Ερευνητικό Δοκίμιο no 11/25 με τίτλο "How High will our Buildings Become?"

του Άγγελου Αγγελόπουλου

Περίληψη

We have clearly reached a point where the know-how and the budget of heightening buildings has been acquired almost everywhere, i.e., nearly all over the world. So one may be reasonably start wondering: How tall will the buildings in our residential neighborhoods eventually become? Will the (upward) vertical expansion of buildings carry on forever? By exploiting several of the most basic and pristine principles of the neoclassical economic theory and of the mathematical theory of martingales, this paper argues (to wit, proves rigorously) that the acute perception (or, formally, the expectation) that we currently have as an answer to the previous question can hardly ever change in the long-run, by getting re-adjusted towards even higher buildings, no matter how much more pressing will the urbanised circumstances be in the earth's distant future. This then naturally brings us to the following conclusion: the expected average length of buildings is already (or will be quite soon) in a steady-state, so, in the long-run, our output (thus, our welfare and prosperity), which is (optimistically) expected to be (harmonically) strictly positively growing up to its own steady-state, cannot grow our buildings distinctively taller any more. Hence, according to this paper's neoclassical foundation at least, wealth and skyscrapers shall not be necessarily synonymous, and will not be going hand in hand in the future.

του Άγγελου Αγγελόπουλου

Περίληψη

The intention of this paper is to: (i) model a situation of randomly (in time and in space) picking and observing a number of patients inside some emergency room, of some hospital or some clinic, waiting to receive personalised (and individually optimal) treatments, (ii) de ne a Walrasian or a competitive general equilibrium for this situation and (iii) prove, under generic conditions, that such a general equilibrium exists for this emergency room and its patients, while it is Pareto optimal (i.e., efficient with respect to all the patients' treatments together) and individually rational.
