U 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)
Sequential Search with Refinement: Model and Application with Click-stream Data We propose a structural model of consumer sequential search under uncertainty about attribute levels of products. Our identification of the search model relies on exclusion restriction variables that separate consumer utility and search cost. Because such exclusion restrictions(More)
BACKGROUND The short-term results of modified Brostrom procedures (MBP) have been satisfactory. However, the long-term results of anatomical reconstruction have been less frequently reported. We report on our long-term results in our patient group. MATERIALS AND METHODS Thirty patients with chronic ankle instability who were treated using the MBP without(More)
The purpose of this study was to evaluate the surgical results of modified tension band wiring using two cortical screws for the treatment of fifth metatarsal stress fractures. Forty-two patients with Torg’s type I and II fifth metatarsal stress fractures treated using the modified tension band wiring technique from 2005 to 2008 were evaluated(More)
BACKGROUND There have been diverse results, even in the same Torg type classification, in cases with fifth metatarsal stress fracture. HYPOTHESIS The "plantar gap" is correlated with the time for bone union and complications. It might be used for a prognostic factor. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Seventy-five cases with a(More)
BACKGROUND Only 2 articles related to the recently developed Mobility Total Ankle System (Johnson & Johnson Medical/DePuy International, Leeds, UK) have been published to date. The purpose of this study was to determine the perioperative complications associated with the Mobility Total Ankle System and whether a learning curve exists for this system. (More)
BACKGROUND Malalignment following total ankle arthroplasty (TAA) has been reported in 4% to 45% of patients. However, all reports to date have been related to coronal deformity. This study compared sagittal malalignment between the Mobility and Hintegra total ankle systems and assessed the positional stability of the implant components over time. METHODS(More)
PURPOSE The objective of this retrospective study was to evaluate the long-term follow-up results of neurectomy clinical outcomes and complications in the treatment of Morton's neuroma. MATERIALS AND METHODS A total of 19 patients (19 different feet) were treated for Morton's neuroma by excision of the interdigital nerve at our institute between May 1997(More)
