Essay I (with Mattias Öhman): Fluoridation of the drinking water is a public policy whose aim is to improve dental health. Although the evidence is clear that fluoride is good for dental health, concerns have been raised regarding potential negative effects on cognitive development. We study the effects of fluoride exposure through the drinking water in early life on cognitive and non-cognitive ability, education and labor market outcomes in a large-scale setting. We use a rich Swedish register dataset for the cohorts born 1985-1992, together with drinking water fluoride data. To estimate the effect we exploit intra-municipality variation of fluoride, stemming from an exogenous variation in the bedrock. First, we investigate and confirm the long-established positive relationship between fluoride and dental health. Second, we find precisely estimated zero effects on cognitive ability, non-cognitive ability and education. We do not find any evidence that fluoride levels below 1.5 mg/l have negative effects. Third, we find evidence that fluoride improves labor market outcome later in life, which indicates that good dental health is a positive factor on the labor market. / Essay II: Motivated by the intense public debate in the United States regarding politicians’ backgrounds, I investigate the effects of electing a candidate with earlier experience from elective office to the House of Representatives. The U.S. two-party-system with single-member election districts enables me to estimate the causal effect in a RD design where the outcomes are measured at the election district level. I find some indications that candidates with earlier elective experience are more likely to be members of important congressional committees. I also find some indications that directed federal spending (pork barrel spending) is higher in those districts were the elected representative had earlier elective experience prior of being elected to the House, but the effect manifests itself some years after the election. In contrast, I find no robust or statistically significant effects for personal income per capita or unemployment rate in the home district. / Essay III: This paper uses Swedish and Finnish municipal data to investigate the effect of changes in voter turnout on the tax rate, public spending and vote-shares. A reform in Sweden in 1970, which overall lowered the cost of voting, is applied as an instrument for voter turnout in local elections. The reform increased voter turnout in Sweden. The higher voter turnout resulted in higher municipal taxes and greater per capita local public spending. There are also indications that higher turnout decreased the vote share for right-wing parties. I use an individual survey data set to conclude that it was in particular low income earners that began to vote to a greater extent after the reform. / Essay IV (with Lovisa Persson): In a theoretical model where voters and politicians have different preferences for how much to spend on basic welfare services contra reception services for asylum seekers, we conclude that established politicians that are challenged by right-wing populists will implement a policy with no spending on asylum seekers if the cost is high enough. Additionally, adjustment to right-wing populist policy is more likely when the economy is in a recession. Voters differ in their level of private consumption in such a way that lower private consumption implies higher demand for basic welfare services at the expense of reception of asylum seekers, and thus stronger disposition to support right-wing populist policies. We propose that this within-budget-distributional conflict can arise as an electorally decisive conflict dimension if parties have converged to the median voter on the size-of-government issue.

Explaining the rising support for right-wing populist parties in Europe during the last decade is an issue that interests both economists, sociologists and political scientists. A number of theories suggest that the rising inflow of migrants to Europe has had an important causal effect on right-wing populist support. However, as migration patterns generally are not exogenous to right-wing populist support, it is difficult to interpret the estimates of a correlation study causally.  In this paper, I exploit a Swedish refugee dispersal program as a natural experiment to estimate the effect of refugee inflow on the support for the right-wing populist party the Sweden Democrats using an instrumental variable strategy. Despite detailed institutional knowledge, I am not able to find support for any short-term effects of refugee inflow on the self-reported preferences for the Sweden Democrats. This goes against the findings of most previous studies.  However, the multicollinearity of some of my covariates are high. In addition, as the program was introduced in 2016, there are few years available for identification. Thus, the precision of the estimates is relatively low and the study would benefit from adding more years to the panel data set.

