uppose that The Elasticity of Imports in the USA in the short Run is 0.5 The Elasticity of Imports in Japan in the short Run is -0.3 The Elasticity of Imports in the USA in the long Run is 1.2 According to the Elasticities approach to the Current Account Balance, if the Exchange Rate goes from Yen=$1/100 to Yen=$1/50 ...

The Current Account Balance in the US will deteriorate in the short run and in the long run

The Current Account Balance in the US will deteriorate in the short run, and improve in the long run

The Current Account Balance in the US will improve in the short run and in the long run

The Current Account Balance in the US will deteriorate in the short run, and improve in the long run as long as the elasticity of imports in Japan is strictly more than -0.2

Solutions

Expert Solution

We are given that elasticity of Imports in the USA in the short Run is 0.5 and in the long Run it is 1.2  The yen is depreciating and so dollar is appreciating. This implies that price of dollar (relative) will increase and this will reduce the quantity demanded of imports in the short run (being inelastic at 0.5) and will increase in the long run (as demand is elastic at 1.2). Hence current account will experience a deficit in the short run but an improvement in the long run. When demand is elastic, price rises reduces revenue and so import bill will fall in long run and rise in short run. This depends upon the elasticity of Imports in Japan because yen is depreciating so yen will also experience an deficit in the short run.

Correct choice is The Current Account Balance in the US will deteriorate in the short run, and improve in the long run as long as the elasticity of imports in Japan is strictly more than -0.2

a) Price elasticity of demand for cigarettes is -0.5 in the short-run. Currently, the price per pack of cigarettes is $5.50 in Louisiana. $0.86 of this price is state tax and about $1 of the price is federal tax. Each year 350 million packs of cigarettes are sold in Louisiana. If the state government increases the state tax to $1.08 per pack, what would be the new state tax receipts from cigarettes after this tax increase? b) How would your...

If the short run price elasticity of demand is -.20 how much will a 10 percent increase in the price of oil decrease the quantity demanded? Given this price elasticity will the total revenue received by oil producers increase or decrease when oil prices rise? Explain why the price elasticity of demand for oil more elastic in the long run. Draw your long run demand curve.

An economy consists of two regions, the North and the South. The short-run elasticity of labor demand in each region is -0.5. Labor supply is perfectly inelastic within both regions. The labor market is initially in an economywide equilibrium, with 600,000 people employed in the North and 400,000 people in the South at wage of $15 per hour. Suddenly, 20,000 people immigrate from abroad and initially settle in the South. They possessed the same skills as the native residents and...

A For many products, long-run supply is likely to be more price elastic than short-run supply. B For products that can be recycled, long-run supply is likely to be more price elastic than short-run supply. C For many products, long-run supply is likely to be less price elastic than short-run supply. D Both a) and b) are generally true, but c) is generally...
