Synthesis of Complex Criteria Decision Making: A Case Towards a Consensus Agreement for a Middle East Conflict Resolution

The title of this paper reflects both the process and the outcome of the current undertaking. Frustrated with the current state of the Middle East but encouraged by earlier attempts at modeling complex problems, the authors participated in a panel discussion assembled to address the conflict and propose a possible road-map to peace. However, the participants of this project did not come to a single course of action that will result in peace in the Middle East but did reach a consensus agreement about a resolution that needs to be managed. This paper explores the process, the outcome and the factors that influence the decision as well as potential pitfalls. The Analytic Network Process (ANP), a well known multicriteria decision making approach, applied frequently in recent years to examine conflicts around the world, is used in this analysis. It provides a framework for synthesizing judgments on the diverse aspects of the problem represented in the structure of the decision. It pieces together these judgments in a holistic and logical way.     

Mixed Ownership, Unemployment, and Welfare for a Developing Economy

This paper considers the employment and welfare effects of mixed ownership via partial privatization of state‐owned enterprises for a developing economy. An increase in the private ownership lowers the production and, hence, worsens urban unemployment in the short run. However, in the long run, capital moves to the rural region, alleviating the problem of urban unemployment. The employment effect can have a positive contribution to social welfare in the long run.     

Outside monitoring and CEO compensation in the banking industry

We hypothesize that CEO compensation is optimally designed to trade off two types of agency problems: the standard shareholder-management agency problem as well as the risk-shifting problem between shareholders and debtholders. Analyses in this setup produces two predictions: (1) the pay-for-performance sensitivity of CEO compensation decreases with the leverage ratio; and (2) the pay-for-performance sensitivity of CEO compensation increases with the intensity of outside monitoring on the firm's risk choice. We test these two hypotheses for the banking industry where regulators and nondepository (subordinated) debtholders provide outside monitoring on the risk choice. We construct an index of the intensity of outside monitoring based on three variables: subordinated debt rating, non performing loan ratio and examination rating assigned by regulators. We find supporting evidence for both hypotheses.     

Developing breakthrough products: challenges and options for market assessment

Competitive pressures and market forces are augmenting the importance of product innovation as a source of competitive advantage. Key drivers underpinning market success have the capacity to develop the “right” products for the “right” customers, using the “right” channels, with a shorter development cycle than competitors. But when breakthrough products (BTPs) are involved, how do we sort out what is “right”? How do we identify customers' future requirements when the technology platforms are still unfolding, products are still in development and customers lack experience with the product? Traditional product development market research techniques are problematic since they assume the customer has historical experience with products similar to those being created. The objective of this paper is to raise the awareness of the OM community with the strengths and weaknesses of existing methodologies for developing and introducing innovative products to market. Further, it suggests promising future directions for both practice and research when BTPs are involved. This is important because of the central role OM plays in managing the success of the BTP development process.     

Manufacturing and the Trade Balance

When the world shifted to the regime of flexible exchange rates after 1970, economists expected that large trade imbalances would soon disappear. Instead, such imbalances not only persisted but soared in the 1980s and 1990s, in spite of significant changes in important currencies such as the yen, the mark and the dollar. This paper reports that manufacturing importers tend to suffer trade deficits whereas exporters of manufacturing products tend to enjoy trade surpluses. The reason lies in the higher rates of productivity growth experienced by exporters of manufactures.     

Survey evidence on forecast accuracy of U.S. term spreads

Successful portfolio management strategies partly require accurate forecasts of term spreads. Such forecasts may also be useful for policymaking since the yield curve may contain predictive information for economic growth. This study asks whether experts accurately predict term spreads. We show that the consensus forecasts from two separate panels, while superior to alternative benchmark forecasts, are free of systematic bias but unable to replicate the degree of variability in the actual change. Moreover, these forecasts are directionally accurate under symmetric loss, implying that they are of value to a market participant who assigns similar costs to incorrect upward and downward moves.     

Risk mitigation of post-earthquake fire in urban buildings

Post-earthquake fire (PEF) is considered one of the most high risk and complicated problems affecting buildings in urban areas and can cause even more damage than the earthquake itself. However, most standards and codes ignore the implications of PEF and so buildings are not normally designed with PEF in mind. What is needed is for PEF factors to be routinely scrutinized and codified as part of the design process. A systematic application is presented as a means of mitigating the risk of PEF in urban buildings. This covers both existing buildings, in terms of retrofit solutions, and those yet to be designed, where a PEF factor is proposed. To ensure the mitigation strategy meets the defined criteria, a minimum time is defined – the safety guaranteed time target – where the safety of the inhabitants in a building is guaranteed.     

The behaviour of the US consumer price index 1913–2003: a study of seasonality in the monthly US CPI

This article analyses the seasonality in the monthly consumer price index (CPI) over the period January 1913 to December 2003. We examine three types of month effects: if the mean of monthly CPI changes of the entire data set, and of a given month were significantly different from zero; if the mean of monthly CPI changes of a given month was different from the mean of the other months; and if the variance of the monthly CPI changes for a given month was different from the variance of the other months. The mean of monthly CPI changes for the entire data set (0.27%) was found to be significantly greater than zero. The means of monthly changes show a downward trend from September to December. When the data are sliced into three sub-periods, we find an increasing trend in the means and medians of monthly changes but a decreasing trend in the SDs of the monthly changes. The mean of monthly CPI changes during the republican presidencies (0.15%) was significantly lower than during the democratic presidencies (0.38%).     

Are professional forecasts of growth in US business investment rational?

Utilizing comparable time-series forecasts as benchmarks, we document the “weak” and “stronger” rationality of professional forecasts of growth in business investment for 1982-2009. Consistent with these findings, the forecasts are directionally accurate and imply symmetric loss.
