本研究旨在探討市場擇時效果(market timing)對資本結構的影響,Hovakimian(2006)指出使用市價淨值比(M/B ratio)並不是探討市場擇時效果的良好指標。因此本研究擬採用Alti(2006)市場擇時模型,以熱變數(hot variables)探討市場擇時理論於東南亞市場的適用性;其次以Pagan and Sossounov(2003)提出的修正之B-B法計算股市景氣週期循環的方法,作為區分出景氣的熱市(hot market)與冷市(cold market)的指標。本研究發現不論以Alti(2006)或依修正之B-B法定義熱變數在馬來西亞、新加坡、印尼、印度、南韓的資本市場具擇時效果皆較有解釋能力;而臺灣與菲律賓的資本市場則不存在市場擇時效果。此外,就各國的個別市場而言,以南韓的資本市場之市場擇時效果最為顯著;就公司面的熱市與冷市場而言香港與新加坡的解釋能力較弱;而泰國與印尼則在市場擇時效果對資本結構的持續性衝擊上較無解釋能力。
The present study empirically investigates the market timing ability on capital structure. Hovakimian(2006) pointed out the market-to-book ratio is not a crucial indicator in measuring the market timing. First, we adopt the market timing model developed by Alti(2006), who used hot variables to measure the market timing effect. Then, we employ the B-B algorithm by Pagan and Sossounov(2003) to define the stock markets as a hot or cold scenario in a business cycle. We find that the market timing ability of capital market prevails in southeast Asia countries except Taiwan and Philippines both in terms of the market timing model by Alti(2006) or the B-B algorithm model by Pagan and Sossounov(2003). Especially South Korea has the most strong market timing effect. On the contrary, the market timing effect is much weaker in capital market in Kong Hong, Singapore, Thailand, and Indonesia.
