Behavioural Development Economics: Lessons from Field Labs in the Developing World

Explanations of poverty, growth and development depend on the assumptions made about individual preferences and the willingness to engage in strategic behaviour. Economic experiments, especially those conducted in the field, have begun to paint a picture of economic agents in developing communities that is at variance with the traditional portrait. We review this growing literature with an eye towards preference-related experiments conducted in the field. We also offer lessons on what development economists might learn from experiments. We conclude by sharing our thoughts on how to conduct experiments in the field and then offer a few ideas for future research.     

COVID-19 Pandemic and Intimate Partner Violence: an Analysis of Help-Seeking Messages in the Spanish-Speaking Media

The role of the Spanish-speaking media is crucial for how Latinx communities learn about seeking help when experiencing intimate partner violence (IPV). This study investigated the IPV help-seeking messages disseminated by the Spanish-speaking media in the U.S. during the COVID-19 pandemic. We engaged in an exploratory content analysis of videos from Univision’s main website, the most-watched Spanish-speaking media network in the U.S. We searched for videos related to IPV help-seeking posted from March 19–April 21, 2020—including the weeks after the World Health Organization declared COVID-19 a global pandemic and the U.S. mandated a shelter-in-place. After assessing inclusion criteria, 29 videos were analyzed. Data were analyzed using basic content analysis to determine frequencies and inductive interpretive content analysis to code for help-seeking messages. We identified eight manifest messages related to seeking help when experiencing IPV in times of a crisis: (1) contact a professional resource; (2) contact law enforcement; (3) contact family, friends, and members of your community; (4) create a safety plan; (5) don’t be afraid, be strong; (6) leave the situation; (7) protect yourself at home; and (8) services are available despite the pandemic. We found that the manifest messages alluded to three latent messages: (1) it is your responsibility to change your circumstances; (2) you are in danger and in need of protection; and (3) you are not alone. IPV and media professionals should ensure a structural understanding of IPV in their help-seeking messages and avoid perpetrating stigmatizing and reductionist messages.

     

The Inclusion of Nonsafety Criteria within the Regulatory Framework of Agricultural Biotechnology: Exploring Factors that Are Likely to Influence Policy Transfer

Policy makers of various countries are exposed to critiques that call for the consideration of issues that transcend human, animal, and environmental safety concerns when assessing agricultural biotechnology products. While some jurisdictions have decided to broaden the scope of their approval process for genetically modified (GM) foods, this paper analyzes legal, political, and economic factors that can influence the transfer of these initiatives. Drawing on mechanisms presented in the policy transfer literature, this article examines their mixed effects pertaining to the regulation of biotechnology. Although the mechanisms of competition and coercion do not preclude such a possibility, one must admit that they do not create any incentives for policy makers to include nonsafety criteria within biotechnology regulations. By contrast, to varying degrees, the mechanisms of mimicry and learning can foster the transfer of such a broadened scope that allows a better assessment of GM foods' social acceptability.     

A Small Population Study on Friction Skin Ridges: Differences in Ridge Widths Between Latent and Inked Fingerprints

Morphological changes in the width of latent fingermark ridges occur naturally over time. This could be used to examine the aging process of latents and eventually estimate time of deposition. In a crime context, it is common practice to compare a questioned (aged) fingermark with a database of known (inked) prints. Therefore, in the absence of fresh fingermarks for aging purposes, it is of interest to reveal correlations between these two categories of fingerprints with regard to the widths of their ridges. The present study explores correlations of ridge widths between flat and rolled inked prints with latent fingermarks visualized with carbon black (CB) and titanium dioxide (TiO₂)-based powders among a small population of ten donors. Results revealed consistent differences between the ridge widths of latent and inked prints as well as flat and rolled impressions. Latent fingermarks visualized with CB and TiO₂ powders showed ridges with comparable widths.
