Payments for environmental services (PES) have gained wide popularity as approaches to promote environmentally friendly land use or agricultural production practices. Yet academics have also voiced concerns against seeing PES as a panacea. This article discusses whether PES is an appropriate and promising approach to promote so‐called “climate‐smart agriculture” (CSA) practices, which we define as agricultural production practices that contribute to CO2 emission reductions and/or removals and provide benefits to farmers via increased productivity and profits and reduced vulnerability to climate change. PES appears most promising for the promotion of CSA practices in small‐scale farming contexts with low incomes. Effective design, however, requires solid estimates of cost and benefit flows from CSA adoption over time, accounting for differences in socioeconomic and ecological conditions, and addressing the risk of leakage. Funding for such PES will likely have to come from public sources, and seems most promising where synergies with other objectives such as agricultural development, food security, and climate adaptation or other environmental services exist. The potential of alternative approaches for CSA support such as taxation with rebates for CSA practices, CSA‐related investment support such as microcredits, and hybrid approaches such as conditional microcredit should be further investigated. 相似文献
We use a movie industry project‐by‐project data set to analyze the principal–agent problem in slate financing arrangements. Under this specific film financing regime, which has become a significant mode of raising capital in Hollywood over the past decade, an external investor concludes a long‐term contract with a film producer and commits to cofinance a larger number of future film projects of that particular partner. In line with our theoretical conjectures, slate cofinanced movies receive poorer quality ratings and yield considerably lower return rates. Our data suggests that a substantial part of these performance differences may be attributed to adverse project selection and producer moral hazard. 相似文献
The customer value proposition (CVP) has a critical role in communicating how a company aims to provide value to customers. Managers and scholars increasingly use CVP terminology, yet the concept remains poorly understood and implemented; relatively little research on this topic has been published, considering the vast breadth of investigations of the value concept. In response, this article offers a comprehensive review of fragmented CVP literature, highlighting the lack of a strong theoretical foundation; distinguishes CVPs from related concepts; proposes a conceptual model of the CVP that includes antecedents, consequences, and moderators, together with several research propositions; illustrates the application of the CVP concept to four contrasting companies; and advances a compelling agenda for research. 相似文献
A major gap in our understanding of the medieval economy concerns interest rates, especially relating to commercial credit. Although direct evidence about interest rates is scattered and anecdotal, there is much more surviving information about exchange rates. Since both contemporaries and historians have suggested that exchange and rechange transactions could be used to disguise the charging of interest in order to circumvent the usury prohibition, it should be possible to back out implied interest rates from exchange rates. The analysis presented in this article is based on a new dataset of medieval exchange rates collected from commercial correspondence in the archive of Francesco di Marco Datini of Prato, c. 1383–1411. It demonstrates that the time value of money was consistently incorporated into market exchange rates. Moreover, these implicit interest rates are broadly comparable to those received from other types of commercial loan and investment. Although on average profitable, the return on any individual exchange and rechange transaction did involve a degree of uncertainty that may have justified their non‐usurious nature. However, there were also practical reasons why medieval merchants may have used foreign exchange transactions as a means of extending credit. 相似文献
In this paper, we show that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest‐ and lowest‐paid jobs compared to middle‐wage jobs. The most popular explanation for such a pattern is the hypothesis of task‐biased technological change, where technological progress reduces the demand for routine middle‐wage jobs but increases the demand for non‐routine jobs located at the tails of the job–wage distribution. However, our estimates do not support this explanation for the 1970s and 1980s. Stronger evidence for task‐biased technological change, albeit not conclusive, is found for the 1990s and 2000s. In particular, there is both a statistically and economically significant growth of non‐routine jobs and a decline of routine jobs. However, results for wages are mixed; while task‐biased technological change cannot explain changes in between‐occupation wage differentials, it does have considerable explanatory power for changes in within‐occupation wage differentials. 相似文献
We examine in the laboratory how having the opportunity to donate to a charity in the future affects the likelihood of engaging in dishonest behavior in the present. We also examine how charitable donations are affected by past ethical choices. First, subjects self-report their performance on a task, which provides them with an opportunity for undetected cheating. In the second stage they can donate some of the money earned in the first stage to a charity. Only subjects in the treatment group know about the opportunity to donate in the second stage. We find that more subjects cheat if they know they can donate some of the money to charity. We also find that subjects in treatment end up donating less to charity and that both honest and dishonest subjects donate less in treatment. We propose a new hypothesis that explains these results: past violations of social norms numb one’s conscience, leading to more antisocial behavior. 相似文献
Providing consumers with unique experiences and immersing them in original contexts are the goals of web entrepreneurs. Researchers and web entrepreneurs have expressed a particular interest in the online customer experience, agreeing on its importance in creating satisfaction, revisiting intention, e-trust and e-loyalty. This paper explores customer experience in the online retail context. The online customer experience is central in forming customers’ perceptions of expectations of online retailers because this experience is highly personal. However, empirical research on the online customer experience remains scarce. The objectives of this unique study are twofold. The first is to compare the effect of online customer experience on the responses of Romanian and Tunisian customers. The comparative analysis is based on two dimensions of the online customer experience assessment tool. These dimensions are cognitive experiential state (flow) and affective experiential state. The second objective is to examine the contribution of each of these two dimensions in explaining overall perceived value, e-satisfaction, e-trust and repurchase intention in the online context, as well as their effects on web entrepreneurial initiatives. The findings reveal the impact of cultural influences on the constructs embedded in the research framework. The implications for practice relate to the increasing importance of online customer experience in tailoring online marketing campaigns. The implications for web entrepreneurship are clearly emphasised by the pathways from online customer experience to entrepreneurial initiatives. These pathways capture the value of customer-generated content in designing innovative business models.
We treat the parameter estimation problem for mean‐field models of large interacting financial systems such as the banking system and a pool of assets held by an institution or backing a security. We develop an asymptotic inference approach that addresses the scale and complexity of such systems. Harnessing the weak convergence results developed for mean‐field financial systems in the literature, we construct an approximate likelihood for large systems. The approximate likelihood has a conditionally Gaussian structure, enabling us to design an efficient numerical method for its evaluation. We provide a representation of the corresponding approximate estimator in terms of a weighted least‐squares estimator, and use it to analyze the large‐system and large‐sample behavior of the estimator. Numerical results for a mean‐field model of systemic financial risk highlight the efficiency and accuracy of our estimator. 相似文献
