The probability capturing all individuals in the population is hardly ever one. Unless recapture probabilities are high, consistently similar and show no bias towards any particular sex, age or size-group, this can lead to incorrect inferences of demographic parameters (ref). Mark-recapture models are designed to handle such data. When individuals are uniquely marked, the recapture probability ...

We present a capture-recapture modeling approach to the estimation of survival probability of dependent chicks when only the attending adult bird is marked. The model requires that the bird's nest is found prior to hatching and that the number of eggs that hatch are counted. Subsequent data are sightings of the marked adult and a count of chicks with the adult. The model allows for imperfect de...

Mark-and-Recapture is a methodology from Population Biology to estimate the number of a species without counting every individual. This is done by multiple samplings of the species using traps and discounting the instances that were caught repeated. In this paper we show that this methodology is applicable for citation analysis as it is also not feasible to count all the relevant publications o...

With heterogenous firms, inter-national trade is predicted to increase aggregate productivity through a selection effect. The same theoretical insight applies to intra-national trade between sub-national economies. In this paper, we attempt at quantifying the impact of firm selection attributable to both international and intra-national trade. To do so, we structurally estimate and simulate a m...

Innovation, mark-ups and the degree of trade openness vary substantially across sectors. This paper builds a multi-sector endogenous growth model to study the in‡uence of asymmetric trade liberalisation and sectoral di¤erences in the degree of product market competition on the e¤ect that trade has on R&D investments at a …rm level. I …nd that di¤erences in the degree of competition generate lar...

The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...
