This research examined the extent to which different promotional frames increased perceptions of deal value. Price discounts dominate the sales promotions employed by marketers. The framing literature suggests discounts have robust positive effects on consumer perceptions of deal value. However, the current research showed that negative quality inferences moderated discount framing effects and undermined deal value, particularly when no assurance of product quality was provided. Every-day-low-price offers were also vulnerable to negative quality inferences, while free gift frames maintained quality perceptions and increased deal value. Product trial acted to further magnify promotional framing effects, according to a confirmation bias. These findings were consistent with an attribute framing mechanism.  相似文献

We examine the performances of several popular Lévy jump models and some of the most sophisticated affine jump‐diffusion models in capturing the joint dynamics of stock and option prices. We develop efficient Markov chain Monte Carlo methods for estimating parameters and latent volatility/jump variables of the Lévy jump models using stock and option prices. We show that models with infinite‐activity Lévy jumps in returns significantly outperform affine jump‐diffusion models with compound Poisson jumps in returns and volatility in capturing both the physical and risk‐neutral dynamics of the S&P 500 index. We also find that the variance gamma model of Madan, Carr, and Chang with stochastic volatility has the best performance among all the models we consider.  相似文献

Technological Progress versus Efficiency Gain in Manufacturing Sectors   总被引:1,自引:0,他引:1  
This study decomposes the nonparametric Malmquist productivity index for 36 Korean manufacturing sectors into two components: technological change and technical efficiency change. The empirical results show that while each sector displays quite different growth patterns, productivity growth is dominated by technological change. Technological change is found to have a negative correlation with efficiency change. Secondary regression performed in this study identifies the relationship between productivity growth measures and several key policy variables, such as effective protection rate, market concentration, and so forth. The productivity estimates are compared with those of the conventional Törnqvist productivity index.  相似文献

Through the use of business-to-business electronic commerce (B2B e-commerce), leading companies are transforming interorganizational transaction processing, trading, and collaboration into a competitive advantage. The research empirically examines several models with B2B e-commerce overall use as the dependent variable and innovation characteristics, context, channel factors, and organizational structure as the predictor variables. The results demonstrate that compatibility with existing systems, cooperative norms with customers, lateral integration within a firm, technocratic specialization, and decentralization of information technology decisions facilitate B2B e-commerce overall use. In addition, large firms are more likely than small firms to have greater levels of B2B e-commerce and firms are more likely to use B2B e-commerce with customers that use recommendations rather than threats to encourage e-commerce use.  相似文献

R&D collaboration facilitates the pooling of complementary skills, learning from the partner as well as the sharing of risks and costs. Research therefore stresses the positive relationship between collaborative R&D and innovation performance. Fewer studies address the potential drawbacks of collaborative R&D. Collaborative R&D comes at the cost of coordination and monitoring, requires knowledge disclosure, and involves the risk of opportunistic behavior by the partners. Thus, while for lower collaboration intensities the net gains can be high, costs may start to outweigh benefits if firms perform a higher share of their innovation projects collaboratively. For a sample of 2735 firms located in Germany and active in a broad range of manufacturing and service sectors, this study finds that increasing the share of collaborative R&D projects in total R&D projects is associated with a higher probability of product innovation and with a higher market success of new products. While this confirms previous findings on the gains for innovation performance, the results also show that collaboration has decreasing and even negative returns on product innovation if its intensity increases above a certain threshold. Thus, the relationship between collaboration intensity and innovation follows an inverted‐U shape and, on average, costs start to outweigh benefits if a firm pursues more than about two‐thirds of its R&D projects in collaboration. This result is robust to conditioning market success to the introduction of new products and to accounting for the selection into collaborating. This threshold is, however, contingent on firm characteristics. Smaller and younger as well as resource‐constrained firms benefit from relatively higher collaboration intensities. For firms with higher collaboration complexities in terms of different partners and different stages of the R&D process at which collaboration takes place, returns start to decrease already at lower collaboration intensities.  相似文献

Summary. This paper generalizes Segerstrom [5], a dynamic general equilibrium model of endogenous growth through quality improvements in which innovation and imitation are modeled as the outcomes of research and development (R&D) races. Specific factors introduced into the technologies of both R&D activities achieve diminishing returns to scale in R&D. The comparative-static results of subsidies to R&D activities depend on the degree of diminishing returns to scale in R&D. When there is (is not) a sufficient degree of diminishing returns to R&D, a subsidy to innovative activity increases (decreases) innovative activity.

Buyers' perspectives of buyer-seller relationship development   总被引:1,自引:0,他引:1  
Long-term buyer-seller relationships have been a focus of research for several years. The present study draws on interaction/network theory to test a model examining the interaction mechanisms and relationship characteristics of buyer-seller relationships during four progressive phases of relationship development. Data from 174 members of the Institute for Supply Management offer empirical support for the associations proposed in the model, as well as some surprising results. One of the most useful findings of the research is that the patterns of these associations vary as buyer-seller relationships progress through the four phases of relationship development. Specifically: in the awareness phase, joint problem solving increases buyer uncertainty; in the exploration phase, communication quality and joint problem solving increase relationship-specific investments; and in the expansion phase, joint problem solving increases relationship-specific investments and severe conflict resolution increases buyer uncertainty. Seller reputation moderates many of these relationships. The major conclusion of the research is that buyers and sellers should recognize that while information exchange and conflict resolution are important aspects of buyer-seller relationships, their use may not always lead to the desired relationship characteristics. Managerial implications of these findings and further research ideas are presented.  相似文献

This paper presents a satellite account where households are treated as production units. It extends previous work that treats consumer durables as investment and that values nonmarket household production activities such as cooking, cleaning, and childcare. Services from consumer durables and government capital related to household production are also valued. In constructing the updated accounts, this paper incorporates new time use data from the American Time Use Survey (ATUS) and the harmonized time use data from the Multinational Time Use Study (MTUS). This paper also discusses and incorporates recommendations made by the U.S. National Academies panel on nonmarket accounts.  相似文献

Using the five available waves of the Wage Structure Survey data, this study employs quantile decomposition to investigate the existence of a glass ceiling among Korean professionals. The decomposition results for all professional workers show an inverse U-shape, which implies no evidence of a glass ceiling. However, we find a monotonically increasing pattern for arts and culture professionals, indicating strong evidence of a glass ceiling on their labour market. This result implies that, as the wage quantile moves from lower to higher levels, female professionals in arts and culture jobs face significant barriers to career advancement. This analysis supports the recent assertion of UNESCO that gender equality in culture is not immune to inequalities and discrimination.  相似文献

We study the problem of assigning a set of objects to a set of agents, when each agent receives one object and has strict preferences over the objects. In the absence of monetary transfers, we focus on the probabilistic rules, which take the ordinal preferences as input. We characterize the serial rule, proposed by Bogomolnaia and Moulin (2001) [2]: it is the only rule satisfying sd efficiency, sd no-envy, and bounded invariance. A special representation of feasible assignment matrices by means of consumption processes is the key to the simple and intuitive proof of our main result.  相似文献
