Orientador: Eduardo Strachman / Resumo: Em um ambiente de globalização financeira, a taxa de câmbio se coloca como uma variável de relativa importância para uma economia. A justificativa para isso está centrada no fato de que ela representa um dos principais preços relativos de uma economia e, portanto, estudos que buscam descobri a sua determinação, os seus movimentos e a sua dinâmica estão constantemente presentes na literatura econômica. A emergência sobre essa temática surgiu após o fim do acordo de Bretton Woods em 1973, no qual o seu fim resultou em mudanças na arquitetura do sistema monetário e financeiro internacional, modificando, entre várias coisas, o relacionamento dos países com as suas respectivas taxas de câmbio. Em alguns países o regime de câmbio flutuante foi adotado em detrimento do regime de câmbio fixo, e com isso as taxas de câmbio passaram a apresentar um comportamento altamente volátil, o que despertou a curiosidade sobre este fato. O comportamento volátil das taxas de câmbio somado a propagação da globalização financeira, ocasionou o processo de “financeirização” das taxas. Este processo estreitava a relação do câmbio com os fluxos de capitais de curto prazo, além de permitir ganhos especulativos com a variação cambial. Com essa nova realidade, alguns estudos emergiram com o objetivo de explicar a nova dinâmica cambial. É neste contexto que surgiu a abordagem pós-keynesiana de determinação cambial, que traz como um dos fundamentos a criação do Modelo Mental. O modelo mental seria um esquema...

The end of Bretton Woods agreement in 1973 led to changes in the international financial architecture, such as the ones observed in the relationship between a country with its exchange rate. As some countries chose the floating Exchange rate regime instead of the fixed one. the exchange rates of the following years presented a highly volatile behavior. This behavior added to financial globalization, growing demand for liquid assets, and deep markets, caused a financialization of the Exchange rate. This process strengthened the relation of the Exchange rate to short-term capital flows. In addition, it permitted speculation profits from the exchange variation. In this same period, lots of theories and models were formulated trying to explain this new outline. Among them, there is the post Keynesian approach of exchange rate determination. According to it, agents’ expectations and short-term capital flows are the driving force of currency movements. Thus, this approach created a mental model which delineates the development of those expectations. The complete mental model has three phases; indicators, base factors, and processes, and it will be used as part of this paper methodology. As this study is a descriptive and explanatory, its methodological procedures were divided in two parts. First, there is a descriptive statistical analys...

Cette thèse met en évidence l’aspect macroéconomique du degré de report du taux de change sur les prix dans la zone euro. Nous utilisons un large éventail de méthodes économétriques récentes afin de fournir des mesures robustes sur la transmission du taux change ainsi que sur ses déterminants macroéconomiques. Notre recherche révèle le rôle prépondérant des facteurs macroéconomiques dans le déclin récent du degré de report. Une conséquence directe de ce résultat est que la baisse du taux de transmission du change n’est pas nécessairement un phénomène structurel, et il peut être ainsi résolu par des politiques macroéconomiques conjoncturelles. Par exemple, l’adoption de régimes de politique monétaire plus crédibles avec l’engagement de maintenir une inflation faible joue un rôle important dans la réduction de la sensibilité des prix aux variations du change. Ceci est particulièrement valable pour les pays dont les politiques macroéconomiques sont historiquement laxistes. Ainsi, la poursuite de politiques économiques solide et lisible au sein de l’UEM peut être un outil efficace pour réduire le degré de report du taux de change / This thesis highlights the macroeconomic aspect of the exchange rate pass-through to domestic prices in the euro area countries. We use a wide range of up-to-date econometric methods in order to provide robust measures of the rate of pass-through as well as to shed further light on its macro determinants. The main finding of our research is the prominent role of macroeconomic forces in driving the recent declin of the transmission of currency movements. A direct consequence of this result is that the lowering in the rate of pass-through is not necessarily a structural phenomenon and it may be solved via macroeconomic policies. For instance, the shift to a more stable monetary policy conditions with credible and anti-inflationary regime would reduce the sensibility of prices to exchange rate changes. This is especially true for countries with historically poor macroeconomic policies. Thus, a better macroeconomic management with a sounder set of policies within the EMU may be an effective tool for reducing the degree of pass-through

