This study attempts to analyze the efficiency of intervention policy in Turkey during the period between 4.1.2005 and 31.12.2012 with a sub period which is between 4.1.2007 and 31.12.2010. For our study purpose, therefore we investigated how interventions with pre-announced auctions as a whole influence the exchange rates. Further, we analyze whether there is an asymmetric effect among the buying and selling transactions with respect to their impact on the exchange rates. In the study, the E-GARCH model is employed to find the asymmetric effect. The final object of this study is whether buying auctions which are conducted to serve for only purpose of increasing international reserves influence the exchange rates. We evaluate the efficiency of transactions in the same direction of central bank statements. In conclusion, the findings did not amount to any significant impact of total transaction on exchange rates. The study findings also suggest that there is asymmetric effect among the selling and buying transactions. The amounts of selling transaction have a negative impact on both level and volatility while buying auctions did not have any significant effect on them. As a new research result, we found that buying auctions served well with respect to their contributions to reserves while they do not...

There are four chapters in my dissertation. Chapter one gives a brief introduction of the three essays. Chapter two empirically analyzes the interaction among conventional monetary policy, foreign exchange intervention and the exchange rate in a unifying model for Japan. I have several findings. First, the results lend support to the leaning-against-the-wind hypothesis. Second, conventional monetary policy has as great influence on the exchange rate as foreign exchange intervention in Japan. Third, intervention in Japan is ineffective or may be counter-effective, so escaping liquidity trap by intervention alone may not be a feasible way. Chapter three empirically identifies the sources of exchange rate movements of Japan vis--vis the US, and investigates the role of the exchange rate in the macro economy adjustment. It finds that real shocks dominate nominal shocks in explaining the exchange rate movements, with relative real demand shocks as the major contributor. And the exchange rate market does not create many shocks. The overall result supports that the bilateral exchange rate in Japan is a shock-absorber rather than a source of shock. Chapter four provides cross-country and time-series evidence on the extent of exchange rate pass-through at different stages of distribution - import prices, producer prices and consumer prices - for eight major industrial countries: United States, Japan, Canada, Italy, UK, Finland, Sweden and Spain. I find exchange rate pass-through incomplete in many horizons, though complete pass-through is observed occasionally. The degree of pass-through declines and time needed for complete pass-through lengthens along the distribution chain. Furthermore, I find that a greater pass-through coefficient is associated with an economy that is smaller in size with higher import shares, more persistent and less volatile exchange rate shocks, more volatile monetary shocks, higher inflation rate, and less volatile GDP.

[pt] Essa dissertação investiga os efeitos da intervenção cambial esterilizada do Banco Central sobre a cotação da taxa de câmbio do Real contra o Dólar. Os resultados sugerem que este é um instrumento independente de política econômica, porém com efetividade limitada. Ainda, é verificada a consistência desses efeitos com a principal teoria de explicação dos efeitos da intervenção sobre a taxa de câmbio: o efeito de portfólio. Por fim, é analisado como a exposição dos Bancos à moeda estrangeira se relaciona com diferenciais cobertos de taxa de juros, e qual a relação do processo de intervenção com esses diferenciais. / [en] This study investigates the effect of the brazilian central bank sterilized exchange rate intervention on the R$/US$ exchange rate. The results suggest that it is an independent economic policy device, yet with limited effectiveness. We verify the consistency of the effects with the portfolio balance exchange rate determination theory. We find that the foreign exchange exposure of local banks is related to covered interest parity differentials, and the size of those differentials is related to the intervention process.

This thesis deals with CNB foreign-exchange intervention from November 2013 in context of assumptions and impacts on the Czech economy. The theoretical part presents important monetary policy aspects, from conventional and unconventional tools to inflation targeting and deflation, to understand theoretical framework of analysis. Analytic part takes a look on Czech economy condition before interventions, especially inflation. Intervention impacts and exit strategies are examined further. Based on the analyzed data this thesis concludes that foreign-exchange interventions by Czech National Bank were not necessary and inevitable action.

The aim of this paper is to find out, if the foreign exchange intervention executed by Czech National Bank influenced car sales in Czech Republic. Similar research was not examined by any author so far. The study analyze the case of four most sold car brands in Czech Republic (Hyundai, Skoda, Volkswagen, Opel) between the years 2012 and 2014. Positive impact of the intervention was found out in two cases.

