SME Financial Inclusion for Sustained Growth in the Middle East and Central Asia

Description: This paper offers empirical evidence that greater financial inclusion of small and medium enterprises (SMEs) can promote higher economic growth and employment, especially in the Middle East and Central Asia regions. First, we show that countries with higher SME financial inclusion exhibit more effective monetary policy transmission and tax collection. Second, we find substantial employment and labor productivity growth gains at the firm level from access to credit, gains that are higher for SMEs. We also obtain evidence of a substantial positive impact on SME employment and labor productivity growth from improved credit bureau coverage and insolvency regimes. Finally, cross-country aggregate evidence confirms the employment and growth gains from SME financial inclusion, which appear larger in the Middle East and Central Asia than in other regions.

What Happens if Central Banks Misdiagnose a Slowdown in Potential Output

Description: In the last few decades, real GDP growth and investment in advanced countries have declined in tandem. This slowdown was not the result of weak demand (there has been no shift along the Okun curve), but of a decline in potential output growth (which has shifted the Okun curve to the left). We analyze what happens if central banks mistakenly diagnose the problem as insufficient demand, when it is actually a supply problem. We do this in a real model, in which inflation is not an issue. We show that aggressive central bank action may revive gross investment, but it will not revive net investment or growth. Moreover, low interest rates will lead to an increase in the capital output ratio, a low return on capital and high leverage. We show that these forecasts are in line with what has happened in major advanced countries.

The Riskiness of Credit Allocation and Financial Stability

Description: We explore empirically how the time-varying allocation of credit across firms with heterogeneous credit quality matters for financial stability outcomes. Using firm-level data for 55 countries over 1991-2016, we show that the riskiness of credit allocation, captured by Greenwood and Hanson (2013)’s ISS indicator, helps predict downside risks to GDP growth and systemic banking crises, two to three years ahead. Our analysis indicates that the riskiness of credit allocation is both a measure of corporate vulnerability and of investor sentiment. Economic forecasters wrongly predict a positive association between the riskiness of credit allocation and future growth, suggesting a flawed expectations process.

Private Sector Job Creation in MENA: Prioritizing the Reform Agenda

Description: This paper examines the extent to which firms in selected MENA countries reported being constrained by the business environment around the time of the Arab Spring and the extent to which these constraints affected their employment performance. The results suggest that small firms in MENA faced more structural constraints than similar firms in other regions. We also find that MENA firms’ weaker job creation can be explained in great part by the macroeconomic environment and structural constraints. Low GDP growth, falling external competitiveness, corruption, lack of access to finance and poor access to electricity are found to explain a significant part of the lack of employment growth in MENA firms compared to their peers.

Multiple Dimensions of Human Development Index and Public Social Spending for Sustainable Development

Description: Multidimensional assessment of human development is increasingly recognized as playing an important role in assessing well-being. The focus of analysis is on the indicators measuring the three dimensions of Human Development Index (HDI) — standard of living, education and health, and their relationship with public social spending for achieving the 2030 Agenda for Sustainable Development. The study estimates the effects of public social spending on gross national income (GNI) per capita (in PPP in $), expected years of schooling and life expectancy for a sample of 68 countries. The relationship is robust to controlling for a variety of factors and the estimated magnitudes suggest a positive long-run effect of public educational spending on GNI per capita, public educational spending on expected years of schooling, and public health expenditures on life expectancy.

How Should We Measure City Size Theory and Evidence Within and Across Rich and Poor Countries

Description:

It is obvious that holding city population constant, differences in cities across the world are enormous. Urban giants in poor countries are not large using measures such as land area, interior space or value of output. These differences are easily reconciled mathematically as population is the product of land area, structure space per unit land (i.e., heights), and population per unit interior space (i.e., crowding). The first two are far larger in the cities of developed countries while the latter is larger for the cities of developing countries. In order to study sources of diversity among cities with similar population, we construct a version of the standard urban model (SUM) that yields the prediction that the elasticity of city size with respect to income could be similar within both developing countries and developed countries. However, differences in income and urban technology can explain the physical differences between the cities of developed countries and developing countries. Second, using a variety of newly merged data sets, the predictions of the SUM for similarities and differences of cities in developed and developing countries are tested. The findings suggest that population is a sufficient statistic to characterize city differences among cities within the same country, not across countries.

One Ring to Rule Them All? New Evidence on World Cycles

Description: We estimate world cycles using a new quarterly dataset of output, credit and asset prices assembled using IMF archives and covering a large set of advanced and emerging economies since 1950. World cycles, both real and financial, exist and are generally driven by US shocks. But their impact is modest for most countries. The global financial cycle is also much weaker when looking at credit rather than asset prices. We also challenge the view that syncronization has increased over time. Although this is true for prices (goods and assets), this not true for quantities (output and credit). The world business and credit cycles were as strong during Bretton Woods (1950–1972) as during the Globalization period (1984-2006). For most countries, the way their output co-moves with the rest of the world has changed little over the last 70 years. We discuss the reasons behind these new findings and their policy implications for small open economies.

More Gray, More Volatile? Aging and (Optimal) Monetary Policy

Description: The evidence on the inflation impact of aging is mixed, and there is no evidence regarding the volatility of inflation. Based on advanced economies’ data and a DSGE-OLG model, we find that aging leads to downward pressure on inflation and higher inflation volatility. Our paper is also the first, using this framework, to discuss how aging affects the transmission channels of monetary policy. We are also the first to examine aging and optimal central bank policies. As aging redistributes wealth among generations and the labor force becomes more scarce, our model suggests that aging makes monetary policy less effective and in more gray societies central banks should react more strongly to nominal variables.

Is Military Spending Converging Across Countries? An Examination of Trends and Key Determinants

Description: This paper studies the evolution of worldwide military spending during 1970-2018. It finds that military spending in relation to GDP is converging, but into three separate groups of countries. In the largest group, responsible for 90 percent of worldwide spending, outlays have remained stubbornly high. Military spending in developing economies reacts to improvements in security conditions and military spending in neighboring countries, suggesting that further increases in the peace dividend are possible. In developing economies, rising social spending tends to crowd out military outlays, but this is not the case in advanced economies. With social outlays projected to rise as developing countries look to achieve the Sustainable Development Goals (SDGs), military spending could come under pressure to fall further.
