In this paper we present discretization and decomposition methods for a multi-component transport model of a chemical vapor deposition (CVD) process. CVD processes are used to manufacture deposition layers or bulk materials. In our transport model we simulate the deposition of thin layers. The microscopic model is based on the heavy particles, which are derived by approximately solving a linear...

using the treynor and mazoy model (expanded by fama to evaluate management performance for asset allocation among investment units), this paper examines the management’s performance in funds and investment companies in tehran stock exchange during 2004-2010. the results do not support the application of management market timing during the study period and managers were only able to create addit...

Jegadeesh and Titman (1993) document individual stock momentum: strategies that buy stocks that have performed relatively well in the past and sell stocks that have performed relatively poorly in the past generate significant positive returns over the 3to 12-month horizon. This finding, obtained using data from the U.S. market, also holds for a number of international markets [e.g., Haugen and ...

The Fama-MacBeth [1] cross-sectional regression technique is a mainstay of empirical finance. Yet researchers and practitioners are forced to reinvent the wheel when implementing this method because the original data and code are not available. Some might think, “Fama and MacBeth’s description of what they did is clear enough and it’s easy to program this method.” Yet, anyone who possesses even...

A multivariate normal mean-variance heterogeneous tails mixture distribution is proposed for the joint of financial factors and asset returns (referred to as Factor-HGH). The latent variable model incorporates a Cholesky decomposition dispersion matrix ensure rich dependency structure capturing stylized facts data. It generalizes several existing structures, with or without factors. further app...

a r t i c l e i n f o I propose a new multi-factor asset pricing model with new-Keynesian factors to explain stock return anomalies from 1972Q1 to 2009Q2. This new model explains the average returns across testing portfolios formed on financial distress, momentum, and standardized unexpected earnings with misspecification-robust statistics. Test portfolios formed on net stock issues and total a...

This paper examines the validity of the Sharpe-Linter-Black Capital Asset Pricing Model (CAPM) to stocks traded on the Barbados, Jamaica and Trinidad & Tobago Stock Exchanges. Tests of the CAPM are based on portfolio betas made up of stocks emanating from all three exchanges and are carried out on the alternative multifactor specification proposed by Fama and French (1992), extended to include ...
