Limited government capacity and insufficient collaboration/partnership to garner government buy-in were the main reasons behind the lack of success for several ESW in the Democratic Republic of Congo. In contrast, a few ESW in this country had very positive effects because of substantial partnering and collaboration.
Even in countries with high levels of capacity, purely supply-driven tasks without government buy-in were not effective. An example is economic monitoring ESW in MICs that had access to such analysis from the private sector or international investors. The Bank's economic monitoring ESW had very little value added in such circumstances.
Lack of government receptivity because of political constraints could also affect or delay the usefulness of ESW. In Peru, the Sierra Rural Development Strategy became influential only four years after its completion, after a change in government.
Poor quality and slow translation were other reasons behind the poor effects of some ESW in some Latin American and francophone West African countries. In one of the countries, the translation took so long that when the documents finally became available in the local language, they had lost much of their importance for policy making.
