The WS framework provides a more complete account of the sustainability of a place than do sustainability indicators or conventional economic measures, such as gross domestic product. However, while many decisions that affect sustainability are made at regional and local levels, the abstract theory of WS was developed without explicit recognition of the porosity of geographic boundaries and the interdependencies of regions. In this paper, we make three contributions: a carefully reasoned defense of IW per capita as the WS criterion, an improved understanding of the relationship between mobility, labor productivity, and regional economic growth, and an empirical application to US counties that demonstrates the feasibility of empirical regional WS assessment by summarizing Jones' research. This analysis, extending the framework developed by Arrow and co-authors, accounts for more region-specific factors related to population, most notably the labor productivity component of health capital, and assesses IW per capita for all 50 states and 3108 counties in the US from 2010 to 2017. These improved methods revealed substantially more states and counties that were not WS relative to results using the Arrow et al. framework. The not-WS counties exhibited a distinct rural bias, as regional scientists have suspected but, nevertheless, the majority of rural counties were WS. Our work demonstrated that regional WS assessment is feasible, produces results that are consistent with prior expectations based on reasoning and empirical research, and has the potential to provide fresh insights into longstanding questions of regional development.

Over the last three decades, governments and international bodies have endorsed it in principle, and some of them have incorporated it into some areas of policy practice. Yet, PP is controversial in policy circles, public discussion and scholarly discourse. Here the PP literature is reviewed from the perspective of economics, where the tendency is to see theory and methods for rational decision-making under risk and uncertainty as well-established and risk management tools as well developed, and to view the PP with some circumspection. Following a brief introduction to PP concepts, history, applications, and controversies, I review and critique the standard economic approach to decision-making and risk management (here labeled ordinary risk management, ORM), identifying areas of incompleteness especially in the treatment of disproportionate and asymmetric threats. After reviewing some of the more prominent PP controversies in the scholarly literature, I suggest a conceptual framework for a PP that may withstand the major criticisms levied against the PP and make a unique and valid contribution to a decision and risk management arsenal that includes ORM. The framework relates the nature of the threat, the evidence, and the remedy indicated; and each of these elements is discussed in some detail. The scope of this PP is identified in general terms and distinguished from the quantity restrictions and regulatory safety margins that often serve as practical heuristics when ORM-based policies are implemented. Because the PP is clearly identified as a principle, I discuss the role of principles in policy design and implementation, and conclude with some suggestions as to how this PP could guide policy and management.

This chapter discusses the economics of land. There exists an ancient and persistent suspicion that land is not just any commodity or factor of production. Land has played a prominent role in the development of general economic theory, and it retains a special position in some current renditions thereof. There is recurrent debate whether any economic theory that treats land as nothing special can be valid. In the most general versions of the mainstream economic theory, land is treated as a factor of production, and the debate revolves around whether it is useful to reserve a special place for land in formulating the aggregate production function. Land and natural resource concepts remain important for many special purposes in economics. The Ricardian concept of economic rent remains durable and finds application in areas as diverse as land economics, location theory, and welfare change measurement. Agricultural economics, natural resource economics, urban economics, and regional economics are important areas of specialization within economics, and the classic concept of land, which is appropriately updated, plays an important role in each.

As the term neoinstitutionalist-heterodox suggests, this is a somewhat ill-defined group, the product of diverse intellectual influences. In order to place these economists and their contributions in perspective, it is necessary, first, to consider how concepts of property have been handled by earlier schools of economic thought and by contemporary noninstitutional economists. John Locke, Adam Smith, and the classical economists, the neoclassical economists, and the Chicagoans developed and sharpened an economic theory which found social virtue in the outcome of myriad independent decisions, each based on individual self-interest.' While self-interest was the motivating force behind individual decisions, individual ownership and control of resources were essential in order to permit the decentralization of allocative decisions. The competitive, laissez-faire, free enterprise system, which has served generations of mainstream economists as both a subject for study and a utopian ideal, requires the existence and wide distribution of private property. Not only does the laissez-faire system guarantee all manner of desirable

It is my purpose here to argue that the disagreements among us go deeper than mere disputes about priorities and tactics for doing resource economics, where all participants share a common vision of what resource economics is and should be. Rather, these disagreements extend beyond alternative conceptions of resource economics to fundamentally opposing methodologies, i.e., conceptions of knowledge and how to get it.

