This article complements the structural New-Keynesian macro framework with a no-arbitrage term structure model. Whereas our methodology is general, we focus on an extended macro-model with an unobservable time-varying markup and stochastic risk aversion. Term structure information helps to identify the dynamics of the observed and unobserved variables and(More)

Motivated by recent innovations in service delivery such as ride-sharing services and work-from-home call centers, we study capacity management when workers self-schedule. The service provider seeks to maximize its profit (revenue from served customers minus capacity costs) when it controls capacity only indirectly. Agents choose when to work based on the(More)
One of the major differences between markets that follow a " sharing economy " paradigm and traditional two-sided markets is that, in the sharing economy, the supply side includes individual nonprofessional decision makers, in contrast to firms and professional agents. Using a data set of prices and availability of listings on Airbnb, we find that there(More)
BACKGROUND The relation between early respiratory syncytial virus (RSV) infection and later emergence of episodes of wheezing/asthma remains a subject of debate. We carried out a systematic review of studies of the association between RSV infection in the first 36 months of life and the subsequent development of asthma/bronchial hyperreactivity. METHODS A(More)

The objective of the study was to identify the probability of death and its predictive factors in a cohort of successfully treated TB patients. METHODS A population-based retrospective longitudinal study was performed in Barcelona,(More)
The objective of the study was to examine the factors associated with unidentified tuberculosis (TB) index cases (1987-2007) and to describe outbreaks (2000-2007) of childhood TB cases in Barcelona, Spain. Contact tracing seems to be fundamental in index case identification, but improvement could be made among older children and cases of extrapulmonary TB(More)
Honeybees (Apis mellifera) have remarkable visual learning and discrimination abilities that extend beyond learning simple colours, shapes or patterns. They can discriminate landscape scenes, types of flowers, and even human faces. This suggests that in spite of their small brain, honeybees have a highly developed capacity for processing complex visual(More)

Low income countries and deprived areas, within big cities in developed countries, present the highest TB incidences and TB mortality rates. These are the settings(More)
