The Macroeconomic Effects of Natural Resource Extraction: Applications to Papua New Guinea
Description: To investigate the effects on Papua New Guinea’s economy of substantial liquified natural gas revenues arriving in 2015, we employ a model to examine the macroeconomic effects of a scalingup of natural resource windfall revenues and the implications for a variety of policy responses. The model is a multi-sector dynamic stochastic general equilibrium (DSGE) model, and features components that allow for a detailed study of the effects of both fiscal and monetary policy in response to a positive shock to the mineral resource value of a country. The model contains tradable, non-tradable, and mining sectors, as well as an independent central bank and fiscal authority. We calibrate the model to the current economy of Papua New Guinea and run a suite of policy simulations. We find that macroeconomic effects from a resource boom typically associated with Dutch Disease effects such as a real appreciation and a fall in tradable sector production stem largely from the non-tradable component of government spending. The central bank can offset the real appreciation, but not without crowding out the private sector. A sovereign wealth fund (SWF), combined with a smooth capital spending path, entails the best means of dealing with macroeconomic volatility and maintaining a stable fiscal regime.

Measuring the Informal Economy in the Caucasus and Central Asia
Description: This study estimates the size of the informal economy, and the relative contribution of each underlying factor, for the Caucasus and Central Asia countries in 2008. Using a Multiple Indicator-Multiple Cause model, we find that a burdensome tax system, rigid labor market, low institutional quality, and excessive regulation in financial and products markets are determinant factors in explaining the size of the informal economy, which ranges from 26 percent of GDP in Kyrgyz Republic to around 35 percent of GDP in Armenia. Furthermore, the results show that higher levels of informality increase the levels of self employment and the percentage of currency held outside the banking system.

The Economic Effects of Fiscal Consolidation with Debt Feedback
Description: The past several years of recession and slow recovery have raised much interest on the effect of fiscal stimulus on economic activity, even as high public debts in many countries would call for fiscal consolidation. To evaluate the delicate balance between stimulus and consolidation requires measuring the size of fiscal multipliers, which often depends on having quarterly data so that exogenous fiscal policy shocks can be identified. We estimate fiscal multipliers using a novel methodology for identifying fiscal shocks within a structural vector autoregressive approach using annual data while controling for debt feedback effects. The estimation focuses on regions with scarce quarterly data (mostly low-income countries), and uses results for advanced economies, emerging market countries, and other broad groupings for which alternative estimates are available to validate the methodology. Differently from advanced and emerging market economies, fiscal consolidation in low-income countries has only a small temporary negative effect on growth while raising medium-term output. Shifting the composition of public spending toward capital expenditure further supports long-run growth.

Inclusive Growth: Measurement and Determinants
Description: We estimate a unified measure of inclusive growth for emerging markets by integrating their economic growth performance and income distribution outcomes, using data over three decades. Country distributions are calibrated by combining PPP GDP per capita and income distribution from survey data. We apply the microeconomic concept of a social mobility function at the macroeconomic level to measure inclusive growth that is closer to the absolute definition of pro-poor growth. This dynamic measure permits us to focus on inequality as well as distinguish between countries where per capita income growth was the same for the top and the bottom of the income pyramid, by accounting for the pace of growth. Our results indicate that macroeconomic stability, human capital, and structural changes are foundations for achieving inclusive growth. The role of globalization could also be positive with foreign direct investment and trade openess fostering greater inclusiveness, while financial deepening and technological change have no discernible effect.

Comparing Parametric and Non-parametric Early Warning Systems for Currency Crises in Emerging Market Economies
Description: The purpose of this paper is to compare in-sample and out-of-sample performances of three parametric and non-parametric early warning systems (EWS) for currency crises in emerging market economies (EMs). The parametric EWS achieves superior out-of-sample results compared to the non-parametric EWS, as the total misclassification error of the former is lower than that of the latter. In addition, we find that the performances of the parametric and non-parametric EWS do not improve if the policymaker becomes more prudent. From a policy perspective, the policymaker faces the standard trade-off when using EWS. Greater prudence allows the policymaker to correctly call more crisis episodes, but this comes at the cost of issuing more false alarms. The benefit of correctly calling more currency crises needs to be traded off against the cost of issuing more false alarms and of implementing corrective macroeconomic policies prematurely.

