Voluntarily contributing to a public good (such as Wikipedia) is a strong social norm. The tendency to follow such norms even if this is costly in the short run has developed over humans' evolutionary history, as in small to medium-sized hunter-gatherer communities this behavior was adaptive, e.g. due to reputation effects ("community enforcement")....

I wouldn't underestimate the role of learning by answering. Drafting a significant text typically forces a person to put their thoughts in order, to engage in research, and then to structure the information for the purpose of recording and conveying it. It is not unusual that further insights or questions emerge during this process, the answerer certainly ...

tl;dr: There could be multiple explanations depending on how you want to treat Wikipedia. If you want to treat Wikipedia as public good where everyone contributes a small part towards its creation and that everyone then enjoys equality you can explain it as people trying to still satisfy their own preferences through consuming the final Wikipedia page. You ...

Look at the data For starters, the obvious thing is to look at the data about the self-reported reasons for contributing to wikipedia (and I'm surprised that neither the question asker nor most of the answers have done so). For example, Wikipedia itself has a section on the motivation that refers to multiple studies - though many of them are behind a paywall ...

Calculating a precise strike time without additional details is - in my opinion quite clearly - impossible. On the question of how to do this with additional info/assumptions: A straightforward solution would be to make M time dependent - the larger the time elapsed, the smaller M is. Sounds like you do not want to do this. Base problem Let us now assume M ...

I used to work for a major online advertising network, and it's pretty much an open secret in the industry that a substantial portion of ad impressions are either bot-generated, scams to exploit misleading search engine results, or both. There are typically several layers of "middlemen" involved between the company whose products are being advertised and ...

I haven't gone through all the papers so I just sampled 'The Firm as an Incentive System'. Browsing through it, it relies on Linear Algebra and Real Analysis. Again, I warn that I have not gone through the entire paper but seeing some of the terminology used there, I could guess that these two a clearly involved (maybe they use some bit of topology as well). ...

Could you provide examples of business models, where the service provider gets rewarded for things not happening (or at least not deteriorating). I think you're asking for examples of businesses that thrive on preventing "bad things" from happening. There should be plenty of those: Security firms prevent financial and physical losses to their ...

Since the authors state that the total labor input is: $$\int t_i(k)dk$$ the meaning of the total labor input in this case would be that it is the sum of all attention $t_i$ allocated over those tasks $k$. For example if we would assume that $t_i (k) = k$ then the labor supply across continuum given by $[0,1]$ would be equal to $\frac{1}{2}$ because $\int k ...

Deloitte managed a semi-intelligible explanation. It's called "super" when an income tax deduction is applied twice for the same item (e.g. for R&D)... In early 2015, Slovakia introduced a new type of tax incentive aimed at supporting companies conducting corporate R&D (most common is development of new or substantially improved products, services,...

Yes, it is essentially the same idea as with just one unit. For example, see the text leading to Proposition 14.1 in the book "Auction Theory" by Vijay Krishna. Let $x$ be the vector of willingness-to-pay. Define $U(x) = \max_z \{ q(z)x - m(z)\}$ as the equilibrium utility of type $x$. The incentive compatibility (I am quoting Krishna now) "...

I am not a data person. So I can only provide insights into the theoretical incentives behind the phenomenon. Moreover I think that there are multiple forms of such web spam and each is rooted in distinct incentives. Hence, there is not a single true answer. Let me first express my view on classical (email) spam and relate it to what you have in mind. I will ...
