This dissertation consists of three empirical essays on labor, health, and real estate economics. The first essay theoretically and empirically analyzed the effects of the costs of firing an employee and hiring a replacement in a labor market with imperfect information. The theory suggested that increased expected firing or replacement costs contributed to a ``lemons effect" for the fired worker through the negative signal received in the labor market regarding the worker's ability. To test this theory, data from the Displaced Worker's Supplement to the Current Population Survey from 2004 to 2014 was used. The results were mixed, but suggested that workers in the United States who were displaced from their job experienced decreased probabilities of finding reemployment as firing costs increased. The essay also examined whether this ``lemons effect" contributed to larger wage decreases, but the estimates did not support this conclusion. The second essay estimated the impacts of the 2001 elimination of the Medicare 24-month waiting period for non-elderly Amyotrophic Lateral Sclerosis (ALS) patients. Using data from the National Hospital Discharge Survey, this essay estimated the effects of the elimination on health insurance coverage and utilization of health care services. By applying a difference-in-difference OLS estimation technique, it was estimated that, as a result of the waiting period elimination, non-elderly ALS patients were more likely to be insured, but there was a significant crowd-out of private insurance. These non-elderly patients who were admitted to the hospital with serious symptoms were also more likely to be transferred to long- or short-term care facilities while non-serious patients were more likely to receive a high (four or more) number of medical services while hospitalized. In the third essay, the effects of a new suburban casino on local housing prices were evaluated. Similar to the second essay, a difference-in-difference approach was applied, but it was combined with a spatial hedonic pricing model. Using data from a GIS product from the Maryland Department of Planning and local-area data from the American Community Survey, the effects that the opening of Maryland Live! Casino had on home sales prices of properties located in primary (one-mile radius) and secondary (one to three miles) impact areas were estimated. The results of the estimations indicated that the opening of the casino had a positive impact on housing prices in the primary impact area and this impact likely began during the construction period. No impacts, however, were evident in the secondary impact area. / Economics

Syftet med denna undersökning har varit att studera vad RUT-avdragets införande 2007 har inneburit för anställda inom befintliga svenska aktiebolag inom RUT-branschen. RUTavdraget är en skattesubvention som innebär att privatpersoner kan få hushållsnära tjänster utförda till ett reducerat pris. Undersökningen har gjorts genom att empiriskt studera hur genomsnittlig lönesumma per anställd och genomsnittligt antal anställda i befintliga svenska aktiebolag har förändrats inom RUT-branschen mellan åren 2006 och 2008, allt annat lika. För att studera detta användes en difference-in-difference-metod med fixa effekter och robusta standardfel. Datamaterialet som användes till undersökningen var bokföringsdata från aktiebolag som samlats in av PAR. I undersökningen ingick 2 506 företag inom RUTbranschen och totalt 74 798 observationer. Resultatet visar att i genomsnitt har det inom de befintliga aktiebolagen inom branschen skapats 1,4 nya jobb per företag och årslönerna för de anställda i dessa företag har i genomsnitt ökat med 10 931 kronor per anställd. Totalt innebär det att 3 065 nya jobb har skapats i dessa befintliga aktiebolag, vilket kan sättas i relation till tidigare undersökningar som visat att den totala ökningen av antal anställda i genomsnitt varit ca 5 700 personer. Tidigare har inte löneeffekter till följd av RUT-avdraget studerats, vilket innebär att detta arbete bidrar med ny forskning inom ett område som inte studerats tidigare. / The purpose of this thesis has been to study what the introduction of the RUT deduction 2007 has meant for employees in existing Swedish limited companies in the RUT industry. The RUT deduction is a tax subsidy that allows the public to buy household services at a reduced price. The study has been conducted by empirically studying how average wages per employee and average number of employees in existing Swedish limited companies have changed within the RUT industry between 2006 and 2008, ceteris paribus. For this, a Difference-in-Difference method was used with fixed effects and robust standard errors. The data used for the study was accounting data from companies, collected by PAR. The dataset consisted of 2,506 companies in the RUT industry and a total of 74,798 observations. The result shows that on average, within the existing companies in the industry, 1.4 new jobs have been created per company and the annual salary for employees in these companies has increased by an average of SEK 10,931 per employee. In total, 3,065 new jobs have been created in these existing limited companies, which can be compared with previous studies where the average number of employees on average was approximately 5,700. Previously, wage effects resulting from the RUT deduction have not been studied, which means that this work contributes to new research in a previously unexplored area.

Subsidies to professional sports teams remain a controversial issue, and in most European countries these subsidies have decreased over the past decades. However, in Sweden they are a common occurrence, municipalities are giving generous amounts of money to their local team. To justify these subsidies, proponents of sports team claim their great economic impact on the local area. Nevertheless, in the sport economic literature, most of the researchers cannot find any positive impact and some of them even find negative impact from a hosting a professional sports team. This study will give an explanation and extension to the earlier articles about sport economics written in Sweden by Emelie Värja (2014) and Lars Behrenz (2009). In this essay we will present two models. The idea behind our first model is to investigate if professional sport events should be considered as a substitute to other leisure activities. This model indicates that there is a substitution effect between ice hockey games and cinema admissions in Sweden. The outcome from our other model which studies the condominium market strongly contradicts the generous sport subsidies given by Swedish municipalities. The results indicate that the presence of a professional ice hockey team lowers the condominiums prices.

