REPORTING GUIDELINES FOR META-ANALYSIS IN ECONOMICS

Meta-analysis has become the conventional approach to synthesizing the results of empirical economics research. To further improve the transparency and replicability of the reported results and to raise the quality of meta-analyses, the Meta-Analysis of Economics Research Network has updated the reporting guidelines that were published by this Journal in 2013. Future meta-analyses in economics will be expected to follow these updated guidelines or give valid reasons why a meta-analysis should deviate from them.     

Environmental Impact Assessments from a Business Perspective: Extending Knowledge and Guiding Business Practice

Economic growth and development remain embedded in the very core of our current international economic system and the so called “material economy”. However, depleting natural resources and environmental degradation, which now threaten the well-being of future generations, has challenged this premise, and placed sustainable development as a necessary objective of business activity and expansion. Environmental impact assessments (EIAs) have emerged as a key tool for governments, businesses, and NGOs to manage the negative impact of their activities on the environment. Businesses in particular play a key role in averting or mitigating current environmental trends given that the economic growth they have stimulated has serious consequences for both the environment and social well-being. However, research on the use of EIAs has been conducted mostly from a governmental perspective producing a clear gap between research development and business (corporate) practice. To bridge this gap in knowledge, we develop a new EIA process tailored to real world business constraints and provide a range of propositions which we hope will stimulate future research efforts toward understanding and guiding how businesses integrate environmental issues into their decision-making processes.     

A Multi-Attribute Negotiation Support System with Market Signaling for Electronic Markets

Despite the rapid growth of technology and Internet-based markets, many of the current systems limit themselves to price as the single dimension variable and offer, if at all, only minimal negotiation support to the consumer. In the real world, commercial transactions take into account many other parameters both quantitative and qualitative such as product quality, speed, reputation, after sales service, etc. This paper discusses how these multiple attributes can be captured to augment standard negotiation processes in order to support electronic market transactions. Using a combination of utility theory and multicriteria decision-making, we propose heuristic algorithms to discover potential trades. In addition, the approach is included within a larger framework that incorporates market-signaling mechanisms. This not only allows for the systematic evolution of negotiation positions among buyers and sellers but can ultimately lead towards improving both market transparency and efficiency. To illustrate the multiple criteria model coupled with the dynamic market signaling framework, we report in this paper the implementation of a Web-based clearinghouse that serves the real estate market.     

India’s Color Complex: One Day’s Worth of Matrimonials

Lighter skin complexions may function as a form of capital, particularly for women, in marriage markets. The existence of a preference for light skin for marital partners is an index of the presence of colorism or color bias in a given society. This paper reports on a detailed examination of marital advertisements that appeared in India’s Sunday Times on a single day in March 2013. It asks how often skin shade is mentioned in the advertisements placed among those seeking grooms and those seeking brides, how those mentions are distributed by the reported age of the prospective marital partner, and the type of language used to describe the individual’s complexion. The study finds that skin shade is described far more often in advertisements placed by prospective brides or their families than prospective grooms or their families, and, whenever complexion is mentioned, the possession of lighter skin shades.     

An infinite depth dam with Poisson input and Poisson release

Abstract

In this paper the content Z(t) of a dam where Z(t) ε( - ∞, h], h an arbitrary constant, is studied. Inputs to the dam form a sequence of i.i.d. r.v.'s and occur according to a Poisson process with parameter λ > 0 while releases from the dam form a sequence of i.i.d. r.v.'s and occur according to a Poisson process with parameter μ > 0. The Laplace transform of the process Z(t) is derived and expressions for the moments are given. It is shown that Z(t) has a nondegenerate limiting distribution, as t -- ∞, if average inputs per unit time exceed average releases per unit time.     

Risk management and governance:: a post-normal science approach

In this essay we consider the problems of risks and governance in the light of three well-known examples: the ‘Seveso' accident involving dioxin; the BSE epidemic; and the licensing of genetically modified maize. These form a natural progression, from hazards that are ‘classical', manageable mainly by ‘applied science', to those that are totally post-normal. The new hazards typified by genetically modified maize, but including many others such as untested toxic chemicals, pose serious challenges to governance. The erosion of trust in the established institutions could lead to paralysis of innovation and also of government.
