The authors propose a strategy for studying the effects of time-varying instructional treatments on repeatedly observed student achievement. This approach responds to three challenges: (a) The yearly reallocation of students to classrooms and teachers creates a complex structure of dependence among responses; (b) a child’s learning outcome under a certain treatment may depend on the treatment assignment of other children, the skill of the teacher, and the classmates and teachers encountered in the past years; and (c) time-varying confounding poses special problems of endogeneity. The authors address these challenges by modifying the stable unit treatment value assumption to identify potential outcomes and causal effects and by integrating inverse probability of treatment weighting into a four-way value-added hierarchical model with pseudolikelihood estimation. Using data from the Longitudinal Analysis of School Change and Performance, the authors apply these methods to study the impact of “intensive math instruction” in Grades 4 and 5.

Abstract Background Research finds center-based child care typically benefits children of low socio-economic status (SES) but few studies have examined if it also reduces inequalities in developmental disadvantage. Objective I test if the length of time in center-based care between ages one and three years associates with child development scores at age three years, focusing on the impact for groups of children in the lower tercile of child development scores and in the lower SES tercile. Method Using data from 1,606 children collected in a nationally representative Chilean survey, I apply a value-added approach to measure gains in child development scores between age one and three years that are associated with length of time in center-based child care. Results Disadvantages at age one year were associated with lower child development scores at age three years. No benefits of additional time in center-based care were found for the non-disadvantaged group, but positive associations were found between more time in center-based care and child development outcomes for children with the SES disadvantage only. Center-based care was not associated with child development trajectories of children with lower child development scores at age one year, no matter their SES status. Conclusions There is evidence that Chilean center-based child care reduces SES inequality in child development scores between ages one and three years, but only if children already were not low-scorers at age one year.

The Impact

Considering the possibility of finding a gap and a room for improvement, so much have been written about liquidity and performance. Notwithstanding, the emphasis has been on profitability as a yardstick for performance and little has been done on other areas of performance measurement. The emphasis has also been more on various economic sectors with the exception of the manufacturing industry. This paper intends to look at the impact, if any, of liquidity provision and availability on Nigeria’s manufacturing firm’s performance from the perspective of Economic Value Added (EVA). Economic value-adding is beyond just profitability or liquidity. The firm's value to the stakeholders, its sustainability and long-term values are defined. The study would apply liquidity theories, profitability and the economic value-added theories as it applies to a manufacturing firm in a developing economy like Nigeria. On its methodology, the article data is obtained from the World Bank’s World Development Indicators-WDI and then a regression analysis will be run on the data using the SPSS software and then an analysis of the results of the regression. The last section of the article would conclude and make recommendations from the study outcome and the empirical analysis with respect to the theories.

This paper investigates the impact of having open 400 meter (400 m) runners on NCAA relay teams. Using data from 2012–2016 containing the top 100 4 × 400 m in each NCAA Division relay times for each year, it is found that more 400 m specialists lead to an increase in the overall performance of the team, measured by a decrease in relay times. The effect is examined across Division I–III NCAA track teams. The results are consistent across each division. We view this as a test of the role of specialization on performance. Using runners who specialize in 400 m races should increase overall team performance as long as specialization does not lead to an inefficient allocation of team human capital. An additional performance measure is used examining the difference between projected and actual relay times. Divisions I and II are found to perform better than projected with an increase in 400 m runners, but there is no effect found in Division III.

The Impact

With distributed teams becoming increasingly common in organizations, improving their performance is a critical challenge for both practitioners and researchers. This research examines how group members' perception of subgroup formation affects team performance in fully distributed teams. The authors propose that individual members' perception about the presence of subgroups within the team has a negative effect on team performance, which manifests itself through decreases in a team's transactive memory system (TMS). Using data from 154 members of 41 fully distributed teams (where no group members were colocated), the authors found that members' perceptions of the existence of subgroups impair the team's TMS and its overall performance. They found these effects to be statistically significant. In addition, decreases in a group's TMS partially mediate the effect of perceived subgroup formation on team performance. The authors discuss the implications of their findings for managerial action, as well as for researchers, and they propose directions for future research.

Purpose The purpose of this study is to examine regulatory sanctions from an emerging economy perspective and analyzing the impact of regulators imposed monetary sanctions on banks’ performance. Design/methodology/approach The study adopted correlational research design to examine the effect of regulatory penalties on the performance of deposit money banks in Nigeria. This study used panel data from a sample of 15 deposit money banks in Nigeria for the period of 2006-2015. Multiple regression analysis was carried out. Findings Results showed that penalties imposed by regulators in the Nigerian banking industry have no significant impact on the bottom line of the defaulters. Penalties imposed on foreign exchange and international trade related infraction showed that the cost of penalties is below the benefits enjoyed from such infractions. Practical implications The insignificant impact of penalties on performance implies that deposit money banks have considered penalties imposed by regulators as operational expenses and transferred such to customers. Originality/value The study differs from other studies that examined regulatory penalties on performance by focusing on financial performance and using data from an emerging economy perceived to have weak regulatory environment.

