Essays on Inflation Dynamics and Monetary Policy in a Globalized World


Book Description

The aim of this thesis is to analyze the impact of globalization on the dynamics of inflation and monetary policy in a globalized world. It consists of three essays.In the first essay we investigate the impact of financial globalization on the behaviour of inflation targeting emerging market economies with respect to exchange rate - Do central banks respond to exchange rate movements or not? We use quarterly data for six emerging market inflation targeting economies from the date of their inflation targeting adoption to 2009 Q4. The chapter uses small open economy new Keynesian model à la Gali and Monacelli (2005), and employs multi-equation GMM technique to investigate the relationship. We find that the response of central bank to the exchange rate in case of Brazil, Chile, Mexico and Thailand is statistically significant while insignificant for Korea and Czech Republic. Theoretically, it should not be so as even under flexible inflation targeting central bank responds to inflation deviation and output gap; we think that the peculiar characteristics of emerging markets, like fear of floating, weak financial system and low level of central bank credibility make exchange rate important for these economies. In the second essay we investigate empirically the relative importance of monetary transmission channels for Brazil, Chile and Korea. This chapter uses monthly data from the inception of inflation targeting regime to 2009 M12. We use a SVAR model incorporating the main monetary transmission channels combined together instead of individual channels in isolation. The empirical results indicate that the exchange rate channel and the share price channel have higher relative importance than the traditional interest rate and credit channel for industrial production. The results are not much different in case of inflation, except for Korea. The high ranking of exchange rate and share price channel is in line with the results by Gudmundsson (2007), which finds that exchange rate channel might have overburdened in the wake of financial globalization.In the third chapter we investigate empirically the role of openness - real and financial - on the inflation dynamics of Brazil, Chile and Korea. The chapter uses monthly data from the inception of inflation targeting regime to the end month of 2009. In this chapter we employ the Generalized Method of Moments (GMM) technique. We use imports to GDP ratio as an indicator for real openness whereas Chinn and Ito index (KAOPEN) and total assets plus total liabilities to GDP ratio form the data set of Lane and Milesi-Ferretti are two proxies for financial openness. The chapter concludes that there exists, generally, a positive relationship between real openness and inflation. However, in case of financial globalization the results are inconclusive as they are sensitive to measurement method of financial globalization.




Essays on Monetary Policy Rules and Inflation Dynamics


Book Description

There has been a growing trend to utilize nonlinear models to analyze key issues in monetary policy and international macroeconomics. Using traditional linear models to understand nonlinear relationships can often lead to inaccurate inference and erroneous policy recommendations. The three essays in this dissertation explore nonlinearity in the Federal Reserve’s policy response as well as between a country’s inflation dynamics and integration in the global economy. My aim in accounting for potential nonlinearity is to get a better understanding of the policy makers’ opportunistic approach to monetary policy and evaluate the inflation globalization hypothesis, which basically predicts that global factors will eventually replace the domestic determinants of inflation. In the first essay I develop abroad nonlinear Taylor rule framework, in conjunction with real time data, to examine the Fed’s policy response during the Great Moderation. My flexible framework is also able to convincingly show that the Fed departed from the Taylor rule during key periods in the Great Moderation as well as in the recent financial crisis. The second essay uses a threshold methodology to investigate the importance of nonlinear effects in the analysis of the inflation globalization hypothesis. Finally the third essay investigates the relationship between inflation and globalization, under an open-economy Phillips Curve framework, for a panel of OECD countries with a dynamic panel GMM methodology. Contrary to most of the previous literature, which ignores such nonlinearities, my new approach provides some interesting empirical evidence supportive of the effect globalization has on a country’s inflation dynamics.










Essays on Inflation Dynamics, Economic Fluctuations and Fiscal Policy


Book Description

Inflation dynamics and the quantitative effects of fiscal policy remain topics of debates. The mixed results may due to the use of inappropriate models. To reconcile the mixed estimates of inflation dynamics, I generalized a hybrid New Keynesian Phillips Curve model developed by Gali and Gertler (1999) with time varying parameters. I find the model with fixed parameters is possibly a misspecified model since the estimated parameters are not stable over time. In consequence, a suitable model for explaining inflation dynamics should account for the time varying feature of parameters. To further investigate the mixed results on the quantitative effects of fiscal policy, I use a sophisticated DSGE model proposed by Smets and Wouters (2007), and simplify it to other 15 DSGE sub-models by imposing a tight prior on a single parameter or a combination of tight priors on multiple parameters. I estimate all sixteen models using Bayesian approach and obtain the qualitative and quantitative effect of fiscal stimulus in all models, which are comparable with currently empirical studies. I pick up a suitable model via Bayes factor and then forecast the effect of fiscal stimulus in a scenario looks like U.S. 2008/2009 economic recessions. I find a positive short-run effect but a negative long run consequence of fiscal stimulus.




