Competition and risk taking in the banking industry: The case of capital requirements
Full text linkThis article examines how stricter capital requirements affect competition and risk-taking incentives in the banking industry. When banks choose their risk profiles by solving portfolio problems, there is a clear trade-off between competition and risk taking: stricter capital requirements restrict risk taking but soften competition for deposits. The clear trade-off disappears when banks compete in a loan market rather than choose their risk profiles directly. In this case, stricter capital requirements will lead to less risk taking only if they also lead to stronger competition in the loan market
Exclusionary contracts and incentives to innovate
Full text linkThe article considers a situation where several firms have the opportunity to sell an identical product to a set of buyers, and where each seller can invest in R&D to develop a higher quality version of the product in question. I consider the possibility of allowing the sellers to offer exclusionary contracts, prior to deciding how much to invest in R&D. In equilibrium every buyer will sign an exclusionary contract with the same seller. Since all buyers are locked to one seller, only this seller will have an incentive to invest in R&D. Whether or not banning exclusionary contracts increases the aggregate probability of successful innovation depends on the R&D technology. More specifically, banning exclusionary contracts will increase the aggregate probability of innovation and joint surplus of buyers and sellers only when the R&D technology exhibits sufficient diseconomies of scale
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Hump-shaped cross-price effects and the extensive margin in cross-border shopping
No full textThis paper examines the effect of cross-border shopping on grocery demand in Norway using monthly storexcategory sales data from Norway’s largest grocery chain 2011-2016. The sensitivity of demand to foreign price is hump-shaped and greatest 30-60 minutes’ driving distance from the closest foreign store. Combining continuous demand, fixed costs of cross-border shopping and linear transport costs `a la Hotelling we show how this hump-shape can arise through a combination of intensive and extensive margins of cross-border shopping. Our conclusions are further supported by novel survey evidence and cross-border traffic data
Variations on the Author
Full text link“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
Full text linkWe 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
Hump-Shaped Cross-Price Effects and the Extensive Margin in Cross-Border Shopping
No full textThis paper examines the effect of cross-border shopping on grocery demand in Norway using monthly store x category sales data from Norway's largest grocery chain 2012-2016. The sensitivity of demand to the foreign price is hump-shaped and greatest 30-60 minutes' driving distance from the closest foreign store. Combining continuous demand, fixed costs of cross-border shopping, and linear transport costs a la Hotelling, we show how this hump shape can arise through a combination of intensive and extensive margins of cross-border shopping. Our conclusions are further supported by novel survey evidence and cross-border traffic data

Cross-border shopping of alcohol – What is the effect on tax revenue and sales and which products are most affected?
Full text linkWe use COVID-19 border closings and comprehensive store-level data on Norwegian alcohol sales to quantify the effect cross-border shopping of alcohol on sales volume and commodity tax revenue. Effects are large, for instance we estimate that commodity tax revenue for wine is about 20% lower because of cross-border shopping. Using product level data we establish that effects come from across all products rather than just a few, but effects are especially marked for bag-in-box wines. Neither availability of the exact same product in Sweden nor idiosyncratic product-level price difference with respect to Sweden has any marked effect on the impact of cross-border shopping on sales
