Essays on coordination and financial markets
No full textThis dissertation is concerned with microeconomic models of equilibrium pricing in financial markets of varying organizational scope. The first two chapters are based on game-theoretic models characterized by a coordination problem. I begin at the industry level in Chapter 2 where I solve the chicken-or-the-egg problem of platform pricing. I show that the elasticity of demand is greater for the more valued side and hence a monopolist will charge that side a lower price. These results have implications on how exchanges admit traders and apply to more general two-sided markets. My findings are supported by experimental tests. Chapter 3 examines regulatory efficacy in manipulating a currency market with a peg. I solve for equilibrium speculator conduct and central bank intervention policy where the speculator population is discrete. Sudden equilibrium price collapses are related explicitly to fundamentals. The main findings are again supported by experimental tests. In the final chapter, I study a market where strategic behavior is set aside and market participants are instead assumed to be perfect delta hedgers who immediately exploit arbitrage opportunities. I numerically estimate the equilibrium price of an exotic option in such a market.Ph. D.Includes bibliographical referencesIncludes vitaby Nicholas B. Galuni
Personal BioBlitz: A New Way to Encourage Biodiversity Discovery and Knowledge in K-99 Education and Outreach
No full textBroad and detailed knowledge about common species in everyday life has decreased among the public. Even biology researchers may be largely unaware of our everyday biodiversity. To counter such 'species blindness' and create long-term excitement and learning about the biodiversity we see every day, we arranged 76-day BioBlitzes at Rutgers University (New Jersey, USA) in 2014 and 2015 where participants identified and listed all species they discovered. The result was 7270/11748 observations from 30/78 participants and 7/13 countries, including 3458/3057 unique taxa, 91%/99.9% identified to species and 80%/54% listed only by one person (2014/2015). Observations of organismal groups did not strongly correspond to number of estimated species worldwide, but appeared to be related to perceived charisma, body size, and organism mobility. Participants reported increased ability to 'see' species and to identify new groups, learning new tools of species identification and strongly increasing their biodiversity knowledge and eagerness to learn more.Peer reviewe
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
