The purpose of this article is to evaluate the performance of market advisory services for the 1995–2003 corn and soybean crops. A new database from the Agricultural Market Advisory Services (AgMAS) Project is used in the evaluation. This database should not be subject to survivorship and hindsight biases. Overall, the results provide little evidence that advisory services as a group outperform market benchmarks, particularly after considering risk. The evidence is more positive versus the farmer benchmarks, even after taking risk into account. Results also suggest that it is difficult to predict the pricing performance of advisory services across crop-years. 相似文献

A number of authors within business marketing and purchasing, have stressed that the heterogeneity of relationships in customer and supplier portfolios are a source of managerial problems and opportunities. This paper looks at the use and development of firms’ capabilities in the context of relationship portfolios. Two case studies about producers of moulds are used to illustrate how their contrasting trajectories in terms of degree of specialisation can be related to the variety found and sought in their portfolios of relationships. Our study suggests that portfolio interdependencies are best understood in the context of the development of idiosyncratic capabilities, which include interpretations and experiences in using and influencing that variety. 相似文献

Asset Pricing Implications of Firms' Financing Constraints 总被引:1,自引:0,他引:1
We use a production-based asset pricing model to investigatewhether financing constraints are quantitatively important forthe cross-section of returns. Specifically, we use GMM to explorethe stochastic Euler equation imposed on returns by optimalinvestment. Our methods can identify the impact of financialfrictions on the stochastic discount factor with cyclical variationsin cost of external funds. We find that financing frictionsprovide a common factor that improves the pricing of cross-sectionalreturns. Moreover, the shadow cost of external funds exhibitsstrong procyclical variation, so that financial frictions aremore important in relatively good economic conditions. (JELE22, E44, G12) 相似文献

This work investigates the relationship between intellectual capital and value creation in the sector of production and assembly of vehicles and auto-parts in Brazil. Through the access of the database from the annual industrial research conducted by the Brazilian Institute of Geography and Statistics, we gathered 865 observations, from 2000 to 2006, of public and private Brazilian companies with more than 100 employees. The database allows the estimate of relevant aggregated variables such as national accounts, gross domestic product, intermediate consumption, as well as propitiates a sectorial study of business strategies and performance, including value added by individual companies. In particular, in this study we use data on variables associated to intellectual capital. To achieve the goal of the study, we consider intellectual capital as defined by Pulic (2000, 2002), including human capital and structural capital. For the analysis of business performance, we used Pulic's VAIC (Value Added Intellectual Cofficient) index as a measure of efficiency of the employed financial and intellectual capital. Regression models were run to verify the relationship among the efficiency in the use of intellectual capital and the profitability of Brazilian companies. The gross income, calculated as before selling, general and administrative expenses, depreciation expenses, amortization and interest expenses, was used as measure of the flows of value creation and the profitability was measured by the gross income to the total assets of the companies. Considering the constructs defined by Pulic (2000, 2002), we tested, for the Brazilian sector of Production and Assembly of Vehicles and Auto-parts, the following hypotheses: (l) there is a positive relationship between value creation and intellectual capital, (2) there is a positive relationship between value creation and stock of intellectual capital, (3) there is a positive relationship between value creation and efficiency of the employed capital, (4) there is a positive relationship between value creation and efficiency of the human capital, (5) there is a positive relationship between value creation and efficiency of the structural capital. The results of the study, obtained through panel data analysis and through the use static and dynamic models, support the hypotheses that the intellectual capital of the companies, in its flow and stock dimensions, is positively and significantly related to value creation. 相似文献

As the worldwide financial crisis is directly connected to the transport sector, public transport systems become a central player to support economic recovery. Transit services are facing a number of challenges as a consequence of this severe crisis. However, each attribute characterizing transit services has evolved in a different manner, thereby raising some chances and opportunities at some specific areas. This study investigates the evolution of service quality on a metropolitan transit system under economic crisis conditions. We used data from three customer satisfaction surveys (2008, 2011, and 2014) conducted at the bus transit service of the metropolitan area of Granada (Spain). Principal component analysis (PCA) and structural equation modeling (SEM) approaches were applied. PCA results show that the attributes describing the service were grouped into two levels of dimensions according to their impact on users' overall satisfaction (Transport Service Factors and Comfort and Convenience Factors). Subsequently, following a competing model strategy, the existing relationships between users' satisfaction and perception of service quality dimensions were ascertained. Finally, three SEMs were calibrated, one for each year under study, and were subjected to a multigroup analysis to test for equivalence among the three models. The outcomes show that fare of the ticket has lost importance as the financial crisis has become more noticeable and that Transport Service Factors had lower influence and users' satisfaction in 2011, when downturn was more intense. 相似文献

Between September 2005 and October 2007, representative companies of the Brazilian residential real estate market adopted a strategy intended to increase their investment capacity by Initial Public Offer (IPO). The setting at that time was favorable for constructing residential real estate designed for the middle class, in view of two main factors: First, in 2005, a restructuring of the Brazilian finance system had relaxed requirements needed to receive financing for the purchase of residential property; Second, there was substantial demand in the middle class market because most developers had been focusing on the upper class market in order to guarantee the sale resources in the production phase. Thus, it was necessary to enhance the investment capacity of the real estate companies to attend the middle-class demand. These two factors, associated with a favorable outlook for the Brazilian, as well as the global economy, encouraged those representative companies to rapidly increase their investment capacity by IPO in a short time. The focus of this article is to analyze the quality of the investments in the stock of these real estate companies (21 offers were taken into account in the analysis). In order to identify what these companies' expectations were and how they supported their decisions to enter BOVESPA with their designated prices and amounts, correlating offers against the BOVESPA Index (market index) were also analyzed. The results allow concluding that these offers were not supported by validated procedures of pricing, but rather were just speculative offers, even though we do take into account the investment grade granted to the Brazilian economy within the period concerned in our analysis. 相似文献
