_{The study explores the effects of data transparency on economic growth for developing economies over a unique time period - at the onset of the 2007-2009 global financial crisis and thereafter. Data transparency is defined as the timely production of credible statistics as measured by the Statistical Capacity Indicator. The paper finds that data transparency has a positive effect on real gross domestic product per capita during a period of considerable uncertainty. The estimates indicate an elasticity of the magnitude of 0.03 percent per year, which is much larger than the elasticity of trade openness and schooling in the estimation sample. The empirics employ a variety of econometric estimators, including dynamic panel and cross-sectional instrumental variables estimators, with the latter approach yielding a higher estimated elasticity. The findings are robust to the inclusion of several factors in addition to political institutions and exogenous commodity-price and external debt-financing shocks.}

_{This paper examines the Arab Republic of Egypt's labor market transition dynamics post¡ªArab Spring based on the two most recent rounds of the Egypt Labor Market Panel Survey conducted in 2012 and 2018. In addition to providing disaggregated-level analysis by examining labor market transitions by gender, education, and age groups, the paper provides a cross-country, cross-regional perspective by comparing Egypt's labor market transitions with Mexico's, relying on data from the Encuesta Nacional de Ocupaci¨®n y Empleo. To match the span of Mexico's transitions (which are measured over a one-year period) and Egypt's (which are measured over six years), the analysis uses Monte Carlo simulations of repeated discrete-time Markov chains. Based on these results, the Egyptian labor market appears to be highly rigid compared to the Mexican labor market, which instead shows a large degree of dynamism regardless of individual initial labor market states at baseline. Auxiliary regression analyses focusing on transitions to and from the dominant absorbing labor market states in Egypt¡ªpublic sector employment for both genders, nonparticipation for women, and the informal sector for men¡ªshow that having a post-secondary education is associated with a lower probability of remaining out of the labor force for women who were already out of the labor force at baseline, while being married at baseline is found to be a significant predictor for women to stay out of the labor force if they were already so. Among men, the better educated are found to be more likely to secure formal employment, be it in the public or private sector, and are more likely to keep their public formal jobs once they secure them.}

_{Despite a consensus that quality of care is critically deficient in low-income countries, few nationally representative studies provide comparable measures of quality of care across countries. To address this gap, we used nationally representative data from in-person administrations of clinical vignettes to measure the competence of 16 127 health care providers across 11 sub-Saharan African countries. Rather than large variations across countries, we found that 81% of the variation in competence is within countries and the characteristics of health care providers do not explain most of this variation. Professional qualifications¡ªincluding cadre and education¡ªare only weakly associated with competence: across our sample, one-third of nurses are more competent than the average doctor in the same country and one-quarter of doctors are less competent than the average nurse. Finally, while younger cohorts do tend to be more competent, perhaps reflecting improvements in medical education, it would take 25 decades of turnover to improve care by 10 percentage points, on average, if we were to rely on such improvements alone. These patterns necessitate a fundamentally different approach to health care human resource management, calling into question typical staffing policies based on qualifications and seniority rather than directly measured quality.}

_{In this paper the authors evaluate the impact of COVID-19 lockdown policies on Tunisia¡¯s supply chains. They estimate a Poisson Pseudo Maximum Likelihood model using data on bilateral imports for intermediate, capital, and final goods for the years 2019 and 2020 at the country¨Cmonth¨Cproduct level. Their results show that, overall, lockdowns in Tunisia¡¯s partner countries had a significant and negative effect on imports made under both offshore and onshore regimes. Specifically, they observe a considerable fall in imports of intermediate and final goods under the offshore regime, which primarily involves firms producing goods for export and having a higher level of integration in global value chains. Additionally, all types of imports made under the onshore regime were affected by exporter lockdowns. Their results also reveal a certain heterogeneity related to some specific product and product¨Ccountry characteristics.}

