From here the article weakly illustrates the theory in the employment of minorities, and even attempts to theoretically quantify the cost of dishonesty in the market place. Things again get interesting when Akerlof discusses the lemon theory in credit markets found in underdeveloped countries, primarily focusing on India. The article found that if
