A productivity study of the Norwegian building industry

Slow productivity growth in the building and construction industry is often put forward as the cause of rising building costs. In view of the importance of the building sector in the national economy, factual empirical knowledge is hard to come by. The few studies found are usually carried out on a sectoral level and based on time-series data. However, to come to grips with the real causes for slow productivity growth, one has to analyze at the microlevel of actual decision making. Our study is based on establishment data for 1986. The method of analysis is the deterministic frontier approach. The efficiency distributions show large variations with average structural efficiency about 20 percent. Thus, there is significant scope for productivity improvement if average performance can catch up with best practice.The refereeing process of this article was handled through T.G. Cowing.     

Supplier Development Responsibility and NPD Project Outcomes: The Roles of Monetary Quantification of Differences and Supporting‐Detail Gathering

Firms increasingly rely on suppliers to perform tasks in new product development (NPD). Research has only recently begun to focus on the processes to manage this supplier development responsibility, and has hardly investigated how firms collect and analyze information regarding the cost and performance of alternative supplier offerings. Our study addresses this gap, through a field survey among 144 paired samples of project leaders and cost analysts involved in the same NPD projects. On the basis of literature and qualitative research, we conceptualize a substantive model. We first use a substantive validity assessment to vet the measures for the proposed constructs. We then test the substantive model with structural equation modeling using a multiple‐sample analysis. The results strongly show that monetary quantification of differences and detail gathering play significant roles in successfully leveraging supplier development responsibility. The findings support the hypothesis that the extent of development responsibility that suppliers have leads the development team to a more focused monetary quantification of the differences in alternative supplier offerings. Monetary quantification of differences has a significant, positive effect on the extent of supporting‐detail gathering and on the development speed of the project, whereas supporting‐detail gathering has a significant, positive effect on the product advantage of the new product as well as development speed. These findings are robust across the two functional perspectives. Our study complements the literature on interfirm control and monitoring by demonstrating the effects of selective and focused output controls.     

Does Increased Extraction of Natural Gas Reduce Carbon Emissions?

Without an international climate agreement, extraction of more natural gas could reduce emissions of CO₂ as more clean natural gas may drive out dirty coal and oil. Using a computable equilibrium model for the Western European electricity and natural gas markets, we examine whether increased extraction of natural gas in Norway reduces global emissions of CO₂. We find that both in the short run and in the long run total emissions are reduced if the additional quantity of natural gas is used in gas power production in Norway. If instead the additional quantity is exported directly, total emissions increase both in the short run and in the long run. However, if modest CO₂-taxes are imposed, increased extraction of natural gas will reduce CO₂ emissions also when the additional natural gas is exported directed.earlier version of this paper was presented at the 25th Annual IAEE International Conference in Aberdeen June 2002.     

Takeover activity in Australia: endogenous and exogenous influences

The present paper analyses the population of takeover bids for listed Australian companies using quarterly data over a 25-year period to re-examine the predictability of takeover activity and to determine if there is a flow on impact on macroeconomic variables. We examine whether takeover activity: (i) is endogenous; that is, determined by own activity; (ii) is jointly determined by macroeconomic and capital market variables; and (iii) has an exogenous spillover impact across the economy. We find that stock prices and takeover activity share a long-term common trend, the relative success of takeover bids is independent of sharemarket activity, and conclude that aggregate takeover activity is driven by fundamental economic factors rather than by speculative activity.     

Managing Supplier Involvement in New Product Development: A Multiple‐Case Study*

Existing studies of supplier involvement in new product development have mainly focused on project‐related short‐term processes and success factors. This study validates and extends an existing exploratory framework, which comprises both long‐term strategic processes and short‐term operational processes that are related to supplier involvement. The empirical validation is based on a multiple‐case study of supplier collaborations at a manufacturer in the copier and printer industry. The analysis of eight cases of supplier involvement reveals that the results of supplier–manufacturer collaborations and the associated issues and problems can best be explained by the patterns in the extent to which the manufacturer manages supplier involvement in the short term and the long term. The results of this study reveal that the initial framework is helpful in understanding why certain collaborations are not effectively managed yet conclude that the existing analytical distinction among four different management areas does not sufficiently reflect empirical reality. This leads to the reconceptualization and further detailing of the framework. Instead of four managerial areas, this study proposes to distinguish between the strategic management arena and the operational management arena. The strategic management arena contains processes that together provide long‐term, strategic direction and operational support for project teams adopting supplier involvement. These processes also contribute to building up a supplier base that can meet current and future technology and capability needs. The operational management arena contains processes that are aimed at planning, managing, and evaluating the actual collaborations in a specific development project. The results of this study suggest that success of involving suppliers in product development is reflected by the firm's ability to capture both short‐ and long‐term benefits. If companies spend most of their time on operational management in development projects, they will fail to use the leverage effect of planning and preparing such involvement through strategic management activities. Also, they will not be sufficiently able to capture possible long‐term technology and learning benefits that may spin off from individual projects. Long‐term collaboration benefits can only be captured if a company can build long‐term relationships with key suppliers, with which it builds learning routines and ensures that the capability sets of both parties are aligned and remain useful for future joint projects.     

Multi-equation modelling of desirable and undesirable outputs satisfying the materials balance

The key feature when modelling joint production of intended outputs and unintended residuals is that the latter stem from the use of material inputs. A multi-equation model building on the factorially determined multi-output model of classical production theory satisfies the materials balance that tells us that the mass contained in inputs cannot disappear, but must turn up in the desirable outputs or end up as residuals. In this model, potentially complex technical relationships are simplified to express each of the intended outputs and the residuals as functions of the same set of inputs. Serious problems with the single-equation models most often found in the literature are demonstrated. Abatement activity in the form of end of pipe is added, and an optimal planning solution is derived using the concept of an environmental damage function for the impact of discharge of residuals into the natural environment. It is shown that the traditional environmental policy instruments, like direct regulation restricting the amount of undesirable residuals discharged to the environment, a Pigou tax on pollutants, and cap and trade, all function well. Extending the multi-equation model to allow for inefficiency, three efficiency measures are introduced: desirable output efficiency, residuals efficiency, and abatement efficiency. It is conjectured that these measures can be estimated independently using the DEA model.     

Globally correlated nominal fluctuations

Fluctuations in nominal variables—aggregate price levels and nominal interest rates—are documented to be substantially more synchronized across countries at business cycle frequencies than fluctuations in real output. A transparent mechanism accounting for this striking feature of the nominal environment is described and quantitatively evaluated. It is based on the interaction between (small) cross-country spillovers of shocks, Taylor rules, and domestic no-arbitrage conditions. The mechanism is robust to various parameterizations and extensions aligning the model with other important aspects of domestic and international fluctuations. Furthermore, its key features are consistent with cross-country forecasts from Consensus survey.
