Purchasing professional services: A transaction cost view of the antecedents and consequences of purchasing formalization

Professional services represent an increasing share of expenditures in contemporary organizations. While these services are often of strategic importance, they are also perceived as being difficult to purchase and use, which creates challenges for the purchasing process. In order to address these challenges, organizations are increasingly engaging in systematic efforts to improve their ability to purchase professional services. These efforts focus on formalizing the purchasing process by introducing policies, guidelines, and other measures for the hiring of service suppliers. Based on a transaction cost economic framework, the current paper investigates the nature, antecedents and consequences of formalization initiatives in the purchasing of professional services. The results from a cross-sectional study of 76 large Swedish organizations show that the formalization of purchasing professional services takes two different forms: the formulation of policies and the establishment of preferred supplier agreements. The former is driven by company size, whereas the latter is driven by the frequency of purchase transactions. Only the establishment of policies, however, is found to be positively related to organizations' perceived ability to purchase professional services.     

Costco and the Aussie Shopper: a case study of the market entry of an international retailer

Retailing is a globalised industry, yet retailers must respond to local shopping habits if they are to be perceived as legitimate by the host country customers. However, some retailers may be unable or unwilling to respond to all customer requirements. Costco, the membership warehouse club retailer, has been successful in its international expansion efforts, establishing its first Australian store in Melbourne in 2009. In the first 12 months of operation, the store became one of Costco's top five stores in the world. We investigated this success by focussing on the customer and used institutional theory to analyse what concessions were made by the customer and the company. Data were collected from consumer interviews, site visits and secondary media and industry sources. Analysis revealed negotiations based on the rejection, acceptance or adaptation of the regulative, normative and cultural cognitive aspects of the Australian shopper and the Costco business model. Customers made concessions to accommodate the new business model, and Costco responded to entrenched Australian shopping habits. This case is the first to explore the outcome of retail internationalisation from the customers' perspective, revealing the concept of mutual concessions. The interaction and subsequent adaptation by both customer and retailer have resulted in the institutionalisation of new shopping norms in the host country and success for the international retailer.     

A Monte Carlo approach to compute the asymptotic standard errors of dynamic multipliers

A Monte Carlo method to compute asymptotic standard errors of dynamic multipliers is proposed. It is applied to Hein's Model I to find standard error of interim multipliers of taxes on nominal income.     

The great moderation of the term structure of UK interest rates

The conduct of monetary policy, the term structure of interest rates and the structure of the economy in the UK have changed over the post-WWII period. We model the interaction between the macroeconomy and financial markets using a time-varying VAR augmented with the factors from the yield curve. There is evidence of a great moderation in the dynamics of the yield curve, with the factors being persistent and volatile before the introduction of inflation targeting in 1992 but becoming stable afterwards. The introduction of time-variation in the Factor Augmented VAR improves the fit of the model and results in expectation hypothesis consistent yields that are close to actual yields, even at long maturities. Monetary policy shocks had a significant impact on the volatility of inflation, output and the policy rate over the pre-inflation targeting era, but their contribution has been negligible under the current regime. Shocks to the level of the yield curve accounted for a large fraction of inflation variability only before 1992.     

Enabling open innovation in small‐ and medium‐sized enterprises: how to find alternative applications for your technologies

A critical success factor in the practice of Open Innovation is the timely identification of opportunities for out‐licensing a firm's technologies outside its core business. This can be particularly challenging for small‐ and medium‐sized enterprise (SMEs), because of their focussed business portfolio, specialized knowledge basis, and limited financial resources that can be devoted to innovation activities. The paper illustrates a quick and easy‐to‐use methodology for the identification of viable opportunities for out‐licensing a firm's technologies outside its core business. The method uses established TRIZ instruments in combination with non‐financial weighting and ranking techniques and portfolio management tools. It has been developed by the authors in collaboration with an Italian SME working in the packaging industry.     

Improving forecasting for telemarketing centers by ARIMA modeling with intervention

In this study we analyze existing and improved methods for forecasting incoming calls to telemarketing centers for the purposes of planning and budgeting. We analyze the use of additive and multiplicative versions of Holt–Winters (HW) exponentially weighted moving average models and compare it to Box–Jenkins (ARIMA) modeling with intervention analysis. We determine the forecasting accuracy of HW and ARIMA models for samples of telemarketing data. Although there is much evidence in recent literature that “simple models” such as Holt–Winters perform as well as or better than more complex models, we find that ARIMA models with intervention analysis perform better for the time series studied.     

Unemployment persistence: does the size of the shock matter?

One of the stylized facts of unemployment is that shifts in its mean rate between decades and half-decades account for most of its variance. In this paper, we use a statistical analysis based on Markov switching regression models to identify the dates of infrequent changes in the mean of the unemployment rate series of fifteen countries. We find that in most countries, unemployment persistence is much reduced once the (infrequently) changing mean rate, induced by large shocks to unemployment, has been removed. We conclude that the observed persistence in unemployment appears to be consistent with multiple equilibria models and models with an endogeneous natural rate. © 1998 John Wiley & Sons, Ltd.
