Is Decoupling Possible? Association between Affluence and Household Carbon Emissions in the Philippines

This paper investigates whether or not affluence is associated with carbon emissions at the household level in the Philippines. While there is abundant literature on this issue, limited studies are available for developing countries. We estimate household carbon emissions by combining input–output analysis with household expenditure. The results suggest that household carbon emissions are increasing non‐monotonically with a non‐existent turning point as households accumulate more assets. This is further supported by quintile estimates showing huge disparity in emissions between poor and rich households. Although household carbon emissions in the Philippines are not alarming, evidence suggests that it is likely households will lead a carbon‐intensive lifestyle as they become more affluent.     

Mapping EORTC-QLQ-C30 to EQ-5D-3L in patients with colorectal cancer

Aims: The primary aim of this study was to perform a mapping of the EORTC-QLQ-C30 scores to EQ-5D-3L for the SIRFLOX study; a large dataset of patients with previously untreated liver-only or liver-dominant metastatic colorectal cancer (mCRC). A secondary aim was to compare the predictive validity of existing mappings from EORTC-QLQ-C30 to EQ-5D-3L conducted in other cancers.

Methods and materials: Questionnaires (completed within 529 patients) were used in a linear mixed regression to model EQ-5D-3L utility values (scored using the UK tariff) as a function of the five function scores, nine symptom scores, and the global score from the EORTC-QLQ-C30 questionnaire. A Tobit regression was also performed. The mean EQ-5D-3L values for the SIRFLOX trial were calculated and compared with predicted EQ-5D-3L values derived using published mapping algorithms.

Results: The linear mixed regression model provided a satisfactory mapping between the EORTC-QLQ-C30 and the EQ-5D-3L, whilst the Tobit model did not perform as well. When utilities from the SIRFLOX data were calculated with previously published mapping studies, three out of five studies performed well (< 10% mean difference).

Limitations: The main limitation of the study was the lack of meaningful observations post-progression (67 paired observations). For this reason, this study was unable to test whether the mapping holds by disease stage. Additionally, although the study adds to the literature of mappings to the EQ-5D-3L, it is not known how results would differ using the EQ-5D-5L.

Conclusion: This study is the first of its kind in liver-only or liver-dominant mCRC, and mCRC in general. The mapping constructed showed a good fit to the data and provides practitioners with an additional mapping between EORTC-QLQ-C30 to EQ-5D-3L using a large dataset (529 patients, 707 paired observations). The study also confirmed the generalizability of mappings published by Proskorovsky, Kontodimopoulos, and Longworth to liver-only or liver-dominant mCRC.     

The impact of more complex family structure upon marital earnings premiums

This article employs a unique data set from Trinidad and Tobago to examine the impact of their more complex family structures upon marital earnings premiums. While family structure includes the single married couple structure common in the US, families in Trinidad and Tobago often have more adults living in the household, multiple married couples living in the same family, and multigenerational families. Marital premiums for family members most likely to invest in labor market production are estimated to increase with more complex family structure. In contrast, estimated marital premiums for members most likely to invest in home production are decreased with more complex family structure. Results suggest that specialization within the larger family help explain the existence of marital premiums.     

Dynamical clustering of exchange rates

We use techniques from network science to study correlations in the foreign exchange (FX) market during the period 1991–2008. We consider an FX market network in which each node represents an exchange rate and each weighted edge represents a time-dependent correlation between the rates. To provide insights into the clustering of the exchange-rate time series, we investigate dynamic communities in the network. We show that there is a relationship between an exchange rate's functional role within the market and its position within its community and use a node-centric community analysis to track the temporal dynamics of such roles. This reveals which exchange rates dominate the market at particular times and also identifies exchange rates that experienced significant changes in market role. We also use the community dynamics to uncover major structural changes that occurred in the FX market. Our techniques are general and will be similarly useful for investigating correlations in other markets.     

