Intimate relationships are foundational to farm viability. They affect how farmers share tasks, earn income, and access land, yet the role of sexuality and heteronormativity in agriculture remains understudied. Furthermore, queer people are largely ignored as potential farmers by the sustainable agriculture and lesbian, gay, bisexual, and transgender (LGBT) movements. I document the lived experiences of queer farmers, an underresearched group, through participant observation and interviews with 30 sustainable farmers of various genders and sexualities in New England. I use a queer perspective to illuminate sexualized and heteronormative patterns in sustainable agriculture. Whereas the perception of rural heterosexism can discourage queer participation in agriculture, queer farmers faced less overt heterosexism than they expected. However, they did experience heterosexism particular to sustainable agriculture, and confronting it might jeopardize relationships important for economic and environmental sustainability and land access. Some farmers were attracted to sustainable agriculture for reasons specific to gender, sexuality, and anticapitalist values. I argue that sexuality and heteronormativity are embedded in farmer recruitment, retention, and land acquisition, which are critical for the transition to sustainable agriculture. I offer the sustainable agriculture movement a lens for envisioning alternatives for farm families, homes, and workplaces. 相似文献

This paper develops a generalized Roy model with human capital accumulation, moral hazard, and career concerns. We identify and estimate the model with a large panel that matches data on publicly listed firms to information on their executives. The structural estimates obtained are used to decompose the firm‐size pay gap. We find that although total compensation and incentive pay increase with firm size, certainty‐equivalent pay decreases with firm size. In larger firms, and for more highly ranked executives, weaker signal quality about effort results in higher risk premiums. This risk premium accounts for roughly 80 percent of the firm‐size gap in total compensation. Larger firms are also willing to pay more than smaller ones to attract executives. Finally, the estimated coefficients on human capital accumulation from formal education and experience gained from different firms are individually significant, but their collective effect on firm‐size pay differentials nets out. 相似文献

In recent supply chains, often operating multiple delivery modes such as standard freight shipping and air is an effective way of addressing both delivery lead time uncertainties and service rates. We propose a model on how to optimally operate multiple delivery modes. We consider a serial supply chain and an expediting option from intermediate installations to the downstream of the chain. The goods move stochastically among the installations and the system faces a stochastic demand. We identify systems that yield simple optimal policies, in which both regular ordering and expediting follow a variant of the base stock policy. Expediting allows the system to be leaner due to the reduced regular order amount. In addition, we provide managerial insights linking expediting, base stock levels, and expediting costs based on analytical and numerical results. 相似文献

Explaining Diversities in Age-Specific Life Expectancies and Values of Life Saving: A Numerical Analysis 总被引:1,自引:0,他引:1
To what extent can life protection account for observed diversities in age-specific life expectancies across individuals and over time? We provide answers via calibrated simulations of a life-cycle model where life’s end is stochastic, and age-specific mortality hazards are endogenous outcomes of life protection, set jointly with life insurance and annuities. Our model links mortality hazards and values of life saving (VLS) as “dual variables”, and offers new insights about the measurement of VLS. Life protection is estimated to account for non-trivial portions of observed levels and inequalities in life expectancies and empirical estimates of VLS by age and education, and over time. 相似文献

The cooperatives are too economically oriented to be included in the non-profit sector and too socially oriented to be considered as an economic for-profit organization. These “enfants terribles” are wholly depersonalized. They represent a broader phenomenon, going beyond the dominant global economy. As such, cooperatives are seen as a model based on dual components, an economic and a social. Here lies the source of the incompatibility between the hegemonic economic paradigm and an organizational rationale claiming to be based on the co-existence of two features, the social and the economic.Therefore, this article supports the idea of non-profit economy, the cornerstone of the social economy but facing outward offering competing goods and services which can facilitate the market economy and mitigate the tendency towards oligopoly. 相似文献

Newcomb's paradox rests on two arguments one appealing to the principle of maximizing expected utility and one appealing to dominance in order to generate conflicting recommendations in certain kinds of choice situations. In my essay, I argue that the applications of the principle of maximizing expected utility and of the dominance principle are both fallacious and that the specification of the decision problem is too indeterminate to render a verdict between the two options considered. I also show that if Nozick's case for invoking the dominance principle is taken seriously, it leads to contradictions. 相似文献

As a sexually transmitted disease, AIDS spreads along social networks; consequently,it is reasonable to propose to utilize these networks in teaching people to avoid practices that put them at increased risk of contracting AIDS. Most obviously, homosexual men are both at relatively high risk of contracting AIDS, and in many urban areas have well crystallized community structures and high social connectivity. We present evidence suggesting that using such social networks can have the unanticipated consequence of reaching a set of men who are at relatively low risk. Evidently, there is great unobserved heterogeneity among the population in terms of risk, and while this heterogeneity is not captured by conventional measures of risk behavior, it is closely linked to network processes. 相似文献
