TFP

TFP is an acronym with multiple meanings in different fields. The two most common are Total Factor Productivity in economics and Trade-for-Print (also Time-for-Print) in photography and modeling.

Total Factor Productivity (TFP) measures how efficiently inputs such as labor and capital are transformed into output. It captures innovation, technology, and other factors not explained by quantities of inputs. In growth accounting, TFP is the residual after accounting for capital and labor, and it helps explain long-run growth and cross-country differences. TFP is not directly observed; economists estimate it from production functions and statistical methods. Changes in TFP reflect improvements or declines in efficiency, technology, institutions, or organizational practices.

Trade-for-Print (TFP) is a collaborative arrangement in which photographers and models exchange time and services for prints or digital images rather than money. It is commonly used to build portfolios and gain experience. Terms are typically set in a release or contract, covering image ownership, usage rights, and the shoot's scope. TFP shoots carry no guaranteed pay; outcomes depend on mutual benefit and delivered images.

Other uses of the acronym exist in different industries, but they are less common, so context usually clarifies the intended meaning.
