Theoretical studies have shown that under unorthodox assumptions on preferences and production technologies, collateral constraints can act as a powerful amplification and propagation mechanism of exogenous shocks. We investigate whether or not this result holds under more standard assumptions. We find that collateral constraints typically generate small output amplification. Large amplification is obtained as a “knife‐edge” type of result.

Older adult pedestrian injuries in the United States: causes and contributing circumstances

As the US population ages, more older adults will face transportation and mobility challenges. This study examines the characteristics and contributing circumstances of nonfatal older adult pedestrian injuries. Data were obtained from the National Electronic Injury Surveillance System-All Injury Programme (NEISS-AIP) for the years 2001 through 2006. Cases included persons aged 65 years and older who were nonfatally injured on a public roadway. The results indicated that on average, an estimated 52,482 older adults were treated in emergency departments each year for nonfatal pedestrian injuries. Falling and being hit by a motor vehicle were the leading mechanisms of injury, resulting in 77.5% and 15.0% of older adult pedestrian injuries, respectively. More than 9000 older pedestrian fall-related injuries each year involved a kerb. It is concluded that the growth in the older adult population could add to the overall burden of these nonfatal pedestrian injuries. Making transportation and mobility improvements, including environmental modifications, is important for preventing these injuries.     

When do structural holes in employees' networks improve their radical creativity? A moderated mediation model

Previous research has found a relationship between structural holes of knowledge networks, tie strength of knowledge networks, and creativity. Our study extends these findings by proposing that characteristics of R&D employees' team knowledge networks influence their acquired diversified knowledge from the team, which is critical to creativity. Our results based on 558 members of 92 R&D teams demonstrated that, in order to benefit from their broker position in acquiring diversified knowledge, R&D employees should maintain their tie strength toward the team members with whom they are connected.     

麦肯锡全球调查创新与商业化

随着企业开始重新关注增长,创新冉一次成为了优先要务:在最近进行的麦肯锡全球调查中1,84%的高管称创新对于其企业的增长战略极为重要或非常重要.调查结果还显示,与危机前相比,企业用于产生出色创意并将这些创意转变为产品或服务的方法变化不大,而这并非因为高管们认为这些方法非常有效.此外,发现合适的人才、鼓励协作与承担风险,以及从头到尾组织创新流程等挑战也依然如故,这一点值得大家注意.事实上,过去几年的调查显示,成功创新的核心障碍一直没有变化,而企业在克服这些障碍方面也没有什么进展.     

The role of taxonomic and goal‐derived product categorization in,within, and across category judgments

Consumers can face two types of judgment and choice situations: They may be considering products that are classified in a single product category, or products that may belong to several different product categories. This article compares these within‐ and across‐category judgments on the basis of the distinction between taxonomic and goal‐derived categorization. The first study examines how products that belong to taxonomic and goal‐derived categories are represented in memory. The findings support the view that taxonomic categories differ from goal‐derived categories in terms of the ease with which the features shared between members of the category are accessible and the type of features that are used to represent the members. In turn, these differences influence consumer beliefs, judgments, and choice sets when consumers make within‐ and across‐category product comparisons. A second study examines how consumers' familiarity with consumption situations influences the construction of choice sets. Results indicate that as familiarity with consumption situations increases, consumers construct more narrowly defined, within‐category choice sets, whereas in less‐familiar situations consumers construct broader, across‐category choice sets. The implication of these findings on marketing action is discussed. © 2001 John Wiley & Sons, Inc.     

The purchase of components: Functional areas of influence

The Webster and Wind model of organizational buyer behavior enjoys considerable popularity. However, not all of its constructs and relationships among constructs have been validated by empirical research. The purpose of this study was to provide empirical evidence concerning the relationships between three of the model's critical constructs: buying center membership, purchase situation, and purchase phase. The relationships studied were variations in the perceived relative influence of different functional areas (e.g., production, marketing, purchasing, etc.) across three purchase situations and four purchase phases. The results of the study clearly indicate that the functional areas are generally perceived to have varying amounts of influence across both the purchase situation and purchase phase. These results have specific implications for developing effective industrial marketing strategies.     

What Does a High School Diploma Get You? Employment, Race, and the Transition to Adulthood

We compare the employment of African American and white youth as they transition to adulthood from age 18 to 22, focusing on high school graduates and high school dropouts who did not attend college. Using OLS and hazard models, we analyze the relative employment rates, and employment consistency, stability, and timing, controlling for a number of factors including family income, academic aptitude, prior work experience, and neighborhood poverty. We find white high school graduates work significantly more than all other youth on most measures; African American high school graduates work as much and sometimes less than white high school dropouts; African American dropouts work significantly less than all other youth. Findings further suggest that the improved labor market participation associated with a high school diploma is higher over time for African Americans than for white youth.     

Food Regime Analysis in a Post‐Neoliberal Era: Argentina and the Expansion of Transgenic Soybeans

This paper uses the food regime literature to analyse the political and economic relations promoting the expansion of soybeans in Argentina following the post‐neoliberal turn in the early 2000s. Continuities of the agrarian expansion from the neoliberal to post‐neoliberal model highlight the state's role in supporting a neoliberal food regime. Neoregulation in the post‐neoliberal agenda continues to favour increased production of transgenic food over ecological and human‐health considerations. Moreover, the emergence of new corporate and transnational actors has contributed to a new form of corporate‐agrarian governance premised on biotechnology. First, a food regime lens is used to describe the expansion of transgenic soybeans in Argentina, followed by an analysis of planning documents to show the state's position in reproducing neoliberal discourses and policies favouring the expansion of agriculture. The conclusion discusses the utility of food regime analysis for explaining the new forms of agricultural governance in Argentina.     

Sales promotions for preorder products: The role of time‐of‐release

Preorder offers are increasingly common for many types of products and services. Sales promotions, such as price discounts and free gifts, are frequently used to raise offer attractiveness and elicit a stronger sales response. Through a series of experiments, we show that a preorder promotion's effectiveness depends on whether it matches the construal level associated with timing of the featured product's release. When a match occurs, it increases consumers’ positive affect leading to higher purchase intention directly or by raising the perceived certainty of new product quality. In addition, we find interesting differences related to promotion type. Specifically, we show that a larger discount promotes low‐level construals, which leads to stronger purchase intentions only when the product is scheduled for near‐future release. Since a gift may elicit either high‐ or low‐level construals, a premium offer of higher perceived value leads to stronger purchase intentions regardless of release timing.
