Technical efficiency in the Spanish agrofood industry

This study estimates frontier production functions with cross-section data lor the Spanish agrofood industry by using deterministic and stochastic parameuic approaches. We compute the individual technical efficiency for each firm, compare the results and explain the relationship between technical efficiency and other relevant quantitative variables. The results indicate that the Spanish agrofood industry has a level of efficiency between 68% and 93%; which means that it is potentially capable of increasing production without increasing its Consumption of inputs. This efficiency level is positively related to factor productivity and unitary labour costs.     

Die Kosten des Klimaschutzes am Beispiel der Strompreise für private Haushalte

Power prices in Germany have been surging since the outset of the new millennium. Among the major reasons for this tendency are newly raised taxes and levies on electricity prices, whose introduction is primarily motivated by climate concerns. Without these taxes and levies, net electricity prices would have remained constant for private households. This article discusses these taxes and levies that have been responsible for the cost increases in private households’ electricity consumption. Most influential have been the feed-in tariffs for renewable energies, above all photovoltaics. According to our calculations, the levy for renewables will further increase in the up-coming years, thereby pushing consumers’ electricity cost once again. Our calculations also show that within the next couple of years, there will be a fierce competition among renewable energy technologies, most notably between photovoltaics and wind power. Politics would be well-advised, therefore, to limit the annual capacity of newly installed solar modules in order to avoid both the explosion of consumers’ electricity bills and strong competition among renewables.     

Do stable strategic time periods exist? Towards new methodological and theoretical insights

This paper investigates a fundamental issue in the current research on strategic groups: the existence or non‐existence of the so‐called ‘stable strategic time periods’ (SSTPs). Our study provides new evidence by adding new methodological and theoretical insights. The research setting is the Spanish banking industry over a 15‐year period, 1983–1997. Unlike all prior longitudinal research that found SSTPs, the multi‐method procedure that we used in this study (i.e. equality of variance and covariance matrix and mean vector of strategic variables and a subsequent grouping analysis performed through the MCLUST) has led us to reject the existence of SSTPs in the industry under study. Based on these original findings, we conclude by suggesting a proposition which should be corroborated in future empirical studies on strategic groups. Copyright © 2007 John Wiley & Sons, Ltd.     

Effects of database choice on international accounting research

Data availability is one of the traditional obstacles confronting researchers carrying out international empirical studies in accounting. In recent years several databases have claimed to offer comprehensive coverage of accounting and financial data of firms worldwide. We analyse whether the choice of database has an effect on the results of empirical studies. We find that the results of a simple empirical adaptation of the Ohlson (1995 ) model for fourteen member states of the European Union change significantly depending on the database chosen (Datastream, Global Vantage, Company Analysis, Worldscope, Thomson Financial, Financials and BvD Osiris). These differences are mainly attributable to differences in the samples across databases. When we match observations across all databases the differences persist but are much less pronounced. Our main conclusion is that database choice matters, as it leads to different results when the same research design is used.     

Board Pay and the Separation of Ownership from Control in U.K. SMEs

This paper examines Board pay for a sample of 571 U.K. SMEs from 1991 to 1995. Approximately half of the sample were closely-held (i.e., owner-managed) firms which allowed empirical testing of models of the relationship between Board pay and ownership from control characteristics. Consistent with their need to align shareholder and manager incentives, the results indicate that the change in nonclosely-held SME Board pay is significantly related to both external market pay comparisons and “benchmark” profits. This contrasts with the empirical results for the closely-held firms where Board pay awards are typically highly sensitive to current total profits but wholly unrelated to external market pay levels.     

Is the Culture of Family Firms Really Different? A Value-based Model for Its Survival through Generations

The current work represents a piece of research on the family firm of the semasiological, interpretive or culture creation type. In it we carry out a comparative analysis of the organizational culture of this type of firm along with firms not considered to be family firms, using as theoretical framework generally accepted theories in business administration, such as the systems, neoinstitutional, transformational leadership, and social identity theories. Our findings confirm the existence of certain elements of culture, especially values and allow us to propose a value-based model to help family firms to survive through different family generations.     

The role of sharing in the circulation of knowledge

One of the points stressed in ‘A new paradigm in the organization of knowledge’, Futures, 26, 1994, pages 781–786, was the determinant role of sharing in the emergence and configuration of the paradigm of the immaterial. We resume the elements suggested then and develop their analysis in three stages: first, by characterizing the operational singularity of sharing; second, by considering its cognitive and disciplinary incidence; and finally, by pointing out its theoretical consequences, namely in what concerns the thematic of rationality.     

The Effect of Market Regimes on Style Allocation

We analyse time-varying risk premia and the implications for portfolio choice. Using Markov Chain Monte Carlo (MCMC) methods, we estimate a multivariate regime-switching model for the Carhart (1997) four-factor model. We find two clearly separable regimes with different mean returns, volatilities, and correlations. In the High-Variance Regime, only value stocks deliver a good performance, whereas in the Low-Variance Regime, the market portfolio and momentum stocks promise high returns. Regime-switching induces investors to change their portfolio style over time depending on the investment horizon, the risk aversion, and the prevailing regime. Value investing seems to be a rational strategy in the High-Variance Regime, momentum investing in the Low-Variance Regime. An empirical out-of-sample backtest indicates that this switching strategy can be profitable, but the overall forecasting ability for the regime-switching model seems to be weak compared to the iid model.     

ERPs as 'technologies-in-practice': social construction, materiality and the role of organisational factors

Enterprise Resource Planning systems (ERPs) often fail to deliver the organisational benefits anticipated. This paper uses Orlikowski's 'technology-in-practice' framework to analyse the impact of an ERP on branch managers in a large bank. While this framework provides important insights into the impact of ERPs, the case also highlights the significance of organisational factors in shaping how users enact technology at work.
