Abstract We estimate how much firms differentiate pay premia between regular and outsourced workers in temp agency work arrangements. leverage unique Argentinian administrative data that feature links user (the workplaces where perform their labor) agencies (their formal employers). a high-wage firm pays worker 10% premium on average only 4.9% premium, compared to what these would earn low-wage...
Climate variables are known to be subject abrupt changes when some threshold levels surpassed. We use data for the last 798,000 years on global ice volume (Ice), atmospheric carbon dioxide level (CO2), and Antarctic land surface temperature (Temp) model measure those long-run nonlinear climate effects. The have very long asymmetric cycles, created by periods of upward trends, followed downward ...
A smartphone is said to be an extension of a mobile user’s oneself. It the ultimate device today for humans, one that humans cannot avoid using, leave behind when on move and becomes necessity own one. allows communicate perform many daily personal tasks. Smartphones continue evolve embedding advanced technologies, sophisticated processes applications. This symbiotic combination generates immen...
Smart systems require intefacing more of the world in an integrated solution (Camera, gyroscope, compass, temp, direction, ....). This is imposed by social evolution and enabled by new integration technologies. So far, many products featuring a variety of hardware and software have been developed and many more seems to be coming in a fast growing market. The panel will present the most promisin...

Adsorption kinetics for removal of arsenic was carried out by red mud and its mixtures with haematite, china clay and fly ash besides china clay-fly ash at: adsorbate conc., 5.0 mg1; particle size of adsorbent, <53 μm; agitation rate, 220 rpm; pH, 8.0; and temp., 30, 40 & 50°C. Data fit into Lagergren equation and adsorption follows first order reaction kinetics. As(III) removal by adsorbents i...

During the 1990s, temporary agency work has increased rapidly in most OECD countries. We augment the equilibrium unemployment model developed by Pissarides and Mortensen with temporary work agencies. Our model implies that technological improvements for placements and de-regulation of the sector caused the emergence and growth of temporary agency work. Simulations of a calibrated version of the...
