Unaffected Strangers Affect Contributions

Several recent experimental studies have confirmed that social sanctioning can enforce cooperation in public good situations. These studies consider situations where the participants, who have monetary interest in the outcome of the public good game, inflict social sanctioning. The present experimental study, however, considers behavioral effects of social sanctioning from observers with no monetary interest in the outcome of the public good game. The experiment has two treatment effects. First, each participant’s identity and contribution to the public good is revealed to the observers. Second, we introduce information likely to affect participants’ expectations regarding the observers’ approval or disapproval of contributions to the public good. The data provides some evidence that indirect social sanctioning from these monetarily unaffected observers can increase voluntary contributions to public goods, provided that the participants have reason to believe that the observers have themselves contributed substantially in a similar situation. However, the effect on cooperation is not as strong as effects found in previous studies where participants themselves, and not only monetarily unaffected observers, are able to inflict social sanctioning.cooperation, public good, social approval, social norms

Effects of inspections on plants' regulatory and environmental performance - evidence from Norwegian manufacturing industries

Abstract: The present paper investigates effects of regulatory inspections on compliance and emissions of energy intensive manufacturing plants in Norway. The regression analysis shows that increased probability of inspection reduces the probability of violation. This is in line with previous studies, and may appear as an encouraging evaluation of the practiced regulatory enforcement policy. However, the direct environmental impact of the enforcement policy is more dubious: Regression analyses reveal a positive relationship between the probability of an inspection and emissions. It appears puzzeling that increased probability of inspection can yield both reduced probability of violation and higher emissions. The possibility that such a puzzle evolves from incentives inherent in the practiced regulatory policy is discussed.

Workload, staff composition, and sickness absence: findings from employees in child care centers

Persistently, high workload may raise sickness absence with associated costs to firms and society. We proxy workload by the number of adults per child in Norwegian child care centers and find that more educated teachers per child are associated with lower sickness absence. However, more assistants with low or no higher education per child are associated with higher sickness absence, suggesting that observed variation in sickness absence at the center level may be driven by differences in staff composition rather than workload. The importance of the educational composition of employees on sickness absence is supported by findings from fixed-effects models and a fuzzy regression discontinuity design relying on variation from municipal elections.acceptedVersio

Electronic monitoring and recidivism. Quasi-experimental evidence from Norway

The replacement of custodial with non-custodial sanctions holds the potential to reduce recidivism as well as other costs associated with imprisonment. However, the causal impacts on recidivism of non-custodial sanctions in general, and electronic monitoring (EM) programs in particular, remain unclear. We estimate the effect of EM on recidivism by exploiting an EM program that was gradually introduced in Norwegian counties from 2008, using difference-in-differences and instrumental variable designs. Results show that introducing EM reduced 2-year recidivism rates by about 10 percent, which corresponds to about 19 percent for those actually serving on EM. We find no effects on recidivism intensity or severity. Subsample analyses show that the effect estimates are strongest among offenders without previous imprisonment or recent unemployment spells, and although between-groups differences are statistically non-significant, this suggest that avoiding prison stigma and maintaining workplace relations can be important to reduce recidivism and promote desistance. The reliability of our results is somewhat challenged by unstable pre-implementation trends and signs that more people are convicted to EM-qualifying sentences when EM is introduced

Technological changes in the pulp and paper industry and the role of uniform versus selective environmental policy

Abstract: Although environmental regulations may imply a cost increase on firm's conventional input factors, such regulations could stimulate the incentives to improve factor productivity. Productivity measures including indicators capturing environmental improvements may also show higher or lower progress than productivity measures ignoring environmental aspects. We apply a Malmquist productivity index approach on micro data for the Norwegian pulp and paper industry, and find that the overall productivity growth accounting for changes in emissions of COD to water is higher than the growth in the productivity measure including conventional inputs only. We find the opposite result when including emissions of acids and climate gases to air. This is probably due to environmental regulations with opposing effects on different emissions. A decomposition of the Malmquist index into a technical efficiency change factor and a technical change component shows that the frontier technology has changed, while the average distance to the frontier has increased.

Gut microbiota is associated with dietary intake and metabolic markers in healthy individuals

Background: Metabolic diseases have been related to gut microbiota, and new knowledge indicates that diet impacts host metabolism through the gut microbiota. Identifying specific gut bacteria associated with both diet and metabolic risk markers may be a potential strategy for future dietary disease prevention. However, studies investigating the association between the gut microbiota, diet, and metabolic markers in healthy indi-viduals are scarce.Objective: We explored the relationship between a panel of gut bacteria, dietary intake, and metabolic and anthropometric markers in healthy adults.Design: Forty-nine volunteers were included in this cross-sectional study. Measures of glucose, serum tri-glyceride, total cholesterol, hemoglobin A1c (HbA1c), blood pressure (BP), and body mass index (BMI) were collected after an overnight fast, in addition to fecal samples for gut microbiota analyzes using a targeted approach with a panel of 48 bacterial DNA probes and assessment of dietary intake by a Food Frequency Questionnaire (FFQ). Correlations between gut bacteria, dietary intake, and metabolic and anthropometric markers were assessed by Pearson’s correlation. Gut bacteria varying according to dietary intake and metabolic markers were assessed by a linear regression model and adjusted for age, sex, and BMI.Results: Of the 48 gut bacteria measured, 24 and 16 bacteria correlated significantly with dietary intake and metabolic and/or anthropometric markers, respectively. Gut bacteria including Alistipes, Lactobacillus spp., and Bacteroides stercoris differed according to the intake of the food components, fiber, sodium, saturated fatty acids, and dietary indices, and metabolic markers (BP and total cholesterol) after adjustments. Notably, Bacteroides stercoris correlated positively with the intake of fiber, grain products, and vegetables, and higher Bacteroides stercoris abundance was associated with higher adherence to Healthy Nordic Food Index (HNFI) and lower diastolic BP after adjustment.Conclusion: Our findings highlight the relationship between the gut microbiota, diet, and metabolic mark-ers in healthy individuals. Further investigations are needed to address whether these findings are causally linked and whether targeting these gut bacteria can prevent metabolic diseases.publishedVersio

