Este trabalho buscou verificar a existência de hysteresis nas exportações brasileiras de produtos manufaturados. Para isso, foi realizada inicialmente uma análise descritiva das empresas industriais exportadoras e a estimação de uma árvore de classificação para o período de 1989 a 1997. Essa primeira análise demonstrou que existe uma assimetria entre o número de empresas entrantes no período favorável às exportações e o número de empresas desistentes no período não favorável, dando evidências da permanência/persistência das empresas exportadoras no período de 1989-1997. Além disso, constatou-se a tendência à inação (?wait and see?) das empresas no mercado externo para período de 1990-1993 e uma indução à saída de empresas para o período de 1994-1997. Em seguida, a partir de dados agregados para o período de 1985 a 2003, foi realizada uma análise de séries temporais. Os resultados dessa análise evidenciaram a hipótese de existência de hysteresis para alguns setores selecionados, tanto no longo prazo como para o curto prazo. / This work had as main objective to verify the existence of hysteresis in the Brazilian exportations of manufactured products. For this objective, a descriptive analysis of exporting industrial firms was initially carried through and the estimate of a tree of classification for the period of 1989 - 1997. These first analyses had demonstrated that existence of an asymmetry between the number of incoming firms in the period favorable to the exportations and the number of desisting firms in the not favorable period, giving evidences of the permanence/persistence of the exporting firms in the period of 1989-1997. Moreover, one evidenced an trend of \"wait and see\" of the firms in the export market for the period of 1990-1993 and induction to the exit of firms for the period of 1994-1997. After that, from aggregated data for the period of 1985 - 2003, a time serial analysis was carried through. These results had been corroborated that evidenced the of hysteresis hypothesis for some selected sectors, as much in the long-run as for short-run.

L’objectif de cette thèse est d’analyser les liens entre le taux de change réel, l’inégalité des revenus et la pauvreté rurale en Chine. Nous visons à répondre à deux principales questions, à savoir : (i) dans quelle mesure la variation du taux de change réel a-T-Elle influencé l’inégalité des revenus en Chine? (ii) la variation du taux de change réel contribue-T-Elle à expliquer l’évolution de la pauvreté rurale chinoise? Pour ce faire, la thèse s’organise autour de quatre chapitres. Le premier chapitre présente une vue d’ensemble de l’évolution du système de change chinois, en tenant compte de la situation internationale en pleine mutation et des conditions économiques, politiques et institutionnelles de ce pays durant ses différentes phases du développement. Le chapitre 2 décrit l’évolution de l’inégalité des revenus et de la pauvreté rurale en Chine. On constate que depuis 1978 la Chine a connu des progrès remarquables dans la réduction de la pauvreté mais cette réduction s’est accompagnée par un accroissement des inégalités. Par ailleurs, il s’avère qu’en Chine, la variation du taux de change réel joue un rôle important dans l’évolution de l’inégalité des revenus et de la pauvreté rurale. Le chapitre 3 fournit une analyse théorique sur les liens entre le taux de change réel et la répartition des revenus. Il a été mis en évidence que ces liens sont complexes, impliquant un grand nombre de canaux de transmission (directs et indirects). Enfin, le chapitre 4 est consacré à l’estimation économétrique des liens entre le taux de change réel, l’inégalité des revenus et la pauvreté rurale en Chine à l’aide de données de panel au niveau des provinces chinoises. Les résultats de nos estimations économétriques montrent que l’appréciation réelle de la monnaie chinoise contribue à réduire l’inégalité des revenus et la pauvreté rurale en Chine au cours de la période des réformes. / The present dissertation investigates the relationship between real exchange rate, income inequality and rural poverty in China. We attempt to answer two principal questions: (i) to what extent will the variation of real exchange rate affect income inequality in China? (ii) how will the variation of real exchange rate impact the evolving pattern of China’s rural poverty? For this purpose, the present dissertation is organized into four chapters. Chapter One reviews the evolution of China’s exchange rate regime, by taking into consideration the fast-Changing international situations as well as the internal economic, political and institutional conditions of this country. Chapter Two describes the changing pattern of income inequality and the evolution of rural poverty in China. It is observed that since 1978 China has achieved remarkable progress in the alleviation of poverty, which has been accompanied, however, by rising inequalities. In addition, there is growing evidence that the variation of real exchange rate plays an important role in affecting China’s distribution of income. Chapter Three provides a theoretical analysis on the linkage between real exchange rate and income distribution. Such an linkage has been shown to be complex, involving various transmission channels (direct and indirect). Finally, with the help of panel data at provincial level, Chapter Four empirically estimates the nexus between real exchange rate, income inequality and rural poverty in China. The econometric results show that the real appreciation of the Chinese currency significantly contributes to the reduction of income inequality and the alleviation of rural poverty in post-Reform China

