Mongolia is a country whose Gross Domestic Income relies heavily on raw material prices. The recent downturn in important commodity prices like copper or coal affect national income, taxes and the social welfare system. Mongolia should try to diversify its industries further to become less dependent on commodity business cycles. Mongolia should also try to lower the rate of corruption, which in many countries is highly correlated with mining businesses. Modern high tech companies and business technologies are corruption averse. Relationships based on corruption are short-lived and instable. This is what those companies do not like. A country like Mongolia that strives towards high wealth and less dependence on commodities should try to get rid of corruption.

Die gegenwärtige Regelung der SächsPfleinrVO für gesondert berechenbare Aufwendungen nach § 82 Abs. 3 SGB XI für Investitionen und Instandhaltungsaufwendungen in Pflegeeinrichtungen enthält einige grundlegende Problembereiche, die einer ökonomischen Logik systematisch widersprechen. Gegenstand des Gutachtens ist die Darstellung der verschiedenen Problembereiche der SächsPfleinrVO und möglicher Lösungsmöglichkeiten. Die Problembereiche können dabei in vier Bereiche zusammengefasst werden: 1. Systematische Problematiken der SächsPfleinrVO 2011/13 2. Verbraucherschutzprobleme der Neuregelung 3. Ausgelöster Verwaltungsaufwand durch die neue SächsPfleinrVO 2011/13 4. Probleme in der operativen Umsetzung der SächsPfleinrVO 2011/13 Dem Erkenntnisinteresse des Auftraggebers folgend liegt der Analyseschwerpunkt bei Problemen, die insbesondere aus Pflegeeinrichtungen resultieren, die vollstationäre Dauerpflegeplätze anbieten. Nach der Darstellung der rechtlichen Grundlagen und der Datengrundlage des Gutachtens, werden diese vier Problembereiche anhand von Beispielen erläutert und mögliche Problemlösungen vorgeschlagen. Mit einer Zusammenfassung und Schlussfolgerungen wird ein Fazit gezogen.

Die vorliegende Dissertation besteht aus vier Kapiteln zum Thema Steuerfehlwahrnehmung. Kapitel 1 gibt einen Überblick über die bisherige Literatur und systematisiert sie durch die Entwicklung des Behavioral Taxpayer Response Model. Das Ausmaß der Steuerfehlwahrnehmung wird u.a. durch die Verfügbarkeit von Informationen und persönliche Merkmale beeinflusst. Auch wenn Steuerinformationen verfügbar sind, schätzen die Steuerpflichtigen die Steuerlast falsch ein, weil sie sich in einem begrenzten Maße rational verhalten. Die umfangreiche Literatur zeigt auch, dass es nur wenig Literatur in Bezug auf Unternehmen gibt. Wir schließen diese Forschungslücke in Kapitel 2, indem wir die Fehlwahrnehmung durch Unternehmen in Deutschland analysieren. Um Datenbeschränkungen zu überwinden, verwenden wir einen innovativen Ansatz, der robuste Schätzungen liefert. Im Allgemeinen nehmen die Unternehmen ihre durchschnittlichen Steuersätze und Grenzsteuersätze deutlich verzerrt wahr und haben Probleme mit dem Konzept des Grenzsteuersatzes. Fehlwahrnehmungen werden tendenziell von der Komplexität, dem Steuerwissen und der Unzufriedenheit mit dem Steuersystem beeinflusst. Im Zusammenhang mit der Vermögensbesteuerung zeigen wir in Kapitel 3 anhand eines Umfrageexperiments, dass die Fehlwahrnehmung der jährlichen Vermögensteuer aufgrund ihrer mathematischen Komplexität zu einer verzerrten Präferenz führt. Die Information über die tatsächliche Steuerbelastung führt zu deutlich niedrigeren präferierten Steuersätzen. In dem abschließenden Kapitel 4 überprüfen wir die Ergebnisse einer Studie zur Steuervermeidung, die von den Grünen/EFA im Europäischen Parlament in Auftrag gegeben wurde. Diese Studie erregte große Aufmerksamkeit, weil sie behauptete, dass Unternehmen in Deutschland weit weniger Steuern zahlen, als der gesetzliche Steuersatz vermuten ließe. Wir zeigen, dass die Ergebnisse falsch sind und tragen damit zur Steuertransparenz in Deutschland bei. / This dissertation consists of four chapters on tax