Förvaltningsfastigheter värderas ofta till verkligt värde. Under en lång tid har värdering till verkligt värde varit något svårdefinierat, där begreppet haft olika betydelse i olika sammanhang. IFRS 13 uppkom till viss del med anledning av detta. Syftet med denna uppsats är att undersöka om IFRS 13 har påverkat underprissättningen för fastighetsföretag vid börsintroduktioner. Genom en Difference-in-Differences metod baserad på en uni- och en multivariat modell mäter vi det statistiska sambandet mellan IFRS 13 och underprissättning mellan åren 2005-2022 vid börsnotering av företag i fastighetsbranchen. Behandlingsgruppen består av länder inom Europeiska Unionen samt Norge, då dessa efterföljer IFRS som redovisningsstandard. Kontrollgruppen består av nio länder som inte har IFRS som obligatorisk redovisningsstandard. Resultatet visar på en negativ trend mellan underprissättningen och införandet av IFRS 13, men kan inte på ett statistiskt signifikant sätt fastställas. Resultatet visar dock ett negativt statistiskt signifikant samband på 0.1 procent mellan kapitalintäkten från börsintroduktionen och underprissättning samt ett statistiskt signifikant samband på 0.1 procent mellan Post och underprissättning för två av våra regressioner.

This thesis aims to examine the economic effect in terms of real GDP at constant 2017 national prices (in mil. 2017 US$) of being a member in the European Union in the case of Sweden. The method used to answer the research question is mainly by the Synthetic Control Method. Difference-in-difference estimations were also conducted as a complement to compare the results between the two methods. Previous literature in the subject has for the most part received results indicating that a membership in the European Union contributes to an increase in certain economic growth aspects for the member countries. The economic theories about common markets points at that a common market can be both advantageous but also disadvantageous depending on the setting. Theories more closely related to the European Union present rather ambiguous answers to certain economic effects of a membership but in some cases, it seems to be possible to assume some positive economic effect from being a European Union-member. The results in this paper seem to be robust in the way that the effect on the real GDP at constant 2017 national prices (in mil. 2017 US$) in Sweden from its membership in the European Union is negative in all estimations that were made. However, none of the results were statistically significant so there is not enough evidence to say that the Swedish real GDP at constant 2017 national prices (in mil. 2017 US$) would have been different to the factual outcome if Sweden did not join the European Union in 1995.

2024 / This thesis empirically evaluates the impact of voluntary minimum wage changes to firm reputation using data from the hiring website Indeed.com. As a starting point, I show that when Target and Amazon unilaterally raised their minimum wages, their ratings on Indeed.com improved substantially across multiple dimensions: work-life balance, compensation, job security, management, and culture. Next, I examine the impact of a focal firm voluntarily raising its minimum wage on the ratings of similar firms in proximal locations. Using a differences-in-differences (DiD) design, I present preliminary evidence that competitors that are located near the focal firm may expe- rience a negative reputational shock relative to similar firms that are geographically distant. Additionally, this thesis applies novel sentiment analysis techniques to eval- uate minimum wage policies on review text. Using state-of-the-art NLP models such as Claude, ChatGPT, and RoBERTa, I identify and score two topics that are im- portant to job reviewers, but do not receive star ratings on Indeed.com: ”Scheduling and Hours,” and ”Workload and Compensation.” Finally, I use LLMs to perform zero-shot fine-grained sentiment analysis to investigate how a company’s reputation in regards to these topics is impacted by voluntary minimum wage policies. In these analyses, I am not able to refute the null hypothesis, though the method demostrates promise for further development.

C’est grâce à une initiative de Revenu Québec, avec la collaboration de l’Association des restaurateurs du Québec, que le module d'enregistrement des ventes a été déployé dans le secteur de la restauration, entre le 1er septembre 2010 et le 1er novembre 2011, afin de lutter contre l’évasion fiscale. Jusqu’à ce jour, l’impact de ce projet a seulement été évalué à l’interne par Revenu Québec. Cette étude propose donc une analyse empirique, avec les données publiques canadiennes, afin d’évaluer l’impact de l’implantation du module d'enregistrement des ventes dans le secteur de la restauration au Québec, à l’aide d’un modèle en difference-in-differences et d’un modèle en Premières différences. Plus précisément, nous cherchons à déterminer si la mesure a eu un impact sur le PIB du secteur de l’hébergement et des services de restauration au Québec. Avec l’implantation du module d’enregistrement des ventes, on s’attend à ce que les possibilités d’évasion fiscale soient réduites et que les ventes déclarées augmentent. Les résultats de l’analyse suggèrent des signes potentiels d’effets de la mesure, sans toutefois avoir suffisamment de précision dans les données pour appuyer l’hypothèse avec certitude.

