Presidential candidates purchase advertising based on each state’s potential to tip the election. The structure of the Electoral College concentrates spending in battleground states, such that a majority of voters are ignored. We estimate an equilibrium model of multimarket advertising competition between candidates that allows for endogenously determined budgets. In a Direct Vote counterfactual, we find advertising would be spread more evenly across states, but total spending levels can either decrease or increase depending on the contestability of the popular vote. Spending would increase by 13 % in the extremely narrow 2000 election, but would decrease by 54 % in 2004. These results suggest that the Electoral College greatly increases advertising spending in typical elections. 相似文献

Wheat protein is one of the most important specifications used in domestic and import purchase contracts and is used partly as a proxy for functional quality. The purpose of this article is to analyse the demand for wheat delineated by protein class. A choice‐based econometric model is specified and estimated using a novel dataset of pooled wheat shipments to individual importing countries. Buyers are importing countries that make purchase decisions among different protein levels. The model frames the choice in terms of attributes of the choice and of the importing countries. Results indicate that there have been shifts over time, and purchase probabilities are highly price elastic and vary across importing regions. Functional characteristics including wet gluten content and extraction rates have significant impacts on purchase probabilities. These results have implications for breeders as it clearly illustrates the role of protein and functional characteristics on demand. The results also have implications for analysts modelling wheat trade in that there are many factors impacting market segments that would not be captured in conventional demand specifications. 相似文献

Technology Foresight for Wiring Up the National Innovation System: Experiences in Britain, Australia, and New Zealand 总被引:1,自引:0,他引:1
Since 1990, technology foresight has spread rapidly. We begin by analyzing the reasons for this before examining the specific political background to technology foresight in the United Kingdom, Australia, and New Zealand. The article analyzes and compares the approaches to foresight in these countries, identifying the strengths and weaknesses of each approach. We then propose a new rationale for technology foresight, which centers on its role in “wiring up” and thereby strengthening the national innovation system, before arriving at a number of conclusions. 相似文献

Abstract
Objectives
Genomic profiling in oncology is vital for determining eligible patients for mutation-specific targeted therapies. Use of commercial genomic testing has the potential to improve patient outcomes. Economic evaluations of in-house genomic profiling typically only include material costs while external commercial services include many other factors. Using non-small cell lung cancer (NSCLC) as an example, this study sought to characterize the unique challenges of costing testing services and their impact on results of economic evaluations. 相似文献167.

Many firms define their fiscal quarters as 13-week periods so that each fiscal year contains 52 weeks, which leaves out one or two day(s) a year. To compensate, one extra week is added every fifth or sixth year and, consequently, one quarter therein comprises 14 weeks. We find evidence of predictable forecast errors and stock returns in 14-week quarters, suggesting that analysts and investors do not, on average, adjust their expectations for the extra week. The ease with which 14-week quarters can be predicted, and expectations adjusted, suggests a surprising lack of effort on the part of analysts and investors. 相似文献

The US trade deficit has been growing for over 25 years and has been accompanied by enlarging freight rate differentials. While traditional models of trade have ignored these gaps assuming symmetry across all bilateral trade costs, the specific linkages between trade imbalances and international transportation costs have remained unexplored. Given the current trade policies, the implications arising from the endogenous adjustment of bilateral transport costs to policy-induced changes in the US trade deficit are of particular importance. To break new ground on this issue, we develop and estimate a model of international trade and transportation that accounts for the effects of persistent trade imbalances. The theoretical results are supported by our empirical analysis and indicate that bilateral transport costs adjust to a country's trade imbalance. The implication is that a unilateral import policy, for example, will cause spillover effects into the bilaterally integrated export market. To illustrate, we use our empirical results to simulate the anticipated spillover effect from the Chinese ban on waste imports. We find that China's ban and the projected 1.5% rise in the US trade deficit will lead to not only a 0.77% reduction of transport costs charged on US exports to China but also a 0.34% increase in transport costs on US imports from China. 相似文献

Performance‐based logistics (PBL) represents a strategy for sustaining complex systems following production. Despite several implementations, limited understanding exists regarding PBL and its implications. Research using grounded theory emerged a theoretical framework for PBL. Service dominant logic (SDL) is introduced as a theoretical lens for interpreting the results and understanding how trading partners achieve performance‐based outcomes. 相似文献