misperception. Chapter 1 reviews the previous literature on tax misperceptions and systematizes it through the development of the Behavioral Taxpayer Response Model. The extent of tax misperception is determined by information availability and personal characteristics. Under the assumption that tax information is available, taxpayers may even misperceive the tax burden because they behave in a rational bounded manner. The extensive literature also shows that there is little literature on corporations. We address this research gap in Chapter 2, which analyzes the misperception of tax rates by firms in Germany. To overcome data limitations, we use an innovative approach to measure tax misperception that provides robust estimates. In general, firms significantly misperceive their average (ATR) and marginal tax rates (MTR) and have problems with the concept MTR. Misperceptions tend to be influenced by the complexity of the tax system, tax knowledge, and satisfaction with the current tax system. In the context of wealth taxation, we use a survey experiment in Chapter 3 to show that misperception of a yearly wealth tax, due to its mathematical complexity, leads to a biased preference for wealth taxation. Informing respondents about the actual tax burden leads to significantly lower preferred tax parameters. In the final Chapter 4, we question the findings of a study on tax avoidance commissioned by the Greens/EFA in the European Parliament. This study attracted media attention because it claimed that companies in Germany pay far less tax than the statutory tax rate would suggest. We demonstrate that their findings are wrong and help to increase tax transparency in Germany.

The study is intended to identify relevant channels and possibly biasing factors with respect to fiscal multipliers, and thus to contribute to improving the precision of multiplier forecasts. This is done by, first, defining the concept of the multiplier used in the present study, presenting the main theoretical channels of influence as discussed in the literature and the problems of empirical identification. Second, by conducting a meta-regression analysis on the reported multipliers from a unique data set of 1069 multiplier observations and the respective study characteristics in order to derive quantitative stylzed facts. Third, by developing a simple multiplier model that explicitly takes into account the time elapse of the multiplier process as an explanatory factor that has been largely overlooked by the relevant theoretical literature. Fourth, by identifying, for US macroeconomic time series data, the extent to which fiscal multiplier estimates could be biased in the presence of financial cycles that have not been taken into account by the relevant empirical literature.:List of Figures IV List of Tables VI List of Acronyms VII List of Symbols IX 1 General Introduction, Aim and Scope 2 Principles of the Measurement, Theory and Estimation of Fiscal Multipliers 2.1 Introduction 7 2.2 Definition and Measurement of the Fiscal Multiplier 7 2.3 Determinants of the Fiscal Multiplier 14 2.4 Principles of Estimating Fiscal Multipliers 29 2.5 Conclusions 38 3 A Meta-Regression Analysis of Fiscal Multipliers 43 3.1 Introduction 43 3.2 Literature Review 45 3.3 Data Set and Descriptive Statistics 49 3.4 Meta Regression—Method 54 3.5 Meta Regression—Moderator Variables 56 3.6 Meta Regression—Results 60 3.7 Conclusions 74 4 The Multiplier Principle, Credit-Money and Time 82 4.1 Introduction 82 4.2 Literature Review 85 4.3 Developing an Augmented Multiplier Model 89 4.4 Dynamic Stability of the Multiplier Process 106 4.5 Identifying the Lag-length 109 4.6 Conclusions 111 5 Financial Cycles and Fiscal Multiplier Estimations 114 5.1 Introduction 114 5.2 Literature Review 116 5.3 Asset and Credit Markets and Fiscal Multiplier Estimations 118 5.4 A Formal Framework 120 5.5 Empirical Strategy 124 5.6 Data 125 5.7 Structure and Identification 126 5.8 Effects of Fiscal Policy Changes—Baseline vs. Augmented Models 132 5.9 Robustness 140 5.10 Conclusions 142 6 General Conclusions and Research Prospects 148 Bibliography 153

