  • Post Training Assistance in Skills Development Programs: Applicant Selection and Impact Evaluation
    Last registered on July 29, 2021

    Lack of skill development has been a core policy issue in India over the last decade and ambitious skill training programs have been initialized by the government to skill the youth. However, policy reports and prior studies suggest that these programs have had little impact on the livelihood of the youth. In this context, for both wage and self-employment training programs, this study project proposes to partner with Yuva Parivartan to examine two broad research questions: (i) how does the provision of post-training assistance (access to information and resources) impact the labor market outcomes of trainees? (ii) does the mode of information dissemination (either through general announcements, access to experts either on public forums or private sessions have a differential impact? Pu...

  • Replication Dertwinkel-Kalt and Köster (2020, JEEA)
    Last registered on July 29, 2021

    We replicate Experiment 2 in Dertwinkel-Kalt and Köster, "Salience and Skewness Preferences", Journal of the European Economic Association 18(5), 2020, 2057-2107, using a different subject pool. We implement an additional treatment from Loewenfeld and Zheng (2021) that allows us to control for so-called event-splitting effects.

  • How to communicate uncertainty? The effects of asymmetrical interval predictions on ambiguity attitudes.
    Last registered on July 29, 2021

    We investigate experimentally how a forecaster’s acknowledgement of uncertainty affects the reader’s ambiguity attitudes in a task that is characterized by a high degree of uncertainty. To this end, we expose a representative survey sample to historical temperatures and indirectly ask them to make a forecast using Baillon et al’s (2018) method. Subsequently, we introduce them to a real expert’s temperature forecast and repeat Baillon’s tasks. The weather forecast is manipulated exogenously in a 2x3 between-subject design and differs with respect to the communication strategies: The forecast contains either a point estimator, an asymmetric interval estimator, or both. In addition, we vary the forecasts’ moment of surprise as one set of forecasts (literally) is in line with the historica...

  • Strategic avoidance of lying costs
    Last registered on July 29, 2021

    I study whether people take advantage of privileged positions to have someone lying on their behalf without explicit delegation. I use a sequential cheating game in dyads in which if at least one member of the dyad lie, both benefit from it. Consequently, the first-mover can avoid the cost of lying by reporting truthfully if he or she expects that the second-mover will lie. I use treatment variations to eliminate the belief of the second-mover lying, control for the positive externality of the first-mover lie, and control for simultaneous decisions.

  • Long-Term Double Fortified Salt Usage for Child Health in Rural Bihar
    Last registered on July 29, 2021

    Many existing nutrition interventions evaluate the short-term effects on child health focusing on whether treatment matters for child health. To what degree timing and duration of exposure to a long-term nutrition intervention matter for child development is hardly considered. We want to provide evidence by examining the effectiveness of a hardly implemented government directive in India that postulates all government run schools to improve children’s diets by using iron and iodine fortified salt called double-fortified salt [DFS] in the school feeding program. Facilitating the availability of DFS at 107 randomly selected governmental schools in two blocks of the district Jehanabad in the state of Bihar, India, we want to examine how timing and duration of the use of DFS effect child heal...

  • Experimental Evaluation of the Primeira Infância Melhor Program
    Last registered on July 28, 2021

    This study aims to evaluate the 'Primeira Infância Melhor' Program (Better Early Childhood, PIM), an ongoing large scale home visiting program targeting socioeconomically disadvantaged families to promote the health, cognitive and socioemotional development of young children during their early years of development in the Brazilian State of Rio Grande do Sul. We explore program expansion within municipalities to randomize individuals (either children aged 0-3 or expectant mothers) into the treatment group or a waiting list whenever there is excess demand. We will assess program impacts on child development, parental practices, parent-child relationship and family access to services. This trial also sets up the building blocks of a longitudinal study design to evaluate medium and long-ter...

  • The impact of narratives and conceptual frames on economic and government attitudes: Evidence regarding negative externality
    Last registered on July 28, 2021

    This work involves the online implementation of a survey experiment with random assignment. Each participant is presented with five different vignettes in which firms or consumers generate negative externalities and the government intervenes to address the external costs. Participants are asked to rate the fairness of the externality, the government intervention, and the situation that exists once the intervention is in place. The vignettes, inspired by the work of Kahneman, Knetsch, and Thaler (1986) are designed to test individuals’ responses to the framing and characteristics of the negative externality and the government response to the externality.

  • The Impacts of Short-Run Free Distribution on Subsequent Consumers' Demand for a Commercial Baby Food in Developing Countries
    Last registered on July 28, 2021

    Free distribution of nutritionally fortified complementary food products has been one of the popular approaches for improving infant nutrition in developing countries. In contrast, the market of baby foods is rapidly growing in developing countries nowadays, particularly in Africa. If the prevalence of those products through the market improves infant nutrition, a market-based approach will be a sustainable way to solve infants’ undernutrition. The free distribution can have two opposite effects on the market-based approach. The negative one is known as an anchoring effect. Free distribution discourages mothers from subsequent purchasing in the market after the end of the intervention. It is because being free makes beneficiaries feel that it is expensive to buy a product in the ma...

  • A brief intervention in reducing alcohol consumption in China: study protocol for a cluster randomized controlled trial
    Last registered on July 28, 2021

    Alcohol is the 7th leading risk factor of Disabled Adjusted Life Years (DALYs) all over the world according to the Global Burden of Disease study 2017 .As the largest developing country, Chinese people consume a large amount of alcohol, and suffer from related health risk. The aim of this paper is to provide an overview of alcohol consumption among the ethnic population in China, and to test the feasibility and efficacy of small financial incentives with brief advice intervention targeting the reduction of harmful drinking behaviors among poor people.

  • Understanding and Improving Policymakers' Sensitivity to Program Impact
    Last registered on July 28, 2021

    When making decisions about which programs to implement, policymakers must assess impact in the face of bounded rationality constraints when processing relevant information. These constraints may result in “under-sensitivity” to impact-relevant information about evidence-based programs, ultimately leading to support for less impactful interventions, as compared to a utilitarian benchmark. This study uses a lab-in-the-field experiment among federal employees of the US government to estimate and seek to improve sensitivity. We will first document any under-sensitivities in government decision making across three key program attributes relevant to impact: scope, outcome type, and effect persistence. The primary goal of this study is to test modes of presenting program information that incr...
