Trust to Pay? Tax Morale and Trust in Africa

(Taylor and Francis, 2021-02-14) Kouamé, Wilfried A.K.

Although low tax morale hits developing countries hardest, little is known about its determinants in those countries. This paper examines the impact of trust in public institutions and the neighbourhood on individual tax morale in four African countries. First, the paper provides theoretical foundations of such a relationship. Further, the paper uses the World Value Survey to estimate the effects of trust in public institutions and the neighbourhood on individual tax morale. The identification strategy employs the instrumental variables method and relies on historical data on the slave trade and the literature on the cultural heritage of trust. The paper finds that trust in public institutions and the neighbourhood are associated with tax morale in Algeria, Ghana, Morocco, and Nigeria. The findings are robust to an alternative identification strategy, additional controls, and a falsification test.
Economic Growth, Convergence, and World Food Demand and Supply

(Elsevier, 2020-08) Fukase, Emiko ; Martin, Will

In recent years, developing countries have been growing much more rapidly than the industrial countries. This growth convergence has potentially very important implications for world food demand and for world agriculture because of the increase in demand for agricultural resources as diets shift away from starchy staples and towards animal-based products and fruits and vegetables. Using a resource-based measure of food production and consumption that accounts for the much higher production costs associated with animal-based foods, this article finds per capita demand growth to be a more important driver of food demand than population growth between now and 2050. Using the middle-ground Shared Socioeconomic Pathway scenario to 2050 from the International Institute for Applied Systems Analysis, which assumes continued income convergence, the article finds that the increase in food demand (102 percent) would be about a third greater than under a hypothetical scenario of all countries growing at the same rate (78 percent). As convergence increases the growth of food supply by less than demand, it appears to be a driver of upward pressure on world food prices.
Six Sigma to Reduce Claims Processing Errors in a Healthcare Payer Firm

(Taylor and Francis, 2020-06) Sunder M, Vijaya ; Kunnath, Nidhin R.

As a continuous improvement practice, Six Sigma has been accepted globally across the service industry. In the past one decade, the application and success of Six Sigma in healthcare services has been remarkable. Despite the fact that several papers on Six Sigma have appeared in the erstwhile literature related to healthcare operations, there is a dearth of field studies highlighting the application of Six Sigma in healthcare outsourced firms, in specific to healthcare payers that engage in a non-clinical setup. The aim of this paper is to explore the role of Six Sigma within the healthcare payer outsourced firms, where error-free delivery becomes critical. The article contributes to the literature of Six Sigma in healthcare outsourcing highlighting how “Six Sigma as a methodology” could help reduce claims adjudication errors in a healthcare payer firm. The Six Sigma DMAIC project case study presented as part of the paper delivered a saving of USD 0.53 million and is a classic example of how Six Sigma can bring bottom-line impact to healthcare outsourced organizations. Managerial implications and lessons learned are discussed alongside the concluding notes.
The Effects of Pollution and Business Environment on Firm Productivity in Africa

(Sage Publications, 2020) Soppelsa, Maria E. ; Lozano-Gracia, Nancy ; Xu, L. Colin

In this paper, we explore the links between city competitiveness and air pollution and business environment. Because competitive cities not only attract more productive firms but also facilitate their business, we choose to look at firm performance as a proxy for city competitiveness. We particularly focus on African firms because this region is developing fast, experiencing increasing pollution levels and the effects of agglomeration economies. We find two interesting results. First, the negative association between air pollution and firm performance can be seen at lower than expected levels of pollution. Second, the effects of capacity agglomeration on labor productivity growth are stronger compared to other regions. These findings suggest that cities in this region should address pollution issues soon, as they continue to grow fast and pollution levels becoming an increasing concern.
Estimating the Welfare Costs of Reforming the Iraq Public Distribution System: A Mixed Demand Approach

(Taylor and Francis, 2019-12-06) Krishnan, Nandini ; Olivieri, Sergio ; Ramadan, Racha

Through three decades of conflict, food rations delivered through the public distribution system (PDS) have remained the largest safety net among Iraq’s population. Reforming the PDS continues to be politically challenging, notwithstanding the system’s import dependence, economic distortions, and unsustainable fiscal burden. The oil price decline of mid-2014 and recent efforts to rebuild and recover have put PDS reform back on the agenda. The government needs to find an effective way to deliver broad benefits from a narrow economic base reliant on oil. The study described here adopts a mixed demand approach to analyzing household consumption patterns for the purpose of assessing plausible reform scenarios and estimating the direction and scale of the associated welfare costs and transfers. It finds that household consumption of PDS items is relatively inelastic to changes in price, particularly among the poor. The results suggest that any one-shot reform will have sizeable adverse welfare impacts and will need to be preceded by a well-targeted compensation mechanism. To keep welfare constant, subsidy removal in urban areas, for example, would require the poorest and richest households to be compensated for, respectively, 74 per cent and nearly 40 per cent of their PDS expenditures.
Fresh Money for Health? The (False?) Promise of 'Innovative Financing' for Health in Malawi

(Taylor and Francis, 2018-10-29) Chansa, Collins ; Mwase, Takondwa ; Matsebula, Thulani Clement ; Kandoole, Priscilla ; Revill, Paul ; Makumba, John Bosco ; Lindenow, Magnus

