Real-time Forecasts of Economic Activity for Latin American Economies
Description: Macroeconomic policy decisions in real-time are based the assessment of current and future economic conditions. These assessments are made difficult by the presence of incomplete and noisy data. The problem is more acute for emerging market economies, where most economic data are released infrequently with a (sometimes substantial) lag. This paper evaluates "nowcasts" and forecasts of real GDP growth using five alternative models for ten Latin American countries. The results indicate that the flow of monthly data helps to improve forecast accuracy, and the dynamic factor model consistently produces more accurate nowcasts and forecasts relative to other model specifications, across most of the countries we consider.

Lessons for Monetary Policy: What Should the Consensus Be?
Description: This paper outlines important lessons for monetary policy. In particular, the role of inflation targeting, which was much acclaimed prior to the financial crisis and since then has not lost much of its endorsement, is critically reviewed. Ignoring the relation between monetary policy and asset prices, as is the case in this monetary policy approach, can lead to financial instability. In contrast, giving, inter alia, monetary factors a role in central banks’ policy decisions, as is done in the ECB’s encompassing approach, helps prevent these potentially harmful side effects and thus allows for fostering financial stability. Finally, this paper makes a case against increasing the central banks’ inflation target.

International Mutual Funds, Capital Flow Volatility, and Contagion – A Survey
Description: Gaining a better understanding of the behavior of international investors is key for informing the debate about the optimal response to capital flows and about reforms to the international financial architecture. In this context, recent research on the behavior of international mutual funds at the micro level has expanded our knowledge about the drivers of portfolio flows and the mechanisms behind the transmission of financial shocks across countries. This paper provides a brief survey of this literature, with a focus on the empirical evidence for emerging markets. Overall, the behavior of international mutual funds is complex and overly simplistic characterizations are misleading. However, there is broad-based evidence for momentum trading among funds. Moreover, funds tend to avoid opaque markets and assets, and this behavior becomes more pronounced during volatile times. Portfolio rebalancing mechanisms are clearly important in explaining contagion patterns, even in the absence of common macroeconomic fundamentals. From a surveillance point of view, this implies that monitoring the exposures of large investors at a micro level is crucial to assess vulnerabilities.

How to Deal with Real Estate Booms: Lessons from Country Experiences
Description: The financial crisis showed, once again, that neglecting real estate booms can have disastrous consequences. In this paper, we spell out the circumstances under which a more active policy agenda on this front would be justified. Then, we offer tentative insights on the pros and cons as well as implementation challenges of various policy tools that can be used to contain the damage to the financial system and the economy from real estate boom-bust episodes.

How Do Business and Financial Cycles Interact?
Description: This paper analyzes the interactions between business and financial cycles using an extensive database of over 200 business and 700 financial cycles in 44 countries for the period 1960:1-2007:4. Our results suggest that there are strong linkages between different phases of business and financial cycles. In particular, recessions associated with financial disruption episodes, notably house price busts, tend to be longer and deeper than other recessions. Conversely, recoveries associated with rapid growth in credit and house prices tend to be stronger. These findings emphasize the importance of developments in credit and housing markets for the real economy.

Identifying the Linkages between Major Mining Commodity Prices and China’s Economic Growth—Implications for Latin America
Description: Major mining commodity prices are inherently volatile and cyclical. High levels of investment in China have been a key driver in the strong world demand for minerals and metals over the past decade. The urbanization and industrialization of China has been an important factor behind the increase in domestic demand and high investment growth, while its export sector is also an important source of growth and plays a critical role as a catalyst. Activity in infrastructure, construction, real estate, and automobile manufacturing all contribute to the strong demand for minerals. Over the next five years, the Chinese demand is expected to remain strong, supported by investment and gradually rising consumption rates. However, in the second part of this decade economic growth in China could slow down. For Latin American countries, export receipts should remain strong over the next five years and beyond, given the continued strong demand from China.

Fat-Tails and their (Un)Happy Endings: Correlation Bias and its Implications for Systemic Risk and Prudential Regulation
Description: The correlation bias refers to the fact that claim subordination in the capital structure of the firm influences claim holders’ preferred degree of asset correlation in portfolios held by the firm. Using the copula capital structure model, it is shown that the correlation bias shifts shareholder preferences towards highly correlated assets, making financial institutions more prone to fail and increasing systemic risk given interconnectedness in the financial system. The implications for systemic risk and prudential regulation are assessed under the prism of Basel III, and potential solutions involving changes to the prudential framework and corporate governance are suggested.

Feeling The Elephant’s Weight: The Impact of Côte d’Ivoire’s Crisis on WAEMU Trade
Description: This paper analyzes the impact of political instability in Côte d’Ivoire on WAEMU trade over 1990-2007, applying panel econometric techniques to a gravity model of trade within WAEMU and between WAEMU and the rest of the world. The paper finds that intra-regional trade represents a small share of total WAEMU trade and that Côte d’Ivoire accounts for around half of that total, highlighting the importance of this country for the region. The political instability in Côte d’Ivoire has led to an increase in transaction costs, making it relatively more costly for member countries to trade with each other than with the rest of world. Instability has also resulted in a diversion of trade away from Côte d’Ivoire in favor of other countries equipped with ports and in a reduction of WAEMU overall potential trade. For Côte d’Ivoire alone, lost trade is estimated at around 40 percent of its potential trade with the WAEMU in the absence of instability. With a normalization in Côte d’Ivoire, enhanced security and further integration would be essential to achieve higher levels of trade and growth in the WAEMU region.

Mongolia: Measuring the Output Gap
Description: This paper compares the output gap estimates for Mongolia based on a number of different methods. Special attention is paid to the substantial role of mining in the Mongolian economy. We find that a Blanchard and Quah-type joint model of output and inflation provides a more robust estimate of the output gap for Mongolia than the traditional statistical decompositions.

ICT, Financial Inclusion, and Growth: Evidence from African Countries
Description: This paper studies the impact of information and communication technologies (ICT), especially mobile phone rollout, on economic growth in a sample of African countries from 1988 to 2007. Further, we investigate whether financial inclusion is one of the channels through which mobile phone development influences economic growth. In estimating the impact of ICT on economic growth, we use a wide range of ICT indicators, including mobile and fixed telephone penetration rates and the cost of local calls. We address any endogeneity issues by using the System Generalized Method of Moment (GMM) estimator. Financial inclusion is captured by variables measuring access to financial services, such as the number of deposits or loans per head, compiled by Beck, Demirguc-Kunt, and Martinez Peria (2007) and the Consultative Group to Assist the Poor (CGAP, 2009). The results confirm that ICT, including mobile phone development, contribute significantly to economic growth in African countries. Part of the positive effect of mobile phone penetration on growth comes from greater financial inclusion. At the same time, the development of mobile phones consolidates the impact of financial inclusion on economic growth, especially in countries where mobile financial services take hold.
