This book examines whether continuous-time models in frictionless financial economies can be well approximated by discrete-time models. It specifically looks to answer the question: in what sense and to what extent does the famous Black-Scholes-Merton (BSM) continuous-time model of financial markets idealize more realistic discrete-time models of those markets? While it is well known that the BSM model is an idealization of discrete-time economies where the stock price process is driven by a binomial random walk, it is less known that the BSM model idealizes discrete-time economies whose stock price process is driven by more general random walks. Starting with the basic foundations of discrete-time and continuous-time models, David M. Kreps takes the reader through to this important insight with the goal of lowering the entry barrier for many mainstream financial economists, thus bringing less-technical readers to a better understanding of the connections between BSM and nearby discret

This introduction to some of the principal models in the theory of disordered systems leads the reader through the basics, to the very edge of contemporary research, with the minimum of technical fuss. Topics covered include random walk, percolation, self-avoiding walk, interacting particle systems, uniform spanning tree, random graphs, as well as the Ising, Potts, and random-cluster models for ferromagnetism, and the Lorentz model for motion in a random medium. This new edition features accounts of major recent progress, including the exact value of the connective constant of the hexagonal lattice, and the critical point of the random-cluster model on the square lattice. The choice of topics is strongly motivated by modern applications, and focuses on areas that merit further research. Accessible to a wide audience of mathematicians and physicists, this book can be used as a graduate course text. Each chapter ends with a range of exercises.

How do middle-class Americans become aware of distant social problems and act against them? US colleges, congregations, and seminaries increasingly promote immersion travel as a way to bridge global distance, produce empathy, and increase global awareness. But does it? Drawing from a mixed methods study of a progressive, religious immersion travel organization at the US-Mexico border, Empathy Beyond US Borders provides a broad sociological context for the rise of immersion travel as a form of transnational civic engagement. Gary J. Adler, Jr follows alongside immersion travelers as they meet undocumented immigrants, walk desert trails, and witness deportations. His close observations combine with interviews and surveys to evaluate the potential of this civic action, while developing theory about culture, empathy, and progressive religion in transnational civic life. This timely book describes the moralization of travel, the organizational challenges of transnational engagement, and the
