momentum traders in the housing Market Survey evidence and a search model
The American Economic Review, 2009Co-Authors: Monika Piazzesi, Martin SchneiderAbstract:This paper studies household beliefs dur ing the recent US housing boom. The first part presents evidence from the Michigan Survey of Consumers. To characterize the heterogeneity in households’ views about housing and the econ omy, we perform a cluster analysis on Survey responses at different stages of the boom. The estimation always finds a small cluster of house holds that believe it is a good time to buy a house because house prices will rise further. The size of this “momentum” cluster strongly increased toward the end of the boom. The second part of the paper provides a simple search model of the housing Market to show how a small number of optimistic investors can have a large effect on prices without buying a large share of the housing stock. The raw Survey data suggest that the housing boom had two distinct phases. During the early boom years 2002–2003, a large and increasing fraction of households believed that the time for buying a house was good. This fraction peaked at 85.2 percent in 2003:II. The most important reason—cited by up to 72 percent of house

momentum traders in the housing Market Survey evidence and a search model
National Bureau of Economic Research, 2009Co-Authors: Monika Piazzesi, Martin SchneiderAbstract:This paper studies household beliefs during the recent US housing boom. The first part presents evidence from the Michigan Survey of Consumers. To characterize the heterogeneity in households' views about housing and the economy, we perform a cluster analysis on Survey responses at different stages of the boom. The estimation always finds a small cluster of households who believe it is a good time to buy a house because house prices will rise further. The size of this "momentum" cluster doubled towards the end of the boom. The second part of the paper provides a simple search model of the housing Market to show how a small number of optimistic investors can have a large effect on prices without buying a large share of the housing stock.

A rapid Market Survey on the availability of car seats in Qatar: Implications for child passenger safety.
Qatar medical journal, 2019Co-Authors: Rafael Consunji, Shahnaz Malik, Hassan Al Thani, Katharine A. Allen, Amber Mehmood, Tooba Tariq, Adnan A. Hyder, Ruben PeraltaAbstract:Introduction: Despite the high income level in Arabian Gulf countries, people in the region need to improve their use of child restraint systems (CRSs) to reduce the incidence of preventable injuries to child automobile passengers. Anecdotal reports have attributed the resistance to using CRSs to the expense and unavailability of the systems, prompting car seat giveaway programs. Previous studies have not assessed the adoption of CRS. This study reports the results of a rapid Market Survey (RMS) to understand the availability, characteristics, and affordability of CRSs in Qatar and recommend future child restraint policies and legislation. Methods: The RMS identified all retail outlets that sell CRSs in Qatar and collected standard data on each restraint system: brand, model number, age/weight limits, compliance with standards, availability, and language of the owner's manual. A previously utilized metric for child safety devices was used to measure affordability. Results: The RMS showed a sufficient number (83) and variety (five types) of car seat models at 15 retail outlets, selling at a wide price range of $14-$1,399. All the car seats complied with the European standard. Only 2% showed a manufacturing or expiry date. A user manual was available for 71% of the seats and in different languages, but only 28% appeared in Arabic. The median CRS price was equivalent to the wages for less than one day of work. Conclusion: The RMS demonstrates the availability, variety, and affordability of CRSs in Qatar. Unavailability and expense cannot be cited as barriers to use CRS, and the Market is prepared for legislation requiring car seats for children in Qatar. Areas for improvement include requiring user manuals for all seats, especially in Arabic; requiring that all car seats comply with globally accepted safety standards, especially for expiry/manufacturing dates, given the harsh local climate; and encouraging further varieties of CRSs in the local Market.

