Plain-text version
In a two-good world, utility is u(x₁,x₂)=x₁ x₂. Each good's market price is Rupee 1 and disposable income is Rupees 100. If the price of X₂ is doubled keeping the price of X₁ unchanged, then the associated Compensating Variation is Rupees (*rounded off to one decimal place*).
Also written as: In a two-good world, utility is u(x_1,x_2)=x_1 x_2. Each good's market price is Rupee 1 and disposable income is Rupees 100. If the price of X_2 is doubled keeping the price of X_1 unchanged, then the associated Compensating Variation is Rupees (*rounded off to one decimal place*).
