Abstract

On July 3, 2000, the Jakarta Stock Exchange (JSX) reduced its tick size from Rp25.00 to Rp5.00. This study examines the impact of the tick size reduction on the JSX bid-ask spread, market depth, and trading activity. Using daily data, this study finds that the rupiah spread, percentage spread, and depth decreased significantly. All of these findings are not surprising since they are consistent with previous studies conducted in several different markets.In contrast to previous studies, this study finds that the key variable in determining the difference in performance of JSX stocks following the tick size reduction is the price of the stock. Specifically, all the trading activity measures e.g. in the number of trades, share volume, and rupiah volume, increased for low-priced stocks. Conversely, trading activity decreased for high-priced stocks. The possible explanation is that absolute tick size Rp5.00 is too small in economic terms for JSX high-priced stocks, so those decrease the investors’ willingness to trade.

Abstract

The issue of organizational effectiveness has been one of the most important research subjects sincethe early development of organizational theory. One model widely known in the study of organizationaleffectiveness is competing values framework. Besides that, it is also known that annual report providesinformation to the stakeholders. In order to evaluate organizational effectiveness, this paper discussesthat corporate disclosure could serve as data source to measure many criteria of competing values framework. Apparently, this corporate disclosure based competing values framework is appropriatefor both of the early and the end of organization life cycle. The quantity and quality of disclosures also determine the success of its implementation

Abstract

Stock price crash risk is explained in perspective of corporate governance which refers to the lack of information disclosure. This research investigates the effects of opaque financial reports on stock price crash risk of Indonesia-listed firms from 2005 to 2008.The results show that the degree of crash risk is high. Analyses of binary outcome models, which are controlled by company characteristics, show that crash risk is higher in firms with more opaque financial reports. These results of analysis validate the findings of Hutton et al. (2009) so consistent that insiders or managers hide bad news or negative information when submitting poor financial reports.