While there has been research into what teams, leagues, and athletes post on social media and the impact of post content on social media engagement, there is limited understanding and empirical research on the impact of broadcasting media on social sport consumption. There are an increasing number of new media through which sport leagues can distribute their content to fans. This research examines the impact of different broadcast platforms on game day engagement with WNBA team Twitter accounts. Using data for the 2016–2018 seasons, results indicate athlete/team quality and performance were positively associated with post engagement, underscoring the importance of the core sport product and potentially indicating that the WNBA is developing a star-driven culture similar to the NBA. In addition, broadcasting on League Pass or local TV (for home teams) and Twitter were associated with lower post engagement suggesting we have more to learn about maximizing online engagement.

This paper examines, using various econometric techniques, the impact of intellectual capital (IC) on the performance of Egyptian insurance companies listed between 2006 and 2011. We measure IC using the value added intellectual coefficient (VAIC) approach and its components developed by Pulic (2000), and both a direct and a moderating relationship between VAIC and corporate performance are investigated. Our results show a direct relationship between (IC-VAIC) and the performance of Egyptian insurance companies, particularly with capital employed efficiency (CEE), and to a lesser extent with human capital efficiency. In addition, a positive relationship between IC (capital employed and structural capital) and performance in the prior and current years is found. Evidence also suggests the possibility of a moderating relationship between IC and physical and financial capital, which in turn impacts on corporate performance. Our study also reveals the importance of taking into account any unobservable heterogeneity and endogeneity issues when analysing corporate performance.

Orientation: Corporate governance adoption and compliance are an issue augmenting in importance recently and have been extended to business enterprises of any size including small and medium enterprises (SMEs).Research purpose: This study seeks to examine the impact of corporate governance adoption on the firm competitiveness and performance of SMEs in Vanderbijlpark.Research design, approach and method: The study employs a cross-sectional research design, which employed quantitative methods. One hundred fifty-two SME owners or managers were selected from Vanderbijlpark in Gauteng, South Africa. The collected data were analysed using a structural equation modelling system by using Smart PLS software.Main findings: The principal findings of this study revealed that the implementation of corporate governance by SMEs significantly and positively affected their competitiveness and performance.Practical and managerial implications: The paper provided practical implications and made some recommendations.Contribution or value-added: This article bridges the gap between theory and practice because it has both an economic and commercial impact in practice. It can be used in influencing public policy, teaching and research (because it contributes to the body of knowledge, particularly regarding SME corporate governance in emerging markets). An important aspect of this article is that it gives a framework for additional similar studies in other locations within emerging markets to test the generalisability of the findings. For teaching purposes, it provides a template for how to assess the link that exists between corporate governance and SME performance. Lastly, the article gives a unique empirical analysis of the relationship that exists between corporate governance compliance and performance of firms in South Africa, and thereby giving a valid contribution to corporate governance literature.

New research on the behaviour and performance of over 200 fast-moving consumer businesses selling through multiple outlets show that: (i) the "economic case" for branding can be demonstrated — there is evidence that brands can help producers bring new products and services to market, and that they help consumers exercise effective choice of "value for money"; (ii) branded producers are more innovative than their non-branded counterparts; (iii) branded producers typically create significantly more value added from investment in innovation; and (iv) non-price competition is particularly strong in the branded sector, with the key drivers of growth for individual businesses being improving value position, innovation advantage and reputation. Branded product markets show these "rules" for business growth much more clearly than businesses in the economy as a whole. In branded businesses, we can identify the impact of investment in intangibles — communication and technology development — through the strengthening of capabilities, the building of intangible business assets in the form of reputation, innovative edge and value advantage. This comprises a model for innovation which is both statistically valid and endorsed by practising managers.

The Impact

The drivers of economic growth and development are among the most important issues explored by economic theory. Sustainability of economic development was previously linked by various economic schools of thought to natural resources (agriculture, land, minerals, metals etc.), labor force (including skills, productivity, and education), entrepreneurship or technology and innovation. Capital was later introduced by classical economic theory as the key element. Without significant capital accumulation, all other production factors remain idle. The value added of the production process is a result of the existence, the accessibility and the cost of capital. Therefore, the development and the sophistication of the financial sector has gradually become very important for any nation interested in sustainable growth. This paper investigates the impact of financial sector development, sophistication and performance on economic growth based on a panel regression methodology. We found statistically significant results that confirm the importance of this connection and that are very consistent with economic theory and previous relevant articles and studies.
