The paper presents a theoretical model and its simulation to explore the process of the fall of nations by focusing on moral and cultural decline, as well as military overstretch. In the model, a representative agent divides his time among military spending, material production, the consumption...

Workers learn on the job from both repetition and peers. Less understood is how specific types of experience and peer characteristics affect on-the-job learning. This likely differs by context (e.g., occupation, tasks, or roles). Absent such knowledge, it is unclear how to optimally assign...

This paper explores learning-by-doing in the context of creative tasks using detailed data on fiction writers from a digital publishing platform. I construct measures to quantify authors' performance over time and document significant variation in both starting levels and rates of improvement....

Although early human capital theory recognized the relevance of workers' experience, its focus was on education and formal training. More recent studies show that much of the performance of newly hired workers is driven by learning by doing or learning from peers or supervisors in the workplace....

Here, we study vertical foreclosure in a dynamic setup with learning-by-doing production technologies. There is a downstream monopoly and an upstream duopoly, where manufacturers produce differentiated products and can gain proficiency through the accumulation of their production. We study the...

Workers acquire skills through formal schooling, through training provided by governments, and through training provided by firms. This chapter reviews, synthesizes, and augments the literature on the last of these, which has languished in recent years despite the sizable contribution of firm...

This paper studies wage effects and job mobility as a result of skill mismatch in worker- occupation pairs. I develop a Roy model in which learning on the job induces workers to shift more time towards job-specific activities. Using a short task panel containing data on worker's time allocation...

Here I map Big Tech clouds focusing on the making of asymmetric relations with the different type of involved organizations. Amazon, Microsoft, Google and Alibaba are cloud hegemons that control every inch of their clouds. The cloud is the main means of adoption of digital technologies. As such,...

The term "network effects" has a clear meaning in economics but non-economists often confuse it with other concepts such as increasing returns to scale and learning-by-doing. This essay is an attempt to clear up some of this confusion

In this paper we develop the first model to incorporate the dynamic productivity consequences of both the spending effect and the resource movement effect of oil abundance. We show that doing so dramatically alters the conclusions drawn from earlier models of learning by doing (LBD) and the...

This paper investigates the sources of wage growth over the life cycle, where individuals have the possibility to acquire vocational training at the start of their career. Wage growth is determined by sectoral and firm mobility, unobserved ability and the accumulation of human capital. Workers...

Learning-by-doing is a fundamental concept in economics but a challenging one to document in high-skilled settings due to non-random assignment of workers to tasks and lacking performance measures. Our paper overcomes these challenges in the context of heart attack treatments in Sweden, where we...

Entrepreneurship is considered a key driver for economic growth. Therefore, more and more studies are investigating the role and effectiveness of entrepreneurship education. In this context, the present study is aimed at investigating the effectiveness of entrepreneurship programs, with a...

This paper views teacher quality through the human capital perspective. Teacher quality exhibits substantial growth over teachers’ careers, but why it improves is not well understood. I use a human capital production function nesting On-the-Job-Training (OJT) and Learning-by-Doing (LBD) and...

The paper examines the relevant cost benefit framework for public authorities investigating the potential of local projects to mitigate climate change. Because these projects are typically limited in time and space, continuation pathways need be introduced to capture the benefits provided by a...

Decarbonization requires the transformation of power markets towards renewable energies and investment costs are decisive for the deployed technologies. Exogenous cost assumptions cannot fully reflect the underlying dynamics of technological change. We implement divergent learning-by-doing...

Ziel dieser Arbeit ist es, Innovationen außerhalb von F&E zu beleuchten und zu einer breiteren und tieferen Wertschätzung von Lern- und Wissensschaffungsprozessen beizutragen, die für mitarbeiter- und individuumsgesteuerte Innovationen entscheidend sind. In mehreren Papern wird gezeigt, dass...
