Do management reports on internal control over financial reporting improve financial reporting?

Sections 404a and 404b of the Sarbanes–Oxley Act require management and external auditors, respectively, to report on the adequacy of a company’s internal control over financial reporting (ICFR). Larger public firms were first required to file a management report and have an external audit of ICFR in 2004. Smaller public firms were first required to file a management report on ICFR in 2007 but are exempt from the attestation requirement. We investigate the distinct effect of management reports on financial reporting quality. We find that management reports on ICFR improve reporting quality and demonstrate that there are financial reporting benefits from the management report requirement on its own without attestation.     

Impact of short selling activity on market dynamics: Evidence from an emerging market

With unique daily short sale data of Borsa Istanbul (stock exchange of Turkey), we investigate the dynamic relationship between short selling activity and volatility, liquidity and market return from January 2005 to December 2012 using a VAR(p)-cDCC-FIEGARCH(1,d,1) approach. Our findings suggest that short sellers are contrarian traders and contribute to efficient stock market in Turkey. We also show that increased short selling activity is associated with higher liquidity and decreased volatility. However this relation weakens during the financial turmoil of 2008. Our results indicate that any ban on short sales may be detrimental for financial stability and market quality in Turkey.     

Atributos relevantes de calidad en el servicio y su influencia hacia la lealtad de marca en la industria aseguradora de automóviles en México

The objective of this study is to identify key quality service attributes in the automobile insurance business and determine their influence on brand loyalty. In this study distinction is made between the service during the hiring of the service and the service provided after an accident. In a preliminary exploratory inquiry quality service attributes were identified with the application of in-depth interviews. In an empirical study, hypothesis related to a direct relationship between the attributes and several measures of brand loyalty are contrasted. A sample of n = 210 of automobile insurance clients was conformed. Five regression models were developed for the data analysis, one for each loyalty measure. These analyses allowed a specific detection of significant attributes for each case. Though it is concluded that attributes related to the service after the accident have a higher degree of influence on the customer loyalty, it is found that a particular attribute during hiring (reputation of the insurance company) also has an important role.     

Subprime cohorts and loan performance

Loan performance of subprime originations during the boom years of 2004–2006 is contrasted with that of subprime originations during the early period of 2000–2002. A counterfactual technique is developed to determine how originations during the early period would perform in a different environment, namely, the environment faced by originations of 2004, 2005, and 2006. In an environment where house prices are increasing rapidly, low credit score originations do not show high rates of default—as was witnessed for 2000–2002 cohorts. However, in an environment of stagnant or deteriorating home prices, low credit score originations show significantly higher rates of default than high credit score originations. With a greater proportion of low credit score originations, earlier cohorts of 2000–2002 were no less vulnerable to the environment faced by cohorts of 2004–2006. In essence, these results raise concerns about the viability of all cohorts of subprime originations because of their reliance on the appreciation of the underlying collateral rather than the creditworthiness of the borrower.     

Upper‐echelon executive human capital and compensation: Generalist vs specialist skills

This study extends current knowledge of upper echelon executive compensation beyond the CEO, specifically CFO compensation, based on whether they possess generalist or specialist skills. We find that “strategic” CFOs with an elite MBA (generalist) consistently command a compensation premium, while “accounting” CFOs (specialist) and CFOs with a non‐MBA master's degree, even from an elite institution, do not. Further, scarce “strategic” CFOs are awarded both higher salaries and higher equity‐based compensation. Our findings support the view that unique complementarities between scarce CFOs and firms increase these executives' bargaining power leading to pay premium. Our results are robust to post‐hiring years, firm sizes, board characteristics, and CFO's insider/outsider status. We contribute at the confluence of upper‐echelon compensation, executive human capital, resource‐based view, and assortative matching literatures. Copyright © 2014 John Wiley & Sons, Ltd.
