  • A Matlab Algorithm for the Resolution of Fourth Degree Equations
    • Authors: Alessia Donato
      Pages: 7 - 18
      Abstract: In this article,  we propose  an algorithm for the resolution of fourth degree equations,  explicitly showing the solution method used, and we compare the results ob- tained with the Matlab “root” command.

  • Insurance-markets Equilibrium with Sequential Non-convex Market-Sector and
           Divisible Informal-Sector Labor Supply
    • Authors: Aleksandar Vasilev
      Pages: 19 - 32
      Abstract: This  paper  describes  the lottery- and insurance-market equilibrium in an economy  with non-convex  market-sector employment  and  informal  sector  work.   In contrast  to Vasilev 2016a, the discrete-continuous labor supply decision  in this paper is a sequential  one,  and instead  of  home  production,  we focus  on informal  activity. The presence of non-convexity requires that an insurance market for market-sector employment  be put in operation to achieve  market  completeness.  In addition,  given that the labor  choice  for  market  work and informal-sector hours is made  in succes- sion,  the  insurance  market  for  market  employment  needs  to  close  before  the  labor supply choice  in the grey economy  is made.  This  timing is reminiscent of the results obtained  in Vasilev  2016b) and also  a direct  consequence of the sequential  nature  of the discrete-continuous sectoral  labor supply decision.

  • Filters and limits in filtered spaces
    • Authors: David Carf`ı
      Pages: 33 - 82
      Abstract: In this lecture  notes,  we study filters and limits in a feasible  sufficiently general  way for  many  applications  to  Physics,  Economics and  Social  Science.    In particular  we analyze:
      Filters;
      Filter bases;
      Basic example in topological  spaces;
      Basic examples in preordered spaces;
      Filtered spaces;
      Induced filter bases;
      Examples in topological spaces;
      Examples on the real line;
      Limits;
      Limits with respect to filter bases;
      Limits with respect to filter bases  on subspaces;
      Limits and topology;
      Limits of functions on topological  spaces;
      Limits of functions on a topological  subspace;
      Some basic theorems for topology;
      Unicity of the limit in Hausdor spaces;
      Limits and functionals;
      Limits for real functional;
      Limits and operations;
      Local boundness;
      Complements;
      Limits and convergence of filtered bases;
      Limit of composition.

  • A Glance at Solow’s Growth Theory
    • Authors: Daniele Schilir`o
      Pages: 83 - 103
      Abstract: This article examines  the growth theory of Robert Solow1 , which has been a point of reference of economic growth since  the 1950s.  First,  the article  analyzes the  path-breaking  model  of  growth contained  in Solow’s  article  “A Contribution  to the Theory  of  Economic Growt”  published  in  The Quarterly Journal of Economics (1956).  Second,  it looks at the contribution  of Solow to growth accounting  and to the new method of studying capital formation  in economic growth through the vintage ap- proach.  Therefore, the work analyzes the article  “Technical Change and the Aggregate Production  Function”  published in The Review of Economics and Statistics (1957). In the latter  publication,  Solow,  through the aggregate  production  function,  tries  to measure  growth and provide  an explanation  of the nature of technical  progress.   The article  also examines  Solow’s 1960 essay “Investment  and Technical Progress”  based on the hypothesis  of embodied  technological  progress  and the vintage approach.
