In this companion paper to Broll and Mukherjee (2017), we empirically analyse how exchange rate volatilities affect firms optimal production and exporting decisions. The firms elasticity of risk aversion determines the direction of the impact of exchange rate risk on exports. Based on a flexible utility function that incorporates all possible risk preferences, a unique structurally estimable equation is used to estimate the risk aversion elasticities for a panel of Indian service sector (non-financial) firms over 2004-2015, using the quantile regression method.

The theory of optimum currency areas states that the more two countries trade with each other, the better candidates they are for a currency union. In terms of the endogeneity argument, convergence follows from joining a currency union and the integration process itself turns the countries into optimal currency areas. The potential increase in trade is regarded as one of the most important benefits of a currency union. Indirect evidence from studies on the effect of exchange rate volatility on trade does not support this claim. Rose argues that the common currency effect on trade is separate from the effect of the elimination of exchange rate variability and finds a large positive effect of a currency union on trade. Although his methodology has met with criticism, most studies find a positive estimate. A meta-analysis of the studies confirms that a common currency has a statistically and economically significant trade-creating effect. / Economics / M.Com. (Economics)

The objective of this thesis is to examine real exchange rate volatility, with a particular focus on investigating the causes of exchange rate jumps. While the predominant approach in the literature is to examine the interaction between nominal rigidities and nominal shocks, this thesis examines the volatility that arises from real rigidities and shocks. Trying to better understand the transmission of real shocks to the exchange rate is a worthwhile task, given the substantial evidence that these shocks and rigidities are important for explaining other economic fluctuations. This thesis develops theoretical models that examine the contributions of specific real rigidities to exchange rate volatility. Chapter 1 introduces our baseline specification - a frictionless model, with the exception of capital adjustment costs. This baseline generates very mild exchange rate fluctuations. Additional rigidities are required to generate volatility of the magnitude that is typically observed. Chapter 2 finds that introducing imperfect asset substitutability - specifically, home asset bias - goes a little towards achieving this. When investors are biased, the exchange rate must adjust by more to equilibrate asset markets. This greater burden of adjustment on the exchange rate along the short run path typically translates to larger jumps after shocks. Similarly, Chapter 3 shows that augmenting the baseline with banks and financial frictions raises exchange rate volatility. The key point is that, in the presence of financial frictions, there is a risk premium that widens after negative shocks, increasing the required adjustment of the exchange rate. A fourth chapter extends Chapter 3 and shows that unconventional credit policy, while beneficial in some respects, nonetheless entails nontrivial costs because it invites moral hazard by encouraging banks to be more highly leveraged, which increases exchange rate and consumption volatility. So, the overall message is that, in the presence of plausible real frictions - including (i) capital adjustment costs, (ii) imperfect asset substitutability, and (iii) financial frictions - real shocks can generate a plausibly significant degree of real exchange rate volatility. This thus posits an additional explanation of exchange rate jumps that complements the predominantly monetary literature.

本文探討匯率不確定性與台灣對中國大陸出口之關係，模型中參考Cushman (1986) 觀點加入第三國變數之效果。研究期間以1997年至2010年之季資料，同時考慮總合資料以及部門別資料，並以GARCH估計實質匯率波動性。第三國則利用出口近似度的計算選擇了前四大競爭國，分別為南韓，日本，馬來西亞及新加坡。此外，部門則以HS二碼分類選擇出口至中國大陸前四大之部門，包括機械與電子、精密儀器、橡膠與塑膠類產品及化學品。 本文檢定變數是否有單根。若有單根則進一步檢定這些變數是否存在共整合關係。在確定存在共整合關係後，利用完全修正最小平方法及誤差修正模型進行估計。本文實證結果顯示：匯率不確定性對出口量有負向之影響關係。就部門而言，本文探討的四個部門之結果也反映匯率不確定性對出口具有負向影響，但是以電子產品及塑膠橡膠類之影響最為顯著。 / This paper investigates the relationship between exchange rate volatility and Taiwan’s exports to Mainland China. In the empirical model, the third country effects suggested by Cushman (1986) are considered. GARCH model is employed to estimate real exchange rate volatility. Both aggregate and sectoral quarterly data covering 1997 to 2010 are used in our sample. The third countries are determined by export similarity. The top 4 countries with the highest degree of export similarity are chosen, including South Korea, Japan, Malaysia and Singapore. In addition, the top 4 Taiwan’s exporting sectors are examined respectively, including machinery and electronic equipment, precision equipment, rubber and plastics, chemicals industries. We first test for unit root of the variables used in the study, and then check the existence of co-integration between the variables with unit root. After confirming the existence of co-integration relationship, we use FMOLS (Fully Modified OLS) and VECM (Vector Error Correction Model) to estimate the coefficients. Our empirical results suggest that there is a significantly negative effect of exchange rate volatility on Taiwan’s total exports. They also indicate that there is a negative relationship between exchange rate volatility and Taiwan’s sectoral exports. Among the top 4 exporting sectors, exchange rate volatility tends to have higher impacts on the machinery and electronic industry as well as chemical industry.

