Does Ownership Identity Matter? A Meta‐analysis of Research on Firm Financial Performance in Relation to Government versus Private Ownership

We examine whether reported ownership–performance relations systematically differ for government versus private ownership by integrating the diverse empirical results for listed corporations in emerging markets. Our meta‐analysis confirms popular perceptions that, compared to private ownership, government ownership is associated with inferior performance. We find that, on average, the underlying ownership–performance relation is negative for government ownership and positive for private ownership, and the difference between these relations is significant. We also find that the positive private ownership–performance relation is stronger for institutional/foreign ownership compared to family/management ownership. Further analysis shows that negative (positive) government (private) ownership and performance relations have weakened (strengthened) over time. Our assessment of the sources of heterogeneity shows that reported relations are biased by estimation methods that fail to adequately control for endogeneity. Our results suggest that the nature of ownership–performance relations in emerging markets remains very dynamic and warrants ongoing research interest.     

Components of CEO Remuneration and Non‐GAAP Disclosure

This paper provides evidence of the effect of chief executive officer (CEO) remuneration on decisions to disclose voluntary non‐generally accepted accounting principles (non‐GAAP) financial measures. We investigate profit announcements that focus on the most emphasised part, which includes mandatorily identified information (results for the announcement to the market) and the least emphasised part, which incorporates other sections. By reading the profit announcements and manually collecting non‐GAAP financial measures (NGFM) data, there is no reliance on keyword search strings and as such we uncover the pervasiveness of the use of NGFM. Results show that the base component of CEOs’ remuneration plays a significant role in reporting NGFM in the most emphasised part of the profit announcement. Conversely, all three (base, short‐term and long‐term incentives) components of the remuneration package have a significant relationship with the reporting decisions in the least emphasised part of the statement. We find that, depending on the regulatory imposition and the emphasis assigned to the section of the profit announcement, the motive for voluntary disclosure of NGFM can be explained as altruistic (informative) or opportunistic (misleading). We contribute evidence on ‘pay–action’ rather than ‘pay–performance’ by incorporating all three components simultaneously into the framework to maintain the assumption of correspondence and internal consistency among those components.     

Predictors of glycemic control and diabetes-related costs among type 2 diabetes patients initiating therapy with liraglutide in the United States

Objective:

Liraglutide has been shown to significantly improve glycemic control and reduce body weight while minimizing the risk of hypoglycemia in adult patients with type 2 diabetes (T2D). This study aimed to identify characteristics that predict clinical and economic outcomes associated with liraglutide therapy in clinical practice in the US.

Methods:

Using the Truven Health MarketScan Laboratory Database, glycemic control (A1C <7%) and diabetes-related costs were evaluated in T2D patients initiating liraglutide between January 1, 2010 and June 30, 2012. Patients were required to have ≥1 post-index claim for liraglutide and A1C values at baseline and 6 months follow-up. All valid values of baseline A1C were included. Patients previously treated with GLP-1 receptor agonist(s) or insulin, or with evidence of type 1 diabetes, pregnancy, or gestational diabetes during the study period were excluded. Multivariable regression models were used to identify predictors of glycemic control and diabetes-related costs.

Results:

Of 417 patients newly treated with liraglutide, 54.0% achieved glycemic control (A1C <7%) during follow-up. Factors associated with increased odds of glycemic control during follow-up were: being female, POS/EPO health plan type, baseline A1C, early liraglutide initiation (0–1 prior oral anti diabetics [OADs] vs ≥2), adherence to liraglutide (defined as the proportion of days covered [PDC]), and diabetic retinopathy. Being female, earlier liraglutide initiation (0–1 prior OADs), and higher patient share of liraglutide costs were associated with significantly lower diabetes-related costs during follow-up. Factors associated with significantly higher post-index diabetes-related costs were: higher baseline A1C, baseline use of sulfonylureas, and diabetic retinopathy.

