We examine the causal impact of financial development (FD) on top income shares for a panel of 14 OECD countries—five Anglo‐Saxon countries, eight continental European countries, and Japan—over a 110‐year period. In our main General Method of Moments estimates, we find that a 1‐percentage‐point change in FD increases the top 1% income share by 0.2%. In distribution terms, a 1‐SD incr=ease in FD increases the top 1% income share by around 0.4 of an SD. The effects are robust to various measures of top income shares and FD and alternative estimation techniques, including nonparametric estimation. FD is typically viewed in positive terms in that it makes it easier to access credit and facilitates economic growth. Our results are important because they contribute to understanding of the potential negative effects of FD. 相似文献

Despite the widespread adoption of e-procurement by firms in recent years, academic research examining the mechanisms through which e-procurement applications lead to performance has been scarce. Anecdotal evidence points to numerous situations where companies have failed to harness the potential of e-procurement. In this paper, we argue that online purchase volume and mix flexibilities facilitated by these applications play a significant role in the ability of firms to benefit from e-procurement. We examine this tenet from both an economic as well as a social perspective. We propose that increased online purchase volume flexibility as well as online purchase mix flexibility can be facilitated by two mechanisms – supplier customization as explained by transaction costs perspective, and information sharing between supply chain partners using a social exchange theoretical perspective. The increased purchase volume and mix flexibility in turn leads to better performance along the dimensions of cost, quality, and delivery. We present and test a nuanced perspective where we argue that (i) the effect of supplier customization on both purchase volume and mix flexibilities will be moderated by the frequency of transactions conducted online, and (ii) the effect of information sharing on both purchase volume and mix flexibilities will be moderated by trust in the supplier. We estimate our research model using survey data collected from 130 purchasing and procurement managers. We find strong support for our proposed research model with results indicating that purchase volume and mix flexibilities play a vital mediating role in impacting e-procurement performance. Theoretical and practical implications of the findings are discussed. 相似文献

Short-term financing in a cash-constrained supply chain 总被引:4,自引:0,他引:4

In this paper we consider a two-level supply chain with a single retailer and a manufacturer, where both the firms are facing financial constraints and can not produce/order their optimal quantity. Our work shows that a lender who finances the manufacturer has a motivation to finance the retailer as well. Motivated by this, we investigate lender's problem of financing both the firms by making a joint decision on the loan amount and comparing it with the case when lender makes independent decision on loan amount for both the firms. Our numerical study indicates that if one of the firms in the supply chain has sufficiently low cash, joint decision (we refer to it as supply chain financing) may be better not only for the lender but for the retailer and manufacturer as well. 相似文献

Following the success of endogenous growth theory, recent empirical examinations of the demography–economic growth construct established that components of demographic change can provide meaningful and clear insights into the direction and impact of demographic variation in economic growth. While theoretical justification and empirical support to the claim cannot be denied, confusions seem to have arisen whether an empirical growth construct will only be limited to demographic dynamics or the model can entertain other non-demographic variables. In a leading research, Kelley and Schmidt (1995, 2001) provided seemingly ambiguous evidence that addition of non-demographic variables can add explanatory power to the growth regression. While subsequent empirical growth models have largely followed the convention as in KS, some important considerations like the stochastic effects of demographic system on economic growth seem to be missing. This paper attempts to address the concerns by suggesting a long-memory demographic system and embedding stochastic demographic characteristics in a standard Solow–Swan model, which also forms the basis of convergence pattern. We empirically show that significant stochastic shocks exist in the demographic components which could have contributed to the growth volatility across nations. We suggest that empirical growth models should account for stochastic demographic characteristics to enable economic policy makers with correct information about the current and future state of evolution of the demography–economic system. 相似文献

In R&;D organizations of high tech firms, multiple R&;D projects are executed concurrently and timeliness of project completion - i.e., developing the right products at the right times - is a matter of serious concern. Given that the priority of R&;D projects and the interdependencies between the projects in a high tech firm change dynamically, high tech R&;D project management is a complex and challenging endeavor. To improve the understanding and management of high tech R&;D projects, this paper reports the findings of a field study where we, first, develop and empirically estimate a model that relates project priority over time with the generative mechanisms of market pull and technical challenge associated with R&;D projects. Next, we develop and demonstrate the application of a process model within which the time-varying project priority model is embedded. The process model makes it possible to allocate fixed resources among competing projects with time-varying interdependencies, thereby improving the timeliness of project completion. This research was conducted in collaboration with a major U.S. high tech firm. The corporate R&;D center of the firm served as the research setting for the field study. We present an application of the process model to delineate the evolution of the R&;D organization with the merger of its (technology driven) parent firm with another (market driven) high tech manufacturing firm. The application of the process model generates theoretical insights that are used to develop testable propositions. Implications of the study findings and directions for future research are discussed. 相似文献

We study the assignment model where a collection of indivisible goods are sold to a set of buyers who want to buy at most one good. We characterize the extreme and interior points of the set of Walrasian equilibrium price vectors for this model. Our characterizations are in terms of demand sets of buyers. Using these characterizations, we also give a unique characterization of the minimum and the maximum Walrasian equilibrium price vectors. Also, necessary and sufficient conditions are given under which the interior of the set of Walrasian equilibrium price vectors is non-empty. Several of the results are derived by interpreting Walrasian equilibrium price vectors as potential functions of an appropriate directed graph. 相似文献

A multiphase study involving 1,285 respondents was conducted to answer an important yet overlooked question: for a job requiring frequent informal communication with superiors, should an organization focus more on selecting employees with higher trait‐like willingness to communicate or on providing an environment where the flow of communication is easy and aided? We found support for the latter. Further, we observed that subordinates alter their communication behaviors based on the perception of superior's power, politics in the organization, and their own political skills. The study contributes to a better understanding of how situational variables affect subordinate‐superior upward communication. Implications of the study are also discussed. © 2016 Wiley Periodicals, Inc. 相似文献

This paper surveys the evidence on the effectiveness of monetary transmission in low-income countries. It is hard to come away from this review with much confidence in the strength of monetary transmission in such countries. We distinguish between the “facts on the ground” and “methodological deficiencies” interpretations of the absence of evidence for strong monetary transmission. We suspect that “facts on the ground” are an important part of the story. If this conjecture is correct, the stabilization challenge in developing countries is acute indeed, and identifying the means of enhancing the effectiveness of monetary policy in such countries is an important challenge. 相似文献
