Human resource information systems: Information security concerns for organizations

We explore HRIS and e-HR security by presenting information security fundamentals and how they pertain to organizations. With increasing use of enterprise systems such as HRIS and e-HR, security of such systems is an area that is worthy of further exploration. Even then, there is surprisingly little research in this area, albeit that extensive work is present in regard to HRIS privacy. While focusing on HRIS and e-HR security, we introduce aspects of HRIS and e-HR security and how it can be enhanced in organizations. A research model is also presented along with propositions that can guide future research.     

A comparison of treatment effects estimators using a structural model of AMI treatment choices and severity of illness information from hospital charts

We compare the performance of various matching estimators using a novel approach that is feasible in the absence of experimental data. We estimate a structural model of hospital choices and catheterization for Medicare heart attack victims using hospital chart data on patient heterogeneity. With the estimated structural parameters, we simulate data for which the treatment effect is known. We find that as measures of individual heterogeneity are added to the controls, matching estimators perform well. However, the estimators do a poor job recovering the true treatment effect when measures of individual heterogeneity are unavailable. Copyright © 2010 John Wiley & Sons, Ltd.     

An Empirical Investigation of the Effect of CFO Power on Disclosure Quality

We examine the association between chief financial officer (CFO) power and disclosure quality, measured using financial statement disaggregation disclosure and analyst forecast disclosure. Empirically, we validate that CFO power, measured by multiple dimensions, is positively associated with firms’ disclosure quality. We also find that this positive association between CFO power and disclosure quality is stronger when firms exhibit higher governance monitoring and accounting quality. Further analysis shows that our main results hold across multiple disclosure quality tests. Our findings are robust to addressing endogeneity issues using two-stage least squares, Heckman selection bias, and propensity score matching analyses. The results highlight the importance of CFO power for the accounting reporting process and decision-making.     

Immigrants’ Wage Performance in a Routine Biased Technological Change Era: France 1994–2012

Over the period 1994–2012, immigrants’ wage growth in France outperformed that of natives. We investigate to what extent changes in task‐specific returns to skills contributed to this wage dynamics differential through two channels: changes in the valuation of skills (price effect) and occupational sorting (quantity effect). We find that the wage growth premium of immigrants is mainly explained by the progressive reallocation of immigrants toward tasks whose returns increase over time. Immigrants seem to have taken advantage of labor demand restructuring driven by globalization and technological changes.

Political change and informality

This paper examines informality during the political and economic turmoil that accompanied the Arab Spring revolution in Egypt. The paper focuses on unprotected employment and the extent to which it changed by educational level immediately after the January Uprising of 2011. We find that over time and particularly after the revolution, informal employment has increased for both high‐ and low‐educated workers, albeit through different paths: high‐educated workers were more likely to be stuck in informality, while low‐educated formal workers were more likely to lose their contracts. The increase in informal employment in the wake of the Arab Spring is more pronounced for the high‐educated. The results suggest a high level of rigidity in the Egyptian labour market, even in the wake of the Arab Spring.

How costly is the Sarbanes Oxley Act? Evidence on the effects of the Act on corporate profitability

The Sarbanes-Oxley Act (SOX) was intended to protect investors by improving the accuracy and reliability of corporate disclosures. However, critics have argued that the costs of SOX far outweigh its intended benefits. Prior studies based on stock-price reactions to SOX-related events document mixed evidence on the expected impact of SOX. In contrast, we provide evidence on the net realized costs of SOX by examining its impact on operating profitability. We find that average cash flows decline by 1.3% of total assets after SOX. These costs are more significant for smaller firms, for more complex firms, and for firms with lower-growth opportunities. Annually, these costs range from $6 million for smaller firms to $39 million for larger firms. Further, we document that net SOX-related costs are not limited to one-time expenses associated with internal-control design and implementation. In aggregate, for the 1428 firms in our sample, these costs amount to about $19 billion per year. Profitability is lower for up to four years post-SOX. To our knowledge, ours are the first estimates of the realized net costs imposed by SOX.
