Development projects in the oil industry often have cost overruns. Through analysis of data from Norwegian development projects in the petroleum industry, this paper investigates the common effect of business cycle developments on cost overruns. Lack of capacity and expertise in a tight supplier market yield cost inflation and difficulties in managing projects. Unlike previous analyses of cost overruns, we analyse projects over a long time period to capture the cyclical effects. We document a statistically significant positive relationship between oil price developments and cost overruns, with shocks or surprises to the oil price during the project implementation having a larger impact on cost overruns than the oil price level itself. Cost overrun ultimately leads to reduced competitiveness for the industry, and we discuss consequences and policy implications for business and society of these cost overruns.

Introduction: Several studies indicate that the number of individuals experiencing depression symptoms is growing. There is a prevailing consensus in the literature that while depression is represented among both genders, it is consistently reported that females are more exposed to depression compared to males both in frequency and severity. Studies suggest that as many as 15-20 percent of adolescents in Norway exhibit depression or depression like symptoms. Furthermore, several studies indicate that the number of individuals experiencing depression symptoms is growing. There is a prevailing consensus in the literature that while depression is represented among both genders, it is consistently reported that females are more exposed to depression compared to males both in frequency and severity. Methods: All data utilized in this study were extracted from the Norwegian Ungdata survey conducted in 2014 among adolescents in Norway. The sample consists of 46,374 observations. Conclusions: The finding of significant differences in prevalence of self-diagnosed depression symptoms among Norwegian adolescents, showed females are more exposed. Furthermore, as hypothesized, there is a strong and significant relation between hope and depression, where hope is proxied through expectations regarding the individuals' future education, happiness and wealth. Based on these findings, we apply hope as an instrument for addressing depression symptoms. Results from this analysis indicate that males are significantly less optimistic for the future.
Introduction: Usage of over-the-counter (OTC) analgesic has increased among Norwegian adolescents since 2001. It has been noted that females tend to have a higher usage compared to males. In this paper we explore this gender difference. Data: Our dataset consists of 284,674 from Norwegian adolescents attending junior high school and high school between 2014 and 2017. Methods: The econometric approach consists of applying ordered logistic regressions with usage of OTC analgesics as the dependent variable and a dichotomous gender variable as the independent variable. Control variables include variables such as frequency of physical and mental health problems and other sociodemographic variables. Results: Gender, physical and mental health problems and various sociodemographic variables are found to have a significant effect on usage of OTC analgesics. Females are predicted to use significantly more analgesics. A large proportion of the gender difference evaporates when controlling for various other determinants. Conclusion: A considerable part of the observed gender difference in OTC analgesic usage can be traced back to differences in frequency and severity of physical and mental health problems. Part of the gender difference in usage, however remains unexplained.
We examine drivers of cost overruns in Norwegian development projects in the oil and gas sector. The multivariate longitudinal econometric analysis employs a unique and detailed dataset consisting of 80 different projects between 2000 and 2015. Among the significant results, we find that the unexpected change in economic activity has a positive effect on the overruns; there is a considerable positive momentum in the transitional cost overruns; more experienced operators tend to incur less overruns; finally, that the size of the investment of the projects has a positive impact on the overruns. Further, we find evidence that the current economic activity matters to an extent, but it is the unexpected change in activity that is the pivotal factor.