The grain price subsidies were eliminated which led to a substantial grain price increase. This paper examines the welfare changes associated with the grain policy reforms. All welfare measures unambiguously show that the consumers became worse off after the implementation of the grain policy reforms. More interesting, however, is the comparison between the rich and poor consumers. Evidence suggests that the rich lost more than the poor in monetary terms. Finally, the analysis shows that income inequality in China went down after the grain policy reforms.

Then, patients would have opportunity to try treatments, eventually settling on the one that works best for them. I examine this argument and offer three conclusions. (1) Patient heterogeneity – i.e. patients respond differently to a given treatment – creates the matching problem that motivates trial-and-switch strategies, and provides the ambiguity that drives the potential gains therefrom. However, trial and switch is not an unmixed blessing. (2) Ambiguity-seeking policy, over and above that provided by patient heterogeneity, would be accomplished by reducing sample sizes and/or replications in pre-approval testing. The mean level of acceptable risk could be maintained, but confidence limits would expand, increasing the risk to individual patients. In effect, this is just another proposal for less regulatory caution regarding treatment risks and more attention to risk-risk trade-offs, as suggested by the quality-adjusted life-years, QALY, framework. (3) The case for risk-neutral regulation of treatment safety should be taken seriously in cases of devastating and life-threatening afflictions. Otherwise it fails, most obviously in the case of treatments for relatively minor ailments, which treatments dominate shelf space at drug stores and advertising in the media.

Significant contributions began in the 1960's and 70's with conceptual insights into the causes for market failure and the design of appropriate policy responses. The practical orientation of the profession led to the development and application of analytical tools in a wide array of contexts. Prominent amongst these have been non-market valuation, market based policy instruments and the private sector provision of environmental protection. Interaction with natural and social scientists has been a feature. Cross fertilization has resulted to define emergent fields such as behavioural economics and ecological economics. Multidisciplinary endeavours have also grown in areas such as ecosystem service provision and integrated assessment modelling. These areas are likely to expand further with the ongoing contribution of core elements of the economics discipline.

Here we focus on the use of BT functions, a preferred method, and address an under-appreciated problem-variable selection uncertainty-and demonstrate a conceptually superior method of resolving it. We show that the standard method of value-function BT, using the full estimated model, may generate BT values that are too sensitive to insignificant variables, whereas models reduced by backward elimination of insignificant variables pay no attention to insignificant variables that may in fact have some influence on values. Rather than searching for the best single model for BT, Bayesian model averaging (BMA) is attentive to all of the variables that are a priori relevant, but uses posterior model probabilities to give systematically lower weight to less significant variables. We estimate a full value model for wetlands in the US, and then calculate BT values from the full model, a reduced model, and by BMA. Variable selection uncertainty is exemplified by regional variables for wetland location. Predicted values from the full model are quite sensitive to region; reduced models pay no attention to regional variables; and the BMA predictions are attentive to region but give it relatively low weight. However, the suite of insignificant RHS variables, taken together, have non-trivial influence on BT values. BMA predicted values, like values from reduced models, have much narrower confidence intervals than values calculated from the full model.

Not all of these values are reflected in markets, but all of them contribute in some ways to human wellbeing. Economic values of ES and natural assets relate in rigorous ways to the economic concept of welfare, which has been shaped by market logic. The advantage of this approach is that efficiency is defined consistently in the public sector, where it is reflected in cost benefit analysis (CBA) and in the private sector given efficient markets. The benefits and costs of many environmental initiatives have market and nonmarket dimensions, and methods of nonmarket valuation are introduced and discussed. None of this is free of controversy: market actors are often skeptical of nonmarket values, and CBA has critics protesting that market logic dismisses values arising from nonutilitarian ethical stances while paying too much attention to the preferences of the well-off. Price and value can be harnessed in payment programs and markets that incentivize enhanced provision of ecosystem services. Two such programs, the US sulfur oxides cap-and-trade program and the Australian experiments with conservation auctions, are discussed in some detail. These kinds of markets are intended to serve the public interest in providing ecosystem services efficiently, but they can succeed only if they also provide opportunities for cost-savings and/or business expansion for private operators large and small.
