A regrettably rushed lecture by the founder of econometrics and (joint) first Nobel laureate in economics. You can already see in Tinbergen the seeds of the Structural Causal Model framework for causality: he describes how one would go about constructing the SCM, separating exogenous terms, computing causal coefficients etc. It's intriguing that he credits the origin of "path-specific" analysis to psychology, rather than Wright's heredity studies.
Also fascinating is his description of fairness: compensatory incentives vs. scarcity rents for labour.
