Study Notes
Learning Outcomes
- Discuss the relevance of Rawlsian Justice in Fairness theory within South Africa's constitutional political economy.
- Evaluate the Median Voter Theorem and its implications on voting systems.
- Explain the Impossibility Theorem and its effects on social choice.
- Assess Logrolling (vote trading) and its potential to enhance Majority Voting systems.
- Analyze the self-interest maximization behaviors of politicians and bureaucrats, and their impacts on majority voting.
- Explore the origins and consequences of rent-seeking behavior.
Social Choice and Political Allocation of Resources
- Mixed economies include both private and public sectors.
- Private markets leverage the invisible hand for resource coordination.
- In the public sector, resource allocation is determined through voting and tax rates act as pricing mechanisms.
- Individual choices are transformed into social choices using various voting rules.
Rawlsian Unanimity Rule (RUR)
- Requires 100% agreement for decision-making.
- Targets the poorest, enhancing collective welfare as it follows a MaxMin strategy.
- RUR is the only Pareto efficient rule but decision-making costs are high, allowing minority vetoes.
Ordinary Majority Voting Rule (MVR)
- Direct democracy necessitates 50% + 1 vote for a proposal.
- Median Voter Theorem (MVT) posits that the median voter's preferences minimize collective welfare loss.
- Politicians may prioritize vote maximization, often influenced by personal and special interests rather than the public good.
Median Voter Theorem (MVT) in Action
- Example with National Health Insurance (NHI) highlights the importance of identifying the median voter.
- A preference for a 17.5% VAT indicates broad support across the voter distribution.
Social Choice in Coalition Government
- Surveys reveal citizen preferences for policy representatives, indicating varied support for coalitions among different party voters.
Arrow’s Impossibility Theorem (AIT)
- AIT asserts no social choice rule can produce consistent outcomes.
- Key assumptions include rational voter behavior, single-peaked preferences, and the independence of irrelevant alternatives.
- Voting paradox illustrated through intransitive preferences despite majority support.
Intensity of Preferences: Logrolling
- Majority rule may ignore preference intensity leading to suboptimal societal outcomes.
- Logrolling can occur through vote trading, fostering majority support without undermining minority preferences.
Optimal Voting Rule (OVR) by Tullock & Buchanan
- Suggests a potential rule outperforming dictatorship or majority rule by considering external costs and decision-making costs.
- Higher external costs necessitate greater consensus to prevent inefficient outcomes.
Government Failure
- Governments fail due to corruption, bureaucratic capture, and joint elite behavior.
- Politicians target special interests to maximize votes, often misleading costs leading to fiscal illusions and implicit logrolling.
- Result is an oversupply of unpopular public goods and significant economic inefficiencies.
Bureaucratic Behavior
- Bureaucrats aim to maximize budgets and sizes of their departments, resulting in X-inefficiency.
- Principal-agent problem occurs when bureaucrats’ goals diverge from citizens’ interests, leading to public good oversupply and rent-seeking behavior.
Price Gorging Example
- Eskom's mismanagement, including significant overpayments and corruption, exemplifies bureaucratic X-inefficiency and rent-seeking at the expense of societal welfare.### Opaque Procurement and Corruption
- Opaque procurement processes facilitate rent-seeking behaviors and encourage inflated tender prices.
- Corruption thrives in environments where transparency is lacking, impacting public resources and efficiency.
Transnet Financial Overview
- Transnet incurred a loss of nearly R6 billion in 2023.
- Executives at Transnet received over R87 million in salaries and benefits despite the organization’s financial struggles.
- There exists a disconnect between executive compensation and organizational performance, raising concerns about accountability and governance.
Economic Implications
- Public choice theory serves as a lens to analyze governmental economic behavior and policy motivations.
- Understanding who benefits from certain policies and who bears the costs is crucial in evaluating public sector decisions.
- The potential for real-world application of theoretical concepts may arise in examinations, utilizing case studies or data from credible reports like the Zondo or Nugent Commissions.
Exam Preparation Tips
- Focus on comprehension rather than rote memorization of concepts.
- Prepare to apply theoretical frameworks during assessments, recognizing the empirical implications of policies and executive actions.
