Elementary techniques from operational calculus, differential algebra, and noncommutative algebra lead to a new approach for change-point detection, which is an important field of investigation in various areas of applied sciences and engineering. Several successful numerical experiments are...

We estimate the informal-formal sector pay gap throughout the conditional wage distribution using panel data from Brazil, Mexico and South Africa. We control for time-invariant unobservables and identification is stemming from inter-sector movers. We control for observables in a non-linear way...

In this paper we examine the consequences of a decrease in exits of older workers on youth employment, allowing for job-to-job áows. We distinguish between young workers with no experience and experienced workers and we consider jobs with di§erent experience requirements. Using a theoretical...

Multi-echelon distribution schemes are one of the most common strategies adopted by the transport companies in an aim of cost reduction, but their identification in scientific literature is not always easy due to a lack of unification. This paper presents the main concepts of two-echelon...