[pt] Os investimentos em infraestrutura, públicos e privados, são notoriamente essenciais à competitividade de uma economia. Hoje, o Brasil sofre com diversas limitações em políticas voltadas ao setor de infraestrutura, que contribuem de forma direta para que os produtos e serviços brasileiros sejam mais caros. Uma destas limitações reside nas condições de financiamento em projetos desta natureza. A possibilidade de se obter parte do financiamento em moeda estrangeira seria uma alternativa agradável aos investidores, no entanto, os traria um risco cambial. Este trabalho analisa uma proposta de mecanismo de cobertura cambial a ser oferecido no âmbito de parcerias público-privadas, que disponibiliza aos investidores uma opção de proteção contra a variação cambial real. Este mecanismo é interpretado como uma garantia com características de uma opção, uma vez que assume valores em função da variação da taxa de câmbio. Neste sentido, este trabalho buscou avaliar e precificar estas garantias cambiais a partir de uma abordagem por opções reais, adotando para isso dois modelos de estimação para a taxa de câmbio, um passeio aleatório com drift neutro e o modelo GARCH-M. Os resultados obtidos em ambos os modelos mostraram-se favoráveis ao governo, no entanto é possível afirmar que a adoção de uma garantia cambial com estas características ofereceria claramente maior risco ao poder concedente do que a iniciativa privada. Assim, uma forma de lidar com esse risco seria estabelecer limites com relação ao valor do financiamento a ser obtido e uma margem de segurança para o poder público em torno do fator de remuneração presente na garantia. / [en] Infrastructure investments, both public and private, are essential to the competitiveness of any economy. Currently, Brazil has several limitations in policies that are applied to the infrastructure sector, which directly contribute to make Brazilian products and services more expensive. One of these limitations arises from the financing requirements of projects of this nature. Obtaining part of the financing requirements in foreign currency would be an alternative for many investors; however, it would bring them the foreign exchange rate risk. This paper analyzes a proposal for a foreign exchange hedging mechanism to be offered in public-private partnerships scope, which provides investors with an option to hedge against the real foreign exchange fluctuation. The mechanism is perceived as a guarantee with has option-like characteristics, as its value varies as a function of the foreign exchange rate. Thus, this work sought to evaluate and price these foreign exchange rate guarantees based on a real options approach. Two exchange rate models were adopted to estimate future levels: a random geometric stochastic drift-free model and the GARCH-M model. The results obtained by both models indicated that use of this guarantee is favorable to the government. However it is possible that the proposal of a foreign exchange guarantee with these features could present a greater risk to the government than to the private partner. Therefore, one way to deal with this risk would be to establish a limit on the total amount obtained through the financing and a safety margin regarding the guarantees remuneration factor.

Magister Commercii - MCom / This study estimates the impact of the real exchange rate’s performance on economic growth in South Africa from 1990 to 2016 based on quarterly data. A review of the literature reveals that the real exchange rate can have either a positive or a negative effect on economic growth. The empirical analysis began with testing for stationarity of the variables by applying the Augmented Dickey-Fuller (ADF) and Phillips Peron (PP) tests. This was followed by the co-integration test of the model. The unit root test results show that all variables except the exchange rate were integrated at order one, that is I (1), while exchange rate volatility is integrated at order zero that is I(O). Also, the co-integration analysis indicated that variables are co-integrated. Employing the Vector Error Correction Model (VECM) technique to estimate the results, the relationship between real exchange rate and economic growth was estimated. Findings further show that in the short run, economic growth is positively responsive to the real exchange rate while in the long run, a negative relationship exists between the two variables. The results in the short run suggest that the exchange rate hurts economic growth. A 1% point increase in the real exchange rate (RER) causes a reduction in economic growth by 379 per cent. A rise in the RER affects the trade balances between exports and imports, which results in more imports in the country than exports and the devaluation of the rand stipulates imports in the short run, which leads to the gross domestic product to increase. The study recommends that the South African Reserve Bank (SARB) Monetary Committee, together with the South African government, should develop a policy that will pursue a prudent monetary policy. A stabilise real exchange rate will enhance the economic activities that will attract foreign direct investment (FDI) and create an environment conducive to investment that will boost economic growth of South Africa.

