|Bulman et al., 2017|Yes (Table<br>A1.2 and<br>Text)|What is the relative importance of country vs. project<br>characteristics in driving aid effectiveness at the WBG and<br>ADB?|Country-level characteristics explain only 10-25% of project success, indicating an<br>important role for project-specific factors in understanding project outcomes. Shorter<br>project duration, the presence of additional financing and the track record of the project<br>manager in delivering successful projects are highly significantly correlated with project<br>outcomes. Findings do not significantlydiffer between the two institutions.|

|Buntaine and Parks,<br>2013|Yes (Table<br>A1.2 and<br>Text)|Does the influence of previously identified potential predictors<br>of successful outcomes in environmentally focused assistance<br>projects carry over to environmentally focused World Bank<br>projects’ outcome ratings?|<br>Three predictor variables had a robust relationship with outcome ratings: the<br>government effectiveness index and the IEG rating for quality of supervision showed a<br>strong and positive relationship; a project focus on preventing climate change or<br>protecting biodiversity (“global outcomes”) had a negative relationship|
|Caselli and Presbitero,<br>2021|<br>Yes (Table<br>A1.2 and<br>Text)|How predictable and effective are aid inflows to fragile states?|<br>Using a large data set of aid projects funded by seven large donors over 190-2012, the<br>authors find that a project implemented in a fragile state is about 8 percentage points<br>less likely to be successful than a similar project financed in another developing country.|
|Chauvet et al., 2010|Yes (Table<br>A1.2 and<br>Text)|What is the probability that World Bank projects will be<br>successful depending on a set of projects and country<br>characteristics, including detailed factors relating to the<br>history of civil war in countries?|The probability that World Bank projects will be successful depending on a set of projects<br>and country characteristics, and factors relating to the history of civil war in countries.|
|Chauvet et al., 2013|Yes (Table<br>A1.2 and<br>Text)|Is the impact of supervision on project success related to the<br>degree of divergence of interests between the donor and the<br>recipient country?|Supervision is differentially effective in improving the performance of projects where<br>donor and recipient country interests are least congruent. However, donors do not<br>accordingly expend greater effort in supervision in situations of widely divergent<br>interests, suggesting that either there are offsetting costs of supervision, or incentives<br>facing donor management to allocate administrative budgets are not well-aligned with<br>the objective ofproject success.|
|Clark and Dolan, 2021|<sup>Yes (Text</sup><br>only)|How do policies in international organizations reflect the<br>preferences of powerful institutional stakeholders? Examining<br>evidence of US influence in WB policy loans.|<br>Using a data set on the conditions associated with World Bank policy loans, the authors<br>find that borrower countries that vote with the United States at the United Nations are<br>required to enact fewer domestic policy reforms, and on fewer and softer issue areas<br>(prior action data set for DPLs).|
|Corral and McCarthy,<br>2020|Yes (Table<br>A1.2 and<br>Text)|Do quality-at-entry assessments enhance the delivery of<br>development projects at the IDB?|In the IDB, quality-at-entry project assessment - especially higher scores on project logic<br>and economic analysis - is correlated with implementation performance. However,<br>monitoring and impact assessment scores had limited impacts on performance.|
|Deininger et al., 1998|Yes (Table<br>A1.2 and<br>Text)|Does economic and sector work (ESW) improve the quality of<br>World Bank loans? How do managers decide on staff time<br>allocation trade-offs?|The article sets out an idealized model of decision-making in which a country manager<br>makes an allocation of resources between lending services and economic and sector<br>work. ESW has a significant positive impact on the quality of World Bank loans, but<br>country managers choose to allocate resources in favor of preparation at the expense of<br>ESW due to disbursement concerns.|
|Denizer et al., 2013|Yes (Table<br>A1.2 and<br>Text)|To investigate the relative importance of country-level<br>“macro” factors and project-level “micro” factors in driving<br>project-level outcomes.|Country level “macro” measures of the quality of policies and institutions are strongly<br>correlated with project outcome, however, the success of individual development<br>projects varies much more within countries than it does between (80-20). Project size,<br>project length, the effort devoted to project preparation and supervision, and early-<br>warning indicators that flag problematic projects during the implementation stage,<br>accounts for some of this within-country variation. Measures of World Bank project<br>manager quality also matter significantly for the ultimate project outcomes. Excessive<br>TTL turnover worsensproject outcomes.|
