'This is a very vital and long-awaited e-book. The authors offer a cogent advisor to all that's unsuitable with the idea and empirical functions of the discredited thought of an mixture creation functionality. Their critique has devastating implications for orthodox macroeconomics.'
- Anwar Shaikh, New institution for Social examine, US

''There are none so blind as those that won't see.' for many years now John McCombie and Jesus Felipe were publishing papers which draw out the results of the conceptual vacuousness that characterises becoming mixture construction functionality necessities to facts to check the validity of the marginal productiveness idea of distribution, a critique first built through Henry Phelps Brown and Herbert Simon. through cautious empirical and theoretical paintings, they've got reached the realization that the large literature on mixture construction services and technical development is 'not even flawed' simply because predictions can't be demonstrated, that they're basically adaptations on manipulations of nationwide accounting identities. possibly this time it quite may be 'different', the scales will fall from the profession's eyes. I definitely desire so.'

'This is a vital booklet. Proofs that mixture creation services don't exist were round for greater than 50 years. This casts doubt not just on macroeconomic thought but additionally on empirical paintings and coverage. but, this has now not deterred macro-economists. The authors exhibit in nice aspect that the obvious 'fit' of such services to value-based information is a tautology and never an explanation that such aggregates exist. One hopes that the occupation will ultimately take note.'
- Franklin M. Fisher, Massachusetts Institute of know-how, US

'Felipe and McCombie have collected the entire compelling arguments denying the life of combination construction features and exhibiting that econometric estimates in response to those fail to degree what they purport to quantify: they're artefacts. Their critique, which must be learn by way of any economist doing empirical paintings, is damaging of approximately all that's vital to mainstream economics: NAIRU and power output measures, measures of salary elasticities, of output elasticities and of overall issue productiveness growth.'

This authoritative and stimulating ebook represents a basic critique of the mixture creation functionality, an idea wide-spread in macroeconomics.

The authors clarify why, regardless of the intense aggregation difficulties that encompass it, combination creation features frequently supply believable statistical effects. this is often end result of the use of constant-price price info, instead of the theoretically right actual information, including an underlying accounting id that relates the information definitionally. it truly is during this experience that the mixture construction functionality is 'not even wrong': it's not a behavioral dating able to being statistically refuted. The booklet examines the heritage of the construction functionality and exhibits how yes seminal works on neoclassical progress concept, exertions call for services and estimates of the mark-up, between others, be afflicted by this basic problem.

The ebook represents a primary critique of the mixture construction functionality and may be of curiosity to all macroeconomists.

The suggest values of capital’s and labour’s output elasticities are zero. 485 and nil. 537. For our reasons, it truly is worthy emphasising that the simulated macroeconomic info recommend an economic climate characterized through elements being paid their marginal items and an elasticity of substitution of cohesion, even supposing we all know that each enterprise is topic to a fixed-coefficients expertise. explanation why the nice healthy to the Cobb–Douglas creation functionality is located is once more as the issue stocks produced by way of the simulation are fairly consistent (see Nelson and wintry weather, 1982, desk nine. 1, pp. 218–19). Nelson and wintry weather (p. 227) summarise their findings as follows: On our examining, at the least, the neoclassical interpretation of long-run productiveness development is sharply various from our personal. it's in response to a fresh contrast among ‘moving alongside’ an present creation functionality and moving to a brand new one. within the evolutionary thought, substitution of the ‘search and choice’ metaphor for the maximization and equilibrium metaphor, plus the belief of the fundamental improvability of systems, blurs the idea of a construction functionality. within the simulation version mentioned above, there has been no construction functionality – just a set of bodily attainable actions. The creation functionality didn't emerge from that set since it was once now not assumed specific subset of the potential suggestions will be ‘known’ at every one specific time. The exploitation of the set used to be handled as a historic, incremental procedure during which non-market details flows between businesses performed a huge function and during which agencies particularly ‘know’ just one method at a time. SHAIKH’S (2005) NON-LINEAR GOODWIN version AND THE COBB–DOUGLAS creation functionality Shaikh (2005) presents extra facts of the trouble of estimating an combination construction functionality by means of extending his 1987 access within the New Palgrave.

The generated information also are in comparison with real information for the united states financial system over the postwar interval (taken from the USA Bureau of financial research nationwide source of revenue and Product Accounts). The generated information convey marked similarities to the particular facts and, back, as a result fidelity of the issue stocks, the latter provide an outstanding healthy to the Cobb–Douglas creation functionality.
