Barriers to the “key supplierization” of the firm

The phenomenon of key supply management (KSM) in business companies is far less investigated than the phenomenon of key account management (KAM) which beneficiates, both in practice and in an academic context, from a growing interest. This article is based on the empirical analysis of a sample of 10 international companies which have recently launched KSM programmes or are currently working on launching such programs. It examines the difficulties these companies come up against when implementing such programmes and proposes to organize these difficulties around three dimensions: 1) the difficulties in implementing real supplier portfolio approaches; 2) the narrow view of value co-creation with suppliers, and 3) the persistent lack of integration of the purchasing function with other internal functions within the company. The conclusion of the article is that KSM is far from being a mere symmetric phenomenon of KAM. Several implications are then discussed in relation to the implementation of KSM programmes within companies.     

Virtual Experiments and Their Use in Teaching Experimental Design

The ability to design experiments in an appropriate and efficient way is an important skill, but students typically have little opportunity to get that experience. Most textbooks introduce standard general‐purpose designs, and then proceed with the analysis of data already collected. In this paper we explore a tool for gaining design experience: computer‐based virtual experiments. These are software environments which mimic a real situation of interest and invite the user to collect data to answer a research question. Two prototype environments are described. The first one is suitable for a course that deals with screening or response surface designs, the second one allows experimenting with block and row‐column designs. They are parts of a collection we developed called ENV2EXP, and can be freely used over the web. We also describe our experience in using them in several courses over the last few years.     

The reluctance of construction purchasers towards project partnering

While the literature argues that there are several benefits for construction purchasers who join forces to co-develop the project with contractors and to increase cooperation between the various project stakeholders (construction partnering), little research has been done on the reasons for the lack of extensive diffusion of such methods in the construction industry. This paper aims at understanding the rationale behind the reluctance of construction purchasers for this coordination mechanism in France. In particular the paper investigates the impact of the characteristics of the project but also of the characteristics of the purchasing companies in their project procurement behaviour. The findings reveal that the characteristics of the purchasing companies in terms of purchasing strategy, structure and culture seem more explanatory of their procurement behaviour than of the project characteristics. The paper suggests that the lack of diffusion and understanding of construction partnering may be due to the resistance of purchasers who feel threatened by the structural changes it involves in their purchasing habits.     

Gold rush fever in business cycles

A flexible price model of the business cycle is proposed, in which fluctuations are driven primarily by inefficient movements in investment around a stochastic trend. A boom in the model arises when investors rush to exploit new market opportunities even though the resulting investments simply crowd out the value of previous investments. A metaphor for such profit driven fluctuations are gold rushes, as they are periods of economic boom associated with expenditures aimed at securing claims near new found veins of gold. An attractive feature of the model is its capacity to provide a simple structural interpretation to the properties of a standard consumption and output Vector Autoregression.     

Tax Pot Episodes in OECD Countries

How to use an unexpected increase in tax revenues (tax pots) was an important issue in most OECD countries in the second half of the 1990s, the question being more precisely what to do with those windfall revenues: decrease taxes, reduce debt, increase expenditures? In this paper, we study such tax pot episodes in OECD countries over the past 40 years. To that end, we propose a definition of a fiscal pot episode. Once identification is complete, we examine the macroeconomic environment within in those episodes, the way this surplus of revenues has been used, and the degree of success in reducing public debt and in fostering growth. As in the fiscal adjustment literature, we then obtain relatively orthodox conclusions about the use of windfall tax revenues, as it is generally better for future growth and debt level to use the money to reduce expenditures and taxes.

An exploration into Pigou's theory of cycles

This paper explores a theory of business cycles in which recessions and booms arise due to difficulties encountered by agents in properly forecasting the economy's future needs in terms of capital. The idea has a long history in the macroeconomic literature, as reflected by the work of Pigou (Industrial Fluctuation, MacMillan, London, 1926). The contribution of this paper is twofold. First, we illustrate the type of general equilibrium structure that can give rise to such phenomena. Second, we examine the extent to which such a model can explain the observed pattern of U.S. recessions (frequency, depth) without relying on technological regress. We argue that such a model offer a framework for understanding elements of both the recent U.S. recession and of the Asia downturns of the late 1990s.     

The “news view” of economic fluctuations: Evidence from aggregate Japanese data and sectoral US data

This paper uses aggregate Japanese data and sectoral US data to explore the properties of the joint behavior of stock prices and total factor productivity (TFP) with the aim of highlighting data patterns that are useful for evaluating business cycle theories. The approach used follows that presented in [Beaudry, P., Portier, F., 2004. News, stock prices and economic fluctuations. Working paper 10548. NBER]. The main findings are that (i) in both Japan and the US, innovations in stock prices that are contemporaneously orthogonal to TFP precede most of the long-run movements in total factor productivity and (ii) such stock prices innovations do not affect US sectoral TFPs contemporaneously, but do precede TFP increases in those sectors that are driving US TFP growth, namely durable goods, and among them equipment sectors.
