Investicinius

Investicinius is a term used in economic theory and modeling to denote a synthetic indicator of investment propensity within an economy. It is designed to capture the willingness of investors to allocate capital to productive assets, accounting for risk, expected return, liquidity, and policy environment. The term appears in several contemporary simulations and theoretical papers, often as a complement to traditional metrics such as gross capital formation and investor sentiment indices.

Etymology and origins: The word combines Latin roots related to “investire” to invest and a diminutive suffix “-cinus,” used in some academic coinages. It was proposed by researchers in the early 2010s to create a flexible, model-friendly proxy for investment behavior.

Calculation and interpretation: In its typical form, investicinius is a dimensionless index computed within a simulation by normalizing net investment (real capital formation minus disinvestment) against potential investment capacity, then applying a liquidity-risk adjustment. Values range roughly from 0 to 1, with higher values indicating stronger investment propensity. In empirical settings, it is calibrated using historical investment flows and policy variables, then used to drive agent decisions.

Applications and limitations: Investicinius serves as a synthetic proxy in macroeconomic and agent-based models to study shocks to investment, financial frictions, and policy responses. It is not a standardized external statistic and varies by model, which raises comparability concerns. Critics note that it can obscure real-world determinants of investment if mis-specified.
