The Role of Financial Markets
• Insurance companies and individual communities/families have traditionally helped each other to share risks
• Markets make risk-sharing more efficient
– Diversifiable risks vanish– Non-diversifiable risks are reallocated
• Recent example: earthquake bonds by Walt Disney in Japan

Financial Engineering

Short-Selling
• When price of an asset is expected to fall– First: borrow and sell an asset (get $$)– Then: buy back and return the asset (pay $)
– If price fell in the mean time: Profit $ = $$ – $– The lender must be compensated for dividends received (lease-rate)
• Example: short-sell IBM stock for 90 days
Table 1.4 Cash flows associated with short-selling a share of IBM for90 days. S0 and S90 are the share prices on days 0 and 90. Note that the short-seller must pay the dividend, D, to the share lender.

Short-Selling (cont’d)
• Why short-sell?
– Speculation– Financing– Hedging
• Credit risk in short-selling
– Collateral and “haircut”
• Interest received from lender on collateral
– Scarcity decreases the interest rate– Repo rate in bond markets– Short rebate in the stock market

Basic Transactions
• Buying and selling a financial asset
– Brokers: commissions– Market-makers: bid-ask (offer) spread
• Example: Buy and sell 100 shares of XYZ
– XYZ: bid = $49.75, offer = $50, commission = $15– Buy: (100 x $50) + $15 = $5,015– Sell: (100 x $49.75) – $15 = $4,960– Transaction cost: $5015 – $4,960 = $55