In this study, the authors examined the relationship between crude oil price and the Swedish and Norwegian stock markets. Using linear regression models the authors found that the Swedish stock market and Norwegian stock market both have a positive relation with crude oil price. This supports the hypothesis that crude oil price has a positive impact on Norwegian stock market, since Norway is an oil exporting country. However, this result contradicts a hypothesis of a negative relationship for an oil importing country like Sweden. The authors also looked into the relationship between exchange rates (Swedish krona and Norwegian krone) and oil price, which reveals that oil price is significantly negatively correlated with Swedish krona and Norwegian Krone. The study contributes with evidence from underexplored regions of the world.

Globalization is a fact in a lot of businesses today, something that is also relevant in the real estate industry. The currency differs depending on where investments are made and as a result of this real estate investors also face currency risks in addition to all other real estate related risks they already need to manage. The management of currency risk can have different forms, and the purpose of this thesis is to find out how, if and why real estate investors, especially Swedish, hedge this risk. To create an understanding of the issue, a summary of some theories on the currency market and real estate market can be found in the thesis. Only a small amount of research exists on the subject in Sweden and the theories are mainly from foreign studies and the currency risk management from other business sectors. These theories, combined with the research questions, have formed the questions for the interviews this study is made of. Debt in the local currency of where the investment is made can be seen as a natural hedge for the currency risk. Reduced loan-to-value (LTV) ratios from banks for real estate investments have led to a situation where loans, which can cannot be used to the same extent. That makes it more interesting to find out which other instruments are being used to avoid the currency risk and if the real estate investors wants to avoid it at all. The purpose of this thesis is to find the answers to these questions. The interviewed consultancy firms and banks as well as the investors themselves state that the currency risk is a risk that should not occur in Swedish real estate investments on markets with a different currency. The reason for this is that the real estate assets should be the primary focus of the business. To hedge this risk, bank loans and currency futures are the most frequently used instruments by Swedish real estate investors. / Globalization is a fact in a lot of businesses today, something that is also relevant in the real estate industry.

In this paper, we examined the effects of real effective exchange rate (REER) changes on the Zambia´s trade balance, and whether the Marshal-Lerner condition (M-Lerner condition) and the Jcurve effect are satisfied in Zambia following the depreciation of the Zambian Kwacha (ZMK) against the U.S. dollar. Using annual time series data from 1990 through to 2019, the Johansen cointegration test results show that there is a long run relationship between the trade balance, the real effective exchange rate, the Zambia's GDP growth, the world´s GDP growth, and the Zambia´s terms of trade. A standard trade balance model was employed to estimate the long run and short run relationships between the trade balance and the variables in the trade balance model. The results from the trade balance show that the depreciation of the ZMK against the U.S. dollar improves the trade balance in the long run though the results could not validate the M-L condition since the coefficient value of REER was found to be far much less than unity (1). The results further uncover that the world´s GDP growth and the terms of trade both have a significant positive effect on the trade balance in the long run. The Zambia´s GDP growth was found to be statistically insignificant. In the short run, the results from the trade balance model show that the effects of the depreciation of the ZMK against the U.S. dollar on the trade balance were statistically insignificant, thus not consistent with the J-curve effect. The results from the Error Correction Model (ECM) on the other hand show that about 6.3% of the disequilibrium in the Zambia´s trade balance model is corrected every after one year.

With the shift to a system of floating exchange rates among major currencies in 1973, there was a shift of emphasis from the external balance to the exchange rate determination. Attempts have been made to explain the behavior of the exchange rate both theoretically and empirically over the last 20 years. Most models could not explain what happened, as in the 1980s, when the exchange rate moved a lot. Alternative models based on different approaches give different explanations and suggest different policies. This study examines the implications of the models to see what light the empirical results shed on the issues. Results of this study indicate that both monetary and real factors are important in explaining the behavior of the exchange rate, but the results generally support the view of the monetary approach.

In this study, a total of nine regression models were performed with three different dependent variables, nine independent variables, in three different country groups, to find out the relationship between crypto adoption and remittances, monetary uncertainty and financial inclusion. The results show a statistically significant relationship between increased crypto adoption and historical exchange rate volatility in both high- and low-income countries. Peer-to-peer exchange trade volume in low-income countries also seems to be affected by the proportion of the population that sends remittances. Based on these findings, it seems like cryptocurrencies are not only seen as asset substitution, i.e., something to risk diversify the investment portfolio with, it also seems to be used as a currency substitution.
