This paper investigates the implementation of “one village, one product” (OVOP) in four peri‐urban villages in China's Yangtze River Delta. China's agricultural transformation, including the introduction of new corporate actors and the growing pressure of market discipline, has challenged the relevance of villages in the organization of agricultural production. In response, village cadres in thousands of Chinese villages have used OVOP to transform their villages into agro‐industrial firms and re‐exert their control over the agricultural surplus, echoing earlier examples of village corporatism. Rooted in agricultural specialization, OVOP encompasses a diversity of strategies for the production of locality‐based value. I disaggregate these strategies into four sociospatial dimensions that comprise locality—place, network, territory, and scale. Place‐based branding is the dominant strategy, but village cadres also pursue complementary sociospatial strategies to ensure their control over the realization of the brand's value and reconstitute their redistributive and administrative powers. 相似文献

This paper uses a natural experiment—the Super Bowl—to study the causal effect of advertising on demand for movies. Identification of the causal effect rests on two points: 1) Super Bowl ads are purchased before advertisers know which teams will play; 2) home cities of the teams that are playing will have proportionally more viewers than viewers in other cities. We find that the movies in our sample experience on average incremental opening weekend ticket sales of about $8.4 million from a $3 million Super Bowl advertisement. 相似文献

Consumer sorting and hedonic valuation of wine attributes: exploiting data from a field experiment 下载免费PDF全文
Christopher R. Gustafson Travis J. Lybbert Daniel A. Sumner 《Agricultural Economics》2016,47(1):91-103
This article uses a novel experimental approach to measure consumer willingness to pay (WTP) for wine attributes. We invited customers of a local supermarket who had selected a bottle of wine to purchase to participate in a valuation experiment. Integrating their original wine choice into the experiment, each participant evaluated six alternative wines, generating a rich set of data on willingness to pay and consumer characteristics. The data from the experiment allow us to compare standard shelf price‐based wine attribute valuation estimates with estimates using WTP data and an increasing amount of information about individual consumers. The full model employs individual fixed effects to estimate WTP parameters without bias from consumer sorting or supply side influences. Our WTP estimates for wine attributes differ markedly from previous attribute value estimates. Consumers in our sample display clear and stable preferences for wine varieties, but less clear preferences for appellations. Our results suggest caution is needed in using market prices to estimate parameters of the consumer valuation function for product attributes. 相似文献

Managers responsible for novel industrial products seek to identify their most productive customers promptly, as a basis for deployment of marketing and development resources. Using a trial-and-adoption model, based upon invoice data from sales of novel industrial products over a five-year period, Richard Cardozo, David Smith and Madhubalan Viswanathan show that initial interpurchase interval (the time from initial purchase to first repeat purchase) identifies high-volume customers, no matter when they first purchased. In addition to demonstrating the usefulness of a trial-and-adoption model in analyzing purchases of novel industrial products, this study also describes for the first time four distinct purchase patterns for novel industrial products. 相似文献

Kremer and Snyder (Q J Econ 130:1167–1239, 2015) show that demand curves for a preventive and treatment may have different shapes though they target the same disease, biasing the pharmaceutical manufacturer toward developing the lucrative rather than the socially desirable product. This paper tightens the theoretical bounds on the potential deadweight loss from such biases. Using a calibration of the global demand for HIV pharmaceuticals, we demonstrate the dramatically sharper analysis achievable with the new bounds, allowing us to pinpoint potential deadweight loss at 62% of the global gain from curing HIV. We use the calibration to perform policy counterfactuals, assessing welfare effects of government policies such as a subsidy, reference pricing, and price-discrimination ban. The fit of our calibration is good: we find that a hypothetical drug monopolist would price an HIV drug so high that only 4% of the infected population worldwide would purchase, matching actual drug prices and quantities in the early 2000s before subsidies in low-income countries ramped up. 相似文献

Recognising the potential conservation impact, zoos regularly ask their visitors to undertake pro-wildlife behaviour. This paper presents the results of two studies undertaken to address the question: how often during a visit should visitors be asked? Study 1 sought to a) determine individuals' personal thresholds and b) the point where the number of different behaviours requested began affect visitors' experiences. Study 2 sought the same, but focused on requests for the same behaviour. Results suggest that few respondents' personal thresholds were crossed (2.5% in Study 1 and 9% in Study 2). In neither study did many respondents (2.5% in Study 1 and 2.8% in Study 2) feel that the number of requests negatively affect their overall zoo experience. While there are caveats, we conclude that there appears little cause for concern about asking zoo visitors on multiple occasions to act in support of wildlife. Indeed, such requests may improve experiences. 相似文献
