The Analysis of Current Account Fluctuations of Taiwan ¢w the Case of Short-run and Long-run PerspectivesPan, Shang-yi 26 July 2005 (has links)
The fluctuation of the world economy has a tremendous influence to domestic imports and exports to a small opened economy. In another word, it has great impact to the current account of a small opened economy. After the 1980s, Taiwan relies on the growth of net export to drive its economy growth, showing that depend on to foreign trade degree quite high, so government values the current account very much. With the economic variables of the region of America, Asia, and Europe to carry on regional study the relation with the current account of Taiwan, the relevant parameter included in this research is that foreign production value, domestic production value, real effective of exchange rate, and real interest rate differential of domestic and international. Utilize structural vector autoregressive model, with impulse response functions and forecast error variance decompositions analysis result, to consider each variable in short-run and long-run to the current account of influence.
According to impulse response functions, it synthesizes three regional analysis results, the current account accord with the theories with the relevant parameter. The foreign production value increases to cause the current account increment. The domestic production value increases to cause the current account reduced and converge in the long-run. The real effective of exchange rate increases to cause the current account surplus in the short-run, the impulsive effect is convergence in the long-run. The real interest rate differential increases to cause the current account deficit in the short-run.
According to forecast error variance decompositions, the current account is influence by the real effective of exchange rate and itself factor in three regions, in addition the influence by the foreign production value in the region of America and Asia. In the region of America and Asia, the current account receives self influence that decreases progressively at time changes that part substitutes by the foreign production value. Under the long-run, the foreign production value in the region of America and Asia is also influence by the current account because imports and exports of Taiwan are in the majority that the main country comes from America and Asia, that the production value of regions are easier to cause the current account. The current account always causes by the real effective of exchange rate in the long-run. Accord with Shirvani and Wilbratte (1997), the real exchange rate has the long-run relational with the current account in real example analysis. In the short-run, the exchange rate depreciation has not influenced the result to the current account. In the long-run, the depreciation can improve the current account to become surplus.
This research discovers to influence the factor of the current account of Taiwan, in the region of America and Asia, the foreign production value makes the phenomenon with the current account surplus in the long-run. In the region of American, Asia, and Europe, the real effective of exchange rate increases to make the phenomenon with the current account surplus in the long-run, the current account receives self influence no matter under short-run and long-run. In the short-run, the influence of the current account results negative direction and oscillation to convergence.

Role sentimentu podniků v transmisi měnové politiky: zjištění pro eurozónu / The Role of Business Confidence in the Monetary Policy Transmission Mechanism: Evidence from the Euro AreaLiu, Zhaozhi January 2021 (has links)
Traditional macroeconomics believes that confidence is not the main cause of economic fluctuations, but when faced with financial crises, monetary authorities still emphasize the role of stabilizing confidence. Although people generally agree that confidence is an important part of the transmission of macro-policies to micro- individuals, there is neither empirical evidence support nor corresponding mechanism research. This thesis attempts to answer the following questions: Does business confidence affect the effectiveness of monetary policy? Does business confidence have the same impact on monetary policy in different economic periods? This thesis first constructed a structural vector auto-regression (SVAR) model to test the role of business confidence in the transmission of monetary policy in the euro area. The empirical results show that expansionary monetary policy can effectively boost business confidence while stimulating output growth. In addition, this thesis extends the model by introducing share prices and exchange rates to investigate the role of these two important to the monetary transmission mechanism, concluding that business confidence plays a strong role in interest rate transmission and a weaker role in the transmission of asset prices and exchange rates. Subsequently, in order to...

Trade linkages and growth in South Africa: an SVAR analysisLiu, Xinman 17 March 2020 (has links)
This paper investigates the vulnerability of South Africa to the shocks that originate from its major trading partners over time using a structural vector autoregressive framework. We examine the impact of shocks emanating from the EU, the US, China, Japan, India and Brazil on South Africa’s output growth through both direct and indirect trade linkages, by considering the changing trade patterns from 1996 to 2017. The results suggest that the South African economy has become more integrated with emerging economies. Furthermore, China has increased its impact on the output growth of the other sample economies through trade linkages, which implies that developments in China are of increasing importance to other economies. The US and the EU are still dominated in propagating shocks despite their declining impact on the output growth of other economies in this sample.

The Impacts of Margin Trading on Rate of Return and Volatility in the Stock Market: A Study using the SVAR Model and Panel RegressionsJanuary 2018 (has links)
abstract: Although margin trading has significant impacts on the stock market, extant research has mainly focused on its effect on stock price volatility and has rarely examined its influence on the rate of returns. In addition, little systematic research has examined the differential effects of margin trading under different circumstances. This thesis examines the effects of margin trading in bull market, bear market, balanced market and among stocks included in main board, SMEs(small and medium-sized enterprises) board, GEM(growth enterprises board), as well as large-cap and small-cap in China. I further studied the long-, medium-, and short-term influences of margin trading on the volatility of stock price, return rate, and liquidity of the market by both using the SVAR model and conducting panel data analyses.
The findings show that: a)Volatility. Margin trading can effectively curtail the medium- and short-term volatility of the share price under any market condition but has no prominent influence on long-term volatility. b)Profitability. Margin trading enhances profitability in the bull market with an apparent leverage effect while having no significant effects on short-term profitability in the balanced market and the bear market. c) Individual shares with different attributes. The influences of margin trading on the large-cap and small-cap shares, shares with high vs. low PE ratio, shares included in the main board and SMEs stocks vary in different types of market. d) Liquidity. The influences of margin trading on the fluidity of market are significantly different in the bull, bear, and balanced markets.
Finally, I set up a new trading strategy based on the above conclusions. The result from hypothetical trading demonstrates that the newly-created trading strategy works better than the long-term holding strategy, highlighting the practical implications of this thesis in addition to its implications for research / Dissertation/Thesis / Doctoral Dissertation Business Administration 2018

