The term spread, inflation and economic activity in a simple model of the monetary transmission mechanismMurekezi, Gaju Brigitte 26 March 2008 (has links)
Abstract
This paper presents a simple and transparent framework for the monetary transmission
mechanism of the South African economy based on the model by Rudebusch and
Svensson (1999). This model is extended to consider the long rate and the credit channel
in the transmission mechanism. Firstly, we find that the credit channel plays a significant
role in the transmission mechanism. Secondly, despite the backward looking nature of the
model, impulse responses reveal that the term spread predicts output and inflation in the
South African economy.

Custo e spread da intermediaÃÃo bancÃria no Brasil / Cost and spread of the banking intermediation in BrazilCÃcero Adalberto de Paula Viana 27 April 2004 (has links)
nÃo hà / The Macroeconomic instability lived deeply by Brazil, during decades, motivated practical of the high taxes of interests, provoking significant distortions in the intertemporal allocation of resources in the economy. Passed ten years of the edition of the Real Plan, the success of the monetary politics and the reduction of the level of uncertainties in relation to the country have made possible the fall of the taxes of interests, much even so still are considered between the most raised of the world. The influence of these taxes in the life of the people if negative reflects in the reduction of the capacity of saving and investment, repercurtindo in the sum of credit granted for the financial institutions. The existence of high taxes of interests also finds support in the government, that contributes with a confused and excessive tax burden on the operations of application and captation of resources, as well as the raised level of liability in relation the taxes of reserves of the banks. The necessary administrative costs to the maintenance of the operational activities, the level of present insolvency in the concession of credit and the edge of profit gained for the banks also if configure as determinative factors for the magnitude of these taxes. All these 0 variable significantly affect the process of transmission of resources in the economy, what it provokes the rise of the cost of the money of spread bank clerk and the level of risk of the operations of credit. Inside of this context, this dissertaÃÃo has as objective to define a methodology of calculation of the cost of the money for the credit borrower, of spread gained by the banks and its composoÃÃo, as well as applying a model of evaluation of the level of present proper risk in the practised taxes of application in the process of banking intermediaÃÃo in Brazil. / A instabilidade MacroeconÃmica vivenciada pelo Brasil, durante dÃcadas, motivou a prÃtica de elevadas taxas de juros, provocando distorÃÃes significativas na alocaÃÃo intertemporal de recursos na economia. Passados dez anos da ediÃÃo do Plano Real, o sucesso da polÃtica monetÃria e a reduÃÃo do nÃvel de incertezas em relaÃÃo ao paÃs tÃm possibilitado a queda das taxas de juros, muito embora ainda sejam consideradas entre as mais elevadas do mundo. A influÃncia dessas taxas na vida das pessoas se reflete na reduÃÃo da capacidade de poupanÃa e investimento, repercurtindo negativamente no montante de crÃdito concedido pelas instituiÃÃes financeiras. A existÃncia de taxas de juros elevadas tambÃm encontra amparo no governo, que contribui com uma confusa e exorbitante carga tributÃria sobre as operaÃÃes de aplicaÃÃo e captaÃÃo de recursos, bem como o elevado nÃvel de exigibilidade em relaÃÃo as taxas de reservas dos bancos. Os custos administrativos necessÃrios à manutenÃÃo das atividades operacionais, o nÃvel de inadimplÃncia presente na concessÃo de crÃdito e a margem de lucro auferida pelos bancos tambÃm se configuram como fatores determinantes para a magnitude dessas taxas. Todas essas variaveis afetam significativamente o processo de transmissÃo de recursos na economia, o que provoca a elevaÃÃo do custo do dinheiro do spread bancÃrio e do nÃvel de risco das operaÃÃes de crÃdito. Dentro desse contexto, esta dissertaÃÃo tem como objetivo definir uma metodologia de cÃlculo do custo do dinheiro para o tomador de crÃdito, do spread auferido pelos bancos e sua composoÃÃo, bem como aplicar um modelo de avaliaÃÃo do nÃvel de risco prÃprio presente nas taxas de aplicaÃÃo praticadas no processo de intermediaÃÃo bancÃria no Brasil.

