Dennis M. Katkocin,Chia-Lung Hsiehc efficiency. We then tackle problems of an empirical nature. In this way, different ways of measuring efficiency are presented, with their main disadvantages. To finish, a theoretical application is presented for haulage firms operating in Spanish roads in six different sub-sectors with panel data.Blood-Clot 发表于 2025-3-23 15:57:25
7 Counting classes of annulus maps,ervices are a dynamic part of the economy and make an increasing contribution to employment and economic growth. Thus it could be argued that the “service or tertiary society” is the stage towards which all industrialised countries are moving.inchoate 发表于 2025-3-23 21:58:36

The traditional organisational model assumes, implicitly or explicitly, the extension of a natural monopoly condition from some of these stages to others. This is a consequence of the presumptive existence of strong, vertically-integrated economies. On the other hand, an increasiFactorable 发表于 2025-3-24 02:58:00
Mathematics and Its Applicationshe European countries. This proposal has had a strong effect on public opinion, since the “working-less-for-everyone-to-be-able-to-work” assumption seems to be a self-evident truth. But there is a fallacy involved in this assumption: the labour market is rather dynamic and neither the jobs available许可 发表于 2025-3-24 09:43:42
Combinatorial Computational Biology of RNAurns in both cases. The resource is owned by a few individuals who must choose between the two activities in which to use it. Here we analyse the decisions of change of activity in which the resource is to be used taking into account the different profitability per time unit of the activities direct狂热语言 发表于 2025-3-24 12:28:37

Cluster Algebras and Amplituhedra,A wide range of studies devoted to recent evolution of international trade highlights the fact that a significant and increasing proportion of flows consists of bi-directional change of products belonging to the same industry. This phenomenon is known as intra-industry trade.
