macromodeln.

Brit.

/ˈmakrəʊˌmɒdl/, U.S.

/ˈmækroʊˈˌmɑdəl/

Origin: Formed within English, by compounding. Etymons: macro- comb. form, model n.

Etymology: < macro- comb. form + model n. With spec. use in economics (see sense 1a) compare macro adj. 3(a). In sense 1b after macromodelling n. 2. Compare micromodel n.

a. A theoretical or conceptual model which deals primarily with the behaviour of a system as a whole, rather than that of its constituent elements; a model that takes into account large-scale, global, or systemic factors; (Economics) a macroeconomic model.

ΚΠ

1947 Econometrica 15 51 In particular, it would be interesting to know how technological changes in the micromodel are reflected in the macromodel.

1966 Acta Univ. Tamperensis A. 9 (heading) The effect of changes in the value of money on consumers' saving, on firms' investment, and on the equilibrium of a two-sector macromodel.

1979 Amer. Jrnl. Polit. Sci. 23 595 He has developed at a lower level a model which focuses on the actual process of the competition for power outlined in the macro-model.

1990 Industrial Engin. (Nexis) 22 49 A high level or ‘macro’ level model encompassing all major elements of the system was developed first. Macro models usually focus on overall system execution rather than detailed operation of individual components.

1998 Public Administrative Rev. (Nexis) 58 540 Guy Peters's The Future of Governing describes and examines four alternative macromodels that he sees emerging from the myriad reforms now being proposed by scholars, politicians, and the popular press: market government, participative government, flexible government, and deregulated government.

b. Electronics. In the computer simulation of electronic circuits: a model which represents a complex device or network as a circuit composed of elementary components, whose overall behaviour approximates that of the modelled device, while differing from the latter in configuration.

ΚΠ

1972 Internat. Conf. Computer Aided Design 263 To..predict the transient waveform at a given point in a system with multiple interconnecting and feedback paths, a transient Macro-Model is necessary.

1992 Electronic Design (Nexis) 40 73 In the interest of increasing simulation speed and simplifying development, Spice macromodels rely on ideal voltage- and current-controlled sources with resistors, capacitors, and a limited number of transistors and diodes.

1996 Electronic Design (Electronic ed.) 18 Nov. A macromodel is a behavior-model that uses an electronic-equivalent circuit to mimic the behavior of the chip. This equivalent circuit is much simpler than the transistor-level representation of the IC and approximately captures the dc, ac, and transient responses of the chip.

2. Chiefly Biology and Chemistry. A physical model of a small-scale (esp. microscopic) structure at a larger scale than the original, designed to simulate physical characteristics or behaviour which might be difficult to observe directly in the structure itself.

ΚΠ

1971 Nature 10 Sept. 141/2 We investigated the hydrodynamic behaviour of macromodels of differing dimer geometry... The scaled-up models were constructed from precision ground stainless steel rods.

1973 Jrnl. Theoret. Biol. 39 325 Dimensionally accurate transformation from sphere to biconcave disc and back to sphere is demonstrated in a dry macromodel of the red cell.

1989 Jrnl. Theoret. Biol. 140 185 A physical macromodel of the erythrocyte membrane was constructed to investigate the effect of intrinsic membrane precurvature on a unique, non-isotropic, composite material that dissipated shear energy but stored bending energy.