The thesis deals with the estimation of labour supply responses to the personal income tax reform in the Czech Republic adopted in 2008 by applying quasi experimental design known as "difference-in-differences". By exploiting the different change in the effective tax rates for various population subgroups as a natural experiment and using microdata from European Labour Force Sur- vey we constructed the treatment and control groups according to the highest attained level of education serving as a proxy for an income range that assigns an individual to the particular tax bracket before and after policy change. Analysing one-person households we found significant negative effect on the labour force participation and significant positive effect on the hours work of the treated by comparing these outcomes for the treatment and control groups in the baseline and follow up periods before and after the reform.

Political Finance Reform and Public Procurement:  Evidence from Lithuania. Can political donations buy influence? This paper studies whether firms trade political contributions for public procurement contracts. To answer this question, I focus on the Lithuanian political economy. Combining data on a large number of government tenders, the universe of corporate donors and firm characteristics, I examine how a ban on corporate donations affects the awarding of procurement contracts to companies that donated in the past. Consistent with political favoritism, contributing firms’ probability of winning goes down by five percentage points as compared to that of non-donor firms after the ban. Among different mechanisms, the hypothesis that corporate donors get confidential information on competing bids prevails. The empirical results are in line with predictions from a first-price sealed-bid auction model with one informed bidder. Evidence on firm bidding and victory margins suggests that contributing firms adjust their bids in order to secure contracts at a maximum revenue. I assess that tax payers save almost one percent of GDP thanks to the reform. Gender Quotas and the Quality of Politicians. We analyze the effects of the introduction of gender quotas in candidate lists on the quality of elected politicians, as measured by the average number of years of education. We consider an Italian law which introduced gender quotas in local elections in 1993, and was abolished in 1995. As not all municipalities went through elections during this period, we identify two groups of municipalities and use a difference-in-differences estimation. We find that gender quotas are associated with an increase in the quality of elected politicians, with the effect ranging from 0.12 to 0.24 years of education. This effect is due not only to the higher number of elected women, who are on average more educated than men, but also to the lower number of low-educated elected men. The positive effect on quality is confirmed when we measure the latter with alternative indicators, it persists in the long run and it is robust to controlling for political ideology and political competition. Affirmative Action and the Power of the Elderly. There is evidence that age matters in politics. In this article we study whether implementation of affirmative action policies on gender can generate additional effects on an alternative dimension of representation, namely, the age of politicians. We consider an Italian law which introduced gender quotas in candidate lists for local elections in 1993, and was abolished in 1995. As not all municipalities went through elections during this period, we can identify two groups of municipalities and use a difference-in-differences estimation to analyze the effect of gender quotas on the age of elected politicians. We find that gender quotas are associated with election of politicians that are younger by more than one year. The effect occurs mainly due to the reduction in age of elected male politicians and is consistent with the optimizing behavior of parties or of voters. Let the Voters Choose Women. Female under-representation in politics can be the result of parties' selection of candidates and/or of voters’ electoral preferences. To assess the impact of these two channels, we exploit the introduction of Italian Law 215/2013, which prescribes both gender quotas on candidate lists and double preference voting conditioned on gender. Using a regression discontinuity design, we estimate that the law increases the share of elected female politicians by 22 percentage points. The result is driven by the increase in preference votes cast for female candidates, suggesting a salient role of double preference voting in promoting female empowerment in politics.

