Sparti elektroninės komercijos plėtra ir augimas natūraliai sąlygojo modernių, online aplinkai pritaikytų atsiskaitymo, mokėjimo sistemų atsiradimą. Itin svarbu tai, kad technologijų tobulėjimo pasėkoje ne tik eksponentiškai išaugo perduodamos informacijos kiekis, tačiau pakito pačios informacijos prigimtis – ji pati savaime, per se, tapo ekonominę vertę turinčiu objektu. Vartotojų noras saugiai atsiskaityti internete įtakojo, kad „online“ aplinkoje mažėja naudojimas tokių tradicinių atsiskaitymo priemonių kaip mokėjimo kortelės. Interneto vartotojai vis rečiau pasitiki šiuo mokėjimo įrankiu, kadangi vartotojai, pateikdami pardavėjui savo mokėjimo kortelės duomenis, susiduria su neteisėta šių duomenų panaudojimo rizika. Šiame darbe pateikiamas siūlomas dalinai prijungties režime veikiančios elektroninių pinigų cirkuliacijos sistemos, skirtos mažiems ir vidutiniams mokėjimams, modelis, besiremiantis sukurta Payword mikromokėjimų sistemos koncepcija. / Fast developing and growing of e-commerce determined the coming of modern payment systems. Intention of users to pay safely on the internet impacted the decrease of use of traditional payment system such as credit cards. It’s started to look for and design alternative ways of payment, such as smart cards systems or systems using software for saving monetary value. Traditional payment systems currently used by most e-commerce sites are not suitable for high volume, tiny valued transactions. There is a need of payment system that is cost effective, secure and easy to use. The purpose of this work is to propose a model of semi-online electronic money circulation system for small and average payments, which is based on a concept of R. Rivest and A. Shamir created micropayment system called Payword. The proposed model’s architecture and protocol are explained in detail. To increase performance of the system there was done a research to find out which hash algorithm and electronic signature algorithm is most suitable for the proposed model.

This study looks at the price mechanism of the digital quasi-currency bitcoin. Through statistical analysis of secondary data a probable significant results regarding correlation and regression between price and different independent variables have been established. The final analysis is pointing towards network effects being a part of the determinants for the crypto-currency’s price. Complimentary to the quantitative study explained above, an implementation of hermeneutic analysis based on secondary theoretical sources, journalistic opinion and a professional qualified judgment has aided the author and study in conceptual understanding. This interpretation has semantic character, and takes a Socratic kickoff regarding the nature of bitcoin as a financial instrument. The analysis runs back and forth throughout the course of the study and finally intertwines with qualitative results in the discussion. It is the author’s impression that a significant dimorphism surrounds bitcoin, calling for a conceptual differentiation leading to practical rethinking. The study takes the shape of a case-study conducted over four months. The author’s location during the process of writing was Stockholm Sweden, but the gathered data is of transnational character. / Den här studien tittar på prismekanismen hos den digitala kvasi-valören bitcoin. Genom statistisk analys av sekundärdata har sannolikt signifikanta resultat angående korrelation och linjärregrission mellan pris och olika oberoende variabler ettablerats. Den slutgiltiga analysen pekar mot att nätverksvariabler är delaktiga i avgörandet av krypto-valutans pris. Komplimentärt till den kvantitativa studen förklarad ovanför så har en implementation av hermeneutisk analys basserad på sekundära källor, journalistiska åsikter och ett professionellt kvalifiserat uttalande hjälpt författaren samt studien i dess konceptuella förståelse. Denna tolkning har semantisk karaktär, och tar Sokratisk avstamp gällande bitcoins natur som ett finansielt instrument. Analysen går fram och tillbaka genom uppsatsens gång, för att slutligen sammanvävas med de kvantitativa resultaten i uppsatsens diskussion. Det är denna förfatares intryck att en signifikant dimorphism omsluter bitcoin och kallar för en konceptuel differensiering som leder till praktiskt nytänkande. Studen tar formen av en fallstudie som genomförts om loppet av fyra månader. Författarens plats genom skrivandeprocessen var Stockholm Sverige, men den samlade datan har transnationell karaktär.

