    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

    Parallel Title: Erscheint auch als Bertoli, Simone Migration, Families, and Counterfactual Families
    Keywords: Counterfactual Reasoning ; Family Formation ; Human Rights ; International Economics and Trade ; International Migration ; Law and Development ; Macroeconomics and Economic Growth ; Migrant Policy ; Migrants Families ; Migration ; Remittances ; Status Quo Bias
    Abstract: Migration changes how families form and dissolve, and how one should conceptualize the family. This has implications for thinking about how the migration decision is modelled when individuals are unable to picture the counterfactual families they may have. Differences in marital status can induce two otherwise identical individuals to make different migration decisions. It also has implications for attempts to causally estimate impacts of migration, when the family composition changes with the migration decision itself. This paper shows empirically that changing marital status after migration is widespread, and that the traditional model of a fixed family sending off a migrant who remains part of that same family only describes a minority of migrants moving from developing countries to the U.S. The authors draw out lessons from thinking about counterfactual families for empirical research and for migration policy

    Parallel Title: Erscheint auch als Ana P., Cusolito Capacity Building as a Route to Export Market Expansion: A Six-Country Experiment in the Western Balkans
    Keywords: Broadcast and Media ; Consulting ; Customer Acquisition ; Digital Presence ; Export Competitiveness ; Export Market Expansion ; Information and Communication Technologies ; International Economics and Trade ; Marketing Training ; Private Sector Development ; Skills Development and Labor Force Training ; Small and Medium Enterprises (SME) ; Small and Medium Size Enterprises ; Training
    Abstract: The limited market size of many small emerging economies is a key constraint to the growth of innovative small and medium enterprises. Exporting offers a potential solution, but firms may struggle to locate and appeal to foreign buyers. A six-country randomized experiment was conducted with 225 firms in the Western Balkans to test the effectiveness of 30 hours of live group-based training and 5 hours of one-on-one remote consulting in overcoming these constraints. Treated firms used techniques such as search engine optimization and improved Facebook content to increase their digital presence and better reach foreign customers. A year later, positive and significant impacts are found on the number of customers, and a significant intensive margin increase in export sales. Qualitative interviews suggest this improvement came from a combination of sector-specific advice on market expansion, and through an encouragement effect which gave entrepreneurs the confidence to try new sales strategies

    Parallel Title: Erscheint auch als McKenzie, David Fears and Tears: Should More People be Moving within and from Developing Countries, and what Stops this Movement?
    Keywords: Attachment To Home ; Benefits of Urbanization ; Communities and Human Settlements ; Constraints That Limit Movement ; Economics of Migration ; Health, Nutrition and Population ; Human Migrations and Resettlements ; Internal Relocation ; International Economics and Trade ; International Migration ; Mental Health ; Migration Policy ; Psychological Uncertainty of Relocation ; Wealth and Wellbeing
    Abstract: Only one in seven of the world's population has ever migrated, despite the enormous gains in income possible through international and internal movement. This paper examines the evidence for different explanations given in the economics literature for this lack of movement and their implications for policy. Incorrect information about the gains to migrating, liquidity constraints that prevent poor people paying the costs of moving, and high costs of movement arising from both physical transportation costs and policy barriers all inhibit movement and offer scope for policy efforts to inform, provide credit, and lower moving costs. However, the economics literature has paid less attention to the fears people have when faced with the uncertainty of moving to a new place, and to the reasons behind the tears they shed when moving. While these tears reveal the attachment people have to particular places, this attachment is not fixed, but itself changes with migration experiences. Psychological factors such as a bias toward the status quo and the inability to picture what one is giving up by not migrating can result in people not moving, even when they would benefit from movement and are not constrained by finances or policy barriers from doing so. This suggests new avenues for policy interventions that can help individuals better visualize the opportunity costs of not moving, alleviate their uncertainties, and help shift their default behavior from not migrating

    Parallel Title: Erscheint auch als Print Version: Batista, Catia Testing Classic Theories of Migration in the Lab
    Keywords: Destination Choice ; Employment and Unemployment ; International Economics and Trade ; International Migration ; Lab Experiment ; Migrant Selection ; Poverty Reduction ; Social Protections and Labor ; Wages, Compensation and Benefits
    Abstract: The predictions of different classic migration theories are tested by using incentivized laboratory experiments to investigate how potential migrants decide between working in different destinations. First, the authors test theories of income maximization, migrant skill-selection, and multi-destination choice as they vary migration costs, liquidity constraints, risk, social benefits, and incomplete information. The standard income maximization model of migration with selection on observed and unobserved skills leads to a much higher migration rate and more negative skill-selection than is obtained when migration decisions take place under more realistic assumptions. Second, these lab experiments are used to investigate whether the independence of irrelevant alternatives assumption holds. The results show that it holds for most people when decisions just involve wages, costs, and liquidity constraints. However, once the risk of unemployment and incomplete information is added, independence of irrelevant alternatives no longer holds for about 20 percent of the sample
