Intergenerational Impact of Population Shocks on Children's Health: Evidence from the 1993-2001 Refugee Crisis in Tanzania
(World Bank, Washington, DC, 2019-12)This paper examines how parents' early childhood exposure to a refugee crisis impacts their children's health status. Based on Demographic and Health Survey data from Tanzania with the migration history of mothers and fathers, the analysis exploits geographical, time, and cohort variations using shock intensity and distance from refugee camps to instrument treatment. The findings show that children who were born to parents who were living closer to refugee camps during their early childhood have lower height for their age and are more likely to be stunted. The results are robust to alternative functional forms of the distance from camps, alternative specifications of the treatment and control groups, alternative cohorts of mothers, and several placebo tests. -

The Quest for Subsidy Reforms in Libya
(World Bank Group, Washington, DC, 2015-03)Shortly before the 2011 Libyan revolution, consumers' subsidies were rapidly increased by the regime in an effort to reduce social discontent. In the aftermath of the revolution, these subsidies became important for people's subsistence, but also a very heavy burden for the state budget. Since then, the Libyan government has been confronted with the necessity of reforming subsidies in a politically and socially complex environment. This paper uses household survey data to provide a distributional analysis of food and energy subsidies and simulate the impact of subsidy reforms on household wellbeing, poverty, and the government's budget. Despite the focus on direct effects only, the results indicate that subsidy reforms would have a major impact on household welfare and government revenues. The elimination of food subsidies would reduce household expenditure by about 10 percent and double the poverty rate while saving the equivalent of about 2 percent of the government budget. The elimination of energy subsidies would have a similar effect on household welfare, but a larger effect on poverty while government savings would be almost 4 percent of the budget. The size of these effects, the weakness of market institutions, and the current political instability make subsidy reforms extremely complex in Libya. It is also clear that subsidy reforms will call for some form of compensation for the poor, a gradual rather than a big bang approach, and a product-by-product sequence of reforms rather than an all-inclusive reform. -

An Evaluation of the 2014 Subsidy Reforms in Morocco and a Simulation of Further Reforms
(World Bank Group, Washington, DC, 2015-03)Under increasing budget pressure, Morocco carried out an extensive set of subsidy reforms in 2014 and is planning for further reforms for 2015–2017, which will eliminate most consumers' subsidies. This paper evaluates (ex post) the 2014 reforms and simulates (ex ante) the impact on household welfare, poverty, and the government budget of the total elimination of subsidies. The paper considers food and energy subsidies and estimates direct and indirect effects using SUBSIM, a subsidies simulation model designed by the World Bank. It finds that the 2014 reforms have been a good mix of reforms from a distributional, welfare, poverty, and government budget perspectives. They are perhaps the most rational reforms undertaken in the Middle East and North Africa region in recent years. The analysis also finds further reforms costly for the poor and more complex from a political economy perspective, especially for liquefied petroleum gas. -

Labor Mobility, Economic Shocks and Jobless Growth Evidence from Panel Data in Morocco
(Taylor and Francis, 2015-10-23)During the past 20 years, Morocco has implemented a wide range of macroeconomic, social and labor market reforms that have delivered in terms of GDP growth and household welfare. Yet, these positive developments are not reflected by the main labor market indicators, a phenomenon observed elsewhere in developed and developing economies alike and labeled as ‘jobless growth’. For the first time in Morocco, this paper investigates the question of labor mobility using quarterly panel data in an effort to determine whether people have moved to better sectors and jobs. Results point to significant labor mobility between labor statuses with quite distinct features across population groups. All groups experience some form of labor market mobility every quarter and women are as mobile as men. However, the transitions that women experience are very different from the transitions that men experience and women's performance is worse than men's performance in almost all aspects of labor mobility. -

Prices and welfare
(World Bank, Washington, DC, 2016-02)What is the welfare effect of a price change? This simple question is one of the most relevant and controversial questions in microeconomic theory and its different answers can lead to severe heterogeneity in empirical results. This paper returns to this question with the objective of providing a general framework for the use of theoretical contributions in empirical works, with a particular focus on poor people and poor countries. Welfare measures (such as Equivalent Variation or Consumer's Surplus) and computational methods (such as Taylor's approximations or the Vartia method) are compared to test how these choices result in different welfare measurement under different price shock scenarios. As a rule of thumb and irrespective of parameter choices, welfare measures converge to approximately the same result for price changes below 10 percent. Above this threshold, these measures start to diverge significantly. Budget shares play an important role in explaining such divergence, whereas the choice of demand system has a minor role. Under standard utility assumptions, the Laspeyers and Paasche variations are always the outer bounds of welfare estimates and consumer surplus is always the median estimate. The paper also introduces a new simple welfare approximation, clarifies the relation between Taylor's approximations and the income and substitution effects, and provides an example for treating nonlinear pricing. Stata codes for all computations are provided in annex. -

