Feminist Ecological Economics and Sustainability

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning, development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship, equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.      

产业政策目标指向型城市人口规模研究

在分析影响城市人口发展因素的基础上,以义乌市为例,从劳动生产率、产业结构变化、高贡献率行业三方面论证了政策变动因素与城市人口发展的关系,提出产业政策目标指向型城市人口规模计算的研究框架和计算步骤。     

新农村建设必须重视农村的生态环境治理

农村生态环境的不断恶化已严重影响到中国农产品的竞争力,农业的可持续发展,农民的生活质量,农村的稳定。我们只有从新农村建设的大局出发,找出农村生态环境不断恶化的深层原因,进行综合治理,才能在稳定农村,发展农村的前提下,从根本上减少农村污染,保护农村生态,建设整洁乡村。     

区位决策视角下的集群生命周期分析

本文在对当前产业集群生命周期研究述评的基础上,将集群周期划分为成长、成熟、衰退、再发展四个阶段,并从企业区位决策的视角对集群生命周期的不同阶段进行分析。然后通过考察企业区位决策因子的动态变化和集群区核心产业的区外出口量增长率、主导产业的企业数量、修正后的空间基尼系数来对生命周期阶段进行划分,分析不同阶段下政府的决策行为。     

试论城市生命体中生活固体废弃物物流系统的完善

本文提出了城市生命体概念,指出城市生命体是个复杂的物质系统,并从新的角度来论述如何完善城市生活固体废弃物物流系统。     

企业文化对知识型员工组织承诺影响的研究

为了探讨提高知识型员工组织承诺的有效路径,文章针对现有研究中的一些不足,提出了不同企业文化导向对知识型员工感情承诺及继续承诺影响的研究框架,从理论上探讨了员工导向文化与任务导向文化如何对知识型员工组织承诺产生影响,以期为企业提高知识型员工的组织承诺提供理论指导.     

基于产品生命周期的物流系统动态规划研究

由于在产品不同生命周期阶段市场竞争具有不同的特征,因此企业采取的市场战略也有较大的差别。应用物流系统的动态评价方法,研究了有效支撑企业产品市场竞争战略的物流系统应该具有的关键性特征,并在此基础上分析了如何组织企业内外部的物流资源,使得物流系统成本最小化的动态规划问题。     

How to invest over the life cycle: Insights from theory

We analyse the state of the art in the field of life cycle portfolio choice, a recent strand of the literature on intertemporal portfolio selection. Life cycle models are designed to identify optimal savings and portfolio policies over the lifetime of investors. They can help to improve pension schemes by showing how these could be specifically tailored to the individual employee’s circumstances to overcome the ‘one-size-fits-all’ philosophy still prevailing in parts of the mandatory retirement savings system. To facilitate comparison, we first describe set-up, solution method and characteristic results for a basic model and then derive a general framework to classify existing contributions. We highlight the models’ strengths and weaknesses and assess their ability to resolve existing portfolio puzzles. Lessons from the literature are summarized and promising areas for further research identified. JEL classifications G11, D14, D91, H55     

Thermodynamics and process analysis for future economic scenarios

Economists are increasingly interested in forecasting future costs and benefits of policies for dealing with materials/energy fluxes, polluting emissions and environmental impacts on various scales, from sectoral to global. Computable general equilibrium (CGE) models are currently popular because they project demand and industrial structure into the future, along an equilibrium path. But they are applicable only to the extent that structural changes occur in or near equilibrium, independent of radical technological (or social) change. The alternative tool for analyzing economic implications of scenario assumptions is to use Leontief-type Input-Output (I-O) models. I-O models are unable to endogenize structural shifts (changing I-O coefficients). However, this can be a virtue when considering radical rather than incremental shifts. Postulated I-O tables can be used independently to check the internal consistency of scenarios. Or I-O models can be used to generate scenarios by linking them to econometric macro-drivers (which can, in principle, be CGE models). Explicit process analysis can be integrated, in principle, with I-O models. This hybrid scheme provides a natural means of satisfying physical constraints, especially the first and second laws of thermodynamics. This is important, to avoid constructing scenarios based on physically impossible processes. Process analysis is really the only available tool for constructing physically plausible alternative future I-O tables, and generating materials/energy and waste emissions coefficients. Explicit process analysis also helps avoid several problems characteristic of pure CGE or I-O models, viz. (1) aggregation errors (2) inability to handle arbitrary combinations of co-product and co-input relationships and (3) inability to reflect certain non-linearities such as internal feedback loops.     

Comprehensive assessment of patients with irritable bowel syndrome with constipation and chronic idiopathic constipation using deterministically linked administrative claims and patient-reported data: the Chronic Constipation and IBS-C Treatment and Outcomes Real-World Research Platform (CONTOR)

Abstract

Aims

To characterize a US population of patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) using CONTOR, a real-world longitudinal research platform that deterministically linked administrative claims data with patient-reported outcomes data among patients with these conditions.
