The case study discusses the lending club business model, which allows members to indirectly invest in promissory notes issued by the club through online peer-to-peer lending. The company has entered into an arrangement with WebBank, enabling it to provide beneficial interest rates to customers across operating countries. The profitability of the company is determined by factors such as product and services, return on loan, financial structure, and customer satisfaction. The peer-to-peer model provides higher returns compared to other models due to the absence of intermediaries between lenders and borrowers. The study also highlights the importance of secondary market liquidity in reducing transaction costs and risk premium, which enables companies to generate higher returns on investment.
