Exchange Rate Regimes and the Extensive Margin of Trade
This paper finds that currency unions and direct exchange rate pegs raise trade through distinct channels. Panel data analysis of the period 1973-2000 indicates that currency unions have raised trade predominantly at the extensive margin, the entry of new firms or products. In contrast, direct pegs have worked almost entirely at the intensive margin, increased trade of existing products. A stochastic general equilibrium model is developed to understand this result, featuring price stickiness and firm entry under uncertainty. Because both regimes tend to reliably provide exchange rate stability over the horizon of a year or so, which is the horizon of price setting, they both lead to lower export prices and greater demand for exports. But because currency unions historically are more durable over a longer horizon than pegs, they encourage firms to make the longer-term investment needed to enter a new market. The model predicts that when exchange rate uncertainty is completely and permanently eliminated, all of the adjustment in trade should occur at the extensive margin.
Gravity Chains: Estimating Bilateral Trade Flows When Parts And Components Trade Is Important
Trade is measured on a gross sales basis while GDP is measured on a net sales basis, i.e. value added. The rapid internationalisation of production in the last two decades has meant that gross trade flows are increasingly unrepresentative of the value added flows. This fact has important implications for the estimation of the gravity equation. We present empirical evidence that the standard gravity equation performs poorly by some measures when it is applied to bilateral flows where parts and components trade is important. We also provide a simple theoretical foundation for a modified gravity equation that is suited to explaining trade where international supply chains are important.
Firms' pattern of trade and access to finance.
This paper summarizes recent advances in the empirical research on firms' learning from trade participation and the role of finance in both starting to trade, surviving in export markets as well as expanding along the intensive and extensive trade margins. It highlights the increased importance of imports, which impacts at firms' performance primarily through relaxed technological constraints by increasing firms's scope of inputs and by lowering their input price index. In addition, imports are shown to boost firms' innovation and introduction of new products, which facilitates firms' decisions to start exporting. Another important aspect that has been highlighted is the essential role of finance in furthering firms'survival and expansion in export markets.exports,learning-by-exports,export expansion, financial constraints, credit crunch;
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
