Declining response rates and the potential for deterioration in the quality of survey data require reconsideration of the role of incentives to participate in interviews. This article argues that the strategies associated with linking public goods to private goods to establish reputation effects for the private goods involved can also be used to enhance confidence in the objectives of the request for an interview. In this literature, an assured reputation is established for those selling products by offering to contribute some of the proceeds of a sale to charity. The results of our field experiment indicate that combining charity with financial incentives appears to increase confidence in survey objectives for those familiar with the interview process.  相似文献

In this paper, we introduce an analytical framework – called the Triple Uncertainty (TU) – that casts strong doubt on both the existence of a linear path leading to organisational innovation and the alleged accuracy of most R&D performance metrics. This framework, grounded on both the analysis of field-data and actor-network theory underpinnings, emphasises the importance of a series of uncertainties that pervade the management of techno-scientific projects. According to the TU framework, the management of techno-scientific projects hinges on the choice of mode of organisational coordination. To illustrate this thesis, we analyse in this paper the managerial complexities of a techno-scientific R&D project at Tenaris (a world-leading manufacturer of steel-tubes) whose intended outcome is a computer simulation of a critical industrial process.  相似文献

This paper examines the empirical validity of the hypothesis of uncovered interest parity (UIP) using data from five Central and Eastern European countries with floating exchange rates for the period 2003 to 2014. The analysis includes forward‐looking as well as static expectations and allows for different types of structural break. The variable depicting the deviation from strict UIP is stationary when expectations are forward looking, suggesting that it is not possible to reject the UIP hypothesis with a constant risk premium. The deviation from strict UIP is however typically not stationary when expectations are static, even when structural breaks are incorporated, leading to the rejection of the UIP hypothesis with a constant risk premium. The results underscore the central role of expectations for the UIP hypothesis.  相似文献

Feeder cattle is one of the most important commodities in the livestock industry worldwide. Nonetheless, beef production is subject to many uncertainties; therefore, the risk management tools that agents use must be efficient. This article discusses the financial options available in the Brazilian futures market to feeder cattle producers and describes the best risk pricing model to determine the option premium. Our results consider several option pricing models and different types of volatility. The best pricing is obtained with the model of Bjerksund and Stensland with the implied volatility.  相似文献

The Riotinto and Almadén mining areas in Spain are two of the best examples of European experiences in restoring the heritage of traditional mining activities. Initially promoted by public administrations, particularly municipal bodies, with the active participation of private companies and the local community, these projects are an international reference in the protection and preservation of the mining-industrial heritage and the tourist use of buildings, machines and landscapes.  相似文献

This paper proposes a quantile regression estimator for a heterogeneous panel model with lagged dependent variables and interactive effects. The paper adopts the Common Correlated Effects (CCE) approach proposed in the literature and demonstrates that the extension to the estimation of dynamic quantile regression models is feasible under similar conditions to the ones used in the literature. The new quantile regression estimator is shown to be consistent and its asymptotic distribution is derived. Monte Carlo studies are carried out to study the small sample behavior of the proposed approach. The evidence shows that the estimator can significantly improve on the performance of existing estimators as long as the time series dimension of the panel is large. We present an application to the evaluation of Time-of-Use pricing using a large randomized control trial.  相似文献

Occupational accidents caused by electrical contact are a major concern worldwide due to their severe consequences. The study conducted is based on an analysis of the evolution of incidence rates and dependence between variables for 14,022 electrical accidents occurring in Spain between 2003 and 2012. The results show that electrical accidents as a whole are 3.6 times more likely to have severe consequences than the rest of the accidents in the country. This proportion is even nine times greater in the case of fatal accidents. They also confirm a significant relationship between the severity of this type of accidents and the economic sector in which they occur. On the other hand, there is a positive trend in the reduction of the incidence rate, especially in relation to direct contact, although unexpectedly the rate of accidents due to indirect contact is on the rise. Thus, preventing electrical occupational accidents requires efforts to guarantee adequate training adapted to the needs of workers in the various economic sectors. Furthermore, those responsible for safety should work to implement mechanisms to monitor and control compliance with efficient protective measures against electrical contact.  相似文献

New value‐creation opportunities mean the future of supply chain management (SCM) is bright. Growing C‐suite sponsorship for supply chain contributions to enterprise value creation is a positive factor for the future of the discipline. However, rising C‐suite requests mean that supply chain professionals must manage an internal triad of relationships: horizontally with peer functions and vertically with C‐level executives. How well supply chain professionals manage this triad will determine SCM's future role in strategic initiatives. We use procurement to exemplify the opportunities and challenges that confront a maturing supply chain discipline. Focus studies conducted with procurement managers and peer functional managers combined with C‐suite interviews reveal: (1) great opportunities for cementing SCM's value‐creation role; and (2) existing gaps hinder identity construction and professional contribution.  相似文献

In this paper, we first establish the core, fundamental concepts of Williamson’s TCE, examining the different governance structures or the institutional alternatives that TCE theory proposes. We go on to describe some critical considerations and theoretical proposals that correspond fundamentally to Williamson’s heuristic model, the integration of incentives in organizational forms, idiosyncratic demand, and how the concept of transaction is conceived in general.  相似文献
