The emergence of increasingly powerful AI technologies calls for the design and development of K-12 AI literacy curricula that can support students who will be entering a profoundly changed labor market. However, developing, implementing, and scaling AI literacy curricula poses significant challenges. It will be essential to develop a robust, evidence-based AI education research foundation that can inform AI literacy curriculum development. Unlike K-12 science and mathematics education, there is not currently a research foundation for K-12 AI education. In this article we provide a component-based definition of AI literacy, present the need for implementing AI literacy education across all grade bands, and argue for the creation of research programs across four areas of AI education: (1) K-12 AI Learning & Technology; (2) K-12 AI Education Integration into STEM, Language Arts, and Social Science Education; (3) K-12 AI Professional Development for Teachers and Administrators; and (4) K-12 AI Assessment.

Government Old-Age Support and Labor Supply: Evidence from the Old Age Assistance Program
Many government programs transfer resources to older people and implicitly or explicitly tax their labor. We shed new light on the labor supply and welfare effects of such programs by investigating the Old Age Assistance Program (OAA). Exploiting the large differences in OAA programs across states and Census data on the entire US population in 1940, we find that OAA reduced the labor force participation rate among men aged 65–74 by 8.5 percentage points, more than one-half of its 1930–1940 decline, but that OAA’s implicit taxation of earnings imposed only small welfare costs on recipients.

Abstract We develop a multicountry, multisector trade model featuring risk-averse workers, labor market frictions, unemployment benefits, and equilibrium unemployment. Trade opening leads to a reduction in unemployment when it simultaneously raises welfare and reallocates labor toward sectors with lower-than-average labor market frictions. We then estimate and calibrate the model using employment data from 31 OECD countries and worldwide trade data. Finally, we quantify the potential unemployment, real wage, and welfare effects of repealing NAFTA and raising bilateral tariffs between the United States and Mexico to 20%. This policy would increase unemployment by 2.4% in the United States and 48% in Mexico.

Abstract Drug overdose deaths continue to increase in the United States for all major drug categories. Over the past two decades the total number of overdose fatalities has increased more than fivefold; since 2013 the surge in overdose rates is primarily driven by fentanyl and methamphetamines. Different drug categories and factors such as age, gender, and ethnicity are associated with different overdose mortality characteristics that may also change in time. For example, the average age at death from a drug overdose has decreased from 1940 to 1990 while the overall mortality rate has steadily increased. To provide insight into the population-level dynamics of drug overdose mortality, we develop an age-structured model for drug addiction. Using an augmented ensemble Kalman filter (EnKF), we show through a simple example how our model can be combined with synthetic observation data to estimate mortality rate and an age-distribution parameter. Finally, we use an EnKF to combine our model with observation data on overdose fatalities in the United States from 1999 to 2020 to forecast the evolution of overdose trends and estimate model parameters.more » « less

Consumption Insurance against Wage Risk: Family Labor Supply and Optimal Progressive Income Taxationnull (Ed.)We show that a calibrated life cycle two-earner household model with endogenous labor supply can rationalize the extent of consumption insurance against shocks to male and female wages, as estimated empirically by Blundell, Pistaferri, and Saporta-Eksten (2016) in US data. In the model, 35 percent of male and 18 percent of female permanent wage shocks pass through to consumption, compared to the empirical estimates of 32 percent and 19 percent. Most of the consumption insurance against permanent male wage shocks is provided through the presence and labor supply response of the female earner. Abstracting from this private intrahousehold income insurance mechanism strongly biases upward the welfare losses from idiosyncratic wage risk as well as the desired extent of public insurance through progressive income taxation. Relative to the standard one-earner life cycle model, the optimal degree of tax progressivity is significantly lower and the welfare gains from implementing the optimal system are cut roughly in half.

Abstract The direct impacts of climate change on crop yields and human health are individually well-studied, but the interaction between the two have received little attention. Here we analyze the consequences of global warming for agricultural workers and the crops they cultivate using a global economic model (GTAP) with explicit treatment of the physiological impacts of heat stress on humans’ ability to work. Based on two metrics of heat stress and two labor functions, combined with a meta-analysis of crop yields, we provide an analysis of climate, impacts both on agricultural labor force, as well as on staple crop yields, thereby accounting for the interacting effect of climate change on both land and labor. Here we analyze the two sets of impacts on staple crops, while also expanding the labor impacts to highlight the potential importance on non-staple crops. We find, worldwide, labor and yield impacts within staple grains are equally important at +3∘C warming, relative to the 1986–2005 baseline. Furthermore, the widely overlooked labor impacts are dominant in two of the most vulnerable regions: sub-Saharan Africa and Southeast Asia. In those regions, heat stress with 3∘C global warming could reduce labor capacity in agriculture by 30%–50%, increasing food prices and requiring much higher levels of employment in the farm sector. The global welfare loss at this level of warming could reach $136 billion, with crop prices rising by 5%, relative to baseline.
