The study simulates a partial registry, containing data from 450 villages across 10 impoverished districts of Malawi, and contains proxy poverty indicators. These indicators are used to impute estimates of household per capita consumption, which in turn are used to train a prediction model using publicly available geospatial data. This method is evaluated against an imputed reference of village welfare, derived from the 2016 household survey. The partial registry approach is benchmarked against three alternatives: proxy means test scores, the Meta Relative Wealth Index, and predictions from household surveys with geospatial indicators. Results show the partial registry model's rank correlation with actual welfare measures at 0.75, outperforming the other methods significantly, which ranged from −0.02 to 0.2. These findings hold under various robustness checks, including the addition of Gaussian noise, indicating that collecting household-level proxy poverty data in low-income areas can significantly improve the performance of machine learning models that integrate survey and satellite imagery data for village-level geographic targeting.","PeriodicalId":361118,"journal":{"name":"The World Bank Economic Review","volume":"51 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141345382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aggregate productivity losses are found to be particularly pronounced in emerging economies where large market frictions impede efficient resource allocation. Available estimates, however, almost entirely exclude firms in the informal sector that in some countries, such as Zimbabwe, make up a high share of overall production and employment. The exclusion of informal firms can result in either an over- or under-estimate of the aggregate productivity losses from misallocation. This paper, therefore, uses firm-level survey data to analyze how market distortions contribute to the misallocation of resources within and between the formal and informal manufacturing sectors in Zimbabwe. Applying the approach developed by Hsieh and Klenow (2009) to firm-level microdata, the results reveal extensive resource misallocation in both the formal and informal manufacturing sector. Market shares of informal firms are found to be low relative to their productivity—an outcome associated with relatively large capital market distortions. Misallocation is also more pronounced among relatively productive firms, thus exacerbating aggregate losses in total factor productivity (TFP). Estimates indicate that aggregated gains in TFP of 151.4 percent can be realized through efficient resource allocation.","PeriodicalId":361118,"journal":{"name":"The World Bank Economic Review","volume":" 1250","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135186421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such data are unavailable in many countries, given limited statistical capacity, shocks that prevent data collection, and regular improvements to survey methodology. This paper demonstrates how jointly deploying backcasting and survey-to-survey imputations can help to overcome this in a setting where estimating a poverty trend is badly needed, given the scale of the poverty-reduction challenge, but where survey-to-survey imputations are more likely to succeed and can be directly tested. In Nigeria, the most recent official survey that can be used to construct an imputation model was collected through the same methodology and in the same year as the target survey. This data landscape could arise in other settings where the methodology for smaller, interstitial surveys is updated more quickly than for larger, official consumption surveys. Naively comparing Nigeria's last two official consumption surveys would suggest that the poverty rate fell by 17 percentage points between 2009 and 2019. Yet the methods presented in this paper both suggest a much smaller reduction in poverty of between 3 and 7 percentage points, echoing Nigeria's performance on nonmonetary welfare indicators over the same period. The paper therefore provides guidance on when and how backcasting and survey-to-survey imputation techniques can be most valuable for monitoring poverty reduction.","PeriodicalId":361118,"journal":{"name":"The World Bank Economic Review","volume":"20 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135455897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