Substitution of TAG oil with diacylglycerol oil in food items improves the predicted 10 years cardiovascular risk score in healthy, overweight subjects

Dietary fat is normally in TAG form, but diacylglycerol (DAG) is a natural component of edible oils. Studies have shown that consumption of DAG results in metabolic characteristics that are distinct from those of TAG, which may be beneficial in preventing and managing obesity. The objective of the present study was to investigate if food items in which part of the TAG oil is replaced with DAG oil combined with high α-linolenic acid (ALA) content would influence metabolic markers. A 12-week double-blinded randomised controlled parallel-design study was conducted. The participants (n 23) were healthy, overweight men and women, aged 37–67 years, BMI 27–35 kg/m2, with waist circumference >94 cm (men) and >88 cm (women). The two groups received 20 g margarine, 11 g mayonnaise and 12 g oil per d, containing either high ALA and sn-1,3-DAG or high ALA and TAG. Substitution of TAG oil with DAG oil in food items for 12 weeks led to an improvement of the predicted 10 years cardiovascular risk score in overweight subjects by non-significantly improving markers of health such as total body fat percentage, trunk fat mass, alanine aminotransferase, systolic blood pressure, γ-glutamyl transferase, alkaline phosphatase and total fat-free mass. This may suggest that replacing TAG oil with DAG oil in healthy, overweight individuals may have beneficial metabolic effects

Replacing saturated fatty acids with polyunsaturated fatty acids increases the abundance of Lachnospiraceae and is associated with reduced total cholesterol levels-a randomized controlled trial in healthy individuals

Improving dietary fat quality strongly affects serum cholesterol levels and hence the risk of cardiovascular diseases (CVDs). Recent studies have identified dietary fat as a potential modulator of the gut microbiota, a central regulator of host metabolism including lipid metabolism. We have previously shown a significant reduction in total cholesterol levels after replacing saturated fatty acids (SFAs) with polyunsaturated fatty acids (PUFAs). The aim of the present study was to investigate the effect of dietary fat quality on gut microbiota, short-chain fatty acids (SCFAs), and bile acids in healthy individuals. In addition, to investigate how changes in gut microbiota correlate with blood lipids, bile acids, and fatty acids.publishedVersio

Impact of COVID-19 on pregnancy-related healthcare utilisation: a prospective nationwide registry study.

OBJECTIVE: To assess the impact of COVID-19 on pregnancy-related healthcare utilisation and differences across social groups. DESIGN: Nationwide longitudinal prospective registry-based study. SETTING: Norway. PARTICIPANTS: Female residents aged 15-50 years (n=1 244 560). MAIN OUTCOME MEASURES: Pregnancy-related inpatient, outpatient and primary care healthcare utilisation before the COVID-19 pandemic (prepandemic: 1 January to 11 March 2020), during the initial lockdown (first wave: 12 March to 3 April 2020), during the summer months of low restrictions (summer period: 4 April to 31 August 2020) and during the second wave to the end of the year (second wave: 1 September to 31 December 2020). Rates were compared with the same time periods in 2019. RESULTS: There were 130 924 inpatient specialist care admissions, 266 015 outpatient specialist care consultations and 2 309 047 primary care consultations with pregnancy-related diagnostic codes during 2019 and 2020. After adjusting for time trends and cofactors, inpatient admissions were reduced by 9% (adjusted incidence rate ratio (aIRR)=0.91, 95% CI 0.87 to 0.95), outpatient consultations by 17% (aIRR=0.83, 95% CI 0.71 to 0.86) and primary care consultations by 10% (aIRR=0.90, 95% CI 0.89 to 0.91) during the first wave. Inpatient care remained 3%-4% below prepandemic levels throughout 2020. Reductions according to education, income and immigrant background were also observed. Notably, women born in Asia, Africa or Latin America had a greater reduction in inpatient (aIRR=0.87, 95% CI 0.77 to 0.97) and outpatient (aIRR 0.90, 95% CI 0.86 to 0.95) care during the first wave, compared with Norwegian-born women. We also observed that women with low education had a greater reduction in inpatient care during summer period (aIRR=0.88, 95% CI 0.83 to 0.92), compared with women with high educational attainment. CONCLUSION: Following the introduction of COVID-19 mitigation measures in Norway in March 2020, there were substantial reductions in pregnancy-related healthcare utilisation, especially during the initial lockdown and among women with an immigrant background