The RMB exchange rate started to be a widely international issue discussed with Sino-U.S. relations of Economic since 2002.The main Objective of this study is finding the causes of undervaluing and pressures of facing. However, China¡¦s Financial Security is closely related to the process participating in the international system of finance, so this article is concentrated in the scope of correlate research of RMB exchange rate, and analyzed to find what pressures China facing and what policies China choosing. The causes which nominal exchange rate was biased against the real exchange rate are discriminated between labor factor and interest factor, with observing the change of balance of payment and foreign exchange reserves, so the foreign market unequilibrium can be explained further by analyzing the flow and capital. Finally, the strategic consider of U.S. is also the one of factors that influences RMB exchange rate despite of the economic risks in China. perspectives of international politics in Pressuring RMB exchange rate or opening markets are considered on the coordination of interest groups¡Bcongress and government of United States. The conclusion revealed the main reason that China is now facing major secure threats, there are looseness in capital controls, and rigidity in foreign exchange regimes. This threats result in failing to diversify its investment risk of foreign exchange and causing its monetary policy much pressure. The other hand, The purposes of putting pressure on RMB exchange rate by U.S. reflected that they not only transferred the responsibility of unemployment and deficit but also showed the need of domestic politics and the consideration of international politics, so the strength of pressure was not the same in the time series. Therefore, the study argues that the dispute of Sino-U.S. exchange rate was not only the outcome of interaction between two countries¡¦ trade but also this regime of China and purpose of U.S. should be discussed and observed continually.

With financial liberalization and economic globalization, international trade and capital transactions result in larger exchange rate fluctuations than in the past. Besides, it can¡¦t be ignored that the change of exchange rate influences the economics and real exchange rate which be regarded as the indicator of external competitiveness becomes more important than before, so my paper aims to know not only whether there is stochastic segmented trend in their fluctuation but also the factors which are closely related to regime switches. As we all know that it is significant to forecast the volatility of exchange rate in the global society. A number of previous studies discussed the relationship between exchange rate and fundamentals under the monetary models, however many people found that these models are handicapped in out-of sample forecasting. Therefore, I compare the forecasting performance of the real interest differential monetary (RID) model of Frankel (1979) with the models which I built in the paper. By using the market share of the top ten currencies in 2010 which is published by Bank for International Settlements (BIS) and the fundamentals. The empirical results indicate that fundamentals do not only matter for real exchange rate, but are also related to the switches between the regimes. Besides, the real exchange rates are highly persistent in each regime and the effect of fundamentals is different in different countries. At last, my result suggest that the models which I built in the paper provide better forecast in the yen, pound sterling and New Zealand dollar than the RID model.

The subject of this study is to examine the determinants of the real exchange rate in Taiwan. The sample period is from the first quarter of 1982 to the second quarter of 2011, and the variables include the real exchange rate, terms of trade, productivity differential, the real oil price, reserve differential, real interest rate differential, and the net foreign assets of Taiwan and America. The empirical results show that there is no cointegration between the real exchange rate and independent variables. Using a VAR model, this study finds that although the central bank of Taiwan would intervenes the real exchange rate, the variable related to the economic growth is still significant. At 5% significance level, an increase in the productivity differential leads the real exchange rate to depreciate. In addition, from the result of the granger causality test, this study finds that there exists unidirectional causality from the productivity differential and central bank intervention respectively to the real exchange rate. The effect of central bank intervention on the real exchange rate only persists one period, and the effect of the productivity differential persists two more periods. Therefore, it can be concluded that when estimating the future real exchange rate, it may be useful to take the productivity differential into account.

