This paper examines the relationship between Schumpeterian patterns of innovation and the generation of breakthrough inventions. Our data source for breakthrough inventions is the “R&D 100 awards” competition organized each year by the magazine Research & Development. Since 1963, this magazine has been awarding this prize to 100 most technologically significant new products available for sale or licensing in the year preceding the judgment. We use USPTO patent data to measure the relevant dimensions of the technological regime prevailing in each sector and, on this basis, we provide a characterization of each sector in terms of the Schumpeter Mark I/Schumpeter Mark II archetypes. Our main finding is that breakthrough inventions are more likely to emerge in ‘turbulent’ Schumpeter Mark I type of contexts.  相似文献

This study investigates how the effect of employee stock ownership on financial performance may hinge on the diverse cultural and societal contexts of European countries. Based on agency and national culture theories, we hypothesize that the positive relationship between employee stock ownership and return on assets (ROA) is stronger in those nations with lower uncertainty avoidance and higher social trust. Using a multisource, time‐lagged, large‐scale dataset of 1,741 firms from 21 countries in Europe, our multilevel, random coefficient modeling analysis found evidence for these hypotheses, suggesting that uncertainty avoidance and social trust serve as important contextual cues in predicting the linkage between employee stock ownership and financial performance. Our supplemental analysis with distinction between the managerial and nonmanagerial employee stock ownership further indicates managerial employee stock ownership has a direct positive effect on ROA. Although nonmanagerial employee stock ownership had a nonsignificant association with ROA, the relationship was positive and significant when uncertainty avoidance was low and social trust was high. This research contributes to the existing literature by illuminating some of the contextual influences altering the effectiveness of employee stock ownership. Our findings also offer practical suggestions for effectively using employee stock ownership.  相似文献

The establishment of the Economic and Monetary Union was expected to determine price convergence in the market of the European Union, leading to the equilibrium theorized by the law of one price. This article investigates prices convergence in the coffee market among European importers. Coffee is not only a tradable and traded good, but also one of the most valuable traded commodities. We account for different qualities of coffee in a hedonic regression model, which isolate and remove the effects of factors that might affect price dispersion. Adjusted import prices result to be significantly different between European Member States, and do not support the hypothesis of a deepening European market integration.  相似文献

The present study draws on the concepts of motives and heuristics to thoroughly understand consumers’ sustainable consumption behaviour in the context of personal care products. The mixed-methods approach combines real purchasing data with in-depth qualitative data to generate insights with a high external validity. In the first section of the study, quantitative analysis is applied to actual purchasing behaviour (n = 10,772,477) to identify market trends. Three main groupings, along with specific heuristic cues, are established. In the second step, a qualitative study (n = 21) provides deeper insights into consumers’ motives and decision-making processes. By synthesising the quantitative and qualitative research findings, a segmentation approach is developed. Relevant motives and values, and corresponding specific heuristic cues are identified for each consumer segment. Analysis suggests that consumers are motivated by self-interest and environmental motives, and that they use simple heuristic cues to make quick and satisfying purchasing decisions. Both retailers and manufacturers can leverage these insights to seize the opportunities of the developing market for sustainable personal care products.  相似文献

Strategic Partnerships in New Product Development: an Italian Case Study   总被引:6,自引:0,他引:6  
This article provides some revealing insights into what a leading Italian firm operating in markets where innovation is a focal point of competition has learned about partnering with suppliers in the new products development process. To succeed in a rapidly changing environment, the firm promoted and sustained tightly linked, integrated supplier relationships. This provided one key element of a shorter product cycle, led to better products, and increased the firm's ability to compete. Andrea Bonaccorsi and Andrea Lipparini explore why partnering is critical for new product success. Finally, they highlight the steps that should be taken to make this relationship a productive one.  相似文献

Indices for Working Land Conservation: Form Affects Function   总被引:2,自引:0,他引:2  
Using environmental indices (EIs) to rank applications for enrollment in conservation programs is becoming common practice. However, there is little guidance on how it should be done. The indices adopted by existing programs have often been linear, using weighted averages of environmental parameters without explicit consideration of whether they represent a reliable preference ordering on environmental states. Our article investigates society's weights for addressing multiple resource concerns and how functional forms of EIs can influence program outcomes. We propose a means by which preference weights are observed from policymaker actions. Weights for multiple resource concerns are determined and combined with biophysical crop simulation data to create an environmental index (EI) for crop rotations. This index is developed using alternative function forms to score conservation efforts on working cropland and to measure their effect on program outcomes.  相似文献

A simple note on herd behaviour   总被引:4,自引:0,他引:4  
In his ‘Simple model of herd behaviour’, (Banerjee A (1992) A simple model of herd behaviour. Q J Econ CVII:797–817) shows that—in a sequential game—if the first two players have chosen the same action, player 3 and all subsequent players will ignore his/her own information and start a herd, an irreversible one. In this paper, we analyse the role played by the tie-breaking assumptions in reaching the equilibrium. We show that: players’ strategies are parameter dependent—an incorrect herd may be reversed; a correct herd is irreversible.

