Can Policies Affect Employment Intensity of Growth? A Cross-Country Analysis
Description: The aim of this paper is to provide new estimates of employment-output elasticities and assess the effect of structural and macroeocnomic policies on the employment-intensity of growth. Using an unbalanced panel of 167 countries over the period 1991 - 2009, the results suggest that structural policies aimed at increasing labor and product market flexibility and reducing government size have a significant and positive impact on employment elasticities. In addition, the results also suggest that in order to maximize the positive impact on the responsiveness of employment to economic activity, structural policies have to be complemented with macroeconomic policies aimed at increasing macroeconomic stability.

Emerging Market Sovereign Bond Spreads: Estimation and Back-testing
Description: We estimate sovereign bond spreads of 28 emerging economies over the period January 1998-December 2011 and test the ability of the model in generating accurate in-sample predictions for emerging economies bond spreads. The impact and significance of country-specific and global explanatory variables on bond spreads varies across regions, as well as economic periods. During crisis times, good macroeconomic fundamentals are helpful in containing bond spreads, but less than in non-crisis times, possibly reflecting the impact of extra-economic forces on bond spreads when a financial crisis occurs. For some emerging economies, in-sample predictions of the monthly changes in bond spreads obtained with rolling regression routines are significantly more accurate than forecasts obtained with a random walk. Rolling regression-based bond spread predictions appear to convey more information than those obtained with a linear prediction method. By contrast, bond spreads forecasts obtained with a linear prediction method are less accurate than those obtained with random guessing.

The Cyclicality of Sales, Regular and Effective Prices: Business Cycle and Policy Implications
Description: We study the cyclical properties of sales, regular price changes and average prices paid by consumers ("effective" prices) in a dataset containing prices and quantities sold for numerous retailers across a variety of U.S. metropolitan areas. Both the frequency and size of sales fall when local unemployment rates rise and yet the inflation rate for effective prices paid by consumers declines significantly with higher unemployment. This discrepancy can be reconciled by consumers reallocating their expenditures across retailers, a feature of the data which we document and quantify. We propose a simple model with household shopping effort and store-switching consistent with these stylized facts and document its implications for business cycles and policymakers.

Donor Competition for Aid Impact, and Aid Fragmentation
Description: This paper shows that donors that maximize relative aid impact spread their budgets across many recipient countries in a unique Nash equilibrium, explaining aid fragmentation. This equilibrium may be inefficient even without fixed costs, and the inefficiency increases in the equality of donors budgets. The paper presents empirical evidence consistent with theoretical results. These imply that, short of ending donors maximization of relative aid impact, agreements to better coordinate aid allocations are not implementable. Moreover, since policies to increase donor competition in terms of aid effectiveness risk reinforcing relativeness, they may well backfire, as any such reinforcement increases aid fragmentation.

Resource Windfalls, Optimal Public Investment and Redistribution: The Role of Total Factor Productivity and Administrative Capacity
Description: This paper studies the optimal public investment decisions in countries experiencing a resource windfall. To do so, we use an augmented version of the Permanent Income framework with public investment faced with adjustment costs capturing the associated administrative capacity as well as government direct transfers. A key assumption is that those adjustment costs rise with the size of the resource windfall. The main results from the analytical model are threefold. First, a larger resource windfall commands a lower level of public capital but a higher level of redistribution through transfers. Second, weaker administrative capacity lowers the increase in optimal public capital following a resource windfall. Third, higher total factor productivity in the non-resource sector reduces the degree of des-investment in public capital commanded by weaker administrative capacity. We further extend our basic model to allow for "investing in investing" - that is public investment in administrative capacity - by endogenizing the adjustment cost in public investment. Results from the numerical simulations suggest, among other things, that a higher initial stock of public administrative "know how" leads to a higher level of optimal public investment following a resource windfall. Implications for policy are discussed.

Innocent Bystanders? Monetary Policy and Inequality in the U.S.
Description: We study the effects and historical contribution of monetary policy shocks to consumption and income inequality in the United States since 1980. Contractionary monetary policy actions systematically increase inequality in labor earnings, total income, consumption and total expenditures. Furthermore, monetary shocks can account for a significant component of the historical cyclical variation in income and consumption inequality. Using detailed micro-level data on income and consumption, we document the different channels via which monetary policy shocks affect inequality, as well as how these channels depend on the nature of the change in monetary policy.

Latin America: Vulnerabilities Under Construction?
Description: This paper documents developments in mortgage credit and the housing sector in Latin America over the past decade, and compares them with those of other emerging economies. In particular, it examines the real estate and mortgage markets to assess whether (i) growth in mortgage credit is excessive compared to long-term trends; (ii) trends in house prices reflect changes in economic fundamentals; and (iii) the extent to which household and banking sector vulnerabilities could lead to potential fragilities. Although data limitations hamper a rigorous analysis of trends, our analysis suggests that while there are no imminent misalignments in the real estate and mortgage sectors, they could emerge if current trends persist. Strengthening supervision and addressing data gaps is thus critical to ensure adequate monitoring of risks and vulnerabilities in these sectors.

Lost in Transmission? The Effectiveness of Monetary Policy Transmission Channels in the GCC Countries
Description: This paper empirically investigates the effectiveness of monetary policy transmission in the Gulf Cooperation Council (GCC) countries using a structural vector autoregressive model. The results indicate that the interest rate and bank lending channels are relatively effective in influencing non-hydrocarbon output and consumer prices, while the exchange rate channel does not appear to play an important role as a monetary transmission mechanism because of the pegged exchange rate regimes. The empirical analysis suggests that policy measures and structural reforms - strengthening financial intermediation and facilitating the development of liquid domestic capital markets - would advance the effectiveness of monetary transmission mechanisms in the GCC countries.

Successful Austerity in the United States, Europe and Japan
Description: The output effects of 2009 fiscal expansions have been hotly debated. But the discussion of fiscal multipliers is even more relevant now that several European countries have had to quickly retract their stimulus measures in an effort to regain market confidence. Using regime-switching VARs we estimate the impact of fiscal adjustment on the United States, Europe and Japan allowing for fiscal multipliers to vary across recessions and booms. We also estimate ex ante probabilities of recessions derived in association with different-sized and different types of consolidation shocks (expenditure- versus tax-based). We use these estimates to understand how consolidations should be designed to be most effective in terms of permanently and rapidly reducing a country’s debt-to-GDP ratio. The main finding is that smooth and gradual consolidations are to be preferred to frontloaded or aggressive consolidations, especially for economies in recession facing high risk premia on public debt, because sheltering growth is key to the success of fiscal consolidation in these cases.

Japan out of the Lost Decade: Divine Wind or Firms’ Effort?
Description: A surge of exports in the 2000s helped Japan exit the severe decade-long stagnation known as the lost decade. Using panel data of Japanese exporting firms, we examine the sources of the export surge during this period. One view argues that the so-called "divine wind" or exogenous external demand boosted Japanese exports. The other view emphasizes the role of supply factors such as productivity gains, materialized after long-fought restructuring efforts during the lost decade. Estimating the firm-level export function allows us to assess the relative importance of these demand and supply factors. Evidence shows that firms' efforts were more important than the divine wind.