Titel: Bankrevisorers yrkesutövning i det förebyggande arbetet mot penningtvätt Syfte: Studien syfte är att öka förståelsen samt förklara hur externa och interna bankrevisorer arbetar förebyggande mot penningtvätt inom banksektorn. Syftet besvaras genom att undersöka hur penningtvättslagen tillämpas i bankrevisorers yrkesutövning, hur det arbetet förhåller sig till god revisionssed samt om berörda parter upplever ett förväntningsgap gällande bankrevisorers ansvar att upptäcka finansbrott, såsom penningtvätt. Metod: Studien har tillämpat en kvalitativ forskningsmetod för att studera hur externa och interna bankrevisorers yrkesutövande förhåller sig till det förebyggande arbetet mot penningtvätt. Detta har genomförts med hjälp av tio stycken semi-strukturerade intervjuer med externa och interna bankrevisorer samt berörda parter för att kunna bidra med ytterligare perspektiv. Resultat och slutsats: Ett resultat som studien kan påvisa är att varken interna eller externa bankrevisorer rapporterar misstänkt penningtvätt direkt till Finanspolisen. Interna bankrevisorer rapporterar misstänkt penningtvätt till Compliance-funktionen samt att externa bankrevisorer rapporterar misstänkt penningtvätt till företagets VD eller styrelse i första hand. Studien finner stöd i att god revisionssed är en betydande faktor i det förebyggande arbetet mot penningtvätt för externa och interna bankrevisorer. Det finns även ett förväntningsgap eftersom externa och interna bankrevisorer kan göra mer i deras yrkesutövning för att förebygga penningtvätt inom banksektorn. Förslag till vidare forskning: En liknande studie som enbart fokusera på banker som sysslar med kontanthantering samt att Revisorsnämndens perspektiv beaktas. Studiens bidrag: Studien bidrar till att kartlägga externa och interna bankrevisorers ansvar i det förebyggande arbetet mot penningtvätt inom banksektorn. Studiens resultat bidrar till företagsekonomisk forskning genom att öka förståelsen av samarbetet mellan samtliga parter för att förebygga penningtvätt inom banksektorn. Nyckelord: Bankrevisorer, internrevision, externrevision, penningtvätt, PTL, penningtvättslagen, god revisionssed / Title: Bank auditors professional practice in the prevention of money laundering Aim: The aim of this essay is to increase understanding and explain how external and internal bank auditors work to prevent money laundering in the banking sector. The aim is answered by examining how the Money Laundering Act apply in their professional practice, how the work relates to the generally accepted auditing standards and if concerned parties are experiencing a gap of expectations regarding bank auditors responsibility of detecting financial crimes such as money laundering. Method: The essay has applied a qualitative research method to study how external and internal bank auditors professional practice relates to the prevention of money laundering. This has been achieved by executing ten semi-structured interviews with external and internal bank auditors and other concerned parties to contribute additional perspectives. Results and Conclusions: The result of the essay shows that neither external nor internal bank auditors report suspected money laundering directly to the Finance Police. Internal bank auditors report suspected money laundering to the Compliance department and the external bank auditors report suspected money laundering to the company CEO or board in firsthand. The essay shows that the generally accepted auditing standards are a significant factor in the prevention of money laundering for external and internal bank auditors. The result shows a gap of expectations, the external and internal bank auditors can contribute more in their professional practice to the prevention of money laundering in the banking sector according to concerned parties. Suggestions for future research: A similar study focusing solely on banks with cash management including the Auditor Board´s perspective. Contributions of the essay: The essay helps to identify external and internal bank auditors responsibility in the prevention of money laundering in the banking sector. The results contribute to business research by increasing understanding of the cooperation between concerned parties to prevent money laundering in the banking sector. Keywords: bank auditors, internal audit, external audit, money laundering, PTL, the Money Laundering Act, generally accepted auditing standards