This master's thesis investigates the impact of exchange rate volatility on trade balance of the Czech Republic during 2005-2016. The analysis is performed on the constructed panel dataset for 53 trading partners of the Czech Republic by estimating the trade gravity models. The realized volatility values are obtained for 43 Czech koruna pairs against the local currencies. The variables included into the empirical analysis are the GDP and population of the Czech Republic and its trading partners, realized volatility, weighted distance, contiguity, direct access to the sea and information on EU and OECD membership. The methodological approaches in the analysis are calculations of realized exchange rate volatility and for gravity models panel data estimation techniques: pooled OLS, fixed effects and random effects. The gravity models are compared by the formal tests, and the most efficient among them is the fixed effects. The results of the estimated augmented model reveal significant positive impact of exchange rate volatility on trade balance of the Czech Republic. The key variables that have the expected significant positive impact on trade balance are GDP of the Czech Republic and its trading partners in the basic model, population of the Czech Republic and EU membership in the augmented model....

本文目的在於探討匯率不確定性對台灣出口波動之影響。本文應用Barkoulas et al.(2002)理論架構，利用台灣1989年至2007年的月資料。實證結果發現：美元、日圓兌新台幣的匯率波動對於台灣出口美、日兩國的數量並無明顯的影響。美元兌新台幣的匯率波動對於以美國為進口國的台灣出口波動則有正向的影響；日圓兌新台幣的匯率波動對於以日本為進口國的台灣出口波動卻沒有顯著影響。本文認為：造成美元匯率波動主要支配力量，來自於貨幣政策制定者掌握之資訊優勢差異；造成日圓匯率波動的來源則無主要支配力量的存在。造成此種結果的原因在於貨幣政策制定者長久以來所建立的政策可信度所致，削減了造成美元匯率波動的另外二股力量。因此，新台幣兌換美元匯率波動取決於貨幣政策制定者掌握經濟真實狀況的能力與其貨幣政策方向。 / This paper investigates into the effect of exchange rate uncertainty on Taiwan export volatility. Under the theoretical framework of Barkoulas et al.(2002) and the empirical monthly data of Taiwan exports from 1989 to 2007, it is summarized that the exchange rate volatility of NTD/USD and NTD/JPY had no effect on the Taiwan exporting volume toward U.S. or Japan. However, the exchange rate volatility of NTD/USD did have positive effect on the export volatility of Taiwan to U.S. while that of NTD/JPY had no significant effect on the export volatility of Taiwan to Japan.It is argued that the dominant source of NTD/USD exchange rate volatility resulted from the variance of monetary authorities’ information advantage. On the other hand, it exists no such a dominant source in NTD/JPY exchange rate volatility.

本文主要是研究浮動匯率期間匯率波動對出口產業的影響。一般認為，匯率波動匯會使出口廠商的利潤風險增加，所以波動對於出口量的影響是為負的效果。不過，由於許多國外的研究的結果並不一定支持這種看法。本文針對台灣1984到1995年的資料進行實證研究，並且分別就不同出口產業對匯率波動的反應程度做討論，包括紡織類，塑膠化學類，電子類，機械類及基本金屬類五種產業，主要分為兩個架構分析： 　　（一）衡量匯率波動因子：對於匯率波動的衡量分成兩種方法：一種是以過去匯率變動的方式來衡量，另一種是以本期匯率預測的誤差來衡量，大部份的文獻都是採用前者。在此，為了將廠商事先避險的行為引入，所以採用後者的方法，將預測到的波動與未預測到的波動分離開來。 　　（二）匯率波動對各產業出口量的影響：將所有符合I(1)性質的變數用Johansen的方法做長期共整合關析的估計，再利用Granger Representation Theorem導出短期誤差修正模型，並將符合I(0)性質的波動因子引入模型當中，以便觀察匯率波動對出口量的影響。結果發現，各產業的出口量皆與匯率波動間存在明顯的負相關，其中以電子產業的影響最顯著，紡織類次之，基本金屬類影響最小，根據產品的特性分析可發現：當出口競爭愈激烈者，或是出口彈性愈大者，相對來講，會對匯率波動的反應較敏感。

