The Economics of Air Transportation: Theory and Quantitative Analyses

(Die Ökonomie des Luftverkehrs: Theorie und quantitative Analysen)

Seminar Content/ Inhalt:

1) This course covers the economics of air transport (airports, airlines and air traffic controls) and the quantitative practices used in the industry. 

Dieser Kurs umfasst die Wirtschaftlichkeit des Luftverkehrs (Flughäfen, Fluggesellschaften und Flugverkehrskontrollen) und die quantitativen Praktiken, die in der Industrie verwendet werden.

2) The study of production and cost function lays the basis for answering practical policy questions including governance structure and competition in the industry. 

Das Studium der Produktions- und Kostenfunktion legt die Grundlage für die Beantwortung praktischer politischer Fragen wie Governance-Struktur und Wettbewerb in der Branche.

3) An extensive literature review serves as background for understanding the main policy issues of the air transport industry( like horizontal and vertical organization of the industry, the organization of the value chain of airlines, airports, and ATC, and the role of governments in the industry. 

Eine umfassende Literaturrecherche dient als Hintergrund für das Verständnis der wichtigsten politischen Fragen der Luftverkehrsbranche (wie die horizontale und vertikale Organisation der Industrie, die Organisation der Wertschöpfungskette von Fluggesellschaften, Flughäfen und ATC, und die Rolle der Regierungen in der Industrie.

4) A special focus will then be given to airports, where an already existing database will be updated and used in various policy oriented case studies.

Ein besonderer Fokus wird dann auf Flughäfen gelegt, wo eine bereits vorhandene Datenbank in verschiedenen politikorientierten Fallstudien aktualisiert und genutzt wird.

Learning Outcomes

In this seminar, the students will 

-understand the economics of airports, airlines and ATC 

-be able to work with a database including financial, traffic and technical variables estimate cost and/or production functions of airports as a basis for policy discussion 

-estimate demand functions for air transport and generate pricing policies 

-analyze the difficulties regional airports face with regard to scale and cost disadvantages 

-understand the role of non-aviation services at main airports 

-write a term paper on a policy issue with quantitative applications based on a key publication.

Abstract

Search databases typically contain only abstracts. It is vital to

write a complete but concise (150 words) description of your work

to entice potential readers. First impressions count in research too.

I Motivation: Why do we care?

I Problem statement: What problem are you trying to solve?

What is the scope of your work?

I Approach: How did you go about solving or making progress

on the problem?

I Results: What’s the answer?

I Conclusions: What are the implications of your answer?

Introduction

I What is the subject of the study

I What do we already know about the subject (literature

review)

I What is the innovation of the study

I What is the purpose of the study (working hypothesis)

I Outline of the paper

Methods

I How was the data analyzed

I Present underlying economic model/theory

I Present econometric/statistical estimation method

I Allows reader to judge validity of the study and its findings

Data

I Describe data and its quality

I How was the data sample selected

I Descriptive statistics such as

. time period

. number of observations, data frequency

. mean, median

. min, max, standard deviation

. skewness, kurtosis, Jarque–Bera statistic

. time series plots, histogram

I Allows reader to judge whether sample is biased or to evaluate

possible impacts of outliers, for example

Results

I Organize material and present results

I Use tables, figures (but prefer visual presentation)

I Tables, figures should supplement (and not duplicate) the text

I Discuss results

. Do the results support or do they contradict economic theory

. Compare to previous research

Conclusion

I Summary of what has been done and what has been found

I Draw conclusions about the problem studied

I Limitations of study (assist reader in judging validity of

findings)

I Suggest avenues for future research

References

I List papers referenced in the study (not all the papers you

ever read in your life)
