Striking the proper balance between allocating resources into service delivery for low income which benefits society, and moonlighting elsewhere for additional income, is a challenge. A model is developed for how this balance is struck. When the moonlighting production function is concave, common with good governmental monitoring, an internal equilibrium exists. Otherwise either service delivery or moonlighting arises. The model is applied to teachers and healthcare workers within education and healthcare. Survey data from Kenya, Uganda, Tanzania and Senegal show classroom absence for teachers at 29-52.5 per cent, and facility absence for healthcare workers 20-46 per cent. The model is calibrated against the empirics to assess and quantify the factors driving such results. The factors are the shape of the moonlighting production function which governs alternatives to service delivery, the unit cost of service delivery relative to moonlighting for teachers and healthcare workers, and the salaries for service delivery.
219for moonlighting. This shape is mainly controlled by the employer where service delivery is provided, the government through enforcement, the labour market, the legal system, the moonlighting market, and culture. The shape may also be controlled by the actor's ability to navigate the moonlighting market, and the moonlighting employer if such an employer exists. The shape is more likely to be concave if the employer or government vigorously controls and prosecutes moonlighting which interferes with service delivery, and may otherwise be convex. The model is used to test the extent of moonlighting hypothesized to depend on the availability and relative profitability of moonlighting.Although the model is developed for service delivery in general, it is tested empirically applying data from education and healthcare in Kenya, Uganda, Tanzania and Senegal, provided by the World Bank, African Economic Research Consortium and African Development Bank (2018). Across the four countries we consider 239 þ 319 þ 400 þ 151 ¼ 1,109 primary public schools, 67 þ 81 ¼ 148 primary private schools, 2,960 þ 3,783 þ 3,692 þ 248 ¼ 10,683 teachers, 294 þ 389 þ 6,480 þ 151 ¼ 7,314 health facilities, and 1,859 þ 2,357 þ 2,093 þ 153 ¼ 6,462 healthcare workers. For education we consider school absence, classroom absence, time spent teaching, and salary payments delays. For healthcare we consider caseload, facility absence, time spent with patients, and salary payments delays.Many countries decentralize service delivery to the province, council, district, and/or municipal levels. One common purpose is to attempt to improve local accountability; for example, so that the level at which taxes are collected is also the level at which services are delivered. A second purpose of decentralization is to enable the local government to plan, manage, and finance service delivery to their various constituencies. This applies for education and healthcare, more generally for public goods, and in various degrees for law and order, security,...
