Get PDFA Critique of Computable General Equilibrium Models for Trade Policy Analysis
Get PDFThe paper will deal in turn with three sets of modelling issues: the question of 'data'; the 'micro' problem of specifying market behaviour, and the. 'macro' issue of 'closing' the models in aggregate. I will conclude with some suggestions for future research. The basic theme of the paper is this: CGE modelling is essentially a conservative or 'neoclassical' scientific endeavour, and exhibits the strengths and weaknesses of neoclassicism. And as for the recent injection of apparently nonneoclassical imperfect competition or industrial organization (IO) concepts into CGE, though, as an 10 specialist myself I certainly welcome this in principle, I have doubts about the usefulness of the practice.International Relations/Trade,
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
Employment in New Zealand
Get PDFExplaining post-war employment and unemployment in New Zealand is problematic for neoclassical economic theory. Up until the late 1970s the economy was overlaid with controls and 'rigidities' of many sorts, interfering with the operation of ‘free' market forces. Yet it delivered virtually zero unemployment without being unusually prone to inflationary pressures. From the 1980s onwards, our economy has been subjected to a remarkable regime of policy 'reform', involving the opening up of markets to overseas competition, the dismantling or emasculating of centralised and/or collectivist institutions, and the adoption of an extreme version of monetarist ideology. Yet throughout these years of actions aimed at fostering ‘free markets', the actual macroeconomic performance of the markets, measured by the mismatch between supply and demand in the labour market (unemployment) has persistently deteriorated, with unemployment rates rising from less than half of one percent as late as 1977 to above 10% in the early 1990s. That is, the more market-oriented we became, the worse the markets performed. How can this be? The research program on which the present paper is a progress report tests hypotheses that can explain how both Keynesian and monetarist orthodoxies miss important aspects of New Zealand reality, and develops a model based on empathy between supply and demand sides of the labour market that is consistent with non-inflationary over-full employment
Oligopoly price discrimination with many prices
No full textThe model of price discrimination in Cournot-Nash oligopoly is extended to the case of many prices, analogous to 1st degree monopoly price discrimination. In the limit all viable customers are served, but the price charged the keenest customers is well below the highest price charged by a monopoly.Price discrimination Oligopoly Cournot-Nash Airlines
Pricing and Competition in Australasian Air Travel Markets
Get PDFThe paper analyses more than ten thousand observations on prices charged for air travel on 1001 flights on eight New Zealand and twenty one trans-Tasman flights observed in 2004 and 2005. The main findings are (i) that routes on which Qantas competes with Air New Zealand tend to have air fares around 20% lower than routes served only by Air NZ; (ii) Emirates and Pacific Blue offer much lower fares across the Tasman but yet cannot achieve substantial markets share implying that (iii) these airlines do not offer much competitive constraint on the pricing of the larger carriers so that (iv) elimination of independent competition between Air NZ and Qantas would be likely to result in air fare increases
Competition Policy for the Trans-Tasman Air Travel Market: the 2005 ACT Decision and its Implications
Get PDFQantas and Air New Zealand are seeking regulatory authorisation for a Tasman Networks Agreement that would in effect cartelise their trans-Tasman operations. They cite in support Reasons given by the Australian Competition Tribunal in its authorisation of their previous application to form a 'Strategic Alliance'. The ACT determined that a cartel-like arrangement between these airlines would not substantially lessen competition across the Tasman because of competition from Pacific Blue and Emirates despite the latter's very small current market share on these routes. This paper examines the ACT's reasons and finds them lacking in economic logic as well as being inconsistent with the facts of airline market competition in Australasia. The paper suggests that the ACT is not an appropriate forum for hearing civil matters such as this and proposes an alternative process based rather on the present procedures adopted by the competition commissions of Australia and New Zealan
