premium. 1 The first author is pleased to acknowledge the research support of Batterymarch Financial Management. 2 The second author gratefully acknowledges financial support under Overseas Studentship no. 86610291 from the Science and Engineering Research Council. 1 Introduction This paper derives prices of continuously resettled contingent claims in a Markov diffusion setting, This extends the work of Cox, Ingersoll, and Ross (CIR) [4] by pricing a class of assets from which the futures contract and modern futures option are special cases..
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Information Percolation in OTC Markets
No full textThis chapter describes a simple model of the “percolation” of information of common interest through an over-the-counter market with many agents. It also includes an explicit solution for the cross-sectional distribution of posterior beliefs at each time. It begins with the basic information structure for the economy and the setting for search and random matching. It then shows how to solve the model for the dynamics of the cross-sectional distribution of information. The remainder of the chapter is devoted to market settings and to extensions of the model that handle public releases of information, the receipt of new private information over time, and the release of information among groups of more than two agents at a time.</p
