“…Central banks make intensive use of structured databases to carry out their functions, whether in the banking supervision, financial stability, or monetary policy domains, to mention the core ones. 1 Some examples of individual data are firms' balance sheets (see, e.g., [51] or [6]), information relating to the volume of credit granted by financial institutions to individuals and firms, or the data relating to agents' financial decisions (see, e.g., [5]). In the area of macroeconomics, the main source of information tends to be the national accounts or the respective central bank sources, although a great deal of other information on the economic and financial situation is also published by other bodies: e.g., social security data, payroll employment data (Bureau of Labor Statistics), stock prices (Bloomberg), and house prices (real estate advertising web platforms).…”
