Certain manuals and computer programs mistakenly identify the mean with the constant in Box-Jenkins time series models. In this paper, it will be shown that (a) the mean and the constant have different values in autoregressive models, and (b) they have an algebraic and graphical relationship. 相似文献

We examine the incentives for upstream firms to consolidate horizontally and the impact of this process on industry performance, when there are downstream entry barriers and firms negotiate bilaterally. In the short run, consumers are not worse off with upstream mergers, since consolidation only results in a redistribution of industry rents. In the long run, consumers are better off after upstream mergers, since they induce more entry into that segment. When social welfare is evaluated, a limit on upstream consolidation may prevent excessive entry; but upstream entry can be sometimes insufficient, if the retailers' intrinsic bargaining power is excessive. 相似文献

A formal model of productivity growth and technical progress is presented. The model takes into account embodied and disembodied technical progress as explanatory variables. The slowdown in productivity growth for the Spanish economy after 1972 is explained for 92% by the decline in the rate of growth of technical progress originated from domestic R&D and technology imports. 相似文献

Although credit risk is an important factor that financial institutions must cope with, the determinants of bank problem loans have been little studied. Using panel data, we compare the determinants of problem loans of Spanish commercial and savings banks in the period 1985–1997, taking into account both macroeconomic and individual bank level variables. The GDP growth rate, firms, and family indebtedness, rapid past credit or branch expansion, inefficiency, portfolio composition, size, net interest margin, capital ratio, and market power are variables that explain credit risk. However, there are significant differences between commercial and savings banks, which confirm the relevance of the institutional form in the management of credit risk. Our findings raise important bank supervisory policy issues: the use of bank level variables as early warning indicators, the advantages of bank mergers from different regions, and the role of banking competition and ownership in determining credit risk. 相似文献

The objective of this paper is to evaluate the impact on bank credit exposures to small- and medium-sized Spanish firms of the current proposal for reform of the 1988 Capital Accord using information from the Spanish Credit Register. Capital requirements for exposures to those firms, according to the various revisions of the proposed capital reform (from the January 2001 consultative document to the April 2003 one), are calculated to analyze whether the existing pattern of bank financing of small- and medium-sized firms might be altered. Finally, the incentives for individual banks to adopt the advanced internal ratings-based approach proposed by Basel II are evaluated. 相似文献

Investment costs for fish processing plants are hereby presented along with a detailed analysis of different types of processes in relation to economies of scale.The cost-capacity factor for fish industry is estimated as 0.84, except for fish meal plants where the cost-capacity factor is 0.61.It is also discussed how technology, capacity and location in developed and developing countries can affect investment costs for fish processing plants, while cost-capacity factors remain unchanged.The concept of minimum limit for industrial capacity is included. Investment costs for minimum size plants or plants below minimum size are even greater than what would correspond to the correlation line. This is due to the need to incorporate one or more oversized pieces of equipment. 相似文献

This study analyzes how managers of retail travel agencies perceive the antecedents and consequences of adopting e-business in their supplier relationships. A comprehensive model integrating its antecedents and relational effects is developed and empirically tested using SEM. The study surveyed 101 travel agents in Spain. Research findings indicate that customer pressure has a strong influence on e-communication practices. E-communication with the travel agency's supplier and the pressure exerted by the sector are the main antecedents for e-procurement. Effects of e-business on relational quality are contradictory. E-procurement influences negatively on trust. Conversely, e-communication has a positive impact on trust, thus having a favorable impact on perceived reciprocity and travel agent's commitment to its supplier. Main findings indicate that the use of the Internet is largely driven by normative pressures, and this coercive power has a detrimental impact on trust. To avoid such negative consequences, perceived reciprocity is a prerequisite for committed supplier relationships. 相似文献

Although NPD collaboration with external partners has become the next generation in NPD practice, the discussion concerning how to organize collaboration so as to obtain better results is far from over. Since communication is the most important element in successful interfirm exchange, this study focuses on the impact of collaborative communication and its facets—frequency, formality, reciprocal feedback, and rationality—on NPD collaboration results. In order to explain how collaborative communication can best be managed to enhance NPD collaboration results, this research combines the relational and resource‐based views, proposing the existence of two routes of influence: the direct resource‐based route and the indirect relational route mediated by trust. Using a sample of 207 NPD collaboration projects of innovative firms, empirical findings indicate that reciprocal feedback–rationality and frequency play an important role in product quality and adherence to budget and schedule, respectively, even without trust. Moreover, the trust between partners substantially reinforces the positive influence of reciprocal feedback–rationality on NPD collaboration results and makes the effect of formality significant. Therefore, the two alternative routes are confirmed as important paths to new product success, which provides relevant managerial implications. 相似文献
