Fueled by advances in computing technology and the availability of data, quasi-experimental methodologies have become as ubiquitous as they are powerful, applied to answer questions ranging from the effects of economic shocks on civil conflict (Miguel, Sayanath, and Sergenti, 2004), to the effects of the Clean Water Act on water pollution levels (Keiser and Shapiro, 2019), and effects of access to food stamps in childhood on later life outcomes (Hoynes, Schanzenbach, Almond 2016 Bailey et al., 2020). The use of these methods is now widespread, not just in economics, but in other social sciences as well. Pioneering applications of this approach include work by Angrist and Krueger (1991) leveraging variation in compulsory school attendance laws to measure the effects of schooling on earnings and work by Card and Krueger (1994) leveraging minimum wage variation across state borders to measure the effects of the minimum wages on employment outcomes. Faced with this obstacle, economists turn to “natural” or “quasi” experimental methods, ones in which they are able to credibly argue that treatment is as good as randomly assigned. For instance, one cannot feasibly or ethically randomly assign abortion access to some individuals but not others. However, in the social world, this opportunity is often not available. When economists can feasibly and ethically implement such experiments, they do.

The gold standard for establishing such credibility is a well-executed randomized controlled trial – an experiment conducted in the lab or field in which treatment is randomly assigned. This year’s decision by the Economic Sciences Prize Committee recognized the contributions 3 of economists David Card, Joshua Angrist, and Guido Imbens, awarding them the Nobel Prize for their pathbreaking work developing and applying the tools of causal inference in a movement dubbed “the credibility revolution” (Angrist and Pischke, 2010). Powerful statistical methodologies in the causal inference toolbox have made it possible for economists to do just that, moving beyond the maxim “correlation isn’t necessarily causation” and applying the scientific method to figure out when it is. To measure the causal effect of abortion on women’s lives, one must differentiate its effects from those of other forces, such as economic opportunity, social mores, the availability of contraception. Separating Correlation from Causation: The “Credibility Revolution” in Economics The field of economics affords insights into these objective questions through the application of sophisticated methodological approaches that can be used to isolate and measure the causal effects of abortion access on reproductive, social, and economic outcomes for women and their families.
While the debate over abortion often centers on largely intractable subjective questions of ethics and morality, in this instance the Court is being asked to consider an objective question about the causal effects of abortion access on the lives of women and their families. An official announcement concerning the departures is expected to be made December 1st.Senior Research Assistant & Project Coordinator - Center on Children and Families, Economic Studies, Brookings Institution Yahoo! Japan notes that Suzuki has told officials in other organizations that she is wrapping up with Ice Ribbon. Onita told the press he’ll consider taking the winner with him to the United States and he’ll recommend that individual to a promoter he knows in the States. Suzuki is going to be competing against Akane Fujita in an explosion match. She has also been competing for Atsushi Onita’s FMW-E promotion and is scheduled for the December 19th show. The 19-year-old Suzu Suzuki challenged for the ICExInfinity Championship on 11/28. They first captured the titles in August at Ice Ribbon’s 15th Anniversary show. Yukihi and Sera are the reigning International Ribbon Tag Team Champions.
The site adds that others are expected to depart as well. Yahoo! Japan is reporting that Suzu Suzuki, Risa Sera and Maya Yukihi are all leaving Ice Ribbon. The Ice Ribbon promotion in Japan will reportedly be losing multiple talents at the end of the year.
Three talents leaving Ice Ribbon at the end of the year, per report.
