Timing History: The Introduction of Graphical Analysis in 19th Century British Economics

The introduction of time-series graphs into British economics in the 19th century depended on the « timing » of history. This involved reconceptualizing history into events which were both comparable and measurable and standardized by time unit. Yet classical economists in Britain in the early 19th century viewed history as a set of heterogenous and complex events and statistical tables as giving unrelated facts. Both these attitudes had to be broken down before time-series graphs could be brought into use for revealing regularities in economic events by the century's end.

Essays on the Economics of Conflict and Migration

Les conflits civils sont des événements dramatiques qui poussent les individus hors de leurs pays d'origine. Mais si l'émigration était elle-même une force pacificatrice? Dans les deux premiers chapitres, je me suis intéressée à l'impact de l'émigration sur l'incidence des conflits civils dans les pays d'origine. Tout d'abord, je construis un modèle théorique d'équilibre général, dans lequel le niveau de conflit d'équilibre est déterminé par la ratio de combattants dans l'économie. Dans ce modèle, l'émigration décourage les conflits en réduisant les gains d'une rébellion, tout en augmentant le coût d'opportunité des combats. La principale prédiction du modèle est que le conflit diminue avec le niveau du salaire étranger net des coûts de migration. Dans le deuxième chapitre, je teste cette prédiction empiriquement. En utilisant une variable instrumentale, je démontre que l'émigration vers les pays développés diminue l'incidence de guerres civiles dans les pays d'origine. Ces résultats prouvent qu'en ouvrant leurs frontières, les pays d'accueil pourraient contribuer à sauver des vies, aussi bien celles des migrants que celles des habitants restés dans leur pays. De plus, les conflits civils tendent à détruire des sociétés en traumatisant les personnes touchées, augmentant ainsi le risque des conflits futurs. Afin de mieux comprendre ce cercle vicieux et de pouvoir y remédier, le troisième chapitre détermine si les enfants ayant vécu la guerre ont une tendance à être plus violent que des co-nationaux nés après la guerre. L'analyse se concentre sur les demandeurs d'asile en Suisse : Cette population est intéressante puisque l'allocation des demandeurs d'asile entre cantons est aléatoire, ce qui prévient le choix d'un canton avec un taux de criminalité plus élevé. Les résultats démontrent un effet de traumatisme causé par la guerre augmentant ainsi le risque de criminalité dans la vie adulte. Cependant, l'analyse de politiques publiques montre que la mise en place de politiques judicieuses permet d'éviter les conséquences de l'exposition à la guerre. En particulier, en offrant aux nouveaux arrivants l'accès au marché de travail ainsi que des perspectives à long-terme, la Suisse peut éliminer complètement l'effet du traumatisme sur la criminalité.

An analysis of the determinants in economics and business publications by spanish universities between 1994 and 2004

The objective of this study consists, firstly, of quantifying differences between Spanish universities’ output (in terms of publications and citations), and secondly, analysing its determinants. The results obtained show that there are factors which have a positive influence on these indicators, such as having a third-cycle programme, with public financing obtained in competitive selection procedures, having a large number of full-time researchers or involvement in collaborations with international institutions. However, other factors which appear to have the opposite effect were also noted. These include a higher number of students per lecturer or a lower proportion of lecturers with recognised six-year periods.

Research networks and scientific production in Economics: The recent spanish experience

This paper studies Spanish scientific production in Economics from 1994 to 2004. It focuses on aspects that have received little attention in other bibliometric studies, such as the impact of research and the role of scientific collaborations in the publications produced by Spanish universities. Our results show that national research networks have played a fundamental role in the increase in Spanish scientific production in this discipline.

Economics of combined power plant and pyrolysis bio-oil production

There are reasons of necessity in bio-fuel use and bio-energy fast development. It includes the material about bio-energy technologies, applications and methods. There are basic thermodynamics and economic theories. The economic calculation presents the comparison between two combinations. There are boiler plant below 20 MW in combination with ablative pyrolysis plant for bio-oil production and CHP plant below 100 MW in combination with the RTP pyrolysis bio-oil production technology. It provides a material about wood chips and bio-oil characteristics and explains it nature, presents the situation around the bio-fuel market or bio-fuel trade. There is a description of pyrolysis technologies such as ablative and RTP. The liquid product of the pyrolysis processes is bio-oil. The bio-oil could be different even of the same production process, because of the raw material nature and characteristics. The calculation shows advantages and weaknesses of combinations and obtained a proof of suppositions. The next thing, proven by this work is the fact that to get more efficiency from energy project it is good possibility to built plants in combinations.

Opportunistisen sopimusrikkomuksen ongelmasta, erityisesti Suomen vahingonkorvaus- ja rikoslainsäädännön näkökulmasta tarkasteltuna. Law and Economics -näkökulma.

