This thesis investigates the role of the exchange rate and interest rate channels in the monetary transmission mechanism in Ukraine. The responses on the domes- tic as well as Russian economy shocks are estimated using the Vector Autoregression Model with block-exogeneity restriction. Monetary transmission did not prove to be strongly effective via neither of the estimated channels, although the exchange rate channel demonstrates the results which are more in line with the economic theory. In addition, the exchange rate channel shows the higher and more significant pass through. Further, we estimate the importance of the shocks of both home and for- eign economies for the domestic variables deviations using variance decomposition technique. The relevance of the Russian shocks in fluctuations of home variables is found out. The current estimation of the transmission mechanism is relevant due to the planned inflation targeting regime implementation in Ukraine which requires understanding of that processes in the economy. 1

This study discusses the monetary policy transmission mechanism in the different channels. The analysis is conducted using generalized impulse response functions derived from a factor-augmented vector error correction (FAVECM) model. The FAVECM methodology as developed by Lee (2009) extends the factoraugmented vector autoregression (FAVAR) model to analyze long-run and shortrun dynamics of non-stationary variables. This recenly derived FAVECM model combines the advantages of factor model and the VECM model. The estimations are conducted using 174 macroeconomic time series in monthly frequency for the period January 2000 to September 2009. Results indicate that interbank call loan rate, deposit rate and prime lending rate are conintegrated, which provides sufficient evidence of the existence of the credit channel in monetary transmission system. Other GIRF results are generally consistent of the expected monetary policy effectiveness.

This study revists Purchasing Power Parity (PPP) and discusses the monetary policy transmission mechanism in exchange rate channels. The analysis is conducted using generalized impulse response functions derived from a Factor- Augmented Vector Error Correction (FAVECM) model.

This recently derived FAVECM model combines the advantages of factor model and the VECM model. The estimations are conducted using 157 macroeconomic time series in monthly frequency for the period January 2000 to September 2009. Results indicate that PPP exists and expansionary devaluation effect in Taiwan. Other GIRF results are generally consistent of the expected exchange rate effectiveness.

This paper applies a Factor-augmented error correction model proposed by Banerjee. A, Marcellino. M¡]2009¡^to measure the impact of the United States¡¦ monetary policy on Taiwan. The FECM model has the following advantages. First, it has refined the dynamic factor model, since it allows us to include the error correction terms into equation. Second, we can improve FAVAR model¡¦s shortcomings, the common factor lack of economic interpretation, by using the method of Belviso. F, Milani. F¡]2006¡^. Third, the cointegration can analyze long-run and short-run dynamics of non-stationary variables. Forth, we propose the generalized impulse respone to analyze the FECM model, it doesn¡¦t require orthogonalization of shocks and is invariant to the ordering of the variables. Finally, we indeed prove the interest rate channel does exist in Taiwan and United States through the method of FECM model.

The primary objective of this thesis is to analyse the relationship between money and the macro-economy in Sri Lanka between 1977 and 1985, in order to identify the paths through which monetary policy impulses are transmitted over this period. In doing so, - we also hope to highlight the use of macro-simulation as a tool for the analysis of the monetary transmission mechanism and to emphasise the importance of formulating monetary policy within an explicit monetary control framework. This is especially important in Sri Lanka since monetary policy has been a key instrument of demand management since 1977 and historically there has been a noticeable absence of an explicit monetary control framework. Empirical research on the monetary transmission mechanism has been very limited as far as developing countries are concerned. An exception here is the SEACEN (1981) study which simulates the effects of monetary shocks on a number of South East Asian countries, including Sri Lanka, using a flexible monetarist approach. Our research is based upon a revision of the specification of this model for Sri Lanka and a more comprehensive disaggregation of the monetary transmission channels. Our empirical model produces statistical results which are generally acceptable and conform to a Priori expectations. This model is then simulated dynamically, both, to validate the equations in the context of a complete model and to quantify the impact of alternative policy scenarios relating to the monetary transmission mechanism in Sri Lanka. We believe that our results will help to shed light on the nature of the monetary transmission mechanism in developing countries as well as provide the basis for an on-going analysis of monetary management in Sri Lanka. / Central Bank of Sri Lanka

