Hiring Incentives and Labour Force Participation in Italy

A long-standing economic tradition maintains that labour supply reacts to market tightness; its sensitivity to job quality has received less attention. If firms hire workers with both temporary and open-ended contracts, does participation increase when more permanent jobs are available? We investigate this relationship within a policy evaluation framework; in particular, we examine how labour supply reacted in Italy to a recent subsidy in favour of open-ended contracts. This subsidy increased labour force participation by 1.4% in 2001 and 2.1% in 2002. This increase was concentrated on males aged 35-54, with a low or at most a secondary schooling level.

Influence of the Graphical Levels of Detail of a Virtual Thrower on the Perception of the Movement

Virtual reality has a number of advantages for analyzing sports interactions such as the standardization of experimental conditions, stereoscopic vision, and complete control of animated humanoid movement. Nevertheless, in order to be useful for sports applications, accurate perception of simulated movement in the virtual sports environment is essential. This perception depends on parameters of the synthetic character such as the number of degrees of freedom of its skeleton or the levels of detail (LOD) of its graphical representation. This study focuses on the influence of this latter parameter on the perception of the movement. In order to evaluate it, this study analyzes the judgments of immersed handball goalkeepers that play against a graphically modified virtual thrower. Five graphical representations of the throwing action were defined: a textured reference level (L0), a nontextured level (L1), a wire-frame level (L2), a moving point light display (MLD) level with a normal-sized ball (L3), and a MLD level where the ball is represented by a point of light (L4). The results show that judgments made by goalkeepers in the L4 condition are significantly less accurate than in all the other conditions (p
