Estimating the relationship between collateral and interest rate: A comparison of methods

This paper uses a variety of estimation methods to explore the empirical relationship between interest rate and collateral requirements in bank loan contracts. Methods that do not allow for endogenous contract terms detect a positive reciprocal association between interest rate and collateral. Methods that allow for endogenous contract terms point to a strong positive effect of interest rate on collateral but the effect of collateral on interest rate is weaker. This highlights the importance of incorporating the endogenous nature of contract terms in empirical work

3d laser scanning and modelling of the Dhow heritage for the Qatar National Museum

This is the final version of the article. Available from SPIE via the DOI in this record.Curating boats can be difficult. They are complex structures, often demanding to conserve whether in or out of the water; they are usually large, difficult to move on land, and demanding of gallery space. Communicating life on board to a visiting public in the terra firma context of a museum can be difficult. Boats in their native environment are inherently dynamic artifacts. In a museum they can be static and divorced from the maritime context that might inspire engagement. New technologies offer new approaches to these problems. 3D laser scanning and digital modeling offers museums a multifaceted means of recording, monitoring, studying and communicating watercraft in their care. In this paper we describe the application of 3D laser scanning and subsequent digital modeling. Laser scans were further developed using computer-generated imagery (CGI) modeling techniques to produce photorealistic 3D digital models for development into interactive, media-based museum displays. The scans were also used to generate 2D naval lines and orthographic drawings as a lasting curatorial record of the dhows held by the Nationa

Sewn boats in the Qatar Museums collection, Doha: baggāras and kettuvallams as records of a Western Indian Ocean technological tradition

This is the final version. Available on open access from Wiley via the DOI in this recordVernacular sewn boats from southern Iran and Kerala, India, in the collection of Qatar Museums are documented and their construction described. The Iranian baggāras are unique preservations of sewn boats from the Arabian-Persian Gulf, notable for their previously undocumented keel-garboard sewing technique and extensive use of bitumen coatings. Comparison between individual boats enable conclusions to be drawn about the builders’ conception, as well as variation within the type. The Keralite kettuvallams represent an ongoing vernacular tradition that is nevertheless poorly documented or preserved in museum contexts. Construction drawings, naval lines drawings and 3D photogrammetry models are provided for all vessels.University College London-Qatar (UCL-Q)University of ExeterUniversity of Naples ‘l’Oriental

Iran’s last sewn boat? In search of the beach-seining āmele along the Persian Gulf coast of Hormozgan Province, Iran

Recent ethnographic fieldwork along the Persian Gulf coast of southern Iran by the lead author has located probably the last-known sewn vessel in the country – a disused, beach-seining boat known in Bandari as āmele (عامله) and Arabic as ʿāmila (عاملة) in the village of Bostane, in Hormozgan Province. The research has also yielded new information about this type: its former distribution within Hormozgan is established, its function is elucidated, and aspects of its materials and terminology are documented for the first time. The work builds on previous work by the three co-authors documenting sewn vessels of the same type acquired from Iran by Qatar Museums, Doha, in 2012, and reported at that time as baggāra (Persianبگاره; Arabic ارةّبقّ on the basis of museum records

The Effect of Bank Competition on the Bank's Incentive to Collateralize

It has been argued that competing banks make inefficiently frequent use of collateralization in situations where they are better able to evaluate a project's risk than entrepreneurs. We study the bank's choice between screening and collateralization in a model where banks do not have this superior screening skill. In particular, we study the effect of bank competition on this choice. We find that competing banks use collateral less often than a monopolistic bank because competition will intensify if both banks collateralize. Moreover, bank competition is welfare improving if collateralization is rather costly
