We explore the role and relevance of resource scarcity in product innovation. The literature tends to assume that the development of new products requires resource sufficiency for the process to be conducted systematically. But we are also taught that necessity is the mother of invention and that resource scarcity may be a trigger of innovation in adverse contexts. In this discussion, we organize the literature on product innovation in resource‐poor contexts in three streams. The paper contributes to a finer‐grained understanding of the role of scarcity in product innovation and suggests that creative approaches to scarcity may contribute to knowledge enrichment of product innovation theory and practice. 相似文献

We describe the preferred taxation regime in a small economy with uncertain institutional quality. We obtain that a preferential taxation regime in which taxes can be matched to the mobility of the tax base may be worse off than a non-preferential taxation regime in which taxes are constant across bases with distinct mobility. Since the small economy takes foreign taxes as given, our result is not driven by a downward pressure on revenues caused by unconstrained tax competition. It is instead related to the ability of a non-preferential taxation regime to credibly convey information about the institutional quality of the small economy. We present some empirical evidence which corroborates our results. 相似文献

In monetary models where M0 has no social costs and a positive demand for cash and deposits is taken as a primitive, we show
that the compensating variation in endowment is the exact general equilibrium measure of welfare costs of perfectly anticipated
inflation. As a consequence, we show that a good approximation to the welfare costs of inflation is given by the area under
the compensated demand for M0, a result that brings us back to Bailey (J Polit Econ 64:93–110, 1956). The estimated welfare
costs of inflation are bounded at less than a quarter of a percent of the GDP for the U.S. economy.

Rauch (1999) introduced a product classification scheme that has since been widely used to empirically identify differentiated goods. Using firm-level data on export unit values, we provide direct evidence that this classification is well suited for capturing quality differentiation. 相似文献

Entrepreneurship, and individuals’ predisposition toward entrepreneurial activities in particular, i.e. Individual Entrepreneurial Orientation (IEO), has been gaining increasing relevance in academia and management practice alike. Understanding IEO is a critical element not only for its promotion, but for better and more informed managerial and investor decision making as well. As such, this study proposes a new framework for understanding and measuring IEO based on the integrated use of cognitive mapping and the interactive multiple criteria decision making (TODIM) method. We present the steps for building such a framework, as well as a practical application of these steps. The results are promising: the methodology applied allowed a large number of determinants of IEO and their relationships to be mapped; and, subsequently, ranked and weighted for the creation of an IEO measurement tool. The implications of the resulting framework for theory and practice, its limitations and possibilities for further research are also discussed. 相似文献

Managing interdependencies in supplier networks 总被引:1,自引:0,他引:1
Building and managing a supplier base has been referred to in the literature as a key aspect of supplier management. Scholars have proposed a number of models aimed at enhancing the effectiveness of supplier network management, mainly based on a portfolio approach. In the IMP tradition of research, those models are often criticized as they ignore the interdependencies between the different existing dyadic relationships of a focal buyer company and its suppliers. Such interdependencies are the main focus of this paper, which has four objectives: (1) To analyze the types of relationships linking suppliers, (2) to understand the factors and dynamics underlying the creation and management of these relationships (3) to uncover existing links between buyer-supplier and supplier-supplier relationships, and (4) to clarify how different configurations of supplier relationship interactions impact on the performance of the actors involved. The paper discusses two empirical case studies, using the supplier networks of two focal buyer companies. We find that supplier interdependencies are mainly a by-product of the buyer-supplier dyads. Furthermore, the nature and dynamics of these dyads are a strong determinant of the scope and frequency of supplier connections and the corresponding effects on performance. 相似文献

During the recent sovereign debt crisis, the European Banking Authority conducted two stress tests on European banks in order to gauge their capital needs, core Tier-1 ratios and ratios of resilience to adverse shocks. We assess the informational content of the disclosure of the stress test outcomes. We conclude that the stress tests conveyed new information and that the outcomes were not anticipated by the stock market but were partially anticipated by the credit default swap (CDS) market. However, while the stock market reacted to the disclosure of the stress test outcomes, in the CDS market there is some evidence of a ‘reverse’ reaction. Moreover, the publication of the outcomes of the stress tests had a stronger impact on the stock prices of riskier financial institutions. A similar pattern is evident in the CDS market, albeit narrowed to one of the stress tests and amid the financial institutions with higher perceived credit risk. 相似文献

This paper investigates the time series of realized correlations between global industries and the world market over the 1979–2008 period. The behavior of industry correlations is characterized by long-term swings, with a period of historically low correlations in the late 1990s. The Telecommunications and the Financials industries show a positive secular trend. Global industry correlations move countercyclically. Furthermore, there is evidence that industry correlations are higher for market downside moves than for upside moves. 相似文献
