The present paper has attempted to provide an empirically argumented basis on the existing conflict about effectiveness of IT regime on lowering inflation and inflation volatility. In the first part we perform panel analysis on a group of 43 emerging and developing economies for a more recent period ranging from 1997 to 2011, distinguishing between normal and crisis times as well as between geographical regions. Differently from common studies we applied dynamic panel model specification that controls for reverse causality of regime adoption. Despite broad arguments addresing IT ineffectiveness, our results support the regime and imply that shifting to IT will lower both inflation and inflation volatility in normal times. Model specification during the external shocks was inconclusive on the selected sample with relatively recent IT history. Regarding the geographical IT performance, we outlined that regime effectiveness was uniform along analyzed regions. In the second part we perform a preliminary analysis of a developing economy IT experience and conclude that, even though there are some problems of technical nature and main policy rate is still a weak instrument of transmission channel, the Republic of Moldova chose right time for regime adoption and has made considerable progress towards the...

The aim of the thesis is to study the performance of emerging economies under the inflation targeting as a framework. This framework is characterized by the direct target that it has on inflation which should be achieved within a period. Inflation targeting was initially adopted by industrialized economies, and the outcomes throughout the years have been substantially good for other economies to join this framework. The dataset used is updated with data from after the financial crises allowing space for us to test another hypothesis about the importance of inflation targeting during the financial crises. We used difference to difference model to test our hypothesis and we concluded that inflation targeting does not have any significant statistical effect on the output growth, but it does have a statistical significant effect in the inflation rate. We also pointed out that the economies that were targeting inflation during the financial crises performed much better compared to the ones which did not.

Inflation targeting has become an increasingly popular regime among emerging markets. Focusing on the experience of inflation targeting adoption in the countries in Central and Eastern Europe and Commonwealth of Independent States, this thesis highlights the main features of the inflation targeting framework. A clear economic condition bringing these countries together is considered the dollarization issue which gains importance when designing the inflation targeting framework. The empirical study on the impact of inflation targeting in inflation, inflation volatility, output, output volatility and deposit dollarization shows clear benefits of inflation targeting in terms of inflation and inflation volatility, which are not achieved at the expense of output growth. Also, dollarization does not harm the positive impact of inflation targeting on inflation.

The thesis consists of two essays on inflation targeting. The hrst essay examines how do centrál banks set their inflation targets. Survey of centrál banks' communication regard-ing the target is presented, theoretical model is developed and finally empirical analysis is conducted on a panel of inflation targeting countries. This pioneering analysis of the topič leads us to conclusion that inflation targets are influenced by more variables than centrál banks admit. In addition to past and foreign inflation, inflation variability and GDP growth we find significant impact of centrál bank credibility and other institutional factors. The short second essay surveys literatúre assessing performance of inflation targeting and outlines perspectives of inflation targeting as a monetary policy framework. The conclusion is that if inflation targeting centrál banks stick to their best practice in transparency and communication and remain open to innovations, inflation targeting will háve a good chance to score well even in the periods of turmoil.

In Korea, an inflation targeting (IT) regime was adopted in the aftermath of the Korean currency crisis of 1997–1998. At that time, the Bank of Korea (BOK) shifted the instrument of monetary policy from monetary aggregates to interest rates. Recently, central bank policymakers have confronted more uncertainties than ever before when deciding their policy interest rates. In this monetary policy environment, it is worth exploring whether the BOK has kept a conservative posture in moving the Korean call rate target, the equivalent of the US Federal Funds rate target since the implementation of an interest rate-oriented monetary policy. Together with this, the global financial crisis (GFC) of 2007–2009 provoked by the US sub-prime mortgage market recalls the following question: should central banks pre-emptively react to a sharp increase in asset prices? Historical episodes indicate that boom-bust cycles in asset prices, in particular, house prices, can be damaging to the economy. In Korea, house prices have been evolving under uncertainties, and in the process house-price bubbles have been formed. Therefore, in recent years, central bankers and academia in Korea have paid great attention to fluctuations in asset prices. In this context, the aims of this thesis are: (i) to set up theoretical and empirical models of monetary policy under uncertainty; (ii) to examine the effect of uncertainty on the operation of monetary policy since the adoption of interest rate-oriented policy; and (iii) to investigate whether gradual adjustment in policy rates can be explained by uncertainty in Korea. Another important aim is (iv) to examine whether house-price fluctuations be taken into account in formulating monetary policy. The main findings of this thesis are summarised as follows. Firstly, as in advanced countries, the four stylised facts regarding the policy interest rate path are found in Korea: infrequent changes in policy rates; successive changes in the same direction; asymmetric adjustments in terms of the size of interest-rate changes for continuation and reversal periods; and a long pause before reversals in policy rates. These patterns of policy rates (i.e., interest-rate smoothing) characterised the central bank‘s reaction to inflation and the output gap as being less aggressive than the optimising central bank behavior would predict (Chapter 3). Secondly, uncertainty may provide a rationale for a smoother path of the policy interest rate in Korea. In particular, since the introduction of the interest rate-oriented monetary policy, the actual call money rates have shown to be similar to the optimal rate path under parameter uncertainty. Gradual movements in the policy rates do not necessarily indicate that the central bank has an interest-rate smoothing incentive. Uncertainty about the dynamic structure of the economy, which is dubbed ‗parameter uncertainty‘, could account for a considerable portion of the observed gradual movements in policy interest rates (Chapter 4). Thirdly, it is found that the greater the output-gap uncertainty, the smaller the output-gap response coefficients in the optimal policy rules, and in a similar vein, the greater inflation uncertainty, the smaller the inflation response coefficients. The optimal policy rules derived by using data without errors showed the large size of the output-gap and inflation response coefficients. This finding confirms that data uncertainty can be one of sources explaining the reasons why monetary policymakers react less aggressively in setting their interest rate instrument (Chapter 5). Finally, we found that house prices conveyed some useful information on conditions such as possible financial instability and future inflation in Korea, and the house-price shock differed from other shocks to the macroeconomy in that it had persistent impacts on the economy, consequently provoking much larger economic volatility. Empirical simulations showed that the central bank could reduce its loss values in terms of economic volatility, resulting in promoting overall economic stability when it responds more directly to fluctuations in house prices. This finding provides the reason why the central bank should give more attention to house-price fluctuations when conducting monetary policy (Chapter 6).
