Explaining the process of change taking place in legal rules and social norms: The cases of institutional economics and new institutional economics
1995
This paper deals with the phenomenon of institutional change and has been conceived as an attempt to answer the following question: Can we retain theimage of institutional change contained in a theory when we replace a methodological foundation on which the theory was built by a different and alternative one? For an answer to be developed, special attention is paid to the contributions made by institutional economists (IE) and those made by transaction cost—new institutional economists (NIE). The question clearly shows that it is a paper on applied methodology rather than a survey on institutional change contributions. Because of that, its main purpose is not to increase our knowledge about…
Local development through social and territorial innovation: an exploratory case study
2017
This investigation aims to examine innovation in a selected successful Portuguese social venture (The Cooperative Terra Chã) and to analyse the extent to which innovative social ventures are able to contributeto local development. Specifically, the paper highlights the activities developed by the social organization in response to the needs of particular (micro) segments of society and illustrates which key factors triggered thesuccess of the examined social initiative. A case study methodology is used to describe the distinctive characteristics and strategies pursued by the managers of the social venture and to establish the links between the opportunities for social innovation and the ter…
Human capital and income inequality revisited
2021
This paper revisits the relationship between human capital and income inequality, using an updated data set on human capital inequality and a novel database on earnings inequality. We find an inver...
A Test of Covariance-Matrix Forecasting Methods
2015
Providing a more accurate covariance matrix forecast can substantially improve the performance of optimized portfolios. Using out-of-sample tests, in this article the author evaluates alternative covariance matrix-forecasting methods by looking at: (1) their forecast accuracy, (2) their ability to track the volatility of a minimum-variance portfolio, and (3) their ability to keep the volatility of a minimum-variance portfolio at a target level. The author finds large differences between the methods. The results suggest that shrinking the sample covariance matrix improves neither the forecast accuracy nor the performance of minimum-variance portfolios. In contrast, switching from the sample …
Roy Bhaskar’s Critical Realism and the Social Science of Marxian Economics
2018
This article supports claims that critical realism philosophy of science, as refounded in the hands of Roy Bhaskar, offers valuable knowledge enhancing insight into the advancement of Marx’s research program. However, it maintains that key principles set out by Bhaskar have not been adequately assimilated by those working with critical realism in the field of Marxist studies. When they are properly considered, they point to the necessity of reconstructing Marx’s corpus on a divergent basis from the conventional form it has assumed since the codification of “Marxism” by Karl Kautsky in the late nineteenth century as an overarching theory of history or historical materialism, wherein Marx’s e…
Estimating Engel curves under unit and item nonresponse
2010
SUMMARY This paper estimates food Engel curves using data from the first wave of the Survey on Health, Aging and Retirement in Europe (SHARE). Our statistical model simultaneously takes into account selectivity due to unit and item nonresponse, endogeneity problems, and issues related to flexible specification of the relationship of interest. We estimate both parametric and semiparametric specifications of the model. The parametric specification assumes that the unobservables in the model follow a multivariate Gaussian distribution, while the semiparametric specification avoids distributional assumptions about the unobservables.

L’analisi della conversazione istituzionale: applicazioni e prospettive
2015
La Conversation Analysis si occupa del parlato quotidiano, di interazioni comunicative qualsiasi, tra amici o sconosciuti, tra commesso e cliente, insegnante e allievi, terapeuta e paziente. Gli esempi delle applicazioni potrebbero essere infiniti, dato che la conversazione e le sue varianti "istituzionali", come l’intervista o il dibattito, costituiscono la forma di comunicazione più immediata e diffusa. Nell'articolo l’autrice introduce alla Analisi della Conversazione, ne illustra gli aspetti di base, ne mostra le applicazioni alle interazioni comunicative istituzionali e propone una sinergia interdisciplinare a partire da un nucleo sociologico con indicazioni operative e prospettive per…
Sampling properties of the Bayesian posterior mean with an application to WALS estimation
2022
Many statistical and econometric learning methods rely on Bayesian ideas, often applied or reinterpreted in a frequentist setting. Two leading examples are shrinkage estimators and model averaging estimators, such as weighted-average least squares (WALS). In many instances, the accuracy of these learning methods in repeated samples is assessed using the variance of the posterior distribution of the parameters of interest given the data. This may be permissible when the sample size is large because, under the conditions of the Bernstein--von Mises theorem, the posterior variance agrees asymptotically with the frequentist variance. In finite samples, however, things are less clear. In this pa…
Pedagogía política y drama escolar protestante. El Masaniello de Christian Weise
2023
La revuelta de Nápoles de 1647 encabezada por el pescador Tommaso Aniello (Masaniello) suscitó intensas reacciones en todo el continente europeo. A su vez, la reflexión sobre la política y la razón de Estado adquiría cada vez mayor relevancia a partir de la segunda mitad de siglo XVII. El campo literario no se quedó atrás y algunos intelectuales vieron en estos acontecimientos históricos la oportunidad para expandir sus modelos pedagógicos en los teatros escolares protestantes: el uso de la historia como método de enseñanza de la política, de la retórica y de la religión al mismo tiempo. Uno de estos autores fue Christian Weise (1642-1708) quien, tomando como fuente algunas de las crónicas …
La Educación Comparada como método para la mejora y la visualización de la Educación Musical
2018
El detrimento de la presencia de la Educación Musical en los diferentes niveles educativos en España es un hecho contrastado. Si nos fijamos en el transcurso de las numerosas leyes educativas que se han desarrollado en nuestro país podemos observar como poco a poco la música ha ido perdiendo relevancia. La principal causa de este hecho se deriva, entre otras, de la capitalización de la educación. Para combatir este efecto una de las mejores maneras es analizar cómo se van redefiniendo en otros países y regiones los diferentes sistemas educativos haciendo frente a estas adversidades. Un modo de crear estos espacios en los que compartir conocimiento y crear puntos de unión en relación con un …
