This is a follow-on from a question on Meta.
Would the question below, possibly with slight adjustments, be suitable for Politics SE?
I am looking for empirical evidence that making direct monetary payments to targeted groups of deprived people - say paying all families living in a certain poor district fifty dollars every month, similar to a guaranteed basic income (see Wikipedia) or what the charity GiveDirectly does - can provide short to medium term political benefits to the government (local, regional, national, other) doing it, as well as under which circumstances the political benefits might be particularly high per dollar spent compared to other forms of subsidies or spending. Political benefits might include increased government popularity, increased political stability, decreased crime rates or decreased ethnic tension. Circumstances might include target group (urban community, rural community) and overall political situation and structure (form of goverment, economic climate, situation of peace or conflict). Dollars are used here as the typical reference currency. Potential sources of empirical evidence might include studies of Brazil's "Bolsa Família" programme.
