We describe a dynamic model of financial intermediation in which fundamental characteristics of the economy imply a unique equilibrium path of bank and financial market lending. Yet we also show that economies whose fundamental characteristics have converged may continue to have very different financial structures. Because setting up financial markets is costly in our model, economies that emph...

We study a financial market economy with a continuum of borrowers and pooling of borrowers’ promises. Under these conditions and in the absence of designing costs, utility-maximizing decisions of price-taking borrowersmay lead to financial market incompleteness. Parametrizing equilibria through the borrowers’ no-arbitrage beliefs, we link expectations to the financial market structure. Markets ...

there have been several efforts in the literature to extract as much information as possible from the financial networks. most of the research has been concerned about the hierarchical structures, clustering, topology and also the behavior of the market network; but not a notable work on the network filtration exists. this paper proposes a stock market filtering model using the correlation - ba...

The quantitative study of financial markets is more and more widespread due to their growing importance in the economy and everyday life. Financial markets can be viewed as real-world complex dynamical systems which are continually evolving, have significant practical importance and produce an enormous amount of data recording the aggregate action of many participants. In recent years, the quan...

Over the past two decades, financial market crises with similar features have occurred in different regions of the world. Unstable cross-market linkages during a crisis are referred to as financial contagion. We simulate crisis transmission in the context of a model of market participants adopting various strategies; this allows testing for financial contagion under alternative scenarios. Using...

We consider dynamics of financial market as dynamics of expectations and discuss such a dynamics from the point of view of phe-nomenological thermodynamics. We describe financial Carnot cycle and financial analogue of heat machine. We see, that while in physics perpetuum mobile is absolutely impossible, in economics this may happen under some conditions. In econophysics different analogies betw...

The recent crash demonstrated (once again) that the description of the financial market by present financial mathematics cannot be considered as totally satisfactory. We remind that nowadays financial mathematics is heavily based on the use of random variables and stochastic processes which are described by Kolmogorov’s measuretheoretic model for probability (“classical probabilistic model”). I...

recent bankruptcy of big companies all over the world and fluctuations in iran's stock market require that some methods be developed for the evaluation of companies' financial potential. different models are used for the prediction of bankruptcy and the evaluation of organizational financial situation. environmental changes and increasing competition among agencies led to companies&ap...

As one of the most important financial innovations in 1990s, Commercial MortgageBacked Securities (CMBS) have provided significant amounts of financing for commercial real estate. However, when the Asian and Russian financial crisis hit in 1998, the low rated CMBS market almost dried up and one of the dominant investors Criimi Mae went to Chapter 11 for protection. This study investigates the e...
