The Transmission Mechanism in Armenia: New Evidence from a Regime Switching VAR Analysis
Description: The introduction of inflation targeting in 2006, together with important economic developments such as dedollarization, marked the beginning of a new macroeconomic framework in Armenia, which is likely to have changed the effectiveness of monetary policy. This paper is the first attempt to analyze whether the transmission mechanism in Armenia has been subject to a structural break by employing a Markov-Switching VAR framework. Results support the existence of such a structural break around the time inflation targeting was introduced and reduced levels of dollarization were observed. Results from introducing a threshold variable into this framework furthermore show that reduced levels of dollarization are an important determinant of the effectiveness of monetary policy.

Financial Innovation and Risk, the Role of Information
Description: Financial innovation has increased diversification opportunities and lowered investment costs, but has not reduced the relative cost of active (informed) investment strategies relative to passive (less informed) strategies. What are the consequences? I study an economy with linear production technologies, some more risky than others. Investors can use low quality public information or collect high quality, but costly, private information. Information helps avoiding excessively risky investments. Financial innovation lowers the incentives for private information collection and deteriorates public information: the economy invests more often in excessively risky technologies. This changes the business cycle properties and can reduce welfare by increasing the likelihood of "liquidation crises"

What Caused the Global Financial Crisis: Evidenceon the Drivers of Financial Imbalances 1999: 2007
Description: This paper investigates empirically the drivers of financial imbalances ahead of the global financial crisis. Three factors may have contributed to the build-up of financial imbalances: (i) rising global imbalances (capital flows), (ii) monetary policy that might have been too loose, (iii) inadequate supervision and regulation. Panel data regressions are performed for OECD countries from 1999 to 2007, so as to shed light on the relative importance of these factors, as well as the extent to which these factors might have interacted in fuelling the build-up. We find that the build-up of financial imbalances was driven by capital inflows and an associated compression of the spread between long and short rates. The effect of capital inflows on the build-up is amplified where the supervisory and regulatory environment was relatively weak. We find that, by contrast, differences in monetary policy cannot account for differences across countries in the build-up of financial imbalances ahead of the crisis.

Private Sector Consumption and Government Consumption and Debt in Advanced Economies: An Empirical Study
Description: This paper explores the hypothesis that the propensity to consume out of income varies in a non-linear fashion with fiscal variables, and in particular with government debt per capita. Using data from eighteen OECD countries the paper examines whether there is any empirical evidence to support the hypothesis that households move from non-Ricardian to Ricardian behavior as government debt reaches high levels and as uncertainty about future taxes increases. Our results provide support for this hypothesis, and also suggest that private and government consumption are substitutes in the household utility function.

A New Index of Currency Mismatch and Systemic Risk
Description: This paper constructs a new measure of currency mismatch in the banking sector that controls for bank lending to unhedged borrowers. This measure explicitly takes into account the indirect exchange rate risk that banks undertake when they lend to borrowers that will not be able to repay in the event of a sharp depreciation. Such systemic risk taking is not captured by indicators that are based only on banks’ balance sheet data. The new measure is constructed for 10 emerging European economies and for a broader sample that includes 19 additional emerging economies, for the period 1998 - 2008. Comparisons with previous currency mismatch measures that do not adjust for unhedged foreign currency borrowing illustrate the advantages of the new approach. In particular, the new measure flagged the indirect currency mismatch vulnerabilities that were building up in a number of emerging economies before the recent global crisis. Measuring currency mismatch more accurately can help country authorities in their efforts to address vulnerabilities at the right time, avoiding hurting growth prospects.

Unemployment and Productivity in the Long Run: the Role of Macroeconomic Volatility
Description: We propose a theory of low-frequency movements in unemployment based on asymmetric real wage rigidities. The theory generates two main predictions: long-run unemployment increases with (i) a fall in long-run productivity growth and (ii) a rise in the variance of productivity growth. Evidence based on U.S. time series and on an international panel strongly supports these predictions. The empirical specifications featuring the variance of productivity growth can account for two U.S. episodes which a linear model based only on long-run productivity growth cannot fully explain. These are the decline in long-run unemployment over the 1980s and its rise during the late 2000s.

On the Estimation of Term Structure Models and An Application to the United States
Description: This paper discusses the estimation of models of the term structure of interest rates. After reviewing the term structure models, specifically the Nelson-Siegel Model and Affine Term- Structure Model, this paper estimates the terms structure of Treasury bond yields for the United States with pre-crisis data. This paper uses a software developed by Fund staff for this purpose. This software makes it possible to estimate the term structure using at least nine models, while opening up the possibility of generating simulated paths of the term structure.

Determinants of the Foreign Exchange Risk Premium in Gulf Cooperation Council Countries
Description: This paper analyzes macroeconomic determinants of the foreign exchange risk premium in two Gulf Cooperation Council (GCC) countries that peg their currencies to the U.S. dollar: Saudi Arabia and the United Arab Emirates. The analysis is based on the stochastic discount factor methodology, which imposes a no arbitrage condition on the relationship between the foreign exchange risk premium and its macroeconomic determinants. Estimation results suggest that U.S. inflation and consumption growth are important factors driving the risk premium, which is in line with the standard C-CAPM model. In addition, growth in international oil prices influences the risk premium, reflecting the important role played by the hydrocarbon sector in GCC economies. The methodology employed in this paper can be used for forecasting the risk premium on a monthly basis, which has important practical implications for policymakers interested in the timely monitoring of risks in the GCC.

After the Crisis: Assessing the Damage in Italy
Description: Italy’s deep-rooted structural problems resulted in an unsatisfactory productivity performance and a dismal growth over the last 15 years. The global financial crisis has exacerbated these long-standing weaknesses, taking a heavy toll on Italy’s economy. With output back to its end-2001 level, Italy’s output losses associated with the crisis have been, thus far, about 132 billion of 2000 euro (around 10 percent of precrisis 1998 - 2004 real GDP). About three quarters of these losses are estimated to be due to a shortfall in potential output. Potential output is not expected to rebound to its precrisis trend over the medium term, even though growth is projected to do so within the next two years. In the short-run, the decline in output is mainly accounted for by a collapse in productivity; in the medium term, employment and capital are also likely to be affected, with implications for the longer-term growth and fiscal outlook.

Monetary and Fiscal Policy Interactions in the Post-war U.S
Description: A New Keynesian model allowing for an active monetary and passive fiscal policy (AMPF) regime and a passive monetary and active fiscal policy (PMAF) regime is fit to various U.S. samples from 1955 to 2007. Data in the pre-Volcker periods strongly prefer an AMPF regime, but the estimation is not very informative about whether the inflation coefficient in the interest rate rule exceeds one in pre-Volcker samples. Also, whether a government spending increase yields positive consumption in a PMAF regime depends on price stickiness. An income tax cut can yield a negative labor response if monetary policy aggressively stabilizes output.
