This essay deals with the Working Families Tax Credit (WFTC) which was introduced by the UK government in 1999. The WFTC is a wage subsidy for low income workers that is withdrawn above a certain level of income. To evaluate the impact and outcome of the imposition of this tax credit I will first of all use budget line analysis to predict the likely effects of the reform on labour supply.

Excerpt from the Book
Case (b): individuals who were not working prior to the reform but who choose to work after the credit is introduced. As shown in graph 3, their original (pre-reform) indifference curve (U0B) cuts below the new budget line, indicating that they can now achieve a higher utility level by working (? LFP > 0).
Case (c): individuals who were already working prior to the reform and are on the first kink in the new dashed budget line after the reform. These individuals face offsetting income and substitution effects, implying an ambiguous effect on the hours they choose to work (? H ?). [This case is not shown in any graph.]
Case (d): individuals who were already working prior to the reform and are on the second dashed segment (where the slope is - w) after the reform. These individuals experience a pure income effect as a result of the reform, which implies that they work unambiguously less as a result (? H<0). [This case is not shown in any graph.]
Summary of Chapters
Introduction: Provides an overview of the WFTC policy in the UK and outlines the methodological approach involving budget line analysis and empirical review.
Theoretical Analysis: Details the impact of the WFTC on the budget constraint and categorizes individual responses into six distinct behavioral cases based on utility maximization.
Empirical Evidence and Evaluation: Discusses the findings from studies by Blundell et al. regarding labour participation rates and addresses the methodological difficulties in applying difference-in-differences estimators.
Conclusion: Synthesizes the theoretical and empirical findings, suggesting that while participation effects are positive, the real-world outcome remains complex due to concurrent policy reforms.

Frequently Asked Questions
What is the primary focus of this paper?
The paper investigates the economic effects of the Working Families Tax Credit (WFTC) on the labour supply and work decisions of low-income families in the UK.
What are the central thematic areas covered?
The core themes include theoretical budget line analysis, the impact of wage subsidies on individual work behavior, and the empirical evaluation of government welfare policies.
What is the main goal or research question?
The objective is to evaluate how the imposition of the WFTC influences workforce participation and hours worked among different groups of individuals.
Which scientific methodology is employed?
The paper utilizes theoretical budget line analysis to predict behavior and reviews empirical studies employing the difference-in-differences econometric approach.
What topics are addressed in the main body?
The main body covers the graphical representation of budget sets under different tax brackets, the classification of individuals based on their work-leisure choices, and an empirical assessment of policy outcomes.
Which keywords best characterize the work?
Key terms include WFTC, labour supply, budget line analysis, difference-in-differences, income effect, substitution effect, and labour force participation.
How does the WFTC specifically impact the budget line?
The WFTC shifts the budget line vertically for eligible families and introduces new "kinks" due to the credit withdrawal rate as earnings increase.
Why was the difference-in-differences approach difficult to apply for this specific policy?
The approach faced challenges because the UK government implemented other concurrent reforms, such as child allowance adjustments, which complicated the selection of a clean control group and led to potential estimation biases.