Cette thèse étudie les déterminants de l'adoption des services financiers par téléphonie mobile et ses conséquences sur les comportements financiers individuels dans les pays en développement. Elle est composée de trois chapitres/articles auto-référents. Le premier chapitre étudie l'adoption croissante des services financiers par téléphonie mobile dans les pays en développement en distinguant mobile money (utilisation du mobile pour accéder à des services financiers) et mobile banking (services financiers liés à un compte bancaire accessibles par téléphonie mobile) et en confrontant l'Afrique Sub-Saharienne aux autres pays en développement. L'étude montre que le mobile money est plus répandu que le mobile banking dans les pays en développement mais plus encore en Afrique Sub-Saharienne. Les déterminants de son adoption sont liés aux facteurs macroéconomiques, à l'étendue des services financiers et des activités d'intermédiation du secteur bancaire dans chaque pays et surtout de l'ampleur des transferts d'argent des migrants. Le chapitre 2 analyse l'impact de l'adoption du mobile money sur le comportement individuel d'épargne à partir de données d'une enquête de terrain menée au Burkina Faso en 2014. En distinguant l'épargne selon qu'elle est constitué pour des événements prévisibles ou non, les résultats montrent que le mobile money a un impact favorable sur l'épargne lorsqu'elle est destinée à faire face à des événements imprévisibles et plus particulièrement à d'éventuels problèmes de santé. Les résultats plus précis révèlent que ce sont en fait les groupes défavorisés à qui le mobile money permet effectivement de développer cette capacité d'épargne, la sécurité et la possibilité de transferts d'argent dans la sous-région apparaissent comme les principaux facteurs explicatifs. Le chapitre 3 exploite ces données d'enquête en étudiant l'impact de l'adoption du mobile money sur l'utilisation des services financiers traditionnels (formels et informels). L'analyse montre que les utilisateurs du mobile money le privilégient pour effectuer leurs dépôts grâce aux avantages qu'il apporte en termes d'accès, de coût, de liquidité et de confidentialité par rapport aux services financiers traditionnels. Cependant, l'étude révèle que l'utilisation du mobile money renforce l'accès des usagers des services financiers informels et des groupes défavorisés à la fois aux banques et aux caisses d'épargne. / This dissertation investigates determinants of mobile financial technology adoption and its consequences on individual financial behaviors in developing countries. It is structured around three chapters/self-contained papers. The first chapter explores the growing adoption of mobile financial technology in developing countries by distinguishing mobile money (use of a mobile phone to access financial services) from mobile banking (access of banking services using a mobile phone) and setting Sub-Saharan Africa against other developing countries. The results show that mobile money adoption dominates mobile banking in developing countries especially in Sub-Saharan Africa. Determinants of its adoption include macroeconomic factors, outreach of financial services, banking sector intermediation activities and especially remittances. The second chapter analyzes the impact of mobile money adoption on individual saving behavior by using individual-level survey data that we designed and conducted in 2014 in Burkina Faso. By distinguishing saving for predictable events from that for unpredictable events, the findings show that mobile money has a positive impact only on saving for unpredictable events especially saving for health emergencies. Precisely, the results show that disadvantaged groups who use mobile money are likely to save for health emergencies, and that safety and the availability of money transfers within the sub-region appear as factors that may explain the use of mobile money to save for health emergencies. The third chapter exploits the same survey data to analyze the impact of mobile money adoption on the usage of traditional (formal and informal) financial services. The results show that mobile money is preferred for deposits over traditional financial services because of the convenience that it provides in terms of relative access, risk, liquidity and privacy. Interestingly, the results reveal that the use of mobile money brings participants in informal deposit mechanisms and disadvantaged groups toward banks and credit unions.

