En este trabajo se investiga si la supervisión de la Comisión de Valores reduce la complejidad de los informes financieros. Para ello se utilizan las cartas de opinión (comment letters) de la Comisión de Valores de Irán. Además, para medir dicha complejidad, se emplea el índice de Fog. Usando un diseño de diferencia en diferencias con la aproximación propensity score matching, se encuentra que la supervisión de la Comisión de Valores reduce esta complejidad. Además, se muestra que el impacto de la supervisión de las comisiones de valores en la complejidad de los informes financieros es mayor para las empresas con mayor calidad de gobierno corporativo.  También se documenta que este impacto (1) no se limita a un año y persiste al menos dos años después, y (2) no es mayor para las empresas que reciben más cartas de opinión (comment letters). Además, se constata el efecto indirecto de la supervisión de la comisión de valores, en el sentido de que las empresas que no reciben ninguna carta de opinión (comment letters) reducen la complejidad de sus informes financieros si la comisión de valores ha hecho comentarios sobre la empresa líder del sector o sobre un competidor cercano. En definitiva, este artículo proporciona, por un lado, evidencia relacionada con el debate internacional sobre si las comisiones de valores podrían tener efectos beneficiosos en la información financiera que elaboran las empresas y, por otro, contribuye a la literatura sobre la complejidad de los informes financieros y los factores que reducen la misma, lo cual ocupa un lugar destacado entre los temas más importantes en el contexto de la información financiera internacional. We investigate whether securities commission oversight reduces the complexity of financial reporting (complexity). To measure the securities commission oversight, we use comment letters from securities commission of Iran. Further, to measure the complexity, we employ the Fog index. Using a difference-in-differences design with a propensity score matching approach, we find that the securities commission oversight reduces the complexity. Furthermore, we document that the impact of securities commission oversight on the complexity is stronger for firms with higher corporate governance quality.  In addition, we document that the impact of securities commission oversight on the complexity (1) is not limited to one year and persists through at least two years later; and (2) is not higher for firms that receive more comment letters. We further document the spillover effect of securities commission oversight, in the sense that firms not receiving any comment letter reduce their complexity if the securities commission has commented on the industry leader or a close rival. Collectively, this paper, on the one hand, provides related evidence for the international debate on whether securities commissions could provide beneficial effects; and on the other hand, contributes to the literature on the complexity and its reducing factors that are among the most important issues in the context of international financial reporting.

The Impact

Despite the undeniable advantages of innovative agricultural production technology, their adoption rate in Morocco is relatively low. In addition to research institutes and private institutions, agricultural information is provided by extension agents who are limited in terms of financial and logistical resources. In this study, we examine, on the one hand, the factors influencing the adoption of mobile phones to access extension services. On the other, we measure the impact of this adoption on wheat production and farmers’ income in the province of Settat (Morocco). In this study we use data collected through a survey of 130 farmers from the province of Settat (Morocco). As analysis methods, we use stratified sampling, descriptive statistics, and the propensity score matching model. The results revealed that farmers who use their mobile phones for extension purposes have slightly higher wheat production than those who do not. The developed model showed that the adoption of mobile phone-based extension services is influenced by farmer's age, educational level, primary source of income, the use of inorganic fertilizers, access to credit and the availability of road infrastructure. The study is a contribution to the efforts of various national stakeholders who have launched a national strategy focused on the digitalisation of extension services.

AbstractTerrestrial and aquatic ecosystems are increasingly threatened by pesticide pollution resulting from extensive use of pesticides, and due to the lack of regulatory measures in the developing world, there is a need for affordable means to lessen environmental effects. This study aimed to investigate the impact of biochar amendment on the toxicity of imidacloprid to life-cycle parameters and biomarker responses of the earthworm Eisenia fetida. E. fetida was exposed to 10% biochar-amended and non-amended OECD artificial soils spiked with 0, 0.75, 1.5, 2.25 and 3 mg imidacloprid/kg for 28 days. An LC50 of 2.7 mg/kg was only computed in the non-amended soil but not in the biochar-amended soil due to insignificant mortality. The EC50 calculated in the non-amended soil (0.92 mg/kg) for reproduction (fertility) was lower than the one computed in the biochar amended (0.98 mg/kg), indicating a decrease in toxicity in the biochar-amended substrate. Significant weight loss was observed at the two highest imidacloprid treatments in the non-amended soil and only at the highest treatment in the biochar-amended substrate, further highlighting the beneficial effects of biochar. Catalase activity decreased significantly at the two highest concentrations of non-amended soil. Yet, in the amended soil, the activity remained high, especially in the highest concentration, where it was significantly higher than the controls. This indicated more severe oxidative stress in the absence of biochar. In all non-amended treatments, there was a significant acetylcholinesterase inhibition, while lower inhibition percentages were observed in the biochar-amended soil. In most endpoints, the addition of biochar alleviated the toxic effects of imidacloprid, which shows that biochar has the potential to be useful in soil remediation. However, there is still a need for field studies to identify the most effective application rate of biochar for land application.

