We present a model of capital accumulation and technology adoption in a vintage-capital framework. The model is an infinite-horizon/infinite-dimensional optimal control model: the firm employs a continuum of technologies (a continuum of heterogeneous capital goods). Capital goods are technology specific, their technology is related to vintage and technology progress. The entrepreneur maximizes the profits obtained by employing a continuum of technologies under the assumption of constant returns to scale and bearing adjustment costs for gross investments. The diffusion of a new technology is established by allowing the entrepreneur to invest in vintage capital goods. 相似文献

In this paper, the authors test whether loan-loss reserve announcements by individual commercial banks can have contagion
effects on the banking industry. It is found that increased loan-loss reserves related to LDC debt do not have an effect on
other banks. However, increased loan-loss reserves related to bad real estate loans elicited a negative share price response
at other banks. The signal from a loss reserve adjustment is dependent on the reason for the adjustment. While LDC debt problems
were restricted to money center banks and were well publicized, real estate loan problems can be contagious throughout the
industry. Consequently, signals of real estate loan problems at some banks can cause a reduced valuation of other banks. 相似文献

The slow-down of economic growth in European countries in recent years raises important economic policyissues. Most economic observers consider that the reasons for the slow-down are structural and are to be found in rigidities on the markets of primary factors or lack of technological innovative capabilities. Input–Output analysis can provide valuable insights into the nature of the phenomenon, and could help to design structural policies in order to foster economic growth. 相似文献

This article proposes a bivariate lattice model for evaluating equity-linked policies embedding a surrender option when the underlying equity dynamics is described by a geometric Brownian motion with stochastic interest rate. The main advantage of the model stays in that the original processes for the reference fund and the interest rate are directly discretized by means of lattice approximations, without resorting to any additional transformation. Then, the arising lattices are combined in order to establish a bivariate tree where equity-linked policy premiums are computed by discounting the policy payoff over the lattice branches, and allowing early exercise at each premium payment date to model the surrender decision. 相似文献

This study analyzes differences existing between new and established agri-entrepreneurs as well as differences in relation to their counterparts in non-agricultural ventures. This study uses the resource-based view and institutional economics as conceptual frameworks and focuses on the analysis of the resources and capabilities; entrepreneurial orientation (risk-taking, proactiveness and innovativeness); and legitimation affecting the entrepreneurial process. The literature points out that the specific characteristics of the sector (strong family links and institutional support) can condition the entrepreneurship process. Thus, hypotheses are developed to test these relationships. We use random effects models to test our hypotheses with the Global Entrepreneurship Monitor (GEM) for 20 European countries. Results show that agri-entrepreneurs have weaker entrepreneurial capabilities than other sectors. However, new entrants into the agricultural sector are not less entrepreneurial in relation to other sectors. On the other hand, established agri-entrepreneurs are less proactive than other sectors. Results suggest that new entrants into agriculture are more entrepreneurially oriented than established ones. Our study contributes to the entrepreneurship literature by contextualizing the entrepreneurship process and providing valuable insights for policy-makers to enhance farmers’ entrepreneurial skills and entrepreneurial orientation. 相似文献

The objective of this paper is to study empirically the relationship between export orientation and firms’ environmental performance from different perspectives of trade theory. On the one hand, productivity heterogeneity is analysed within the new trade‐theoretical framework. The approach followed is to determine firm‐level productivity components, including an environmental productivity indicator (as a performance measure) and taking as reference the Spanish food industry. On the other hand, from the traditional comparative advantage perspective, this study also develops an export performance model to evaluate the effect of technology, environmental variables and factor endowment on exporting. The results show greater environmental productivity and corporate efficiency for export‐oriented firms. Our findings also determine the positive effect on firms’ export intensity of environmental performance as a factor of specialisation and technology proficiency. 相似文献

Research on big data has highlighted that a crucial element to create value from data is the capability of aligning different stakeholders’ interests. However, it has not yet been investigated empirically how this process of alignment can be realized. We conduct a multiple case study on the two leading platforms involved in the online dissemination of cultural heritage – Europeana and Google Arts & Culture. Our findings reveal that a platform overtakes a rival one when it turns on multiple drivers of value creation in such a way that the drivers contribute to realigning the interests expressed by the stakeholders whose strategic objectives and beliefs were formerly divergent – or simply unrelated – to each other. This capability of realigning different stakeholders’ interests is independent of the level of industry-specific knowledge that the platform orchestrator has. The dynamics we document imply that Google has assumed a system integration role in the cultural ecosystem. This generates new trade-offs for museums in the way they generate value for the tourism industry. The paper enriches our understanding of what strategies digital platforms adopt to create value in big data contexts and provides a base to continue the investigation on other ecosystems driven by big data. 相似文献

This article considers the development of the group decision support system (GDSS) field both from organizational and technological perspectives. The growing importance of teamwork, lateral coordination, and activities integration inside modern business organizations is emphasized. Technological and knowledge specialization, quick transformation of business environments, reduction of response time, and so on, are some of the reasons that can explain the renewed relevance of teamwork. Also, the development of information technology (IT) is analyzed in relation to the role it is assuming in supporting group activities. Research in the GDSS field is then introduced. A proposal concerning the identification of three different phases in GDSS studies is developed, ranging from decision rooms to distributed systems. Each phase shows distinctive research topics and application fields, together with different organizational goals. Results of these developments are the growth of potential application areas of GDSS tools. These theoretical considerations, together with empirical experiences coming from the study of a real manufacturing environment (an IBM plant where group cooperation plays a fundamental role for production efficiency), constitute the basis for a research GDSS prototype (GROUPS). Prototype features are designed to support executives in facing production‐planning problems through an improvement in communications and in knowledge representation. 相似文献

While prior research mainly focused on the impact of third-party-certified web assurance seals on consumers' perceptions and purchasing behaviors, little research has been conducted on the managerial decision-making process about the selection, implementation, and the abandonment of such seals. Of particular interest here is the WebTrust seal, jointly developed by the AICPA and the CICA. We take a qualitative case study approach to understand the motivations and rationale of a large North American telecommunications firm's management behind the decisions about the selection, implementation, and abandonment of its WebTrust seal. Our case firm was one of the first to obtain the seal on its online shopping website. Semi-structured interview results suggest that the implementation and the subsequent abandonment of WebTrust may be explained by several theoretical frameworks — the managerial accounting perspective, organizational slack theory, innovation theory, and institutional theory. First, the case firm's leader attitude in innovation, its extra resources available, coupled with the endorsement of the accounting profession led to the implementation of WebTrust. Second, when the benefits of WebTrust versus its costs were questioned and other companies increasingly abandoned the seal, our case firm decided to follow this trend. 相似文献
