Caso Clínico ARP nº 26: Qual o seu diagnóstico?
Silva, João Santos; Alegrio, João; Pires, Verena; Donato, Henrique; Semedo, Luís Curvo; Marques, Cristina; Donato, PauloA 68-year-old woman with a history of arterial hypertension and Gilbert´s syndrome was referred to a Gastroenterology consultation due to adenomyomatosis of the gallbladder. Additionally, laboratory results reveal changes on liver tests and an abdominal computed tomography (CT) was initially performed. An incidentaloma on the second part of the duodenum was described (arrow). Then, the upper digestive endoscopy...

Testing competing models for non-negative data with many zeros
Silva, João Santos; Tenreyro, Silvana; Windmeijer, FrankIn economic applications it is often the case that the variate of interest is non-negative and its distribution has a mass-point at zero. Many regression strategies have been proposed to deal with data of this type but, although there has been a long debate in the literature on the appropriateness of different models, formal statistical tests to choose between the competing specifications are not often used in ...
Identification with averaged data and implications for hedonic regression studies
Silva, João Santos; Machado, JoséIn the estimation of models with averaged data, weighted least squares is often used and recommended as a way of improving the e¢ciency of the estimator. However, if the size of the di¤erent groups is not conditionally independent of the regressand, consistent estimation may not be possible at all. It is argued that in the case of some leading examples of averaged data regression, consistent estimation is possi...
Measuring the importance of the uniform nonsynchronization hypothesis
Dias, Daniel; Marques, Carlos Robalo; Silva, João SantosIn this paper we critically reappraise some measures of the importance of time- dependent price setting rules and propose an alternative way to gauge the signi - cance of this type of price setting behaviour. The merits of the proposed measure are highlighted in an application using micro-data. Our results suggest that a large proportion of price trajectories may be compatible with simple time-dependent price s...
Time or state dependent price setting rules? Evidence from portuguese micro data
Marques, Carlos R.; Dias, Daniel; Silva, João SantosIn this paper we analyse the ability of time and state dependent price setting rules to explain durations of price spells or the probability of changing prices.Our results suggest that simple time dependent models cannot be seen as providing a reasonable approximation to the data and that state dependent models are required to fully characterise the price setting behaviour of Portuguese firms. Inflation, the le...
