We present an empirical analysis of how buyer (and trader) attributes influence decisions of market participation and channel choice among smallholder potato farmers in West Java, Indonesia. We use a best–worst scaling experiment to evaluate the determinants of these decisions and gauge the influence of buyer attributes. Our latent-class cluster analysis reveals that producers have heterogeneous preferences for buyer attributes, which address classic smallholder constraints such as access to inputs, credit, and information. This heterogeneity can be somewhat explained by household characteristics and assets. The broad mass of our sample sought buyers whose attributes imply lower market risk for farmers. Yet roughly a quarter of our sample, a portion that included farmers with large, specialised farms, sought buyers who could provide inputs such as high-quality seeds.  相似文献

Scholars in the fields of organization and strategic communication have long been interested in organizational identification as a phenomenon favoring employees’ alignment with corporate values and consequently achievement of the organizational mission. To date, most studies on the subject have relied on social identity theory, which focuses on cognitive categorization processes but overlooks the role of employees’ relationships within their organization. In this research, we introduce a social capital perspective into organizational identification models. We propose and test a model looking at the influence of an individual’s social capital, a variable deriving from different dimensions of an individual’s communication network (i.e., prestige, resourceful others, friendship), on organizational identification, mediated by the attractiveness of perceived organizational identity. The results from a survey conducted in a business organization suggest that a person’s social capital influences organizational identification, both directly and through the attractiveness of perceived organizational identity. Our organizational identification model contributes to extend knowledge on the complementarity of the cognitive and relational perspectives of strategic communication and on the role of relationship building and networks in strategic communication management.  相似文献

This study investigates the market value of corporate cash holdings in connection with firm-specific and time-varying information asymmetry. Analyzing a large international sample, we test two opposing hypotheses. According to the pecking order theory, adverse selection problems make external financing costly and imply a higher market value of a marginal dollar of cash in states with higher information asymmetry. In contrast, the free cash flow theory predicts that excessive cash holdings bundled with higher information asymmetry generate moral hazard problems and lead to a lower market value of a marginal dollar of cash. We use the dispersion of analysts’ earnings per share forecasts as our main measure of firm-specific and time-varying information asymmetry. Extending the valuation regressions of Fama and French [Fama, E.F., French, K.R., 1998. Taxes, financing decisions, and firm value. Journal of Finance 53, 819–843], our results support the free cash flow theory and indicate that the value of corporate cash holdings is lower in states with a higher degree of information asymmetry.  相似文献

This study shows the market value of gold mining firms contains a premium for the option to close. The sample uses 41 gold mining producers listed on the Australian Stock Exchange from 1987 to 2013. The premium of the market price over the present value of cash flows is isolated and a pooled cross‐sectional regression tests the degree of association between that premium and theoretical option premiums. The results show market prices incorporate a premium reflecting the option to temporarily close operations. The magnitude of the option premium to close depends on whether firms are out or in the money options.  相似文献

Introduction: Long-term exposure to calcineurin inhibitor-based immunosuppressant (IS) therapy in liver transplant (LT) recipients is associated with renal complications. In the randomized trial H2304, everolimus?+?reduced-dose tacrolimus (EVR?+?rTAC) demonstrated equivalent efficacy and superior renal function compared to standard-dose tacrolimus.

Methods: To evaluate the cost-effectiveness of EVR?+?rTAC vs TAC, in de novo LT patients, a Markov model simulating both liver and kidney function was developed and estimated the long-term outcomes of IS following LT. The analysis used the Italian healthcare payer perspective.

Results: Patients treated with EVR?+?rTAC gained on average 1.92 years and 1.62 quality-adjusted life years (QALYs). The incremental cost-effectiveness ratios (ICER) were €35,851 and €42,567 for LY gained and QALY gained, respectively. For the hepatitis-c sub-population, the ICERs decreased to €22,519 and €30,658, respectively.

Conclusion: EVR?+?rTAC improves survival and quality-of-life and is a cost-effective alternative to calcineurin-inhibitor monotherapy for patients requiring LT.  相似文献

We provide a respecification of an integer programming characterization of Arrovian social welfare functions introduced by Sethuraman et al. (Math Oper Res 28:309–326, 2003). By exploiting this respecification, we give a new and simpler proof of Theorem 2 in Kalai and Muller (J Econ Theory 16:457–469, 1977).  相似文献

This paper provides an overview of the implications of integrating marketing and purchasing offered by traceability. The research offers some evidence of the adoption of different traceability approaches by actors along the supply chain, illustrating the relevance of the traceability issue and how traceability can be exploited. The paper presents findings from a case analysis process of five actors in the fashion industry. This industry has experienced strong integration between industrial and retail functions and relevant changes in the organisation of production networks (global shift of production to new industrialized countries and emerging markets) which place emphasis on the traceability topic. Traceability emerges as a complex concept that concerns the sharing of information about the product and production processes along the supply chain in BTB networks up to the consumers in the final market. The issue analysed focuses on organising, with a discussion of two different uses of traceability: traceability as a tool for inter-organisational control and traceability as a tool for market power. The two approaches give rise to different implications at the individual company and business network levels. The traceability process has intraorganisational consequences in terms of contents, technologies and actors involved in its implementation. These consequences are different according to the role played by the process.  相似文献

In this paper, we present the results of a Learning-to-Forecast Experiment (LtFE) where we eliciting short- as well as long-run expectations regarding the future price dynamics in markets with positive and negative expectations feedback. Comparing our results on short-run expectations with the LtFE literature, we prove that eliciting long-run expectations has no impact on the price dynamics nor on short-run expectations formation. In particular, we confirm that the Rational Expectation Equilibrium (REE) is a good benchmark only for the markets with negative feedback. Interestingly, our data show that while the term structure of the cross-sectional dispersion of expectations is convex in positive feedback markets, it is concave in negative feedback markets. Differences in the slope of the term structure stem from diverse degrees of uncertainty regarding the evolution of prices in the two feedback systems: (1) in the negative feedback system, the convergence of the price to the REE reflects a tendency for coordination of long-run expectations around the fundamental value; (2) conversely, oscillatory price dynamics observed in the positive feedback system is responsible for the diverging pattern of long-run expectations. Finally, we propose a new measure of heterogeneity of expectations based on the scaling of the dispersion of expectations over the forecasting horizon.

The adoption and diffusion of environmental innovations (EIs) is crucial to greening the economy and achieving win–win environmental/economic gains. A large and increasing literature has focused on the levers underlying EIs that are external to the firm, such as stakeholder and policy pressures. Little attention, however, has been devoted to the possible role of local spillovers of a sector/geographical nature as a factor that correlates with EIs and economic performances. A rich data set that covers the innovative activities and economic performances of firms in the Emilia-Romagna region in Italy, an area dense in manufacturing districts, is analysed. EIs’ drivers and effects on firms’ performance are investigated through a two-step procedure. First, we examine the relevance of spatial levers, namely, whether high rates of eco-innovators in a given local area induce the adoption of EIs in firms located in the same local area. The role of the ‘agglomeration lever’ turns out to be fairly local in nature: we find that spillovers are significantly inducing innovation within municipal boundaries. Second, we test whether EIs adoptions have significantly increased firms’ economic performances and find that some firms’ productivity performances are positively related to EI adoption.  相似文献
