Apparently mapped out on a napkin during a dinner with the journalist Jude Wanniski in 1974, the Laffer curve - called after Arthur B. Laffer who is widely seen as “The father of supply-side economics” - has become one of the most controversially discussed topics in terms of tax politics since published by the before mentioned journalist in 1978.
As taxes are the most important income source for all governments, politicians around the globe are trying to determine the highest realizable tax revenue. Therefore they are using whatever they can to justify their decisions and the Laffer curve was and is used since the 80’s to promote tax cuts as a way to increase tax revenue. The objective of this work is to analyse a tool that is consistently used to establish decisions that sound great in the ears of potential voters but that is – at least at first glance – not very convincing in its approach as there are obvious conceptual limitations. Ultimately the question Laffer curve is suited to increase the total tax revenue by cutting tax rates.

Objectives and Research Focus
This work aims to evaluate the theoretical framework of the Laffer curve, specifically investigating whether reducing tax rates can effectively lead to an increase in total government tax revenue. It challenges the assumption that tax cuts universally generate higher income by highlighting conceptual limitations and practical complexities.
- Theoretical analysis of the Laffer curve and the role of price elasticity.
- Case study evaluation of the Reagan-era tax cuts in the 1980s.
- Case study assessment of the tobacco tax program in Germany.
- Critical examination of tax revenue dynamics and taxpayer behavioral responses.
Excerpt from the Book
2.1 The theory behind the graph
The Laffer curve is a very simple visualization of the dependency of tax rate and tax revenue or government revenue as called in figure 1. Obviously there are two fixed points at 0% and 100% tax rates were the according revenue would be Zero. If there is no tax imposed – as with 0% tax rate – there cannot be any revenue. In the other case – tax rate at 100% - no one would work or buy something. Economy would come to a full stop and there would not be any revenue either.
Laffer imposes that those two points on the tax rate-axis are connected with a curve lying on the positive side of the government revenue-axis of the graph. Like at all curves there is a maximum point that describes the point where the tax revenue would be as high as it could get. This point is related to a point on the tax rate-axis that shows the according tax rate (t*) to realize this maximum tax revenue.
Looking at the graph it is easy to understand that a tax cut can only lead to a higher tax revenue as long as the actual tax rate is on the right side of t*. Meaning that the point of maximum revenue has been overstepped and the tax revenue is therefore decreasing.
Summary of Chapters
1. Introduction: Presents the origins of the Laffer curve and outlines the primary objectives of the study.
2. The Laffer-curve: Explains the underlying theory of the Laffer curve, the concept of elasticity, and identifies potential inconsistencies.
3. Case study: Reagan Tax Cuts in the early 1980s: Analyzes the US tax policy in the 1980s to determine if the theory held true for different taxpayer groups.
4. Case study: Tobacco tax program in Germany: Investigates the German tobacco tax history and evaluates how tax increases affect consumption and revenue.
5. Conclusion: Summarizes the findings and clarifies that the Laffer curve is not a universal tool and requires segment-specific analysis.

Frequently Asked Questions
What is the fundamental focus of this study?
The study examines the validity of the Laffer curve, specifically whether lowering tax rates leads to higher total government revenue.
What are the primary thematic areas covered?
The research covers fiscal policy, the relationship between tax rates and government income, the concept of economic elasticity, and practical case studies in the US and Germany.
What is the main research question?
The core question is whether the Laffer curve is a suitable tool for increasing tax revenues through tax cuts in real-world scenarios.
Which scientific methodology is employed?
The authors use an analytical approach, reviewing economic theory (elasticity) and performing comparative case studies based on historical tax and revenue data.
What is addressed in the main body?
The main body discusses the theoretical construction of the Laffer curve, followed by two detailed case studies analyzing the Reagan administration's tax reforms and the German tobacco tax system.
Which keywords best characterize this work?
Key terms include Laffer curve, elasticity, tax policy, supply-side economics, and government tax revenue.
What did the analysis of the Reagan tax cuts reveal?
The study found that tax outcomes varied significantly by income group, showing that the "Laffer effect" did not universally apply to all taxpayers as expected.
What conclusion does the study reach regarding tobacco taxes in Germany?
It concludes that while tax segmentation can influence consumer behavior, the relationship between tax rates and revenue is complex and influenced by the availability of substitutes.
