Well because in the theoretical situation of https://en.wikipedia.org/wiki/Post-scarcity_economy or "we already have all the goods we ever need" there'd not be any possibility for adding value, except for maybe transferring existing stuff around (while we already have infinite energy, etc.).

@mavavilj 1. post-scarcity economy is not what you describe. That is an economy when production severely outpaces demand, not an economy where goods are reused. For example, a post scarcity in pizza market would mean so many pizzas are actually being produced that even at nearly zero price you can completely fill yourself. You can't have second hand food so you can't simply not produce in post scarcity economy

2. even second hand stores are adding value through services they provide even though goods themselves do not add any extra value. In addition as already mentioned in my answer this is moot point. There are already plethora of economic models where you have endowment economies where added value is literally 0. People just trade endowments.

Well post-scarcity in the sense of achieving it through minimalism, rather than production technology. It's evident that once demand stifles, then so does supply, but then the question is, what does happen to a modern economy if everyone decided to become ascetics?

@mavavilj 1. that is not post scarcity, since people would still have to consume food etc. and it would not become abundant just because people want to live ascetically. 2. again the same answer as above applies. You could use the same models to analyze that situation. In terms of GDP growth it would result in sharp decline in GDP but it would not break any economic model per se

How does a lack of incentive to purchase new stuff affect economics?

I've perceived as if a lot of economics is rooted in the idea of continued innovation and consumption, but then I've realized that a lot of what's considered "old" by some standards has still rather good use value. That old game console, those old vintage clothes, ...

How does such "recyclist" paradigm affect economics?

Is it about just new models of businesses or does it break some fundamental assumptions about e.g. monetary policies? If, for example, value is based on added value, which reusing already produced stuff may not carry.

This would lower demand for the 'new stuff', meaning all else equal new goods would have lower prices than in absence of resale market.

> I've perceived as if a lot of economics is rooted in the idea of continued innovation and consumption, but then I've realized that a lot of what's considered "old" by some standards has still rather good use value. That old game console, those old vintage clothes, ...

This is not completely correct perception. Innovation plays big role in theories of economic growth, that is theories that try to explain why societies become more prosperous over time in a sense they are allowed to produce more with less. However, economic growth is just one of the subfield of macroeconomics, which is already subfield of economics.

In most economic theories, and most areas of economic research, innovation does not play big role. You can see from good graduate level textbooks such as Varian Microeconomic Analysis or MWG Microeconomic Theory or even Romer Advanced Macroeconomics that most models do not deal with innovation.

When it comes to consumption, consumption features heavily in most economic models, but in economics jargon consumption means something different than in day to day English. In economics, even spending time with your friends and family would be considered consumption (leisure consumption to be precise - see above mentioned sources) since consumption in economics is defined as 'final' use of resources, goods and services. Final meaning these goods and services or resources are used to satisfy your needs, whether those needs are food or shelter or socialization with friends, as opposed to using goods or services for future production (see [Oxford dictionary of economics](https://www.oxfordreference.com/display/10.1093/acref/9780198759430.001.0001/acref-9780198759430-e-550?rskey=NYZBks&result=1)). So while economic theory discusses consumption a lot, it is not only focused on consumption of newly produced goods or services (e.g. you have lot of endowment models where people just trade already existing goods), and it also includes variety of activities that would not be considered consumption in layman's vernacular like simply enjoying your free time.
