Foreign Exchange Intervention in Emerging Markets: A Survey of Empirical Studies

Nowadays foreign exchange interventions occur in emerging market economies, whereas empirical studies on interventions mainly refer to advanced economies. However, interventions in emerging markets are different from those in advanced economies: they occur ‘regularly’ and central banks have considerable leverage, derived from relatively high reserves, some non‐sterilisation, the central bank’s information advantage and capital controls. Consequently, these interventions often successfully impact the level and volatility of exchange rates. Nevertheless, more research on interventions in emerging markets is needed analysing the influence of heterogeneous institutional circumstances, examining the role of central bank communication and using high‐frequency data.     

Are Foreign Institutional Investors Good for Emerging Markets?

Portfolio flows channelled via institutional investors were the most dynamic capital flows to emerging markets in the 1990s. We use an asymmetric information framework to derive five propositions about the effects of the activities of foreign institutional investors on emerging markets. We confront these propositions with existing empirical evidence on the financial sector of emerging markets and conclude that institutional investors do not automatically generate benefits for emerging markets. Therefore, capital account and financial market liberalisation needs to be accompanied by careful regulation.     

Overconfidence as a social bias: Experimental evidence

The overconfidence bias is discussed extensively in economic studies, yet fails to hold experimentally once monetary incentives and feedback are implemented. We consider overconfidence as a social bias. For a simple real effort task, we show that, individually, economic conditions effectively prevent overconfidence. By contrast, the introduction of a very basic, purely observational social setting fosters overconfident self-assessments. Additionally, observing others’ actions effectively eliminates underconfidence compared to the individual setting.
