Policy research and African agriculture: time for a dose of reality? por Omamo, Steven Were, Farrington, John

“…To make policy advice more relevant requires a better understanding not only of how markets (mal)function, but also of implementation issues: what constrains implementability, how constraints can be overcome or bypassed, and what policy measures have greater or lesser prospects of implementation.It concludes that: The policy discourse in African agriculture has been dominated by agricultural economics, yet many of the standard assumptions of quantitative modelling are challenged by the reality of:; markets which are routinely non-competitive because of, eg. high barriers to entry, increasing returns to scale, and non-insurable risk; deliberate efforts by firms to maintain market imperfections by, e.g. building information exchange networks which exclude newcomers; the absence of market pressures towards more competitive structure, conduct or performance The major task of including the poor more fully in markets will continue to be neglected for as long as policy advice remains dominated by unrealistic assumptions; concerning the structure, conduct and performance of markets; This discourse has tended to ignore political priorities such as achieving (or denying) developmental balance among regions or tribes; In addition, the discourse has generally sought some ideal of policy design, disregarding questions of implementability. …”