Afghanistan: Balancing Social and Security Spending in the Context of Shrinking Resource Envelope
Description: For Afghanistan, the dual prospect of declining donor support and high ongoing security spending over the medium term keeps the government budget tight. This paper uses a general equilibrium model to capture the security-development tradeoff facing the government in its effort to rehabilitate macroeconomic stability and welfare. In particular, it considers strategic policy options for counteracting and minimizing the negative macroeconomic impact of possible aid and revenue shortfalls. We find that the mobilization of domestic revenues through changes in tax policy is the preferred policy response for Afghan central government. Such a response helps to place its finances on a sustainable path and preserve most of the growth potential. Cutting expenditures balances public finances, but causes the economy to permanently shrink. Debt financing helps to preserve much of the economy size but can jeopardize the sustainability of public finances.

The Growth Comeback in Developing Economies: A New Hope or Back to the Future?
Description: Growth takeoffs in developing economies have rebounded in the past two decades. Although recent takeoffs have lasted longer than takeoffs before the 1990s, a key question is whether they could unravel like some did in the past. This paper finds that recent takeoffs are associated with stronger economic conditions, such as lower post-takeoff debt and inflation levels; more competitive real exchange rates; and better structural reforms and institutions. The chances of starting a takeoff in the 2000s was triple that before the 1990s, with domestic conditions accounting for most of the increase. The findings suggest that if today’s dynamic developing economies sustain their improved policies; they are more likely to stay on course compared to many of their predecessors.

Fixing the Fixings: What Road to a More Representative Money Market Benchmark?
Description: Interest rate derivatives on major currencies, with notional outstanding amounts adding up to hundreds of trillions, are mostly indexed on Libor and Euribor benchmarks, as are hundreds of billions in loans to enterprises, mortgages and other retail loans to the real economy. Yet, the prevailing role of these benchmarks appears to be more a legacy from history rather than reflecting today?s structure of banks? funding. Building on earlier work (Brousseau, Chailloux, Durré, 2009), this paper discusses various options to move towards a new benchmarking system in the money market. It proposes a more ambitious benchmark design that would consist of a trade-weighted index that would systematically pool all short-term wholesale funding operations of banks per tenor.

The Finance and Growth Nexus Re-Examined: Do All Countries Benefit Equally?
Description: A large theoretical and empirical literature has focused on the impact of financial deepening on economic growth throughout the world. This paper contributes to the literature by investigating whether this impact differs across regions, income levels, and types of economy. Using a rich dataset for 150 countries for the period 1975–2005, dynamic panel estimation results suggest that the beneficial effect of financial deepening on economic growth in fact displays measurable heterogeneity; it is generally smaller in oil exporting countries; in certain regions, such as the Middle East and North Africa (MENA); and in lower-income countries. Further analysis suggests that these differences might be driven by regulatory/supervisory characteristics and related to differences in the ability to provide widespread access to financial services.

Taxing Immovable Property Revenue Potential and Implementation Challenges
Description: The tax on immovable property has been characterized as probably the most unpopular among tax instruments, in part because it is salient and hard to avoid. But economists continue to emphasize the virtues of the property tax owing to its relatively low efficieny costs, benign impact on growth, and high score on fairness. It is, therefore, generally considered to be underutilized in most countries. This paper takes stock of the arguments for using real property taxation, and presents an updated data-set for high-and middle income countries to illustrate its use. It also reflects the renewed and widespread interest in property tax reform globally, and discusses the many policy and administrative issues that must be carefully considered as prerequisites for successful property tax reform.
