Just two remarks. One. The idea of skills is not only bad. Knowledge is essential (although not the only condition) for the sound functioning of people. Education allows individuals to shape their own identity, and to develop into unique and valuable citizens. Two. Common labour economics does not assume, that the labour market clears. Everybody is well aware, that the labour market is bound by institutions. A set of institutions must be compatible. Firms can be a monopsony, and unions create a monopoly. Raising the minimum wage may lower employment, but it can also increase employment. My impression of labour economics is, that we do not yet know much about causes and consequences. Rigorous interventions are risky. In general incremental trial and error is the best way to find what works.Emil Bakkumhttp://www.hgdewolff.comnoreply@blogger.comtag:blogger.com,1999:blog-26706564.post-23576293572591056812021-12-30T09:22:35.683-05:002021-12-30T09:22:35.683-05:00Thanks for the suggestion.

One is to keep within the neoclassical framework from Steedman and Opocher and relate Card's achievements with the phenomena of recurrence. To be more clear, accepting the framework of well-behaved functions. So there can not be a whole-economy effect of rising employment.<br /><br />The other is to see it through the optics of non-differential functions and maybe to extend the analysis to the opening of the numeràire or more rightly to the opening of both rates of wages and profits on a non-uniform level so the pattern spaces for global rising wages following rising employment can gain some area on the plot.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-26706564.post-12475807259456394082021-10-12T08:21:06.243-04:002021-10-12T08:21:06.243-04:00Maybe it’s time to go back.

The geometry is like algebraic geometry in that we are interested in solutions to equations involving polynomials, but where traditional algebraic geometry gives rise to deeply inaccessible research efforts like the Langlands program, equations involving tropical polynomials are really easy to work with.<br /><br />While given what I gather to be you grasp of linear algebra I don't think it would take much time for you to get the basics of tropical algebra, the point of my comment was not to recommend that you do that. Rather, it's that I think the results you are putting together are getting to the point that it is possible that they might be a jumping off point for some quite appealing applied mathematics. The point about simplicity is that if a mathematician were willing to take this idea up, I am guessing that you would not find it so hard to follow what they were doing.

My fluke cases impose some other conditions.<br /><br />Algebraic geometry considers how some structures in some space of coefficients relate to the solutions of systems of polynomial equations.<br /><br />I do not understand algebraic geometry and have never heard of tropical geometry before. If I want to draw on bifurcation theory, I must connect up my results to some sort of (cross-dual?) dynamics.<br /><br />I will probably continue to present what I am doing as exploratory mathematics.<br /><br />Kurz and Salvadori's 1995 textbook is probably still the most comprehensive presentation of post-Sraffian price theory.
