Money is printed by the U.S. Treasury Department and yet economists claim that banks create money. Fully explain how banks creat
Bingel [31]
Most of the money in our economy is created by banks, in the form of bank deposits – the numbers that appear in your account. Banks create new money whenever they make loans. 97% of the money in the economy today exists as bank deposits, whilst just 3% is physical cash. This short video explains:

The money that banks create isn’t the paper money that bears the logo of the government-owned Bank of England. It’s the electronic deposit money that flashes up on the screen when you check your balance at an ATM. Right now, this money (bank deposits) makes up over 97% of all the money in the economy. Only 3% of the money is still in that old-fashioned form of cash that you can touch.

I hope this helps you.

Describe attribution theory, the fundamental attribution error, and self-serving bias. Use examples in your descriptions. How do
MatroZZZ [7]

Answer:

In social psychology, attribution is the process of inferring the causes of events or behaviors. In real life, attribution is something we all do every day, usually without any awareness of the underlying processes and biases that lead to our inferences.

For example, over the course of a typical day, you probably make numerous attributions about your own behavior as well as that of the people around you.

When you get a poor grade on a quiz, you might blame the teacher for not adequately explaining the material, completely dismissing the fact that you didn't study. When a classmate gets a great grade on the same quiz, you might attribute his good performance to luck, neglecting the fact that he has excellent study habits.
