We outline an education-career investment model structured for customizable, just-in-time delivery. Our initiation of this evolutionary model results in a pilot application for which we include associated technical details. We suggest how a FinTech collaboration can leverage the power of distributed expertise to support human capital investment planning via a robo-advising web application.

Does mobile broadband subscription rates have a positive effect on closing the earnings gap? Examining United States county level data, higher rates of mobile broadband subscription lead to reductions in the earnings gini coefficient. Specifically, a one standard deviation increase in mobile broadband subscription rate (8.5%) among counties' adult working population lowers the earnings gini index by 0.018. Additionally, mobile broadband subscription rate increases lead to rising average earnings, is associated with the highest increase in earnings at the 40th to 50th percentile, and has an alleviating effect on annual county level unemployment rates. To ascertain causality, a novel instrumental strategy exploiting county level elevation ruggedness is used to obtain the result. I also find preliminary evidence that mobile broadband raises the average earnings of workers in occupations for which their jobs or tasks are top ranked among mobile jobs platforms postings.

Spanish abstract: En la agenda de las universidades, el emprendimiento se encuentra como un tema prioritario. Sin embargo, la mayor parte de las veces los proyectos realizados por los estudiantes se quedan en el ámbito escolar. ¿Qué elementos son necesarios incorporar para transitar de un programa universitario de emprendimiento que genera proyectos escolares hacia uno que impulse la generación de proyectos viables y reales? En este artículo se analiza la evolución del programa de emprendimiento conocido como “Talents and Innovation Forum” (TIF) realizado, desde 2015, en una universidad mexicana. El objetivo de esta contribución es identificar los elementos que se incorporaron para que el TIF transitara de un programa de emprendimiento universitario ligado a un curso escolar hacia un programa de preincubacion con la participación voluntaria de los estudiantes y con la concreción de proyectos viables. La investigación fue de corte longitudinal y se utilizó la metodología del estudio de caso para analizar la evolución durante el periodo 2015 a 2019 del TIF, los instrumentos diseñados y aplicados fueron entrevistas en profundidad con actores clave y la “Encuesta de Percepción sobre el Emprendimiento e Incubación” aplicada a los ganadores de las tres últimas ediciones. Los resultados señalan que si bien el involucramiento de los estudiantes es fundamental, de mayor relevancia son tanto la formación practica para desarrollar las ideas como contar con el financiamiento para que los proyectos sean factibles. La limitación de esta contribución es que se enfoca en un estudio de caso, para una mayor comprensión del emprendimiento se debe realizar un estudio más exhaustivo.

Abstract We show that under multitasking — where tasks can be substitutes or complements — a specialist worker with an uneven skill distribution can outperform a generalist with higher average skills. We use a principal–agent model to study worker efficiency and welfare. The main result is robust if a rent-efficiency trade-off is added.

Making use of an international survey that directly assess the cognitive skills of the adult population, I document systematic differences in the effect of skills on job mobility across the 37 countries in the sample. While economic growth is associated with relatively higher job mobility among skilled workers, the prevalence of information and communication technology (ICT) in the workplace is associated with relatively lower job mobility among skilled workers. The documented patterns are in line with Schumpeterian growth models of creative destruction in which skilled workers transition to jobs with advanced technologies more easily.

We develop measures of firm-level human capital creation from publicly disclosed personnel expenses (PE) and examine the stock market valuation of these characteristics. Separately measuring human capital creation efficacy and opportunity, we first show that efficacy is positively associated with characteristics of human-capital-intensive firms and employee productivity growth. Next, we find that efficacy has a positive pricing coefficient, implying that the market recognizes some of its variation. In our main analysis, long-short portfolios based on the human capital creation efficacy (opportunity) produce annualized abnormal returns of 4.0 to 5.4% (6.0 to 7.5%). Portfolios formed on the combination of efficacy and opportunities produce the strongest abnormal returns of 6.3 to 9.3% in annualized terms. Our results provide evidence of the importance to valuation of accurate human capital measurement.

We develop and estimate a model of child care markets that endogenizes both demand and supply. On the demand side, families with a child make consumption, labor supply, and child-care decisions within a static, unitary household model. On the supply side, child care providers make entry, price, and quality decisions under monopolistic competition. Child development is a function of the time spent with each parent and at the child care center; these inputs vary in their impact. We estimate the structural parameters of the model using the 2003 Early Childhood Longitudinal Study, which contains information on parental employment and wages, child care choices, child development, and center quality. We use our estimates to evaluate the impact of several policies, including vouchers, cash transfers, quality regulations, and public provision. Among these, a combination of quality regulation and vouchers for working families leads to the greatest gains in average child development and to a large expansion in child care use and female labor supply, all at a relatively low fiscal cost.

The Kingdom of Saudi Arabia (KSA) considers education a top priority, and more emphasis has been placed on this following the 2016 announcement of Saudi Vision 2030. Since then, the country has witnessed several economic and social changes. As a result, the Kingdom has initiated a plan to invest in human capital through education to diversify its economy and increase employment. This includes educational reform with regard to primary and secondary education geared toward preparing students for higher education and the workplace. However, several factors may hinder the successful execution of this plan. This report will provide insights into factors such as cultural dimensions, learning profiles, the English language proficiency gap, and information on borrowing educational models from the West. It will also include some suggestions and recommendations to enhance teacher education programmes so that positive educational reform may be achieved effectively.

This paper aims to observe the evolution of skilled labor demand and relative wages during the rapid industrialization period. Although this historic episode has attracted the researchers’ attention, the evolution of skill demand and its impact on inequality remained as a black box. To provide first-hand evidence, I construct a 3-digit industry-level dataset that covers 1955-1980 from the Mining and Manufacturing survey. Then I measure skill demand and relative wages following the skill-biased technological change literature.
Analysis results show that Korea experiences drastic skill upgrading during its rapid industrialization. The nonproduction workers’ share in wage bill increased throughout the 25 years of 1955-1980. Relative demand rose much faster in industries that were initially less skill-intensive but accumulated capital through investment faster. This implies that there was a strong skill-capital complementarity. Increasing skill demand and skill-capital complementarity are a force of increasing skill premium in wages and wage inequality. It was so until 1973.
However, since then relative wages fell while skill demand kept rising. This is unique to the Korean experience, It also implies that the supply of skilled labor expanded even faster than the skill demand. Although it is possible to connect this to the heavy-chemical industrialization, falling skill premium and inequality was most driven by the “within” or common effect. Furthermore, emerging heavy-chemical industries had greater skill demand, therefore a positive effect on relative wage.
