The delivery of child care and elder care services have far-reaching implications for our …

Predicting Rail Transit Impacts With Endogenous Worker Choice: Evidence From Oahu, Justin Tyndall

Upjohn Institute Working Papers

The provision of public transportation can improve the accessibility of work opportunities. However, predicting the labor market effects of new transit infrastructure is difficult because of endogenous worker decisions. I examine a large public-transit rail project on the island of Oahu, Hawaii. Using block-level commuter-flow and travel-time estimates, I propose and estimate a quantitative spatial model of location and mode choice for workers. I estimate that the new rail system increases public-transit-mode share and the employment rate but does not reduce the average commute duration, because of endogenous worker sorting. Low-income workers on Oahu capture a significant share of transit’s …

Nevada’S Care Workforce: Obstacles And Opportunities For Policymakers, David Damore, Caitlin J. Saladino, William E. Brown Jr., Fatma Nasoz

Policy Briefs and Reports

The care economy includes “the paid and unpaid labor and services that support caregiving in all its forms.” This work includes caring for children, the elderly, and those who are ill or have disabilities. Care work is often undervalued, underpaid, and without a fair system of work benefits in place (e.g. contracts, paid leave, workers’ rights) that in many cases falls disproportionately on women and communities of color. In this policy brief, we examine the care economy in Nevada by focusing on three areas of care: (1) child care; (2) elder care; and (3) mental and behavioral health care. In …

The Southern Nevada Care Economy: Challenges And Opportunities, Tripp Umbach

Policy Briefs and Reports

National policymakers increasingly recognize the care economy as an essential economic driver, contributing $648 billion annually to the U.S. economy and supporting 3.6 million jobs. The care economy is also critical in driving economic development and prosperity in Southern Nevada. Yet, as this Tripp Umbach analysis finds, Southern Nevada’s care economy dramatically underperforms compared to national benchmarks and peer regions. High caregiving costs and limited access to care for children, seniors, and individuals with disabilities in Southern Nevada strain families, businesses, and public resources. This burden reduces workforce participation, productivity, and economic growth. Low pay and high turnover among care …

Growers’ Perceptions And Strategies To Mitigate Spring Frost Injury In Grapevines, Vinicius Cervilieri, Imed Dami, Guilherme Signorini

Journal of Extension

Uncertain weather patterns raise concerns about frequent spring frosts and injury in grapevines. This article quantifies growers’ perceptions of susceptibility to spring frosts and examines their satisfaction with existing mitigation strategies. Departing from a survey with grape growers, results show that over 80% of sampled growers have experienced damage due to frosts. Over-vine sprinklers, proper site selection, and adoption of late budding cultivars are the practices with the highest satisfaction levels. None of the strategies examined reached the highest satisfaction score. In addition, 61% of respondents showed interest in sprayable products to delay budbreak and circumvent grapevine damage.

The COVID-19 pandemic led to a global crisis that forced governments to implement restrictive measures to control the spread of the disease. Although these restrictions, such as community quarantines, played a pivotal role in stabilizing healthcare systems, they also caused forced closures of various economic sectors that resulted in huge societal costs and severely impacted the marginalized. In order to understand and quantify the economic impact of the COVID-19 pandemic in the Philippines, an integrated modeling approach, which combined an epidemiological compartmental model and an economic model, was utilized. The evolving nature of COVID-19 required continuous updating of the integrated …

A Strategic Topology On Information Structures, Dirk Bergemann, Stephen Morris, Rafael Veiel

Cowles Foundation Discussion Papers

Two information structures are said to be close if, with high probability, there is approximate common knowledge that interim beliefs are close under the two information structures. We define an “almost common knowledge topology” reflecting this notion of closeness. We show that it is the coarsest topology generating continuity of equilibrium outcomes. An information structure is said to be simple if each player has a finite set of types and each type has a distinct first-order belief about payoff states. We show that simple information structures are dense in the almost common knowledge topology and thus it is without loss …

Strengthening Work Requirements? Forecasting Impacts Of Reforming Cash Assistance, Josep M. Nadal-Fernandez, Gabrielle Pepin, Kane Schrader

Upjohn Institute Working Papers

Work requirements are perhaps the most controversial aspect of the Temporary Assistance for Needy Families (TANF) program, America’s sole federal cash assistance program for low-income families with children. In 2025, for the first time in nearly 20 years, the Fiscal Responsibility Act of 2023 (FRA) will implement policy changes intended to strengthen states’ work requirements. However, researcher’ and policymakers’ understanding of how FRA will impact states’ compliance with federal requirements is hampered by a lack of research and publicly available data.

We tie information from reports submitted to the U.S. Department of Health and Human Services that are collected to …

Likert Scale Variables In Personal Finance Research: The Neutral Category Problem, Blain Pearson, Donald Lacombe, Nasima Khatun

Finance and Economics

Personal finance research often utilizes Likert-type items and Likert scales as dependent variables, frequently employing standard probit and ordered probit models. If inappropriately modeled, the "neutral" category of discrete dependent variables can bias estimates of the remaining categories. Through the utilization of hierarchical models, this paper demonstrates a methodology that accounts for the econometric issues of the neutral category. We then analyze the technique through an empirical exercise relevant to personal finance research using data from the National Financial Capability Study. We demonstrate that ignoring the "neutral" category bias can lead to incorrect inferences, hindering the progression of personal finance …

Climate risk is one of the type of risks in a bank’s portfolio which is not fully recognized, and its impact on the future overall risk changes is hidden due to lack of sufficient knowledge at the moment. One of the most common data comes from Network for Greening the Financial System (NGFS) scenarios related to climate change (physical risk) and climate policy and technology trends (transition risk). In the paper we focused on the transition risk scenarios and their impact on the economy and in particular on credit risk. Our main goal was to check the tendency in the …

The Welfare Effects Of Including Household Preferences In School Assignment Systems: Evidence From Ecuador, Gregory Elacqua, Isabel Jacas, Thomas Krussig, Carolina Méndez, Christopher Neilson

Discussion Papers

We partner with Ecuador’s government to implement a centralized school choice system using a Deferred Acceptance algorithm in Manta. Our study evaluates the welfare impact of transitioning from a distance-based assignment system to one that incorporates families’ preferences. Results show that accounting for preferences yields substantial welfare gains. Counterfactual analyses suggest that alternative mechanisms offer limited improvements compared to the benefits of preference inclusion and coordinated assignments. Household survey data on beliefs and satisfaction support these findings, indicating that centralized school choice systems can deliver significant welfare effects in developing countries.
