DEVELOPMENT PRESSURES AND HERITAGE IN THE PERTH CENTRAL BUSINESS DISTRICT, 1950–90

This article examines the remaking of Perth's Central Business District (CBD) during the 1950–90 period. It traces the establishment of a modernist development ethos in Perth's planning, outlines the inadequacy of the City's planning regulations, and analyses the impact on St George's Terrace, the city's main commercial thoroughfare. The City Council was largely incapable of restraining excessive development and the extension of its system of plot ratios encouraged manipulation to increase the height of developments. Several important historic buildings were demolished because there were no legal means of safeguarding the city's heritage until 1990.

石化行业中的经验曲线效应

经验曲线是美国著名波士顿咨询公司开拓的管理预测概念和工具之一，回顾经验曲线的起源及发展，总结了有关石化行业中的经验曲线效应现象，即：典型的大宗化工产品的固定成本的长期趋势存在明显的双倍斜率约为25％的经验曲线效应；同时单位固定资产投资也存在着双倍斜率为25％～63％的经验曲线效应。指出经验曲线是预测大宗化学品固定成本和投资长期趋势的一个有效实用的工具，并就国内应用经验曲线时应注意的问题及想法进行了探讨。     

Heterogeneous returns to chemical fertilizer at the intensive margins: Insights from Nepal

Increased fertilizer use is considered important for agricultural development in low-income countries. Promoting increased use of chemical fertilizer by lowering its price may be ineffective if demand is price inelastic. In theory, the price elasticity of demand depends on the returns to its use, but the evidence is scarce. Furthermore, while returns are often estimated for small changes in chemical fertilizer use, returns to larger changes in its use (intensive margins) are less understood. Through the inter-zonal comparisons in Nepal, we provide indicative evidence that greater returns to chemical fertilizer are associated with greater price elasticities of demand. Moreover, the evidence suggests that returns at the intensive margins, rather than returns to small changes, may largely account for inter-zonal differences in returns to chemical fertilizer within Nepal. The results suggest that better understanding the returns at the intensive margins is critical for effective agricultural inputs policies in developing countries.     

Toxic chemical releases and idiosyncratic return volatility: A prospect theory perspective

We investigated whether and how firms’ toxic chemical releases (TCRs) affect idiosyncratic return volatility (IRV) using a prospect theory lens. Utilising a large sample of US public listed firms over the period 2001–2018, we find a significant and positive association between TCRs and IRV, suggesting that firms releasing more toxic chemicals have higher IRV. Additional analyses show that a positive association between TCR and IRV is more evident among firms with (i) high revenue, (ii) lower financial constraints and (iii) fewer environmental violations. A further test also suggests that a positive association between TCRs and IRV is contingent on political leadership ideology and market states. Our results remain consistent with weighted TCRs, IRV based on the Fama–French three-factor model, fixed-effect two-stage least square estimator (FE-2SLS), and other robustness checks. These findings shed light on the role of equity markets as a driver for capital-intensive pollution abatement activities and enhanced compliance with environmental laws, standards and best practices.

“Standards” as a Service Marketing Tool

Abstract

Standards have the potential to be a significant tool in the marketing of services, just as they have been in the marketing of products. Ranging from regulatory to voluntary, product-based to producer-based, standards can increase the competitive position of a product by reducing customer uncertainty. However, the lack of a framework for understanding and designing standards has limited their application in service industries.

Examination of existing standards suggests a framework of five key dimensions. Through the example of chemical management services (CMS) we show how this can be done, resulting in three options for the CMS industry. Using this framework as a guide, other service industries can determine if a standard would provide significant competitive advantage and, if so, design the optimal standard for their market conditions.     

能源化工产业集聚水平实证研究--基于E-G指数的视角

本文采用E-G指数,从产业空间、时间和地理空间等维度测度中国2005-2012年能源化工产业集聚状况。在产业内部,上游行业集聚水平非常高,中游和下游行业集聚现象不明显;在时间上,能源化工产业集聚水平在全国范围内呈缓慢上升趋势;在空间分布上,西部地区上游行业集聚程度非常高,部分行业在东部、中部和东北呈现集聚现象,但并没有显现一定的规律。
