Five Years After: European Union Membership and Macro-Financial Stability in the New Member States
Description: The proximity of the European Union, the prospect of membership, and actual entry by the New Member States (NMS) increased economic and financial integration in the region, leading to fast economic growth based on sizeable capital inflows. EU membership helped in developing sound macroeconomic and financial stability frameworks in the NMS. However, these frameworks remain work in progress and as such could not safeguard against private sector exuberance or risky policies, especially in the face of an unprecedented global financial crisis. Hence, more prudent policies and further strengthening of policy frameworks, especially with respect to financial stability, seem warranted.

In Search of a Dramatic Equilibrium: Was the Armenian Dram Overvalued?
Description: This papers estimates the equilibrium exchange rate for Armenia using three different approaches: the purchasing power parity (PPP) approach, the behavioral equilibrium exchange rate (BEER) approach, and the external sustainability (ES) approach. All three approaches suggest that the dram was overvalued by about 20–30 percent prior to the devaluation of the dram in March 2009.

Current Account and Precautionary Savings for Exporters of Exhaustible Resources
Description: Exporters of exhaustible resources have historically exhibited higher income volatility than other economies, suggesting a heightened role for precautionary savings. This paper uses a parameterized small open economy model to quantify the role of precautionary savings in economies with exhaustible resources, when the only source of uncertainty is the price of the exhaustible resource. Results show that the precautionary motive can generate sizable external sector savings. When aggregated over the sample countries, precautionary savings in 2006 add up to 3.2 percent of GDP. The quantitative importance of the precautionary motive varies considerably across the sample countries and is driven primarily by the weight of exhaustible resource revenues in future income. The parameterized model fares well at capturing current account balances in both cross-section and time-series data.

Evaluating Historical CGER Assessments: How Well Have They Predicted Subsequent Exchange Rate Movements?
Description: The IMF's Consultative Group on Exchange Rate issues (CGER) has been conducting exchange rate assessments as part of the surveillance process since 1997. This paper evaluates CGER assessments from 1997 to 2006, by comparing these to subsequent movements in real effective exchange rates (REER). We find that CGER's estimated misalignments have predictive power over future REER movements, especially over longer horizons and after changes in fundamentals are accounted for. But while CGER misalignments frequently predict the direction of currency movements correctly, misalignments have tended to be persistent, resulting in systematic errors-overprediction for undervalued currencies and underprediction for overvalued currencies.

Are Capital Controls Effective in the 21st Century? the Recent Experience of Colombia
Description: This paper assesses the effects of capital controls imposed in Colombia in 2007 on capital flows and exchange rate dynamics. The results suggest that the controls were successful in reducing external borrowing, but had no statistically significant impact on the volume of non- FDI flows as a whole. We find no evidence that restrictions to capital mobility moderated the appreciation of Colombia's currency, or increased the degree of independence of monetary policy. We also find that controls have significantly increased the volatility of the exchange rate. Additional research is needed to assess the effects of capital controls on financial stability.

The Cost of Aggressive Sovereign Debt Policies: How Much is theprivate Sector Affected?
Description: This paper proposes a new empirical measure of cooperative versus conflictual crisis resolution following sovereign default and debt distress. The index of government coerciveness is presented as a proxy for excusable versus inexcusable default behaviour and used to evaluate the costs of default for the domestic private sector, in particular its access to international debt markets. Our findings indicate that unilateral, aggressive sovereign debt policies lead to a strong decline in corporate access to external finance (loans and bond issuance). We conclude that coercive government actions towards external creditors can have strong signalling effects with negative spillovers on domestic firms. "Good faith" debt renegotiations may be crucial to minimize the domestic costs of sovereign defaults.

The Value of Institutions for Financial Markets: Evidence From Emerging Markets
Description: This paper investigates the value of political institutions for financial markets, using panel data from emerging market countries. We test the hypothesis that changes in political institutions, such as improvements in democratic rights and increased government accountability, have a direct effect on sovereign interest rate spreads. We find that financial markets value institutions over and above the economic and fiscal outcomes these institutions shape. Democracy and accountability generally lower sovereign spreads, political risk tends to increase them, and financial markets tend to view election years negatively.

An Investigation of Some Macro-Financial Linkages of Securitization
Description: Policy-makers have attributed the scale of the credit crisis and its profound impact on money markets (as well as financial sector stability) to the fast rise of securitization and the way it has arguably complicated both the conduct of monetary policy and the effect of interest rate transmission to the real economy. In our study, we examine whether financial innovation, specifically through securitization, has altered the nature of some macro-financial linkages, often with considerable policy implications. We find that securitization activity in the United States (mature market) and South Africa (emerging market) has indeed dampened the interest rate elasticity of real output via the balance sheet channel (while decreasing the interest rate pass-through from policy rates to market rates). That being said, current reservations about securitization do not invalidate the fact that securitization activity helps cushion the immediate impact of interest rate shocks to loan origination, which might be particularly effective in EM countries where poorly developed capital markets provide few alternatives to bank lending.

Can Markets Compute Equilibria?
Description: Recent turmoil in financial and commodities markets has renewed questions regarding how well markets discover equilibrium prices, particularly when those markets are highly complex. A relatively new critique questions whether markets can realistically find equilibrium prices if computers cannot. For instance, in a simple exchange economy with Leontief preferences, the time required to compute equilibrium prices using the fastest known techniques is an exponential function of the number of goods. Furthermore, no efficient technique for this problem exists if a famous mathematical conjecture is correct. The conjecture states loosely that there are some problems for which finding an answer (i.e., an equilibrium price vector) is hard even though it is easy to check an answer (i.e., that a given price vector is an equilibrium). This paper provides a brief overview of computational complexity accessible to economists, and points out that the existence of computational problems with no best solution algorithm is relevant to this conjecture.

Regional Financial Spillovers Across Europe: A Global VAR Analysis
Description: The recent financial crisis raises important issues about the transmission of financial shocks across borders. In this paper, a global vector autoregressive (GVAR) model is constructed to assess the relevance of international spillovers following a historical slowdown in U.S. equity prices. The GVAR model contains 27 country-specific models, including the United States, 17 European advanced economies, and 9 European emerging economies. Each country model is linked to the others by a set of country-specific foreign variables, computed using bilateral bank lending exposures. Results reveal considerable comovements of equity prices across mature financial markets. However, the effects on credit growth are found to be country-specific. Evidence indicates that asset prices are the main channel through which-in the short run-financial shocks are transmitted internationally, while the contribution of other variables-like the cost and quantity of credit-becomes more important over longer horizons.
