On the measurement of dynamic effects of integration

By allowing a freer interplay of market forces, the market liberalization involved in closer economic integration can improve the efficiency of productive factors. This permits greater output from the same inputs. A side effect of this improved efficiency is an improved investment climate in the integrating region. This in turn will result in a higher investment rate, thereby augmenting the initial output gains by providing the economy with more resources. The same sort of induced capital formation can also boost investment in human capital and knowledge capital. Primitive calculations of the size and timing of these induced capital formation can be made using an aggregate GDP function. A rough approximation of the adjustment path shows that the extra investment will stimulate growth for decades, although half of the total effect will occur in the first 10 to 50 years.     

Learning Why More Learning Takes Place in Some Classrooms Than Others

Abstract. The relatively poor average performance of German students on the recent PISA international evaluations of 15- and 16-year-olds' literary skills (2000) and mathematical skills (2003) and the wide variation in performance, with low-income students scoring particularly poorly, have led to calls for reforms of the German educational system. Understanding why students in some classrooms learn more than do those in other classrooms is an important first step in considering alternative reform strategies. Possible explanations include differences in teacher quality, class sizes and peer groups, and also differences among the types of secondary schools that parents select for their children. This paper illustrates a set of techniques that are useful in examining the roles these factors play in predicting why, net of family background and prior achievement, the average achievement of children in some classrooms is much higher than that of children in other classrooms. We illustrate the use of these techniques with a dataset from Bogotá, Colombia, that has two attractive properties. First, some teachers teach multiple classes of students. Second, students are enrolled in schools in two sectors (public and private). Application of the techniques described in this paper could shed light on the reasons why the average academic achievement of German students attending some schools is much higher than that of German students attending other schools.     

Innovation and knowledge-intensive business service: the contribution of knowledge-intensive business service to innovation in manufacturing establishments

It is well established that knowledge-intensive business service (KIBS) firms can be innovators in their own right. It is also well established that KIBS can contribute to innovation in their client firms. This role of KIBS has been theorised, and some of the processes by which KIBS contribute to innovation have been scrutinised by way of case studies. However, there are few, if any, large-scale analyses that permit the two following questions to be addressed: (i) Do firms that use KIBS systematically introduce more innovations than those that do not? (ii) Is recourse to certain types of KIBS associated with certain types of innovation? Our survey of KIBS use across 804 manufacturing establishments in Quebec shows that KIBS contribute to their client's innovation – thereby confirming in a more general way what has been observed in case studies – but also that different types of KIBS contribute to different types of innovation.     

Ownership structure and hospital service costs and fees: A decomposition approach

This paper analyzes hospital characteristics that are associated with higher average costs and charges for venipuncture, computed tomography procedures (computerized axial tomography [CAT] scans), and electrocardiograms (EKG). Using data from a Medicare database, our results indicate that higher wages, larger hospital sizes, and greater service quality are associated with higher procedure costs, whereas system membership is generally associated with lower procedure costs. Blinder‐type decompositions, which are the main focus of this study, suggest (a) that venipuncture costs are about 17% to 19% lower at proprietary hospitals than at nonprofit or government hospitals, (b) CAT scan costs are about 6% to 12% lower at nonprofit hospitals than at proprietary and government hospitals, and (c) that EKG costs are about 3% lower at proprietary hospitals than at nonprofit or government hospitals. Lastly, large portions of each of these differences are found to be due to both differences in mean values of the hospitals' characteristics by ownership type and differences in the mechanism by which the hospitals' characteristics are transmitted to procedure costs.     

The moderating influence of strategic orientation on the strategy formation capability–performance relationship

An effective strategy formation capability is a complex organizational resource—a dynamic capability that should lead to superior performance. Strategy scholars have examined the strategy formation capability from many perspectives. However, no study has examined a comprehensive model of strategy formation in the context of the firm's strategic orientation. We develop and examine such a model. The results show that strategic orientation moderates the relationship between different elements of the strategy formation capability and performance. Copyright © 2006 John Wiley & Sons, Ltd.     

Discretionary and Non-Discretionary Revisions of Loss Reserves by Property-Casualty Insurers: Differential Implications for Future Profitability, Risk and Market Value

We develop and estimate a PC-industry specific model in which proxies for both discretion and non-discretion are used to partition loss reserve revisions into discretionary and non-discretionary components. The use of such proxies enables us to test directional hypotheses about the relations between the revision components and future profitability, risk and market value. We predict and find that discretionary revisions are negatively associated with future profitability, positively associated with firm risk, and negatively associated with market-to-book ratios. We predict and find that non-discretionary revisions are positively associated with future profitability and risk but are not associated with market-to-book ratios.     

The informational relevance of corporate social responsibility: evidence from DS400 index reconstitutions

This study examines the relationship between corporate social responsibility and financial performance by analyzing the intra‐industry wealth impact of additions and deletions to the Domini Social 400 index. Results from the event study analysis indicate that additions to the index generate a positive share price response for the announcement firm and a negative response by rival firms. The opposite reaction is observed for index deletions. Additionally, the share price response is more pronounced for informationally opaque industries. Our study highlights the importance of external monitoring agencies in providing meaningful information that helps resolve investor uncertainty regarding the quality of a firm's relationships with its primary stakeholders.
