本論文主要由兩篇文章所組成，探討有關跨國購併活動中目標公司的選擇，以及聯貸市場中參貸銀行的選擇。第一部份旨在分析市場集中程度與跨國購併在垂直相關產業的議題。Beladi, Chakrabarti and Marjit (2013)建立一般均衡寡佔模型，連結當地國的市場競爭力和跨國購併在垂直相關產業的論點。他們模型認為當地國家的垂直整合程度會改變國外主併者策略優勢。我們使用1990年至2012年涵蓋86個國家，之全球購併活動案件，我們衡量當地國家的市場競爭與垂直整合程度，呈現當地國家前期的市場競爭力將會誘發國外市場主併者進入，以垂直購併的方式購併當地國家之目標公司。本研究結果提供了實證性的結果來支持過去理論之發現，認為產業的集中程度會影響跨國購併。 本論文的第二部份，在研究知識技能互補和銀行商譽在參貸銀行的選擇，觀察主貸銀行該如何選擇參貸銀行之決策分析。延伸Diamond (1991)的商譽建立假說，透過主貸銀行本身的特性因子與工作經驗，來探討主貸銀行選擇參貸銀行的誘因動機。研究結果發現，當主貸銀行具有較高的自身商譽佳、經營及投資具效率性、內部監理機制較佳、且市場經驗較為豐富時，會誘使主貸銀行減少對高商譽參貸銀行的需求。呈現知識技能互補的現象於主貸銀行選擇參貸銀行的決策。本研究結果可提供我們對聯貸銀行團商譽互補現象及分析。 / Two essays are comprised in this dissertation to study on choices of target firms in cross-border M&As and choices of participant banks in the syndicated loan market. In the first essay, cross-border mergers and market concentration in a vertically related industry, we examine the relationship between market concentration and cross-border M&A. Beladi, Chakrabarti and Marjit (2013) present an oligopoly in general equilibrium model to identify the linkages between local market competition and cross-border mergers in a vertically related industry. Their model predicts that a vertical integration at home changes the strategic advantage for foreign acquirers. Using firm-level data from 86 countries between 1990 and 2012, we calculate proxies for local market competition and show that lower (higher) pre-merger local competition at home country will increase (decrease) mergers between a foreign firm and a vertically integrated home firm. These findings provide empirical supports for the significant impact of industry concentration on the decisions of cross-border M&A. In the second essay, the effects of knowledge complementarities and bank reputation on participant banks choices, we focus on the decision of lead arrangers on participant bank choices in the syndicated loan market. We extend reputation building theory (Diamond, 1991) and model the lead arranger’s partner choice problem through the effect of self-related and task-related factors. Our paper show that when lead arrangers have higher reputation, operating efficiency, and market experience, lead arrangers tend to choose less reputable partners. These results help to explain how lead arrangers, through their partner selection decisions, manage the reputation pool among banks in the syndicated loan market.

This dissertation consists of three research papers dealing with selected issues relevant for central banks after the global financial crisis. The post-crisis world has seen a significant strengthening of the role of central banks with regard to the financial system as well as the real economy. Correspondingly, agendas of some central bankers have grown substantially, encompassing among others monetary policy, financial stability (macro- and microprudential policies) as well as resolution mechanisms. This dissertation thesis reflects the broad focus of some contemporary central banks in three original research articles that concern current unexplored issues for monetary policy and financial stability in the European Union, the Czech Republic, and the United States, potentially bringing policy implications for the relevant authorities. The first article analyzes inflation convergence in the whole European Union (EU) over 1999-2017 and provides comprehensive and robust evidence that the process of inflation convergence among the countries of the EU was not permanently disrupted during the global financial crisis, the European sovereign debt crisis, or the period of zero lower bound interest rates. Specifically, the convergence process did not noticeably weaken after the crisis and the occurrence of...

Diese Dissertation umfasst drei Studien über Finanzberichterstattung gemäß International Financial Reporting Standards (IFRS) und Wirtschaftsprüfung. Da die IFRS ein prinzipienbasiertes Standardsystem sind, haben Abschlussersteller beabsichtigte Ermessensspielräume bei der Erstellung ihrer Finanzberichte. Die ersten beiden Studien widmen sich den Fragen, wie genau Abschlussersteller entsprechende Ermessensspielräume ausüben und inwieweit dies von der Wahl des Abschlussprüfers abhängt. Die erste Studie untersucht die Anhangangaben zu Ermessensentscheidungen und Schätzunsicherheiten (gemäß IAS 1). Sie liefert deskriptive Belege für ein insgesamt zunehmendes Niveau der Offenlegung dieser Anhangangaben und dafür, dass das Offenlegungsniveau über verschiedene Abschlussprüfer hinweg variiert. Inspiriert durch die Ergebnisse der ersten Studie widmet sich die zweite Studie der Frage, welche Arten von Abschlussprüfern (d.h. dominierende im Vergleich zu nicht dominierenden Abschlussprüfern) Unternehmen dazu motivieren, (mehr) relevante Angaben zu den erwarteten Auswirkungen der erstmaligen Anwendung des neuen IFRS 16 „Leasingverhältnisse“ im Erstanwendungsjahr offenzulegen. Die Ergebnisse deuten darauf hin, dass Mandanten dominierender Abschlussprüfer weniger standardisierte Angaben („boilerplate disclosures“) machen und der Zusammenhang zwischen der Leasingintensität und dem Detaillierungsgrad der Angaben bei diesen Mandanten stärker ist. Die dritte Studie nimmt die Ergebnisse der ersten beiden Studien zum Anlass, die Struktur des Prüfungsmarktes zu untersuchen. Der Fokus liegt hierbei auf der Entwicklung der Konzentration des Abschlussprüfermarktes in Großbritannien und Deutschland rund um eine regulatorische Änderung auf EU-Ebene, die neue Prüfungsanforderungen mit sich bringt, einschließlich der obligatorischen regelmäßigen Rotation von Prüfungsgesellschaften. Während die Ergebnisse auf einen etwa gleichstarken Rückgang der Konzentration der Prüfungsmärkte in beiden Ländern hindeuten, zeigen weitere statistische Tests, dass dieser Rückgang auf nationale Besonderheiten zurückzuführen ist. / This dissertation comprises three papers on financial reporting and auditing. The first two papers examine whether the extent to which the principles-based character of International Financial Reporting Standards (IFRS) allows management to exercise judgement in the preparation of firms’ disclosures is contingent on auditor-type. The first paper explores judgment and estimation uncertainty disclosures (IAS 1) and provides descriptive evidence on an overall increasing trend of disclosure levels and that disclosure levels vary in the cross-section, among other things, by auditor. Inspired by that, the second paper goes a step further and emphasises on the question what type of auditors (i.e., dominant in comparison to non-dominant auditors) motivate firms to provide (more) relevant disclosures on how they expect IFRS 16 – a new standard on leasing – to affect their financial statements in the period of initial application. Results suggest that clients of dominant auditors use less boilerplate disclosures and that the association between leasing intensity and disclosure detail is stronger for those clients. Due to the results of both papers suggesting that the auditor choice matters when firms face judgement in the preparation of their disclosures, the (development of the) audit market structure underlying certain regulations becomes relevant. Thus, the third paper takes these findings of the first two papers as motivation to examine the audit market concentration in the UK and Germany around a regulatory change at the EU level that entails new audit requirements including mandatory audit firm rotation on a regular basis. While aggregate statistics suggest a decrease in market concentration of similar size in both countries, further tests reveal that these decreases are driven by national peculiarities.
