Summary The global financial crisis of 2007-2009 is considered the most impactful since the Great Depression, which began in 1929. Various factors are responsible for the crisis, including improper monetary policy, unrestrained use of financial instruments, and lack of transparency and adequate governance in numerous financial or banking firms. Regulators failed to maintain balance and protect consumers of the financial system. This was evident in their approach to top executives. Further, unethical fiscal practices that resulted in misinformed or exploited consumers and investors led to the collapse. The case-study examines principal theories and the reasoning behind market intervention for the purpose of consumer prevention in the post-crisis era. Regulators are faced with the challenge of balancing consumer protection with business interests. A non-interventionist approach has no government involvement and promotes competition, the disclosure of information, caveat emptor , and private regulation mechanisms. It is founded on the belief of the belief in free-market efficacy. Human beings are considered rational economic actors that maximize self-interest and utility, but it is assumed that there is a free flow of information to make adequate decisions. Also, behavior and psychology show that people can easily make irrational or erratic decisions based on a lack of self-control, cognitive biases, and heuristics that are detrimental to their welfare. An interventionist approach advocates for heavy government regulatory involvement aimed at continuous monitoring of seller and supplier activities with the purpose of protecting consumer interests. This regulation includes bans and limits, including fiscal activity such as risk-sharing, the conduct of business, and product quality. The strict approach is founded in the study of economic behavior that disproves a rational choice theory and is based on the complex pandemonium of sociological, psychological, cultural, and environmental factors. Another justification for consumer protection is the lack of open access information that is fundamental to a proper free-market system. Information may not be provided due to associated costs and limits to distribution. At times, information is purposefully concealed or misrepresented for deception purposes leading to fraud. Also, the lack of information about quality creates a “market for lemons,” which is relevant to not only goods but services. Information gives consumers the ability to evaluate products, and restricted access to accurate or complete data severely distorts the balance between consumer and supplier. The concepts of morality are relevant as capitalism promotes self-interest and profit, which leads to improper conduct and violation of ethical norms. An interventionist approach is based on paternalism, which is essentially interference with a person’s liberty using the premise that it benefits the consumer’s welfare and interests. Once again, it is a response to the fact that humans are inertly self-destructive and irrational in their behaviors. However, paternalism can lead to the state gaining too much power through coercion. Libertarian paternalism was developed to face criticism and become less intrusive, operating through guiding influe
