This study applies recurrent event analysis to examine the determinants of changes in firm credit ratings. This study uses two extended Cox proportional hazard models to examine upgrade and downgrade data separately. Explanatory variables are taken from financial ratios in Z-score (Altman, 1968)...

Post-issue stock underperformance is driven, at least in part, by young issuers with contemporary decline in idiosyncratic risk (proxied by expected idiosyncratic volatility) exposure. We show that the SEO long-run underperformance primarily occurs in young issuers. The intuition is that young...

This article investigates the determinants of large changes in stock prices. Empirical evidences suggest that the asymmetry phenomenon in determinants of large changes in stock prices is found in three stock exchanges. In the New York Stock Exchange (NYSE), momentum effect accounts for most of...

Industry returns cannot be explained fully by well-known asset pricing models. This study reveals that common factors extracted from industry returns carry significant risk premiums that go beyond the explanatory power of size, book-to-market (BM) ratios, and momentum. In particular, this study...

In this paper the authors investigate the performance of the original and repeated Richardson extrapolation methods for American option pricing by implementing both the original and modified Geske–Johnson approximation formulae. A comprehensive numerical comparison includes alternative...

This paper studies the hedging performance of static replication approach proposed by Derman, Ergener, and Kani (DEK, 1995) for continuous barrier options under the constant elasticity of variance (CEV) model of Cox (1975) and Cox and Ross (1976), and then focuses on how to improve the DEK...

This paper extends the static hedging portfolio (SHP) approach of Derman et al. (1995) and Carr et al. (1998) to price and hedge American knock-in put options under the Black–Scholes model and the constant elasticity of variance (CEV) model. We use standard European calls (puts) to construct...

We examine the impact of derivatives hedging on the spot market using accurate hedge ratios of covered warrants traded in the Taiwan Stock Exchange (TWSE). Results present significant positive abnormal returns and trading volumes before the announcement of a warrant’s issuance, and the effect...

This article examines the relationship between political and business connections (PBCs) and firms' financial constraints. We proxy a firm's PBCs by whether or not the firm's CEO should hold a directorship in major trade organizations. Using an endogenous switching regression model, we find that...

This paper investigates whether political connections improve the access of firms to financing. We propose three hypotheses to prove that political benefits exist. First, do politically connected firms obtain preferential treatment for bank loans? Second, if these firms do obtain preferential...
