    This study examines the effects of news events related to the European Union-Vietnam Free Trade Agreement (EVFTA) on the Vietnam stock market from 2010 to 2020. We calculate sectoral abnormal returns prior to, during, and after announcements and find that the Vietnamese stock market is susceptible to these events. We discovered that the announcement had a negative impact on the market, which might diminish the effectiveness of the Agreement. The findings show that more than half of Vietnam's sectors had an immediate reaction to EVFTA announcements, with fourteen reacting negatively and six responding positively. Two of the ten events did not have any immediate impact on these industries but all events resulted in either early or delayed reactions. We also find market scepticism and major changes in the deal led to the emergence of a diamond risk structure. We run multiple robustness tests to account for market integration and other factors that may affect stock returns. In addition, we explore potential sectoral systematic risk changes following these occurrences using different ARCH-type models. These additional tests confirm the robustness of our findings

    Lactobacillaceae and Cell Adhesion: Genomic and Functional Screening

    The analysis of collections of lactic acid bacteria (LAB) from traditional fermented plant foods in tropical countries may enable the detection of LAB with interesting properties. Binding capacity is often the main criterion used to investigate the probiotic characteristics of bacteria. In this study, we focused on a collection of 163 Lactobacillaceace comprising 156 bacteria isolated from traditional amylaceous fermented foods and seven strains taken from a collection and used as controls. The collection had a series of analyses to assess binding potential for the selection of new probiotic candidates. The presence/absence of 14 genes involved in binding to the gastrointestinal tract was assessed. This enabled the detection of all the housekeeping genes (ef-Tu, eno, gap, groEl and srtA) in the entire collection, of some of the other genes (apf, cnb, fpbA, mapA, mub) in 86% to 100% of LAB, and of the other genes (cbsA, gtf, msa, slpA) in 0% to 8% of LAB. Most of the bacteria isolated from traditional fermented foods exhibited a genetic profile favorable for their binding to the gastrointestinal tract. We selected 30 strains with different genetic profiles to test their binding ability to non-mucus (HT29) and mucus secreting (HT29-MTX) cell lines as well as their ability to degrade mucus. Assays on both lines revealed high variability in binding properties among the LAB, depending on the cell model used. Finally, we investigated if their binding ability was linked to tighter cross-talk between bacteria and eukaryotic cells by measuring the expression of bacterial genes and of the eukaryotic MUC2 gene. Results showed that wild LAB from tropical amylaceous fermented food had a much higher binding capacity than the two LAB currently known to be probiotics. However their adhesion was not linked to any particular genetic equipment

    Prevalence of Frailty in European Emergency Departments (FEED): an international flash mob study

    Introduction Current emergency care systems are not optimized to respond to multiple and complex problems associated with frailty. Services may require reconfiguration to effectively deliver comprehensive frailty care, yet its prevalence and variation are poorly understood. This study primarily determined the prevalence of frailty among older people attending emergency care. Methods This cross-sectional study used a flash mob approach to collect observational European emergency care data over a 24-h period (04 July 2023). Sites were identified through the European Task Force for Geriatric Emergency Medicine collaboration and social media. Data were collected for all individuals aged 65 + who attended emergency care, and for all adults aged 18 + at a subset of sites. Variables included demographics, Clinical Frailty Scale (CFS), vital signs, and disposition. European and national frailty prevalence was determined with proportions with each CFS level and with dichotomized CFS 5 + (mild or more severe frailty). Results Sixty-two sites in fourteen European countries recruited five thousand seven hundred eighty-five individuals. 40% of 3479 older people had at least mild frailty, with countries ranging from 26 to 51%. They had median age 77 (IQR, 13) years and 53% were female. Across 22 sites observing all adult attenders, older people living with frailty comprised 14%. Conclusion 40% of older people using European emergency care had CFS 5 + . Frailty prevalence varied widely among European care systems. These differences likely reflected entrance selection and provide windows of opportunity for system configuration and workforce planning

    The financial consequences of abolishing a carbon trading system

    No full text
    We investigate the impact of 61 announcements of environmental regulations on the equities listed on the Australian Stock Exchange over the period 2009-2015. In particular, our study focuses on how the stock market reacts to announcements of the abolishment of carbon trading/pricing system. Using event study methodology, we assess whether these announcements create or destroy wealth of equity investors. Furthermore, we estimate changes in systematic risk following the announcements. In general, we find that the abolishment of the carbon pricing system has a positive effect on 18 sectors and the process of removing the carbon pricing system appears to affect the systematic risk of businesses leading to diamond risk structures. We also document negative reactions of polluting sectors to the announcements of green policies

    The effects of regulatory announcements on risk and return: the Vietnamese experience

    No full text
    Purpose - The purpose of this paper is to test the effects of financial regulatory announcements on risk and return in the Vietnamese equity market. Design/methodology/approach - The event study methodology is used for the return analysis, and asset pricing models are adjusted for the risk analysis. Various robustness tests are used, including the Corrado non-parametric ranking test and the Chesney et al. non-parametric conditional distribution test, as well as GARCH, TARCH, EGARCH and PARCH specifications for the risk models. Findings - The authors find evidence for both negative and positive reactions as well as risk shifting behaviour in the form of a diamond risk structure. Originality/value - This paper fills a major gap in the literature by investigating the market's reaction to bank regulatory announcements across financial and non-financial sectors in the Vietnamese equity market

    The effects of the Paris climate agreement on stock markets: evidence from the German stock market

    No full text
    We investigate the effects of the 2016 Paris Climate Agreement on the German stock market by considering the impact of 20 announcements pertaining to the Agreement on 17 industries. The event study methodology is used for this purpose, together with several robustness tests, such as the nonparametric rank test and non-parametric conditional distribution approach. The change in systematic risk following the announcements is captured by using various risk models. In general, we find that the Paris Climate Agreement is achieving its objectives in the short run. Our results show that the announcements affected polluting industries in terms of risk and return. Furthermore, we observe two distinct diamond risk structures when (1) Conference of the Parties(COP)21 took place, and (2) the Agreement came into force

    The financial effects of Trumpism

    This paper investigates the effects of the 2016 US presidential election, and the events occurring in the run-up to election day, on the US stock market. We examine 47 events, starting with Donald Trump's announcement that he would contest the presidential election, using the event study methodology and asset pricing models. Furthermore, we conduct several robustness tests, including the Corrado ranking test, the non-parametric conditional distribution approach, adjustment for market integration, the removal of firms with firm-specific news, and the use of more than one asset pricing model. We observe that the US stock market was affected by the 2016 presidential election and that the US stock market was highly responsive when Trump secured the Republican nomination. The life insurance sector was one of the most negatively affected sectors due to Trump's intention to replace Obamacare. In addition, our results show that the events around the most recent election can lead to diamond risk structures
