Co-movements between major and emerging market stock prices around the
1987 crash reveal a relationship between foreign entry barriers and s
tock price transmission. For most countries, individual market return
volatility and price spillovers among markets increase immediately aft
er the crash. However, in markets with stiff entry barriers, volatilit
y rises but there are no price spillovers; in those cases, the premium
on closed-end country fund shares increases. This suggests that large
transaction costs associated with international arbitrage provide a b
arrier to large price signals. The evidence that several emerging-mark
et countries are poorly integrated financially with the industrialized
countries has important macroeconomic welfare implications.
