1. In a scenario of perfect capital mobility, capital flows respond quickly to differences in interest rates between countries, influencing both domestic and foreign investments.
2. Perfect capital mobility implies that any changes in domestic monetary policy can be quickly offset by capital flows, potentially limiting the effectiveness of such policies.
3. Under perfect capital mobility, the balance of payments must adjust to maintain equilibrium, as capital will flow towards countries offering higher returns.
4. Perfect capital mobility is often associated with open economies, where trade barriers are minimal and international financial markets operate efficiently.
5. Real-world examples of perfect capital mobility are rare; however, many advanced economies exhibit near-perfect conditions due to liberalized financial markets.

Review Questions

• How does perfect capital mobility influence interest rates and investment decisions in an economy?
  • Perfect capital mobility allows capital to flow freely between countries in search of higher returns. This means that if interest rates rise in one country compared to another, investors will quickly move their funds to take advantage of the better returns. Consequently, this can lead to lower domestic interest rates in the country losing capital and potentially decreased domestic investment as funds exit.
• Discuss the implications of perfect capital mobility for monetary policy effectiveness in an open economy.
  • In an environment of perfect capital mobility, changes in domestic monetary policy can be quickly countered by international capital movements. For instance, if a central bank lowers interest rates to stimulate growth, it may lead to capital outflows as investors seek better returns elsewhere. This undermines the intended effect of the policy, making it challenging for policymakers to achieve their economic objectives without considering global financial dynamics.
• Evaluate the conditions under which perfect capital mobility might fail and its potential impact on global economic stability.
  • Perfect capital mobility might fail due to factors like political instability, sudden changes in government policies, or financial crises that create uncertainty. When these conditions arise, investors may restrict their capital movements, leading to market inefficiencies and potential imbalances. Such disruptions can trigger volatility in exchange rates and affect global economic stability by causing sudden shifts in investment patterns and altering trade balances among nations.
