Employee ownership and firm performance: a meta‐analysis

Employee ownership has been an area of significant practitioner and academic interest for the past four decades. Yet, empirical results on the relationship between employee ownership and firm performance remain mixed. To aggregate findings and provide potential direction for future theoretical development, we conducted a meta‐analysis of 102 samples representing 56,984 firms. Employee ownership has a small, but positive and statistically significant relation to firm performance ( = 0.04). The effect is generally positive for studies with different sampling designs (samples assessing change in performance pre‐employee–post‐employee ownership adoption or samples on firms with employee ownership), different performance operationalisation (efficiency or growth) and firm type (publicly held or privately held). Suggesting benefits of employee ownership in a variety of contexts, we found no differences in effects on performance in publicly held versus privately held firms, stock or stock option‐based ownership plans or differences in effects across different firm sizes (i.e. number of employees). We do find that the effect of employee ownership on performance has increased in studies over time and that studies with samples from outside the USA report stronger effects than those within. We also find little to no evidence of publication bias.     

Skin Tone and Self-Employment: is there an Intra-Group Variation among Blacks?

The purpose of this paper is to formally evaluate whether odds of entry into self-employment decrease as skin tone darkens for Blacks in the United States. Extending past work on inter-group differences in Black-White self-employment, based on data from National Longitudinal Survey of Youth 1997, with darker skin tone the odds of self-employment decline. Having spent more time in labor force further decreases the likelihood of self-employment for darker skin tone Blacks, and being a high-school graduate, scoring high on Armed Services Vocational Aptitude Battery (ASVAB), or higher past year income are not associated with self-employment of darker skin tone Blacks. While darker skin tone Blacks who are self-employed derive lower income, those who are self-employed and with more human capital (longer time spent in the labor force, scoring high on ASVAB or being a high school graduate) have a higher income.     

Gender and child sensitive social protection in South Africa

Drawing from a 2010 study of women receiving the Child Support Grant in an urban area of South Africa, this article discusses the link between social protection, women's empowerment and the well-being of children. It appears that the Grant enhances women's power and control over household decision-making in financial matters, general household spending and child well-being. At the same time, the data show that women continue to bear the greatest burden of care in the household and that these responsibilities significantly heighten gender inequalities. Therefore, while the Grant has benefits for child well-being and women's empowerment, it cannot on its own transform unequal and unjust social relations of power. It should be working in concert with other public programmes not only to focus on children's needs but also to strive for gender equality for poor women.     

The Effect of Accounting Education and National Culture on Accounting Judgments: A Comparative Study of Anglo-Celtic and Chinese Culture

Countries adopting International Financial Reporting Standards (IFRS) need to educate and train their professional accountants so that they are able to interpret and apply IFRS in a consistent manner. This study examines the effect of national culture and education on the judgments of Australian (Anglo-Celtic) and Chinese final year undergraduate accounting students in Australia. It seeks to understand whether culture influences student interpretation and application of uncertainty expressions, which are used as recognition and disclosure thresholds in IFRS. Results obtained on the cultural dimensions of Uncertainty Avoidance, Individualism, Power Distance, Masculinity and Long-Term Orientation provide evidence that Chinese students exhibit greater conservatism and secrecy compared to Australian students. The results of the study indicate that national culture has a significant effect on the judgments of accounting students when interpreting and applying selected IFRS containing uncertainty expressions. The results also imply that educational similarity does not moderate the effect of culture in influencing the judgments of accounting students. An important implication of the study is that regulators and standard-setters involved in the international convergence of accounting standards need to pay greater attention to cultural factors that may result in a difference in the interpretation and application of IFRS.     

Cost-utility analyses of targeted immunomodulators in rheumatoid arthritis: systematic review

Abstract

Aims: Cost-utility (CU) modeling is a common technique used to determine whether new treatments represent good value for money. As with any modeling exercise, findings are a direct result of methodology choices, which may vary widely. Several targeted immuno-modulators have been launched in recent years to treat moderate-to-severe rheumatoid arthritis (RA) which have been evaluated using CU methods. Our objectives were to identify common and innovative modeling choices in moderate-to-severe RA and to highlight their implications for future models in RA.

Materials and methods: A systematic literature search was conducted to identify CU models in moderate-to-severe RA published from January 2013 to June 2019. Studies must have included an active comparator and used quality-adjusted life-years (QALYs) as the common measure of effectiveness. Modeling methods were characterized by stakeholder perspective, simulation type, mapping between parameters, and data sources.

Results: Thirty-one published modeling studies were reviewed spanning 13 countries and 9 drugs, with common methodological choices and innovations observed among them. Over the evaluated time period, we observed common methods and assumptions that are becoming more prominent in the RA CU modeling landscape, including patient-level simulations, two-stage models combining trial results and real-world evidence, real-world treatment durations, long-term health consequences, and Health Assessment Questionnaire (HAQ)-related hospitalization costs. Models that consider the societal perspective are increasingly being developed as well.

Limitations: This review did not consider studies that did not report QALYs as a utility measure, models published only as conference abstracts, or cost-consequence models that did not report an incremental CU ratio.

Conclusions: CU modeling for RA increasingly reflects real-world conditions and patient experiences which are anticipated to provide better information in the assessment of health technologies. Future CU models in RA should consider applying the observed advances in modeling choices to optimize their CU predictions and simulation of real-world outcomes.     

JUNK BOND BEHAVIOR WITH DAILY RETURNS AND BUSINESS CYCLES

Using the Merrill Lynch daily junk bond index, we re-examine and extend previous junk bond return results. We include the effect of business cycles on junk and investment-grade bonds, the sensitivity of junk bond returns to economic activity and/or interest rates, and sample periods that allow us to investigate periods of reduced junk bond liquidity. Daily data confirm the same curious return behavior identified in studies using monthly returns. However, we reveal for the first time that junk bond returns track the movement of interest rates during economically good times but track stock returns during bad times.     

How do young firms manage product portfolio complexity? The role of absorptive capacity and ambidexterity

Building a complex portfolio of products can be beneficial for young firms due to increased sales growth and competitiveness. Yet, the benefits from product portfolio complexity (PPC) are often outweighed by rising costs, leading to an inverted U‐shaped relationship between PPC and performance. Recent research has called for an increased understanding of how firms are able to better manage higher levels of PPC. We suggest that absorptive capacity and ambidexterity are vital to enhancing the benefits and mitigating the costs of increasing PPC. Using a sample of 215 young high technology firms, we find support for positive moderating effects of absorptive capacity and ambidexterity on the inverted U‐shaped relationship between PPC and firm performance.