L’étude de la confiance dans le domaine des sciences de l’information et de la communication revêt une importance capitale pour cette discipline au carrefour des autres. Elle permet d’affiner mais aussi de compléter les connaissances pour une meilleure appréhension des phénomènes informationnels et communicationnels. La confiance du fait de sa nature jugée trop théorique, reste très peu mobilisée dans les recherches comme une variable explicative des phénomènes de l’information et de la communication.L’objectif de ce travail est de mesurer le niveau de confiance des utilisateurs dans « orange money ». Ce service de transaction monétaire par téléphone mobile fait désormais partie de la gamme des services proposés à la population malienne par la société de télécommunication Orange Mali. En vue d’atteindre cet objectif, un questionnaire a été administré auprès de 309 citadins dans le district de Bamako (Mali).Les résultats issus du traitement et de l’analyse des données collectées montrent que, les répondants ont un niveau élevé de confiance dans les transactions monétaires sur téléphone mobile. Cependant, il ressort de ces résultats une méfiance généralisée des participants à l’enquête à donner leurs informations personnelles à Orange Mali. L’ensemble de ces résultats sont interprétés dans un chapitre dédié.Le présent de thèse s’articule autour de dix chapitres. Il se compose de trois grandes parties dont la première est consacrée à la présentation des concepts théoriques de la confiance, le contexte économique et social. La deuxième partie se focalise sur l’analyse des données et l’interprétation des résultats de l’étude. La troisième partie est focalisée à la mise en perspectives des principaux résultats de ce travail. / The study of trust in the field of information and communication science is of paramount importance in this discipline at the crossroad of others research field. It helps to refine and to supplement the knowledge to a better understanding of informational and communicational phenomena. Trust due to it theoretical aspects, is rarely mobilized in research as an explanatory variable in information and communication sciences.The objective of this work is to measure the level of trust of "Orange Money" users. This money transfer system based on mobile phone is now part of the range of services offered by the company of telecommunications Orange Mali to Malian populations. In order to achieve this, a questionnaire was administered to 309 citizens in the district of Bamako, the main city of Mali.Results from the processing of collected data show a high level of confidence of users in monetary transactions by mobile phone. However, the result shows a general distrust of survey participants to give their personal information to Orange Mali. All these results are interpreted in a dedicated chapter.The present thesis focuses on ten chapters organized into three parts: the first is devoted to the presentation of theoretical concepts on trust, economic and social context. The second part focuses on the analysis, processing and interpretation of data collected on our field survey. And finally, in the third part, we try to put into perspective the results.

Bakgrund: Under 2015 gjordes upphandlingspliktiga inköp för cirka en sjättedel av Sveriges BNP vilket visar på de betydande pengabelopp som upphandlingsförfarandet innefattar. Samtidigt är det också ett stort antal organisationer som är berörda av upphandlingslagstiftningen där bland annat Sveriges sekundärkommuner ingår som en del av organisationerna. Tidigare studier på global nivå har visat på bristande regelefterlevnad gentemot upphandlingslagstiftning men att studera fenomenet i en svensk kontext har inte tidigare låtit sig göras. Det finns därför både samhällsrelevans såväl som teoretisk relevans att studera fenomenet närmare i en svensk kontext. Syfte: Syftet med vår studie är att bidra med ökad förståelse för hur regelefterlevnaden hos svenska sekundärkommuner har sett ut gentemot lagen om offentlig upphandling och dess grundläggande principer. För att öka förståelsen vill vi synliggöra faktorer som har påverkat regelefterlevnaden hos sekundärkommunerna. Metod: Denna studie utförs genom en innehållsanalys med både kvantitativa och kvalitativa inslag. En ansats tillämpas där både positivism och hermeneutik återfinns i olika delar av studien. Gällande empiriskt underlag så bygger det på sekundärdata i form av revisionsrapporter som sekundärkommunerna publicerat. Slutsats: Studiens resultat konstaterar att regelefterlevnaden har varit bristfällig i motsvarande 75 procent av de svenska sekundärkommunerna. De faktorer som påverkat regelefterlevnaden mest har varit interna regler och rutiner, ansvarsfördelning och uppföljning. Motsatsvis har utbildning och kompetens samt förekomst av en central databas ej visat sig ha samma påverkan på regelefterlevnaden. / Background: In 2015 procurement affairs were made for about one sixth of Swedish