Few papers discuss how the economic burden of patients with stroke receiving rehabilitation courses is related to post-acute care (PAC) programs. This is the first study to explore the economic burden of stroke patients receiving PAC rehabilitation and to evaluate the impact of multidisciplinary PAC programs on cost and functional status simultaneously. A total of 910 patients with stroke between March 2014 and October 2018 were separated into a PAC group (at two medical centers) and a non-PAC group (at three regional hospitals and one district hospital) by using propensity score matching (1:1). A cost–illness approach was employed to identify the cost categories for analysis in this study according to various perspectives. Total direct medical cost in the per-diem-based PAC cohort was statistically lower than that in the fee-for-service-based non-PAC cohort (p < 0.001) and annual per-patient economic burden of stroke patients receiving PAC rehabilitation is approximately US $354.3 million (in 2019, NT $30.5 = US $1). Additionally, the PAC cohort had statistical improvement in functional status vis-à-vis the non-PAC cohort and total score of each functional status before rehabilitation and was also statistically significant with its total score after one-year rehabilitation training (p < 0.001). Early stroke rehabilitation is important for restoring health, confidence, and safe-care abilities in these patients. Compared to the current stroke rehabilitation system, PAC rehabilitation shortened the waiting time for transfer to the rehabilitation ward and it was indicated as an efficient policy for treatment of stroke in saving medical cost and improving functional status.

Abstract Background Adoption of improved agricultural technologies remains to be a promising strategy to achieve food security and poverty reduction in many developing countries. However, there are limited rigorous impact evaluations on the contributions of such technologies on household welfare. This paper investigates the impact of improved agricultural technology use on farm household income in eastern Ethiopia. Methods Primary data for the study was obtained from a random sample of 248 rural households, 119 of which are improved technology users and the rest are non-users. The research employed the Propensity Score Matching (PSM) procedure to establish the causal relationship between adoption of improved crop and livestock technologies and changes in farm income. Results Results from the econometric analysis show that households using improved agricultural technologies had, on average, 23,031.28 Birr (Birr is the official currency of Ethiopia. The exchange rate according to the National Bank of Ethiopia (NBE) was 1 USD = 27.6017 Birr on 04 October 2018.) higher annual farm income compared to those households not using such technologies. Our findings highlight the importance of promoting multiple and complementary agricultural technologies among rural smallholders. Conclusions We suggest that rural technology generation, dissemination and adoption interventions be strengthened. Moreover, the linkage among research, extension, universities and farmers needs to be enhanced through facilitating a multistakeholders innovation platforms.

Introduction: Current evidence suggests that dual antiplatelet therapy (DAPT) reduces perioperative stroke, but increases bleeding after carotid endarterectomy (CEA). The long term effects of antiplatelet therapy after CEA have yet to be studied. Methods: A retrospective review of patients undergoing CEA in the national Vascular Quality Initiative database (2003-2018) was performed. Based on antiplatelet regimen at discharge, patients were propensity score matched on aspirin monotherapy vs. DAPT. Multivariable logistic regression and Kaplan-Meier analyses were used to investigate the long term effects of antiplatelet regimen on mortality and stroke/TIA. Results: Of the 72,122 patients undergoing CEA, 64.6% were discharged on aspirin, and 35.4% on DAPT. The DAPT group had higher frequencies of comorbidities (COPD, HTN, CHF, smoking, diabetes) as well as atherosclerotic diseases (PAD, CAD, prior PCI, prior CABG). After propensity score matching, two groups of 8,722 patients with comparable comorbidities were formed. While unmatched Kaplan-Meier analysis showed the DAPT cohort to have higher mortality (p=0.001), this difference dissipated after matching. The resultant matched DAPT cohort did not differ from the aspirin group in one year stroke/TIA (1.7% vs. 1.6%, p=0.70), or mortality (3.1% vs. 3.3%, p=0.55). At 5 years, however, patients treated with DAPT did exhibit a mortality benefit (6.4% vs. 7.3%, p=0.02) with multivariable logistic regression identifying DAPT as an independent predictor of reduced mortality (OR 0.94, 95% CI 0.88-0.99, p=0.04). Conclusions: Patients discharged on DAPT after CEA represent a significantly different cohort than those discharged on aspirin monotherapy. After propensity score matching, there was no difference at one year stroke/TIA or mortality outcomes, but DAPT was found to be protective against long-term mortality. Further study is warranted to investigate this finding.

The Impact

This contribution scrutinises how introducing a statutory minimum wage of EUR 8.50 per hour, in January 2015, impacted German employees’ decision with regard to union membership. Based on representative data from the Labour Market and Social Security panel, the study applies a logistic difference-in-differences propensity score matching approach on entries into and withdrawals from unions in the German Trade Union Confederation (Deutscher Gewerkschaftsbund, DGB). The results show no separate effect on withdrawals from or entries into unions after the minimum wage introduction for those employees who benefited financially from it, but a significant increase of entries overall. Thus, unions’ campaign for a minimum wage strengthened their position in total but did not reverse the segmentation of union membership patterns.

<p><strong>Abstract:</strong></p><p>This study estimates the impact value of the VietGAP program when applied to vegetable production on the health of farmers in Thua Thien Hue province. By employing the propensity score matching (PSM) method, our findings show that the VietGAP program has a significant impact on farmers’ health. In particular, the program reduces farmers’ health problems due to pesticide exposure by 15.6 %, 22.9 %, 25.5 %, and 23.6 %, respectively, from four types of matching. This study provides evidence of the positive impacts of the VietGAP program on the health status of farmers in Thua Thien Hue province. It is therefore hoped that the production, consumption, and management solutions provided by the VietGAP program can encourage farmers to use environment-friendly agricultural practices.</p><p><strong>Keywords: </strong>propensity score matching (PSM) method, VietGAP program, farmers’ health</p>