Are there car seats in Qatar? Results and recommendations from a rapid Market Survey
Journal of Local and Global Health Science, 2015Co-Authors: Shahnaz Malik, Ruben Peralta, Kate Allen, Adnan Hyder, Hassan Al Thani, Rafael ConsunjiAbstract:Mortality for young children in motor vehicle crashes in Qatar was highest in those who were unrestrained1. Anecdotal reports have attributed low car seat use to their expense and unavailability prompting car seat giveaway programs, but an assessment of the local car seat Market has not been conducted previously. This study will report the results of a rapid Market Survey (RMS) to understand the availability, characteristics and the cost of child restraints and make recommendations for future child restraint policies and legislation in Qatar. This RMS was conducted as part of the Young Kids in Safe Seats Project funded by the Qatar Foundation. The Survey involved locating all retail outlets that sell child restraints in Qatar and collecting standard data on each restraint system: brand, model no. age/weight limits, compliance with standards, availability and language of owner's manual. The RMS showed a sufficient number and variety of car seat models [83] available at 19 retail outlets with a wide affordability range [$46 - $810]. All of the car seats complied with the European standard. Only 2% showed a date of manufacture or expiry. A user manual was available in only 71% of seats and in a variety of different languages, but only 36% in the native language of Arabic. This RMS demonstrates the availability and variety of child restraint systems in Qatar. Unavailability and expense cannot be cited as barriers to their use and the Market is prepared for legislation requiring car seats for children in Qatar. Areas for improvement include: requiring user manuals for all seats, especially in Arabic, that all car seats comply with globally accepted safety standards, especially expiry/manufacturing dates, given the harsh local climate, and encouraging more variety in the local Markets.

gluten detection in foods available in the united states a Market Survey
Food Chemistry, 2015Co-Authors: Girdhari M Sharma, Marion Pereira, Kristina M WilliamsAbstract:Abstract Many gluten-free (GF) food choices are now available in superMarkets. However, the unintentional presence of gluten in these foods poses a serious health risk to wheat-allergic and celiac patients. Different GF labelled foods (275) and non-GF labelled foods, without wheat/rye/barley on the ingredient label (186), were analysed for gluten content by two different enzyme linked immunosorbent assay (ELISA) kits. Considering the gluten threshold of 20 ppm, GF labelled foods had 98.9% GF labelling compliance with 1.1% (3 out of 275) of foods being mislabelled/misbranded. Among the non-GF labelled foods, 19.4% (36 out of 186) of foods had >20 ppm of gluten, as measured by at least one ELISA kit, of which 19 foods had >100 ppm of gluten. The presence of oats in non-GF labelled foods was strongly correlated with a positive ELISA result. Gluten was also found in a significant number of foods with gluten/wheat-related advisory warnings.

bacterial and viral pathogens in live oysters 2007 united states Market Survey
Applied and Environmental Microbiology, 2010Co-Authors: Angelo Depaola, Jessica L Jones, Jacquelina Woods, William Burkhardt, Kevin R Calci, Jeffrey A Krantz, John C Bowers, Kuppuswamy N Kasturi, Robin H Byars, Emily JacobsAbstract:Two samples of Market oysters, primarily from retail establishments, were collected twice each month in each of nine states during 2007. Samples were shipped refrigerated overnight to five U.S. Food and Drug Administration laboratories on a rotating basis and analyzed by most probable number (MPN) for total and pathogenic Vibrio parahaemolyticus and V. vulnificus numbers and for the presence of toxigenic V. cholerae, Salmonella spp., norovirus (NoV), and hepatitis A virus (HAV). Levels of indicator organisms, including fecal coliforms (MPN), Escherichia coli (MPN), male-specific bacteriophage, and aerobic plate counts, were also determined. V. parahaemolyticus and V. vulnificus levels were distributed seasonally and geographically by harvest region and were similar to levels observed in a previous study conducted in 1998-1999. Levels of pathogenic V. parahaemolyticus were typically several logs lower than total V. parahaemolyticus levels regardless of season or region. Pathogenic V. parahaemolyticus levels in the Gulf and Mid-Atlantic regions were about two logs greater than the levels observed in the Pacific and North Atlantic regions. Pathogens generally associated with fecal pollution were detected sporadically or not at all (toxigenic V. cholerae, 0%; Salmonella, 1.5%; NoV, 3.9%; HAV, 4.4%). While seasonal prevalences of NoV and HAV were generally greater in oysters harvested from December to March, the low detection frequency obscured any apparent seasonal effects. Overall, there was no relationship between the levels of indicator microorganisms and the presence of enteric viruses. These data provide a baseline that can be used to further validate risk assessment predictions, determine the effectiveness of new control measures, and compare the level of protection provided by the U.S. shellfish sanitation system to those in other countries.
