In this article I argue that any analyses of the manifestations of urban natures within urban political ecology must center racial capitalism as a theoretical framework and account for how these manifestations, which rely upon the co-constitutive workings of race and nature, reproduce anti-Blackness and unequal productions of space. I engage urban frontier imaginative geographies as a lens through which to view the ongoing regimes of dispossession within the historical context of the founding of what is today known as Atlanta and the contemporary greening project of the Atlanta BeltLine. Race and nature intersect to function as instruments of power and converge in the spaces of the Atlanta BeltLine to (re)produce an urban green frontier.  相似文献

This paper investigates the signalling role of tax policy in promoting, or hindering, the ability of a monopolist to practise entry deterrence. We show that environmental policy can facilitate the incumbent firm's concealment of information from potential entrants, thus deterring entry, and yet entail welfare improvements. Furthermore, we demonstrate that entry deterrence is more likely to arise when environmental regulation cannot be rapidly revised across time if market conditions change (inflexible regimes) than when regulatory agencies can adjust environmental policy over time.  相似文献

This paper uses data from the 2000–08 waves of the German Socio‐Economic Panel dataset (SOEP) to assess the impact of deprivation in various life domains upon individual well‐being. Unobserved heterogeneity is controlled for by means of a random effects model extended to include a Mundlak term and explicit controls for the respondents' personality traits. The paper shows that people care about social comparison information in a number of domains, not just income. Using an equivalent income approach, the estimates suggest that a one standard deviation deterioration of the individual position in the income distribution is as important as a 33.5 percent decrease in own income. This monetary equivalent amounts to an income variation of between 25 and 43 percent when it comes to other deprivation domains, including durables, accommodation, health, and social relations. These results recommend that in the fight against deprivation more emphasis should be directed to these non‐monetary relevant dimensions.  相似文献

Consumer satisfaction with utility services has received increased attention from firms, consumer associations, regulators and governments since the 1990s. Evidence is mounting that consumers in specific socio-economic groups express lower satisfaction levels than their peers, at least, in some utility markets. Seeing this as part of their remit to protect consumer welfare, governments and international organizations are exploring possible demand-side policy responses with the intention of ameliorating lower satisfaction levels of these groups of consumers. However, more information on the precise relationships between satisfaction and consumers’ socio-economic background is required if policy is to be proportional and effective. This paper provides new empirical knowledge on this topic by contrasting consumers’ stated and revealed preferences for five utility services (electricity, gas, fixed and cellular telephony and Internet) across twelve European countries. We find strong evidence that consumers’ socio-economic characteristics matter: consumers with lower levels of education, the elderly and those not employed exhibit particular expenditure patterns on, and lower satisfaction levels with, some utility services. However, this relationship is uneven and depends on the socio-economic category and service in question. We conclude by highlighting five findings which may be of use to policy-makers when considering whether demand-side regulatory policies are required  相似文献

Emergence is a generic property that makes economies become complex. The simultaneous carrying out of agents’ intentional action plans within an economic system generates processes that are at the base of structural change and the emergence of adaptive complex systems. This paper argues that goals and intentionality are key elements of the structure of rational human action and are the origin of emergent properties such as innovation within economic complex systems. To deal with the locus and role of goals and intentionality in relation to the emergence of complexity we propose an analytical approach based on agents’ action plans. Action plans are open representations of the action projected by agents (as individuals or organizations), where the means (actions) and objectives (or goals) are not necessarily given, but produced by agents themselves.  相似文献

The Federal Open Market Committee (FOMC) of the U.S. Federal Reserve publishes the range of members’ forecasts for key macroeconomic variables, but not the distribution of forecasts within this range. To evaluate these projections, previous papers compare the midpoint of the range with the realized outcome. This paper proposes an alternative approach to forecast evaluation that takes account of the interval nature of projections. It is shown that using the conventional Mincer–Zarnowitz approach to evaluate FOMC forecasts misses important information contained in the width of the forecast interval. This additional information plays a minor role at short forecast horizons but turns out to be of sometimes crucial importance for longer-horizon forecasts. For 18-month-ahead forecasts, the variation of members’ projections contains information that is more relevant for explaining future inflation than information embodied in the midpoint. Likewise, when longer-range forecasts for real GDP growth and the unemployment rate are considered, the width of the forecast interval comprises information over and above the one given by the midpoint alone.  相似文献

We show that Approval voting need not trigger sincere behavior in equilibrium of Poisson voting games and hence might lead a strategic voter to skip a candidate preferred to his worst preferred approved candidate. We identify two main rationales for these violations of sincerity. First, if a candidate has no votes, a voter might skip him. Notwithstanding, we provide sufficient conditions on the voters’ preference intensities to remove this sort of insincerity. On the contrary, if the candidate gets a positive share of the votes, a voter might skip him solely on the basis of his ordinal preferences. This second type of insincerity is a consequence of the correlation of the candidates’ scores. The incentives for sincerity of rank scoring rules are also discussed.  相似文献

We consider a set of asymmetrically informed agents, where the information of each trader is susceptible of being altered when she becomes a member of a coalition. For this, we consider a general rule that depending on the coalition, a signal (or an information partition) is assigned to each member of the coalition. We set examples showing that Grodal’s (Econometrica 40:581–583, 1972), Schmeidler’s (Econometrica 40:579–580, 1972) and Vind’s (Econometrica 40:585–586, 1972) core characterizations of a continuum economy may fail in this general informational setting. However, under mild assumptions on the rule, we extend Schmeidler’s and Vind’s results to economies that allocate information to agents in each coalition according to the rule. We then focus on information mechanisms based on the size of coalitions and provide a general characterization result for the corresponding cores. Moreover, we pay close attention to the rule that assigns the shared information to each member of specific coalitions. We prove that the resulting cores are exactly the same independently of whether arbitrarily small or large coalitions share information.  相似文献

Although an increasing number of studies have demonstrated the short-term impacts of behavioral nudges to achieve public policy objectives, less is known about their longer-term impacts. In a randomized experimental design with over 100,000 households, we study the longer-term impacts of a one-time behavioral nudge that aimed to induce voluntary reductions in water use during a drought. Combining technical information, moral suasion, and social comparisons, the nudge has a surprisingly persistent effect. Although its effect size declines by almost 50% after 1 year, it remains detectable and policy-relevant six years later. In fact, the total reduction in water use achieved after the 4-month period targeted by the intervention is larger than the total reduction achieved during the target period. Further analysis suggests that the intervention works through both short-lived behavioral adjustments and longer-lived adjustments to habits or physical capital. Treatment effects are not detectable in homes from which the treated consumers have moved, which provides suggestive evidence that these longer-lived adjustments are mobile rather than incorporated into the housing stock. The persistence of the effect makes the intervention more cost-effective than previously assumed (cost drops by almost 60%). Nevertheless, water utilities may find this persistence undesirable if the nudges are intended to have only a short-run effect on demand during environmental emergencies.  相似文献

The franchisee is usually the most vulnerable part of the franchise relationship, and should therefore receive greater protection from the legal framework. In this regard, the franchisor's pre-contractual disclosure duty has evolved in its legal status. Whereas its original purpose was to ensure transparency in the market, it now serves to protect the franchisee. In this paper, we compare the franchisor's obligations established by the legal framework in Spain with those set out in the Model Law drawn up by The International Institute for the Unification of Private Law.  相似文献