Prices and Welfare: An Introduction to the Measurement of Well-being When Prices Change
(Springer Nature, 2019)What is the welfare effect of a price change? This simple question is one of the most relevant and controversial questions in microeconomic theory and one of the main sources of errors in empirical economics. This book returns to this question with the objective of providing a general framework for the use of theoretical contributions in empirical works. Welfare measures and computational methods are compared to test how these choices result in different welfare measurement under different scenarios of price changes. As a rule of thumb and irrespective of parameter choices, welfare measures converge to approximately the same result for price changes below 10 percent. Above this threshold, these measures start to diverge significantly. Budget shares play an important role in explaining such divergence. Single or multiple price changes influence results visibly, whereas the choice of demand system has a surprisingly minor role. Under standard utility assumptions, the Laspeyres and Paasche variations are always the outer bounds of welfare estimates, and the consumer’s surplus is the median estimate. The book also introduces a new simple welfare approximation, clarifies the relation between Taylor’s approximations and the income and substitution effects and provides an example for treating non-linear pricing. -

A Comparative Analysis of Subsidy Reforms in the Middle East and North Africa Region
(World Bank, Washington, DC, 2016-07)The paper compares the distribution of energy and food subsidies across households and the impact of subsidy reforms on household welfare in the Middle East and North Africa region. The analysis uses a unified model and harmonized household data. The results show that the distribution of subsidies and the welfare effects of subsidy reforms are quite diverse across countries and products. Energy subsidies tend to be pro-rich in terms of absolute amounts, but tend to be more important for the poor in terms of expenditure shares. Instead, food subsidies are larger for the poor in absolute and relative terms. These findings do not apply everywhere, and the scale of these phenomena are different across countries and products. The welfare effect of a 30 percent reduction in subsidies can be important, especially considering the cumulated effect across products, but the cost of compensating the loss in welfare for the poor is generally low compared with the budget benefits of decreasing subsidies. -

Subsidy Reforms in the Middle East and North Africa Region: A Review
(World Bank, Washington, DC, 2016-07)The paper takes stock of eight country studies and a cross-country analysis to review the experience with subsidy reforms in the Middle East and North Africa region between 2010 and 2014. This unprecedented period of subsidy reforms occurred during a period of extraordinary political changes, which makes this particular experience unique. The paper reviews the facts and the different paths to reforms taken by different countries faced with different challenges, and discusses the pros and cons of alternative policy options. It concludes with an assessment of the experiences and a discussion on future prospects. -

Optimal Targeting Under Budget Constraints in a Humanitarian Context
(Elsevier, 2018-01-05)The paper uses Receiver Operating Characteristic (ROC) curves and related indexes to determine the optimal targeting strategy of a food voucher program for refugees. Estimations focus on the 2014 food voucher administered by the World Food Program to Syrian refugees in Jordan using data collected by the United Nations High Commissioner for Refugees. The paper shows how to use ROC curves to optimize targeting using coverage rates, budgets, or poverty lines as guiding principles to increase the overall efficiency of a program. As humanitarian organizations operate under increasing budget constraints and increasing demands for efficiency, the proposed approach addresses both concerns. -

Risk Preferences and the Decision to Flee Conflict
(World Bank, Washington, DC, 2018-03)Despite the growing numbers of forcibly displaced persons worldwide, many people living under conflict choose not to flee. Individuals face two lotteries -- staying or leaving -- characterized by two distributions of potential outcomes. This paper proposes to model the choice between these two lotteries using quantile maximization as opposed to expected utility theory. The paper posits that risk-averse individuals aim at minimizing losses by choosing the lottery with the best outcome at the lower end of the distribution, whereas risk-tolerant individuals aim at maximizing gains by choosing the lottery with the best outcome at the higher end of the distribution. Using a rich set of household and conflict panel data from Nigeria, the paper finds that risk-tolerant individuals have a significant preference for staying and risk-averse individuals have a significant preference for fleeing, in line with the predictions of the quantile maximization model. These findings are contrary to findings on economic migrants, and call for separate policies toward economic and forced migrants.
