Local water markets for irrigation in southern Spain: A multicriteria approach

Spanish authorities have recently approved a new legislative framework for the creation of local water markets to improve allocative efficiency for this scarce resource. This paper analyses the potential impacts of the policy. A utility function for three groups of farmers was elicited, using a method that does not require interaction with the decision-makers. Utility was measured as a function of the first two moments of the distribution of total gross margin. The utility functions were then used to simulate farmers' responses to changes in the price of water.     

Selling price,financing premiums,and days on the market

Home buyers face the task of trading off selling price and the time required to sell a property. One factor that may affect this decision is the presence of financing premiums. The effects of financing premiums on the time a single-family home remains on the market is examined in this paper. The question is to what extent home sellers are willing to compromise on financing premiums and make concessions to buyers in order to sell their properties more quickly.The study uses a sample of single-family residential homes sold with assumption financing and new conventional financing. The sample covers segments of time when interest rates were relatively low and stable (1975–1976) and when rates were much higher on average and more volatile (1980).The results show that financing premiums were present in selling prices of assumption-financed home sales during the 1975–1976 period and that sellers were able to capture a premium and maintain the same average time on the market as properties with other types of financing. During a period of unfavorable market conditions, such as 1980, the results indicate that home sellers with assumption financing conceded or negotiated away any premium in order to significantly decrease the number of days their properties stayed on the market for sale.     

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.     

Conditional beta pricing models: A nonparametric approach

We propose a two-stage procedure to estimate conditional beta pricing models that allows for flexibility in the dynamics of asset betas and market prices of risk (MPR). First, conditional betas are estimated nonparametrically for each asset and period using the time-series of previous data. Then, time-varying MPR are estimated from the cross-section of returns and betas. We prove the consistency and asymptotic normality of the estimators. We also perform Monte Carlo simulations for the conditional version of the three-factor model of Fama and French (1993) and show that nonparametrically estimated betas outperform rolling betas under different specifications of beta dynamics. Using return data on the 25 size and book-to-market sorted portfolios, we find that the nonparametric procedure produces a better fit of the three-factor model to the data, less biased estimates of MPR and lower pricing errors than the Fama–MacBeth procedure with betas estimated under several alternative parametric specifications.     

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.     

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.
