A Model-based Fiscal Taylor Rule and a Toolkit to Assess the Fiscal Stance
Description: This paper presents a model-based fiscal Taylor rule and a toolkit to assess the fiscal stance, defined as the change in the structural primary balance. This is built on the normative buffer-stock model of the government (Fournier, 2019) which includes key channels like hysteresis, cycle-dependent multipliers and a risk premium. A simple fiscal Taylor rule prescribes the fiscal stance as a function of past government debt, past output gap and the past structural primary balance. Applications suggest several advanced economies could have better managed their fiscal stance over the last 20 years. Simulations provide fiscal stance recommendations over the medium-term.

Taking Down the Wall: Transition and Inequality
Description: This paper investigates the main determinants of income inequality in transition countries during the period 1990–2018. To this end, we address a major methodological challenge that lies at the core of the cross-country literature on income inequality: the potential endogeneity of income growth, which is largely ignored by most empirical studies. We adopt a two-pronged empirical strategy by (i) using trading partners’ weighted average real GDP as an instrumental variable (IV), and (ii) estimating the model via the two-stage least squares (2SLS) approach for static models and the Generalized Method of Moments (GMM) estimator for dynamic models. Our empirical findings are consistent with the Kuznets curve that illustrates a nonlinear relationship between income inequality and the level of economic development. We also find that the redistributive impact of fiscal policy is statistically insignificant and taxation and government spending appear to have the opposing effects on income inequality in transition economies.

Vietnam's Development Success Story and the Unfinished SDG Agenda
Description: Despite starting as one of the poorest countries in the mid-1980s, Vietnam has achieved rapid developmental progress, reaching lower middle-income status in 2010. In line with rapid economic growth, Vietnam has achieved impressive progress towards the Sustainable Development Goals (SDGs) during this time. This paper sheds light on some elements of Vietnam’s success story, highlighting crucial policies in education and electricity sectors. It undertakes a forward-looking costing exercise that focusses on five sectors – education, health, roads, water, and electricity infrastructure. Achieving the remaining SDGs in Vietnam will be a challenge, with total annual additional spending needs in the 5 subsectors estimated at 7 percent of GDP by 2030.

Competition, Competitiveness and Growth in Sub-Saharan Africa
Description: Does greater product market competition improve external competitiveness and growth? This paper examines this question by using country-and firm-level data for a sample of 39 sub-Saharan African countries over 2000–17, as well as other emerging market economies and developing countries, and finds that an improvement in domestic competition is associated with a signficant increase in real GDP per capita growth rate, achieved mainly through an improvement in export competitiveness and productivity growth. Price levels, including of essential items, are also generally lowered with an increase in competition. Moreover, at the firm-level, evidence shows that greater competition—proxied through a decline in corporate market power—is associated with an increase in firm’s investment and the labor’s share in output. These effects are more pronounced in the manufacturing sector and among domestic firms compared to foreign firms.

Distributional Implications of Labor Market Reforms: Learning from Spain's Experience
Description: Spain’s structural reforms, implemented around 2012, have arguably contributed to a faster and stronger economic recovery. In particular, there is strong evidence that the 2012 labor market reforms increased wage flexibility, which helped the Spanish economy to regain competitiveness and create jobs. But the impact of these labor reforms on income inequality and social inclusion has not been analyzed much. This paper aims to shed light on this issue by employing an econometric decomposition procedure combined with the synthetic control method. The results indicate that the 2012 labor reforms have helped improve employment and income equality outcomes with no substantial impact on the overall risk of poverty. Nevertheless, the reforms appear to have induced a deterioration of average hours worked, in-work poverty, and possibly also of involuntary part-time employment.

Cyber Risk Surveillance: A Case Study of Singapore
Description: Cyber risk is an emerging source of systemic risk in the financial sector, and possibly a macro-critical risk too. It is therefore important to integrate it into financial sector surveillance. This paper offers a range of analytical approaches to assess and monitor cyber risk to the financial sector, including various approaches to stress testing. The paper illustrates these techniques by applying them to Singapore. As an advanced economy with a complex financial system and rapid adoption of fintech, Singapore serves as a good case study. We place our results in the context of recent cybersecurity developments in the public and private sectors, which can be a reference for surveillance work.

Does Child Marriage Matter for Growth?
Description: Global attention to ending child marriage and its socio-economic consequences is gaining momentum. Ending child marriage is not only critical from a development perspective but it also has important economic implications. This paper is the first to quantify the relationship between child marriage and economic growth. Applying a simultaneous equations model, the analysis shows that eliminating child marriage would significantly improve economic growth—if child marriage were ended today, long-term annual per capita real GDP growth in emerging and developing countries would increase by 1.05 percentage points. The results also provide insights on policy prioritization in developing comprehensive strategies to end child marriage. For example, the strong interdependent relationship between education and child marriage suggests that education policies and the budgets that support them should place greater emphasis on reducing child marriage.

Monetary Policy Implementation: Operational Issues for Countries with Evolving Monetary Policy Frameworks
Description: This paper discusses operational issues for countries that want to reform their monetary policy frameworks. It argues that stabilizing short-term interest rates on a day-to-day basis has significant advantages, and thus that short-term interest rates, not reserve money, in most cases should be the daily operating target, including for countries relying on a money targeting policy strategy. The paper discusses how a policy formulation framework based on monetary aggregates can be combined with an operational framework that ensures more stable and predictable short-term rates to enhance policy transmission. It also discusses how to best configure an interest-rate-based operational framework when markets are underdeveloped and liqudity management capacity is weak.

Macroeconomic Policy, Product Market Competition, and Growth: The Intangible Investment Channel
Description: While there is growing evidence of persistent or even permanent output losses from financial crises, the causes remain unclear. One candidate is intangible capital – a rising driver of economic growth that, being non-pledgeable as collateral, is vulnerable to financial frictions. By sheltering intangible investment from financial shocks, counter-cyclical macroeconomic policy could strengthen longer-term growth, particularly so where strong product market competition prevents firms from self-financing their investments through rents. Using a rich cross-country firm-level dataset and exploiting heterogeneity in firm-level exposure to the sharp and unforeseen tightening of credit conditions around September 2008, we find strong support for these theoretical predictions. The quantitative implications are large, highlighting a powerful stabilizing role for macroeconomic policy through the intangible investment channel, and its complementarity with pro-competition product market deregulation.

Measuring Output Gap: Is It Worth Your Time?
Description: We apply a range of models to the U.K. data to obtain estimates of the output gap. A structural VAR with an appropriate identification strategy provides improved estimates of output gap with better real time properties and lower sensitivity to temporary shocks than the usual filtering techniques. It also produces smaller out-of-sample forecast errors for inflation. At the same time, however, our results suggest caution in basing policy decisions on output gap estimates.
