The effect of carcass quality uncertainty on the structure of the slaughter cattle market is investigated. A theoretical extension of the “Theory of Factor Price Disparity” is provided. It is demonstrated that the coexistence of a risk premium wedge between marketing channel (live weight, dressed weight, and grid) pricing mechanisms, in conjunction with varying degrees of producer risk aversion or producer perception of carcass quality uncertainty, contributes to the coexistence of multiple marketing channels. It is also demonstrated that risk and risk preference provide the linkage between carcass quality uncertainty and producer marketing decisions. We demonstrate how this linkage can affect the structure of the fed cattle market and the variability in slaughter volume across marketing channels. We also confirm the linkage between value‐based production techniques that increase seller information on carcass quality and seller increased usage of grid pricing regardless of actual carcass quality. Empirical evidence is provided in support of the supposition that carcass quality uncertainty plays a role in grid market share variability.  相似文献

A limited number of studies have applied bibliometric visualisation to explore the network structure of scholarly tourism knowledge. This study uses CiteSpace to analyse and visualise the intellectual structure of the tourism crisis and disaster management (TCDM) field. The use of new bibliometric visualisation techniques makes a methodological contribution to the mapping and presentation of bibliometric data in tourism research. Potentials for using these methods to provide new insights into research patterns and gaps are illustrated with an analysis of the TCDM literature. The study demonstrates how bibliometric visualisation can provide new insights into an area of literature by better communicating key findings, facilitating the exploration of data, and providing rich information to readers. Findings indicate that TCDM research has moved from broader topics to more specific issues, with a more recent focus on resilience and economic crises. The visualisation of co-authorship networks reveals that major collaborative networks are based on geographic and institutional proximity, dominated by scholars in the United States, United Kingdom, and Australia. Seven major research clusters are identified from the visualisation of a co-citation network. The identification of structural holes and bridging papers draws attention to research gaps and future research opportunities in the TCDM field.  相似文献

Assessment is a growing priority among the academy and also appears to be of increasing interest among academic‐based leadership education programs. This article offers a brief history of assessment within higher education as well as an overview of the current state of assessment in the context of academic‐based leadership education programs. While there are numerous studies reporting on assignment‐ and course‐level assessment activities, comparatively limited literature addresses program‐level assessment. It is the author's assertion that we must raise the level of conversation within our emerging discipline to identify effective best practices.  相似文献

This paper analyses the role of global land management alternatives in determining potential greenhouse gas mitigation by land-based activities in agriculture and forestry. Land-based activities are responsible for over a third of global greenhouse gas emissions, yet the economics of land-use decisions have not been explicitly modeled in global mitigation studies. In this paper, we develop a new, general equilibrium framework which effectively captures the opportunity costs of land-use decisions in agriculture and forestry, thereby allowing us to analyse competition for heterogeneous land types across and within sectors, as well as input substitution between land and other factors of production. When land-using sectors are confronted with a tax on greenhouse gas emissions, we find significant changes in the global pattern of comparative advantage across sectors, regions, and land types. Globally, we find that forest carbon sequestration is the dominant strategy for GHG emissions mitigation, while agricultural-related mitigation comes predominantly from reduced methane emissions in the ruminant livestock sector, followed by fertilizer and methane emissions from paddy rice. Regionally, agricultural mitigation is a larger share of total land-use emissions abatement in the USA and China, compared to the rest of the world, and, within agriculture, disproportionately from reductions in fertilizer-related emissions. The results also show how analyses that only consider regional mitigation, may bias mitigation potential by ignoring global market interactions. For example, USA-specific analyses likely over-estimate the potential for abatement in agriculture. Finally, we note that this general equilibrium framework provides the research community with a practical methodology for explicit modeling of global land competition and land-based mitigation in comprehensive assessments of greenhouse gas mitigation options.  相似文献

American and foreign businesses, politicians, and media have all pointed to post-9/11 changes in visa policies as being responsible for the sharp decline in travel to the United States following the attacks. Using an empirical model which distinguishes the impact of visa policy from economic and country-specific factors, we find that changes in visa policy were not important contributors to the decrease in travel to the United States. Rather, the reduction in entries was largest among travelers who were not required to obtain a visa.  相似文献

Hedonic valuation of urban forest amenities tends to assume that these attributes are exogenous to sample selection, which might render the estimated results misleading. This article intends to estimate the house price differential of urban tree cover by considering the sample selection issue. The main hypothesis is that houses with high tree cover generates higher utility to consumers, and thus leads to higher house price, ceteris paribus. It may attribute to the fact that consumers self-select into purchasing houses with high- or low-density tree cover based on some unobserved systematically different characteristics. As a result, estimates from sample selection models confirm the hypothesis that purchasing a house with high-density tree cover leads to a positive price differential compared with the low-density tree cover in Napa, Los Angeles, and that buying a low-density tree cover house results in negative price differential in Napa, Los Angeles.  相似文献

Using recruiting rankings from Rivals.com, the authors examine the determinants of recruiting success among D1 NCAA men’s basketball programmes. After controlling for a host of potentially relevant variables, the authors find that recruiting outcomes are correlated with recent on-court success, historical on-court success, stadium size and playing in a ‘power’ conference. Additionally, teams with a history of sending players to the NBA receive heightened recruiting outcomes. A team with a new coach can expect difficulties with recruiting, while head coaches with national championships receive a recruiting boost. Finally, the authors show that recruiting strategies for guards may differ from recruiting strategies for other players.  相似文献

ABSTRACT

Voluntary carbon offsetting by air passengers could help counteract environmental damage caused by air travel. But adoption rates among air travellers are low. This study (1) develops new communication messages which counteract barriers to carbon offsetting identified in prior studies, and (2) tests their effectiveness using psychophysiological and attitudinal measures, a technique new to sustainable tourism research methodologies. Results point to low levels of traveller awareness of carbon offsetting schemes, the primary need for any message to attract the air passengers’ attention, the superiority of pictorial and short textual information as well as the identification of particularly effective content. The study makes three key contributions: (1) it highlights the critical importance of awareness raising as a precursor of behavioural change, (2) it offers tangible recommendations for improving carbon offsetting messages, and (3) it demonstrates the usefulness of psychophysiological measures for pre-testing alternative social marketing messages aimed at increasing environmentally sustainable tourist behaviour across a range of applications. Findings of considerable practical importance include refinements of current messages to increase both attention levels and emotional arousal, and the positive impact of promoting additional social co-benefits alongside environmental benefits. Future valuable research themes using psychophysiological and attitudinal measures are suggested.  相似文献

The recent growth of e‐commerce technologies has disrupted the traditional retail environment, leading to more consumers shopping online. While the manner in which consumers shop is changing rapidly, our understanding of how changing consumer behaviors affect retail supply chain management is lacking. In particular, our understanding of how consumers react to stockouts in an online shopping environment remains unclear. Making the challenge even more difficult is the fact that price promotions are heavily used to attract consumers in an online retail environment where consumer switching costs are low. This research develops a theoretical framework, based on expectation‐disconfirmation theory, to explain the effect of price promotions on consumer expectations of product availability and their reactions to stockouts in an online retail environment. Surprisingly, our findings suggest that consumers are actually less dissatisfied with a stockout of a price promoted item than a nonprice promoted product and are less likely to switch to another retailer's website. These findings may suggest that price promotions actually create a type of switching cost in the online retail environment, leading to interesting implications for researchers and supply chain managers.  相似文献
