Initial public offerings (IPOs) are typically offered at prices lower than the transaction price in the early aftermarket. With a stochastic frontier model, we measured the fair offer price of an IPO and then the deliberate IPO underpricing and the market misvaluation based on the estimated fair offer price. Our results show that IPOs are deliberately underpriced. The extent of noisy trading leading to significantly higher market transaction prices explains the excess IPO returns. We conclude that initial IPO returns result primarily from the noisy trading activities instead of the deliberate IPO underpricing.  相似文献

Valuation of vulnerable American options with correlated credit risk   总被引:1,自引:0,他引:1  
This article evaluates vulnerable American options based on the two-point Geske and Johnson method. In accordance with the Martingale approach, we provide analytical pricing formulas for European and multi-exercisable options under risk-neutral measures. Employing Richardson’s extrapolation gets the values of vulnerable American options. To demonstrate the accuracy of our proposed method, we use numerical examples to compare the values of vulnerable American options from our proposed method with the benchmark values from the least-square Monte Carlo simulation method. We also perform sensitivity analyses for vulnerable American options and show how the prices of vulnerable American options vary with the correlation between the underlying assets and the option writer’s assets.   相似文献

乡镇财政自给能力分析   总被引:1,自引:0,他引:1  
乡镇财政危机目前作为一个重要问题成为各界关注焦点,乡镇财政赤字和负债数额巨大,乡镇财政自给程度到底有多大,本文运用财政能力系数指标来定量探讨乡镇财政的危机程度,通过全国五级财政自给系数纵向对比、分省区四级财政自给能力纵向和横向对比以及两个乡镇个案的财政自给系数,来揭示乡镇财政危机的制度内涵.  相似文献

Using a sample of eight large commercial banks from 1994 to 2000, Jorion (2002) finds that banks' VaR disclosures for their trading portfolios predict trading income variability. We extend Jorion's findings using a larger sample of 17 banks from 1997 to 2002 reporting trading VaRs under FRR No. 48 (1997). We find that banks' trading VaRs have predictive power for trading income variability that increases with bank technical sophistication and over time. We find that banks' trading VaRs have predictive power for a bank-wide measure of total risk, return variability, and for two bank-wide measures of priced risk, beta and realized returns.  相似文献

Enterprise risk management (ERM) is a process that manages all risks in an integrated, holistic fashion by controlling and coordinating any offsetting risks across the enterprise. This research investigates whether the adoption of the ERM approach affects firms' cost of equity capital. We restrict our analysis to the U.S. insurance industry to control for unobservable differences in business models and risk exposures across industries. We simultaneously model firms' adoption of ERM and the effect of ERM on the cost of capital. We find that ERM adoption significantly reduces firm's cost of capital. Our results suggest that cost of capital benefits are one answer to the question how ERM can create value.  相似文献

We study pricing strategies of competing firms selling heterogeneous products to consumers. Goods are substitutes and there are network externalities between neighboring consumers. In equilibrium, firms price discriminate based on the network positions and charge lower prices to more central consumers. We also show that, under some conditions, firms' equilibrium profits decrease when either the network becomes denser or network effects increase. In contrast, consumers always benefit from being more connected to each other. We determine the optimal network structure and compare uniform pricing and discriminatory pricing from the perspectives of firms and consumers.  相似文献

This paper examines whether Internet access positively affects credit card balances. To that end, we compare the 2010 and 2013 Surveys of Consumer Finances, analyze the consistency of the results over time, and provide the rationale for any resulting differences. Using the censored techniques, our results indicate that Internet access has a positive effect on credit card balances, which suggests that consumers with Internet access are prone to higher balances compared to those without. The probability of carrying positive balances was larger in 2010 compared to 2013. Overall, the results suggest that, while the financial crisis might have contributed to higher balances in 2010, the economic recovery afterward seems to have eased the burden of credit card debt.  相似文献

This paper brings together research on boards of directors as the backbone of corporate governance and corporate social responsibility (CSR) practices in the banking industry. The underlying idea is that some characteristics of bank boards, in particular independence and gender diversity, may impact the CSR commitments of banks. By making use of a sample of 159 banks in nine countries during the period 2004–2010, our empirical evidence suggests that banks with more independent directors and more female members on their boards incline toward socially responsible behaviour. Our results also suggest that institutional factors play a significant role in these effects. They show that in greater regulatory and stronger investor protection environments, board independence and gender diversity have more influence on the social behaviour of banks.  相似文献

The aim of this study is to research the adoption of International Financial Reporting Standards (IFRS) in Jordan, which was one of the first Middle Eastern emerging economies to adopt IFRS. The paper investigates the related factors that pressure and prevent such adoption over time, and illustrates the developmental aspects of such adoption. An interpretive methodology is employed, and perceptions of the study's participants are analysed regarding the adoption of IFRS in Jordan, which is an area that is under researched. Semi‐structured interviews were undertaken to collect Jordanian experts’ perceptions. Based on the empirical data analysis and prior theoretical and empirical literature, an adoption model was developed, which can serve future studies as well. The model illustrates the paradox of accounting changes in emerging economies, in which the actual conditions that pressure IFRS adoption are also the conditions that prevent full adoption. The model also provides an explanation of the implementation process of IFRS in emerging economies at both country and corporation levels. It combines practical features and related theories in an integrative model seeking to explain the phenomenon of IFRS as a new accounting regulation change.  相似文献
