Aims: To obtain estimates of the relative treatment effects between insulin degludec/liraglutide (IDegLira) and insulin glargine U100/lixisenatide (iGlarLixi) in patients with type 2 diabetes mellitus (T2DM) uncontrolled on basal insulin therapy.Materials and methods: Data from phase 3 trials providing evidence for estimating the relative efficacy and safety of IDegLira vs iGlarLixi in patients uncontrolled on basal insulin-only regimens were used in this analysis. Outcomes of interest were changes in HbA1c, body weight and insulin dose, and rate ratio of hypoglycemia. The indirect comparison of the reported trial findings followed the principles of Bucher et al.Results: IDegLira was estimated to provide a 0.44 [95% CI?=?0.17–0.71] %-point reduction in HbA1c compared with iGlarLixi. Body weight was reduced by 1.42 [95% CI?=?0.35–2.50] kg with IDegLira compared with iGlarLixi. Insulin dose was comparable between the two interventions. The rate of severe or blood glucose-confirmed (self-measured plasma glucose [SMPG]?≤?3.1?mmol/L) hypoglycemia with IDegLira was approximately half that of iGlarLixi (rate ratio?=?0.51 [95% CI?=?0.29–0.90]). However, using the American Diabetes Association definition of documented symptomatic hypoglycemia (SMPG ≤3.9?mmol/L) the rate was comparable between the two treatments (rate ratio?=?1.07 [95% CI?=?0.90–1.28]).Limitations: The assumptions made in the indirect comparison and differences between the included trials in baseline HbA1c levels, previous use of sulfonylureas, definitions of hypoglycemia, presence or absence of run-in period, the different duration of the trials, and the cross-over design of one of the trials.Conclusions: The results of this indirect treatment comparison demonstrate that, among patients with T2DM uncontrolled on basal insulin, treatment with IDegLira results in a greater reduction of HbA1c and a greater reduction in body weight compared with iGlarLixi at similar insulin doses. 相似文献

This paper empirically measures the potential spillover effects of big-box retail entry on the productivity of incumbent retailers in the entry regions, and investigates whether the effects differ depending on the size of the new establishment relative to the size of the local market. The results indicate that big-box entry increases the productivity of incumbent stores in two of three rural entry regions where the IKEA is large relative to the local retail market, while no productivity spillover effects could be found in the case of the urban IKEA entry in Gothenburg. 相似文献

A difference/system generalized method of moments (GMM) model that imposes time-constant coefficients is common in empirical studies using panel data. However, a rejection by the Sargan–Hansen test is sometimes a serious concern for researchers. We highlight the fact that the Sargan–Hansen test for GMM estimators applied to panel data is a joint test of valid orthogonality conditions and coefficient stability over time. A possible reason for a rejection is therefore that the slope coefficients vary over time. One solution is to estimate an empirical model in which the coefficients are time specific. We apply this solution to the system GMM estimator of simple nondynamic Cobb–Douglas production functions for a selection of Swedish industries and find that relaxing the assumption of constant slope coefficients results in more satisfactory outcomes of the Sargan–Hansen test. 相似文献

An important feature of emissions trading is how emissions permits are allocated. The choice between an auction and free allocation
should not influence firms’ production choices nor consumer prices according to economic theory. However, many parties expect
the method of allocation to affect product prices. This paper describes an experimental investigation into price determination
under a cap-and-trade program with different allocation methods. Participants initially display diverse pricing strategies.
However, given a simple economic setting in which earnings depend on behavior, we find that subjects learn to consider the
opportunity cost of permits and overall behavior moves toward the economic prediction. 相似文献

Workplace bullying is a severe problem in contemporary working life, affecting up to 15 per cent of employees. Among the detrimental outcomes of bullying, it is even postulated as a major risk factor for exclusion from work. In support of this claim, the current study demonstrates that exposure to bullying behaviour predicts an increase in both levels of job insecurity and intention to leave over a 6‐month time lag, among a random sample of North Sea workers (n = 734). The findings suggest that bullied employees are insecure about the permanence and content of their job, and they may be at risk of turnover and exclusion from working life. It is recommended that these outcomes are taken into consideration when incidences of workplace bullying are addressed. 相似文献

Surveys are based on predetermined questions (PDQs), used in hypothesis testing. To validate surveys, an open-ended question (OEQs), probing for additional factors, is sometimes added. This approach could become more efficient by combining PDQs with OEQs in hybrid surveys. This study surveyed Japanese consumers on seafood quality (n?=?200). It started with three OEQs, asking participants to list the most important factors when evaluating packed mackerel fillets, before they assessed 26 PDQs on importance of different quality dimensions for the same products. The OEQs were grouped based on the PDQs and the answers were counted. The PDQs were rated on 7-point importance scales. The real-life relevance of PDQs was challenged based on the frequency counts of OEQs. The result revealed that the color, overall freshness, and price issues are the most important factors consumers consider in real life. The use of hybrid surveys led to increased validity of this study. 相似文献

We analyse the social interaction effects in sick‐leave behaviour in the workplace, using high‐quality Norwegian matched employer–employee data with detailed individual information on sick leaves during the 2004–2006 period. We find that social interaction effects in sick‐leave behaviour in the workplace do exist, and that the effects are noticeable in size. The strong relationship between the sick‐leave rates among colleagues is not solely the result of contagious diseases, nor is it caused by improved informational quality or by the increased workload for the non‐absent workers. Evidence supports the existence of reciprocal worker behaviour that is unrelated to joint leisure‐seeking activities. 相似文献

In many countries, sickness absence financed by generous insurance benefits is an important concern in the policy debate. There are strong variations in absence behavior among local geographical areas. Such variations are difficult to explain in terms of observable socioeconomic factors. In this paper, we investigate whether such variations are related to group effects in the form of social interaction among individuals within neighborhoods. Well‐known methodological problems arise when trying to answer this question. A special feature of our efforts to deal with these problems is that we adopt several alternative approaches to identify group effects. Our study is based on a rich set of Swedish panel data, and we find indications of group effects in each of our approaches. 相似文献

We examine how firms’ productivity level, measured by the total factor productivity (TFP), is affected by their use of academic workers. A panel dataset of Norwegian manufacturing firms is used. Firms’ production level is shown to be negatively affected by their share of academic workers, but we find no clear relationship between this share and the TFP. If we account for the fact that there is an interaction between the share of academic workers and the capital stock, we find that this share has a non‐significant effect on the production level. 相似文献
