Path interdependence in a dynamic two country Heckscher-Ohlin model
Get PDFThe closed economy neoclassical model predicts lung-run convergence in per-capita income. We show, within a neoclassical framework, that international trade among two countries differing only in their initial capital endowment generates long-run income differences. Our results suggests that trade creates opposite incentives to accumulate capital. Transitionally, the returns to investment with trade are smaller for countries initially less endowed with capital as when compared to their autarchic situation, while the reverse happens for those countries most endowed with capital. Thus, countries starting with relatively less (more) capital end, in the long run, with less (more) capital than in autarchy
A THEORETICAL AND EMPIRICAL APPROACH TO THE VALUE OF INFORMATION IN RISKY MARKETS
Get PDFThe theory of the competitive firm under price uncertainty is used to develop a money metric of a producer's willingness to pay for additional information. This concept is extended to the market by formulating ex-ante and ex-post measures of the value of a rational expectations forecast. The empirical feasibility of these measures are demonstrated by application to a simple two equation model of an agricultural market.Marketing,
A MEASURE OF THE VALUE OF INFORMATION FOR THE COMPETITIVE FIRM UNDER PRICE UNCERTAINTY
Get PDFThis paper addresses the problem of measuring the value of information to an agent in an environment where the agent is risk averse and choices are base on the utility of income and personal beliefs about the likelihood of uncertain outcomesRisk and Uncertainty,
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
WORLD TRADE ISSUES AND FOOD SECURITY
Get PDFWhile economic growth has lifted more people from poverty than in any prior period, world market shocks of the 1970s and 1980s have caused a massive realignment in country policies, and future growth in population and income are expected to place heavy burdens on world resources. Recently, it has been suggested that a food crisis may be forthcoming as food production per capita has stagnated, risking a reversal of the long-term decline in the real price of food. This paper focuses on food security in this context, and concludes that a rise in the real price of food is likely, but not of a magnitude to create a food crisis. Nevertheless, those already in poverty may be placed at additional risk of nutritional deprivation. Policies for alleviating this possibility are available, but they entail more than just increasing food production.Food Security and Poverty, International Relations/Trade,
Competition Among Rent Seeking Groups in General Equilibrium
Get PDFA two sector general equilibrium model is developed in which households can influence the government's choice of the relative price of traded goods and the level of public goods supplied to each sector. The model is used to illustrate key problems addressed by the political economy literature, modeling issues that arise, and the nature of insights that can be obtained that traditional approaches cannot discern.General equilibrium, political economy, rent seeking, lobbying, Political Economy,
