Immigration and Employment: Substitute Versus Complementary Labor in Selected African Countries
Description: This paper uses census and household survey data on Cameroon, Ghana, and South Africa to examine immigration’s impact in the context of a segmented labor market in Sub-Saharan Africa. We find that immigration affects (i) employment (ii) employment allocation between informal and formal sectors, and (iii) the type of employment within each sector. The direction of the impact depends on the degree of complementarity between immigrants and native workers’ skills. Immigration is found to be productivity-enhancing in the short to near term in countries where, the degree of complementarity between immigrants and native workers’ skill sets is the highest.

Accounting Standards and Insurer Solvency Assessment
Description: The paper explores the use of accounting standards for insurer solvency assessment in the context of the implementation of IFRS 17. The paper is based on the results of a survey of 20 insurance supervisors. Overall, IFRS 17 is a welcome development but there will be challenges of implementation. Not many insurance supervisors currently intend to use IFRS 17 as a basis for solvency assessment of insurers. Perceived shortcomings can be overcome by supervisors providing clear specifications where the principles-based standard allows a range of approaches. Accounting standards can provide a ready-made valuation framework for supervisors developing new solvency frameworks.

A Framework for Estimating Health Spending in Response to COVID-19
Description: We estimate the additional health spending necessary to treat COVID-19 patients. We expand a Susceptible Infected Recovered model to project the number of people requiring hospitalization, use information about healthcare costs by country, and make assumptions about capacity constraints in the health sector. Without social distancing and lockdowns, countries would need to expand health systems ten-fold, on average, to assist all COVID-19 patients in need of hospitalization. Under capacity constraints, effective social distancing and quarantine reduce the additional health spending from a range of $0.6–1 trillion globally to $130–231 billion, and the fatality rate from 1.2 to 0.2 percent, on average.

Network Effects and Research Collaborations
Description: We study the determinants of new and repeated research collaborations, drawing on the co-authorship network of the International Monetary Fund (IMF)’s Working Papers series. Being an outlet where authors express their views on topics of interest, and given that IMF staff is not subject to the “publish-or-perish” conditions of the academia, the IMF Working Papers series constitutes an appropriate testing ground to examine the endogenous nature of co-authorship formation. We show that the co-authorship network is characterized by many authors with few direct co-authors, yet indirectly connected to each other through short co-authorship chains. We find that a shorter distance in the co-authorship network is key for starting research collaborations. Also, higher research productivity, being employed in the same department, and having citizenship of the same region help to start and repeat collaborations. Furthermore, authors with different co-authorship network sizes are more likely to collaborate, possibly reflecting synergies between senior and junior staff members.

Tax Revenues in Fragile and Conflict-Affected States—Why Are They Low and How Can We Raise Them?
Description: Raising revenues has been a formidable challenge for fragile and conflict-affected states (FCS), a fact confirmed once again in the COVID-19 crisis. Nonetheless, achieving sizable gains in tax collection in fragile environments is not impossible. This paper—with empirical analyses and case studies—contributes to policy discussions on tax reform in such challenging environments. Our analyses show that many FCS achieved some recovery of tax revenues, even though they found it challenging to sustain the momentum beyond three years. We also find that changes in the quality of institutions (e.g., government effectiveness and control of corruption) are a key contributory factor to their tax performance (much more so than for non-FCS). Next, we look into the tax increase episodes of four countries (Liberia, Malawi, Nepal, and the Solomon Islands). Although each FCS is unique, their experiences suggest two lessons: (i) tax reforms can be pursued even with initially weak institutions; and (ii) strong political commitment is important to sustain reform efforts and realize long-lasting, sizable gains.

Raising Tax Revenue: How to Get More from Tax Administrations?
Description: Can we empirically show the benefits of improving the practices and characteristics of tax administration agencies for revenue collection? While many country experiences suggest a strong link, there is little systematic empirical evidence on the matter. This paper analyzes the association between tax collections and tax administrations, using the novel dataset (ISORA). We find that tax performance is positively and strongly associated with the operational strength of tax administrations. Among emerging and low-income economies, countries at the top 25 percent (in terms of the operational strength) collect substantially larger tax revenues (by 3¼ percent of GDP) than countries at the lowest 25 percent, assuming other conditions are equal. Our results also suggest that adopting key administrative practices such as compliance risk management and use of third-party data is associated with stronger tax collections. Furthermore, larger staffing of a tax agency improves tax revenue up to a point. These findings have important policy implications, particularly during the unprecedented global pandemic situation.

Who Drains Bond Market Liquidity in an Emerging Market?
Description: This paper examines the drivers of liquidity shortages in the Mexican government bond market. We use unique transaction- and quote level data with information on end-investors to construct an index of bond market liquidity. We find that liquidity remained stable in recent years, although temporary shortages arose amid domestic and global market stress. The analysis suggests that the largest liquidity squeezes have tended to be driven by foreign investors, whose sell-offs were especially pronounced in less liquid market segments. While domestic banks often absorbed part of the shock, other domestic investors—with the notable inclusion of domestic pension and mutual funds—appeared to take a more opportunistic stance depending on the nature of the shock.

Forbearance Patterns in the Post-Crisis Period
Description: Using supervisory loan-level data on corporate loans, we show that banks facing high levels of non-performing loans relative to their capital and provisions were more likely to grant forbearance measures to the riskiest group of borrowers. More specifically, we find that risky borrowers are more likely to get an increase in the overall limit or the maturity of a loan product from a distressed lender. As a second step, we analyse the effectiveness of this practice in reducing the probability of default. We show that the most common measure of forbearance is effective in the short run but no forbearance measure significantly reduces the probability of default in the long run. Our evidence also suggests that forbearance and new lending are substitutes for banks, as high shares of forbearance are negatively correlated with new lending to the same group of borrowers. Taken together, these findings can help policy makers shape surveillance and regulation in a future recovery from the Covid-19 pandemic.

Reading the Stars
Description: Following the global financial crisis, significant uncertainty has existed around the U.S. economy’s steady state equilibrium. This paper uses a factor model to provide a new approach to estimating “the stars” (i.e. the neutral interest rate, maximum employment, and the level and growth rate of potential output) that are most consistent with a medium-term equilibrium where inflation converges to the FOMC’s two percent target. It is applicable to any country with an inflation targeting central bank. It also explicitly incorporates estimates of the extensive margin of slack in the labor market, which has proven to be an important factor in describing the post-financial crisis landscape.

Harnessing Digital Technologies to Promote SMEs in the MENAP Region
Description: Policy makers in the MENAP region have been formulating policies and designing programs to develop small and medium sized enterprises (SMEs) with a view to create jobs and achieve inclusive growth. But while the programs have helped increase the number of enterprises, growth of SMEs continues to face barriers to growth. As a result, microenterprises predominate and SMEs contribution to employment remains below potential. Partial implementation of reforms explain some of the underperformance, but frictions in strategy design also played an important role. Sustaining current reforms is, therefore, not sufficient to achieve inclusive growth. Digital technologies have potential to boost SMEs productivity and growth and economies are rapidly digitalizing, thus SMEs need to embrace digital solutions to compete and survive. Therefore, for SMEs to be effective engines of inclusive growth, a rethinking of the SME development strategy is needed that makes SMEs’ digital transformation a priority.
