Inequality in China – Trends, Drivers and Policy Remedies
Description: China has experienced rapid economic growth over the past two decades and is on the brink of eradicating poverty. However, income inequality increased sharply from the early 1980s and rendered China among the most unequal countries in the world. This trend has started to reverse as China has experienced a modest decline in inequality since 2008. This paper identifies various drivers behind these trends – including structural changes such as urbanization and aging and, more recently, policy initiatives to combat it. It finds that policies will need to play an important role in curbing inequality in the future, as projected structural trends will put further strain on equity considerations. In particular, fiscal policy reforms have the potential to enhance inclusiveness and equity, both on the tax and expenditure side.

Labor Market Duality in Korea
Description: Labor market duality is a complex and critical issue for many countries that can lower productivity, contribute to inequality and result in negative externalities. In this paper, I study duality in the Korean labor market and analyze its sources and potential policy options. I find that employment protection legislations and large productivity differentials are the key drivers of Korea’s duality. In addition, applying a general equilibrium search-and-matching model and calibrating it to the Korean economy, I show that well-calibrated flexicurity policies can significantly reduce duality and inequality and raise welfare and productivity. Notably, the introduction of all three pillars—flexiblity, a strong safety net and active labor market policies—is critical for its success. If only one pillar is introduced it can result in negative side-effects and might not reduce duality.

Effectiveness of Internal Audit and Oversight at Central Banks: Safeguards Findings - Trends and Observations
Description: Experience under the safeguards policy has shown that central banks continued to strengthen their safeguards frameworks, but that vulnerabilities prevailed in the areas of internal audit and oversight by the audit committee (AC). This paper takes steps to help unravel why this was the case, based on analysis of safeguards findings in these areas during the period April 2010 to December 2017 (covering 111 assessments at 64 central banks). Based on this analysis, it presents the key attributes that determine the effectiveness of internal audit and the AC. It also argues that, an effective internal audit function, coupled with strong oversight by a high-performing AC are key enablers of good governance.

Empirical Estimation of Fiscal Multipliers in MENA Oil-Exporting Countries with an Application to Algeria
Description: At a time when Algeria must undertake considerable fiscal consolidation to restore sustainability, the issue of fiscal multipliers has come to the fore. This paper estimates short-term and long-term fiscal multipliers for Algeria applying several econometric methodologies, including Local Projection Methodology and Vector Autoregressive Models, and using both Algeria-specific and panel data. The paper also explores asymmetries related to the sign of the output gap as well as the direction of spending. The results suggest that (i) average fiscal multipliers for Algeria are generally moderate and below unity; (ii) the impact of public spending shocks is more important when the output gap is negative; (iii) fiscal spending multipliers are significantly larger during spending contraction than expansion; (iv) procyclicality in public spending does not appear to affect output, except for capital spending cuts when the output gap is negative; and (v) while multipliers associated with countercyclical public spending can be sizeable, a contraction in current spending does not materially affect non-oil GDP.

Does Financial Tranquility Call for Stringent Regulation?
Description: Consistent with the Minsky hypothesis and the “volatility paradox” (Brunnermeier and Sannikov, 2014), recent empirical evidence suggests that financial crises tend to follow prolonged periods of financial stability and investor optimism. But does financial tranquility always call for more stringent regulation over time? We examine this question using a simple portfolio choice model that features the interaction between learning and externality. We evaluate the potential of a macroprudential policy to restore efficiency, and characterize the necessary and sufficient condition for the countercyclicality of the optimal regulation/macroprudential policy. Our paper implies that policymakers should not only consider the cyclical indicators “on the surface” (for example, credit growth), but also closely examine the deep structural change of the resilience of the system. The paper also highlights the importance of assigning the macroprudential policy function to independent agencies with technical expertise.

On the Macroeconomic Consequences of Over-Optimism
Description: Is over-optimism about a country's future growth perspective good for an economy, or does over-optimism also come with costs? In this paper we provide evidence that recessions, fiscal problems, as well as Balance of Payment-difficulties are more likely to arise in countries where past growth expectations have been overly optimistic. To examine this question, we look at the medium-run effects of instances of over-optimism or caution in IMF forecasts. To isolate the causal effect of over-optimism we take an instrumental variables approach, where we exploit variation provided by the allocation of IMF Mission Chiefs across countries. As a necessary first step, we document that IMF Mission Chiefs tend to systematically differ in their individual degrees of forecast-optimism or caution. The mechanism that transforms over-optimism into a later recession seems to run through higher debt accumulation, both public and private. Our findings illustrate the potency of unjustified optimism and underline the importance of basing economic forecasts upon realistic medium-term prospects.

Belize's 2016-17 Sovereign Debt Restructuring - Third Time Lucky?
Description: This paper examines the causes, processes, and outcomes of Belize’s 2016–17 sovereign debt restructuring—its third episode in last 10 years. As was the case in the earlier two restructurings, in 2006–07 and in 2012–13, the 2016–17 debt restructuring was executed through collaborative engagement with creditors outside an IMF-supported program. While providing liquidity relief and partially addressing long-term debt sustainability concerns, the restructuring will need to be underpinned by ambitious fiscal consolidation and growth-enhancing structural reforms to secure durable gains.

A Cohort-Based Analysis of Labor Force Participation for Advanced Economies
Description: Advanced economies are in the midst of a major demographic transition, with the number of elderly rising precipitously relative to the working-age population. Yet, despite the acceleration in demographic shifts in the past decade, advanced economies experienced markedly different trajectories in overall labor force participation rates and the workforce attachment of men and women. Using a cohort-based model of labor force participation for 17 advanced economies estimated over the 1985-2016 period, we document a significant role of common patterns of participation over the life cycle and shifts in these patterns across generations for aggregate labor supply, especially in the case of women. The entry of new cohorts of women led to upward shifts in the age participation pro le, boosting aggregate participation rates. However, this process plateaued in most advanced economies, with signs of reversal in some. Using the model's results to forecast future participation trends, we project sizable declines in aggregate participation rates over the next three decades due to the aging of the population. Illustrative simulations show that implementing policies encouraging labor supply can help attenuate but may not fully offset demographic pressures.

Australia's Linkages with China: Prospects and Ramifications of China's Economic Transition
Description: China and Australia have increasingly strong links, especially through trade. These are driven by demand from China for Australian commodities (coal and iron ore) and services (tourism and education). These links are influenced by China’s transition to a services-driven, consumer-led economy. Using ANZIMF, the Australia-New Zealand Integrated Monetary and Fiscal model, three risks (both upside and downside) to China during this transition process are considered, focusing on their spillovers to Australia. One simple takeaway is central to each risk – while the real GDP response to shocks in Australia typically is small, responses in demand components or sectors are usually much larger– along with three further takeaways, all of which help in the analysis of Australia in relation to any risk emanating from China.

Should We Fear the Robot Revolution? (The Correct Answer is Yes)
Description: We may be on the cusp of a “second industrial revolution” based on advances in artificial intelligence and robotics. We analyze the implications for inequality and output, using a model with two assumptions: “robot” capital is distinct from traditional capital in its degree of substitutability with human labor; and only capitalists and skilled workers save. We analyze a range of variants that reflect widely different views of how automation may transform the labor market. Our main results are surprisingly robust: automation is good for growth and bad for equality; in the benchmark model real wages fall in the short run and eventually rise, but “eventually” can easily take generations.
