Repeated Use of IMF-Supported Programs: Determinants and Forecasting
Description: This paper studies the determinants of repeated use of Fund-supported programs in a large sample covering virtually all General Resources Account (GRA) arrangements that were approved between 1952 and 2012. Generally, the revolving nature of the IMF’s resources calls for the temporary sup-port of member countries to address balance of payments problems while repeated use has often been viewed as program failure. First, using probit models we show that a small number of country-specific variables such as growth, the current account balance, the international reserves position, and the institutional framework play a significant role in explaining repeated use. Second, we discuss the role of IMF-specific and program-specific variables and find evidence that a country’s track record with the Fund is a good predictor of repeated use. Finally, we conduct an out-of-sample forecasting exer-cise. While our approach has predictive power for repeated use, exact forecasting remains challenging. From a policy perspective, the results could prove useful to assess the risk IMF programs pose to the revolving nature of the Fund’s financial resources.

The Drivers, Implications and Outlook for China’s Shrinking Current Account Surplus
Description: China’s current account surplus has declined significantly from its peak in 2008 and the external position in 2018 was in line with medium-term fundamentals and desirable policies. While cyclical factors and expansionary credit and fiscal policies contributed, the trend decline has been largely structural, driven by economic rebalancing from investment to consumption, appreciation of the real effective exchange rate (REER) towards equilibrium, increase in outbound tourism, and moderation in goods surplus reflecting market saturation and China’s faster growth compared with trading partners. Policies should focus on continued rebalancing and opening up to ensure excessive surpluses do not return, and to prepare the economy and the financial system to handle more volatile capital flows. From a global perspective, the decline in China’s surplus has lowered global imbalances, but with different impact across countries. The analysis is based on data as of July 2019.

Structural Unemployment in Luxembourg: Bad Luck or Rational Choice?
Description: This paper combines both micro and macro approaches to identify the drivers of (un)employment and inactivity in Luxembourg. The young, low-skilled, and non-EU migrants are found to be the most vulnerable groups in the labor market. In addition to skills mismatches, work disincentives embedded in the tax-benefit system constitute a factor explaining structural unemployment. High unemployment of young and low-skilled workers reflects substantial unemployment traps, while disincentives for second earners (respectively the generosity of the pension system) contribute to lower labor market participation of women (respectively seniors). Further reduction of structural unemployment requires better integration of vulnerable groups into the labor market and improved targeting of benefits to make work more rewarding.

Back to the Future: Fiscal Rules for Regaining Sustainability
Description: This paper assesses the cyclicality and sustainability of fiscal policy in Belize and applies a stochastic simulation model to determine the optimal set of fiscal rules. The empirical analysis shows that fiscal policy in Belize has been significantly procyclical and unsustainable much of the period since 1976. While the government’s recent commitment to maintain a primary surplus of at least 2 percent of GDP until 2021 is supporting debt reduction, stochastic simulations indicate that further improvement in the primary balance is necessary to reliably bring the debt-to-GDP ratio to a sustainable path. Given Belize’s history of large economic shocks, this paper proposes explicit fiscal rules designed for countercyclical policy and debt sustainability. It recommends integrating such rules into a well-designed fiscal responsibility law and establishing an independent fiscal council to improve accountability and transparency.

Doing More with Less: How Can Brazil Foster Development While Pursuing Fiscal Consolidation?
Description: Following a benchmarking exercise, we estimate the spending required to reach satisfactory progress in the Sustainable Development Goals in the health, education, and infrastructure sectors in Brazil. We find that there is room for savings in education (up to 1.5 percentage point of GDP) and health (up to 2.5 percentage points of GDP) without compromising the quality of services but additional investments for over 3 percent of GDP per year are needed to close large infrastructure gaps in roads, water, and electricity by 2030. Brazil can do more with less, but increasing efficiency of public spending will require substantial reforms.

German Bond Yields and Debt Supply: Is There a “Bund Premium”?
Description: Are Bunds special? This paper estimates the “Bund premium” as the difference in convenience yields between other sovereign safe assets and German government bonds adjusted for sovereign credit risk, liquidity and swap market frictions. A higher premium suggests less substitutability of sovereign bonds. We document a rise in the “Bund premium” in the post-crisis period. We show that there is a negative relationship of the premium with the relative supply of German sovereign bonds, which is more pronounced for higher maturities and when risk aversion proxied by bond market volatility is high. Going forward, we expect German government debt supply to remain scarce, with important implications for the ECB’s monetary policy strategy.

International Bank Lending Channel of Monetary Policy
Description: How does domestic monetary policy in systemic countries spillover to the rest of the world? This paper examines the transmission channel of domestic monetary policy in the cross-border context. We use exogenous shocks to monetary policy in systemically important economies, including the U.S., and local projections to estimate the dynamic effect of monetary policy shocks on bilateral cross-border bank lending. We find robust evidence that an increase in funding costs following an exogenous monetary tightening leads to a statistically and economically significant decline in cross-border bank lending. The effect is weakened during periods of high uncertainty. In contrast, the effect is found to not vary according to the degree of borrower country riskiness, further weakening support for the international portfolio rebalancing channel.

On the Substitution of Private and Public Capital in Production
Description: Most macroeconomic models assume that aggregate output is generated by a specification for the production function with total physical capital as a key input. Implicitly this assumes that private and public capital stocks are perfect substitutes. In this paper we test this assumption by estimating a nested-CES production function whereas the two types of capital are considered separately along with labor as inputs. The estimation is based on our newly developed dataset on public and private capital stocks for 151 countries over a period of 1960-2014 consistent with Penn World Table version 9. We find evidence against perfect substitutability between public and private capital, especially for emerging and LIDCs, with the point estimate of the elasticity of substitution estimated closely around 3.

Achieving the Bank of Japan’s Inflation Target
Description: The Bank of Japan has introduced various unconventional monetary policy tools since the launch of Abenomics in 2013, to achieve the price stability target of 2 percent inflation. In this paper, a forward-looking open-economy general equilibrium model with endogenously determined policy credibility and an effective lower bound is developed for forecasting and policy analysis (FPAS) for Japan. In the model’s baseline scenario, the likelihood of the Bank of Japan reaching its 2 percent inflation target over the medium term is below 40 percent, assuming the absence of other policy reactions aside from monetary policy. The likelihood of achieving the inflation target is even lower under alternative risk scenarios. A positive shock to central bank credibility increases this likelihood, and would require less accommodative macroeconomic policies.

Machine Learning and Causality: The Impact of Financial Crises on Growth
Description: Machine learning tools are well known for their success in prediction. But prediction is not causation, and causal discovery is at the core of most questions concerning economic policy. Recently, however, the literature has focused more on issues of causality. This paper gently introduces some leading work in this area, using a concrete example—assessing the impact of a hypothetical banking crisis on a country’s growth. By enabling consideration of a rich set of potential nonlinearities, and by allowing individually-tailored policy assessments, machine learning can provide an invaluable complement to the skill set of economists within the Fund and beyond.
