U sing aggregate product search data from Amazon.com, we jointly estimate consumer information search and online demand for consumer durable goods. To estimate the demand and search primitives, we introduce an optimal sequential search process into a model of choice and treat the observed market-level product search data as aggregations of individual-level(More)
We describe online consumers' search behavior for differentiated durable goods using a data set that captures a detailed level of consumer search and attribute information for digital cameras. Consumers search extensively, engaging in 14 searches on average prior to purchase. Individual level search is confined to a small part of the attribute space. Early(More)
The authors propose a new method to visualize browsing behavior in so-called product search maps. Manufacturers can use these maps to understand how consumers search for competing products before choice, including how information acquisition and product search are organized along brands, product attributes, and price-related search strategies.

PURPOSE To evaluate the usefulness of infrared digital photography for determining scotopic pupil size by comparing infrared digital photography with a Colvard pupillometer (Oasis Medical). SETTING Department of Ophthalmology, Ajou University School of Medicine, Suwon, Korea. METHODS Scotopic pupil size in 50 eyes of 25 healthy individuals was measured(More)
In an attempt to present a new surgical technique for arthroscopic bony Bankart fixation, the authors developed the pulled sutures technique. In executing the new method, the authors first passed several non-absorbable sutures through labroligamentous tissue with displaced articular fragment by mimicking transglenoid suture technique. Aimed at achieving a(More)
PURPOSE To report the optical coherence tomography (OCT) findings of the firmly attached foveal area and to investigate the functional results and predictive values in correlation to the degree of firmness of the foveal adherence of the epiretinal membrane (ERM). METHODS We retrospectively reviewed the medical records regarding 167 eyes of 166 patients(More)
