An Analysis of the Effects of Recent Changes in the Exchange Rate and the Terms of Trade on the Level and Composition of Economic Activity

Over the eighteen-month period ending June 1986, the Australian economy experienced two major shocks: a nominal devaluation of the $A of some 28 per cent and a terms of trade decline of some 16 per cent. The effects of these influences are examined using the ORANI model of the Australian economy. The effects of the devaluation on selected macroeconomic variables and key sectoral variables are presented for various degrees of wage indexation. Effects on quota rents are calculated and compared with actual outcomes. The terms of trade decline has an adverse impact on the balance of trade and in order to offset this impact while maintaining aggregate employment demand the model calculates that both real wages and real absorption would need to be around 4 per cent less than the values they would otherwise take.     

An explanation of why shareholders' losses are so large after drug recalls

Recent studies show firms suffering drug recalls experience security losses many times larger than any reasonable measure of their direct cost. We discover that the implied standard deviation of stock returns from the Black-Scholes option pricing model significantly increases after a drug recall. The implied standard deviation provides a good proxy for the stock's ex ante beta. The higher systematic risk after a product recall must raise the discount rate used by investors. After a recall, stock prices are reduced in line with the lower expected future earnings and are further reduced because of a higher discount rate.