_{Sub-Saharan Africa has fewer medical workers per capita than any region of the world, and that shortage has been highlighted consistently as a critical constraint to improving health outcomes in the region. This paper draws on newly available, systematic, comparable data from 10 countries in the region to explore the dimensions of this shortage. We find wide variation in human resources performance metrics, both within and across countries. Many facilities are barely staffed, and effective staffing levels fall further when adjusted for health worker absences. However, caseloads¡ªwhile also varying widely within and across countries¡ªare also low in many settings, suggesting that even within countries, deployment rather than shortages, together with barriers to demand, may be the principal challenges. Beyond raw numbers, we observe significant proportions of health workers with very low levels of clinical knowledge on standard maternal and child health conditions. This study highlights that countries may need to invest broadly in health workforce deployment, improvements in capacity and performance of the health workforce, and on addressing demand constraints, rather than focusing narrowly on increases in staffing numbers.}

_{A wealth of evidence has shown the positive effects of better management practices on firms. More recent evidence has highlighted that ownership matters for several developing and advanced economies. However, this relationship has not been studied extensively for economies in the Middle East and North Africa (MENA), a region where the presence of the government in the productive sphere looms large. This study addresses a gap in the literature by exploring how partial government ownership can influence management practices of medium and large formal firms in the MENA. Using two waves of Enterprise Surveys undertaken in 2013 and 2019/2020, the evidence points at a negative relationship between partial government ownership and management practices in the developing MENA region. The findings pass several robustness checks.}

_{This paper examines the role of a country's data transparency in explaining gross domestic product growth forecast errors. It reports four sets of results that have not been previously reported in the existing literature. First, forecast errors¡ªthe difference between forecasted and realized gross domestic product growth¡ªare large. Globally, between 2010 and 2020, the average same-year forecast error was 1.3 percentage points for the World Bank's forecasts published in January of each year, and 1.5 percentage points for the International Monetary Fund's January forecasts. Second, the Middle East and North Africa region has the largest forecast errors compared to other regions. Third, data capacity and transparency significantly explain forecast errors. On average, an improvement in a country's Statistical Capacity Index, a measure of data capacity and transparency, is associated with a decline in absolute forecast errors. A one standard deviation increase in the log of the Statistical Capacity Index is associated with a decline in absolute forecast errors by 0.44 percentage point for World Bank forecasts and 0.49 percentage point for International Monetary Fund forecasts. The results are robust to a battery of control variables and robustness checks. Fourth, the role of the overall data ecosystem, not just those elements related to gross domestic product growth forecasting, is important for the accuracy of gross domestic product growth forecasts. Finally, gross domestic product growth forecasts from the World Bank are more accurate and less optimistic than those from the International Monetary Fund and the private sector.}

_{Studies have noted that output per worker varies enormously across countries. Using firm-level survey data, the present paper contributes to the related literature by analyzing difference in labor productivity between firms in 22 upper middle-income and 11 high-income countries. Labor productivity in upper-middle-income countries is about 57.5% lower than in high-income countries. The Oaxaca-Blinder decomposition analysis of the productivity gap reveals that the gap is somewhat larger due to differences in the level of contributory factors (endowment effect) than due to differences in the returns to such factors (structural effect). That is, 55.2% of the productivity gap is due to endowment effect and the remaining 44.8% is due to structural effect. The biggest contributors via the endowment effect include tertiary education attainment, law and order, and quality management. Factors that contribute most via the structural effect include secondary education attainment, market size, and law and order. Thus, our results underline the importance of human capital, institutions and market size for the upper middle-income countries aspiring to become high-income countries.}

_{The benefits of formal training are numerous, and yet in many regions few firms utilize them. This study builds on the literature by exploring how two forms of human capital¡ªthe quality of management practices and the proportion of university educated employees¡ªinfluence the adoption of formal training. Using both cross-sectional and panel firm-level data for 29 economies in Eastern Europe and Central Asia and six economies in the Middle East and North Africa, the study finds that firm management practices are positively correlated with the implementation of formal training in Eastern Europe and Central Asia but not in the Middle East and North Africa. The proportion of university educated workers is positively correlated with formal training in both regions, but the finding is more robust for the Middle East and North Africa. These findings imply significant heterogeneity across regions in the determinants of formal training, suggesting that policies should be context specific.}

