How Jan Tinbergen might approach Economics

The very notion of "Economics" as a field of inquiry demands precision in definition and purpose. We are not merely observers of markets, but engineers of prosperity, tasked with understanding and influencing the complex machinery of production, distribution, and consumption. To speak of economics without acknowledging the necessity of quantification is akin to a bridge builder discussing structural integrity without recourse to physics.

Let us first define our target variables. What are we aiming for? Is it merely aggregate growth, or are we also concerned with the equitable distribution of its fruits? The social welfare function is our ultimate criterion, and its components must be measurable: employment levels, price stability, the reduction of poverty, and the sustainable use of our planet's resources. Without these clearly delineated targets, our efforts risk becoming diffuse and ultimately ineffective.

The data must guide our theory, not the other way around. We observe the fluctuations of output, the ebb and flow of prices, the patterns of investment. From these empirical regularities, we must construct structural equations that capture the underlying causal relationships. This is not to say that theory is secondary; rather, it is the framework through which we interpret the data. A well-formulated model, rigorously tested against evidence, allows us to move beyond mere description to prediction and, crucially, to intervention.

We need a clear set of policy instruments. If our target is to reduce unemployment, what specific levers can we realistically pull? Are they fiscal adjustments, monetary policies, or perhaps more targeted interventions in specific sectors? The effectiveness of these instruments depends entirely on our ability to quantify their impact…
