This article suggests a pricing model for commodities used to produce biofuel. The model is based on the concept that the deterministic component of the Wiener process is not constant and depends on time and exogenous variables. The model, which incorporates theory of storage, the convenience yield and the seasonality of harvests, was applied in the Brazilian sugar market. After predictions were made with the Kalman filter, the model produced results that were statistically more accurate than those returned by the two‐factor model available in the literature. 相似文献

ABSTRACTIn the construction of input–output models from supply-use tables, technology assumptions disambiguate how an industry uses inputs in the production recipe of multiple outputs. This paper uses Bayes' theorem to select technology assumptions, taking into account empirical observations. The paper presents a formulation to explore hybrids between product and industry technology assumptions in product-by-product tables. We then present Markov chain Monte-Carlo techniques to implement the Bayesian method for selecting technology assumptions. We apply the method in a case study using Eurostat supply-use tables of 2004 and 2005, exhibiting a volume of secondary products of less than 13%, and 59 products and industries per country. The results show that the choice of technology is not important, given that there is no strong evidence in favour of any of them. 相似文献

The identification of the entrepreneurs’ characteristics and the knowledge of the entrepreneurial profile of university students
have been assuming a growing importance in the development of educational programs directed towards the entrepreneurship and
start-up processes. This study aims to identify the factors that most contribute for the intention to start up a business.
The research also tries to identify the profile of a potential entrepreneur student concerning several characteristics: personal
attributes, family, demographic variables and motivations. Research findings include the idea that entrepreneurship education
is the most relevant factor in what concerns the propensity to business creation. On the other side, personal characteristics
have an important role in shaping motivation to start-up a business and perceived hurdles have a negative impact in the intention
to start-up. The results may be relevant when developing an adequate educational program directed to the entrepreneurship
education and start-up processes. 相似文献

In the knowledge society, universities have assumed new missions and relations in order to contribute to economic and social development, while preserving their own sustainability. This article aims to explore scientific literature on innovation and entrepreneurship in the academic setting, describing how the field is organized, main terms and definitions, theoretical frameworks, and empirical models, in order to direct future research. A systematic literature review was conducted, in which articles indexed at Web of Science were initially submitted to a bibliometric analysis. Then, the content of a set of articles best fitting the objectives of the study was analyzed. Bibliometric analysis shows an increasing literature, with publications over more than 40 years. There are studies from many disciplines, with those in business and economics prevailing, mainly related to management and originating from the USA and Europe. Content analysis shows a fragmented literature, with definitions not showing a clear relationship between innovation and entrepreneurship, or their use within universities in coherence with their traditional definitions. Both theoretical frameworks and empirical models are very heterogeneous, but four groups of studies were identified based on their theoretical frameworks, and also based on their empirical models. With only a few exceptions, empirical models do not share many components and variables, and there are no clear boundaries between the different models. Despite the increasing literature, it is still fragmented and undertheorized, requiring more systematic and holistic studies, considering both the economic and the social aspects of innovation and entrepreneurship within universities. 相似文献

The study aimed to analyze the employee's perception of the remuneration systems in two major hospitals in Brazil, one managed by the government and the other by private investors. The sample considered 109 respondents, out of which 54 were from the private hospital and 55 from the public hospital. After data collection on the sample population, perception of remuneration was associated with occupation, gender, age and experience, as suggested by the Upper Echelons Theory. The results show that remuneration is viewed as an instrument of control and behavior or a learning-inducing mechanism; however, the perceptions of employees working in the health area and administrative area were different. These findings show that the influence of fixed pay is different not only for the employees of both areas, but also in relation to the public and private hospital management. It was found that gender is not a determinant factor of behavior and that there were no differences between younger and older employees as well as between more experienced and less experienced employees with respect to the effect of remuneration on behavior. There were no differences in relation to the type of hospital either. In general, the results emphasize the importance of remuneration as an instrument of control and management, either in the context of public or private organizations. 相似文献

Municipalities are well positioned to support adaptation of vulnerable people to climate change; however, they seldom integrate climate change into their planning for social development. The building of adaptive capacity for sustainable adaptation requires that municipalities understand and mainstream climate change into their plans, and develop context-specific adaptation strategies that address existing social development issues. A desktop analysis was conducted to compare the planning landscape in six District Municipalities in the Eastern Cape, South Africa, focusing on Municipal Integrated Development Plans (IDPs). A scoring system was developed for comparing the IDPs of the municipalities, based on levels of context-specific information about climate change, mainstreaming of climate change with other development concerns, and vertical integration across district and local municipalities, amongst other themes. Overall, the mainstreaming of climate change in municipal IDPs in the Eastern Cape remains weak, and requires critical attention if sustainable adaptation is to be achieved. 相似文献

We show, using a Hotelling (1929) model with Laffont and Tirole (1986) firms, that under duopoly, the information asymmetry caused by the separation of ownership and control has two effects on owners’ incentives to induce effort. Information asymmetry raises the marginal cost of inducing effort, which decreases efforts and increases prices. Since all firms’ prices increase, this leads to a change in the expected demand of each firm, and thus in the marginal benefit of inducing effort, which may amplify or mitigate the initial impact. As a consequence, information asymmetry may induce some firms to increase efforts and lower prices. More surprisingly, it may increase both ex post and ex ante social welfare. 相似文献

In this paper we analyse whether entrepreneur location decisions differ across industries and identify the factors determining the choice of location between rural and urban environments. Firm location is based on a new taxonomy developed over the influential three dimensions of Hayter’s (1997) approach. The paper uses data from sample of one thousand Portuguese firms. We present a stylized theoretical model to determine how these new five dimensions influence firm’s location and test the model through a logistic regression. Our results show that that the location decisions depend on the sector of activity, type of area (urban vs. rural) and the characteristics of the entrepreneur. We find that companies engaged in knowledge intensive business services prefer to locate in urban areas. From an institutional point of view, firms prefer to locate in rural areas. 相似文献

Despite the economic relevance and distinctiveness of family firms, little attention has been devoted to researching their nature and functioning. Traditionally, family firms have been associated both to positive and negative features in their relationships with the stakeholders. This can be linked to different orientations toward corporate social responsibility. Thus, this research aims to identify the approaches that Spanish family firms maintain about social responsibility, based on the model developed by Quazi and O Brien Journal of Business Ethics 25, 33–51 (2000). An empirical study carried out for 112 Spanish family firms gives support to our initial assumption about these organizations not being a homogeneous group in terms of their orientation towards corporate social responsibility. The differences in perceptions do not seem to be associated to biographical characteristics. These results lead to some relevant academic and practical implications that suggest interesting lines for future research.María de la Cruz Déniz Déniz is professor in the Department of Management at Las Palmas de Gran Canaria University (Spain).

We study the asset‐pricing implications of technological growth in a model with “small,” disembodied productivity shocks and “large,” infrequent technological innovations, which are embodied into new capital vintages. The technological‐adoption process leads to endogenous cycles in output and asset valuations. This process can help explain stylized asset‐valuation patterns around major technological innovations. More importantly, it can help provide a unified, investment‐based theory for numerous well‐documented facts related to excess‐return predictability. To illustrate the distinguishing features of our theory, we highlight novel implications pertaining to the joint time‐series properties of consumption and excess returns. 相似文献
