The traditional approach to the central bank's lender of last resort function emphasizes the trade-off between being too ‘tough’, and thus increasing the likelihood that the failure of a single bank hampers the confidence in the whole banking system, and being too ‘soft’, thereby creating incentives for banks to take on excessive risk. In contrast with this view, we show that a central bank, by announcing and committing ex-ante to bail out insolvent institutions in times of adverse macroeconomic conditions, can create a risk-reducing ‘value effect’ that outweighs the moral hazard component of the policy, and thus lowers bank risk.

In the 1990s, Latin American banking sectors experienced an accelerated process of concentration and foreign penetration that prompted diverse views regarding its implications for the competitive behavior of banks and the financial stability of the system. In this paper, we examine these issues exploiting a rich bank-level database for eight Latin American countries. We find that, while increased concentration did not weaken banking competition within the region, foreign penetration appears to have led to a less competitive industry. Moreover, we find that bank risk has been negatively associated with competition which, coupled with the previous finding, explains the positive link between banking sector stability and foreign penetration revealed by the data.

This paper takes advantage of the fact that some stocks trade both in domestic and international markets to characterize the degree of international financial integration. The paper argues that the cross-market premium (the ratio between the domestic and the international market price of cross-listed stocks) provides a valuable measure of international financial integration and the effectiveness of capital controls. Using autoregressive (AR) models to estimate convergence speeds and non-linear threshold autoregressive (TAR) models to identify non-arbitrage bands, the paper shows that price deviations across markets are rapidly arbitraged away and bands are narrow, particularly so for liquid stocks. The paper also shows that regulations on cross-border capital flows effectively segment domestic markets. As expected, the effects of both types of capital controls are asymmetric but in the opposite direction: controls on outflows induce positive premia, while controls on inflows generate negative premia. Both vary with the intensity of capital controls.

We study the relationship between exchange rate regimes and economic growth for a sample of 183 countries over the post-Bretton Woods period, using a new de facto classification of regimes based on the actual behavior of the relevant macroeconomic variables. In contrast with previous studies, we find that, for developing countries, less flexible exchange rate regimes are associated with slower growth, as well as with greater output volatility. For industrial countries, regimes do not appear to have any significant impact on growth. The results are robust to endogeneity corrections and a number of alternative specifications borrowed from the growth literature.

We study how the growth of exchange-traded funds (ETFs) affects the sensitivity of international capital flows to the global financial cycle. Using comprehensive fund-level data on investor flows, we show that their sensitivity to global financial conditions for equity (bond) ETFs is 2.5 (2.25) times higher than for equity (bond) mutual funds. This higher sensitivity can be directly linked to ETFs underlying shorter-trading-horizon clientele that trades more often in response to shocks. Using country-level data, we find that where ETFs hold a larger share of financial assets, equity inflows and prices become more sensitive to global risk.
