Det är lite mening med vad jag säger …  [embedded content] Ständigt efterfrågad favorit i repris …

Consider a genuine challenge to: ‘April showers have always brought May flowers. So, that April is showery is a good reason for expecting May to be flowery.’ You question whether this is a good reason … How could I satisfy you as to the goodness of my reasons in the present case? That I have lived through 35 showery Aprils and flowery Mays in several parts of the northern hemisphere would be relevant. So would national and international meteorological records. So would botanical data...

The ‘journal game’ Many of the submissions do  not appear to be written in order to further economic knowledge. Whilst I fully understand the pressure on authors, particularly young academics, it is still disheartening that so many economists seem to be playing the ‘journal game’, i.e. producing variations on a theme that are uninteresting and which do not enlighten. John Hey (Managing Editor of The Economic Journal) Sad to say, if anything, things have gotten even worse since Hey wrote...

‘Observation is theory-laden’ — fashionable philosophical rubbish Now our slogan is that observation is theory-laden … The slogan cannot be literally true. If anything is ‘theory- laden’ it cannot be observation but rather statements made on the basis of observation. Observation is simply an act that humans and other creatures perform, a special kind of event or process occurring in the nervous systems of humans and other creatures.

‘New Keynesianism’ — little new and nothing Keynesian Not that long ago, Paul Krugman had a post up on his blog discussing ‘New Keynesian’ macroeconomics and the definition of necoclassical economics: Most of what I and many others do is sorta-kinda neoclassical because it takes the maximization-and-equilibrium world as a starting point or baseline, which is then modified — but not too much — in the direction of realism … New Keynesian models are intertemporal maximization modified with...

Why science necessarily involves a logical fallacy In science we standardly use a logically non-valid inference — the fallacy of affirming the consequent — of the following form: (1) p => q (2) q ————- p or, in instantiated form (1) ∀x (Gx => Px) (2) Pa ———— Ga Although logically invalid, it is nonetheless a kind of inference — abduction — that may be strongly warranted and truth-producing. Following the general pattern ‘Evidence  =>  Explanation  =>  Inference’ we infer...

The most important book in the history of economics [embedded content]
