The correct questions are:
1) Financial regulation stimulates competition practices and prohibits the creation of monopolies, except when authorized by the government.
3) The regulatory apparatus forces companies to follow best accounting practices and encourages transparency. This reduces cases of corruption and tax evasion.
4) Regulation stimulates competition between firms. In a competitive market firms the vector of competition among firms is the price. This stimulus to competition is good for the market and for the consumer. Efficient firms charge a lower price, benefiting the consumer. Inefficient firms are eliminated from the market.
