Overcoming original sin: Shedding new light on uneven progress
研究了新兴市场经济体通过发行本币债券和吸引外资参与国内债券市场来克服原罪（无法以本币在国外借款）的进展，发现进展缓慢且不均衡，制度发展是关键因素。
Abstract This article examines sovereign bond markets to assess the current state of Original Sin, the inability of a country to borrow (abroad) in its own currency. We present a synthesis of different strands of the literature using a new, tailored dataset. We find that major emerging market economies (EMEs) have made progress towards overcoming original sin by issuing more government bonds in local currency while promoting foreign participation in domestic bond markets; this went hand in hand with rising exposure to EME currencies among foreign investors. In panel regressions, we show that country-specific variables played a role alongside global push factors. However, progress has been slow and uneven, with a key role for institutional development. Progress is most evident among major EMEs, and stronger for sovereigns than for other issuers. Reducing reliance on foreign currency borrowing implies a greater role for investors whose sensitivity to currency risk can make capital flows more volatile—reintroducing the problem in a different guise, as original sin redux.
