We show how time-series of random market trade values and volumes completely describe stochasticity of stock returns. We derive equation that links up returns with current and past trade values and show how statistical moments of the trade values and volumes determine statistical moments of...

The paper develops an easy-to-apply test for contagion. In order to address the main challenge of any contagion test, that of endogeneity, the testing is conducted in the structural vector autoregression (SVAR) framework where we assume the reduced form errors follow a mixed-normal distribution....

We present evidence of significant bias in event studies that investigate the effect of U.S. monetary policy on U.S. stock prices. To overcome this bias, we propose a new identification method based on the "Impossible Trinity" theory which argues that an economy with a fixed exchange rate and...

Expected returns and risk assessment are important issues when evaluating capital investment projects. We use VARX-MGARCH models and asset pricing theory to model the expected rate of return in Brazil, Colombia, Mexico and Peru for late 2006. The main objective of this paper is to present an...

This research investigates Banks' profitability in the United Arab Emirates from 2008 to 2012 using Bankscope Data Base, Financial Statement, and quantitative methodology techniques. This study focuses on 4 banks, 2 Islamic banks (Dubai Islamic Bank PJSC, Abu Dhabi Islamic Bank - Public Joint...

This paper looks at the history of money and its modern form from a scientific and mathematical point of view. The approach here is to emphasize simplicity. A straightforward model and algebraic formula for a large economy analogous to the ideal gas law of thermodynamics is proposed. It may be...

The financial performance of governments in issuing debt is an open empirical question. We develop performance measures for the decisions debt management offices (DMOs) face: The amount to issue is largely exogenous to them, but they determine its distribution across issue dates (timing) and the...

We study arbitrage opportunities in diverse markets as introduced by R. Fernholz in [Fer99]. By a change of measure technique we are able to generate a variety of diverse markets. The construction is based on an absolutely continuous, but nonequivalent measure change which implies the existence...

This paper studies a dynamic market microstructure model, in which a strategic market maker competes with an informed trader. We include the presence of noise traders and limit order traders in our setup. Our model is a N-period model. We give necessary and sufficient conditions for an...

We present an order flow model framework for limit order driven markets. Different from previous models we explicitly model a reference price process that “sweeps” the limit order book as it fluctuates up and down. Our framework allows us to use any stochastic process to model this reference...
