A versenyzői egyensúly létezése, egyértelműsége és hatékonysága mellett az általános egyensúlyelmélet egyik központi témája a stabilitás. A tanulmányban ezt a kérdést vizsgáljuk meg részletesebben, egy speciális áralkalmazkodási szabály feltételezésével. A standard...

The paper studies convex radiant sets (i.e. containing the origin) of a linear normed space X and their representation by means of a gauge. By gauge of a convex radiant set C c X we mean a sublinear function p : X == R such that C = [p <= 1]. Besides the most important instance, namely the Minkowski gauge mC(x) = inf {l > 0 : x e lC}, the set C may have other gauges, which are...</=>

We solve the stochastic neoclassical growth model, the workhorse of modern macroeconomics, using C++11, Fortran 2008, Java, Julia, Python, Matlab, Mathematica, and R. We implement the same algorithm, value function iteration with grid search, in each of the languages. We report the execution...

As residential broadband options such as cable and xDSL grow in popularity, broadband providers continue to roll out service in select market areas. However, due to technological limitations, some locations qualify for xDSL broadband service while others do not. The purpose of this article is to...

The aim of this paper is to investigate whether employee health is affected by the environment in which the individual works - in terms of both physical and psychosocial working conditions - and by his or her lifestyle. Health measures are computed from Danish data, and refer to both self...

This paper presents a new modelling framework for day–ahead electricity prices based on multivariate Lévy semistationary (MLSS) processes. Day–ahead prices specify the prices for electricity delivered over certain time windows on the next day and are determined in a daily auction. Since...

Labor market frictions are seen in many extensions of the classical human capital theory as a prerequisite for firms financing general training. The labor market reforms in Germany at the beginning of the millennium have therefore been seen by many as a danger to the firms’ willingness to...

A review of the literature on cost sharing solutions for the minimum cost spanning tree problem is proposed, with a particular focus on the folk and Kar solutions. We compare the characterizations proposed, helped by some equivalencies between sets of properties.
