This paper assesses the extent of regional financial integration in the Caribbean Community (CARICOM) by analyzing equity prices in the region and rigidity of external financing constraints. The results are presented in a cross-regional perspective. The Caribbean stock markets are not as well integrated as one would expect from the extent of cross-listing and importance of regional banking groups: price differentials of cross-listed stocks reach an average of 5 percent. Auto-Regressive models suggest that these price differentials are only slowly arbitraged away, with half-lives exceeding 7 worked days, even when looking only at large arbitrage opportunities (using a Threshold Auto-Regressive model). A speculative methodology using macroeconomic data seems to confirm these findings. A strong mean reversion of the current account (respectively regional trade imbalances) is interpreted, following Obstfeld and Taylor (2004), as a lack of ways to finance current account deficits, i.e. a lack of global (respectively regional) financial integration. The region appears to be much less integrated than the EU15 or the ASEAN+3 groups, although it fares well compared to other LDCs.

assess the extent of financial integration for emerging markets is less common. Levy Yeyati et al. (2006) estimate the Auto-Regressive dynamics (AR) of the cross-market premium, i.e. the premium between the prices of two identical stocks traded in two different markets. Since it is known that standard AR regressions underestimate convergence speeds in presence of non-linearities, the authors also use of a Threshold Auto-Regressive model (TAR). They use data of stocks listed in several emerging markets that are also cross-listed in the U.S., and estimate that the
