Is the Growth Momentum in Latin America Sustainable?
Description: A favorable external environment coupled with prudent policies fostered output growth in most of Latin America during the last decade. But, what were the drivers of this strong growth performance from the supply side and will this momentum be sustainable in the years ahead? We address these questions by identifying the proximate causes of the recent high GDP growth and estimating potential growth rates for the period ahead for a large group of Latin American countries based on standard (Solow-style) growth accounting methodologies. We find that factor accumulation (especially labor), rather than growth in total factor productivity (TFP), remains the main driver of GDP growth. Moving forward, given the expected moderation of capital accumulation and some natural constraints on labor, the strong growth momentum is unlikely to be sustainable unless TFP performance improves significantly.

Capital Account Policies in Chile Macro-financial considerations along the path to liberalization
Description: This paper recounts Chile’s experience with capital account policies since the 1990s. We present how two external shocks were confronted under very different macroeconomic and capital account frameworks. We show that during the 1997-98 Asian-LTCM-Russia crisis, a closed capital account and relatively rigid exchange rate severely constrained the monetary policy response to the shock, aggravating the fall in domestic demand. During the 2008-09 crisis, a full-fledged inflation targeting framework allowed the authorities to implement a significant countercyclical response. We argue that domestic stability considerations lay behind the policy regime switch toward capital account liberalization from 1999 onwards.

Credit Growth in Latin America: Financial Development or Credit Boom?
Description: Banking credit to the private sector in Latin America has on average increased by 7 percent of GDP from primo 2004 to ultimo 2011, with real credit in some countries growing by up to 20 percent per year. This paper documents and analyzes the patterns of credit growth in 18 countries in Latin America and uses econometric methods to determine whether it is indicative of financial deepening or poses risks of credit booms. The strongest credit growth occurred for consumption and mortgages within the household sector and for construction within the corporate sector. At the same time credit has de-dollarized in most countries and there are some signs of maturity lengthening. To assess whether the recent credit growth is excessive two different methods are applied. First, by application of HP-filters the paper finds that credit-to-GDP levels in a number of countries are above their long-term trend. Second, using a panel co-integration approach on 107 high and mid-income countries the paper estimates a model for the credit-to-GDP levels. Comparing the actual levels of credit with the ones predicted by the model we find that some countries in Latin America show significant and positive deviations. These results indicate the existence of a certain level of risk in the recent credit developments.

What Is in Your Output Gap? Unified Framework & Decomposition into Observables
Description: This paper discusses several popular methods to estimate the ‘output gap’. It provides a unified, natural concept for the analysis, and demonstrates how to decompose the output gap into contributions of observed data on output, inflation, unemployment, and other variables. A simple bar-chart of contributing factors, in the case of multi-variable methods, sharpens the intuition behind the estimates and ultimately shows ‘what is in your output gap.’ The paper demonstrates how to interpret effects of data revisions and new data releases for output gap estimates (news effects) and how to obtain more insight into real-time properties of estimators.

The Pacific Speed of Growth: How Fast Can It Be and What Determines It?
Description: This study aims to test within a relatively homogeneous group of small states what differentiates the growth performance of Pacific island countries (PICs) from their peers. We find that PICs are disadvantaged by distance and hampered by lower investment and exports compared with other small island states, but greater political stability, catch-up effects from lower initial incomes, and slower population growth have helped offset some of these disadvantages. On balance, policy-related factors, together with geography-related disadvantages, have led to growth rates in PICs that are much lower than in other small states. We also examine how real exchange rate appreciation, unfavorable developments in the external trade environment, and rising international transport costs may have contributed to PICs’ slower growth over the past decade.

Four Decades of Terms-of-Trade Booms: Saving-Investment Patterns and a New Metric of Income Windfall
Description: We study the history of terms-of-trade booms (during 1970–2012), with a focus on Latin America, through the prisms of a simple metric that quantifies the associated income windfall. We also document saving patterns during these episodes and propose a measure of how much of the income windfall was saved. We find that Latin America‘s terms-of-trade shocks of the last decade have not differed much in magnitude from those observed during the 1970s, but that the associated windfall have been substantially larger. While aggregate saving increased more than in past episodes, the share of the windfall saved (the marginal saving rate) seems to be lower, suggesting that greater aggregate saving reflects mainly the sheer size of the windfall rather than a greater 'effort' to save it. Finally, we find evidence that, while savings during the boom help to increase post-boom income, the composition of such savings matters. Specifically, in past episodes, savings allocated to foreign asset accumulation appear to have contributed more to post-boom income than those devoted to domestic investment.

Balance Sheet Strength and Bank Lending During the Global Financial Crisis
Description: We examine the role of bank balance sheet strength in the transmission of financial sector shocks to the real economy. Using data from the syndicated loan market, we exploit variation in banks’ reliance on wholesale funding and their structural liquidity positions in 2007Q2 to estimate the impact of exposure to market freezes during 2007–08 on the supply of bank credit. We find that banks with strong balance sheets were better able to maintain lending during the crisis. In particular, banks that were ex-ante more dependent on market funding and had lower structural liquidity reduced the supply of credit more than other banks. However, higher and better-quality capital mitigated this effect. Our results suggest that strong bank balance sheets are key for the recovery of credit following crises, and provide support for regulatory proposals under the Basel III framework.

The Impact of Foreign Bank Deleveraging on Korea
Description: Korea was hit hard by the 2008 global financial crisis, with the foreign bank deleveraging channel coming prominently into play. The global financial crisis demonstrated that a sharp deleveraging can be transmitted to emerging markets through the bank lending channel to a slowdown in credit growth. The analysis finds that a sharp decline in external funding led to relatively modest decline in domestic credit by Korean banks, due to concerted policy efforts by the government in 2008. Impulse responses from a Dynamic Stochastic General Equilibrium (DSGE) model calibrated to Korea shows that it appears better prepared to handle such shocks relative to 2008. Indeed, Korea is much more resilient to such shocks due to the efforts by the authorities, which has led to the strengthening of external buffers, such as higher foreign exchange reserves and bilateral and multilateral currency swap arrangements.

Measuring Competitiveness: Trade in Goods or Tasks?
Description: With global supply chains, any value added or production task can be traded as part of goods. This means that competitiveness can be measured either in terms of “tasks” (Bems and Johnson, 2012), or goods, but with goods prices reflecting the cost of tasks embedded in those goods. We show that when measuring competitiveness in goods, the formula used in computing the real effective exchange rates at the IMF (Bayoumi, Lee, and Jayanthi, 2005) needs to be expressed in terms of the price of value added and needs an additional term, which captures a gain or loss in competitiveness of goods due to outsourcing.

Understanding DSGE Filters in Forecasting and Policy Analysis
Description: This paper introduces methods that allow analysts to (i) decompose the estimates of unobserved quantities into observed data, (ii) to better understand revision properties of the model, and (iii) to impose subjective prior constraints on path estimates of unobserved shocks in structural economic models. For instance, a decomposition of the flexible-price output gap, or a technology shock, into contributions of output, inflation, interest rates, and other observed variables' contribution is feasible. The intuitive nature and analytical clarity of the suggested procedures are appealing for policy-related and forecasting models.
