Title: The impact of an increase in foreigners on the waiting times in healthcare in Malta Abstract: The increasing presence of foreign residents in Malta has raised questions about its impact on essential public services, including healthcare. As Malta’s only major public hospital, Mater Dei Hospital’s Emergency Department (ED) is critical to meeting the healthcare needs of both locals and foreigners. With the continuous growth of the foreign population, concerns have emerged regarding potential strains on the system, particularly in terms of increased waiting times in emergency care. This study investigates the impact of foreign residents on waiting times in Malta’s healthcare system, specifically at Mater Dei Hospital’s Emergency Department (ED). The objective is to assess whether foreign residents experience longer waiting times than Maltese residents and to identify the main factors contributing to these delays. Using data spanning from 2017 to 2023, the research employs an Ordinary Least Squares (OLS) regression model to examine various determinants of ED waiting times, including nationality, age, gender, arrival type, triage level, and the need for admission. The methodology involved comprehensive data cleaning and preparation of over 600,000 anonymous observations from Mater Dei’s records to fully adhere to ethical considerations. Separate regressions were run for the years 2017, 2020, and 2023 to account for temporal variations, particularly the effects of the COVID-19 pandemic. The results showed that although nationality has a statistically significant impact on waiting times, its influence is relatively low compared to other variables. These findings underscore the need for policy measures to manage ED demand, particularly for non-native populations, and improve the overall efficiency of Malta’s healthcare system.

Title: The impact that trade unions exert on the gender pay gap : evidence from a panel of European countries Abstract: Governments and supranational organisations around the globe have placed a strong emphasis on addressing the Gender Pay Gap. As a result, various policies have been put into action in recent years to tackle this problem, and it remains a central focus in numerous policy discussions and agendas. The objective of this dissertation is to explore whether the participation of trade unions contribute to reducing this disparity. To arrive at a conclusion, the Fixed-Effects Model is employed, for a sample of nineteen European countries spanning a period of ten years from 2009 to 2018. The results obtained provide contradictory results as found in the existing literature. When running the model without incorporating fixed-effects, this study concludes that trade unions contribute to reducing the gap, which aligns with the majority of the literature consulted. However, when fixed-effects were included in the model, mixed results emerged. This is because when using both country and year fixed-effects the result was positive and insignificant. Moreover, when including solely country fixed-effects the coefficient on the trade union density rate while still positive, shows that it has a statistically significant relationship with the dependent variable, the gender pay gap. In addition, the same result as when the model was run without fixed-effects was also established when only year fixed-effects were included, since a negative statistically significant relationship was established.

Title: Estimating the potential economic benefits of applying overseas substance abuse prevention programs in Malta Abstract: This study presents a detailed Cost-Benefit Analysis of introducing new substance abuse prevention initiatives in Malta. The proposed initiatives aim to extend the availability of schools beyond regular hours to provide safe environments for adolescents and reduce the intervals between data collection to support timely policy updates. Utilizing a mixed-method approach, the research combines primary data from contingent valuation surveys to estimate willingness-to-pay for benefit evaluation and secondary data from expert opinions, international studies, and local sources. The primary aim is to assess the cost-effectiveness of this initiative, focusing on adolescents and comparing scenarios with and without its implementation. The analysis includes four scenarios: a scenario for tobacco use reduction, alcohol use reduction, illicit drug use reduction, and a combined scenario of all three. Employing a cost-benefit approach and the Benefit Transfer Method, both direct and indirect benefits and costs are estimated. Key findings indicate significant economic viability, with a positive net present value and a benefit-cost ratio greater than 1. The combined scenario yields an NPV of €44.35 million and a BCR of 8.09, highlighting the substantial benefits of the prevention program relative to its costs. Sensitivity analysis highlights the robustness of these results, showing positive returns even under less favourable conditions. This study emphasizes the importance of continued and expanded substance use prevention efforts, recommending the integration of these initiatives into broader, multi-component prevention strategies to optimize their impact on public health and economic outcomes in Malta.

Title: An investigation of the relationship between inflation and unemployment in selected Eurozone countries Abstract: Two main issues that are of priority to policymakers are those of inflation and unemployment, and economists have long carried out research as to whether a relationship exists between these two variables. A.W. Phillips discovered that the UK had a negative relationship between inflation and unemployment during the period 1861 to 1957, as an increase in the inflation rate led to a fall in unemployment. This dissertation investigates the relationship between inflation and unemployment for a sample of 6 countries - Cyprus, Latvia, Lithuania, Malta, Slovakia, and Slovenia. These countries all joined the European Union in 2004, and then over time also went on to adopt the Euro currency. Data for the period from 2004, which was the year each country joined the EU, until 2022 on a quarterly basis is used and analysed through OLS regression before and after Euro adoption. In addition, a multivariate regression is carried out for each country to investigate the effect of two other important economic markers, interest rates and unit labour costs, together with inflation, on unemployment. Finally, a Vector Autoregression was carried out in order to also consider the effect of previous values of the same variables. Results confirmed the anticipated negative relationship between inflation and unemployment in each of the selected countries. However, this relationship varies in magnitude depending on the country concerned. When looking at the multivariate regression, relationship signs with all variables are also as anticipated. This is evident in the OLS and multivariate regression models, in particular after Euro adoption, indicating that the economic policies required for Euro adoption have a similar effect in the different countries, albeit at different levels of strength and significance.
