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.

Productivity or Employment: Is It a Choice?
Description: Traditionally, shocks to total factor productivity (TFP) are considered exogenous and the employment response depends on their effect on aggregate demand. We raise the possibility that in response to labor supply shocks firms adjust efficiency, rendering TFP endogenous to firms’ production decisions. We present robust cross-country evidence of a strong negative correlation between growth in TFP and labor inputs over the medium to long run. In addition, when using instruments to capture changes in hours worked that are independent of TFP shocks, we find that cross-country increases in labor input cause reductions in TFP growth. These results have important policy implications, including that low productivity growth in some countries may partly be a side effect of strong labor market performance. By the same token, countries facing a declining workforce, say, because of aging, may see accelerating TFP as firms find better ways of employing workers.

Monetary Policy in Emerging Markets: Taming the Cycle
Description: In contrast to advanced markets (AMs), procyclical monetary policy has been a problem for emerging markets (EMs), with macroeconomic policies amplifying economic upswings and deepening downturns. The stark difference in policy has not been subject to extensive study and this paper attempts to address the gap. Key findings, using a large sample of EMs over the past 50 years, are: (i) EMs have adopted increasingly countercyclical monetary policy over time, although large differences remain among EMs and policies became more procyclical during the recent crisis. (ii) Inflation targeting and better institutions have been key factors behind the move to countercyclicality. (iii) Only deep financial markets allow EMs with flexible exchange rate regimes turn countercyclical. (iv) More countercyclical policy is associated with far less volatile output. The economically meaningful impact of IT on monetary policy countercyclicality and output variability is another reason in its favor, over and above better inflation outcomes.

Another Look at Governments’ Balance Sheets: The Role of Nonfinancial Assets
Description: When discussing debt reduction strategies, little attention has been given to the role of governments’ nonfinancial assets. This is in part because data are scarce. Drawing on various data sources, this paper looks at the size, composition, and management of state-owned nonfinancial assets across 32 economies, with particular focus on the advanced G-20 economies. We find that reported nonfinancial assets comprise mostly structures (such as roads and buildings) and,when valued, land. These assets have increased over time, mostly due to higher property and commodity prices, and are, in large part, owned by subnational governments. Many countries have launched reforms with a view to streamlining public administrations, but receipts and savings have been rather small so far. Governments tend to consider relatively small sets of assets to be disposable, though preferences could change in the future. A potential source for future revenues could be greater reliance on user charges, such as road tolls. In most cases, a first step for more effective asset management has to be the expansion and improvement of data compilation.

International Evidence on Government Support and Risk Taking in the Banking Sector
Description: Government support to banks through the provision of explicit or implicit guarantees affects the willingness of banks to take on risk by reducing market discipline or by increasing charter value. We use an international sample of bank data and government support to banks for the periods 2003-2004 and 2009-2010. We find that more government support is associated with more risk taking by banks, especially during the financial crisis (2009-10). We also find that restricting banks' range of activities ameliorates the moral hazard problem. We conclude that strengthening market discipline in the banking sector is needed to address this moral hazard problem.

The Impact of Debt Sustainability and the Level of Debt on Emerging Markets Spreads
Description: How do financial markets respond to concerns over debt sustainability and the level of public debt in emerging markets? We introduce a measure of debt sustainability – the difference between the debt stabilizing primary balance and the primary balance–in an otherwise standard spread regression model applied to a panel of 26 emerging market economies. We find that debt sustainability is an important determinant of spreads. In addition, using a panel smooth transition regression model, we find that the sensitivity of spreads to debt sustainability doubles as public debt increases above 45 percent of GDP. These results suggest that market interest rates react more to debt sustainability concerns in a country with a high level of debt compared to a country with a low level of debt.

Searching for the Finance-Growth Nexus in Libya
Description: This paper investigates the causal relationship between financial development and economic growth in Libya during the period 1970–2010. The empirical results vary with estimation methodology and model specification, but indicate the lack of long-run relationship between financial intermediation and nonhydrocarbon output growth. The OLS estimation shows that financial development has a statistically significant negative effect on real nonhydrocarbon GDP per capita growth. However, the VAR-based estimations present statistically insignificant results, albeit still attaching a negative coefficient to financial intermediation. It appears that nonhydrocarbon economic activity depends largely on government spending, which is in turn determined by the country’s hydrocarbon earnings.

The Dynamic Effect of Social and Political Instability on Output: The Role of Reforms
Description: The aim of this paper is to analyze the dynamic effect of social and political instability on output. Using a panel of up to 183 countries from 1980 to 2010, the results of the paper suggest that social conflicts have a significant and negative impact on output in the short-term with the magnitude of the effect being a function of the intensity of political instability. The results also show that the recovery of output over the medium-term depends on the ability of the country to implement, in the aftermath of a social instability episode, reforms aimed at improving the level of governance. The results are robust to different checks and estimation strategies.

The Investment Technology of Foreign and Domestic Institutional Investors in an Emerging Market
Description: The literature on the investment technology of foreign versus domestic investors has inconclusive results. This paper revisits the question, with a focus on decomposing portfolio performance into asset allocation and security selection. We document signicant differences in exposure to systematic asset pricing factors between foreign and domestic investors. A quasi-experimental strategy is introduced, for comparing security selection after controlling for diferences in asset allocation. Our results show that foreign investors in India do remarkably poorly at security selection.

Fiscal Sustainability: A 21st Century Guide for the Perplexed
Description: This paper critically reviews recent work regarding the sustainability of public debt. It argues that Debt Sustainability Analyses (DSAs) should be more than mere mechanical simulation exercises. Instead, a DSA should be linked to some objective regarding the distribution of fiscal burdens and distortions over time (in the tradition of Barro’s 1979 tax smoothing objective). The paper discusses objective functions that yield simple and transparent fiscal policy rules.