How should central banks react to movements in the exchange rate? Can social welfare be improved if the policy maker is giving explicit or implicit consideration to fluctuations in the exchange rate? These are some of the principal questions addressed in this thesis, which analyzes the influence of exchange rates on prices and monetary policy, from an empirical as well as a theoretical perspective. The thesis consists of four self-contained papers, and sets off by providing some empirical evidence for incomplete exchange rate pass-through. Incomplete exchange rate pass-through is subsequently incorporated into a theoretical model of a small open economy, to study how exchange rate fluctuations affect monetary policy. The first chapter is an empirical paper studying the relation between exchange rates and prices, using data on Swedish exports of automobiles and kraft paper. A price determining error correction model indicates results consistent with price discrimination and incomplete exchange rate pass-through. In the second chapter, a small open economy aggregate supply-aggregate demand model, allowing for incomplete exchange rate pass-through, is developed to analyze the effects of limited pass-through on monetary policy. The results suggest that the optimal policy reaction, both to foreign and domestic shocks, is dependent on the degree of exchange rate pass-through. The third chapter studies what the delegated monetary policy should be in an open economy with limited pass-through. In particular, the question of whether to delegate an exchange rate-stabilization objective to the policy maker is investigated. The results show that incorporation of an explicit nominal, or real, exchange-rate term in the (optimized) objective function only improves social welfare marginally. The fourth chapter assumes, in contrast, that monetary policy is implemented through a simple instrument rule. It is examined whether the policy maker’s performance, in terms of social welfare, can be improved by also responding to the exchange rate. The results indicate that the exchange rate-augmented policy rules do not outperform an optimized rule without the exchange rate, irrespective of the degree of pass-through. Social welfare is, however, improved by an indirect exchange rate response, which is reached using a policy rule based on Consumer Price Index (CPI) inflation, rather than on domestic inflation. / Diss.

La présente thèse tente de savoir s’il est opportun pour les pays en développement les moins avancés de s’engager davantage dans le processus de globalisation financière pour promouvoir leur croissance, et si ce processus influence les effets des instabilités, financière et monétaire, sur cette dernière. A cette fin, la thèse se déroule en trois parties. Avant d’examiner le cadre théorique de la globalisation financière, la première partie esquisse sa genèse avec en arrière-fond la recherche d’une réponse au problème de sa régulation. La deuxième partie s’intéresse à la littérature sur les effets de la globalisation financière sur la croissance, afin d’en tirer les enseignements pour une étude de 72 pays en développement à revenu bas de 1972 à 2011. La troisième partie se focalise sur les impacts de la globalisation financière et des deux instabilités considérées isolément, puis en interaction avec la globalisation sur la croissance à travers deux études empiriques basées sur le même cadre spatio-temporel que l’étude précédente. Ces dernières sont précédées par une revue des relations entre la globalisation financière, l’instabilité financière puis monétaire et la croissance, avec une analyse théorique de l’instabilité financière. Il en ressort que les instabilités, financière et monétaire, ont des effets négatifs sur la croissance, tandis que la globalisation financière, et en particulier la globalisation par l’investissement contrairement à celle par l’endettement, promeut les bienfaits des politiques économiques et du commerce extérieur, en plus de son effet positif direct sur la croissance même en présence des deux instabilités dont elle diminue les effets négatifs. / This thesis examines whether or not it is beneficial for least developed countries to engage more in the process of financial globalization in pursuit of their economic growth, and if this process influences the effects of financial and monetary instability on the latter. This thesis is divided into three parts. Before examining the theoretical framework of financial globalization, the first part sketches its genesis on a background of the research for an answer to the problem of its regulation. The second part focuses on the literature on the impact of financial globalization on growth. This is done in order to draw lessons for the establishment of a study covering 72 low-income developing countries over the period 1972-2011. The third part centers on the impact on economic growth of financial globalization and the two aforementioned types of instability, discussed both separately and in conjunction. Evidence is provided by two empirical studies based on the same spatio-temporal framework as the previous one. These studies are preceded by a review of the literature on the relationship between financial globalization, financial and then monetary instability and growth, in addition to a theoretical analysis of financial instability. This illustrates that financial and monetary instability have negative effects on growth, while financial globalization and in particular investment-globalization, unlike indebtedness-globalization, promotes the benefits of macroeconomic policies and international trade. This can be find in addition to its direct positive effect on growth, even in the presence of the two instabilities of which it reduces the negative effects.