The main purpose of this thesis is to explore whether the Balassa-Samuelson hypothesis can effectively explain the long-term change of the real exchange. The recent panel unit root, panel cointegration tests and fully modified OLS are applied to examine the four tested equations that are based on the Balassa-Samuelson hypothesis. 1. Relative differential productivity between traded and non-traded sectors influences price differential in two sectors. 2. We extend the relative productivity in non-traded and traded sectors causing change in non-traded relative price into the two-country model. 3. The appreciation (depreciation) of the real exchange results from the different relative price of the two-country model. 4. The appreciation (depreciation) of the real exchange is caused by the different relative productivity of the two-country model. The data span is from 1971 to 1995, and includes 12 OECD countries. There are three main different points from the existing literatures. 1. We apply some newly developed panel unit root tests to estimate the equations based on Balassa-Samuelson hypothesis. 2. The previous documents only estimated the model of one variable, but the estimation of two variables was rare. In the equation 14 and 15, we examined the two variables in both. 3. In the calculation of the price, owing to the difficulties of collecting data from various sectors, we use a special way to measure the price. Finally, we can observe from the results of the empirical study: when productivity of the domestic sectors differentiates, that is, 1% increase in relative productivity between traded and non-trade sectors causes 0.53% increase in domestic relative prices. When it is taken into the two-country model, the increase of productivity will cause the appreciation of the real exchange rate. This can explain why in the developed countries like the U.S. and Japan, the faster increase in domestic relative productivity causes the appreciation of real exchange rates in the long run.

The main purpose of this thesis is to explore whether the Balassa-Samuelson hypothesis can effectively explain the long-term change of the real exchange. The recent panel unit root, panel cointegration tests and fully modified OLS are applied to examine the four tested equations that are based on the Balassa-Samuelson hypothesis. The data span is from 1985 to 2002, and includes 7 east asian countries. 1. Relative differential productivity between traded and non-traded sectors influences price differential in two sectors. 2. We extend the relative productivity in non-traded and traded sectors causing change in non-traded relative price into the two-country model. 3. The appreciation (depreciation) of the real exchange results from the different relative price of the two-country model. 4. The appreciation (depreciation) of the real exchange is caused by the different relative productivity of the two-country model. Finally, we can observe from the results of the empirical study: when productivity of the domestic sectors differentiates, that is, 1% increase in relative productivity between traded and non-trade sectors causes 0.28% increase in domestic relative prices. When it is taken into the two-country model, the increase of productivity will cause the appreciation of the real exchange rate.

This thesis is composed by three Chapters. In the first Chapter, we present the main stylized facts about the behavior of retail prices in Brazil using micro data from the CPI index computed by the Fundação Getulio Vargas. Moreover we construct time series of price-setting statistics and relate them to macroeconomic variables using regression analyses. In Chapter 2, we investigated the relevance of heterogeneity in countries price stickiness on good-level real exchange rate persistence, considering a newly constructed panel data set of relative prices of 115 common products between the U.S. and Brazil. Chapter 3 is devoted to the relation between sectoral price stickiness and inflation persistence. / O objetivo desta tese é investigar as estratégias de precificação no Brasil, enfatizando os efeitos sobre a persistência da inflação e da taxa de câmbio real setorial. Esta tese é composta por três capítulos. No primeiro capítulo, nós apresentamos as principais características do comportamento dos preços no Brasil, utilizando os microdados do Índice de Preços ao Consumidor, computado pela Fundação Getúlio Vargas. Adicionalmente, nós construímos as séries de tempo das estatísticas de price-setting e as relacionamos com as variáveis macroeconômicas utilizando análise de regressão. No capítulo 2, nós investigamos o efeito da heterogeneidade da rigidez de preços entre países sobre a persistência da taxa de câmbio real setorial, considerando um painel de preços relativos de 115 produtos comuns entre Brasil e EUA. Por fim, o capítulo 3 explora a relação entre rigidez de preço setorial e persistência inflacionária.
