ABSTRACT
This paper provides a first attempt to analyze the long-run adjustment towards the target for Asian firms. Annual data from 1980 to 2003 of five Asian economies including Hong Kong, Japan, Singapore, Taiwan and Thailand are extracted from the PACAP database. Our sample includes 386 firms from Hong Kong, 1,722 firms from Japan, 158 firms from Singapore, 191 firms from Taiwan and 261 firms from Thailand. The partial adjustment models for book leverage and market leverage are estimated. Results show that the leverage ratios of Asian firms adjust gradually towards their target levels. Significant deviations from target due to the pecking order and market timing effects are found. In contrast to Kayhan and Titman (2007), we show that the market timing behavior does not persist. It is also found that Asian firms tend to use more debt than equity when external funding is needed.

1. INTRODUCTION
How firms arrive at their optimal capital structure is a question of debate. Three major hypotheses, namely, the pecking order hypothesis, trade-offhypothesis and market timing hypothesis, have been put forward in the literature to explain the optimal capital structure of a firm.
The pecking order hypothesis (Donaldson, 1961; Myers, 1984) states that firms prefer internal financing by retained earnings to external financing and prefer debt to equity for external financing. Donaldson (1961) and Myers (1984) use the historical profit as a proxy of internal funds to test for the pecking order effect. If a firm prefers to use internal funds, the increase in the past earnings before interest and taxes (EBIT) tends to lower the debt ratio. Shyam-Sunder and Myers (1999), Frank and Goyal (2003) and Brounen et al. (2006) present evidence of firms' pecking order behavior.
The trade-offhypothesis implies that firms make the capital structure decision based on the cost and benefit of different sources of financing. An optimal (target) leverage ratio is achieved when the marginal cost and marginal benefit of using extra debt and equity are equal.
Baker and Wurgler (2002) propose the market timing hypothesis that firms prefer to issue equity when the market overvalues the equity relative to the book value and to repurchase equity when the shares are undervalued.1 The...
