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.     

Coupon and tax effects on new and seasoned bond yields and the measurement of the cost of debt capital

A model of the tax structure of interest rates is developed and simple approximate expressions relating yield to coupon are derived. The effect on these simple expressions of alternative assumptions about holding period length, expectations of future interest rates, and other factors, is evaluated. It is shown that with recent U.S. yield averages the new-seasoned yield spread varies with the new-seasoned coupon spread as the theory prescribes. It is concluded that new issue yield averages should provide a more reliable measure of the cost of debt capital than is provided by seasoned yield averages.     

PRODUCT MARKET STRUCTURE,CAPITAL INTENSITY,AND SYSTEMATIC RISK: EMPIRICAL RESULTS FROM THE THEORY OF THE FIRM

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.     

LATEST DEVELOPMENTS IN LOCAL GOVERNMENT ACCOUNTING IN SPAIN

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.     

A new measurement procedure for attitudinal research. Analysis of its psychometric and informational properties

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.     

Sulla dominaza stocastical multivariata

Summary In this paper a sufficient condition for multivariate stochastic dominance is proposed. Such a condition is particularly intersesting in the bivariate case because of its simplicity. A numerical example is presented and worked out in detail.

Towards an understanding of the real effects and costs of inflation

Zusammenfassung Zum Verst?ndnis der realen Wirkungen und Kosten der Inflation. — Die traditionelle Ansicht, da\ eine Inflation, weil Geld neutral ist, keine nennenswerten realen Wirkungen hervorbringt, erweist sich nur für eine Volkswirtschaft als ann?hernd richtig, deren Regelungen vollst?ndig inflationssicher sind, d. h. für eine vollindexierte Wirtschaft. Die Realwirkungen erweisen sich aber als um so verbreiteter und schwererwiegend, je mehr bei wirtschaftlichen Regelungen Nominalwerte verwendet werden. Der Aufsatz untersucht nacheinander die Folgen von amtlichen Regelungen auf Nominalbasis (Steuersystem, Definition des steuerpflichtigen Einkommens, Buchführungsmethoden), von privaten Einrichtungen und übereinkünften auf Nominalbasis (Hypotheken, Rentenvertr?ge, Einkommensberechnungen), selbst für den Fall, da\ die Inflation vollst?ndig antizipiert wird bzw. wurde. Anschlie\end werden die Wirkungen einer nicht antizipierten Inflation geprüft, die in den bestehenden nominalen langfristigen Vertr?gen nicht berücksichtigt worden ist, und die Wirkungen einer Ungewissen zukünftigen Inflation. Soweit es m?glich ist, wird versucht, die sozialen Kosten von verschiedenen Realwirkungen abzusch?tzen, obwohl es zur Zeit nicht m?glich ist, die allgemeinen sozialen Kosten der Inflation zu ermitteln.

Résumé Vers une compréhension des effets réels et des co?t d’inflation. — Nous démontrons que la vue traditionelle d’après laquelle l’inflation ne produit pas des effets réels appréciables à cause de la neutralité d’argent est valide pour une économie seulement dont les institutions sont complètement étanche à l’inflation, c’est-à-dire il s’agit d’une économie indexée. Mais nous démontrons que les effets réels deviennent plus et plus diffusés et sérieux comme les institutions de l’économie deviennent presque plus nominales. L’article examine succédamment les conséquences des institutions nominales de gouvernement (le système fiscal, la définition de revenu taxable, la procédure comptable); des institutions privées nominales et des conventions comptables (les contrats de hypothèque et d’annuité, le mesurage de revenu), même si l’inflation est, et a été complètement anticipée. En plus l’article examine les effets de l’inflation pas anticipée et pas incorporée dans les contrats nominaux existants à long terme, et de l’inflation future incertaine. S’il est possible, nous entreprenons l’effort de fixer les co?t sociaux des effets réels différents même bien qu’il ne soit pas possible au moment présent de fixer tous les co?t sociaux de l’inflation.

Resumen Hacia el entendimiento de los verdaderos efectos y costos de la inflatión. — La visión tradicional que la inflatión no produce efectos reales apreciables debido a que el dinero es neutral, es solamente válida en forma aproximada para una economía cuyas instituciones están completamente a prueba de inflatión, p.ej. una economía completamente indexada. Pero se muestra que los verdaderos efectos se generalizarán más y más y serán más serios en la medida que las instituciones de la economía sean más cercanamente nominales. El artículo examina en forma sucesiva las consecuencias de instituciones gubernamentales nominales (sistema de impuestos, definitión del ingreso imponible, procedimientos contables); de instituciones privadas nominales y convenciones contables (hipotecas y contratos de renta anuales, medición del ingreso), incluso cuando la inflatión es y ha sido totalmente anticipada. Examina en seguida los efectos de inflatión no anticipados, que no han sido incoirporados dentro de los contratos de largo plazo existentes, y de inflatión futura incierta. En los casos que fue posible, se hizo un esfuerzo por determinar el costo social de varios efectos reales, aunque en este momento no es posible apreciar los costos sociales totales de la inflatión.
