Causal relationship and longstanding relationship between foreign exchange and capital markets / Ύπαρξη μακροχρόνιων σχέσεων και σχέσεων αιτιότητας μεταξύ συναλλαγματικής ισοτιμίας και κεφαλαιαγορώνΤζεβελέκα, Αικατερίνη 03 April 2015 (has links)
In this paper we estimate the short-term and long-term relationship between stock prices and exchange rates for the sample of US and Asian markets during the period 2004 – 2014.
Monetary variables include money supply, interest rates, foreign exchange rates, and the consumer price index. All the data are monthly indices and have been examined using multivariate co integration analysis and Granger causality analysis.
The empirical analysis employed provides evidence of a positive co-integrating short- run relationship between these variable with Granger causality found to run from stock prices to the exchange rate during the sample period in Japan. For US, significant relationships were not been established. The results for Japan confirm the conclusion of other studies that stock returns are significant predictors of short – run exchange rate movements especially in period of financial crisis.
We also apply LS model in order to estimate a linear regression. / Στην εργασία αυτή θα εκτιμηθεί η βραχυπρόθεσμη και μακροπρόθεσμη σχέση μεταξύ των τιμών των μετοχών και των συναλλαγματικών ισοτιμιών για το δείγμα των αμερικανικών και ασιατικών αγορών κατά την περίοδο 2004-2014.
Νομισματικές μεταβλητές περιλαμβάνουν την προσφορά χρήματος, τα επιτόκια, τις συναλλαγματικές ισοτιμίες και τον δείκτη τιμών καταναλωτή. Όλα τα στοιχεία είναι μηνιαία και έχουν εξεταστεί σύμφωνα με πολυπαραγοντική ανάλυση και την ανάλυση της αιτιότητας.
Η εμπειρική ανάλυση που χρησιμοποιείται παρέχει απόδειξη της θετικής σχέσης μεταξύ αυτών των μεταβλητών με Granger αιτιότητα από τις τιμές των μετοχών προς την συναλλαγματική ισοτιμία κατά τη διάρκεια της περιόδου του δείγματος στην Ιαπωνία. Για την Αμερική, σημαντικές σχέσεις δεν έχουν τεκμηριωθεί. Τα αποτελέσματα για την Ιαπωνία επιβεβαιώνουν το συμπέρασμα άλλων μελέτών ότι οι αποδόσεις των μετοχών είναι σημαντικοί παράγοντες πρόβλεψης των βραχυπροθεσμων διακυμανσεων των συναλλαγματικών ισοτιμιών,ιδίως σε περίοδο οικονομικής κρίσης.
Μπορούμε επίσης να εφαρμόσουμε το μοντέλο LS, προκειμένου να εκτιμηθεί μια γραμμική παλινδρόμηση.

A systematic review of the relationships between social capital and socioeconomic inequalities in health: a contribution to understanding the psychosocial pathway of health inequalitiesUphoff, E.P., Pickett, K.E., Cabieses, B., Small, Neil A., Wright, J. January 2013 (has links)
Yes / Recent research on health inequalities moves beyond illustrating the importance of psychosocial factors for health to a more in-depth study of the specific psychosocial pathways involved. Social capital is a concept that captures both a buffer function of the social environment on health, as well as potential negative effects arising from social inequality and exclusion. This systematic review assesses the current evidence, and identifies gaps in knowledge, on the associations and interactions between social capital and socioeconomic inequalities in health.
Through this systematic review we identified studies on the interactions between social capital and socioeconomic inequalities in health published before July 2012.
The literature search resulted in 618 studies after removal of duplicates, of which 60 studies were eligible for analysis. Self-reported measures of health were most frequently used, together with different bonding, bridging and linking components of social capital. A large majority, 56 studies, confirmed a correlation between social capital and socioeconomic inequalities in health. Twelve studies reported that social capital might buffer negative health effects of low socioeconomic status and five studies concluded that social capital has a stronger positive effect on health for people with a lower socioeconomic status.
There is evidence for both a buffer effect and a dependency effect of social capital on socioeconomic inequalities in health, although the studies that assess these interactions are limited in number. More evidence is needed, as identified hypotheses have implications for community action and for action on the structural causes of social inequalities.

En ambition var att förstå fenomenet följsamhet utifrån några olika teoretiska perspektiv inom såväl beteende- som samhällsvetenskap. I Delstudie I studerades fenomenet följsamhet i relation till beteendeaspekter avseende patientuppfattningar om styrmekanismer som påverkar den egna hälsan (HLC) och patientupplevda hälsohot och hälsohotens konsekvenser (HB). Denna delstudie bygger på frågeformulär, som besvarades av samtliga patienter innan behandlingsstart. De frågor som mäter patientens uppfattningar om vad som styr den egna hälsan och frågor som mäter patientupplevda hälsohot och hälsoerfarenheter har bearbetats. Definitionerna på följsamhet var dels fullföljd träningsperiod, dels träningsfrekvens. De patienter som genomförde träningen jämfördes med de som avbröt den. De som genomförde träningen studerades dessutom avseende träningsfrekvens. Resultatet i Delstudie I visade att de som avbröt sin behandling, rapporterade större hot av sitt hälsotillstånd (högre smärtintensitet) och större konsekvenser av hälsotillståndet (sämre funktionsförmåga, sämre allmänt hälsotillstånd) än de som genomförde den. Resultatet visade dessutom att de som tränade en gång i veckan eller mer sällan hade värderat vårdsituationens betydelse lägre (HLC), upplevde större hot av sitt hälsotillstånd (högre smärtintensitet), större konsekvenser av hälsotillståndet (större funktionsnedsättning, sämre allmänt hälsotillstånd, större besvärsutbredning), fler hinder för behandlingen (lägre förväntningar) och uppvisade andra demografiska faktorer (yngre individer, fler kvinnor) än de som tränade oftare (HB). I Delstudie II studerades hur patienter själva beskriver anledningen till avbrott i behandlingen, om dessa anledningar kan variera och hur de varierar. Sexton patienter som avbrutit sin behandling intervjuades med öppna frågor. Intervjun inleddes med en fråga om bakgrunden till den sjukgymnastiska behandlingen. De ställdes inför frågor som hade anknytning till genom!örandet av behandlingen och vad de trodde själva om sina besvär. Frågor om patienternas prioriteringar i vardagen ingick, vilka antogs kunna utgöra hinder för behandling under en kortare eller längre tid. Ett tredje område som ingick, rörde deras erfarenheter av patient/sjukgymnast relationen. Intervjuerna analyserades kvalitativt. Analysen i Delstudie II resulterade i att fyra olika beskrivningar av orsaker till avbrott i behandlingen genererades. A) Det var dags att avsluta och gå vidare på egen hand. B) Behandlingen var inte det viktigaste att lägga sin tid på. C) Överenskommelse med sjukgymnasten att avbryta behandlingen på grund av uteblivna resultat. D) Avsaknad av ställningstagande till avbrott i behandlingen. Vid en fårdjupadanalys av kategori D framstod att denna grupp erfar olika former av maktlöshet. Det yttrade sig i beskrivningar av att deras trovärdighet ofta är ifrågasatt, att deras livssituation är en ständig frustration där andra tar de viktiga besluten och där de själva inte har mycket att säga till om, samt att de värjer sig mot att berätta om sina fåreställningar om vad de själva tror besvären beror på och vad man gör åt dem. Vid en jämförelse mellan kategori D och A, B, C har kategorierna A, B och C varierande grad av kontroll i olika situationer medan kategori D saknar kontroll.