_{This article studies the impact of the COVID-19 pandemic on men's labour supply in the West Bank and Gaza, both on the extensive (participation) and intensive (hours of work) margins. We find that the pandemic was associated with a decline in employment and labour supply in the immediate aftermath of the pandemic, with large adjustments at the intensive margin. Afterwards, labour market indicators quickly bounced back to their pre-pandemic levels, but less so for the most vulnerable segments of the workforce, such as informal workers, workers in blue collar occupations, the least educated, and residents in refugee camps}

_{This article examines fertility and labor supply responses to a 2014 French policy reform that consisted of conditioning the amount of child allowances on household income. Employing regression discontinuity design and French administrative income data, I find that restricting family allowance eligibility criteria decreases fertility among the richest households. The results also highlight that receiving half the amount of the allowances or none leads to an increase in both male and female labor supply through an increase in overtime work. The implied change in earned income, due to an increase in weekly working hours, is found to be comparable to the euro value reduction in benefits. Auxiliary regression analyses show that the fertility decline reflects a decrease in the probability of having an additional child for parents rather than in the probability of becoming parents for households without children.}

_{This study uncovers a gender labor productivity gap among informal firms in 14 developing economies. The mean labor productivity of women-owned informal firms is approximately 15.6 percent (0.17 log points) lower than that of men-owned informal firms. The difference in productivity is larger at the lower quantiles of the labor productivity distribution than at the higher quantiles. The Kitagawa-Oaxaca-Blinder and quantile decomposition methods are used to estimate the aggregate ¡°endowment¡± vs ¡°structural¡± effects, and individual factors¡¯ contribution to the productivity gap. Several policy-relevant findings are revealed. First, the labor productivity gap at the mean is significantly larger due to lower education, prior work experience, capitalization, and less protection from crime among women than men owners of informal firms. The smaller size of the women-owned firms and their higher return from operations under contracts narrow the mean productivity gap. Second, the productivity gap at the mean and different labor productivity quantiles can be substantially narrowed by providing more resources to women owners of informal firms, such as education, managerial experience, and physical capital, without improvements in their returns to women-owned informal businesses. Third, overall, there is evidence of ¡°sticky floors¡± for women owners, but not ¡°glass ceilings¡±. Fourth, there is heterogeneity in the contribution of individual factors to the productivity gap at different quantiles of the labor productivity distribution. Targeting policies to the relevant quantiles will improve their effectiveness. Fifth, there are important similarities and differences between groups of countries in low-income Africa, middle-income Africa, and Latin America, as far as the gender labor productivity gap and its drivers are concerned. Thus, an eclectic policy approach is needed, combining the broader findings of the literature with the prevailing local conditions. Last, the data do indicate that a majority of women- and men-owned informal businesses would like to formalize.}

_{This paper examines the impact of massive refugee inflows on the mobility patterns of host communities. We rely on panel data from before and after the Syrian war and exploit the geographical distribution of Syrians across Jordanian subdistricts. Using difference in differences, we find that native outflows of the camp-hosting areas increased by 27%. This increased residential mobility out of the camp-hosting areas seems to be triggered by an increase in rents and a crowding out of Jordanian students by Syrians in schools. Our results also show that the Syrian presence increased Jordanians¡¯ job location mobility into the camp areas.}

_{Using firm-level survey data for 29,962 manufacturing firms in 141 developing and emerging countries, the impact of exports (as a percentage of sales) on the share of female workers at the firm is estimated. The impact is positive, large, and statistically significant. For the baseline specification, moving from a firm that does not export to one that does all its sales abroad is associated with a 6.6 percentage point increase in the share of female workers. This positive relationship is much stronger when competition in the domestic markets is low, social attitudes and mobility laws are more favorable to women's work outside the home, and the law-and-order situation is better. We argue that these heterogeneities serve as important checks against endogeneity concerns. We also provide results using the average share of exports in a country¨Cindustry cell as an instrument. The policy implications of our findings are discussed in detail.}

