### Summary
- This paper examines the effects of capital controls on asset prices.
- A closed-form valuation model by Eun and Janakirimanan (1986) is extended to analyze the impact of three restrictions on international portfolio investment:
  - a percentage quantity constraint on the amount of foreign securities a domestic resident may hold in her portfolio;
  - a constraint on the absolute amount of foreign securities a domestic resident may hold;
  - a percentage tax on the domestic purchase price of a foreign security.
- Comparative statics and numerical analysis are used to reveal the effects of these distortions on domestic and world equilibrium prices.

### Methods and Model
- Extension of a closed-form valuation model (Eun and Janakirimanan, 1986).
- Use of comparative statics.
- Use of numerical analysis to determine impacts on equilibrium prices.

### Key Findings
- The paper characterizes how three types of restrictions (percentage portfolio constraint, absolute quantity constraint, and percentage tax on purchase price) distort international portfolio investment decisions.
- These distortions affect both domestic and world equilibrium prices (effects detailed through comparative statics and numerical examples in the paper).