Tämä pro gradu -tutkielma käsittelee opportunistisen sopimusrikkomuksen ongelmaa erityisesti Suomen vahingonkorvaus- ja rikoslainsäädännön näkökulmasta tarkasteltuna. Tutkielman lähestymistapa on oikeustaloustieteellinen (engl. Law and Economics). Opportunistisella sopimusrikkomuksella tarkoitetaan toimintaa, jossa sopimusosapuoli rikkoo sopimuksen tarkoituksellisesti, pyrkimyksenään tällä toiminnalla saavuttaa enemmän hyötyä kuin sopimuksessa pysymällä. Opportunistinen sopimusrikkomus on mahdollista toteuttaa tilanteessa, jossa sopimusasetelma itsessään antaa mahdollisuuden enemmän hyödyn saavuttamiseen rikkomus toteuttamalla kuin sopimus asianmukaisesti täyttämällä. Suomalaisessa vahingonkorvausjärjestelmässä sovelletaan sopimusrikkomusten osalla positiivisen sopimusedun mukaista vahingonkorvausta, joka hyvittää rikotulle osapuolelle sopimussuhteeseen ryhtymisestä syntyneet kustannukset sekä sopimusrikkomuksen johdosta saamatta jääneen tuoton. Positiivisen sopimusedun soveltaminen ei kuitenkaan ole opportunistisen sopimusrikkomuksen ehkäisemiseksi riittävää, sillä opportunistisesti toimiva sopimusosapuoli voi jäädä rikkomuksensa johdosta voitolle vielä sen jälkeenkin, kun kärsineelle osapuolelle on jo positiivista sopimusetua noudattaen korvattu sopimussuhteessa syntyneet kustannukset sekä rikkomuksen johdosta saamatta jäänyt tuotto. Keskeinen ongelma koskien opportunististen sopimusrikkomustilanteiden syntyä onkin juuri vallitsevan sääntelyn liiallinen keskittyminen rikotun osapuolen kärsimän vahingon kompensoimiseen, ei rikkomustilanteiden synnyn ennaltaehkäisemiseen. Suomen vahingonkorvausjärjestelmää tulisi kehittää suuntaan, jossa järjestelmä paremmin ennaltaehkäisisi opportunististen sopimusrikkomustilanteiden syntyä. Common law -oikeusjärjestelmässä käytössä olevan disgorgement principle -suuntaisen ajattelun, jossa korvauksen perustana toimisi rikkomuksella saatu hyöty kärsityn vahingon sijaan, omaksuminen olisi yksi mahdollinen kehityskulku. Olennaista olisi kuitenkin se, että järjestelmää kehitettäisiin suuntaan, jossa rikkomus ei enää voisi tulla rikkojalle kannattavaksi. Opportunistisen toiminnan kannustimet tulisi lainsäädäntöä tarkistamalla poistaa. Tällä olisi sekä sopimusinstituutiota turvaavaa että vaihdantaa edistävää vaikutusta.

Effects of mineral sorting on concentrator design and economics

Ore sorting after crushing is an effective way to enhance the feed quality of a concentrator. Sorting by hand is the oldest way of concentrating minerals but it has become outdated because of low capacities. Older methods of sorting have also been difficult to use in large scale productions due to low capacities of sorters. Data transfer and processing and the speed of rejection mechanisms have been the bottlenecks for effective use of sorters. A fictive chalcopyrite ore body was created for this thesis. The properties of the ore were typical of chalcopyrite ores and economical limit was set for design. Concentrator capacity was determined by the size of ore body and the planned mine life. Two concentrator scenarios were compared, one with the sorting facility and the other without sorting. Comparison was made for quality and amount of feed, size of equipment and economics. Concentrator with sorting had lower investment and operational cost but also lower incomes due to the ore loss in sorting. Net cash flow, net present value and internal rate of interest were calculated for comparison of the two scenarios.

Economics of Power-to-Gas integration to wastewater treatment plant

Solar and wind power produce electricity irregularly. This irregular power production is problematic and therefore production can exceed the need. Thus sufficient energy storage solutions are needed. Currently there are some storages, such as flywheel, but they are quite short-term. Power-to-Gas (P2G) offers a solution to store energy as a synthetic natural gas. It also improves nation’s energy self-sufficiency. Power-to-Gas can be integrated to an industrial or a municipal facility to reduce production costs. In this master’s thesis the integration of Power-to-Gas technologies to wastewater treatment as a part of the VTT’s Neo-Carbon Energy project is studied. Power-to-Gas produces synthetic methane (SNG) from water and carbon dioxide with electricity. This SNG can be considered as stored energy. Basic wastewater treatment technologies and the production of biogas in the treatment plant are studied. The utilisation of biogas and SNG in heat and power production and in transportation is also studied. The integration of the P2G to wastewater treatment plant (WWTP) is examined mainly from economic view. First the mass flows of flowing materials are calculated and after that the economic impact based on the mass flows. The economic efficiency is evaluated with Net Present Value method. In this thesis it is also studied the overall profitability of the integration and the key economic factors.

The death and resurrection of 'economics with psychology': remarks from a methodological standpoint

One of the merits of contemporary economic analysis is its capacity to offer accounts of choice behavior that dispense with details of the complex decision machinery. The starting point of this paper is the concern with the important methodological debate about whether economics might offer accurate predictions and explanations of actual behavior without any reference to psychological presuppositions. Inspired by an exercise of rational reconstruction of ideas, I aim to offer an interpretation of the process of freeing economic analysis from psychology at the end of the 19th century and the contemporary resurrection of behavioral approaches in the late 1980s.