BNP which is pointing at the considerable amounts of money that the procurement procedure involves. Simultaneously there is also a large amount of organizations who are affected by the procurement legislation where secondary municipalities of Sweden is one of these organizations. Earlier studies on a global basis have been providing evidence pointing at lack of compliance towards procurement legislation but studying of this phenomenon in a Swedish context has not previously been done. It is therefore relevant to study this phenomenon closer, both socially as well as theoretically, in a Swedish context. Purpose: The purpose of our study is to contribute to a further understanding of how compliance in secondary municipalities of Sweden have been towards The Public Procurement Act and its basic principles. In order to contribute to this further understanding, we want to make factors visible which have affected compliance in secondary municipalities. Methodology: This study is performed through a content analysis using both quantitative and qualitative elements. An abductive approach is applied were both positivism and hermeneutic can be found in different parts of the study. Regarding the empirical basis it is built up by secondary data which is based on audit reports that secondary municipalities have published. Conclusion: The results of the study indicate that compliance towards The Public Procurement Act have been insufficient in 75 percent of the Swedish municipalities. The factors that have affected the compliance most have been internal rules and procedures, division of responsibility and follow-up of the procurement process. On the contrary, education and competence as well as the presence of a central database have not shown to have the same effect on compliance.

En 1965, Allais proposa une reformulation tout à fait originale de la théorie quantitative de la monnaie. Il s’agit de la théorie Héréditaire et Relativiste (HR) de la demande de monnaie. Apparue une décennie après la reformulation friedmanienne et la publication du modèle de Cagan (1956) relatif aux hyperinflations, cette théorie n’a pas réussi à se frayer une voie dans le champ de l’analyse monétaire. Plusieurs raisons ont concouru au non succès de cette théorie dont notamment son cadre conceptuel tout à fait étrange par rapport aux approches alors dominantes. L’objet de notre thèse est d’interroger l’apport de la théorie HR en tant que reformulation de la théorie quantitative et ce par rapport à la question de la stabilité de la demande de monnaie.Cette thèse est composée de trois parties. La première partie développe certains préludes nécessaires à l'analyse de la théorie HR (partie I). Les deux dernières parties contiennent les deux principaux résultats de notre travail. Le premier est que la théorie HR constitue une reformulation « ontologique » de la théorie quantitative, qui passe par la considération du temps psychologique-le temps tel que ressenti par l’ensemble des agents économiques (Partie II). Le second résultat est que la théorie HR, en tant que théorie macroéconomique, est grosse d’un changement paradigmatique qui fait écho à celui introduit en physique par la théorie de la relativité : pour certains phénomènes monétaires, la théorie HR substitue à l’explication par des relations causales entre agrégats une explication par la seule déformation psychologique du temps (Partie III). / In 1965, Allais proposed an original restatement of the quantity theory of money. It is the Hereditary and Relativistic (HR) theory of the money demand. Published a decade after Friedman’s restatement and Cagan’s model of hyperinflations, the HR theory remained unknown. Many reasons contributed to the lack of success of this theory, one of which is related to its conceptual framework which is incongruous with the standard approach. The HR theory is based upon the notion of time relativity from a psychological point of view, and the idea that the behavior of economic agents is conditioned by a hereditary effect of past events.Our thesis aims to investigate the contribution of the HR theory as a restatement of the quantity theory with regard to the question of the stability of money demand.The thesis is composed of three parts. The first part contains necessary preludes to the analysis of the HR theory (Part I). The second and the third part contain the two main results of the thesis. The first one is that the HR theory represents an ontological restatement of the quantity theory based on the notion of “psychological time”- time as experienced by the collectivity as a whole (Part II). The second result is that the HR theory, as a macroeconomic theory, contains a paradigmatic shift which echoes the one introduced in physics by the theory of relativity: in the HR theory, an explanation of some monetary phenomena using the psychological distortion of time is substituted to the explanation through causal relations between aggregates (Part III).