Conclusions:

Within this commercially-insured population of T2D patients treated with liraglutide, gender, baseline A1C, early liraglutide initiation (0–1 prior OADs), diabetic retinopathy, better adherence, and patient share of liraglutide costs were associated with increased odds of achieving glycemic control and the odds of having higher or lower diabetes-related costs.     

Linking technical change to research effort: an examination of aggregation and spillovers effects

We used a disaggregate approach to examine investment efficiency of wheat breeding research in India. India's total research effort comprizes 20 research programs spread across 50 experiment stations. A technology spillover matrix was constructed for both potential and actual spillovers. Spillovers and free‐riding were dominant characteristics of technical change during the period studied. Although the aggregate rate of return to wheat improvement research in India was estimated to be 55%, eight programs were found to have earned a negative rate of return when spillins were taken into account. Research output is concentrated on a few strong programs. The two strongest programs generated 75% of all the technical change benefits, even though they claimed just 22% of research resources. These two programs include a significant degree of overlap, while on the other hand many farmers were not reached by any of the programs – 56 and 78% of rainfed and durum area, respectively, in 1990 was still sown with pre‐1976 varieties.     

Exclusionary discounts

We consider a two-period model with two sellers and one buyer. Although we assume it is efficient for the buyer to purchase from both sellers in each period, we show that when the buyer's valuations are inter-temporally linked and at least one seller is financially constrained, exclusion can sometimes arise in equilibrium (i.e., the buyer purchases all of its requirements from the same seller in each period). The exclusionary equilibria are supported by contract offers in which the excluding seller's incremental price to supply the contestable part of demand is below its marginal cost and sometimes negative. Our findings contribute to the literatures on market-share contracts, bundling, all-units discounts, and loyalty discounts.

Modeling marketplace behavior

Marketplace behavior refers to aspects of the purchase behavior of individuals and firms that leads to marketplace demand. It is characterized by the presence of many variables, most of which have nothing to do with a specific venture or specific consumer. This paper discusses three challenges of analysis commonly found in quantitative models of marketplace data: heterogeneous consumers, goal-directed behaviors, and the selective attention to some but not all variables in extended models of behavior. Bayesian solutions to these challenges are discussed.     

A comparison of business ethics commitment in private and public sector organizations in Sweden

This paper reports the results of a study of the top 500 private sector organizations and the top 100 public sector organizations in Sweden. It is a replication of the study by Svensson et al. (2004) . The aim of the study was to describe and compare the business ethics commitment of organizations across the two sectors. The empirical findings indicate that the processes involved in business ethics commitment have begun to be recognized and acted upon at an organizational level in Sweden. Some support is provided to show that codes of ethics are developing in some of Sweden's largest private and public sector organizations – although this is happening to a lesser extent in the public sector. It is noted that an effect of a code of ethics on the bottom line of the business was acknowledged by respondents in both private and public sector organizations. We believe that the supporting measures of business ethics commitment appear to be underutilized in both private and public sector organizations in Sweden (among those that possess codes of ethics), thus indicating that the commitment to business ethics in Swedish organizations has potential for future development.     

OWNERSHIP CONCENTRATION AND FIRM PERFORMANCE IN EMERGING MARKETS: A META‐ANALYSIS

The literature concerned with relations between ownership concentration and corporate performance in emerging markets presents conflicting theoretical predications and inconclusive empirical results. We use meta‐analytical techniques to integrate the diverse empirical findings and investigate factors contribute to the inconsistencies in the empirical evidence. Using 419 correlations collected from 42 primary studies of listed corporations in 18 emerging markets, heterogeneity tests show that only a small proportion of the variation in reported ownership concentration–performance relations can be attributed to sampling error. Our meta‐regressions reveal how population differences, researchers’ modeling choices, and inadequate treatment of endogeneity explain a large portion of the true heterogeneity. After adjusting for these effects, we find ownership concentration has negative relation with firm performance across countries. Our results emphasize the importance of model specification and methods of addressing endogeneity, and support further comparative study of the ownership concentration–corporate performance relation between countries with seemingly similar corporate governance environments.
