On the Behaviour of Phillips–Perron Tests in the Presence of Persistent Cycles

In this paper, we analyse the impact of persistent cycles on the well‐known semi‐parametric unit root tests of Phillips and Perron (1988, Biometrika, Vol. 75, pp. 335–346). It is shown, both analytically and through Monte Carlo simulations, that the presence of complex (near) unit roots can severely bias the size properties of these tests. Given the popularity of these tests with applied researchers and their routine presence in most econometric software packages, the results presented in this paper suggest that practitioners should treat the outcomes of these tests with some caution when applied to data which display a strong cyclical component.     

Property development firms IPOs in Brazil： Was there overpricing or not？

Between September 2005 and October 2007, representative companies of the Brazilian residential real estate market adopted a strategy intended to increase their investment capacity by Initial Public Offer （IPO）. The setting at that time was favorable for constructing residential real estate designed for the middle class, in view of two main factors： First, in 2005, a restructuring of the Brazilian finance system had relaxed requirements needed to receive financing for the purchase of residential property; Second, there was substantial demand in the middle class market because most developers had been focusing on the upper class market in order to guarantee the sale resources in the production phase. Thus, it was necessary to enhance the investment capacity of the real estate companies to attend the middle-class demand. These two factors, associated with a favorable outlook for the Brazilian, as well as the global economy, encouraged those representative companies to rapidly increase their investment capacity by IPO in a short time. The focus of this article is to analyze the quality of the investments in the stock of these real estate companies （21 offers were taken into account in the analysis）. In order to identify what these companies＇ expectations were and how they supported their decisions to enter BOVESPA with their designated prices and amounts, correlating offers against the BOVESPA Index （market index） were also analyzed. The results allow concluding that these offers were not supported by validated procedures of pricing, but rather were just speculative offers, even though we do take into account the investment grade granted to the Brazilian economy within the period concerned in our analysis.     

Teachers as servants of state ideology: Sousa and Sales,Portuguese School of Commerce, 1759–1784

This paper draws upon Althusser [Althusser L, Ideology and ideological state apparatuses (notes towards an investigation). In: Althusser L, editor. Lenin and philosophy and other essays [Brewster B, Trans.]. London: New Left Books; 1971] to conceive two teachers of commercial subjects as apparatchiks serving an ideological state apparatus in order to diffuse a state ideology. We explore the lives of João Henrique de Sousa and Albert Jaquéri de Sales, the first two teachers of the Portuguese School of Commerce, established in Lisbon in 1759. Sousa and Sales were important propagators of commercial knowledge and mercantilist State ideology during the regime of the Marquis of Pombal (Chief Minister of Portugal, 1756–1777). We explore their role as operatives of an “ideological state apparatus” and the contribution they made to the growth of indigenous commercial know-how and the development of the Portuguese economy. We explore how their status in Portuguese society was related to the fortunes of the regime they served.     

THE IMPACT OF DEMAND UNCERTAINTY AND CONFIGURATION CAPACITY ON CUSTOMER SERVICE PERFORMANCE IN A CONFIGURE‐TO‐ORDER ENVIRONMENT

This paper examines the simultaneous impact of demand variability, demand skew, and configuration capacity on customer service in a configure‐to‐order environment. Simulation is done in ARENA and data are analyzed using ANOVA and MANOVA. The findings indicate that the factors studied have differential impact on performance both individually and interactively.     

The Performance of Agricultural Market Advisory Services in Corn and Soybeans

The purpose of this article is to evaluate the performance of market advisory services for the 1995–2003 corn and soybean crops. A new database from the Agricultural Market Advisory Services (AgMAS) Project is used in the evaluation. This database should not be subject to survivorship and hindsight biases. Overall, the results provide little evidence that advisory services as a group outperform market benchmarks, particularly after considering risk. The evidence is more positive versus the farmer benchmarks, even after taking risk into account. Results also suggest that it is difficult to predict the pricing performance of advisory services across crop-years.     

The Dynamics of Influence in Corporate Co‐Evolution

This paper aims to offer new theoretical and empirical insights into co‐evolutionary development. Theoretically, it advances a political perspective which focuses on the role of power and how this can be translated into influence as an evolutionary driver through the relational framework between an organization and external parties. Empirically, the paper elaborates this perspective by reference to how China's largest container terminal evolved within a changing environment, and how its evolution in turn impacted on the evolution of its sector. In this case, the key relational framework was that between the organization and government institutions. Application of a political perspective to the case study suggests a theoretical model that can inform future research and practice.     

Relationship portfolios and capability development: Cases from the moulds industry

A number of authors within business marketing and purchasing, have stressed that the heterogeneity of relationships in customer and supplier portfolios are a source of managerial problems and opportunities. This paper looks at the use and development of firms’ capabilities in the context of relationship portfolios. Two case studies about producers of moulds are used to illustrate how their contrasting trajectories in terms of degree of specialisation can be related to the variety found and sought in their portfolios of relationships. Our study suggests that portfolio interdependencies are best understood in the context of the development of idiosyncratic capabilities, which include interpretations and experiences in using and influencing that variety.
