This study derives approximate valuation formulas for basket options and Asian options under the jump‐diffusion process. To obtain an approximation for options prices under the jump‐diffusion process, we extend the Taylor expansion method developed by Ju N. (<link href="#bib18">2002</link>) under the diffusion...

This paper studies a Markov chain model that, unlike the existing models, has a stochastic default rate model so as to reflect real world phenomena. We extend the existing Markov chain models as follows: First, our model includes both the economy‐wide and the rating‐specific factors, which...

The authors suggest a modified quadratic approximation scheme, and apply this scheme to American barrier (knock‐out) and floating‐strike lookback options. This modified scheme introduces an additional parameter into the quadratic approximation method, originally suggested by G....

<section xml:id="fut21618-sec-0001"> This study proposes a new estimation approach for option valuation (an implied pricing kernel‐based approach), which estimates model parameters under the physical probability measure (P‐measure) using a pricing kernel implied by the GARCH option pricing model. Analyzing the dataset on the...</section>

This study examines if informed trading is present in the index option market by analyzing the KOSPI 200 options, the most actively traded derivative product in the world. The spread decomposition model developed by Madhavan, Richardson, and Roomans (1997) is utilized and the adverse‐selection...

This article empirically examines the lead-lag relations among the KOSPI200 spot market, the KOSPI200 futures market, and the KOSPI200 options market, and provides some explanations for the observed lead-lag relations. In general, the KOSPI200 futures and options markets lead the KOSPI200 spot...

Purpose – The purpose of this paper is to explore unequal dividend payment policies called differentiated dividends (DDs) in Korea. The characteristics of firms are examined which allocate higher dividends to small shareholders than large shareholders within the same share class....

<section xml:id="fut21651-sec-0001"> We examine whether and how investors establish positions in options when they have negative information in the U.S. markets from August 2004 to January 2009. Our empirical results show that options seem to be actively and effectively used for the exploitation of negative information. General...</section>
