The prevalence of overweight and obesity has reached epidemic proportions in the United States. Nearly two-thirds of adult Americans are overweight or obese, and the prevalence of overweight among American children between the ages of 6 and 19 has tripled during the past 20 years, from 5 percent in 1980 to 15 percent in 2000. United States Surgeon General Richard Carmona calls obesity America's single biggest health problem. The evidence for the relationship between obesity and several chronic illnesses is becoming increasingly clear. Although changing behavior is difficult, growing recognition of the health impact and costs associated with overweight and obesity, combined with increased knowledge regarding effective prevention and treatment interventions, provide momentum for addressing this epidemic. However, reversing current trends will require a multifaceted public health approach.
Myriad genetic, social, and environmental factors contribute to overweight and obesity. The rapid increase in their rates in the United States, however, suggest that social and environmental influences have played the major role in contributing to the nation’s overweight and obesity problem. In particular, recent social and environmental trends that have likely affected weight levels include: decreased physical activity in daily lives, increased use of commercial food products, larger commercial food portions, and increasing prevalence of community design that does not support physical activity. Furthermore, a relationship between obesity and low socioeconomic status has long been documented.
The impact of information on security prices is a fundamental building block for the modern finance theory. Literature has well established that public information arrivals may cause volatility of stock prices, and that private information about asset values may be conveyed by signed trading volume or net order flows. However, how public and private information are eventually impounded into stock prices remains a subject of considerable debate in any types of financial markets.
The focus of this study is on how public and private information are incorporated in stock prices via order submissions and executions in a pure order-driven market. Specifically, we address three research questions: Firstly, are order flows informative on stock returns? Secondly, do public information arrivals increase or decrease the informativeness of order flows on stock returns? Thirdly, how does the intensity of public information arrivals affect the relation between price volatility, trading volume and the shape of the order book?
The patterns in which individuals interact have important consequences. One notable phenomenon is social learning, which occurs when asymmetrically informed individuals observe the choices of others before making their own choices. This process can lead to information cascades in which the ability to learn from others ceases quickly, implying little information aggregation. However, casual empiricism suggests that such inefficiency is unlikely: many people making similar decisions over time are unlikely to be continually wrong.