Essay 1 (with Mikael Elinder): We show that house prices in general did not respond to a large cut in the property tax in Sweden. Our estimates are based on rich register data covering more than 100,000 sales over a time period of two and a half years. Because the Swedish property tax is national and thus unrelated to local public goods, our setting is ideal for causal identification of the property tax on house prices. Our result that house prices did not respond to the tax cut at the time of implementation cannot be explained by early capitalization at the time of announcement. Two other stories appear to explain our results. First, it is possible that house buyers expect an offsetting increase in the supply of housing. Second, house buyers might simply not understand how the tax cut affects total future costs of owning a house. Unfortunately, it has proven difficult to disentangle the two mechanisms, and we must therefore conclude that both may be relevant. Essay 2:  I investigate government consumption smoothing (sensitivity) under a balanced budget rule in Swedish municipalities. In general, I find Swedish municipalities to be highly consumption sensitive. Municipalities consume 87.6% out of predicted current revenues in the time period leading up to the implementation of the balanced budget rule, and they consume 76.3% out of predicted current revenue in thetime period following the implementation. Fiscally weak municipalities are found to be more consumption sensitive than fiscally strong municipalities. Very weak municipalities have become more consumption sensitive compared with very strong municipalities since the implementation of the balanced budget rule. Thus, I find indicative evidence that both credit market constraints and formal budget rules such as balanced budget rules increase municipal consumption sensitivity Essay 3: Using the Swedish municipal sector as my political laboratory, I study the effect of a coalition partner on policy outcomes. I use a version of Regression-Discontinuity Design (RDD) specifically suited to proportional systems to define close elections, which can be used for identifying the effect of the Left Party as coalition partner to the Social Democrats. The Left Party is found to have a positive and medium sized effect on the municipal income tax rate. The positive effect is in line with what we expect given the policy preferences of Left Party representatives, but also given the predictions from political fragmentation theory. I find no effects on expenditures or debt, and the negative result for investments is not robust. Essay 4 (with Linuz Aggeborn): In a model where voters and politicians have different preferences for how much to spend on basic welfare services contra immigration, we conclude that established politicians that are challenged by right-wing populists will implement a policy with no spending on immigration if the cost of immigration is high enough. Additionally, adjustment to right-wing populist policy is more likely when the economy is in a recession. Voters differ in their level of private consumption in such a way that lower private consumption implies higher demand for basic welfare services at the expense of immigration, and thus stronger disposition to support right-wing populist policies. We propose that this within-budget-distributional conflict can arise as an electorally decisive conflict dimension if parties have converged to the median voter on the size-of-government issue. / <p>Felaktigt isbn: 978-91-85519-61-3</p>

Sverigedemokraterna är ett radikalt högerpopulistiskt parti som fortsätter att öka sedan valet år 2010. Vid en opinionsundersökning i april 2012 skulle partiet få 8 procent av medborgarnas röster. Syftet med vår uppsats är att förstå och förklara vilka orsaker som ligger till grund för att allt fler medborgare röstar på Sverigedemokraterna. För att kunna besvara syftet med uppsatsen har vi valt att göra en kvalitativ studie genom att med semistrukturerade intervjuer undersöka upplevelser och attityder till dagens samhällsförändringar bland Sverigedemokraternas väljare och relatera deras upplevelser till tidigare forskning inom ämnet. För att besvara vårt syfte blir frågeställningarna följande: På vilket sätt kan SD som parti locka allt fler väljare i dagens globaliserade Sverige? Vilka faktorer kan ligga till grund för att vissa medborgare röstar på SD? Samt vad tror de att SD kan bidra med och förändra i det svenska samhället och mer specifikt för deras egen situation? Vårt teoretiska ramverk är globalisering, representationen ”Vi och Dom”, nation/nationalism och välfärdschauvinism. Med dessa teorier kommer vi ur ett sociologiskt perspektiv förklara vilka samhällsprocesser som interagerar med väljarnas vardagssituation och därmed ligger till grund för deras politiska beslut. Det slutgiltiga resultatet visar att radikal högerpopulistisk retorik är genomgående i samtliga intervjuer. Invandring och välfärdsfrågor var det viktigaste faktorerna till varför intervjupersonerna röstade på Sverigedemokraterna. / The Sweden Democrats is a radical right wing party who continue to increase since the elections in 2010. At a poll in April 2012, the party would get 8 percent of the votes. The purpose of our paper is to understand and explain the reasons underlying that more and more citizens vote for the Sweden Democrats. To be able to respond to the purpose of the paper, we have chosen to make a qualitative study by using semi-structured interviews examine the experiences and attitudes of today's social changes among the Sweden Democrats ' voters and relate their experiences to the previous research on the subject. To answer our purpose becomes the following questions: In what way can the SD as an increasing number of voters in the party attract today's globalized Sweden? What factors can serve as the basis for that some citizens vote on SD? What do they think that SD can contribute and change in Swedish society and more specifically for their own situation? Our theoretical framework is globalization, representation "We and Them" nation/nationalism and welfare-chauvinism. With these theories we come from a sociological perspective to explain what social processes that interact with voters ' living situation and thus is the basis for their policy decisions. The final result shows that radical right wing rhetoric is consistently in all interviews. Immigration and welfare issues were the main factors why the respondents voted for the Sweden Democrats.
