Internet use and agricultural productivity in rural Vietnam

The use of the internet is growing rapidly and has become an engine for economic development. However, few studies have examined the impact of internet use on agricultural production, and the results are not yet conclusive. Employing a dataset of more than 2000 observations in rural Vietnam, our study analyses the impact of internet use on agricultural productivity using the heteroscedasticity-based instrument approach suggested by Lewbel, Journal of Business and Economic Statistics, 2012, 30, 67–80 and examines the heterogeneity and distribution of the impact using quantile regressions. Our results show that internet use has significant and positive effects on agricultural productivity. However, these effects are heterogeneous across population groups. The positive effects of internet use are stronger for households with a lower level of education, with a young and female head, and from ethnic minorities. The benefits are also found to be skewed towards the group of farmers at the bottom of the productivity distribution. Therefore, we propose facilitating the diffusion of the internet, since it not only boosts agricultural productivity, but also reduces productivity inequality. In addition, we recommend promoting rural education, supporting local markets, investing more in irrigation systems, and facilitating farm mechanisation as these factors are found to contribute to increasing agricultural productivity.     

Investor reactions to key audit matters: Financial and non-financial contexts

We investigate how a disclosed risk item and key audit matter (KAM) relatedness combine to affect investors' riskiness assessment in financial and non-financial contexts. When management disclose a high-risk item, we find that investors react the same way across contexts with KAM relatedness having no effect. When management disclose a low-risk item, investors react differently in each context. When a KAM is related to the disclosed financial (non-financial) low-risk item, investors assess investment riskiness higher (lower) than when a KAM is unrelated to the low-risk item. Our findings indicate the varying communicative value of KAMs across financial and non-financial contexts.     

Trade and employment in Vietnam: how firms' trade matters

This paper aims to analyse how employment and wages change when a firm's trade status is altered. Using a detailed firm-level dataset of Vietnamese manufacturing enterprises, the study finds that how firms trade matters for firm employment and wages in Vietnam. The average effect of one-way trading (exporting or importing) is positive for both firms' total employment and female employment. Direct trading activities are associated with a higher level of employment than indirect trading activities by firms. The female employment effect of direct exports is nearly three times higher than direct imports. Indirect imports hurt firms' total employment and female employment. Both direct and indirect two-way traders experience higher growth in firm employment than direct-only traders. However, it is interesting to note that indirect two-way trading activities have a positive impact on female employment. Furthermore, the commencement of direct import is also associated with greater labour cost advantage.