_{The authors consider how fears of model misspecification on the part of the planner and/or the households affect welfare gains from optimal macroprudential  in an economy with occasionally binding collateral constraints. In this setup, the decentralized equilibrium may differ from the social planner's equilibrium both because of the pecuniary externalities associated with the collateral constraint and because of the paternalistic imposition of the planner's beliefs when designing policy. When robust agents have doubts about the model, they create endogenous worst-case beliefs by assigning a high probability to low-utility events. The ratio of worst-case beliefs of the planner over the household's captures the degree of paternalism. The authors show that this novel channel could render the directions of welfare gains from a policy intervention ambiguous. However, their quantitative results suggest that doubts about the model need to be large to make a ¡°laissez-faire regime¡± better than an intervention regime.}

We use 2006 data from the World Bank Enterprise Surveys, the sub-national Human Development Index and the World Health Organization which covers 10 countries in Latin America. We estimate Instrumental Variables regression models. We find that CSR declaration increases the probability of adopting community programs leading to a small, but significant, positive effect on education at the subnational level. Also, CSR declaration has no significant impact on our pollution measure, particulate matter, even when CSR increases the probability of adopting environmental programs.}

_{This article contributes to better understanding firms¡¯ behavior in the presence of gender discriminatory laws and its linkages with labor market outcomes for women in a developing country setting. Using data collected through the World Bank Enterprise Surveys in the Democratic Republic of Congo, the study documents the existence of nonnegligible employer discrimination in the presence of discriminatory laws. Interestingly, discriminatory behaviors, and the related limitations in women¡¯s autonomy, are more pervasive outside the capital city, Kinshasa, which suggests that differences in enforcement and social norms may be at play. The study also finds that, in those firms that do not enforce discriminatory laws, women benefit from better labor market outcomes, in terms of their representation among the upper echelons of management and their participation in the overall workforce. The positive relationship between nondiscriminatory behaviors and female employment is particularly strong in the manufacturing sector.HIGHLIGHTS In the Democratic Republic of Congo, discriminatory laws are linked to employer discrimination against women.Firms do not follow these laws uniformly, with enforcement varying by geography and type of law.This important nuance helps uncover the interaction between national laws and local norms.Firms that do not impose discriminatory laws have more women employees and managers.}

_{Public debt in developing economies rose at a fast clip during 2020¨C21, at least partly due tothe onset of the global Covid-19 pandemic. Nobel laureate Paul Krugman opined in early 2021 that ¡°fighting covid islike fighting a war.¡± This paper argues that the Covid-19 pandemic shares many traits with natural disasters, exceptfor the global nature of the pandemic shock. This paper empirically examines trends in debt and economic growtharound the onset of three types of calamities, namely natural disasters, armed conflicts, and external-debtdistress in developing countries. The estimations provide quantitative estimates of differences in growth and debttrends in economies suffering episodes of calamities relative to the trends observed in economies notexperiencing calamities. The paper finds that debt and growth evolve quite differently depending on the type ofcalamity. The evidence indicates that public debt and output growth tend to rise faster after natural disasters than inthe counterfactual scenario without disasters, thus illustrating how debt-financed fiscal expansions can helpeconomic reconstruction. The findings are different for episodes of debt distress defined as periods of debtrestructuring, however. Economies experiencing debt distress are associated with growth trends that are on average belowthe growth rates of unaffected economies prior to and after the beginning of an episode of debt restructuring.}