Development of a Low-Fat SpreadHicks, Clair 01 May 1969 (has links)
A stable low-fat water-in-oil emulsion was satisfactorily prepared from milk-fat under laboratory condition. The best product contained 40 per cent fat, 56.8-57.3 per cent water, 0.8 per cent sodium carboxymethyl cellulose, 0.7-1.2 per cent milk solids-non-fat, and 1.2 percent salt. The spread was prepared equally well from butter or high test cream. When the product was made from cream (containing 74 per cent milk-fat) it was necessary to convert most of the globular fat to free fat prior to forming an emulsion. Globular fat in cream was successfully changed to free fat by homogenization at 2500 pounds per square inch or by storing the cream at 5 centigrade for 24 hours. tHe free fat was shock cooled from 41 to 18 centigrade in a swept-surface heat exchanger to give a smooth velvety texture to the milk-fat. The solidified milk-fat was warmed to 22-24 centigrade and emulsified with water containing sodium carboxymethyl cellulose 7HF (manufactured by Hercules Incorporated) and salt. Color and flavoring were added during emulsification.

Likviditetsrisk för aktieoptionerSandberg, Magnus January 2005 (has links)
<p>Målet med denna rapport är att skapa en marknadsmässig prisjustering av en aktieoption som uppvisar en sämre likviditet under en viss tidshorisont. Likviditetsrisken mäts genom att studera skillnaden vid prisbildningen av aktiederivatets olika budsidor. Denna risk ska jämföras med ett rådande marknadspris för varje uppmätning så att en procentuell prisavvikelse erhålls. I den statistiska modellen för en aktieoptions framtida risker studeras flera olika lösenpriser där det existerar omsättning, därmed täcks alla optionsprisers framtida likviditetsrisker. Modellen är uppbyggd med antaganden från den svenska derivatmarknaden för handel. Genomsnittliga värden räknas ut och prisavvikelser för historisk likviditet uppdelas till olika optionsprisnivåer. Modellen kräver vissa antaganden och integreras senare med optionsprismodellen vilket påverkar vissa tekniska aspekter för optionsprisanpassningen. En prisjusteringsmodell med binomialträdets egenskaper för optionsprissättning skapas med antaganden om likviditet och hänsyn till olika optionsprisnivåer. Modellen klarar sedan av att prisjustera en option där en historisk likviditet har uppmätts enligt uppsatta önskemål. Vidare är modellen dynamisk och anpassningsbar för olika derivat gällande marknadens effektivitet, d.v.s. marknadens egenskaper speglas för varje undersökt option. Modellen klarar av olika tidshorisonter. Kritik och diskussion kring vilka effekter som givna antaganden ger upphov till diskuteras och analyseras.</p>

Genetic and Phenomic Determinants of Basal Mechano-sensitivity and Spread of Neuropathic Pain Following Transection of the Infraorbital Nerve in MiceFroimovitch, Daniel 07 December 2011 (has links)
Craniofacial nerve injury occasionally causes spread of mechanical hypersensitivity in humans. We modeled this abnormality by transecting the infraorbital nerve (IONX) in male and female mice of the 23 AXB-BXA recombinant inbred lines and their progenitor strains, comparing their responsivity to 7 applications of a 0.2 gram Von Frey filament to the ears, paws and tail. When normalizing their mechano-responsivity on postoperative days 14 and 21 by the preoperative values, subtracting data of sham-operated from IONX mice, highly contrasting line/strain-specific differences were demonstrated. Similar line/strain-specific variability in the spread of mechano-allodynia to the paws post-IONX was demonstrated in our novel 3 minute place-avoidance paradigm, assessing parameters of mobility on a smooth surface versus a pro-allodynic granular surface. These genetically-controlled, widespread changes in mechano-sensitivity caused by IONX were minimally sexually dimorphic and mapped to intervals on chromosomes 5, 9, and 13. Further analysis is needed to identify the causative genes.
