Export agriculture offers potentially high returns to smallholder farmers in developing countries, but also carries substantial market risk. In this article we examine the intertemporal welfare impact of the timing of a farmer's entry into the export pineapple market in southern Ghana. We examine whether farmers who never cultivated pineapple are better or worse off than farmers who decided to adopt pineapple earlier or later relative to their peers and experienced a significant adverse market shock several years prior to our endline survey. We use a two‐stage least squares model to estimate the causal effect of duration of pineapple farming on farmer welfare. Consistent with economic theory, we find that earlier adoption of the new crop brings greater welfare gains than does later uptake. But we find that the gains to later uptake of pineapple—just before the market shock—are small in magnitude, just 0.1 standard deviations of a comprehensive asset index, indicating that the gains to adoption may be precarious and depend on the context, in particular on the severity of prospective market shocks.  相似文献

Limited opportunities for crop switching and lengthy preharvesting periods make the plantation sector particularly vulnerable to climate change. Surprisingly, however, the economic consequences of climate change on plantation crops are seldom analysed. Drawing on a unique primary panel data set from a representative cross section of 35 tea estates in Sri Lanka over the period 2002–2014, this study implements a structural model of estate profit maximisation to estimate the elasticity of labour demand with respect to different components of weather. Results indicate a negative relationship between labour demand and rainfall in the south‐west monsoon, the north‐east monsoon and the second inter‐monsoon. A positive relationship is found between labour demand and rainfall in the first inter‐monsoon. Overall, predicted changes in rainfall by 2050 are anticipated to reduce labour demand by approximately 1,175,000 person‐days per year across Sri Lanka's tea plantation sector. This is likely to have considerable social and welfare implications, particularly for the Indian Tamil women who comprise the majority of the sector's workforce.  相似文献

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

John Dewey frequently praised Henry George, author of a plan to confiscate land values with a “single tax.” Scholars have failed to account for Dewey's support of George. Some have argued that it should not be taken seriously because it is at odds with their interpretation of Dewey's philosophy. This article demonstrates that Dewey perceived the socialization of land values as an essential step toward creating a true democracy. Furthermore, Dewey's interest in George was not an aberration; it was exemplary of his faith in ideology, theory, and transformative social policy. Despite contentions to the contrary, pragmatists of the early 20th century never emphasized skepticism, moderation, or rote empiricism. In fact, Dewey embraced the philosophy of Henry George as a general theory of history of society. During the Great Depression, Dewey attacked the piecemeal reformism of the New Deal in favor of the comprehensive vision of Henry George.  相似文献

At the beginning of the 20th century, Vancouver obtained international acclaim as a “single‐tax” city. Supporters claimed that land value taxation was responsible for the spectacular growth of the city. Even critics believed that it had produced a building boom and declining rents. Yet, over several decades, the system was scaled back and ultimately ended in 1984. This article argues that the property tax revolt can be understood with Mancur Olson's model of collective action. Property owners are better organized than other parties impacted by housing policy because they have financial resources and a salient economic concern in housing. Thus, the special interests of property owners in higher values and unrestricted use prevailed over the interests of tenants and prospective buyers. While the property tax revolt was often articulated in the progressive language of ability to pay, when confronted with progressive counterarguments, it collapsed into explicit arguments for rent‐seeking.  相似文献

The growing body of literature on “accessible tourism” lacks a critical scholarly debate around its specific language use and nomenclatures. To fill this gap, this paper provides a first examination of language. Language provides a unique capability to resist, strengthen and reframe identities of individuals and groups, yet can also reinforce, weaken and perpetuate dominant worldviews of disability. A content analysis examined previous accessible tourism literature with results illustrating that diversity exists amongst the varying terminologies adopted by scholars. Terms were employed loosely, inconsistently and interchangeably, euphemistically with erroneous understandings and nuances. The paper concludes with critical discussion about the power of researchers to (re) produce oppression through language that maligns and misrepresents, or to (re) conceptualise and (re) construct the world we live in with liberating language that facilitates positive social change.  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

This article introduces the special issue on the intersection between industrial organization and healthcare economics. This intersection has received increasing research interest, growing from 2% of the industrial-organization literature in 1991 to 6% in 2016. We describe the nine included articles, which cover a range of healthcare markets that include hospital services, insurance, and pharmaceuticals.  相似文献

The lead user concept has attracted a lot of attention from scholars and practitioners alike. However, different studies apply different conceptualizations and measures of the lead user construct. Such variation in measurement of the construct make it almost impossible to consolidate findings from prior lead user research, which in turn hampers the accumulation of insights on the concept itself. This is also a challenge with respect to managerial practice: due to different interpretations of the concept, managers and R&D staff find it difficult to identify lead users for workshops and cooperation, and companies are often unable to transfer results from lead user projects to new product and business development. As a result, they only rarely repeat their work with lead users. The aim of this article is therefore to provide some thoughts and guidance on the conceptualization and measurement of the lead user construct.  相似文献