We study reputational herding in financial markets in a laboratory experiment. In the spirit of Dasgupta and Prat [2008], career concerns are introduced in a sequential asset market where wages for investors are set by subjects in the role of employers. Employers can observe investment behavior, but not investors' ability types. Thereby, reputational incentives may arise endogenously. We find that a sizable fraction of investors follows an established trend even in a setting where there are no reputational incentives. In a setting where there are reputational concerns, they do not seem to create substantial herd behavior.  相似文献

Background: Sarcoidosis is a multi-system inflammatory disorder characterized by the presence of non-caseating granulomas in involved organs. Patients with sarcoidosis have a reduced quality-of-life and are at an increased risk for several comorbidities. Little is known about the direct and indirect cost of sarcoidosis following the initial diagnosis.

Aims: To provide an estimate of the healthcare resource utilization (HCRU) and costs borne by commercial payers for sarcoidosis patients in the US.

Methods: Patients with a first diagnosis of sarcoidosis between January 1, 1998 and March 31, 2015 (“index date”) were selected from a de-identified privately-insured administrative claims database. Sarcoidosis patients were required to have continuous health plan enrollment 12 months prior to and following their index dates. Propensity-score (1:1) matching of sarcoidosis patients with non-sarcoidosis controls was carried out based on a logistic regression of baseline characteristics. Burden of HCRU and work loss (disability days and medically-related absenteeism) were compared between the matched groups over the 12-month period following the index date (“outcome period”).

Results: A total of 7,119 sarcoidosis patients who met the selection criteria were matched with a control. Overall, commercial payers incurred $19,714 in mean total annual healthcare costs per sarcoidosis patient. The principle cost drivers were outpatient visits ($9,050 2015 USD, 46%) and inpatient admissions ($6,398, 32%). Relative to controls, sarcoidosis patients had $5,190 (36%) higher total healthcare costs ($19,714 vs $14,524; p?p?p?Background: Sarcoidosis is a multi-system inflammatory disorder characterized by the presence of non-caseating granulomas in involved organs.

Relative to controls, sarcoidosis patients had $5,190 (36%) higher total healthcare costs ($19,714 vs $14,524; p?<?0.001). Sarcoidosis patients also had significantly more work loss days (15.9 vs 11.3; p?<?0.001) and work loss costs ($3,288 vs $2,527; p?<?0.001) than matched controls. Sarcoidosis imposes an estimated total direct medical cost of $1.3–$8.7 billion to commercial payers, and an indirect cost of $0.2–$1.5 billion to commercial payers in work loss.

Conclusions: Sarcoidosis imposes a significant economic burden to payers in the first year following diagnosis.  相似文献

There is growing interest in Nova Scotia's Environmental Farm Plan (NS EFP) program among farmers and policy makers because of several reasons. First, effectiveness of standardized or uniform beneficial management practices in mitigating the negative environmental impacts from agriculture is limited by inherent heterogeneities in agricultural production systems. In addition, there is heightened interest in farmers generating ecological goods and services to society. This study investigates the determinants of participation in the NS EFP program. A discrete choice model of NS EFP participation was applied to a sample of 83 farmers (representing a 31% response rate). To increase relevance of the study to program administrators, the study also examined farmers’ use of various channels and sources of information on farm conservation practices. The most used sources of information on farm conservation practices include a mix of interpersonal sources and government agencies. Although online information (especially those available for free) appears to be gaining popularity in usage, overall, electronic and computer channels of information (especially radio and television) were used less compared with traditional channels of communicating farm conservation information (such as newsletters and agricultural magazines). Regression analysis suggests that farm characteristics (i.e., farm type, farm size, farm income) and farmer capacity variables (i.e., specialized training and knowledge from EFP program information sessions and workshops, and on-farm stewardship demonstrations) were significant determinants of environmental farm planning.  相似文献