Risk and the Endogenous Economist: Some Comparisons of the Treatment of Risk in Physics and Economics

This is a talk, rather than a research or survey paper. Very little of what I say will be original, but I wish to stimulate discussion on a set of issues that arise from the nature of risk and that I consider problematic to our profession. The paper is not exhaustive of references and many of my arguments have been treated elsewhere. However, I suspect few will have approached the issues from the same starting point and assembled them in the same way.     

Inquiry and Review of Dependence in Marketing Channels: An Economics of Exchange Approach

This article extends the economics of exchange for bilateral monopolists to more general situations in marketing channels, that is, exchange between two members with alternatives, by incorporating insights drawn from power-dependence theory, interdependence theory, and the concept of switching cost. It proposes a framework of three factors of channel dependence and reviews the literature on the operationalizations of channel dependence based on the framework. This study concludes that the approaches used by channels researchers, explicitly or implicitly, more or less, capture the three factors of channel dependence. It also notices weaknesses in some approaches, including missing important aspects of a factor, possibilities of inflating or deflating channel dependence, and falling short of being a one-dimensional construct. The article finally draws conclusions and reports implications from the findings of this inquiry and literature review.     

Deterrence or Conflict Spiral Effect? Exercise of Coercive Power in Marketing Channels: Evidence from China

Purpose: The article aims to test the appropriateness of deterrence and conflict spiral models in marketing channels. Both models have been alternatively used as bases to explain firms’ power-related behaviors in marketing channels. However, the issue of the appropriateness of such an application in various contexts has not yet been addressed.

Methodology/approach: The authors develop the hypotheses based on deterrence theory and their alternatives based on conflict spiral theory. They gather data from 204 sales representatives of suppliers in China and use linear regression analysis to test their hypotheses versus alternatives.

Empirical findings: The data analysis offers supportive evidence for the deterrence logic but with unexpected results. By elaborating on the empirical results, the original assumption of deterrence theory, and the nature of interfirm relationship in marketing channels, the authors modify the deterrence model for research on power related-behaviors in the given context. The analysis implies a possible explanation for inconsistent findings in the literature regarding exercises of coercive power.

Originality/value/contribution: This article proposes a revised deterrence model that can interpret the empirical results with a consistent logic and better predict power-related behaviors in marketing channels.

Research limitations/implications: The research results may lack generalizability with respect to channel type and culture. It does not directly test the cognitive mechanisms that mediate the impact of power on its exercise. Researchers are encouraged to directly test the mediating constructs in other channels or countries.

Practical implications: The article includes some insights and implications for managers in understanding power structure and implementing influence strategies in business-to-business marketing.     

“Greening” the marketing mix: do firms do it and does it pay off?

Growing concern about the sustainability of the natural environment is rapidly transforming the competitive landscape and forcing companies to explore the costs and benefits of “greening” their marketing mix. We develop and test a theoretical model that predicts (1) the role of green marketing programs in influencing firm performance, (2) the impact of slack resources and top management risk aversion on the deployment of such programs, and (3) the conditioning effects that underpin these relationships. Our analyses show that green marketing programs are being implemented by firms, and we find evidence of significant performance payoffs. Specifically the results indicate that green product and distribution programs positively affect firms’ product-market performance, while green pricing and promotion practices are directly positively related to firms’ return on assets. In addition, industry-level environmental reputation moderates the links between green marketing program components and firms’ product-market and financial performance. Finally, we find that slack resources and top management risk aversion are independently conducive to the adoption of green marketing programs—but operate as substitutes for each other.     

Responses by Australian auditors to the global financial crisis

We examine the impact of the global financial crisis (GFC) on auditor behaviour in Australia. Using a sample of listed companies, we examine whether the GFC impacted the propensity of auditors to issue going concern modifications and increased audit effort as reflected in audit fees and audit reporting lag. Controlling for client characteristics, we find an increase in the propensity to issue going concern opinions during the period 2008–2009 compared with the period 2005–2007 and that Big N auditors responded to the GFC earlier than non‐Big N auditors. In relation to audit effort, we find evidence of increased audit fees during the period 2008–2009 compared with the period 2005–2007. There is, however, no evidence of increased audit reporting lags during the GFC.
