The Relevance of Post-Match LTC: Why Has the Spanish Labor Market Become as Volatile as the US One? We present a Search and Matching model with heterogeneous workers (entrants and incumbents) that replicates the stylized facts characterizing the US and the Spanish labor markets. Under this benchmark, we find the Post-Match Labor Turnover Costs (PMLTC) to be the centerpiece to explain why the Sp...

[1] Diurnal cycles in snow-fed streams provide a useful technique for measuring the time it takes water to travel from the top of the snowpack, where snowmelt typically peaks in the afternoon, to the river gauge, where the daily maximum flows may arrive many hours later. Hourly stage measurements in nested subbasins (6–775 km) of the Tuolumne River in Yosemite National Park illustrate travel ti...

We propose Open Ontologies and Open Knowledge Bases as means for the acquisition, evolution and representation of socially (but not necessarily cooperatively) generated semantically heterogeneous knowledge for open environments like the Semantic Web. In contrast to traditional approaches to knowledge assembling, knowledge sharing and ontology integration, which emphasize semantical consistency ...

In the last year, Brazil announced the voluntary commitment to reduce its greenhouse gas emissions from 36.1% to 38.9% by 2020 and, to this end, such a commitment requires cutting down 80% of the deforestation in the Amazon rainforest until that year. Much of the uncertainty on the role of forests for carbon emissions is due to the lack of reliable deforestation data. The Brazilian’s National I...

Based on our numerical heart and chest model with stochastically modifiable action potential duration (APD) parameters, the consequences of diminished subepicardial cell-to-cell coupling were studied on beat-to-beat repolarization heterogeneity. Pathological action potential durations and transmural gradient (TG) mean values (M) were assumed in the apical segment of the five-layer heart model, ...

Parasitism is a major biotic determinant of animal population dynamics and community structure. Temporal and spatial heterogeneity in parasitism is commonly observed in intermediate host populations. Understanding the causes of temporal and spatial variation in the recruitment of parasites is crucial if we are to manage host populations and animal communities effectively. Here, the temporal and...

This paper presents assumptions and identification results for eBay type auctions. These results are for private value auctions covering three major issues; censoring bias, auction heterogeneity and dynamic bidding. The first section of the paper presents two identification results for second price open call auctions with private values and unobserved participation (eBay type auctions). The sec...

This paper develops a new approach to the estimation of consumer demand models with unobserved heterogeneity subject to revealed preference inequality restrictions. Particular attention is given to nonseparable heterogeneity. The inequality restrictions are used to identify bounds on counterfactual demand. A nonparametric estimator for these bounds is developed and asymptotic properties are der...

This paper derives the analytics of seller and buyer participation in an auction hosting site, characterizes optimal hosting site pricing and investigates the nature of competition between two auction houses or hosting sites that are differentiated in the eyes of the bidders. The auction sites earn revenue by setting positive listing fees, trading off the increased revenue per seller from highe...
