The goal of this paper is to analyze the impact of annual earnings announcements on the market through the order flow data in addition to the usual transaction data. In this respect, examining order flow data can potentially reveal valuable information that is not available from transaction data. In fact, the data allow us to test hypotheses about asymmetric information and investor behavior and to test if the behavior varies with investor sophistication. In addition, the paper tries to identify the determinants of the impact on a firm's value using assumptions about investor behavior. 相似文献
Financial theory holds that firms can control agency costs through the use of short-term and secured debt. We examine the relation between the use of secured debt and the incentive of the manager to increase the risk of the firm, as measured by vega. We find that firms utilize secured debt to a lesser extent when managerial volatility sensitivity is higher. Our results suggest that these same firms employ short-term debt as the primary tool to control risk-shifting. Managers with a high risk appetite avoid secured debt, but appear to do so without compromising the interests of the shareholders. 相似文献
Background: Non-vitamin K antagonist oral anticoagulants (NOACs) have been included in international guidelines as important alternatives to vitamin K antagonists (VKAs) for the treatment of venous thromboembolism (VTE) and stroke prevention in non-valvular atrial fibrillation (NVAF). Meanwhile, in the Netherlands, NOACs are widely used next to VKAs. The objective of this study is to estimate the cost-effectiveness of treatment with rivaroxaban compared to VKAs in NVAF and VTE patients in the Netherlands, using data from international prospective observational phase IV studies.
Methods: Two models were developed to represent NVAF and VTE patients, populated with patients from the XANTUS (NCT01606995) and XALIA (NCT01619007) international prospective observational studies. The 1-year cost-effectiveness of rivaroxaban use, compared to VKAs, was explored in a population consisting of NVAF and VTE patients (base case) as well as for four scenarios with sub-populations: NVAF patients only, VTE patients only, NVAF patients with unstable international normalized ratio (INR), and NVAF patients using an INR self-measuring device.
Results: In the base case, rivaroxaban saved €72,350 and gained 21 quality-adjusted life-years (QALYs) in a simulation of 2,000 patients over the use of VKAs. Ergo, rivaroxaban was dominant over VKAs. The probabilistic sensitivity analysis showed a probability of 85% for rivaroxaban being dominant and 100% at a willingness-to-pay threshold of €20,000/QALY. Rivaroxaban appeared to be dominant in all scenarios as well, except for the NVAF-patients-only scenario where the incremental cost-effectiveness ratio (ICER) was €157/QALY.
Conclusions: In patients with NVAF or VTE, rivaroxaban treatment is likely to be cost-effective and a potentially cost-saving alternative to VKA in the Netherlands. 相似文献
This article analyses the impact of Free Trade Agreements (FTAs) on Middle East and North African Countries (MENA) trade for the period 1994–2010. The analysis distinguishes between industrial and agricultural trade to take into account the different liberalization schedules. An augmented gravity model is estimated using up-to-date panel data techniques to control for all time-invariant bilateral factors that influence bilateral trade as well as for the so-called multilateral resistance factors. We also control for the endogeneity of the agreements and test for self-selection bias due to the presence of zero trade in our sample. The main findings indicate that North–South-FTAs and South–South-FTAs have a differential impact in terms of increasing trade in MENA countries, with the former being more beneficial in terms of exports for MENA countries, but both showing greater global market integration. We also find that FTAs that include agricultural products, in which MENA countries have a clear comparative advantage, have more favourable effects for these countries than those only including industrial products. 相似文献
Voter participation rates vary widely across the 50 states and the District of Columbia. This empirical study seeks, within the context of a broadened version of the “rational voter model,” to identify determinants of this geographic variation. Using the 2014 mid-term general election, it was found that the voter participation rate across states and the District of Columbia was positively related to whether there is a close governor’s race or a close U.S. Senate race, the female labor force participation rate, the percent of the population aged 65 and over, the number of referenda on the ballot, and the degree of voting-by-mail usage. In addition, it was found that voter turnout was negatively related to the percentages of the population that are either Hispanic or Afro-American. 相似文献
Helpman, Melitz and Rubinstein [Quarterly Journal of Economics (2008) Vol. 123, pp. 441–487] (HMR) present a rich theoretical model to study the determinants of bilateral trade flows across countries. The model is then empirically implemented through a two‐stage estimation procedure. We argue that this estimation procedure is only valid under the strong distributional assumptions maintained in the article. Statistical tests using the HMR sample, however, clearly reject such assumptions. Moreover, we perform numerical experiments which show that the HMR two‐stage estimator is very sensitive to departures from the assumption of homoskedasticity. These findings cast doubts on any inference drawn from the empirical implementation of the HMR model. 相似文献
In this paper key regulation-related findings and commentaries in the 2016 academic literature are synthesized in annotated form. This paper is one in a series of previously published annotated bibliographies published in this journal. Papers published in academic outlets including The Accounting Review, Journal of Accounting Research, Journal of Accounting and Economics, Contemporary Accounting Research, Accounting Horizons, The Journal of Accounting, Auditing & Finance, Journal of Accounting and Public Policy, Journal of Business, Finance & Accounting, The Journal of Financial Reporting, Auditing A Journal of Practice and Theory, and Research in Accounting Regulation were reviewed for potential inclusion. The 2016 literature featured strong regulation-related threads as follows: financial accounting regulation, analysis of individual pronouncements, SEC regulatory activity and its impact, international financial reporting standards, income tax reporting, and auditing. 相似文献
In 2011, the Spanish government made sustainability accounting mandatory for public sector organizations. This paper documents why, despite the new legislation, the quantity and quality of sustainability accounting practices remains low. 相似文献
The importance of board committees – specialized subgroups that exist to perform many of the board's most critical functions, such as setting executive compensation, identifying potential board members, and overseeing financial reporting – has grown over time due to increased legal requirements and greater complexity of the environment in which firms operate. This has resulted in a large body of work examining board committees across the accounting, finance, and management disciplines. However, this research has developed rather independently within each discipline, preventing scholars and practitioners from developing a comprehensive understanding of board committees. To address this issue, we conduct a comprehensive review of the literature that: 1) summarizes and synthesizes antecedents and outcomes associated with board committees in publicly‐traded firms in English common law countries; and 2) offers a critical analysis of existing research, providing recommendations for advancements and new directions in board committee research. 相似文献
