Prior Adjustment: An Extension of the Frisch-Waugh Theorem to the Method of Two-Stage Least Squares
No full textThe problems of seasonal adjustment and other forms of prior adjustment have seldom been integrated into a general framework of estimation. A well-known result, due to Frisch and Waugh, has been used to demonstrate how linear seasonal influences might be treated in the context of the general linear statistical model. In this paper, the author establishes a proposition that one form of prior adjustment is consistent with two different estimating techniques that are in common use
Time-Series for the British Post-War Economy
No full textOne product of the author's recent investigation into the determinants of real fixed capital formation in the post-war british Economy was the following set of time-series. In this paper, the author tells us how the extension of the series beyond the range of the other series resulted in the inclusion of a period during which the rates of the two principal taxes could not be aggregated in a simple linear manner, and the expression for the aggregate tax-rate had to be modified. This break is indicated in the text
Investment Functions: Which Production Function?
No full textIn this paper, an approximation is suggested whereby the alternative C.E.S. form can be fitted as a number of additional corrections to the final expression associated with the Cobb-Douglas form. Some numerical results are tabulated, and these indicate that, for the British Economy at least, the specification of a Cobb-Douglas form for the production function is inappropriate
Corporate Taxation in the United States: The Post-War Experience
No full textThe area of corporate taxation has stimulated a great deal of debate in both academic and political circles. On the political side, there have been those who argue that a corporation is only a legalistic creation and should not be regarded as a 'flesh-and-blood' person. This paper shall be concerned only with Federal taxes on corporations, although it is recognized that the system of dual sovereignity has raised questions of constitutionality in taxation areas between the Federal and state governments. A result of this has been the developing importance of the judicial branch of government in the taxation field, along with the legislative branch, as an interpretive body of no small significance
Fixed Capital Formation in the British Economy, 1956-1965
No full textFew econometric analyses dealing with aspects of the British post-war economy were available. In 1968, a study sponsored by the Brookings Institution was compelled to acknowledge the absence of any econometric investigation of the British system of investment incentives. In the following sections of this paper, this omission is remedied, and some empirical reults are tabulated for a group of models applied to data derived for one decade of the post-war British economy
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Quarterly Models of Wage Determination: Some New Efficient Estimates
No full textThe concept of stable Phillips curves and their economic implications have been the subject of a series of disputes in recent years. Since Phillips introduced his simple disequilibrium model,empirical research in the field of wage determination has indicated a wide spectrum of explanatory variables which expands and contracts almost randomly in published studies. Apart from this difficulty in specification, the intertemporal instability of estimated coefficients for Phillips curve variants is particularly disturbing. In addition, the theoretical bases for many of these variants are unclear, and several economists have participated in a neo-classical counter-attack on the existence and stability of Phillips curves from a theoretical viewpoint. The objectives of this paper are to examine the consequences of certain invalid statistical procedures which are employed in many of these studies and to provide some empirical evidence of their effect. In particular, we focus attention on the implications of the aggregate procedure which provides the basis for the use of a "four quarter overlapping change" representation of the dependent variable in quarterly studies of wage determination and, also, for the use of moving averages of explanatory variables
