Economics of Environmental Management in a Spatially Heterogeneous River Basin

This article examines the allocative efficiency of water quality management activities to protect endangered salmonid species in a heterogeneous watershed in the Pacific Northwest. Using an integrated hydrological, biological, and economic modeling framework, the relative efficiency of alternative policy targets such as temperature reductions and enhanced fish populations is investigated. Results indicate that the heterogeneous nature of riparian conditions and stream morphology influence the choice of management activities. Localized effects of management efforts on temperature are important to achieve small temperature reductions. However, as the desired magnitude of temperature reductions increases, the cumulative (longitudinal) effects become more important, and management efforts in more distant reaches are more efficient than efforts nearer the point of monitoring. Finally, if the underlying objective is to increase fish populations, targeting conservation efforts based on physical criteria such as water temperatures or other total maximum daily load regulations may lead to substantial inefficiencies.     

How to Determine the Number of Relations Among Deterministic Trends

Hatanaka (1998a) showed that the number of relations between deterministic trends of different variables played an important role in empirical studies of macroeconomic theories. In the present paper two methods are presented to determine the number from the time-series data. The one investigates eigenvalues of the data covariance matrix on a parametric model of trends accommodating interrelationships. The other analyses OLS residuals on the basis of a looser concept of interrelated trends.

Cross-sectional regression analysis of return and beta in Japan

This paper investigates the relationship between return and beta using the cross-sectional regression method. Regression of return on beta without differentiating positive and negative market excess returns produces a flat relationship between return and beta. Taking into account the difference between positive and negative market excess returns yields significant conditional relationships between return and beta. The conditional relationship between return and beta is found to be in general better fit when the market excess return is negative than positive in terms of the goodness of fit measures such as R² and the standard error of the equation.     

Applying Multiattribute-Based Group Decision Making Techniques in Complex Equipment Selection Tasks

A practicing industrial engineer, even an experienced decision maker, needs help in the sense that there is a necessity to use more logical or analytical decision support tools, especially when dealing with control and instrumentation projects which are often worth millions of dollars. In this article we propose an algorithm which can support the process of group decision making relating to industrial automation, especially involving the selection of control and instrumentation equipment. The aim of this article is to look only at the algorithm's application and how it is applied. To this end, two test cases are used as examples: (1) selecting a local area network for installation in an academic environment; and (2) selecting an integrated control system for a real-world pulp and paper mill. Obtained results show that the algorithm leads to a satisfactory solution. A software form of the algorithm is being programmed for use as a decision support tool.     

Free Trade Agreements and Domestic Politics: The Case of the Trans‐Pacific Partnership Agreement

What is the role of domestic politics in facilitating or constraining a government's decision to participate in free trade agreements (FTAs)? This paper seeks to answer this question by focusing on the domestic politics in Japan over the Trans‐Pacific Partnership Agreement (TPP). In particular, we ask why the opposition to the TPP encompasses a much broader segment of society than is predicted by trade theorems. We show that a broader protectionist coalition can emerge through persuasion and policy campaigns by the elites, in particular, powerful protectionist interests expending resources to persuade the uncertain public.
