Default probability is a fundamental variable determining the credit worthiness of a firm and equity volatility estimation plays a key role in its evaluation. Assuming a structural credit risk modeling approach, we study the impact of choosing different non parametric equity volatility estimators on default probability evaluation, when market microstructure noise is considered. A general stocha...

this paper investigates the asymmetry in volatility of returns for the iranian stock market using the daily closing values of the tehran exchange price index (tepix) covering the period from march 25, 2001 to july 25, 2012, with a total of 2743 observations. to this end, two sets of tests have been employed: the first set is based on the residuals derived from a symmetric garch (1,1) model. the...

This paper examines under what circumstances the market-based compensation scheme is effective in inducing managers’ incentives. We combine the optimal contract theory with the market microstructure literature and endogenize both the optimal compensation scheme and the stock market equilibrium. We analytically show that the incentive pay works better in a more efficient (or more informative) st...

This paper suggests that the interactions of security trades and quote revisions be modeled as a vector autoregressive system. Within this framework, a trade's information effect may be meaningfully measured as the ultimate price impact of the trade innovation. Estimates for a sample of NYSE issues suggest: a trade's full price impact arrives only with a protracted lag; the impact is a positive...

This dissertation develops structural models for analyzing shipping investment decisions, namely ordering, scrapping and lay-up decisions in the tanker industry. We develop models, based on a microeconomic specification, that allow us to understand the dynamics of shipping investment decisions under uncertainty and test interrelated economic assertions with aggregate data. The main framework is...

We discuss a series of simple models for the microstructure of a double auction market without intermediaries. We specialize to those markets, such interdealer broker markets, which are dominated by professional traders, who trade mainly through limit orders, watch markets closely, and move their limit order prices frequently. We model these markets as a set of buyers and a set of sellers, whos...

A technique of computing the pressure drop and deposition rate evolution during soot loading and the 3D distribution of deposited soot particles for micro-structured ceramic filter media is presented. Methods developed at Fraunhofer ITWM for generating 3D computer models representing the microstructure of the filter material and for computing soot particle deposition in the microstructure model...

There is a growing body of research on agent-based models of financial markets that explores the relation between behavior of market participants and statistical properties of aggregate markets variables such as prices and trading volume. We first consider some methodological issues related to this approach: comparison with stylized empirical facts, the distinction between generic and non-gener...