Essays on Inflation Volatility


Book Description

Inflation volatility is one of the key constituents of inflation dynamics and has not received much attention in the literature. The study of inflation volatility is important because it has adverse economic consequences. This thesis aims to study the determinants of inflation volatility for advanced and developing countries. At the outset, I explore the empirical regularities of inflation volatility based on monthly and quarterly CPI inflation data (1968 to 2011) using time and frequency domain analysis. I establish a stylised fact that inflation is significantly more volatile in developing countries than advanced countries. This raises a research question why it is so. Using a New Keynesian paradigm, an answer to this research question is sought from two angles. First, a policy rule for interest rate (known as Taylor rule) is estimated over a balanced panel of advanced and developing countries to examine the difference in policy activism between these two groups of countries. This follows from the New Keynesian argument that an active monetary policy is a necessary condition for stable dynamics of inflation. Using the Generalized Method of Moments and the Arellano and Bover (1995) method of dynamic panel estimation, I find that monetary policy is active in advanced countries but passive in developing economies. This striking difference in the policy regimes between these two groups can be one of the reasons for the difference in inflation volatility. Second, motivated by the asymmetry in consumption basket of CPI between advanced and developing economies, a two-sector New Keynesian model with food and non-food is developed. The model features: i) composite consumption and labour index, ii) differential Calvo-type price adjustment of firms across sectors, and iii) Taylor type monetary policy rule. Characterising the distinct structures of advanced and developing economies by two different parameterizations, the model calibration shows that demand disturbance generated by the preference shock is one of the fundamental forces for inflation volatility. In addition, my simulation analysis demonstrates that other structural parameters such as the frequency of price adjustment, distribution of labour and the elasticity of labour substitution, and the policy parameter of inflation in the Taylor rule are also critical factors explaining the greater volatility of inflation in developing economies.




Inflation in Emerging and Developing Economies


Book Description

This is the first comprehensive study in the context of EMDEs that covers, in one consistent framework, the evolution and global and domestic drivers of inflation, the role of expectations, exchange rate pass-through and policy implications. In addition, the report analyzes inflation and monetary policy related challenges in LICs. The report documents three major findings: In First, EMDE disinflation over the past four decades was to a significant degree a result of favorable external developments, pointing to the risk of rising EMDE inflation if global inflation were to increase. In particular, the decline in EMDE inflation has been supported by broad-based global disinflation amid rapid international trade and financial integration and the disruption caused by the global financial crisis. While domestic factors continue to be the main drivers of short-term movements in EMDE inflation, the role of global factors has risen by one-half between the 1970s and the 2000s. On average, global shocks, especially oil price swings and global demand shocks have accounted for more than one-quarter of domestic inflation variatio--and more in countries with stronger global linkages and greater reliance on commodity imports. In LICs, global food and energy price shocks accounted for another 12 percent of core inflation variatio--half more than in advanced economies and one-fifth more than in non-LIC EMDEs. Second, inflation expectations continue to be less well-anchored in EMDEs than in advanced economies, although a move to inflation targeting and better fiscal frameworks has helped strengthen monetary policy credibility. Lower monetary policy credibility and exchange rate flexibility have also been associated with higher pass-through of exchange rate shocks into domestic inflation in the event of global shocks, which have accounted for half of EMDE exchange rate variation. Third, in part because of poorly anchored inflation expectations, the transmission of global commodity price shocks to domestic LIC inflation (combined with unintended consequences of other government policies) can have material implications for poverty: the global food price spikes in 2010-11 tipped roughly 8 million people into poverty.

International Capital Flows


Book Description

Recent changes in technology, along with the opening up of many regions previously closed to investment, have led to explosive growth in the international movement of capital. Flows from foreign direct investment and debt and equity financing can bring countries substantial gains by augmenting local savings and by improving technology and incentives. Investing companies acquire market access, lower cost inputs, and opportunities for profitable introductions of production methods in the countries where they invest. But, as was underscored recently by the economic and financial crises in several Asian countries, capital flows can also bring risks. Although there is no simple explanation of the currency crisis in Asia, it is clear that fixed exchange rates and chronic deficits increased the likelihood of a breakdown. Similarly, during the 1970s, the United States and other industrial countries loaned OPEC surpluses to borrowers in Latin America. But when the U.S. Federal Reserve raised interest rates to control soaring inflation, the result was a widespread debt moratorium in Latin America as many countries throughout the region struggled to pay the high interest on their foreign loans. International Capital Flows contains recent work by eminent scholars and practitioners on the experience of capital flows to Latin America, Asia, and eastern Europe. These papers discuss the role of banks, equity markets, and foreign direct investment in international capital flows, and the risks that investors and others face with these transactions. By focusing on capital flows' productivity and determinants, and the policy issues they raise, this collection is a valuable resource for economists, policymakers, and financial market participants.
