A systems model was estimated to determine the effects of declining U.S. retail beef demand on farm-level beef prices and production. Retail beef demand declined by nearly 66% from 1976 to 1999. Results indicate autonomous shifts in retail demand significantly impacted farm-level demands and production. Based on equilibrium multipliers, the 1976–99 reduction in beef demand decreased real slaughter cattle prices and production by 32.1% and 11.2%, respectively. Real feeder cattle prices and production decreased by 8.0% and 22.6%, respectively. Combining the decreases in farm prices and production, slaughter and feeder cattle producers experienced a real revenue reduction of $13.3 billion (61%) due to the long-term decline in demand.  相似文献

The objective of this article is to analyze the domestic and international effects of a hypothetical foot‐and‐mouth disease (FMD) outbreak in the Mexican cattle industry. A discrete time dynamic optimization model of the Mexican cattle sector is specified, and linked to domestic and international markets. Economic consequences of FMD outbreaks are simulated over time and under different scenarios. Specific findings and general policy recommendations are provided. The study reports a range of outbreaks from localized to large scale and suggests that changes in economic surplus due to FMD range from a positive net gain of $0.89 to $1.6 billion to a net loss of about $67 billion, depending on the specific mitigation strategy and outbreak scenario.  相似文献

Australia is the sixth largest producer of beef and the second largest exporter of beef. Average beef exports from Australia are approximately 65 per cent of the total amount of beef produced, about 1.3 million tonnes. Australia is particularly vulnerable to diseases that are not endemic to the country and could close or disrupt its export markets for beef. In this study, we construct a bioeconomic optimisation model of the Australian beef industry that captures production and consumption decisions, domestically and internationally, and the impacts on the beef industry of a potentially catastrophic disease, foot‐and‐mouth disease (FMD). This study analyses localised to large‐scale outbreaks and suggests that changes in economic surplus because of FMD range from a positive net gain of $57 million to a net loss of $1.7 billion, with impacts on producers and consumers varying depending on the location of the outbreak, control levels and the nature of any trade ban.  相似文献

Creative destruction Zhu Jia Jiao, China   总被引:2,自引:0,他引:2  
Chinese water towns have experienced tourism investment since the adoption of the Open Door Policy in 1978. These river-based settlements offer an ancient small-town atmosphere, historic architecture, and a diversity of heritage commodities. The implications of this development in one such town, Zhu Jia Jiao, are examined through application of the model of creative destruction. Data collected on investments, tourist numbers, and resident attitudes reveal that this destination is in the model’s second stage of advanced commodification, which may be maintained if limits are placed on arrivals. Findings should be beneficial to other communities which are basing their development on marketing small-town heritage.  相似文献

Many multinationals rely on acquisitions when expanding internationally. However, cross‐border integration processes are complex and often result in a looser integration than intended. In this study, we examine the postacquisition process in a multinational seeking global integration of its geographically dispersed organizational units. We find that politicization and ambiguity lead to integration vacuum where top‐down initiatives fail to achieve desired integration outcomes. However, the integration vacuum creates expanded space of action for the acquired firm to initiate unexpected bottom‐up integration. We contribute to the literature on multinationals by illuminating the challenges they face when extending their dominant strategic logic to international acquisitions. Furthermore, we identify the process through which politicization and ambiguity lead to integration vacuum that allows the foreign subsidiary an expanded space of action wherein it can initiate bottom‐up integration efforts. © 2013 Wiley Periodicals, Inc.  相似文献

There are a range of solutions that address asset building challenges for low-wealth women. Here we highlight some solutions that focus on basic needs (child care, child support) and creating economic stability with disposable income (income available after basic needs are met); solutions that address predatory lending and the housing crisis; and solutions that focus on joint ownership of assets and community-based asset building.  相似文献

This research examines selected empirical properties of duality relationships. Monte Carlo experiments indicate that Hessian matrices estimated from the normalised unrestricted profit, restricted profit and production functions yield conflicting results in the presence of measurement error and low relative price variability. In particular, small amounts of measurement error in quantity variables can translate into large errors in uncompensated estimates calculated via restricted and unrestricted profit and production functions. These results emphasise the need for high quality data when estimating empirical models in order to accurately determine dual relationships implied by economic theory.  相似文献
