Speculative behavior in vacant land development: evidence for real options in Malaysia

The development of vacant land may be seen from a real options perspective—owners of vacant land have the incentive to delay developing the land and keep their options open (keep the lands undeveloped) if they believe that future development will yield higher value. We investigate whether there is speculative behavior with regard to vacant land development in Malaysia. Using samples of 254 vacant plots of lands and 3,681 houses in Selangor, Malaysia, we find that the option premium for vacant lands ranges from 8% to 20% across all areas in Selangor. We posit that the higher option premium for vacant lands is the result of a higher level of speculation by landowners. We also find that, while the option value increases, the intrinsic value reduces the market price of the vacant land. Our findings are indicative of speculative behavior by the owners of vacant land in Malaysia

Are patients aware of potential risks of weight reduction surgery? An internet based survey

Background/Aim: Obesity has become a global health care problem. In Saudi Arabia, up to 75% of adults are reportedly overweight. Morbid obesity has been associated with an increased risk of many comorbidities and mortality. Bariatric surgery is currently considered the most effective treatment option for morbid obesity. However, there are many concerns regarding the short and long-term complications of weight reduction surgery. It is unclear whether the general population is adequately aware of these risks. Therefore, we aimed to assess awareness of the general population of bariatric surgery complications. Although effective, bariatric surgery has been associated with many acute complications, reported in a range of 0.3% to 8% of operations. Patients and Methods: We performed a cross-sectional study between July and August of 2017 in Jeddah, Saudi Arabia. We used a 26-item, Arabic, electronically distributed questionnaire, to examine public awareness of the acute complications of bariatric surgery. Hypothesis testing was used to examine associations. Results: In total, 624 questionnaires were completed electronically. Mean age of participants was 25 (±13.2) and 66% were females. Of the surveyed population, 64% reported being aware of acute complications of bariatric surgery. Participants who had previously undergone a bariatric operation had a higher degree of awareness when compared to those who had not undergone a bariatric operation before (80.4% vs. 61.3%, P < 0.001). Females had higher awareness compared to males (70.8% vs. 52.1%, P < 0.001). Awareness of complications was not statistically different when stratified by level of education (P = 0.131) but occupation predicted awareness (P = 0.007). Conclusion: Two-thirds of the general population appears to be aware of the potential acute complications associated with bariatric surgery. Furthermore, awareness seems to be higher in females, individuals who had previously undergone weight reduction surgery, and health care workers
