Essay 7

Basic setup:

A farmer’s harvest will be worth £200 if she can borrow £100 worth of fertilizer, and £0 otherwise.

The fertilizer needs to be applied now and harvest will take place in six months’ time. 

There are N>100 other people in the village, each of whom has saved £1.

Essay 7 Question aIs there a role for a financial system in this economy? Briefly describe a few types of financial arrangements that you might observe in this economy.

Without financial systems: Borrow (<)1$ from 100 (+) villagers

Possible, but costly

Financial system allows farmer easier access to savings of villagers

If financial markets present: Could issue bonds or stocks If financial intermediaries present: villagers deposit savings

and bank gives loan to farmer

Essay 7 Question b

Suppose an enterprising villager starts a new bank (with 0 capital), collects all of the villagers’ savings, and lends the £100 to the farmer. How will this bank’s balance sheet look like?

What does a balance sheet consist of? Assets = Liabilities (+equity)

Assets Liabilities+ Equity

Loans 100$ Deposits: N$

Reserves N$-100$ Equity

Essay 7 Question c

Suppose now that each of the savers faces some chance that there will be an emergency such as they will absolutely need access to their £1 three months from now. Is there still a role for a financial system?

Without financial markets - will the farmer be able to finance his investment?

What about if we only have financial markets?

Essay 7 Question d

Suppose that the probability that any investor faces the emergency is p. What is the minimum value of N such that the financial system can viably allow the farmer to buy the fertilizer?

Pool of savings: N*1$ But p*N*1$ will need to be withdrawn in expectation Hence the savings to reach the farmer will be (1-p)N$ Needs to be >=100$ => need N>100(1-p) Similar with financial intermediaries: need to keep p*N*1$ as

reserves
