Social networks, adoption of improved variety and household welfare: evidence from Ghana

In this study, we examine the effects of own and peer adoption of improved soybean variety on household yields and food and nutrient consumption, using observational data from Ghana. We employ the marginal treatment effect approach to account for treatment effect heterogeneity across households and a number of identification strategies to capture social network effects. Our empirical results show that households with higher unobserved gains are more likely to adopt because of their worse outcomes when not adopting. We also find strong peer adoption effect on own yield, only when the household is also adopting, and on food and nutrient consumption when not adopting. However, the peer adoption effect on consumption attenuates when the household adopts the improved variety. Furthermore, our findings reveal that adoption tends to equalise households in terms of observed and unobserved gains on consumption and can thus serve as a mechanism for promoting food security and nutrition in this area.

Social Studies Textbook Effects: Evidence From Texas

Well-informed decisions on curricular materials can be an efficient way to boost student achievement. Prior studies have employed experimental and quasi-experimental designs to investigate the effects of textbooks on mathematics achievement. This is the first study to consider textbook effects in social studies education. Within the context of a textbook adoption cycle in Texas, we use a difference-in-differences approach with district-level administrative data and estimate the effects of adopting a state-approved textbook on social studies achievement. We find no evidence of a practically meaningful adoption effect. We conclude by highlighting the need for further high-quality research in this often-overlooked school subject area.

A scoping review of feed interventions and livelihoods of small-scale livestock keepers

Livestock support the livelihoods of one billion people in Africa, Asia and Latin America, but the productivity of animals remains low, reducing the potential of the sector to support higher incomes and better nutrition. Improved livestock feeding has been identified as the most important step towards higher productivity. This scoping review assessed the evidence for the uptake of improved ruminant livestock feed options, the effect of this uptake on livestock productivity and the degree to which this improves smallholder farmer livelihoods. In total, 22,981 papers were identified, of which 73 papers were included in the final analysis after a rigorous double-blind screening review. Only papers that reported farmers’ decision to use a new feed intervention were selected, thereby excluding feeding trials and participatory feed assessments. Of the 73 papers, only 6 reported combined evidence of adoption, effect on productivity and livelihood changes. A total of 58 papers looked at adoption, 19 at productivity change and 22 at livelihood change. This scoping review highlights the gap in evidence for the adoption of new livestock feeding practices and provides recommendations to support farmers’ uptake of feed interventions.

Mobile Money, Output and Welfare Among Smallholder Farmers in Ghana

The objective of this study is to examine the impact of mobile money (m-money) adoption on some household outcomes such as farm output, welfare (consumption expenditure), and wealth (value of assets). Using primary data collected from three districts in Ghana, three Propensity Score Matching methods were employed to estimate the m-money adoption effect on the household outcomes. It is found that advertisements and higher than basic levels of education, among other variables, were important in influencing the adoption of m-money among smallholder farmers. The adoption of m-money was also seen to have an enhancing effect on the household outcome variables (farm output, welfare, and wealth) of smallholder farmers. The results suggest that mobile money can help enhance some of the smallholder economic outcomes that are relevant for rural development and poverty reduction. Policy options should consider expanding m-money services to smallholder farmers in rural areas.

The effects of industry characteristics on stock price synchronicity around IFRS adoption

The purpose of this paper is to investigate whether a change in stock price synchronicity after IFRS adoption differs by industry characteristics. IFRS adoption was expected to improve earnings quality and comparability. Industry concentration and homogeneity are utilized as industry characteristics, which are known as determinants to earnings quality and comparability to examine IFRS adoption effect on the synchronicity. Using Korean firms listed from 2006 to 2015, the author found that stock price synchronicity decreases after IFRS adoption. The reduction in synchronicity is larger for firms in a concentrated industry. However, the researcher didn’t find that incremental effect of homogeneity on synchronicity changes around IFRS adoption. These results remain unchanged after several robustness tests. The results imply that earnings quality after IFRS adoption improves, while comparability effect is not evident in the Korean market. The paper has implications that co-movement of stock price decreases after IFRS adoption in that delivering firm-specific information to investors; in addition, the magnitude of impacts of IFRS adoption differs by the industry characteristics. The author extends prior studies about IFRS adoption effect on the capital market by providing that the effects need to be examined after considering the industry characteristics.

Editorial: Multilevel analysis of corporate governance and leadership

The articles included in this volume of the journal discuss a broad variety of topics, including accrual and real earnings management, board of directors’ characteristics, mandatory disclosure of non-financial information, digital transformation strategies of firm leaders, post-adoption effect of alternative performance measures’ guidelines, corporate controlling system expectations, quality of governance frameworks and practices, strategic dividend decisions, network governance, and compliance management. All these aspects continue to make headlines in the popular press and remain topical in the extant corporate governance literature (Bodolica, Dupuis, & Spraggon, 2019).
