State Trading and Tariff Rate Quotas: The Case of Korea's Rice Imports

This paper analyzes the effects of trade liberalization of tariff‐rate quotas under import “state trading enterprises” (STEs) in agriculture. An analytical framework is provided to determine the importance of which instrument is binding under competition (the in‐quota or out‐of‐quota tariff or the quota) and under the initial STE equilibrium. It also depends on whether or not the STE controls both the domestic market prices and owns/controls the import quota (and whether it is obligated to fill the quota or not). An empirical example of the rice STE in South Korea has simulations showing that an increase in imports can be achieved through a moderate expansion of the quota or a decrease in the out‐of‐quota tariff to the level where it becomes binding. However, a significant level of quota expansion induces the STE to switch to the autarky solution and social welfare declines.     

Combining biodiversity modeling with political and economic development scenarios for 25 EU countries

In the EURURALIS project, a chain of models was used to predict the changes in sustainable development indicators for European human well-being, ecology and economy issues, for four alternative scenarios of the future socio-economic development. This paper describes the biodiversity analysis of the project. Models based on general relationships between environmental factors and biodiversity loss were combined with socio-economic, land-use and environmental models to derive data that were integrated into an interactive tool for policy makers. The biodiversity analysis takes into account the effects of land-use change, climate change, fragmentation by major roads, area of unfragmented patches, nitrogen deposition, forestry and disturbance. Results show that biodiversity is projected to decrease between now and 2030 in most countries for all scenarios, indicating that it is unlikely that the EU will be able to fulfill its commitment to stop biodiversity loss by 2010. This is mainly due to urbanization and increase in stress factors, and outweighs the area increase of nature arising from land abandonment. Merits, limitations and uncertainties of this approach to biodiversity assessment are discussed.     

Thinking critically about critical thinking: Assessing critical thinking of business students using multiple measures

Critical thinking is a skill that potential employers expect all graduates to possess. Hence, most business management programs consider critical thinking as an important student learning goal. Unfortunately, there is ambiguity about how to best assess critical thinking, both as a skill and a learning outcome. The authors empirically demonstrate how they measure the critical thinking ability of their students in different settings, and how their critical thinking ability improves as they progress through the business program.

Information in generalized method of moments estimation and entropy-based moment selection

In this paper, we make five contributions to the literature on information and entropy in generalized method of moments (GMM) estimation. First, we introduce the concept of the long run canonical correlations (LRCCs) between the true score vector and the moment function f(_vt,_θ0)$f(v_t,{\theta }_0)$ and show that they provide a metric for the information contained in the population moment condition E[f(_vt,_θ0)]=0$\mathrm{E}[f(v_t,{\theta }_0)]=0$. Second, we show that the entropy of the limiting distribution of the GMM estimator can be written in terms of these LRCCs. Third, motivated by the above results, we introduce an information criterion based on this entropy that can be used as a basis for moment selection. Fourth, we introduce the concept of nearly redundant moment conditions and use it to explore the connection between redundancy and weak identification. Fifth, we analyse the behaviour of the aforementioned entropy-based moment selection method in two scenarios of interest; these scenarios are: (i) nonlinear dynamic models where the parameter vector is identified by all the combinations of moment conditions considered; (ii) linear static models where the parameter vector may be weakly identified for some of the combinations considered. The first of these contributions rests on a generalized information equality that is proved in the paper, and may be of interest in its own right.     

Pflegst Du schon oder dokumentierst Du noch?

Die vernetzte Pflegeplanung – Medikamentenblatt, ?rztliche Verordnung, der Basis-Status, die Status-Planungs-B?gen, das Ressourcen-F?higkeiten-Blatt – an Formularen ist in der Pflege kein Mangel. Doch immer neue Formulare machen aus einem ursprünglich guten Dokumentationssystem oftmals eine Loseblatt-Sammlung. Im Rahmen eines Projektes in der station?ren Altenpflege versuchte man, Doppeldokumentationen auf ein Minimum zu reduzieren und den Verlauf der Anamnese auf einen Blick zu erm?glichen.     

Revisiting Tversky's Trail—How Money Makes a Subtle Difference in Similarity Effect Experiments

Recent findings in research on context effects indicate that, as opposed to choices under hypothetical settings, compromise effects are significantly attenuated in binding settings that include real payments for products. The present investigation examines to what extent this finding applies to yet another context effect, namely the similarity effect (SE). The SE stipulates that, compared with initial shares of two options A and B in a binary choice set, the introduction of an option C that is dissimilar to B but similar to A will hurt the latter more than the nonadjacent option B. The conducted online survey examines the SE in unforced choices of experienced consumers between real brands across three consumer good categories. The results confirm that the SE is evidently reduced under real payment conditions, hence confirming the hypothesis that the applied choice setting moderates the efficacy of the composition of choice sets.     

Rewarding customers who keep a product: How reinforcement affects customers' product return decision in online retailing

A lenient product return policy represents the status quo of current return management practice in online retailing because it increases customers' order tendency. However, at the same time, many customers tend to return products under this policy, which incurs considerable costs for retailers. The present research introduces a keep reward (i.e., providing incentives to keep a product) as a new promotion strategy to improve the conventional lenient policy. Drawing on operant conditioning, the authors propose and test the reinforcing effect of a keep reward on customers' keep decision, compared to the conventional lenient policy. Results of a qualitative pilot study suggest that a keep reward is generally feasible in online retailing practice, especially in the low‐ to mid‐price segment and with rewards that are linked to future purchases. Two experimental studies verify the positive effect of a keep reward. Study 1 shows that it substantially increases keep intention compared to a conventional lenient policy. Study 2 shows that the effect on keep intention is moderated by customers' online shopping frequency, and this moderating effect is mediated by repurchase intention. In particular, the keep reward is most effective among frequent shoppers because they are more inclined to repurchase and thus, benefit from the reward. In summary, both studies support the keep reward as a valuable add‐on to the conventional lenient policy because order intention remains comparably high, while keep intention is higher. Theoretical implications and recommendations for online retailers on how to implement a keep reward in different industries are discussed.
