The main thesis in this manuscript is that a social choice theory based on aggregating individual preferences and values is insufficient to confront the social choices that today’s world is facing. It is defended in here that institutions play a critical role in any social choice, and that the...

The paper introduces foreign exchange interventions (FXIs) into a standard New-Keynesian small open economy model. It solves for the optimal FXI policy, suggests an implementable policy rule, and studies the transmission mechanism of FXIs. Relying on the portfolio balance channel, deviations...

Two assertions about exchange rate regimes circulate with some frequency in policy circles. The first, the hypothesis of the excluded middle, holds that authorities must either choose perfectly floating exchange rates (preferably anchored by an inflation target for the central bank) or a hard...

Many emerging market countries have suffered financial crises. One view blames soft pegs for these crises. Adherents to that view suggest that countries move to corner solutions--hard pegs or floating exchange rates. We analyze the behavior of exchange rates, reserves, and interest rates to...

The unprecedented financial and economic world present turmoil is dangerously covering the Europe and Japan, coming from the USA and being more painful than the economic downturn of the ‘80s. A massive decrease of trust and confidence is also perceived by consumers and business alike, and...

The choice of an appropriate exchange rate regime has been a subject of ongoing debate in international economics. The majority of African countries are small open economies and thus where the choice of the exchange rate regime is an important policy issue. Aside from factors such as interest...

This note reviews the theories as to why financial crises spill over across national boundaries. We discuss alternative frameworks ranging from bilateral trade links to more complex financial interconnections via banks and other investors. We review the evidence on which channels of contagion...

The preceding sections have predominantly focused on the antecedents of financial crises. Namely, the emphasis has been on the ability of a variety of indicators, including the credit ratings, to anticipate crises and characterize the extent to which a country is vulnerable. An application of...

Testing the international Trilemma traditionally relies on discretely classified exchange rate regimes. This simplification limits the implications drawn for middle-ground policies like managed floats or basket pegs, and inhibits inference on the empirical shape of the exchange rate stability --...