_{The Covid-19 pandemic, followed by financial tightening due inflationary pressure, has raised public debt in developing economies as governments grapple with public health investments to curb the pandemic and collapse in revenues due to slower economic activity. The rise in debt may further disrupt the formal private sector in developing economies. Using two to three waves of panel firm-level data across developing economies, this study finds that higher public debt is correlated with low investment by formal private sector firms. The finding is largely driven by small and medium-size enterprises, domestic firms, and non-exporters ¡ª raising concerns about the distributional impacts. Potential channels are uncovered. High levels of debt reduced the accessibility of finance for private sector firms, limiting investment. Furthermore, a regulatory channel is observed. As public debt rises, firms spend more time with regulatory and tax officials, which is possibly indicative of higher efforts of governments to raise revenues. This channel is stronger for small and medium-size enterprises.}

_{Changes in the sentiment of migration-related news published in destination countries affect the timing of migrants¡¯ journeys to these countries. Using geo-localized data on migrants in Libya and the complete record of news articles in their country of destination, this paper shows that a worsening news sentiment leads to migrants staying longer in Libya, slowing down their journeys to their final destinations. The paper validates these results by showing that the effect is concentrated in locations with internet connections. The results indicate that changes in news sentiment have a significant impact only for some groups of migrants and under specific conditions, suggesting a limited effect on overall migrant movements. Finally, the paper provides suggestive evidence that a worsening news sentiment in the preferred destination induces substitution across destination countries, yet it does not make migrants return to their country of origin.}

_{The existing literature on development and economic diversification finds an inverted-U function between these two variables, whereby economies diversify as they grow up to a point, after which they start specializing. This paper contributes to this literature by investigating the stages of diversification over the course of development during the past 57 years. The paper emphasizes the trajectories of resource-rich and resource-poor countries, an issue that has not been covered by the extant literature. In addition, the paper studies the stages of diversification across three dimensions, namely employment, value-added, and exports. Additionally, it examines the relationship for services. Non-parametric estimations suggest a U-shaped curve between measures of economic concentration and per capita income levels, which is in line with existing evidence. However, these patterns are mainly driven by between-country rather than within-country variation, a finding that had been ignored in the existing literature. Diversification patterns also differ across resource-rich and resource-poor countries: Employment and value added in resource-rich countries are on average more concentrated at low levels of development while in resource poor countries, they are more concentrated at high levels of development. In contrast, at all levels of development, exports are more concentrated in resource-rich countries.

_{Better managed firms perform better. Existing evidence has shown that family-managed firms have poorer management practices. Several reasons have been proposed. Limiting to family members reduces the talent pool of potential managers. Family management creates disincentives for other talented workers given that the environment is not meritocratic. Family managers themselves may be less motivated given that they may not have to compete for the position. This study scales up the evidence by exploring the relationship between family managers and management practices for about 9,000 medium and large firms across 41 developing and advanced economies. The study contributes to the literature by investigating several internal and external operating factors that attenuate or accentuate the relationship between family management and the quality of management practices. The engagement of governments in terms of corruption and political connections is found to be influential.}

_{This study develops a measure of firm-level credit constraints by leveraging refinements in survey instruments for a widely used database. Using data on more than 65,000 firms across 109 economies, the study uncovers several insights. Around 30 percent of firms in the formal private sector are credit constrained. Firms that are credit-constrained tend to be smaller and negatively correlated with performance. The more developed the economy, the lower the share of credit-constrained firms. One striking finding is that 52 percent of firms do not apply for loans as they have sufficient credit. For some economies, this may be more indicative of poor opportunities for the expansion of firms and thus the lack of demand for credit. The findings suggest that for policies that improve access to credit to be effective, they should go hand in hand with interventions that provide opportunities for firms to expand.}

