The Economics of Political Transitions: Implications for the Arab Spring
Description: Over the past two years, ongoing political transitions in many Arab countries have led to social unrest and an economic downturn. This paper examines comparable historical episodes of political instability to derive implications for the near- and medium-term economic outlook in the Arab countries in transition. In general, past episodes of political instability were characterized by a sharp deterioration in macroeconomic outcomes and a sluggish recovery over the medium term. Recent economic developments in the Arab countries in transition seem to be unfolding along similar lines, although the weak external environment and large fiscal vulnerabilities could result in a prolonged slump.

The Challenge of Debt Reduction during Fiscal Consolidation
Description: Studies suggest that fiscal multipliers are currently high in many advanced economies. One important implication is that fiscal tightening could raise the debt ratio in the short term, as fiscal gains are partly wiped out by the decline in output. Although this effect is not long-lasting and debt eventually declines, it could be an issue if financial markets focus on the short-term behavior of the debt ratio, or if country authorities engage in repeated rounds of tightening in an effort to get the debt ratio to converge to the official target. We discuss whether these problems could be addressed by setting and monitoring debt targets in cyclically-adjusted terms.

The Impact of Uncertainty Shocks on the UK Economy
Description: This paper quantifies the economic impact of uncertainty shocks in the UK using data that span the recent Great Recession. We find that uncertainty shocks have a significant impact on economic activity in the UK, depressing industrial production and GDP. The peak impact is felt fairly quickly at around 6-12 months after the shock, and becomes statistically negligible after 18 months. Interestingly, the impact of uncertainty shocks on industrial production in the UK is strikingly similar to that of the US both in terms of the shape and magnitude of the response. However, unemployment in the UK is less affected by uncertainty shocks. Finally, we find that uncertainty shocks can account for about a quarter of the decline in industrial production during the Great Recession.

Rules, Discretion, and Macro-Prudential Policy
Description: The paper examines the implementation of macro-prudential policy. Given the coordination, flow of information, analysis, and communication required, macro-prudential frameworks will have weaknesses that make it hard to implement policy. And dealing with the political economy is also likely to be challenging. But limiting discretion through the formulation of macro-prudential rules is complicated by the difficulties in detecting and measuring systemic risk. The paper suggests that oversight is best served by having a strong baseline regulatory regime on which a time-varying macro-prudential policy can be added as conditions warrant and permit.

Rating Through-the-Cycle: What does the Concept Imply for Rating Stability and Accuracy?
Description: Credit rating agencies face a difficult trade-off between delivering both accurate and stable ratings. In particular, its users have consistently expressed a preference for rating stability, driven by the transactions costs induced by trading when ratings change frequently. Rating agencies generally assign ratings on a through-the-cycle basis whereas banks' internal valuations are often based on a point-in-time performance, that is they are related to the current value of the rated entity's or instrument's underlying assets. This paper compares the two approaches and assesses their impact on rating stability and accuracy. We find that while through-the-cycle ratings are initially more stable, they are prone to rating cliff effects and also suffer from inferior performance in predicting future defaults. This is because they are typically smooth and delay rating changes. Using a through-the-crisis methodology that uses a more stringent stress test goes halfway toward mitigating cliff effects, but is still prone to discretionary rating change delays.

Stock-Flow Adjustments, Government’s Integrated Balance Sheet and Fiscal Transparency
Description: This paper re-examines the stock-flow discrepancies of government debt and deficits and correlation with fiscal transparency. Applying the fully integrated relationship between financial stocks and flows allows for a more refined analysis of the deterministic components that make up the ‘stock-flow’ residual. Using partial measures of these stock-flow residuals, several empirical studies have found them to be significantly correlated with fiscaltransparency, inflation, fiscal rules, and banking crisis. Using fully integrated public finance data from the IMF Government Finance Statistics Yearbook for a sample of 22 countries, the findings in this paper suggest that stock-flow residuals have a significantly smaller magnitude than previously assumed and are, in fact, not correlated with fiscal transparency. A stronger determinant of fiscal transparency scores appears to be the actual reporting of fiscal data covering general government, especially a full financial balance sheet.

Export Performance in Europe: What Do We Know from Supply Links?
Description: One of the most important recent developments in international trade is the increasing interconnectedness of export production through a vertical trading chain network that streches across many countries, with each country specializing in particular stages of a good’s production. Using value added trade statistics, this paper tries to dissect and reshape understanding of European exports: where exports values are created, the role of vertical supply links in export growth, what is contributing to the growth in supply links, and how comparative advantages of countries are affected by supply links over time. Our analysis finds strong role of supply links in cross-country export performance in Europe, where these links between countries grew based on physical proximity, cost differential and similarity in export structure.

Forecasting and Monetary Policy Analysis in Low-Income Countries: Food and non-Food Inflation in Kenya
Description: We develop a semi-structural new-Keynesian open-economy model, with separate food and non-food inflation dynamics, for forecasting and monetary policy analysis in low-income countries and apply it to Kenya. We use the model to run several policy-relevant exercises. First, we filter international and Kenyan data (on output, inflation and its components, exchange rates and interest rates) to recover a model-based decomposition of most variables into trends (or potential values) and temporary movements (or gaps)—including for the international and domestic relative price of food. Second, we use the filtration exercise to recover the sequence of domestic and foreign macroeconomic shocks that account for business cycle dynamics in Kenya over the last few years, with a special emphasis on the various factors (international food prices, monetary policy) driving inflation. Third, we perform an out-of-sample forecast to identify where the economy—and therefore policy—was likely headed given the inflationary pressures at the end of our sample (2011Q2). We find that while imported food price shocks have been an important source of inflation, both in 2008 and more recently, accommodating monetary policy has also played a role, most notably through its effect on the nominal exchange rate. The model correctly predicted that a policy tightening was required, although the actual interest rate increase was larger. We discuss implications for the use of model-based policy analysis in low income countries.

Quarterly GDP Revisions in G-20 Countries: Evidence from the 2008 Financial Crisis
Description: This paper presents a statistical analysis of revisions in quarterly gross domestic product (GDP) of the Group of Twenty countries (G-20) since 2000. The main objective is to assess whether the reliability of early estimates of quarterly GDP has been weakened from the turmoil of the 2008 financial crisis. The results indicate that larger and more downward revisions were observed during the years 2008 and 2009 than in previous years.

External Linkages and Policy Constraints in Saudi Arabia
Description: The constraints that external linkages impose on domestic policy choices in Saudi Arabia have continuously evolved over the past four decades. This paper argues that two major ongoing developments in particular have affected and will continue to affect policy trade-offs. First, growing oil needs of emerging market economies (EMEs), and specifically those of developing Asia, have strengthened economic links between the Far East and Saudi Arabia. Second, financial sector development in Saudi Arabia has gradually strengthened the monetary transmission mechanism. The former implies the increased importance of developing Asia’s growth cycle for the Saudi economy, while the latter suggests greater influence of U.S. monetary policy on the non-oil economy through the peg to the U.S dollar. As a result, divergence between the growth cycles in developing Asia and the United States has the potential to increasingly generate tension between policy objectives in Saudi Arabia.
