HOUSING DYNAMICS OVER THE BUSINESS CYCLE

Housing construction, measured by housing starts, leads GDP in a number of countries. Measured as residential investment, the lead is observed only in the United States and Canada; elsewhere, residential investment is coincident. Variants of existing theory, however, predict housing construction lagging GDP. In all countries in the sample, nominal interest rates are low ahead of GDP peaks. Introducing long‐term nominal mortgages, and an estimated process for nominal interest rates, into a standard model aligns the theory with observations on starts, as mortgages transmit nominal rates into real housing costs. Longer time to build makes residential investment cyclically coincident.     

Aid,Environment and Climate Change

Aid and aid institutions constitute an important element of the global response to interlinked global developmental and environmental challenges. As such, these institutions are now being drawn into new arenas beyond the traditional focus on improving the livelihoods of poor people in low‐income countries. Development aid, by itself, cannot “save the planet.” Nevertheless, development aid and development institutions do have the potential to become important catalytic actors in achieving developmental and global environmental objectives. This requires bold reforms and political action. Without appropriate restructuring of the international institutional architecture to confront the new development context combined with the necessary complementary policy frameworks, future aid, including aid for environmental objectives, risks substantially under‐performing.     

How is service procurement different from goods procurement? Exploring ex ante costs and ex post problems in IT procurement

Several studies suggest that, in practice, service procurement is more challenging than goods procurement. The underlying but largely implicit argument is that the procurement process for services involves higher buyer uncertainty and therefore requires extra efforts to mitigate this uncertainty. Drawing on Transaction Cost Economics, we use a database of information technology transactions to investigate the relationship between transaction characteristics and social embeddedness, and ex ante cost and ex post problems. We explore whether the same relationships hold across transactions that involve only goods versus transactions that also involve services. Our findings support conventional wisdom that managing the procurement process for transactions involving services is more challenging than for transactions involving goods. However, when controlling for typical transaction characteristics, there is no difference between transactions involving goods and transactions that also involve services.     

Salesforce entertainment activities

Sales managers need guidelines for controlling the entertainment costs incurred by their sales personnel. Because of the difficulty in measuring the payoff associated with particular entertainment costs, the decision of whether to spend or not to spend is, of necessity, somewhat subjective. One guide is to compare entertainment activities among different salesforces. A survey of over 1300 salespeople employed in a wide variety of jobs in a large number of industries revealed the extent of entertainment efforts in five areas: taking clients out for lunch, for an evening meal, for a drink, for leisure activities, and parties for clients.     

Efficiency analysis of Norwegian district courts

This paper examines the efficiency of the Norwegian district courts with the aim of suggesting ways of improving this efficiency. Pooling the observations for the period 1983 to 1988 efficiency measures are calculated for each court using the nonparametric data envelopment analysis (DEA) method. The results show estimates of overmanning due to technical inefficiency. Comparisons are made between the specialized city courts and the generalized rural courts. When using the yearly observations Malmquist indices are calculated to estimate the rate of productivity change. Finally the paper addresses the questions of how the information from DEA can be used by the courts to become more efficient.The editor of this paper was Knox Lovell.     

Reaping the Fruits of Science: Comparing Exploitations of a Scientific Breakthrough in European Innovation Systems

This paper is an attempt to unpack the emergence and dynamics of science-based technologies in conceptual forms that allow us to understand better when and how the social and economic organization of search and problem-solving matters. The evolution over two decades of a specific science-based technology is mapped with data from its 192 patents. For the five European countries generating the majority of patents, we identify the host organizations of all 275 inventors involved in the R&D behind the patents. Using network analysis we then map the evolution of separate innovation systems and their structural and evolutionary characteristics. The best performing system combines a cumulative pattern with frequent and shifting connections to non-system R&D partners while maintaining a small core of almost omnipresent inventor-organizations. The role of multinational corporations in orchestrating innovation systems is apparent.

How Cloudy a Crystal Ball: A Psychometric Assessment of Concept Testing*

Although traditional and conjoint forms of concept testing play an important role in the new product development process, they largely ignore data quality issues, as evidenced by the traditional reliance on the percent Top‐2‐Box scores heuristic. The purpose of this research is to reconsider the design of concept testing from a measurement theory (generalizability theory) perspective and to use it to suggest some ways to improve the psychometric quality of concept testing. Generalizability theory is employed because it can account for the multiple facets of variation in concept testing, and it enables a concept test to be designed to provide a required level of accuracy for decision making in the most effective way, whether the purpose of measurement is to scale concepts or something else, such as to scale respondents. The paper identifies four types of sources—concept‐related factors, response task factors, situational factors, and respondent factors—that can contribute to the observed variation in concept testing and develops six research propositions that summarize what is known or assumed about their contribution to observed score variance. Four secondary data sets from different concept testing contexts are then used to test the propositions. The results provide new insights into the design of concept tests and the psychometric quality of the concept testing data: (1) the concepts facet is not a major contributor to response variation; (2) of the response task factors, concept formulations are a trivial source of variance, but items are not always a trivial source of variance; (3) the situational factors that are investigated are trivial sources of variance; (4) respondents are always a major contributor to the total variation; (5) concepts by respondents are not always a major contributor and the other interactions are often not trivial; and (6) residual error is always a major source of variance. Additionally, the analyses of the secondary data sets enable some useful managerial conclusions to be drawn about the design of concept testing. First, the sample size needed to reliably scale concepts depends on the types of concepts being tested. Second, averaging over items provides considerably more reliable information than relying on a single item. Third, which specific item performs best is inconsistent and very context specific. The popular purchase intention item is never the best single item to use. Fourth, not much is gained by sampling levels of the response task factors. Finally, concept testing should be designed to meet the needs of specific managerial tasks.     

Research Strategies in Science-based Start-ups: Effects on Performance in Danish and Swedish Biotechnology

Although biotech start-ups fail or succeed based on their research, few attempts have been made to examine if and how they strategise in this core activity. Using a unique comprehensive dataset on Danish and Swedish biotech start-ups in drug discovery this paper adopts a Simonean approach to analysing the research strategies of small dedicated biotech firms (DBFs), focusing on three interrelated issues: (i) characterising the problem architectures addressed by different types of DBFs; (ii) testing and confirming that DBFs form requisite research strategies, by which we refer to problem-solving approaches developed as congruent responses to problem architectures; and (iii) testing and confirming that financial valuation of firms is driven by achievements conforming to requisite research strategies. These strategies, in turn, require a careful combination of multiple dimensions of research. The findings demonstrate that Schoonhoven's argument that 'strategy matters' is valid not only for the larger high-tech firms covered by her study, but also for small research-based start-ups operating at the very well-springs of knowledge where science directly interacts with technologies. Although more research is needed along these lines, these findings offer new implications for the understanding, management and financing of these firms.