_{This paper investigates the impact of civil conflicts on international trade. First, it quantifies how much civil conflicts suppress trade and explores the underlying mechanisms within a structural gravity model. Trade openness can lower the risk of civil conflicts because expected gains from international trade could discourage both governments and rebels from igniting conflicts (deterrence mechanism). Alternatively, international trade could act as a substitute for internal trade, lowering the opportunity cost of civil conflicts (insurance mechanism). This paper empirically investigates both mechanisms. Second, the paper investigates the spillovers of civil conflicts on trade for neighboring countries uninvolved in the conflict. Third, it examines if the impact of civil conflicts is contemporaneous or persistent through time. The paper uses data on violent civil conflicts and international and intra-national trade data from 142 countries to estimate a structural gravity trade model for 1989¨C2006. The results show that civil conflicts in a country can reduce its trade with other countries by over 40 percent. Spillovers of neighboring civil conflicts are also highly detrimental. Finally, the impact of civil conflicts is highly persistent through time and increases with the duration of the conflict.}

_{Data transparency about critical economic issues may be key to driving growth and enhancing trust in government in the Middle East and North Africa. Several knowledge products and technical analyses on the region have been greatly constrained by the lack of availability of detailed data, and the relatively outdated nature of many available datasets. The goal of this study is to ascertain the state of data systems in the Middle East and North Africa region. Through analysis of several indicators, with their limitations in mind, the study uses descriptive analyses and uncovers six stylized facts of the region: (i) developing economies in the Middle East and North Africa have poor data ecosystems, largely due to the prevalence of conflict; (ii) developing economies in the Middle East and North Africa as a group have experienced the largest deterioration in data systems over time; (iii) data systems in richer economies in the Middle East and North Africa region underperform relative to their income peers; (iv) Gulf Cooperation Council economies underperform in data openness, especially online access, despite having the resources for online features; (v) the regulatory framework for data (data infrastructure) is poor throughout the region, especially in Gulf Cooperation Council economies; and (vi) the dispersion of source data scores ¨C a measure of availability and timeliness of micro data ¨C in the region suggests that national statistical offices in the region could learn from each other. Furthermore, the study summarizes data availability and timeliness for specific macro, micro, and public health indicators for countries across the region.

_{This paper posits marriage market returns as a contributing factor to stagnant female labor force participation despite increasing female education. The paper examines the marriage market returns of female education by exploiting a very direct measure of returns: bride price, a significant amount of resources transferred by the groom at the time of marriage. The paper also looks at current and future husband's wages as additional sources of returns. It addresses endogeneity and identification issues by exploiting a school reform in Egypt that reduced the number of years required to complete primary education from six to five. The staggered rollout of the reform generates exogenous sources of variation in female schooling both across and within cohorts and administrative units. The analysis implements an instrumental variable estimator with fixed effects at the cohort and at the administrative unit level. The estimated return to a bride's compulsory education is about 100% for bride price, about 14% for husband's wage at the time of marriage, and about 16% for a measure of husband's permanent income. Importantly, these returns to education in the marriage market are much higher than the returns to education that Egyptian women experience in the labor market. Additional empirical evidence suggests that educational assortative mating could be an important mechanism through which the marriage market returns are taking place.}

_{The relationship between paid maternity leave and the share of female workers in registered private firms is analyzed using firm-level survey data for 111 developing and emerging countries. Theoretically, the relationship can be either positive or negative. Higher maternity leave raises the cost of female workers to the employer, discouraging female employment. However, higher maternity leave encourages more females to enter the labor market, implying greater female employment. The results show that the latter effect dominates. That is, a positive, large, and statistically significant relationship is found between maternity leave and female employment. A conservative baseline estimate is that the share of female workers in a firm increases by 2.08 percentage points for each log point increase in the number of days of paid maternity leave. Alternatively, an increase in the number of days of paid maternity leave from its smallest to highest value (0 to 410 days) increases the share of female workers by 12.5 percentage points. The positive relationship between female workers and maternity leave is much larger when maternity leave is fully funded by the government than when paid for by the employer, and in countries where there is a higher share of females in the childbearing age group of 20¨C29 years. These heterogeneities highlight channels that accentuate the relationship, thereby serving as checks against endogeneity concerns with the estimation. The distributional implications of paid maternity leave are also analyzed by estimating its impact on low-skilled versus high-skilled employment. Important policy implications of the findings are discussed}
