We examine the twin roles of accountability and value enhancement of corporate governance in the context of financial reporting. We investigate the accountability role by examining the association between governance structures and abnormal accruals, and the value enhancement role by investigating the association between abnormal accruals explained by governance structures and future performance. We differentiate between governance mechanisms that have direct roles in the financial reporting process (audit related) from mechanisms that have indirect roles (board related). We find that independent and active audit committees and independent boards are important governance attributes for financial reporting. We show that both audit‐related and board‐related governance structures are value enhancing. 相似文献

This study tests the validity of the critical assumption underlying the option pricing model that the log form of the stock price movements follows the Wiener process, i.e., stock price movements follow a geometric Brownian motion. Using data compiled from the Taiwan Stock Exchange (TSE), this study's major empirical findings are as follows: first, the null hypothesis that the log of the stock prices is normally distributed is rejected; second, the null hypothesis that the stock price in log form has mean [ln P
s
+ (µ-
2)t] and variance t is rejected; third, the null hypothesis that successive non-overlapping increments of the log of the stock price are independent from each other is also rejected. These empirical findings undermine the validity of the Wiener process assumption which is fundamental to many option pricing models. 相似文献

We use Bayesian structural time series (BSTS) methodology to test whether the Wall Street Reform and Consumer Protection Act of 2010 (DF) caused changes in community bank business models. The BSTS methodology uses the pre-DF period to create synthetic counterfactuals for community-bank dependent variables of interest. In the post-DF period, the counterfactuals become predictions of the dependent variables had DF not been enacted. Comparing post-DF predicted versus actual dependent variables allows us to estimate the causal impact of DF on these variables of interest. We find that relative to assets, community banks significantly reduce their lending activities and significantly increase investment in securities and excess reserves. 相似文献

In recent years, many initial coin offerings (ICOs) scams have been reported, attracting attention to this relatively new and unregulated ICO market, which lacks disclosure requirements and therefore suffers from intensifying problems of information asymmetry inherent in crowdfunding. As a prospectus-type document, an ICO white paper serves as a major means of voluntary disclosure practices adopted by ventures seeking external financing. Given the importance of an ICO white paper and the difficulty of assessing its quality, we propose to benchmark it against white paper content for security token offerings (STOs)—a more regulated ICO subset. Using the similarity of ICO white papers with STO white papers to proxy for disclosure quality, we document that the ICO campaigns that have white papers more similar to STO white papers are more likely to raise funding successfully. Our findings provide implications for policymakers, ICO fundraisers, and investors on the importance of white paper quality. 相似文献

In this paper, we empirically investigate the relationship between the convenience yield of government bonds and the real exchange rates using monthly data from 1999 to 2018. We extend the conventional models, based on the present-value relationship between the real exchange rate and economic fundamentals, while explicitly considering the role of the convenience yield. Empirical results suggest that our present-value models can capture the dynamic properties of the real exchange rate documented in the literature, including high persistence, excess volatility and excess co-movement compared with real interest rate differentials. We also find that the sum of expected convenience yields significantly drives real exchange rate movements. Moreover, we find that foreign exchange swap market friction also plays a role in explaining real exchange rates. Finally, we find that monetary policy at the zero lower bound may be essential in real exchange rate modelling. 相似文献
