Using information from singletons in fixed-effects estimation: xtfesing
No full textIn this article, we describe the xtfesing command. The command implements a generalized method of moments estimator that allows exploiting singleton information in fixed-effects panel-data regression as in Bruno, Magazzini, and Stampini (2020, Economics Letters 186: Article 108519)
Exploiting information from singletons in panel data analysis: A GMM approach
No full textWe propose a novel procedure, built within a Generalized Method of Moments framework, which exploits unpaired observations (singletons) to increase the efficiency of longitudinal fixed effect estimates. The approach allows increasing estimation efficiency, while properly tackling the bias due to unobserved time-invariant characteristics. We assess its properties by means of Monte Carlo simulations, and apply it to a traditional Total Factor Productivity regression, showing efficiency gains of approximately 8-9 percent

No full textDoes Human Capital Protect Workers against Exogenous Shocks? South Africa in the 2008-2009 Crisis
No full textThe financial and economic crisis of 2008 and 2009 has taken its toll on the South African economy. The economy contracted for the first time since 1998, and entered recession during the fourth quarter of 2008. The GDP contraction was soon transmitted to the labor market. Between the second quarters of 2008 and 2009, employment fell by 3.8 percent. However, not all individuals were hit with the same intensity. Using labor force survey data unique in the African context, we find that human capital provided a buffer against the shock. After controlling for observable characteristics, education and experience showed the potential to entirely offset the effect of the recession on the likelihood of employment. This has important policy implications, as it strengthens the case for strategic investments in human capital, and helps identifying the unskilled as those with the highest need for social safety net interventions during the recession.labor markets, South Africa, financial crisis, human capital, business cycle, emerging economies
How Large Is the Private Sector in Africa? Evidence from National Accounts and Labor Markets
No full textIn recent years, the private sector has been recognized as a key engine of Africa's economic development. Yet, the most simple and fundamental question remains unanswered: how large is the African private sector? We present novel estimates of the size of the private sector in 50 African countries derived from the analysis of national accounts and labor market data. Our results point to a relatively large size of the African private sector. National account data shows that this accounts for about 2/3 of total investments, 4/5 of total consumption and 3/4 of total credit. In relative terms, large private sector countries are concentrated in Western Africa (Cote d'Ivoire, Guinea, Niger, Senegal and Togo), Central Africa (Cameroun, Republic of Congo) and Eastern Africa (Kenya, Sudan, Uganda and Tanzania), with the addition of Mauritius. Countries with small private sectors include a sample of oil-exporters (Algeria, Angola, Equatorial Guinea, Libya and Nigeria), some of the poorest countries in the continent (Burundi, Burkina Faso, Guinea Bissau, Mali and Sao Tome e Principe), Zambia and Botswana. Over the last ten years, the size of the private sector has been contracting significantly in oil exporting countries, although the variation in its size does not appear to be significantly correlated with growth performance. Labor market data reinforces the idea of a large private sector, which provides about 90% of total employment opportunities. However, most of this labor is informal and characterized by low productivity: permanent wage jobs in the private sector account on average for only 10% of total employment (a share similar to that provided by public administration and state owned enterprises). South Africa is the notable exception, with formal wage employment in the private sector representing 46% of total employment. Finally, we find evidence of negative private sector earning premiums, suggesting that market distortions abound. These are likely to prevent the efficient allocation of human resources, and to reduce the overall productivity of the African economies.private sector size, private sector development, private consumption, private investment, national accounts, private sector employment, private sector earnings, labor markets, Africa

How Did the Great Recession Affect Different Types of Workers? Evidence from 17 Middle-Income Countries
No full textThis paper examines how different types of workers in 17 middle-income countries were affected by labor market retrenchment during the great recession. Impacts on different types of workers varied by country and were only weakly related to the severity of the shock. Among active workers, youth experienced by far the largest adverse impacts on employment, unemployment, and wage employment, particularly relative to older adults. The percentage employment reductions, for example, were greatest for youth in each sector of the economy, as firms reacted to the shock by substituting away from inexperienced workers. Employment rates, as a share of the population, also plummeted for men. Larger drops in male employment were primarily attributable to men's higher initial rate of employment, although men's concentration in the hard-hit industrial sector also played an important role. Within each sector, percentage employment declines were similar for men and women. Added worker effects among women were mild, even among less-educated workers. Differences in labor market outcomes across education groups and urban or rural residence tended to be smaller. These findings bolster the case for targeted support to displaced youth and wage employees. Programs targeted to female and unskilled workers should be undertaken with appropriate caution or empirical support from timely data, as they may not benefit the majority of affected workers.labor markets, emerging economies, economic shocks
Working Paper 110 - Education and Employment in Malawi
No full textThis paper analyzes the relationship betweeneducation and employment in Malawi, usingdata from the 2004-05 Integrated HouseholdSurvey (IHS-2). For both men and women,education is the passport to formalemployment and leads to higher hourlyearnings. Within regular wage employment,secondary education is associated with a123 percent wage premium, and universityeducation with a 234 percent wage premium(relative to illiteracy). In both rural and urbanareas, income is positively correlated withspecialization in regular wage employment.For example, in urban areas 60 percent of thehouseholds who derive at least 75 percent oftheir income from regular wage employmentbelong to the highest quartile of the incomedistribution. This reflects the relative scarcityof human capital. Among prime age males(25 to 39 years old), only 10 percent havecompleted secondary education. For womenin the same age group, the situation is evenworse, with the rate of completion ofsecondary schooling as low as 3 percent.The analysis of school enrolment highlightsthat teenage women experience high dropoutrates, which prevent greater femaleenrollment in higher education, and thereforeconstrain future participation in the bestforms of employment.
