A market economy is when private businesses are in complete control of the economy with no government intervention. this can be seen in the late 1800s when capitalism had little regulation in both america and the uk. A mixed economy is going to be the one you see most in the modern world, where both government and private businesses have power in the economy. the businesses usually have the products and distribute them while the government regulates what the companies can do. for example, child labor laws, minimum wage, and standard working conditions are all what the government has put in place to regulate private businesses. hope this helped!
