Three π-A-porphyrins containing long alkoxyl chains attached to the ortho position of phenyl ring and a phenyl carboxylate acid or acrylic acid at the meso position of porphyrin were synthesized. All compounds were characterized by 1H NMR and mass spectrometry. Optical and electrochemical...

This paper compares the changes in implied volatilities of options on Nasdaq 100 and Russell 2000 value and growth portfolios. Following Stein (1989) and Heynen, Kemna, and Vorst's (1994), we assume mean reversion, GARCH and EGARCH models for volatility. The empirical evidence using put options...

Chapter 1 of the dissertation investigates the firms’ restructuring choice betweenminority carve-outs and tracking stocks using samples during 1990-2001. The extracompensation from the restructured units, the liquidity conditions, and the preservation ofsynergy are the significant factors...

In this paper, we examine factors influencing the choice between tracking stocks and minority carve-outs and their performances. We expand the research in this field by incorporating a fa ctor that was largely ignored in extant literature: managerial entrenchment. We find that the following...

The existence of stationary Markov perfect equilibria in stochastic games is shown in several contexts under a general condition called "coarser transition kernels". These results include various earlier existence results on correlated equilibria, noisy stochastic games, stochastic games with...

This paper aims to solve two fundamental problems on finite or infinite horizon dynamic games with perfect or almost perfect information. Under some mild conditions, we prove (1) the existence of subgame-perfect equilibria in general dynamic games with almost perfect information, and (2) the...
