In Latin America, Colombia stands out for its more significant and persistent rural–urban educational performance gaps. This paper studies the evolution of this under-performance of Colombian rural areas by conducting a long-term descriptive analysis of a new dataset. The results suggest that the role of the national government is a source of these educational inequalities because rural education was introduced late and deficiently. That is, the national government delayed the provision of education to rural areas. Moreover, even when implemented, these rural educational initiatives proved deficient due to their lack of funds, lower quality, curricula detached from the rural context and a design that amplified regional disparities, thus producing and maintaining significant and persistent rural–urban gaps in education.

In this paper, we investigate devolution in the Northern Irish context. The role of institutional geography is highlighted. Both contemporary and historical (c. 1921–1972) devolution models are discussed. It is argued that institutional factors provide explanations for economic weaknesses found under both devolution models. The evidence presented suggests that the institutional geography has both changed and exhibited continuities and we discuss these features in relation to contemporary issues. In particular, it is argued that institutional geography considerations have shaped the creation of the current review of tax devolution as well as the creation of an independent fiscal council.

Prevention of juvenile sex trading in the US has risen to prominence in public policy discourse. We develop a generalized benefit-cost model to shed light on this policy issue and illustrate the framework with a case study from Minnesota. The model treats government-funded intervention as an investment project and calculates its net present value. Benefits are derived from harms avoided by reducing the extent of sex trading. The impacts of youth involvement in the market for sexual services are highly complex, and clear data on them are lacking. To account for empirical ambiguity we develop the model around a representative individual, approximate the effect of intervention on the sex market, and conduct sensitivity analysis with key model parameters. The case study evaluates seventeen distinct harms caused by sex trading based on conservative best estimates from scholarly literature. We find a large positive Net Present Value, suggesting it is in the best interest of Minnesota taxpayers to support intervention.
