High inflation economies, especially the Latin American cases like Argentina and Brazil, have ultimately been successful in stabilising their prices using the exchange rate as a nominal anchor. Contrary to conventional wisdom inflation in these cases has not been reduced at the cost of temporary recessions, instead, they have shown positive output effects. Various theoretical explanations of such boom-cycles are discussed and a model generating such an outcome is developed. Some empirical evidence is given by the Brazilian "Real Plan" of 1994. Nevertheless, the medium and long-term effects of such programmes can result in recessions and a resumption of high inflation, although the cases show that such "postponed stabilisation costs" can be overcome by adequate and flexible supply-side policies accompanying the stabilisation programme.

Does an increase of elderly employment cause a decline in youth employment? A simplified view of a demand driven economy would give a positive answer to this question. Econometric studies based on a single equation approach deliver little support for this belief. However, these studies typically suffer from identification problems to which no attention is paid in most cases. We therefore use a general equilibrium framework when trying to quantify these effects. Using yearly and quarterly Austrian labor and gdp data, we estimate two model variants by Bayesian methods: a) a standard equilibrium model where the degree of complementarity between old, young and primary labor is crucial for the sign and strength of the relevant effects and b) a simple, solely demand driven model which always leads to a crowding out of young through an increase in employment of the old. It turned out that the demand driven model is inferior in fitting the data compared to the standard model. Further, the degree of complementarity is estimated to be strong enough to lead to a small positive effect of elderly employment on youth employment.

High inflation economies have ultimately been successful in stabilising their prices using the exchange rate as a nominal anchor. Besides stabilization, these recent examples have shown boom-recession cycles, contrary to what can be expected from (pure) money-based stabilizations. Various theoretical explanations of such boom-cycles are discussed and a model of aggregate supply and demand generating such an outcome is developed. There the boom dynamics depend mainly on a slump in real interest rates and wage flexibility. (author's abstract) / Series: Department of Economics Working Paper Series

This thesis is a study conducted in collaboration with the engine performance group atHusqvarna AB. The study focuses on engine stability of smaller two stroke handheld enginesrunning on E10 (10% ethanol mixture in gasoline). The reason for the study is the new EUproposition that by 2020 all fuel must have 10 % renewable fuel content. To meet thisproposition Husqvarna has evaluated E10 and found that the engine stability of smaller twostroke engines are affected in a negative way by the fuel.The study focuses on events occurring prior to the combustion and mainly the carburetor. Theobjective for the thesis is to seek what contribution the events occurring prior to thecombustion have to the engine stability and find simple and implantable solution to improvethe stability with regards to the carburetor.The study has been conducted in three different work packages, system understanding to buildknowledge of how the carburetor operates, fault finding to seek potential attributes that canaffect the stability and fault mode analysis to seek why the attributes affect the stability.Furthermore, all the attributes found has been tested and validated on the engine to seek theircontribution to the stability.The conclusion made of the thesis is that with simple and implementable improvements of thecarburetor the engine stability could be increased with 40 %. A total of five differentattributes were found to affect the stability of the engine. Furthermore, a very detailedexplanation of how the carburetor operates and components inside the carburetor has beenestablished during the thesis.