What role does uncertainty play in the housing markets of selected European Countries?Enges, Emil, Torehov, Hampus January 2022 (has links)
In this study, we investigate the relationship between national and global uncertainty with house prices. Uncertainty is measured with the economic policy uncertainty index developed by Baker et al. (2016). The relationship is evaluated with eight SVAR-models that are Cholesky decomposed to restrict the contemporaneous relationship between variables, this is used to model the housing market. We create two models for each country, one that includes the local uncertainty and one that includes global uncertainty. The studied countries are two larger and two smaller economies in the EU, namely Sweden, Denmark, Germany, and France. We investigate the impulse response functions to establish the short-run dynamics and then compare them amongst each other. The results show that uncertainty has a negative effect on house prices and that global uncertainty hasa larger impact than local uncertainty, except for Sweden´s case. Germany is most resilient to the effect of uncertainty among the studied countries. This can be because of the size of the rental housing market in Germany. Interestingly we also find that in all cases except for Denmark our models don’t find a consistent relationship between short-term interest and housing prices in the short run, which can be an indication of a bubble. Further studies are required to investigate how different housing policies affect the volatility of the housing market that is created by uncertainty.

Conception, construction et évaluation d'un indice sous-jacente pour l'économie vietnamienne / Concept, structure and evaluation of core inflation index for the Vietnam economyPham, Thi Thanh Xuan 14 April 2015 (has links)
Cette thèse est pour le but final d’estimer avec succès un indice d’inflation sous-jacente donnant les meilleures prévisions de l’inflation au Vietnam. D’un point de vue méthodologie, cette thèse s’appuie sur les démarches qualitatives afin de mesurer un indice d’inflation sous-jacente pour l’économie vietnamienne. Les différentes méthodes pour mesurer l’inflation sous-jacente ont été utilisées. La structure de cette thèse est établie en accord étroitement avec nos objectifs de recherche. L’introduction générale présente un aperçu général du sujet de recherche. Le chapitre 1 est à l’appui sur l’explication de la nature de l’inflation sous-jacente. Les chapitres 2 et 3 portent sur les mesures de l’inflation sous-jacente et les applications dans le cas du Vietnam. Les mesures statistiques – qui sont familière dans les banques centrales à travers le monde – sont reportées dans le chapitre 2. Le chapitre 3 présente les modèles économétriques qui aident à estimer l’inflation sous-jacente (le modèle SVAR de Quad-Vahey, le modèle à tendances communes et le modèle à composantes inobservables). Chaque mesure est également étudiée et reportée dans le processus suivant : d’abord, la notion d’inflation sous-jacente ; puis, la littérature de base de cette notion d’inflation sous-jacente ; ensuite, les techniques d’estimation de l’inflation sous-jacente et enfin, l’application de cette mesure dans le cas du Vietnam. Les indices d’inflation sous-jacente obtenus aux chapitres 2 et 3 sont examinés, analysés et comparés les uns aux autres. Les tests sont reportés dans le chapitre 4. La conclusion générale résume les résultats finaux de ce travail de recherche.Le résultat officiel de ce travail est un ensemble de dix indices d’inflation sous-jacente qui satisfont à toutes les propriétés attendues et qui semblent optimaux pour la prévision d’inflation. Un autre résultat qui va au-delà de nos attentes, est que parmi ces dix indices, l’un d’entre eux possède un double fonction, à savoir un indice prédictif de l’inflation et un indice de référence de l’inflation. Cet indice possède un pouvoir prédictif élevé et semble pouvoir être largement accepté par le grand publie comme leur indice de référence. Un autre apport supplémentaire de cette thèse est les remarques concernant la technique d’estimation de l’inflation sous-jacente appropriée dans le cas du Vietnam. / This thesis focuses on concepts, structures and evaluation of core inflation index for the Vietnam economy. The final purpose of the research is to estimate the core inflation index which enable to provide the best prediction of the Vietnam inflation. From the point of view of methodology, the thesis highlights on the qualitative approaches in order to measure the core inflation index for the Vietnam economy. The different methods have been used as follows: First, the pure statistical measurements such as trimmed mean, exclusion, median, weighted median and reduced - weighted average... and a more sophisticated method, i.e. the dynamic factor model. This model helps to capture the dynamic of an underlying factor which generates the tendency of inflation. Secondly, the three econometric models include SVAR model developed by Quah-Vahey, common trend model and unobservable components model. These models facilitate to better integrate the macroeconomic theory into measurement of core inflation. The later model is selected to overcome the disadvantages of the former one.The structure of the thesis is established in accordance with our research objectives. The introduction presents a brief overview of the research subject. The first chapter discusses the core inflation nature. The chapters 2 and 3 analyze the core inflation measurements and their applications in the case of Vietnam. The statistic measures that are more familiar with central banks in the world are presented in the chapter 2. The third one presents in details the three econometric models. Each measure is studied and presented in the following process: (i) the notion of core inflation, (ii) its theorical background (iii) the estimation techniques and (iv) the application of these measures into the Vietnam data.The obtained core inflation indexes are examined, analyzed and compared to each other. Its results are reported in the chapter 4. The general conclusion sums up the final results of this research. The official result of the study is a set of ten core inflation indexes which responds all the expected properties and seem optimal for the inflation forecasts. Another result that goes beyond our expectation is that one of these ten indexes has a dual function i.e. a good predictor of inflation and a public index of inflation. A supplementary contribution of this thesis is a list of important remarks concerning the estimation technique of core inflation that is applicable in the case of Vietnam.
