Beyond sea, sun and fun in Rio de Janeiro: understanding exchange students motivations and interests

O objetivo deste estudo é compreender o que leva estudantes de intercâmbio ao Rio de Janeiro, quais são suas motivações e interesses que influenciam na escolha dessa cidade, um destino pouco tradicional para intercâmbios, que recebe um crescente número de intercambistas de países desenvolvidos. Também apresentamos uma discussão mais ampla sobre a educação internacional do século 21, posicionando programas de intercâmbio como uma das possíveis iniciativas para a internacionalização de instituições de ensino superior. Para responder essa questão, 20 estudantes de 11 países foram entrevistados. Os resultados indicam que existe muito mais no Rio de Janeiro além do sol e das belas praias. Há uma grande variedade de interesses que explicam porque estudantes de intercâmbio escolhem esse destino. O clichê sobre sol, praia e carnaval se manifestou em diversas respostas, no entanto, nunca como principal fator. Intercambistas se interessam pela cidade por diversos motivos além das atrações turísticas, como aprender português, melhorar o currículo e estar em uma economia emergente. Recomendações para a internacionalização de instituições de educação e uma agenda de pesquisa para o desenvolvimento desse tópico são apresentadas na parte final.

Exchange rate misalignments, interdependence, crises, and currency wars: an empirical assessment

Este trabalho tem por objetivo comparar metodologias distintas para cálculo de desalinhamento cambial além de testar a hipótese se as taxas de câmbio dos diversos países sofrem influencia apenas dos seus próprios fundamentos ou também da taxa de câmbio e dos fundamentos de outros países. Estas hipóteses consistem, respectivamente, na ausência ou na existência de interdependência entre os diversos países. Para realizar tal tarefa utilizam-se duas estratégias empíricas. A primeira baseia-se em avaliar se um modelo multivariado de séries de tempo usualmente utilizada na literatura de desalinhamento cambial com dados apenas do próprio país em análise pode ser melhorado através da adição de variáveis relacionadas a outros países usando o algoritmo proposto por David Hendry e co-autores. A segunda estratégia consiste em estimar um panel longo com as variáveis utilizadas para estimar desalinhamento cambial e testar formalmente a hipótese de ausência de interdependências. Os resultados sugerem que em ambas estratégias existe evidência de existência de interdependência. Esta ocorreria mais por conta de fatores ligados ao curto prazo, ou seja, o que explicaria o valor da taxa de câmbio de um país no longo prazo seriam seus próprios fundamentos enquanto no curto prazo fatores externos poderiam causar desvios

Exchange students in Brazil: some factors behind its choice - empirical evidences from a Brazilian school

O Brasil sempre foi um lugar conveniente para se visitar em termos de cultura, diversão e entretenimento. No entanto, este estudo visa o lado educacional do país, particularmente, os estudantes estrangeiros que escolhem o Brasil para programas de intercâmbio. Fins e razões por trás das escolhas dos estudantes foram identificados através de pesquisas quantitativas e qualitativas, juntamente com a revisão da literatura já existente. A pesquisa primária foi feita por meio de entrevistas com estudantes de intercâmbio já no Brasil. Os dados coletados foram analisados e são apresentados de forma estatística, juntamente com a representação gráfica. O seguinte estudo apontou que os denominados “turistas” e, assim chamados, “money seekers”, serem os principais fatores por trás da escolha de estudantes. A pesquisa também mostra que os alunos mais satisfeitos foram os que escolheram o Brasil por causa da qualidade da universidade sede, assim como para explorar as perspectivas de emprego, juntamente com iniciar uma carreira no Brasil.

Temporal causality between the exchange rate and the trade balance : the case of Brazil

The paper assesses the impact of intemational relative prices and domestic expenditure variables on Brazil' s foreign trade performance in the first half of the 1990s. It has been argued that the appreciation of the Real since 1994 has had a detrimental impact of the country's trade balance. However, using temporal precedence analysis, our results do not indicate that the trade balance is strongly affected by intemational rei ative prices, such as the exchange rate. Instead, domestic expenditure variables appear to be more powerful determinant of the country' s trade performance in recent years. Granger and error correction causality techniques are used to determine temporal precedence between the trade balance and the exchange rate in the period under examination. Our findings shed light on the debate over the sustainability of recent exchange rate-anchored macroeconomic stabilisation programmes, which is a topic that has encouraged a lot of debate among academics and practitioners.

Does monetary policy stabilize the exchange rate following a currency crisis?

