Finance and Financial Intermediation. A Modern Treatment of Money, Credit, and Banking

The financial system is a densely interconnected network of financial intermediaries, facilitators, and markets that serves three major purposes: allocating capital, sharing risks, and facilitating intertemporal trade. Asset prices are an important mechanism in each of these phenomena. Capital allocation, whether through loans or other forms of investment, can vary both across sectors-at the broadest, manufactures, agriculture, and services-and within sectors, for example different firms. The risk that various investors are willing to take reflects their financial position and alternative opportunities. Risk and asset allocation are also influenced by whether money, and especially its expenditure, is more important now or in the future. These decisions are all influenced by governmental policies. When there are mismatches, the results include financial meltdowns, fiscal deficits, sovereign debt, default and debt crises.
