Assessing costs and benefits of pest management on forested landbases in eastern and western Canada

To assist pest management planning, the Canadian Forest Service developed the Spruce Budworm Decision Support System (SBW DSS), which quantifies the timber supply impacts of protecting stands against spruce budworm (Choristoneura fumiferana Clem.) defoliation. We incorporated protection costs and timber product values in this system to evaluate economic aspects of spruce budworm control. The analysis allows pest managers to evaluate the degree to which the traditional volume protection priority objective corresponds to three economic criteria, namely the volume protected per dollar protection program cost, the benefit–cost ratio of the protection program, and the net present value of the protection program. Twelve alternative spruce budworm protection strategies were analyzed on Crown License 1 in New Brunswick and Prince Albert Forest Management Area (PAFMA) in Saskatchewan, based on a number of protection program extents and intensities. For both landbases under base-case market conditions, the largest, most intensive protection scenario provided the highest amount of volume saved and net present value (at 3.94 Mm³ and $39.98 M for PAFMA, and 4.04 Mm³ and $41.49 M for License 1, respectively) while smaller, less-intensive programs provided the highest benefit–cost ratios and volume protected per present value dollar of protection cost (at 8.22 and 0.52 m³/$ for PAFMA, and 10.26 and 0.65 m³/$ for License 1, respectively). Sensitivity analysis on product values and protection costs revealed that smaller, less-intensive programs could also produce the highest net present values when costs are higher and/or product values lower. These results highlight the conditions under which pest managers should consider deviating from their traditional strategy of maximizing volume saved to one that maximizes the economic returns of protection.     

Endogeneity and the relationship between board structure and firm performance: a simultaneous equation analysis for the Athens Stock Exchange

The main goal of this paper is to examine the relationship between the three most important characteristics of the board of directors with firm performance. More specifically, we investigate whether the independence of the board, the leadership structure and the board size, are exogenous determinants to the firm's performance, using a simultaneous equations framework. Our database is composed of firms quoted in the ASE, starting from 146 observations in 2000 and ending with 232 firms in 2006. The findings suggest that the board independence and the leadership structure do not affect the firm performance. On the other hand, an inverse relationship between board size and firm performance is observed. Copyright © 2010 John Wiley & Sons, Ltd.     

Problems of Emergency Arbitration

This paper explores ethical burdens facing the economics profession which are associated with epistemic features of economic practice. Economists exert power over those they purport to serve by virtue of epistemic asymmetry between themselves and others, i.e., the intellectual monopoly they enjoy over a vitally important body of knowledge. But they also face the problem of epistemic insufficiency, which implies that they may do substantial harm as they try to do good. The paper explores the ethical entailments of the epistemic features of economics, and argues that managing the ethical challenges requires a new field of inquiry, the field of professional economic ethics, and not just a code of conduct.     

Consumer Economics and Family Economics: The Charge,the Response

A “Timeless” charge to consumer economics and family economics is identified. In light of the charge, the area is examined with particular emphasis on scholarly activity. It is suggested that scholarship in the area is diffuse and often addresses parts of issues. This creates concerns as to whether the historical charge is being met.     

Inflation und Schuldenabbau

The European Central Bank (ECB) recently announced its willingness to do whatever is needed to save the euro. This has raised the question whether such a role of the ECB must lead to higher rates of infl ation. Under current recessive macroeconomic conditions in the eurozone, the ECB’s expansionary monetary policy will not lead to higher infl ation. On the contrary, there is a serious danger of defl ation. Higher infl ation would likely occur only if a permanent stabilisation function were assigned to the ECB. Yet historical examples show that mistakes can be made. During the stagnation in Japan, US economists heavily criticised the Bank of Japan’s timid monetary policy response. But in some sense, current Fed policy seems to be a direct copy of that strategy, caused by uncertainty about the proper communication channel. An infl ation tax could help to bring down the mounting public debt in the wake of the fi nancial crisis, but higher wealth taxes have more transparent distributional effects.     

Not Only Gender: More on Debating Markets

The paper by Gudeman and Gudeman on the nature of computer-mediated-communication (CMC) is a valuable contribution. This comment argues that they neglected one important aspect affecting CMC, namely ideology, and suggests that the ''Debating Markets'' exchange had long-term negative impacts on Femecon.     

Advanced models of quality function deployment: a literature review

In this paper, a literature review conducted to study the characteristics of advanced models of quality function deployment (QFD) that have appeared in the literature arena is reported. QFD technique emerged in Japan in the 1970s. QFD has been proving to be a powerful tool that can be used for translating the voice of customers into technical languages. Yet from the beginning of this century, researchers began to point out the need to refine, modify and improve the features of QFD technique. In order to fulfil this need, few researchers brought out several advanced models of QFD. While conducting the literature review reported in this paper, six types of such advanced models of QFD were identified in the literature arena and their characteristics were studied. The result of this study revealed that the procedural and computational complexities are least in the case of an advanced model called total quality function deployment (TQFD). TQFD technique replaces the complex computations involved in applying conventional QFD technique with simple ratings. Besides the formation of teams to translate the voice of customers into work instructions ensures the quick reactions to the customers’ desires in the actual field of implementation. In this background, at end of this paper, it is suggested to adopt TQFD for implementation in traditional organizations in which the prevalence of adequate education for adopting complex procedures is found to be least.     

Nowcasting the French index of industrial production: A comparison from bridge and factor models

Governments and central banks need to have an accurate and timely assessment of indicators for the current month, as this is essential for providing a reliable and early analysis of the current economic situation. The index of industrial production (IIP) is probably the most important and widely analyzed monthly indicator, given the relevance of the manufacturing activity as a driver of the whole business cycle. This paper presents a series of models conceived to forecast the current French monthly IIP, based on regression models and dynamic factor models. The combination of these two approaches allows selecting economically relevant explanatory variables among a large data set. In addition, a rolling forecast study is carried out to assess the forecasting performance of the estimated models, using predictive ability and model confidence set tests. This latter allows getting several models displaying equivalent forecasting performance and therefore gives robustness to the forecasting exercise rather than to base the forecasting analysis only on one model.     

Economic efficiency of synthetic motor fuels from natural gas

In this paper we study alternative ways to meet the demand for motor fuels growing in connection with the inevitable rise in oil prices over the next decade or two. One of these is to use natural gas as a motor fuel and as a raw material for synthetic motor oils. Calculation results of the comparative effectiveness of the gas-to-liquids (GTL) technology of motor fuel production from natural gas are presented. It is shown that these technologies look economically promising in countries, which have their own sources of natural gas, especially in small and remote gas fields.     

ACCI Memorial Paper: The Scholarly Legacy of E. Scott Maynes

This paper honors E. Scott Maynes, who died on June 24, 2007 and had been a professor emeritus in the Department of Policy Analysis and Management at Cornell University.