Since 2013, the government of Malawi has been pursuing a number of health reforms, which include plans to increase domestic financing for health through “innovative financing.” As part of these reforms, Malawi has sought to raise additional tax revenue through existing and new sources with a view to earmarking the revenue generated to the health sector. In this article, a systematic approach to assessing feasibility and quantifying the amount of revenue that could be generated from potential sources is devised and applied. Specifically, the study applies the Delphi forecasting method to generate a qualitative assessment of the potential for raising additional tax revenues from existing and new sources, and the gross domestic product (GDP)-based effective tax rate forecasting method to quantify the amount of tax revenue that would be generated. The results show that an annual average of 0.30 USD, 0.46 USD, and 0.63 USD per capita could be generated from taxes on fuel and motor vehicle insurance over the period 2016/2017–2021/2022 under the low, medium, and high scenarios, respectively. However, the proposed tax reform has not been officially adopted despite wide consultations and generation of empirical evidence on the revenue potential. The study concludes is that revenue generation potential of innovative financing for health mechanisms in Malawi is limited, and calls for efforts to expand fiscal space for health to focus on efficiency-enhancing measures, including strengthening of governance and public financial management.
The Long-term Impacts of International Migration: Evidence from a Lottery

(Published by Oxford University Press on behalf of the World Bank, 2018-02-01) Gibson, John ; McKenzie, David ; Rohorua, Halahingano ; Stillman, Steven

We examine the long-term impacts of international migration by comparing immigrants who had successful ballot entries in a migration lottery program, and first moved almost a decade ago, with people who had unsuccessful entries into those same ballots. The long-term gain in income is found to be similar in magnitude to the gain in the first year despite migrants upgrading their education and changing their locations and occupations. This results in large sustained benefits to their immediate family who have substantially higher consumption, durable asset ownership, savings, and dietary diversity. In contrast we find no measurable impact on extended family.
The Health Gains, Financial Risk Protection Benefits, and Distributional Impact of Increased Tobacco Taxes in Armenia

(Taylor and Francis, 2018-01) Postolovska, Iryna ; Lavado, Rouselle ; Tarr, Gillian ; Verguet, Stephane

The majority of Armenian adult males smoke, yet tobacco taxes in Armenia are among the lowest in Europe and Central Asia. Increasing taxes on tobacco is one of the most cost-effective public health interventions, but many opponents often cite regressivity as an argument against tobacco taxation. We use a mixed-methods approach to study the potential regressivity of tobacco taxation and the extent to which the regressivity argument hindered increases in tobacco taxation in Armenia. First, we pursued an extended cost-effectiveness analysis (ECEA) to assess the health, financial, and distributional consequences (by consumption quintile) of increases in the excise tax on cigarettes in Armenia. We simulated a hypothetical price hike leading to a tax rate of about 75% of the retail price of cigarettes, which would be fully passed on to consumers. Second, we conducted a series of stakeholder interviews to examine the importance of the regressivity argument and identify the factors that allowed tobacco tax increases to be adopted as public policy in Armenia. We show that increased excise taxes would bring large health and financial benefits to Armenian households. Half of tobacco-related premature deaths and 27% of associated poverty cases averted would be concentrated among the bottom 40% of the population. Though regressivity was raised as a concern at the initial stages of the policy adoption process, our qualitative stakeholder analysis indicates that the recent accession to the Eurasian Economic Union and the fiscal constraints faced by the government created a window of opportunity for tobacco taxation to be placed on the policy agenda and adopted as government policy, and the ECEA findings were an important input into the process.
Particulate Matter and Labor Supply: The Role of Caregiving and Non-linearities

(Elsevier, 2017-11) Aragon, Fernando M. ; Miranda, Juan Jose ; Oliva, Paulina

This paper examines the effect of air pollution on labor supply in Lima, Peru. We focus on fine particulate matter (PM2.5), an important pollutant for health according to the medical literature, and show that moderate levels of pollution reduce hours worked for working adults. Our research design takes advantage of rich household panel data in labor outcomes to address omitted variables. This research design allows us to investigate whether the response to air pollution is non-linear. We find that the effect of moderate pollution levels on hours worked is concentrated among households with susceptible dependents, i.e., small children and elderly adults; while the highest concentrations affect all households. This suggests that caregiving is likely a mechanism linking air pollution to labor supply at moderate levels. We provide further evidence of this mechanism using data on children morbidity. Finally, we find no evidence of intra-household attenuation behavior. For instance, there is no re-allocation of labor across household members, and earnings decrease with air pollution.
No Condition Is Permanent: Middle Class in Nigeria in the Last Decade

(Taylor and Francis, 2017-09-21) Corral Rodas, Paul Andres ; Molini, Vasco ; Oseni, Gbemisola

The economic debate on the existence and definition of the middle class has become particularly lively in many developing countries. Building on a recently developed framework called the Vulnerability Approach to Middle Class (VAMC) to define the middle class, this paper tries to estimate the size of the Nigerian middle class in a rigorous quantitative manner and to gauge its evolution over time. Using the VAMC method, the middle class group can be defined residually from the vulnerability analysis as those for which the probability of falling into poverty is below a certain threshold. The results show that there has been considerable improvement in the size of the Nigerian middle class from 13 per cent in 2003/4 to 19 per cent in 2012/13. However, the rate has been slower than expected given the high growth rates experienced in the country over the same period. The results also paint a heterogeneous picture of the middle class in Nigeria with large spatial differences. The southern regions have a higher share and experienced more growth of the middle class compared with the northern regions.