O presente estudo buscou compreender os efeitos do uso de incentivos financeiros na produtividade dos beneficiários do Programa de Produtividade em Pesquisa (PPP) da Universidade Federal do Tocantins (UFT), sob a ótica da Economia Comportamental. Teve como objetivos, verificar se através dos incentivos, os indivíduos aumentaram ou não a produtividade em pesquisa. Buscou-se também, identificar quais as características individuais impactaram mais a propensão dos indivíduos a ingressarem no programa, bem como, analisar se os resultados obtidos convergiram ou divergiram da teoria da Economia Comportamental. Para alcançar o intento, foi realizada análise documental (AD), onde foram analisados os currículos lattes dos 125 integrantes da amostra. Em seguida, os dados foram sistematizados e a pontuação atribuída a cada indivíduo foi tabulada. Com os resultados obtidos na AD, utilizou-se os modelos econométricos Propensity Score Matching (PSM) e Diferença em Diferenças (DD) para aferir o efeito do tratamento. Como resultados, verificou-se através do modelo PSM que o efeito do tratamento no período da intervenção foi positivo. Já quando este resultado foi comparado com o período pré-intervenção, através da aplicação do modelo DD, verificou-se que o efeito do tratamento foi negativo. Constatou-se, porém, que o efeito negativo apontado pelo modelo DD decorreu da aproximação de desempenho dos integrantes do grupo controle (aumento de 84,69% na produtividade média do grupo), em relação aos integrantes do grupo de tratamento, e não pela diminuição do desempenho dos tratados, tendo em vista que, houve aumento de 13,68% na produtividade média do grupo, entre um período e outro. Ou seja, durante o período de vigência do programa, houve aumento da média de produtividade nos dois grupos analisados. No geral, os resultados alcançados convergiram com os pressupostos teóricos da Economia Comportamental. / The present study sought to understand the effects of the use of financial incentives on the productivity of beneficiaries of the Research Productivity Program (PPP) of the Federal University of Tocantins from the perspective of Behavioral Economics. The objective was to verify if through the incentives the individuals increased or not the productivity. It was also sought to identify which individual characteristics impacted more the individuals' propensity to enter the program as well as to analyze if the results obtained converged or diverged from the behavioral theory. To reach the intent, a documentary analysis (AD) was carried out, where the lattes resume of the 125 sample members were analyzed. Then the data were systematized and the score attributed to each individual was tabulated. With the results obtained in the AD, the econometric models Propensity Score Matching (PSM) and Difference in Differences (DD) were used to gauge the treatment effect. As results, it was verified through the PSM model that the treatment effect in the intervention period was positive. When this result was compared with the pre-intervention period through the application of the DD model, it was verified that the effect of the treatment was negative. It was observed, however, that the negative effect indicated by the DD model resulted from the approximation of the performance of the control group (increase of 84,69% in the average productivity of the group) in relation to the members of the treatment group, since there was an increase of 13,68% in the average of the treated individuals. That is, during the period of validity of the program, there was an increase in the average productivity of the two groups analyzed. In general, the results achieved converged with the theoretical assumptions of Behavioral Economics.

It is generally held that economic sanctions have an adverse effect on human rights in sanctioned countries, but what about the non-sanctioned countries? Previous research has found that human rights sanctions appear to have a deterring effect on non-sanctioned countries in Latin America which, in turn, led to human rights improvements. The assumption from these findings suggests that countries improve their human rights in fear of being sanctioned themselves. Utilising a difference-in-differences method with data from CIRI and PTS for the time period 1977-1996, the present quasi-experimental study attempts to test these findings on Africa and Asia by posing the hypothesis that economic sanctions improve the level of human rights protection in the non-sanctioned countries of the same geographical region. The results show that, while there appears to be a positive effect on some measures of human rights in non-sanctioned countries, these effects are weak. Moreover, the results also show that the improvements correspond with the number of years following a sanction, where 1 year displays the weakest human rights improvements, whilst 10 years displays the strongest. The conclusion is that there, in some cases, appears to be a modest effect which needs to be examined further, but that sanctions, nevertheless, do not improve human rights in neighbouring countries in a meaningful way.

In recent years several municipalities in Sweden have merged their public secondary schools. This has been considered a type of initiative that intends to reduce youth segregation and discrepancies in school quality. This thesis examines in what ways the merging of all public secondary schools in a municipality affects the students’ academic performance and their choice to enroll in the publicschool sector. To do so I use municipality-level aggregate data from the Swedish National Agency for Education on 9th grade students’ academic outcomes and the share of 7th graders enrolled in the public schools. I employ a difference-in-difference approach to estimate the reduced form effect of the school mergers. The control group used in the baseline estimation includes all municipalities that had a constant number of public secondary schools during the time period of my study. I move on to use propensity score matching in order to create a more comparable control group. I then estimate a difference-in-difference regression with match-fixed effects. The results show that the mergers have a negative effect on the municipality-level average GPA. In addition, the municipalities where the mergers have been implemented experience a reduction in the share of students that pass all 9th grade subjects as well as an increase in the share of students who do not have sufficient grades to continue to upper secondary school. The school mergers caused the share of 7th graders enrolled in the publicschool sector to decrease by approximately 10 percentage points. These results indicate that the public secondary school merger is not a panacea for improving student outcomes.
