Determination of cocaine in brazilian paper currency by capillary gas chromatography/mass spectrometry

The presence of illicit drugs such as cocaine and marijuana in US paper currency is very well demonstrated. However, there is no published study describing the presence of cocaine and/or other illicit drugs in Brazilian paper currency. In this study, Brazilian banknotes were collected from nine cities, extracted and analyzed by capillary gas chromatography/mass spectrometry, in order to investigate the presence of cocaine. Bills were extracted with deionized water followed by ethyl acetate. Results showed that 93% of the bills presented cocaine in a concentration range of 2.38-275.10 µg/bill.

Exchange rate volatility and the use of foreign currency derivatives: Impact of 2008 global financial crisis

This thesis examines the impact of foreign exchange rate volatility to the extent of use of foreign currency derivatives. Especially the focus is on the impacts of 2008 global financial crisis. The crisis increased risk level in the capital markets greatly. The change in the currency derivatives use is analyzed by comparing means between different periods and in addition, by linear regression that enables to analyze the explanatory power of the model. The research data consists of financial statements figures from fiscal years 2006-2011 published by firms operating in traditional Finnish industrial sectors. Volatilities of the chosen three currency pairs is calculated from the daily fixing rates of ECB. Based on the volatility the sample period is divided into three sub-periods. The results suggest that increased FX market volatility did not increase the use foreign currency derivatives. Furthermore, the increased foreign exchange rate volatility did not increase the power of linear regression model to estimate the use foreign currency derivatives compared to previous studies.

Currency Carry Trades – Excess Returns and Performance Optimization of G10 Currency Carry Trade Strategies during the Euro Era

This study examines the excess returns provided by G10 currency carry trading during the Euro era. The currency carry trade has been a popular trade throughout the past decades offering excess returns to investors. The thesis aims to contribute to existing research on the topic by utilizing a new set of data for the Euro era as well as using the Euro as a basis for the study. The focus of the thesis is specifically on different carry trade strategies’ performance, risk and diversification benefits. The study finds proof of the failure of the uncovered interest rate parity theory through multiple regression analyses. Furthermore, the research finds evidence of significant diversification benefits in terms of Sharpe ratio and improved return distributions. The results suggest that currency carry trades have offered excess returns during 1999-2014 and that volatility plays an important role in carry trade returns. The risk, however, is diversifiable and therefore our results support previous quantitative research findings on the topic.

Overvaluation trend of the Brazilian currency in the 2000s: empirical estimation

The aim of this paper is to discuss the trend of overvaluation of the Brazilian currency in the 2000s, presenting an econometric model to estimate the real exchange rate (RER) and which should be a reference level of the RER to guide long-term economic policy. In the econometric model, we consider long-term structural and short-term components, both of which may be responsible for explaining overvaluation trend of the Brazilian currency. Our econometric exercise confirms that the Brazilian currency had been persistently overvalued throughout almost all of the period under analysis, and we suggest that the long-term reference level of the real exchange rate was reached in 2004. In July 2014, the average nominal exchange rate should have been around 2.90 Brazilian reais per dollar (against an observed nominal rate of 2.22 Brazilian reais per dollar) to achieve the 2004 real reference level (average of the year). That is, according to our estimates, in July 2014 the Brazilian real was overvalued at 30.6 per cent in real terms relative to the reference level. Based on these findings we conclude the paper suggesting a mix of policy instruments that should have been used in order to reverse the overvaluation trend of the Brazilian real exchange rate, including a target for reaching a real exchange rate in the medium and the long-run which would favor resource allocation toward more technological intensive sectors.

Les répercussions du plan Marshall sur les comportements économiques du Canada durant la période de l'après-guerre

La période de l’après-guerre posa d’importants défis commerciaux à l’économie canadienne. Les années entre 1945 et 1950 furent effectivement marquées par la rupture de son système commercial traditionnel et la recherche d’une stratégie alternative. Le pays dut composer avec un déficit commercial croissant à l’égard des États-Unis, ainsi qu’une chute de ses exportations à destination du Royaume-Uni, ruiné par les années de guerre. Ce déséquilibre commercial qui menaçait d’épuiser les réserves canadiennes de dollars américains reflétait l’écart entre les capacités productives des deux rives de l’Atlantique. Le programme de reconstruction des économies européennes, ou plan Marshall, fut accueilli avec enthousiasme à Ottawa puisqu’il devait non seulement rétablir les marchés du Vieux Continent, mais également faciliter la mise en place d’un réseau multilatéral d’échanges et la libéralisation du commerce international. Les tensions de la guerre froide limitèrent toutefois l’ouverture de ces marchés aux marchandises canadiennes, puisque l’endiguement du communisme commanda une consolidation européenne qui privilégia le démantèlement des entraves aux échanges intra-européens, aux dépens du commerce transatlantique. Les préoccupations de Washington en matière de sécurité collective devaient néanmoins laisser place à une stratégie alternative pour le Canada, en poussant la coopération économique des deux pays, dans le but d’optimiser une production de défense destinée aux pays membres de l’OTAN, dont la demande était soutenue par l’aide Marshall. L’incorporation du Canada dans ce dispositif de défense élargie à la communauté atlantique permit ainsi d’assurer un accès privilégié à ses marchandises sur le marché américain, et par conséquent de progresser vers l’équilibre commercial.
