In this paper, the main sources of nonlinear distortions for back-to-back (B2B) transmission in an Intensity Modulation/Direct Detection (IM/DD) fiber optical system are presented. The nonlinear characteristics are modelled and their impact on an OFDM signal are described by means of stochastic considerations. Furthermore, the dependence of nonlinear distortions on tunable key parameters of the...

Capital Asset Pricing Model (CAPM) provides an equilibrium linear relationship between expected return and risk of an asset. The purpose of this paper is to investigate a risk-return relationship within the CAPM framework. The study also aims at exploring whether CAPM is a good indicator of asset pricing in Bangladesh. For this study, a period 19992003 have been considered. Fama-French [1992] m...

This paper proposes an investment-based explanation and resolves the post-merger performance puzzle. Traditional asset pricing models fail to take into account the link between investment and performance, and hence, resulting in post-merger performance puzzle. Upon observing that disproportionately high fraction of acquirers are high Tobin’s Q firms, a group characterized with high investment r...

We derive new bounds and distance measures for stochastic discount factors (SDFs) that generalize the original variance bounds and distance of Hansen and Jagannathan (1991, 1997) and higher moment bounds of Snow (1991). These generalized measures are suitable to analyze nonlinearities in asset pricing models and trading strategies. They imply nonlinear admissible SDFs that provide a more robust...

This paper presents modeling and simulation on the characteristics of semiconductor laser modulated within a strong optical feedback (OFB-)induced photon-photon resonance over a passband of millimeter (mm) frequencies. Continuous wave (CW) operation of the laser under strong OFB is required to achieve the photon-photon resonance in the mm-wave band. The simulated time-domain characteristics of ...
