The Unemployment Volatility Puzzle: The Role of Matching Costs Revisited

Recently, Pissarides (2008) has argued that the standard search model with sunk fixed matching costs increases unemployment volatility without introducing an unrealistic wage response in new matches. We revise the role of matching costs and show that when these costs are not sunk and, therefore, can be partially passed on to new hired workers in the form of lower wages, the amplication mechanism of fixed matching costs is considerably reduced and wages in new hired positions become more sensitive to productivity shocks.unemployment volatility puzzle, search and matching, matching costs

Flexibility at the margin and labor market volatility in OECD countries

We argue that segmented labor markets with flexibility at the margin (e.g., just affecting fixed-term employees) may achieve similar volatility than fully deregulated labor markets. Flexibility at the margin produces a gap in separation costs among matched workers that cause fixed-term employment to be the main workforce adjustment device. Moreover, in the presence of limitations in the duration and number of renewals of fixed-term contracts, firms respond by fostering labor turnover which further raises the volatility of the labor market. We present a matching model with temporary and permanent jobs where (i) the gap in firing costs and (ii) restrictions in the use of fixedterm contracts play the central role to explain the similar volatility observed in many regulated labor markets with flexibility at the margin vis-à-vis the fully deregulated ones

Flexibility at the Margin and Labor Market Volatility in OECD Countries

We study whether segmented labor markets with flexibility at the margin (e.g., just affecting fixed-term employees) can achieve similar volatility than fully deregulated labor markets. Flexibility at the margin produces a gap in separation costs among matched workers that cause fixed-term employment to be the main workforce adjustment device, which in turn increases de labor market volatility. This increased volatility is partially reverted when limitations in the duration and number of renewals of fixed-term contracts are introduced. Under this scenario, firms respond by reducing the intensity of job destruction since it becomes more difficult to avoid firing costs in permanents contracts. We present a matching model with temporary and permanent jobs where (i) the gap in firing costs and (ii) restrictions in the use of fixed-term contracts helps explain the similar volatility observed in many regulated OECD labor markets with flexibility at the margin vis-à-vis the fully deregulated ones.separation costs, volatility, flexibility at the margin, matching model

Bauhaus Bodies, Modern Automatas and Other Performing Images

The Triadic Ballet Oskar Schlemmer 1922 and its Bauhaus theatrical gestures fine examples of the new modern society is a starting point to think of body image presentations along time in increasingly complex embodied affections A very diverse feminine body also emerges in representations of other modern artists as playing a character and of oneself as the creator in more subjective forms of visual composition Two approaches to body potential of imaging creation and gesture possibilities are presented in this chapter as an extension of how embodied realities may reconfigure performed bodies along time Since the 19th century our body is manipulated and recreated through various media languages experiencing an existence influenced by society science technology and culture A Schlemmer s contemporary German artist surrealist sculptor and photographer Hans Bellmer 1902-1975 presents Olympia from a body image related to other modern characters embodied in a manipulated doll with a spherical body in photography series resembling dead bodies from World War or denouncing a scientific desire to control and recreate living bodies as pleased since widely documented in medical protocols since the end of XIX centur

Nietzsche’s Idiosyncrasy Against Euripides

Lo scopo principale di questo articolo è presentare una critica alla lettura nietzscheana dello status valutativo della poesia di Euripide all’interno del processo storico-genealogico che il filosofo intende come costituente il declino della tragedia greca. Il carattere negativo - che presumibilmente radicalizza, rafforza e consuma questa ipotetica traiettoria di declino - della poesia euripidiana sarà qui imputato al condizionamento molto teorico della concezione nietzscheana del tragico. Per fare ciò, esploreremo tre linee guida fondamentali: (1) la subordinazione di Nietzsche a una linea interpretativa tradizionale; (2) il suo tendenzioso disprezzo per il contenuto concreto dell’intera opera euripidiana; (3) l’identificazione infondata tra Socrate ed Euripide.The main purpose of this article is to present a critique of the Nietzschean reading of the evaluative status of Euripides’ poetry within the historical-genealogical process that the philosopher understands as constituting the decline of the Greek tragedy. The negative character – supposedly radicalizing, potentializing and consuming this hypothetical trajectory of decline – of Euripidian poetry will here be imputed to the very theoretical conditioning of the Nietzschean conception of the tragic. To do this, we will explore three fundamental guidelines: (1) the subordination of Nietzsche to a traditional interpretative line; (2) his tendentious disregard for the concrete content of the whole Euripidian work; (3) the unfounded identification between Socrates and Euripides

Implementação de ações de promoção, prevenção e indicação de tratamento de saúde bucal na região de Bandeirantes - PR

Anais do 35º Seminário de Extensão Universitária da Região Sul - Área temática: SaúdeIntrodução: ​ Hoje no Brasil, quando se trata de saúde bucal (SB), ainda encontramos uma situação epidemiológica grave, que ocorre na maioria dos casos devido as condições sociais e econômicas da população brasileira, além da falta de informação sobre os cuidados com a saúde. No norte pioneiro, encontrou-se um nível de SB considerado crítico. O intuito principal do projeto é de intervenção, visando a prática de atividades educativas voltadas a escolares. ​ Objetivo: Aumentar o índice de informações e melhorar as condições de SB da população, promovendo a conscientização da mesma e consequentemente levando a mudanças de comportamento. ​ Metodologia: Trata-se de um relato de experiências oriundas do projeto de extensão “Saúde Bucal”, o qual promove ações educativas em SB para escolares em quatro escolas municipais da cidade de Bandeirantes-PR. ​ Resultados Parciais: Os resultados obtidos levam a crer que a ideia de implantar atividades educativas e preventivas em SB, normalmente geram as mudanças esperadas de hábitos em saúde em crianças e o maior desejo do autocuidado em relação a mesma e também pela oportunidade de interação do aluno de enfermagem criando elos entre a criança, sua família (criança age como disseminador de conhecimentos) e a higiene bucal. ​ Considerações finais: O projeto possui muita relevância no âmbito da saúde e se situa em situações de aprendizagem, não somente para os que recebem a ação, mas como para os alunos da graduação, os quais aprendem muito juntamente as crianças envolvidas no projet