Die vorliegende Arbeit besteht aus vier Aufsätzen zum Thema Besteuerung, welche sich in drei Themenblöcke unterteilen lassen: Die ersten beiden Aufsätze dieser Arbeit (Maiterth/Chirvi 2015 sowie Chirvi 2019) widmen sich dem deutschen Ehegattensplitting, der dritte Beitrag (Chirvi/Maiterth 2019) behandelt die Besteuerung gesetzlicher Renten in Deutschland und der vierte Aufsatz (Chirvi/Schneider 2019) untersucht Präferenzen bzgl. der Besteuerung von Vermögen in den USA. Eine Aufteilung anhand der behandelten Steuerarten macht die Arbeit noch übersichtlicher: So behandeln die ersten drei Aufsätze jeweils Aspekte der Einkommensteuer, während sich der vierte Beitrag verschiedenen Arten der Vermögensbesteuerung widmet. Es lässt sich ergänzen, dass die Aufsätze zur Einkommensteuer sehr eng mit dem deutschen Steuerrecht verbunden sind. Sie beschäftigen sich mit existierenden Regelungen (§ 26 sowie 32a EStG zum Ehegattensplitting bzw. § 10 sowie 22 EStG zur Rentenbesteuerung) und deren Auswirkungen. Dies gilt insbesondere für die Beiträge Maiterth/Chirvi (2015), in dem ein Forschungs- und Rechtsprechungsüberblick zum Thema Ehegattensplitting geliefert wird, sowie Chirvi/Maiterth (2019), in dem eine potentielle Doppel- oder Minderbesteuerung gesetzlicher Renten durch das AltEinkG untersucht wird. Der Aufsatz Chirvi (2019) untersucht Arbeitsangebotswirkungen des Ehegattensplittings und ist daher etwas weniger eng mit dem deutschen Recht verknüpft, da sich zumindest ähnliche Regelungen auch in anderen Ländern finden. Der Beitrag zur Vermögensbesteuerung, Chirvi/Schneider (2019), untersucht dagegen Präferenzen in Bezug auf – bis auf die Nachlasssteuer („estate tax“) – nicht existierende Vermögensteuern in den USA. Zwei der Aufsätze wurden in der Zeitschrift Steuer und Wirtschaft publiziert, die anderen beiden wurden in der arqus Working-Paper-Reihe veröffentlicht. / This dissertation consists of four papers on taxation that can be divided into three different subject areas: The first and the second paper (Maiterth/Chirvi 2015 as well as Chirvi 2019) deal with the ‘income splitting’, i.e. the taxation of married couples in Germany. The third paper (Chirvi/Maiterth 2019) analyzes effects of a reform regarding the transition to downstream taxation of public pensions. Finally, the last paper (Chirvi/Schneider 2019) examines preferences for the taxation of wealth in the United States. While the first three papers analyze (the effects of) specific regulations within the German income tax code (income splitting in Art. 26 and 32a of the German income tax code; the taxation of public pensions in Art. 10 and 22 of German income tax code), the fourth essay is about partially hypothetical types of capital taxation. Maiterth/Chirvi (2015) review the literature on the topic in the areas of public economics, business taxation and tax law and compile arguments for and against the income splitting. As many researchers point out that the income splitting may lead to disincentives for married women to work, Chirvi (2019) empirically analyzes its labor supply effects based on a new approach. Chirvi/Maiterth (2019) evaluate whether the AltEinkG, a reform that lead to a successive transition to downstream taxation, results in under- or double taxation of public pensions in Germany. They develop a measure and subsequently estimate potential under- or double taxation based on official income tax data. Chirvi/Schneider (2019) are interested in preferences regarding capital taxation and conduct a survey-experiment on mTurk to reveal whether preferences depend on the type of tax and/or attributes of assets and personal characteristics. Two of these papers have already been published in the scientific journal Steuer und Wirtschaft, the others can be found in the arqus working-paper series.