The scope of this thesis is to show how the use of maps in political and scientific arguments functions as a mediator between ideological discourse and the physical landscape. This is done by studying three maps displaying the same geographical region but from different times and with different motifs. The maps were studied by operationalizing the French Sociologist Bruno Latour’s concept of immu-table mobiles into a methodological toolset.The thesis shows that the cartographic tradition of the Swedish state throughout the 20th century func-tioned as an immutable mobile that ideological actors could use to form political or scientific argu-ments. An almost trivial point to make. However, the problem is the great distance between state and the place, which in this case is about 1400 kilometers. Thus, the map allows a remote power relation-ship. As the state-owned immutable mobiles were extracted, they were interpreted by the politicians and scientists ideological perspectives. The ideological interpretations were then used in government propositions and reports and thus resulted in actual political decisions that affected the physical land-scape.The creation of Abisko National Park is one example of how this process can look. The park was instigated with a specific set of political goals to be achieved. The political and scientific actors used the immutable mobile that is the map and formed a proposition with it. The act of instigating and upholding the Abisko Valley as a national park is thus a manifestation of both state presence, its supremacy over territory as well as its contemporary ideological context. Moreover, it would be im-possible to instigate a park without the use of maps to define its borders. The planning and ratification of Transnational Road 98 can be seen as another example of the same thing, but with a different contemporary ideology as background.The thesis results in an explanation about what the maps role is in a stately place making process. Additionally the thesis shows what happens over time as different ideological embodiments in the landscape conflict with each other because of their different visions of how the landscape should be used and by whom. / Uppsatsens syfte är att försöka hur kartor fungerar som en länk mellan politisk diskurs och det fysiska landskapet. Detta görs genom att studera tre kartor som avbildar samma område men vid olika tidpunkter och med olika motiv. Kartorna studeras genom en operationalisering av den franske sociologen Bruno Latour’s teori om ’immutable mobiles’.Uppsatsen visar att den statliga kartografiska verksamheten under 1900-talet i Sverige producerade immutable mobiles som sedan kunde avläsas av aktörer och som i sin tur kunde använda dem för att understödja deras politiska och vetenskapliga argument. En tillsynes trivial poäng. Problemet är dock avståndet i mellan den centraliserade makten och platsen som i detta fallet är ca 1400 kilometer. Kartorna möjliggör alltså en maktrelation trots det stora avståndet. Allt eftersom de statligt ägda kartorna var hämtade, tolkades de av aktörernas ideologiska perspektiv. Dessa tolkningar låg sedan till grund för politiska beslut som sedan resulterade i faktiska ingrepp i landskapet.Formerandet av Abisko nationalpark används i uppsatsen som ett exempel på hur denna process fungerar. Parken skapades med ett specifikt set av ideologiska motiv. De politiska aktörerna använde statliga kartor för att utforma sin proposition. Formerandet av parken är således en manifestation av både statlig närvaro, statlig kontroll över landskapet och ett ideologiskt artefakt. Det vore därtill omöjligt att skapa parken utan en karta för att definiera dess gränser. Planerandet och konstruerandet av mellanriksväg 98 mellan Kiruna och Narvik har analyserats på ett liknande sätt, dock med en annan ideologisk bakgrund.Uppsatsen resulterar i en möjlig förklaring till vad kartorna har för roll i en statlig platsskapande och landskapsförändrande process. Vidare så försöker uppsatsen förklara hur olika ideologiska tolkningar av landskapet kan hamna i konflikt med varandra över tid på grund av inkompatibla ideologiska motiv.

A gasoline direct injection engine was set-up to operate with a dynamometer in a test cell. Test cycle and emissions measurement procedures were developed for evaluating the regulated and non-regulated gaseous emissions. Equipment and techniques for particulate matter measurements were adapted for use with the gasoline direct injection engine. The particulate matter emissions produced by the engine were compared between two different fuels; gasoline and E10 (10% ethanol and 90% gasoline). The gaseous emissions generated by the engine when it was run on gasoline and E30 (30% ethanol and 70% gasoline) were also compared. Particle number decreased with E10 for hot start conditions, while the opposite was observed for cold start conditions. Particulate matter emissions were found to track with acetylene and ethylene emissions.

Thesis (M. Com.(Economics)) -- University of Limpopo, 2017 / The relationship between unemployment, exchange rate and inflation has been a subject of debate for many years. Given the fact that South Africa is faced with a very low economic growth rate, inflation rate which is likely to go beyond the upper band of 6 percent and a high level of unemployment, policy makers are often faced with the trade-off between unemployment and inflation rate in the country. The purpose of this study is to determine the relationship between exchange rate, unemployment and inflation in South Africa. The study employed Johansen cointegration procedures and the vector error correction model (VECM) to capture the relationship between the variables. The Engle-Granger causality test was also employed to analyse causality amongst the variables. The results of Johansen cointegration test indicate that there is a long-run equilibrium relationship between the variables. The VECM also confirmed the existence of short-run equilibrium relationship between the variables. The nature of the relationship indicates that there is a significant negative relationship between unemployment and inflation in South Africa. This implies that policy makers are been faced with the trade-off between these two variables. The results further indicate that inflation is positively related to exchange rate, meaning a depreciation of the Rand (South African currency) in the foreign exchange market will feed to inflation in the home country. Furthermore, it is also indicated that unemployment is positively related to exchange rate. Meaning, a depreciation of the Rand in the foreign exchange market increases the level of unemployment in South Africa. All the results appeared to be significant. Policies aimed at lowering unemployment and inflation rate are recommended. It is also recommended that policy makers in South Africa take measures to improve the quality of education, skills training and steps to increase the labour intensity of production.