This paper provides evidence on the relationship between rnonetary policy and the exchange rate in the aftermath of currency crises. It ana1yzes a large data set of currency crises in 80 countries in the period 1980 to 1998. The rnain question addressed is: can rnonetary policy significantly alter the probability of reversing the post-crisis undervaluation through nominal appreciation rather than higher int1ation? We find that tight rnonetary policy facilitates the reversal of currency undervaluation through nominal appreciation rather than inflation. When the econorny is also facing a banking crisis, depending on the specification, tight rnonetary policy rnay not have the same effect.

Sovereignty, exchange rate and the Euro crisis

This paper presents an interpretation of the European crisis based on the balance of payments imbalances within the Eurozone and highlighting the role of the “internal” real exchange rates as a primary cause of the crisis. It explores the structural contradictions that turn the Euro into a “foreign currency” for each individual Eurozone country. These contradictions imply the inability of national central banks to monetize the public and private debts, which makes the Euro crisis a sovereign crisis similar to those typical of emerging countries, but whose solution presents additional obstacles.

Stabilization, volatility and the equilibrium real exchange rate

In a general equilibrium model. we show that the value of the equilibrium real exchange rate is affected by its own volatility. Risk averse exporters. that make their exporting decision before observing the realization of the real exchange rate. choose to export less the more volatile is the real exchange rate. Therefore the trude balance and the variance of the real exchange rate are negatively related. An increase in the volatility of the real exchange rate for instance deteriorates the trade balance and to restore equilibrium a real exchange rate depreciation has to take place. In the empirical part of the paper we use the traditional (unconditional) standard deviation of RER changes as our measure of RER volatility.We describe the behavior of the RER volatility for Brazil,Argentina and Mexico.Monthly data for the three countries are used. and also daily data for Bruzil. Interesting patterns of volatility could be associated to the nature of the several stabilization plans adopted in those countries and to changes in the exchange rate regimes .

Especulative (sic) attack on exchange rate target zone regime : the uncertainty case

We present a continuous time target zone model of speculative attacks. Contrary to most of the literature that considers the certainty case, i.e., agents know for sure the Central Bank behavior in the future, we build uncertainty into the madel in two different ways. First, we consider the case in whicb the leveI of reserves at which the central bank lets the regime collapse is uncertain. Alternatively, we ana1ize the case in which, with some probability, the government may cbange its policy reducing the initially positive trend in domestic credito In both cases, contrary to the case of a fixed exchange rate regime, speculators face a cost of launching a tentative attack that may not succeed. Such cost induces a delay and may even prevent its occurrence. At the time of the tentative attack, the exchange rate moves either discretely up, if the attack succeeds, or down, if it fails. The remlts are consistent with the fact that, typically, an attack involves substantial profits and losses for the speculators. In particular, if agents believed that the government will control fiscal imbalances in the future, or alternatively, if they believe the trend in domestic credit to be temporary, the attack is postponed even in the presence of a signal of an imminent collapse. Finally, we aIso show that the timing of a speculative attack increases with the width of the target zone.

Optimal exchange rate policy, optimal incomplete taxation and business cycles

Implementation and collapse of exchange rate pegging schemes are recur- rent events. A currency crisis (pegging) is usually followed by an economic downturn (boom). This essay explains why a benevolent government should pursue Þscal and monetary policies that lead to those recurrent currency crises and subsequent periods of pegging. It is shown that the optimal policy induces a competitive equilibrium that displays a boom in periods of below average de- valuation and a recession in periods of above average devaluation. A currency crisis (pegging) can be understood as an optimal policy answer to a recession (boom).

The effects of gender segregation at the establishment level: an empirical analysis using a panel of matched employer-employee data

This paper studies the relationship between segregation of women across establish- ments and the wages of males and females. To investigate this issue empirically we use a panel of matched employer-employee data from Brazil. Various longitudinal models are used to assess the wage impact of establishment gender segregation. Overall, the results indicate that the e ect of establishment female proportion on the wages of males and females is negative. We also compare these longitudinal results with cross-section estimates, which are the usual ones obtained in the related literature. This com- parison suggests that unmeasured, time-invariant worker- and establishment-speci c e ects are correlated with the establishment female composition.

The effects of government deficit on equilibrium real exchange rates and stock prices

This paper studies the effect of government deficits on equilibrium real exchange rates and stock prices. The theoretical part modifies a two-country cash-in-advance model like used in Lucas(1982) and Sargent(1987) in order to accommodate an exchange rate market and a government that pursues fiscal and monetary policy targets. The implied result is that unanticipated shocks in government deficits raise expectations of both taxes and inflation and, therefore, are associated with real exchange rate devaluations and lower stock prices. This finding is strongly supported by empirical evidence for a group of 19 countries, representing 76% of world production
