The innovation ecosystem concept has been widely used as a framework to explain innovation activities within different industries. Despite the usefulness of this approach, the concept is under-theorized, especially with regard to the methodological issues. This article presents a new approach in...

This paper presents and estimates a unified model where both human capital investment and job search are endogenized. This unification enables us to quantify the relative contributions of each mechanism to life cycle earnings growth, while investigating potential interactions between human...

We construct a theoretical model of labor markets with human capital accumulation to understand and quantify the earnings losses for young workers generated by unemployment: unemployment represents time forgone in terms of human capital accumulation, which adversely affects long-term income...

This paper extends the standard model of life cycle consumption, saving and labor supply in a number of directions. First, it argues that consumption should be defined as expenditure on household production as well as on market goods, that is, we are interested in life cycle profiles of full...

We investigate how early life circumstances - childhood health and socioeconomic status (SES) - are associated with labor market outcomes over an individualś entire life cycle. A life cycle approach provides insights not only into which labor market outcomes are associated with adverse...

This paper investigates the age-dependency of participation andunemployment by integrating job search with intertemporal optimizing behaviorof finitely-lived households. We find that search frictions and tax ratesdistort the decisions of older workers to a much larger extent than that ofyoung...

This paper analyzes optimal linear taxes on capital and labor incomes in a life-cyclemodel of human capital investment, financial savings, and labor supply with heteroge-nous individuals. A dual income tax with a positive marginal tax rate on not onlylabor income but also capital income is...
