Endogenous Unions Formation

This paper analyzes the process of endogenous union formation in the context of a sequential bargaining model between a firm and several unions and tries to explain why workers may be represented by several unions of different sizes. We show that the equilibrium number of unions and their relative size depend on workers' attitudes toward the risk of unemployment and union configuration is independent of labor productivity.

Union Formation and Bargaining Rules in the Labor Market

This paper analyzes union formation in a model of bargaining between a firm and several unions. We address two questions: first, the optimal configuration of unions (their number and size) and, second, the impact of the bargaining pattern (simultaneous or sequential). For workers, grouping into several unions works as a price discrimination device which, at the same time, decreases their market power. The analysis shows that optimal union configuration depends on the rules that regulate the bargaining process (monopoly union, Nash bargaining or right to manage).

Enirio-Aralar mendietako abereen eta basoen ustiapena aro berrian zehar

[EUS]Enirio-Aralarreko mendietako basoek ez dute XVIII. mendera arte ustiapen gogorrik jasango. Ordura arte Batasunetako biztanleek behar zuten egurra soilik ateratzen zuten, ia ustiapen industrialik gabe. XVIII. mendean, beheko aldeko hariztiak agortu zirenean, Enirio-Aralarreko pagoak hasi ziren ustiatzen ikatza, itsasontziak edo arma-kajoiak egiteko. Aldi berean, ordura arte “tokian tokiko” abeltzaintza izan zena, erdi trashumantzia bihurtu zen: kostaldeko eta inguruko artaldeak Enirio-Aralar mendietan hasi ziren uda ematen. Aipatutako bi faktoreek –basoaren ustiapenak eta kanpoko artaldeen etorrerak–, batik bat XVIII. mendearen bukaeran eta XIX. mendearen hasieran, Enirio-Aralarreko basoaren atzerakada eragin zuten. XIX eta XX. mendeetan zehar deforestazioa areagotu egin zen, bertako mendiei gaur egun ezagutzen dugun itxura eman arte.

A reflection on the future of the quality management paradigm in the EU

In recent years, the Quality Management Paradigm has successfully taken root in the European Union’s business environment. Quality management besides being a multivariate issue including matters from management and economics till engineering may be called a global knowledge in permanent bubbling. This theoretical article is an eclectic effort to analyse the evolution of the Quality Management Paradigm. More specifically, the article deals with this management Paradigm evolution and change according to the present and future expected business environments.

Results on proximal and generalized weak proximal contractions including the case of iteration-dependent range sets

This paper presents some further results on proximal and asymptotic proximal contractions and on a class of generalized weak proximal contractions in metric spaces. The generalizations are stated for non-self-mappings of the forms for and , or , subject to and , such that converges uniformly to T, and the distances are iteration-dependent, where , , and are non-empty subsets of X, for , where is a metric space, provided that the set-theoretic limit of the sequences of closed sets and exist as and that the countable infinite unions of the closed sets are closed. The convergence of the sequences in the domain and the image sets of the non-self-mapping, as well as the existence and uniqueness of the best proximity points, are also investigated if the metric space is complete. Two application examples are also given, being concerned, respectively, with the solutions through pseudo-inverses of both compatible and incompatible linear algebraic systems and with the parametrical

Enplegua eta Lan Harremanen aldaketak XXI.mendean.

[EU] Gradu amaierako lan honetan, XXI.mendeko Lan Erreforma adierazgarrienak kronologikoki erakusten dira, hauetako bakoitzean, hurrengo lau aldagai hauen analisiaren bitartez, hain zuzen, kontratazioak eta enplegua, langabezia, pentsioak eta negoziazio kolektiboa. Gainera, ELA, LAB, CCOO eta UGT sindikatuei elkarrizketa bat burutu zaie, erreformei buruzko iritzia jaso eta kolektibo bakoitzaren ezinegonak eta parekotasunak ezagutzeko helburuarekin. Era honetan, analisi zehatz honen bidez, XXI.mendean zehar enpleguan eta lan harremanetan emandako aldaketak islatzea da funtsezko xedea.
