Linking learning and effective process implementation to mass customization capability

This study investigates the role of learning and effective process implementation in the development of mass customization capability. Building upon the knowledge-based view of the firm, we argue that internal and external learning are two knowledge-generation routines that contribute to effective process implementation. Effective process implementation, in turn, is a knowledge-based manufacturing capability, which, as a function of internal and external learning, leads to mass customization capability. We employ structural equation modeling to empirically test the effects of learning on mass customization capability, mediated by effective process implementation, using survey data collected from 100 manufacturing plants in 3 industries and 6 countries. Our results provide empirical evidence supporting the proposed model of the effect of internal and external learning on mass customization capability, fully mediated by effective process implementation. This research is one of the first studies to integrate insights from the knowledge-based view of the firm and mass customization. It complements the OM view of mass customization, which to date has largely focused on the technical side, by demonstrating the role of managerial practices and learning in cultivating mass customization capability in a manufacturing environment.     

Trend/cycle decomposition of regime-switching processes

We present a new approach to trend/cycle decomposition of time series that follow regime-switching processes. The proposed approach, which we label the “regime-dependent steady-state” (RDSS) decomposition, is motivated as the appropriate generalization of the Beveridge and Nelson decomposition [Beveridge, S., Nelson, C.R., 1981. A new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle. Journal of Monetary Economics 7, 151–174] to the setting where the reduced-form dynamics of a given series can be captured by a regime-switching forecasting model. For processes in which the underlying trend component follows a random walk with possibly regime-switching drift, the RDSS decomposition is optimal in a minimum mean-squared-error sense and is more broadly applicable than directly employing an Unobserved Components model.     

Case management: an evaluation at Childrens Hospital Los Angeles

This prospective, quantitative, and qualitative evaluation of the case management program at CHLA clearly demonstrated the value of professional service coordination of care for children with complex, special health needs. Most specifically, the program documented improvement in three discrete areas of evaluation: 1. Financial, with decreased unnecessary expenditures and increased revenue. 2. Patient satisfaction, documented with validated questionnaires. 3. Clinical process improvement, using quantifiable clinical outcomes. At the very least, case management is an extremely valuable service in the present managed health care environment, and may in fact be indispensable.     

Bank Mergers and Small Firm Finance: Evidence from Lender Liability

As a merger approaches, the value of repeat business for the target bank can drop sharply, so loan relationships between this bank and small businesses are often disrupted. Small firms sometimes experience serious value destruction as a consequence of this sudden lack of credit. This paper shows that lender liability may result from bank mergers and bankers involved in mergers often engage in aggressive, scorched‐earth defense tactics to discourage further litigation. I summarize six lender liability cases to illustrate these points. Bank mergers have been shown to reduce credit availability in a number of studies. Since small firms depend on credit for their daily existence, owners of small firms do have a reason to fear a merger of their bank with a larger institution. Analyzing merger effects with survey data of firms obtained after a bank merger, an empirical strategy used in a number of studies, raises problems since the only firms considered are the ones that survived the bank merger. Suggesting that the problem will cure itself in the long run, an argument advanced in other studies, ignores small firms' daily dependence on credit. In the long run we are all dead. Bank examiners need to evaluate an institution's litigation experience and measure a bank's organizational architecture – its ethical climate. Banks which are repeatedly involved in lender liability lawsuits should be denied future mergers until there is a change in organizational architecture. To assist in evaluating organizational architecture, banks should be required to report their litigation expense on their call reports. Furthermore, regulators should seriously consider the recent suggestion of Carow, Kane and Narayanan (2006) that they take steps to ensure that participants in bank mergers preserve target bank relationships. Otherwise negative effects on small business lending and economic growth will continue as bank consolidation proceeds.

Economic Analysis for the UK National Ecosystem Assessment: Synthesis and Scenario Valuation of Changes in Ecosystem Services

We combine natural science modelling and valuation techniques to present economic analyses of a variety of land use change scenarios generated for the UK National Ecosystem Assessment. Specifically, the agricultural, greenhouse gas, recreational and urban greenspace impacts of the envisioned land use changes are valued. Particular attention is given to the incorporation of spatial variation in the natural environment and to addressing issues such as biodiversity impacts where reliable values are not available. Results show that the incorporation of ecosystem services and their values within analyses can substantially change decisions.     

Time varying stock return predictability: Evidence from US sectors

This paper argues that dividend yield stock return predictability is time-varying. We conjecture that such time-variation is linked to the business cycle. Employing monthly data for US sector portfolios we estimate 5-year rolling fixed window predictive regressions. The resulting series of time-varying predictive coefficients is regressed on industrial production growth and a recession dummy. Our results support the view of a negative relationship between predictability and output growth. That is the strength of the predictive relationship between returns and the dividend yield is stronger during contractionary periods, while during expansions the magnitude of the relationship declines.     

The position of women and demographic policy

This article analyzes the effect of women's social roles on fertility and the possibilities of influencing fertility by means of demographic policies in the USSR. The most important influences on the birth rate are related to the changing social position of women and the functions of the family which have resulted from social, economic, and cultural transformations in the Soviet state since the revolution. The processes of industrialization, urbanization, higher labor productivity, and rising educational and cultural standards have removed the productive functions of the family and have also altered its consumer functions. The upbringing of children is increasingly labor intensive because of the need for more educated, higher quality workers. In 1970, 82% of women of working age were employed; their greater involvement in social production and reduced free time, combined with the prestige and economic and social independence gained from outside work, have encouraged a small family orientation. Comprehensive demographic policies including measures to help women combine work in social production with motherhood are needed to promote 2 or 3 child families. Along with measures aimed at the population as a whole, specific measures are needed that take into account the distinctive life styles and behavior of separate local population groups. A socialist society with a planned economy can utilize diverse methods of encouraging childbirth, including material assistance to families with children and sociopsychological measures to promote larger families.     

Buyer–Supplier and Supplier–Supplier Alliances: Do They Reinforce or Undermine One Another?

abstract    Previous research has portrayed buyer–supplier and supplier–supplier alliances as important mechanisms to foster learning and exchange efficiencies. Controversy remains, however, as to how these alliances interact. While some propose they reinforce one another (e.g. learning in horizontal ties generates positive spillovers to vertical ties), others propose a negative interplay (e.g. when increasing vertical-tie intensity, suppliers may weaken horizontal ties to avoid retaliation from buyers who wish to preserve bargaining power). We empirically test these competing views using survey data from the Brazilian auto-parts industry. In an attempt at reconciliation, we propose that the positive or negative interaction between vertical and horizontal alliances depends on the level of technological uncertainty of goods exchanged. Vertical ties seem to inhibit horizontal ties when technological uncertainty is low; when technological uncertainty is higher, vertical and horizontal ties do not seem to have any meaningful form of interaction. We discuss implications for theory and practice.