The 2008-2009 crisis showed that the main macroeconomic challenge facing an economy such as Peru's is the management of external shocks that deteriorate the balance of payments and reduce aggregate demand. The aim of this paper is to discuss what the monetary policy response to theseexternal shocks should be. Since inflation targeting was implemented in 2002, the most important instrument of Peruvian monetary policy has been a short-term interest rate. Another key instrument of monetary policy has been sterilized intervention in the foreign exchange market. In order to compare the different monetary policy responses to external shocks, these central bank instruments are incorporated into a textbook IS-LM-BP model. This model is adapted to the financial conditions of an economy such as Peru’s, which has a banking system that operates in both domestic and foreign currency.The conclusion of this paper, in keeping with that of Blanchard et al. (2010), is that a monetary policy which combines a Taylor rule for setting the interest rate, aimed at internal equilibrium, with a foreign exchange intervention policy of leaning against the wind, aimed at external equilibrium, can stabilize both price levels and economic activity in the face of external shocks.The central bank should reduce the interest rate and sell foreign currency to face adverse external shocks, and should raise the interest rate and buy foreign currency to face favorable external shocks. / La crisis de 2008-2009 demostró que el principal desafío macroeconómico que enfrenta una economía como la peruana es el manejo de los choques externos adversos que deterioran la balanzade pagos y reducen la demanda agregada. El objetivo de este artículo es discutir cual debiera ser la respuesta de política monetaria a estos choques externos. Desde que se implementó el sistema de metas de inflación en 2002, el instrumento principal dela política monetaria peruana ha sido una tasa de interés corto plazo. La otra herramienta clave de la política monetaria ha sido la intervención esterilizada en el mercado cambiario. Para comparar las respuestas de política monetaria ante los choques externos adversos, se incorporan estos diversos instrumentos del banco central en un modelo IS-LM-BP, similar al del libro de texto. Este modelo es adaptado a las condiciones financieras de una economía como la peruana que tiene un sistema bancario que opera en moneda nacional y extranjera. La conclusión del texto es que una política monetaria, como la sugerida por Blanchard et al (2010), que combine una regla de Taylor para el manejo de la tasa de interés, dirigida al equilibrio interno, con una regla de intervención cambiaria que rema en contra de la corriente, dirigida al equilibrio externo, puede estabilizar el nivel de precios y la actividad económica ante los choques externos. El banco central debe reducir la tasa de interés y vender moneda extranjera ante choques externos adversos y debe subir la tasa de interés y comprar moneda extranjera ante choques externos favorables.

[pt] Foco de grandes controvérsias quanto seus efeitos sobre a taxa de câmbio, as intervenções cambiais tem sido amplamente utilizadas no processo de recomposição de reservas internacionais brasileiras. Muito embora não seja o principal objetivo do Banco Central do Brasil afetar o nível da taxa de câmbio, é possível que isso ocorra. Portanto, este trabalho busca responder à seguinte indagação: teriam as intervenções cambiais esterilizadas efeitos sobre a taxa de câmbio? Os resultados encontrados dão indícios de que tais efeitos existem, mas são de magnitude muito reduzida e de curta duração. / [en] Central object of big controversies regarding its effects on the exchange rate, sterilized interventions have been largely used by Brazil`s Central Bank on the buildup of the country`s international reserves. Although it is not his objective to affect the exchange rate level when buying foreign currency, there is a chance that it might happen. In this line, the primary question of this work is: Does sterilized interventions on the exchange market affect the exchange rate? The found results give some evidence that such effects exist, but are very small on its magnitude and of low duration.

Study analyses the influence of the real exchange rate on the real trade balance between the Czech Republic and Germany, using quarterly data for the period 2000 -- 2014. Previous empirical studies are summarized and their method is used for this analysis. Data are multiplied by consumer price index to achieve real variables and then transformed into natural logarithms. Used variables are trade balance, export, gross domestic products of the Czech Republic and Germany and dummy variables representing economic crisis during the years 2008 -- 2010 and monetary intervention of the Czech National Bank in autumn 2013. All variables were tested for stationarity and were found to be non-stationary, fortunately cointegration among variables was proved. Results failed to prove existence of J-curve concept. Results indicate, that in the short run after depreciation the real trade balance increases, but after that decreases. Economic crisis during the years 2008 -- 2010 led to decrease of the real trade balance. Intervention of the Czech National Bank did not lead in the short run to a decrease of the real trade balance. Granger causality test between the real export, the real trade balance and the real exchange rate did not prove any causal relationships.

This research paper on monetary policy focuses on strategy of inflation targeting and its modification in an environment of deflationary pressures. Focus of this paper is based on three main points that correspond to the content of individual chapters. The first point is a theoretical analysis of the main attributes of inflation targeting with emphasis on analysis of the functioning of the transmission channels. The second point is an analysis of implementation of this strategy in the Czech National Bank and in the Reserve Bank of New Zealand. In this point separate analysis was made of the development of inflation targeting and transformation of relationship between macroeconomic variables in transmission mechanism. The third point then debates the modification of monetary policy instruments in the context of inflation targeting adopted by the Czech National Bank, with an emphasis on the introduction of exchange rate commitment. Throughout the work are used simple methods for analysis with further emphasis on the actuality. The conclusion summarizes the findings and evaluates the modification of the inflation targeting strategy as a positive phenomenon in the context of evolution of monetary policy.

The main objective of this thesis is to analyze and evaluate the effect of the Czech National Bank´s foreign exchange intervention on the trade balance of the Czech Republic. For this purpose a hypothesis was set, that in the short-term the devaluation of the Czech currency causes deterioration of the trade balance and only after some time has passed the trade balance starts to grow. In theory this effect is known as the J-curve hypothesis. The first chapter summarizes theoretical knowledge about monetary policy and exchange rate theory. The second chapter analyzes the development of commodity and territorial structure of the Czech trade balance from 2000 to 2013. The third chapter focuses on the foreign exchange intervention itself and provides arguments for and against this measure taken by the Czech National Bank. The fourth chapter is the most important one for acceptance or rejection of the hypothesis set. It uses the Vector Error Correction Model to estimate the impact of devaluation on the trade balance of Czech Republic with Germany. Subsequently outcomes of this model are compared to the real statistical data of Czech trade.
