go to the st. louis federal reserve fred database, and find data on assets less liabilities, i.e. bank capital (ralacbm027sbog), and total assets of commercial banks(tlaacbm027sbog). starting in january 1973 until december 2021, using the fred graphing tool, calculate the bank leverage ratio and create a line graph of the leverage ratio over this sample (include the graph you created with your submission). given the path of bank leverage over time, what can you conclude about moral hazard in the banking system over the time period considered?
