|Kilby, 2013|Yes (Text<br>only)|To attempt to isolate post approval informal influence by<br>examining WB disbursements after controlling for prior<br>commitments|The author finds small but positive and significant links between UN voting and WB<br>disbursements of already approved loans, reflecting US informal influence.|

|Kilby, 2015|Yes (Table<br>A1.2 and<br>Text)|p<br>influence in international financial institutions at different<br>stages in the resource transfer process? How does this explain<br>how donors impact the efficacy of international financial<br>institutions?|<br>Predicted preparation duration has a positive and significant relationship with project<br>outcomes. The effects are conditional on the degree of economic vulnerability and the<br>impact greater in countries experiencing debt problems.|
|Limodio, 2011|Yes (Text<br>only)|What is the causal link between the quality of WB project<br>implementation (from the side of the borrower) and its<br>outcome?|Success of infrastructure projects depends fundamentally on the quality of<br>implementation. Although bad implementation can harm structurally solid projects, good<br>implementation cannot make structurally weak projects successful. Governance and<br>selection of well-designed projects are essential for success.|
|Limodio, 2021|Yes (Table<br>A1.2 and<br>Text)|Whether, and to what extent, World Bank managers (Task<br>Team Leaders at PAD) affect project success, and what<br>determines the assignment of a high-performing manager to a<br>specific country?|<br>World Bank project team leaders’ performance indices and country effects both correlate<br>positively with project outcomes. There is evidence of negative assortative matching,<br>with high-performing managers assigned to low-performing countries.|
|Moll et al., 2015|Yes (Table<br>A1.2 and<br>Text)|Are there design elements and other factors of policy-based<br>loans which are tightly linked with success in achieving the<br>intended development outcomes?|Congruence or “line of sight” between the policy reforms supported and the results<br>framework is critical for success. Task team leader skills in general, and staff affiliated<br>with the former “Economic Policy” department of the World Bank also increase the odds<br>of success. A weaker set of reforms and reforms supported in the energy sector tend to<br>reduce the chance of success.|
|Mubila et al., 2000|Yes (Text<br>only)|To assess macroeconomic determinants of project success at<br>the African Development Bank by looking at the relationship<br>between project economic rates of return at appraisal and<br>completion to determine whether they differ more in<br>relatively more challenging environments.|Rates of return at appraisal are weak indicators of future project success. A good policy<br>environment – proxied by rates of economic growth, inflation and a country’s level of<br>development are as important for project success as project characteristics such as size<br>and sector.|
|Presbitero, 2016|Yes (Table<br>A1.2 and<br>Text)|To test for the presence of absorptive capacity constraints in<br>developing countries, and its relationship to aid flows and<br>donor fragmentation|World Bank investment projects are less likely to be successful if implemented during<br>periods of public investment booms, because of absorptive capacity constraints in<br>recipient countries.|
|Shin et al., 2017|Yes (Table<br>A1.2 and<br>Text)|Do different types of implementing partnerships (i.e., state or<br>non-state agencies) affect the outcome of WB development<br>projects?|WB projects implemented by non-state actors are more likely to receive higher<br>effectiveness ratings|
|Smets et al., 2013|Yes (Table<br>A1.2 and<br>Text)|Do World Bank employees exert higher effort in designing<br>programs when faced with governments with left-leaning<br>economic ideologies?|The quality at entry of an economic policy loan is significantly higher for governments<br>with a left-wing party orientation and incumbent tenure is also positively associated with<br>quality at entry, suggesting that WB staff put more effort into their design.|
|Vawda et al., 2003|No|Do World Bank project appraisal documents (PADs) of<br>education projects which are judged “good” have a higher<br>probability of leading to successful project outcomes than<br>projects for which the PADs are judged “poor”?|Outcomes on World Bank education projects are better when the quality of project<br>appraisal is good. There is a strong relationship between the quality of cost-benefit and<br>cost-effectiveness analysis the quality of project outcomes.|
