Real and Accrual‐Based Earnings Management in the Pre‐ and Post‐IFRS Periods: Evidence from China

The purpose of this study is to investigate the prevalence of both accrual‐ and activities‐based earnings management for Chinese A‐share firms surrounding the adoption of substantially IFRS‐convergent accounting standards. Since 2007, all listed A‐share firms in China have been required to comply with a new set of accounting standards that have substantially conformed to IFRS. The new reform also produced a set of new auditing standards and internal control reporting requirements. Based on a sample of 4,050 firm‐year observations from 2002 to 2011, we find that Chinese firms in the post‐IFRS period (2007–2011) are less likely to engage in accrual‐based earnings management. The magnitude of discretionary accruals also declines after IFRS adoption. In response, we see firms turning to real activities manipulation as a substitute for upward earnings management. The reduction in accrual‐based earnings management could stem from higher quality accounting standards associated with IFRS adoption and/or concurrent changes in the governance regimes introduced with the IFRS mandate. A further analysis, however, indicates that the benefits of IFRS adoption in curbing upward accrual‐based earnings manipulation are not evenly distributed across firms. Specifically, the benefit diminishes for firms that are controlled by Chinese central or local governments, are located in less developed regions, and that have weak financial performance and therefore subject to delisting status. We also find that the benefit is less pronounced for manufacturing firms than for their non‐manufacturing counterparts.     

On the Determinants of School District Efficiency: Competition and Monitoring

A number of researchers have asserted that inefficiency in the U.S. school system arises from a lack of incentives for public schools to behave efficiently. This paper uses a Shephard input distance function to model educational production, and a switching-regressions estimation to explore the relationship between school district efficiency and two existing incentive mechanisms—competition and voter monitoring. We find evidence that ease of monitoring enhances both technical and allocative efficiency of urban school districts, and that increased competition reduces allocative inefficiency in communities above a competitive threshold. We find no evidence that competition is related to technical inefficiency.     

A Comparison of Sequential and Information‐based Methods for Determining the Co‐integration Rank in Heteroskedastic VAR Models

In this article, we investigate the behaviour of a number of methods for estimating the co‐integration rank in VAR systems characterized by heteroskedastic innovation processes. In particular, we compare the efficacy of the most widely used information criteria, such as Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) , with the commonly used sequential approach of Johansen [Likelihood‐based Inference in Cointegrated Vector Autoregressive Models (1996)] based around the use of either asymptotic or wild bootstrap‐based likelihood ratio type tests. Complementing recent work done for the latter in Cavaliere, Rahbek and Taylor [Econometric Reviews (2014) forthcoming], we establish the asymptotic properties of the procedures based on information criteria in the presence of heteroskedasticity (conditional or unconditional) of a quite general and unknown form. The relative finite‐sample properties of the different methods are investigated by means of a Monte Carlo simulation study. For the simulation DGPs considered in the analysis, we find that the BIC‐based procedure and the bootstrap sequential test procedure deliver the best overall performance in terms of their frequency of selecting the correct co‐integration rank across different values of the co‐integration rank, sample size, stationary dynamics and models of heteroskedasticity. Of these, the wild bootstrap procedure is perhaps the more reliable overall as it avoids a significant tendency seen in the BIC‐based method to over‐estimate the co‐integration rank in relatively small sample sizes.     

Working with community health workers to improve nutrition in rural KwaZulu-Natal

Addressing the health problems of disadvantaged communities requires innovative strategies in a situation of resource constraints. A community-based participatory intervention was undertaken in southern KwaZulu-Natal, using 18 local community health workers (CHWs). A baseline survey was conducted by each CHW, who visited five households to investigate factors affecting nutrition. After a training programme of monthly nutrition workshops, CHWs shared this information with local community members by visiting households and holding community meetings. After six months, a second questionnaire administered by CHWs investigated householder perceptions of the intervention. Data from the initial survey served as a basis for the content of the nutrition intervention by CHWs to improve health by influencing dietary practices. Factors affecting nutrition that were investigated included dietary practices, breastfeeding, sanitation, source of water and food gardens. CHWs learnt from this nutrition intervention and spread this information among their communities, suggesting a useful role for CHWs in implementing health-promoting initiatives.     

CAN THE POOR COUNTRIES CATCH UP? MIXED RESULTS FROM EXTENDED SOURCES OF GROWTH PROJECTIONS FOR THE EARLY 21st CENTURY

Illustrative projections of per capita income gaps between two groups of developing economies and the rich economies for the period 1998–2030 are made on the basis of an extended sources of growth equation which accounts for interactions between trends in capital and labor productivity. The equation takes into consideration Kaldor–Verdoorn effects, possible impacts on labor productivity of trade liberalization and/or astute industrial policy, human and physical capital accumulation, employment and population growth, shifting shares of labor in income and traded goods in output, shifts in capital productivity, productivity growth retardation due to convergence and specific regional effects. Under optimistic assumptions about all these factors and in the historically unprecedented absence of adverse macroeconomic shocks over three decades, relative and absolute convergence of both regions to the rich countries may be possible.     

What is SMS advertising and why do multinationals adopt it? Answers from an empirical study in European markets

This study examines the factors associated with the intention of multinational corporations operating in Europe to implement SMS advertising. It hypothesizes that managerial intentions to use this medium are related to the perceptions of four factors: (1) the ability to build brand image; (2) the ability to use location-based marketing; (3) the perceptions of how well consumers accept SMS advertising; and (4) the perceptions of the technological infrastructure. Results support the notion that managers from the European Union, Japan, and the United States will be more likely to adopt SMS advertising if they perceive it has the ability to help build the brand. They are also likely to perceive information security as a threat to the ability to “push” the product through the wireless channel. Results also suggest that managers give significant weight to the penetration of the technological infrastructure needed to run the ads through SMS-based messaging service.     

The Euro and European financial market dependence

A time-varying copula model is used to investigate the impact of the introduction of the Euro on the dependence between 17 European stock markets during the period 1994–2003. The model is implemented with a GJR-GARCH-MA-t model for the marginal distributions and the Gaussian copula for the joint distribution, which allows capturing time-varying, non-linear relationships. The results show that, within the Euro area, market dependence increased after the introduction of the common currency only for large equity markets, such as in France, Germany, Italy, the Netherlands and Spain. Structural break tests indicate that the increase in financial market dependence started around the beginning of 1998 when Euro membership was determined and the relevant information was announced. The UK and Sweden, but not other European countries outside the Euro area, are found to exhibit an increase in equity market co-movement, which is consistent with the interpretation that these countries may be expected to join the Euro in the future.     

Regulatory Uncertainty and the Volatility of Regional Electricity Company Share Prices: The Economic Consequences of Professor Littlechild

This paper attempts to measure the effects of regulatory intervention by measuring the conditional variance of stock price changes in the 12 UK regional electricity companies before and after an unexpected intervention by the electricity regulator in March 1995. The analysis uses an ARCH model in which the conditional variance follows an autoregressive formation. The results indicate a significant increase in the volatility of the conditional variance for eight of the 12 companies.
