Accounting and capital market measures of risk: Evidence from Asian banks during 1998–2003

This study examines the relation between accounting and capital market risk measures for a sample of 46 listed Asian banks during the period 1998–2003. By applying a panel data analysis that includes a control for country-specific factors, the results show that the standard deviation of the return-on-assets and loan-loss-reserves-to-gross-loans are significantly related to total risk. Also gross-loans-to-total-assets and loan-loss-reserves-to-gross-loans are significantly related to non-systematic risk. These results indicate that in these Asian countries, firm-specific risk is more important than systematic risk and the results are robust even though significant differences exist across Asian countries in banking activities, capital adequacy requirements, and deposit insurance protection.     

New Product Development Speed: Too Much of a Good Thing?

New product development (NPD) speed has become increasingly important for managing innovation in fast‐changing business environments due to continuous reduction in the product life cycle time and increase in competition from technological advancements and globalization. While the existing literature has not produced consistent results regarding the relationship between speed and success for NPD projects, many scholars and practitioners assert that increasing NPD speed is virtually always important to NPD success. The purpose of this paper is to examine the implicit assumption that faster is better as it relates to new product success (NPS). From the perspectives of time‐compression diseconomies and absorptive capacity, the authors question the assumption that speed has a linear relationship with success. The authors further argue that time‐compression diseconomies depend on levels of uncertainty involved in NPD projects. Using survey data of 471 NPD projects, the hypotheses were tested by hierarchical regression analysis and subgroup polynomial regression. The results of this study indicate that NPD speed has a curvilinear relationship with NPS, and the nature of the speed–success relationship varies, depending on type and level of uncertainty. When turbulence or technological newness is high, the relationship is curvilinear, but when uncertainties are low, the relationship is linear. In contrast, the results of this study suggest a curvilinear relationship under conditions of low market newness but not when market newness is high. The present paper asserts that time‐compression diseconomies and absorptive capacity are important theoretical constructs in understanding speed in NPD. The different impact of market newness and market turbulence on NPD speed supports the distinction of newness and turbulence as two different sources of uncertainty. Discussion focuses on the implications of NPD speed under the different conditions of uncertainty. NPD teams need to pursue NPD speed as a critical strategy, but it is necessary to analyze the source and degree of uncertainty about projects before a time‐based strategy is selected. In order to address the challenges of high uncertainty, a firm needs to probe, learn, and iterate fast. In particular, NPD teams need to distinguish between the different requirements for new products in emerging and new markets, and those in fast‐changing markets. Moreover, NPD teams need to balance how fast they need to go with how fast they can go by considering team absorptive capacity and customer absorptive capacity.     

Labour and capital saving technical change in telecommunications

The Australian telecommunications sector is being improved and extended through substantial recent investment in intelligent technology such as digital switching, fibre optics, satellite and cellular transmission, and the Internet. These technologies are being progressively integrated with technology from the broadcasting, computer and electronics industries, providing a unified information infrastructure for information transmission and processing. Technological progress embodied in new equipment has the effect of increasing the efficiency of the factors of production. Such efficiency increases can be biased towards a particular factor. For instance, the impact of labour-augmenting technical change is a decline in the cost of labour per unit of production. When such biases are apparent the relativity between the costs of labour and capital per unit of production is changed. In the longer term, technical change can impact on the rate of employment growth and also on the rate of capital accumulation. In this study the Australian telecommunications cost structure is examined for the period 1919 to 1988. To measure labour saving and capital saving technical change a translog cost model is estimated. Multiproduct telecommunications cost studies typically employ the translog cost model (Evans and Heckman, 1984; Roöller, 1990a; 1990b; Shin and Ying, 1992; McKenzie and Small, 1997). The translog model places no a priori restrictions on substitution possibilities among the factors of production, and allows scale economies to vary with the level of output.     

Experimental methods: Between-subject and within-subject design

In this article we explore the issues that surround within-subject and between-subject designs. We describe experiments in economics and in psychology that make comparisons using either of these designs (or both) that sometimes yield the same results and sometimes do not. The overall goal is to establish a framework for understanding which critical questions need to be asked about such experimental studies, what authors of such studies can do to ameliorate fears of confoundedness, and which scenarios are particularly susceptible to divergent results from the two approaches. Overall, we find that both designs have their merits, and the choice of designs should be carefully considered in the context of the question being studied and in terms of the practical implementation of the research study.     

Order with Some Law: Complementarity versus Substitution of Formal and Informal Arrangements

While some argue that incomplete incentive contracts facilitatethe self-enforcement of informal dealings, other authors submitthat they substitute for or "crowd out" social norms supportinginformal arrangements. We use experimental evidence to testthese theories by manipulating the extent to which individualstransact repeatedly and the level of contract costs. We findthat, by enforcing contractible exchange dimensions, contractsfacilitate the self-enforcement of noncontractible dimensions.This complementarity effect is particularly important when repetitionis unlikely and thus self-enforcement is difficult. Althoughour data suggest the existence of reciprocity as an alternative,informal enforcement mechanism, we do not find evidence thatcontracts substitute for this social norm.
