On the construction of <Emphasis Type="Italic">E</Emphasis>(<Emphasis Type="Italic">s</Emphasis><Superscript>2</Superscript>)-optimal supersaturated designs

Supersaturated designs are an important class of factorial designs in which the number of factors is larger than the number of runs. These designs supply an economical method to perform and analyze industrial experiments. In this paper, we consider generalized Legendre pairs and their corresponding matrices to construct E(s ²)-optimal two-level supersaturated designs suitable for screening experiments. Also, we provide some general theorems which supply several infinite families of E(s ²)-optimal two-level supersaturated designs of various sizes.      

Assessing output and productivity growth in the banking industry

This paper assesses the evolution of output and productivity in the Greek banking industry for the period 1990–2006. Three main categories of bank output were estimated based on modern theoretical approaches, while for the estimation of output and productivity (partial and total factor) we relied on the index number method (Tornqvist index). We also considered the effect of labor quality on banks’ productivity and the contribution of total factor productivity to bank output growth. Bank output and labor productivity outpaced considerably the respective GDP growth and labor productivity of the Greek economy during the period under examination. Capital and total factor productivity have also improved remarkably mainly since 1999, due to the structural changes that took place within the industry, capital (mainly IT) investments and improvement in the quality of human capital.     

The Role of Location as a Selection Criterion in FDI: The Case of SMEs in Greece

The study examines the internationalization of Greek SMEs in Western Europe and the Balkan area, focusing on the role of location as a selection criterion in their FDI decisions. Data aimed at capturing SMEs’ perceptions with regard to incentives affecting their FDI based on location criteria. We find that location plays a significant role with regard to the benefits that firms gain, highlighting OLI paradigm's theoretical relevance in the examination of FDI, while presenting internationalization trends in the global environment. Findings further contribute to the adaption of effective practices to enhance firms’ competitiveness through more rational and targeted investment decisions.     

Prestigious stock exchanges: A network analysis of international financial centers

In this paper, we use methods from social network analysis to assess the relative importance of financial centers around the world. Using data from virtually the entire universe of global equity activity, we present complete rankings for 45 separate locations for the period 1990–2006. Our analysis constructs a network measure of prestige based on their ability to attract global IPOs. U.S. exchanges are effectively the unique hosts for cross-border equity activity from many other locations. Moreover, they are the destination of choice for most companies coming from locations with highly prestigious exchanges. We also document the emergence of several competing stock exchanges from developed and emerging market economies. The ascent of these stock markets, however, might reflect improved conditions in a growing global market rather than a decline in the competitiveness of U.S. exchanges.     

In pursuit of legitimacy: A history behind fair value accounting

An examination of the history of attempts by regulators, practitioners and scholars from the mid nineteenth century to 2005 to establish an appropriate accounting measurement basis for financial reporting here leads to an evaluation of the likelihood of fair value accounting (FVA) practices becoming fully institutionalised. Using concepts drawn from theories of legitimation, it is shown here that historic cost accounting (HCA) only enjoyed an episodic legitimacy in the 1940s–70s and that prior and after this period mixed measurement incorporating market values is routinised. Although principles of FVA have been legitimised to an extent, it is argued here that this has resulted in the practice of mixed measurement bases being taken for granted.     

Corporate Lobbying on Accounting Standards: Methods, Timing and Perceived Effectiveness

There is a long-standing concern in the literature about the potential importance of non-observable forms of lobbying that may be used by corporate managers to influence accounting standard setting bodies. To date, however, no study has documented their nature or their volume. This study provides such evidence in the context of the U.K.'s Accounting Standards Board (ASB) standard setting process for the period 1991–96. It also provides evidence with respect to the timing at which lobbying activity takes place and its perceived effectiveness by corporate managers. The findings suggest that companies use a variety of lobbying methods, including appeals to their auditors and private meetings with ASB members and staff. Importantly, however, the use of these methods is significantly associated with the use of comment letters; companies which submit comment letters are much more likely to use other methods than companies which do not. Other findings suggest that more companies lobby during the stages of the ASB process at which public consultation takes place (e.g., exposure period of a discussion paper) than at the earlier stages of the process (e.g., agenda formation) which are considered in the literature as the stages at which lobbying can be most effective. With respect to the perceived effectiveness of lobbying, companies which lobbied the ASB considered lobbying to be more effective than companies which did not.     

U-type and column-orthogonal designs for computer experiments

U-type designs and orthogonal Latin hypercube designs (OLHDs) have been used extensively for performing computer experiments. Both have good spaced filling properties in one-dimension. U-type designs may not have low correlations among the main effects, quadratic effects and two-factor interactions. On the other hand, OLHDs are hard to be found due to their large number of levels for each factor. Recently, alternative classes of U-type designs with zero or low correlations among the effects of interest appear in the literature. In this paper, we present new classes of U-type or quantitative \(3\) -orthogonal designs for computer experiments. The proposed designs are constructed by combining known combinatorial structures and they have their main effects pairwise orthogonal, orthogonal to the mean effect, and orthogonal to both quadratic effects and two-factor interactions.     

Analysing the Agricultural Costs and Non‐market Benefits of Implementing the Water Framework Directive

Implementation of the Water Framework Directive (WFD) represents a fundamental change in the management of water in Europe with a requirement that member states ensure ‘good ecological status’ for all water bodies by 2015. Agriculture is expected to bear a major share of WFD implementation costs as it is compelled to reduce the emission of diffuse water pollutants. The research outlined here comprises interdisciplinary modelling of agricultural land use, hydrology and consequent water quality effects to consider both agricultural costs and the non‐market recreational use (and potentially non‐use) values that implementation of the Directive may generate. A theme throughout the research is the spatial distribution of the costs and benefits of WFD implementation, which is addressed through the use of GIS techniques in the modelling of agricultural land use, the integration of land use and hydrological models, and the estimation, aggregation and transfer of the economic value of the benefits.
