AbstractThis paper examines the impact of a policy reform in a municipality in Norway that extended to workers the right to self-certify sickness absence from work. After the reform, workers were no longer obliged to obtain a certificate from a physician to receive sickness benefits. They could call in sick directly to their line leader and had to engage in a counselling program organized by the employer. To estimate the effect of this reform, we contrast the change in sickness absence among employees who were granted the extended right to self-certify absence with absence among employees who had to obtain a physician’s certificate to be entitled to sickness benefits. We use both a standard difference-in-differences method and the synthetic control method to estimate the effect of the reform. We can rule out large positive effects on absence after the reform, with strong evidence that the policy change actually resulted in a reduction in absence for female workers.

The availability of attractive complementary products offered by a nearby company positively affects other companies in the value network of a winter sports destination. We aim to illustrate empirically the positive effects of the campaign of a local ski lift company in Switzerland on other companies in the same value network. For the first time in tourism research, the synthetic control method is used to investigate the impact of a new pricing strategy. In this case, the company’s practice of radically discounting the prices of its seasonal lift passes had a positive impact on accommodation businesses in the same winter sports destination. The impact amounts to about 35% additional overnight stays by domestic tourists per winter season that is a seasonal increase of 32,000 overnight stays. However, the ski lift company concluded that the campaign had been unsuccessful. We therefore discuss the difficulties of such a new pricing strategy and emphasize the importance of cooperation between independent companies in the wider destination area.

Control Of Corruption

In 2014, the most prominent anti-corruption investigation in Latin America called Lava Jato, exposed a Brazilian corruption scheme with reverberations in 61 countries, resulting in legal judgments for nearly 5 billion USD in reimbursements thus far. This article applies the synthetic control method on data from 135 countries (2002–2018) to test the hypothesis that Lava Jato impacts the Worldwide Governance Indicators in Brazil. The findings reveal that Lava Jato negatively affects control of corruption, the rule of law, and regulatory quality. There are signs of possible improvement in at least the corruption and the rule of law measures. This paper brings value to the criminological body of literature, notably lacking in the Global South.

AbstractIn some applications, researchers using the synthetic control method (SCM) to evaluate the effect of a policy may struggle to determine whether they have identified a “good match” between the control group and treated group. In this paper, we demonstrate the utility of the mean and maximum Absolute Standardized Mean Difference (ASMD) as a test of balance between a synthetic control unit and treated unit, and provide guidance on what constitutes a poor fit when using a synthetic control. We explore and compare other potential metrics using a simulation study. We provide an application of our proposed balance metric to the 2013 Los Angeles (LA) Firearm Study [9]. Using Uniform Crime Report data, we apply the SCM to obtain a counterfactual for the LA firearm-related crime rate based on a weighted combination of control units in a donor pool of cities. We use this counterfactual to estimate the effect of the LA Firearm Study intervention and explore the impact of changing the donor pool and pre-intervention duration period on resulting matches and estimated effects. We demonstrate how decision-making about the quality of a synthetic control can be improved by using ASMD. The mean and max ASMD clearly differentiate between poor matches and good matches. Researchers need better guidance on what is a meaningful imbalance between synthetic control and treated groups. In addition to the use of gap plots, the proposed balance metric can provide an objective way of determining fit.

This study aimed to assess current evidence regarding the effect of selenium (Se) supplementation on the prognosis in patients sustaining trauma. MEDLINE, Embase, and Web of Science databases were searched with the following terms: “trace element”, “selenium”, “copper”, “zinc”, “injury”, and “trauma”. Seven studies were included in the meta-analysis. The pooled results showed that Se supplementation was associated with a lower mortality rate (OR 0.733, 95% CI: 0.586, 0.918, p = 0.007; heterogeneity, I2 = 0%). Regarding the incidence of infectious complications, there was no statistically significant benefit after analyzing the four studies (OR 0.942, 95% CI: 0.695, 1.277, p = 0.702; heterogeneity, I2 = 14.343%). The patients with Se supplementation had a reduced ICU length of stay (standard difference in means (SMD): −0.324, 95% CI: −0.382, −0.265, p < 0.001; heterogeneity, I2 = 0%) and lesser hospital length of stay (SMD: −0.243, 95% CI: −0.474, −0.012, p < 0.001; heterogeneity, I2 = 45.496%). Se supplementation after trauma confers positive effects in decreasing the mortality and length of ICU and hospital stay.

Amendment to the United Nations Convention on the Law of the Sea of 1982 with Law No. 17 the Year 1985 makes Indonesia have the right to utilize, conservation, and manage fish resources in Indonesia's exclusive economic zone and the high seas. Such rights are exercised under applicable international terms or standards. Therefore, legislation was made related to the sinking of illegal fishing vessels in Indonesian territorial waters through Law No. 45 of 2009 on Fisheries. Indonesia's high wealth of marine resources does not run following all layers' expectations after illegal fishing. However, the juridical consequences of applying the law have several impacts, namely the impact of sinking foreign vessels on relations with foreign countries and negative-positive effects in the marine environment due to the sinking of foreign vessels illegal fishing actors.

The purpose of the research is to assess the impact of the action plan of the Employment Roadmap on the unemployment rate in Kazakhstan.Methodology. Synthetic Control Method was used in this paper. The method, which compares one or more units exposed to the event and determines what would have happened if the unit had not been treated. In other words, this method creates a weighted combination of control states to create a single «synthetic» control group, in order to approach the counterfactual unit in Kazakhstan in the absence of a plan or Roadmap.The originality / value of the research based on the analysis, panel data from Kazakhstan and 13 donor pool countries for the period 2000-2019 were taken for modeling.Findings: As a result of the study, it was revealed that the unemployment rate would have been 2% higher in 2019 if Kazakhstan had not adopted an action plan in the form of an Employment Roadmap in 2009.
