Itô’s Lemma

Grunert, Sandro 10 June 2009 (has links) (PDF)
Itô’s Lemma Ausarbeitung im Rahmen des Seminars "Finanzmathematik", SS 2009 Die Arbeiten des japanischen Mathematikers Kiyosi Itô aus den 1940er Jahren bilden heute die Grundlage der Theorie stochastischer Integration und stochastischer Differentialgleichungen. Die Ausarbeitung beschäftigt sich mit Itô's Kalkül, in dem zunächst das Itô-Integral bezüglich diverser Integratoren bereitgestellt wird, um sich anschließend mit Itô's Lemma bzw. der Itô-Formel als grundlegendes Hilfsmittel stochastischer Integration zu widmen. Am Ende wird ein kurzer Ausblick auf das Black-Scholes-Modell für zeitstetige Finanzmärkte vollzogen. Grundlage für die Ausarbeitung ist das Buch "Risk-Neutral Valuation" von Nicholas H. Bingham und Rüdiger Kiesel.

Essays in International Finance, Energy Economics, and Applied Time Series Econometrics

Boer, Lukas 15 December 2022 (has links)
Diese Dissertation beantwortet verschiedene politikrelevante ökonomische Fragen in den Bereichen Handelspolitik, Geldpolitik, sowie Rohstoffmärkte und Energieökonomik mit Hilfe von strukturellen Vektorautoregressionsmodellen (SVAR). SVARs stellen eine effektive Möglichkeit dar, die Beziehungen zwischen verschiedenen makroökonomischen und/oder Finanzmarkt-Variablen zu modellieren und werden verwendet, um die dynamischen kausalen Effekte von ökonomischen Schocks zu schätzen. Für jede ökonomische Fragestellung wird eine Identifikationsstrategie angewandt, die auf die betrachteten Daten und ihre statistischen Eigenschaften sowie die zugrundeliegenden Annahmen über ökonomische Mechanismen zwischen den betrachteten Zeitreihen zugeschnitten ist. Im Einzelnen besteht diese Dissertation aus vier Kapiteln. In den ersten beiden Kapiteln werden die Auswirkungen von Handelspolitik auf Finanzmärkte und auf die Makroökonomie geschätzt. Das dritte Kapitel liefert einen methodischen Beitrag zur SVAR-Literatur, der in einer Anwendung zu den Effekten von Geldpolitik dargestellt wird. Das letzte Kapitel verlässt die Felder der Handels- und Geldpolitik und wendet sich Rohstoffmärkten und der Energiewirtschaft zu, stützt sich dabei aber ebenfalls auf Zeitreihenmethoden. Es analysiert die Rolle von Metallen in der Energiewende. / This dissertation answers various policy relevant economic questions in the fields of trade policy, monetary policy, and commodity markets and energy economics using structural vector autoregression (SVAR) models. SVARs constitute a parsimonious way to model the relations between different macroeconomic and/or financial variables and they are used to estimate the dynamic causal effects of economic shocks. For each economic question, this dissertation applies an identification strategy that is tailored to the relevant data and its statistical properties as well as the underlying assumptions about economic mechanisms among the regarded time series. Specifically, this dissertation consists of four chapters. The first two chapters estimate the effects of trade policy on financial markets and on the macroeconomy. The third chapter makes a methodological contribution to the SVAR literature in an application to monetary policy shocks. The final chapter moves away from trade and monetary policy to commodity markets and energy economics but also relies on time series methods. It analyzes the role of metals for the clean energy transition.

Empirical investigations into corporate reporting in Europe: A financial market perspective on determinants and consequences of sustainability and digital reporting

Ottenstein, Philipp 07 January 2022 (has links)
This paper-based dissertation comprises five essays dealing with corporate sustainability and digital reporting and is structured in six chapters. The first chapter is the introduction and provides an overview of the structure and aims of the dissertation, lays out the contribution of the work, and introduces the five manuscripts. The second chapter, respectively the first manuscript, deals with the consequences of mandatory sustainability reporting in Europe. Specifically, the study deals with the question whether Directive 2014/95/EU has achieved its objectives of increasing reporting quantity and quality. In the third chapter, the sustainability reports of the largest European firms are analyzed using computer-aided text analysis. This study investigates whether and how external assurance of sustainability reports is beneficial from the viewpoint of report transparency, which is proxied by reporting scope, optimism, and readability. In the fourth chapter, the role of corporate sustainability in the context of M&A transactions is examined, precisely whether sustainability influences the premia paid in M&A transactions. The fifth and the sixth chapters center around the voluntary usage of online financial reporting (OFR) in Europe. While the fifth chapter is concerned with the usage and empirical determinants of OFR, the analysis in the sixth chapter examines the impact of OFR on the financial market, specifically on analyst following and stock liquidity.

Implications of Corporate Social Responsibility on Financial Markets’ Anticipations in the Context of M&A Announcements: International Evidence from the Market for Corporate Control

Jost, Sébastien 09 December 2022 (has links)
Over the last decades, Mergers and Acquisitions (M&A) have become key strategic alternatives to organic growth, enabling firms to expand in new geographies, broaden their product or service portfolios, increase their market power or diversify their business activities, for instance. Historically, although M&A deals have occurred in cyclical patterns, the number of transactions as well the total amount invested have followed an increasing trend. For instance, in 2021, the number of M&A deals conducted worldwide even peaked at an absolute record of 63,215 deals, for a total amount of $5,800 billion, comparable to the annual GDP of a country like Japan. Although the literature on M&A is vast and multi-disciplinarian, the performance of such transactions as well as their influencing factors have remained debated issues. This paper-based dissertation investigates the implications of corporate social responsibility (CSR) on financial markets’ anticipations in the context of M&A announcements. The first manuscript (Manuscript A) corresponds to a literature review on the determinants to financial markets’ reactions around M&A announcements. The second manuscript (Manuscript B) investigates the impact of both acquirers- and targets’ CSR engagements as well as their CSR profiles distance on synergetic gains anticipated by financial markets around M&A announcements. The third manuscript (Manuscript C) focuses on the impact of acquiring firms’ CSR engagement on the accuracy of financial markets’ anticipations with regards to the long-term operating performance of M&A deals. The fourth manuscript (Manuscript D) analyses whether acquirers’ CSR performance impacts M&A premia, since the premia offered to target shareholders contain acquiring managements’ anticipations regarding potential synergetic gains and are by the way critical to the deals’ value creation processes.