This thesis maps development of money illusion through the history of economic thought and analyzes relevance of the concept in these days. The story begins in 1928 with Irving Fisher, who saw money illusion as a failure to perceive changes in purchasing power of money. Different notion was developed by John Maynard Keynes when he proposed a non-homogeneous labor supply. In the 1970s, the success of rational expectations theory led to a dismissal of the original theories of money illusion and Tobin's critique revealed also an inconsistency of the Keynesian notion. Since then, money illusion lost its position in the mainstream economic science. The modern theories were, however, able to align money illusion with rational expectations and provided the phenomenon with a psychological framework. Money illusion became described as a tendency to think in nominal rather than real terms. While the concept was revived as a part of behavioral and New Keynesian economics, the question of its aggregate effects remains as the Keynes' inconsistency have not been resolved until these days.

Cette thèse étudie la proposition 100% monnaie, telle qu’elle fut formulée aux États-Unis dans les années 1930 par Henry Simons (l’auteur principal du « Plan de Chicago »), Lauchlin Currie et Irving Fisher notamment. L’essence de cette proposition est de divorcer la création de monnaie des prêts de monnaie : les dépôts servant de moyens de paiement seraient soumis à 100% de réserve en monnaie légale, conférant à l’État un monopole de la création monétaire. Cette idée de réforme étant régulièrement sujette à confusion, nous entreprenons de clarifier son concept et d’étudier ses principaux arguments. Au chapitre 1, nous montrons que le 100% monnaie ne saurait être considéré comme un simple avatar des idées de la « Currency School » : contrairement à l’Acte de Peel de 1844, il ne contient en soi aucune règle d’émission, laissant ouvert le débat « règle ou discrétion ». Au chapitre 2, distinguant entre deux grandes approches du 100% monnaie, nous montrons que celui-ci n’implique nullement d’abolir l’intermédiation bancaire basée sur les dépôts d’épargne. Au chapitre 3, nous analysons, à travers les travaux de Fisher, l’objectif principal du 100% monnaie : celui de mettre fin au comportement procyclique du volume de monnaie, causé par le lien de dépendance entre création monétaire et prêts bancaires. Au chapitre 4, nous étudions un autre argument du 100% monnaie : celui de permettre une réduction de la dette publique, en rendant à l’État l’intégralité du seigneuriage – argument souvent critiqué, dont nous montrons qu’il n’est pourtant pas infondé. Alors que le 100% monnaie suscite un regain d’intérêt depuis la crise de 2008, il nous a paru fondamental de clarifier ces questions. / This thesis studies the 100% money proposal, such as it was formulated in the United States in the 1930s by Henry Simons (the main author of the “Chicago Plan”), Lauchlin Currie and Irving Fisher in particular. The essence of this proposal is to divorce the creation of money from the lending of money: deposits serving as means of payment would be subjected to 100% reserves in lawful money, awarding the state a monopoly over money creation. Because this reform idea is regularly subject to confusion, we endeavour to clarify its concept and study its main arguments. In chapter 1, we show that the 100% money proposal ought not to be viewed as a mere avatar of the “Currency School” ideas: contrary to Peel’s Act of 1844, it contains no issuing rule by itself, leaving open the debate “rule or discretion”. In chapter 2, distinguishing between two broad approaches to the 100% money proposal, we show that it does not imply abolishing bank intermediation based on savings deposits at all. In chapter 3, we analyse, through Fisher’s works, the main objective of the 100% money proposal: that of putting an end to the pro-cyclical behaviour of the volume of money, caused by the dependency relationship between money creation and bank loans. In chapter 4, we study another argument of the 100% money proposal: that of allowing a reduction of public debt, by returning the totality of seigniorage back to the state—an oft-criticised argument, which, as we show, is not unfounded however. While the 100% money proposal has been arousing renewed interest since the 2008 crisis, we thought it was fundamental to clarify these issues.
