    Parallel Title: Erscheint auch als Iacovone, Leonardo Improving Management with Individual and Group-Based Consulting: Results from a Randomized Experiment in Colombia
    Keywords: Graue Literatur
    Abstract: Differences in management quality are an important contributor to productivity differences across countries. A key question is how to best improve poor management in developing countries. This paper tests two different approaches to improving management in Colombian auto parts firms. The first uses intensive and expensive one-on-one consulting, while the second draws on agricultural extension approaches to provide consulting to small groups of firms at approximately one-third of the cost of the individual approach. Both approaches lead to improvements in management practices of a similar magnitude (8-10 percentage points), so that the new group-based approach dominates on a cost-benefit basis. Moreover, the paper finds some evidence that the group-based intervention led to increases in firm size over the next three years, while the impacts on firm outcomes are smaller and statistically insignificant for the individual consulting. The results point to the potential of group-based approaches as a pathway to scaling up management improvements

    Parallel Title: Erscheint auch als Iacovone, Leonardo Shortening Supply Chains: Experimental Evidence from Fruit and Vegetable Vendors in Bogota
    Keywords: Graue Literatur
    Abstract: Small trading activities are a prevalent form of self-employment in developing countries, but their integration into supply value chains is not efficient, especially when it comes to perishable produce. This study tests a novel approach to improve their efficiency by reducing the time and cost of sourcing produce by aggregating purchases through the use of an app and centralized distribution system. Fruit and vegetable vendors in Bogota currently travel most days to a central market to purchase produce, incurring substantial time and monetary costs. A social enterprise attempted to shorten the supply chain between farmers and vendors by aggregating orders from many small stores, sourcing directly from farmers, and delivering them to the stores. The introduction of this new service was randomized at the market block level. Initial interest was high and offering the service reduced travel time for users by almost two hours a week, reduced travel costs, and increased work-life balance for store owners. Firms offered the service saved an average of 6 to 8 percent on purchase costs, and although some of this passed through into lower prices for consumers, there was incomplete pass-through, so that markups rose. However, stores reduced their sales of products that were not originally offered by this new service, and their total sales and profits appear to have fallen in the short run, with service usage falling over time. The results highlight the potential for new technologies to solve firm coordination problems, offer a window into the nature of competition among small retailers, and point to the challenges in achieving economies of scale when disrupting centralized markets for multi-product firms

    Parallel Title: Erscheint auch als Iacovone, Leonardo Bayesian Impact Evaluation with Informative Priors: An Application to a Colombian Management and Export Improvement Program
    Keywords: Bayesian Impact Evaluation ; Competition Policy ; Competitiveness and Competition Policy ; Economic Theory and Research ; Export Competitiveness ; International Economics and Trade ; Macroeconomics and Economic Growth ; Management ; Prior Elicitation ; Private Sector Development ; Randomized Experiment ; Social Policy Evaluation Method
    Abstract: Policymakers often test expensive new programs on relatively small samples. Formally incorporating informative Bayesian priors into impact evaluation offers the promise to learn more from these experiments. A Colombian government program which aimed to increase exporting was trialed experimentally on 200 firms with this goal in mind. Priors were elicited from academics, policymakers, and firms. Contrary to these priors, frequentist estimation can not reject 0 effects in 2019, and finds some negative impacts in 2020. For binary outcomes like whether firms export, frequentist estimates are relatively precise, and Bayesian credible posterior intervals update to overlap almost completely with standard confidence intervals. For outcomes like increasing export variety, where the priors align with the data, the value of these priors is seen in posterior intervals that are considerably narrower than frequentist confidence intervals. Finally, for noisy outcomes like export value, posterior intervals show almost no updating from the priors, highlighting how uninformative the data are about such outcomes

    Keywords: Adult Remote Learning ; Business Training ; Digital Delivery ; Educational Sciences ; Microenterprises ; Private Sector Development ; Remote Skill Training Effectiveness ; Skills Development and Labor Force Training ; Social Protections and Labor
    Abstract: Standard in-person business training programs are costly and difficult to scale to the millions of microenterprises in the developing world. The authors conducted an experiment to test the feasibility, cost-savings, and impact of delivering live training sessions over Zoom to microentrepreneurs in Mexico and Guatemala. This paper demonstrates that it is now feasible to recruit and train self-employed women online, covering a wide geographic area, with few technology issues. However, the cost savings over in-person classes are less than expected. Training improved business practices and performance over two months, but the impacts had dissipated within six months
