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.  相似文献

The article considers the social services supply in the Spanish area of Valencia. The objective is double. First the authors analyse what describes the partnership between public sector and NPO in this area, by using a systemic conception of the social services sector where three main functions can be identified (financing, production and distribution, and regulation). Secondly they search for theoretical arguments explaining this partnership principle. This second section is mainly based on the NPO approach.  相似文献

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.  相似文献

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.  相似文献

Product market concepts from industrial organization economics are integrated with financial valuation models of the firm to investigate relationships among systematic risk, capital intensity, and product market power. The theory of the firm facing uncertain input and output prices is extended to provide empirical models. Empirical results coincide with hypotheses derived from the theoretical model and pose questions about traditional single period hypotheses found in the finance literature.  相似文献

This paper provides an analysis of the present situation concerning local government accounting in Spain following recent reforms introduced in the early nineties. It presents a picture of the main features of Spanish local finance—budgeting and accounting, the measurement focus, and the basis of accounting—and analyses the financial reporting system adopted by Spanish municipalities. This is followed by a critical review of several weak points in the reform which in the author's view will encourage further developments.  相似文献

Since measurement errors have strong effects in all relationships (statistical or otherwise) studied, there is an increasing interest in the data quality, which is the major justification for this research. This paper aims to present a new measurement procedure, the letter scale, which avoids many of the problems connected with the response modalities traditionally used in attitudinal research, especially the ordinal categorical scales. This paper analyzes the error composition of the scores obtained with this new measurement procedure. The validity of the procedure is also analyzed and the observed variance is assessed to determine which part of the observed variance is “valid”, which part is random error (attenuating relationships) and which is correlated error (magnifying relationships). Structural equation models will be used to provide estimates of the measurement quality: (i) Reliability, (ii) Construct validity, method effect and residual variance. In addition, this letter scale is evaluated under another different perspective, Information Theory measures are also used to assess the amount of information transmitted. The relative merits of this new measurement procedure as opposed to other common response modalities will be discussed in both cases.  相似文献

This article addresses the contribution to hedonic modeling of a nonparametric approach based on artificial neural network (ANN) regressions. ANNs provide consistent estimates for the hedonic price of each attribute and permit a number of hypotheses on the hedonic price relationship to be tested nonparametrically. In particular, we exploit results by Stinchcombe and White (Econom Theory 14:295?C324, 1998) in order to carry out misspecification testing in linear and semiloglinear hedonic models. The same approach directly applies to testing misspecification of any parametric specification for the hedonic relationship. A nonparametric significance test for the variables in the hedonic model is also proposed. The test extends the approach developed by Racine (J Bus Econ Stat 15(3):369?C378, 1997) in kernel-based nonparametric testing to ANN-based inference. The finite sample performance of the proposed tests is analyzed through Monte Carlo experiments, and simulation-based algorithms for computation of the null distribution of the tests are proposed. Then, the performance of three classes of regression models??linear, semi-log, and ANNs??applied to hedonic price modeling in a Spanish regional housing market is compared. Our results indicate the presence of nonlinear behavior, as predicted by economic theory, with the ANN-based tests detecting statistically significant evidence of misspecification??both in the linear and the semilog specifications??and ANN regressions providing moderate improvement of predictive performance.  相似文献