O mercado de trabalho de motoristas de caminhão no Brasil é de suma importância para a economia nacional, já que contempla cerca de 2 milhões de caminhoneiros e 61% do transporte de cargas do País é feito pelas rodovias. No entanto, há alguns problemas: os caminhoneiros trabalham sobre um regime de horas exaustivo, o que ocasiona externalidades negativas sérias na economia, como distúrbios de saúde e graves acidentes nas estradas. Nesse contexto, o presente trabalho, com base nos dados da PNAD-IBGE, teve dois objetivos: i) para todo o período de 2002 a 2015, realizamos uma análise socioeconômica dos motoristas de caminhão no Brasil; ii) analisamos os impactos da \"Lei do Descanso\" (2012) e da \"Lei do caminhoneiro\" (2015) sobre características importantes do mercado de trabalho dos caminhoneiros. Para a primeira parte, encontramos para 2015 que cerca de 62% dos motoristas de caminhão possuem somente até o Ensino Fundamental; 78% ganham de 1 a 3 salários mínimos; 58% trabalham com carteira assinada e 28% por conta própria; 43% trabalham mais do que 44 horas semanais. Com relação à evolução dessas características ao longo do período analisado, comparamos elas com os atributos do mesmo grupamento ocupacional dos caminhoneiros. Quanto ao rendimento, em 2002, a diferença era de R$ 750,00; em 2015, caiu para R$ 550,00. Já para as horas trabalhadas na semana, em 2002, essa diferença era de 10 horas, passando para 5 horas em 2015. Com respeito ao segundo objetivo, investigamos o efeito das leis mencionadas sobre o rendimento, a jornada de trabalho e a formalização do trabalho dos motoristas de caminhão, utilizando o estimador de diferenças em diferenças com ponderação pelo escore de propensão. Não encontramos efeitos da \"Lei do descanso\" sobre rendimentos e formalização. No entanto, houve, para 15 meses após a vigência da legislação, redução de cerca de uma hora para a jornada de trabalho semanal dos caminhoneiros. No que diz respeito à \"Lei do caminhoneiro\", nossas estimações mostraram que essa lei reduziu o número de horas trabalhadas pelos motoristas de caminhão em cerca de uma hora. Contudo, um dos efeitos adversos da vigência da lei foi a diminuição do rendimento mensal desses profissionais em aproximadamente R$ 70,00. Dessa maneira, pode-se concluir que o governo obteve êxito em reduzir o número de horas trabalhadas pelos caminhoneiros. / The labor market of truck drivers in Brazil is of paramount importance to the national economy, since it includes about 2 million truck drivers and 61 % of the country\'s cargo transport is done by road. However, there are some problems: truck drivers work on an exhausting hours regime, which causes serious negative externalities in the economy, such as health disturbances and serious road accidents. In this context, the present study, based on PNAD-IBGE data, had two objectives: i) for the entire period from 2002 to 2015, we carried out a socioeconomic analysis of truck drivers in Brazil; ii) we analyze the impacts of the \"Lei do descanso\" (2012) and the \"Lei dos caminhoneiros\" (2015) on important characteristics of the labor market of truck drivers. For the first part, we find that about 62% of truck drivers only have until Elementary School; 78% earn from 1 to 3 minimum wages; 58% work with a formal contract and 28% on their own. Regarding the evolution of these characteristics over the analyzed period, we compare them with the attributes of the same occupational grouping of the truck drivers, so that both have similar characteristics. As for income, in 2002, the difference was R$ 750.00; in 2015, fell to R$ 550.00. For the hours worked in the week, in 2002, this difference was 10 hours, going to 5 hours in 2015. With respect to the second objective, we investigated the effect of the mentioned laws using the difference-in-difference estimator weighted by the propensity score. We did not find statistically significant results of the effect of the \"Lei do descanso\" on income and formalization. However, we noted, for 15 months after the legislation was in force, a reduction of about one hour for the truckers\' weekly working day. Regarding the \"Lei do caminhoneiro\", our estimates showed that this law reduced the number of hours worked by truck drivers in about an hour. However, one of the adverse effects of the enactment of the law was to reduce the income of these professionals by approximately R$ 70.00. In this way, it can be concluded that the government succeeded in reducing the number of hours worked by the truck drivers.