Bakgrund: I november 2014 beslutade Riksbanken att ta steget mot en nollränta och i februari 2015 gick Riksbanken ut med ytterligare en sänkning till -0,10 procent. På så vis fick Sverige för första gången en negativ reporänta. Enligt makroekonomisk teori ska en sänkning av reporäntan stimulera konsumtion och investeringar i ekonomin. Huruvida reporäntan och dess räntesänkningar skapar förutsättningar för företag att investera är ett aktuellt och viktigt forskningsområde. Forskningen i ämnet är tunn på den svenska marknaden och således är forskningsbidraget från denna studie av betydelse.Syfte: Syftet med studien är att undersöka och analysera hur förändringar i reporänta, makro-ekonomiska faktorer samt finansiella indikatorer påverkar investeringar hos svenska företag.Genomförande: Studien bygger på en kvantitativ metod. En Vector Autoregressive model har skapats för att redogöra hur reporäntan, de makroekonomiska faktorerna och de finansiella indikatorerna påverkar företagens investeringar. För att möjliggöra en analys av dessa effekter har impulse response functions skattats i modellen. På så vis undersöks det hur en isolerad enhetsökning i de valda variablerna påverkar företagens investeringar över flera tidsperioder. För att genomföra en mer omfattande analys skattas tre modeller där den första tar hänsyn till både makroekonomiska faktorer och finansiella indikatorer. Den andra modellen exkluderar de finansiella indikatorerna och den tredje modellen speglar reporäntans utveckling i två olika tidsperioder.Resultat: Företagens investeringar påverkas av flertalet faktorer. En enhetsökning av utlåningsräntan, växelkursen och företagens inflationsförväntningar uppvisar ett signifikant negativt samband. En enhetsökning av BNP-tillväxten visar däremot ett signifikant positivt samband. Reporäntan visar ingen direkt effekt på investeringar i de första två modellerna. Däremot uppvisar reporäntan skillnader i den tredje modellen, där ett negativt samband förekommer i den första av de två observerade tidsperioderna. / Background: The central bank of Sweden decided in November 2014 to set the repo rate close to zero. Further they decided to lower the repo rate to -0,10 percent in February 2015. In regard to this, Sweden had a negative repo rate for the first time. According to macroeconomic theory a decrease in the repo rate is performed to stimulate an economy’s investments and consumptions. Whether or not a decrease in interest rates gives greater incentives for firms to invest is a topical subject and an important field of research. In addition to this, the existing research on the Swedish market is insufficient within this field, which gives us further motives to conduct this study.Aim: The purpose of this study is to examine and analyse how changes in the repo rate, macroeconomic factors and financial indicators affects investments of Swedish firms.Completion: The study is conducted with a quantitative approach. A Vector Autoregressive model is created in order to examine the impact of changes in the repo rate, the macroeconomic factors and the financial indicators on firms’ investments. Impulse response functions are estimated to allow a further analysis of these effects. Hence, it is conceivable to examine how one isolated unit-increase in a specific variable affects firms’ investment through several time periods. Furthermore, we estimate three models, one which includes both macroeconomic variables and financial indicators and another which excludes the financial indicators. The last model reflects the repo rate’s impact on investments in two separate time periods.Result: Investments of firms are affected by numerous of factors. One unit-increase of the lending rate, the exchange rate and firms’ expectations of inflation exhibit a negative relation to investments. Furthermore, one unit-increase in GDP-growth tends to increase investments. However, the repo rate has no impact on investments in the first two models. In spite of this, evidence from the third model indicates that the repo rate has a negative impact on investments during the first period.

In an effort to examine role of capital markets' efficiency in transmission of monetary policy, 28 time series of market efficiency development are estimated with use of long-term memory and fractal dimension measures and a panel of 27 inflation targeting countries is constructed to run a random effect regres- sion. The cases of Czech Republic and Austria are thereafter more closely examined with use a vector-autoregressive and threshold vector-autoregressive frameworks on macroeconomic data spanning from 1996:Q3 to 2018:Q4. The evidence obtained through the conducted analyses support the hypothesis, that a more efficiently functioning capital market better contributes to monetary policy pass-through, or conversely, that high transaction costs, barriers to cap- ital market entry, or poor information availability may hinder the effects of central bank's monetary policy.

The goal of this thesis is to identify domestic and foreign shocks that mostly explain variation in the Czech price level. This goal is accomplished by the use of structural vector autoregression. As the Czech Republic is considered to be a small open economy, it is crucial to include foreign variables into the model which are represented by shocks in euro zone. Furthermore, a block exogeneity restriction is imposed because it is unlikely that shocks in the Czech economy can influence macroeconomic development in euro zone. The results of the thesis indicate that foreign shocks explain 70% variability in Czech price level out of which 50% is explained by euro zone's price level shocks. It is likely that in near future Czech economy will experience deflation for a while. Nevertheless, by 2018 Czech inflation rate should be in 1-3% band.

本文主要研究日本央行實施緊縮性貨幣政策時，日本銀行業貸款組合變動與對實質經濟影響之關係，透過比較貨幣性衝擊、單純產出衰退及總和需求衰退對於銀行貸款組合的影響，以分析銀行在貨幣政策所發揮的功能。經VAR模型實證結果顯示，日本國內貨幣緊縮會使短期實質產出衰退、價格上升；銀行對於家計部門消費信用以及購屋貸款的放款減少、對企業的放款則增加。進一步檢驗不同規模企業貸款發現，銀行對大型企業的放款較為寬鬆，而對於中小企業的放款增幅較不明顯。另一方面，考慮信用標準擴散指數的VAR模型分析發現，日本國內的貨幣緊縮政策使銀行對於家計單位信用標準趨於嚴格的程度最大，再來依序為中型企業、小型企業及大型企業。這些實證結果支持銀行信用管道的存在，也說明銀行在貨幣傳遞機制中扮演重要的角色。 / The paper mainly studies the relationship between the change of Japanese bank loan portfolios and its substantial effect on economy during implementation of monetary tightening policy by Japan authority. Through comparison of monetary impacts, as well as the effects of the downturns in both output and real demand on bank loan portfolios, with the downturns are generated in a way that they produce the same dynamic real output and final demand path as that from a monetary downturn. The empirical results of VAR model reveal that the domestic monetary tightening in Japan would cause decrease in short-term real output and price level rise. General banks offer less consumption credits and house loans for households, but turn to increase loans for enterprises. When further examining the loans for enterprises of different scales, the paper finds that the banks take a looser attitude in offering loans to large-scale enterprises than to small and medium enterprises (SMEs), whose loans seem to have insignificant increase. On the other hand, after analysis of VAR model that considers the credit standard diffusion index, it is found that because of the domestic monetary tightening policy of Japan, the banks’ practices in their offer of credits appear to be strictest to households, and then less strict to SMEs and large enterprises. These facts prove the existence of credit channels of banks, and show the important roles that banks take in monetary transmission mechanism.