nÃo hà / O presente estudo buscou evidenciar a atividade de Monitoramento Fiscal adotada durante os Ãltimos anos pelos Fiscos Estaduais e Federal como ferramenta alternativa no combate a sonegaÃÃo fiscal. A Ãnfase do trabalho està no Monitoramento Fiscal desempenhado pela Secretaria da Fazenda do Estado do CearÃ. O objetivo principal foi de realizar uma investigaÃÃo dos impactos do Monitoramento Fiscal no comportamento dos contribuintes utilizando como variÃvel explicativa a arrecadaÃÃo de ICMS do Estado do CearÃ. Para tanto, utilizou-se a metodologia economÃtrica diferenÃa em diferenÃa, cuja amostra de dados necessÃria para a aplicaÃÃo desta metodologia foi fornecida pela Secretaria da Fazenda do Estado do Cearà sendo os dados cadastrais dos contribuintes omitidos face ao sigilo fiscal. Observou-se que o coeficiente nÃo foi estatisticamente significativo para os segmentos da indÃstria, comÃrcio varejista e serviÃo de transporte, no entanto, os resultados apontam que para o segmento econÃmico de comÃrcio atacadista, a atividade de Monitoramento Fiscal influenciou no comportamento dos contribuintes com um incremento de 73% na arrecadaÃÃo mÃdia de ICMS. / This present study we sought show the activity of Tax Monitoring adopted during the last years for Department of Finance of the States and Federal with alternative tool in the fighting tax evasion. The emphasis this work is in Tax Monitoring executed for Department of Finance of the State of CearÃ. The main objectives this work was does investigation impacts of Tax Monitoring on behavior of taxpayers using with explanatory variable the collection of ICMS. For that, we used the method econometric âdifference in differenceâ, which a information database from the Department of Finance of the State of Cearà and the records dates was omited because tax secrecy. The results shows that coefficient were not significant statistically for economic segments of industry, retail sale and trasnport, but, the results indicate that Tax Monitoring promoted for the wholesale segment a positive impact of 73% on the collection of ICMS.

This thesis investigates the impacts of user choice in Swedish elderly care on quality and cost as well as the impact of marketisation on the Covid-19 death toll. In the last three decades welfare service provision in Sweden has been increasingly marketised. Since 2009, Swedish municipalities have been able to introduce user choice in elderly care and it has been widely adopted in home care. To investigate the impact of introducing user choice, new insights from econometrics literature is used to estimate a staggered Difference-in-Difference model, using panel data for the years 2003-2019 and the 290 Swedish municipalities. The impact of marketisation on the Covid-19 death toll is estimated through Ordinary Least Squares using a cross-sectional data set. There are three main findings of this thesis. (i) The impact on quality and cost of the introduction of user choice has had heterogeneous effects across adoption groups, calendar time, and exposure length of treatment, and hence, the standard Difference- in-Difference approach is likely to provide biased estimates in this setting. (ii) The introduction of user choice has no clear effect on non-contractible quality measured by mortality rate and fall accidents, nor on cost. However, user choice has increased subjective quality, as measured by user satisfaction. (iii) A higher degree of marketisation in home care is associated with a higher Covid-19 death toll amongst those which had home care.

Vilka är effekterna av klassrummens digitala anpassningar i händelserna av en pandemi? Covid-19 har globalt sedan slutet av 2019 i olika omfattning och takt påverkat världsekonomin, den sociala mobiliteten och för Sverige likt många andra länder även skolbänken. Som ett led i stegen av Folkhälsomyndighetens rekommendationer som syftar till att motverka smittspridningen har klassrumsundervisning på riksnivå avlösts av olika hybrider av distansundervisning. Hur distansundervisningen påverkat Sveriges elever har varit ett föremål för debatt i de politiska rummen såväl som vid zoom-möten. Denna uppsats syftar till att undersöka sambandet mellan utvecklingen av flickors och pojkars betygspoäng på de obligatoriska nationella proven i ämnet engelska, matematik och svenska och etableringen av distansundervisningen i Sverige. Studien grundas på en Difference-in-Difference-in-Differences, en metod vars design utgår från inducerad slumpmässig variation. Nollhypotesen motsvarande att den logaritmerade genomsnittliga betygspoängen bland flickor och pojkar är likadan kommer via Welchs approximation testas för att se om utrymme finns för tolkningen att distansundervisningen kan ha påverkat trenden mellan betygspoängen och könstillhörigheten. Resultaten visar på att det inte går att avvisa att variationen i betygspoäng är orsakad av slump i engelska och matematik, men att skillnaden i genomsnittlig betygspoäng är statistiskt signifikant i svenska och har minskat mellan flickor och pojkar. Tre kompletterande hypotesprövningar görs på om andelen elever som fått underkänt betyg bland flickor och pojkar är signifikant lika i syfte att nyansera eventuella effekter av distansundervisningen, och för att undersöka om “Boys Will Be Boys” stämmer på de obligatoriska nationella proven. Resultaten på de kompletterande hypotesprövningarna är statistiskt signifikanta i respektive ämne och indikerar att skillnaderna minskat mellan flickor och pojkar. Modellen tar inte hänsyn till andra förklarande variabler än kön, varpå det uppmuntras till att tolka resultaten i ljuset av en inledande debatt kring könssegregationen i skolan.
