<p>This dissertation computes the optimal monetary and fiscal policy for small open and emerging economies in an estimated medium-scale model. The model departs from the conventional approach as it encompasses all the major nominal and real rigidities normally found in the literature in a single framework. After estimating the model using Bayesian techniques for one small open economy and one emerging economy, the Ramsey solution for the optimal monetary and fiscal policy is computed. Results show that foreign shocks have a strong influence in the dynamics of emerging economies, when compared to the designed optimal policy for a developed small open economy. For both economies, inflation is low, but very volatile, while taxes follow the traditional results in the literature with high taxes over labor income and low taxes for capital income.</p> / Dissertation

<p>This dissertation is a collection of essays with the main objective of estimate and understand macroeconomic behavior of emerging countries by the lenses of modern tools in general equilibrium modeling.</p><p>In the first chapter, I study whether structural parameters of Small Open Economy Real Business Cycle models are constant when applied to Emerging Markets data. Using data from Argentina, I estimate a small open economy model with trend shocks and working capital constraints, augmented with time varying parameters. I find that so called ``structural" parameters suffer substantial changes in the period 1983-2008. Structural instabilities arise from both technological and financial sources. Given these findings, I inquire which are the features of the data that parameter drifts capture. I review emerging markets facts and find parameter instabilities play a key role in addressing for the variability observed in the data.</p><p>In the second chapter, I study policy changes in emerging countries. Motivated by the repeated stabilization programs implemented by emerging economies during the last 30 years, I develop a dynamic stochastic general equilibrium model with Markov-Switching to study fiscal and monetary policies in emerging economies. I estimate the model for Mexico and find strong evidence of policy changes. Two Regimes are identified. The Active Monetary Policy Regime (AMP), in which monetary and fiscal policies respond to inflation and government debt, respectively; and the Active Fiscal Policy Regime (AFP), in which fiscal policy does not respond to government debt and monetary policy does not respond to inflation. AMP holds during short periods of time after macroeconomic crises during the 80s and 90s, and for a long period after 2002. The rest of the periods, AFP is in effect. I find that switches from AFP to AMP have strong stabilization effects at the cost of high output losses. Moreover, credibility in the persistence of the regime change is key to assess the effectiveness of the stabilization program.</p> / Dissertation

In the process of China's rapid economic growth, Chinese Communist Party implemented a series of macro-economic policies --- fiscal policies and monetary policies --- to regulate its economy. As a result, it safely passed through the Asian financial crisis in 1997 and the world financial tsunami in 2008, and was able to continue steady growth. This dissertation focuses, under the Chinese Communist economic system, on how to apply the macro policy to control its growth and what has been the practical impact. What role is macro-control playing in the process of China's economic development? Macro-economic policy is actually the main driving force behind China's economic performance. This dissertation emphasizes that under China's unique political economy, macro-control leads China's rapid economic growth. Nevertheless, due to China's economic structure of market imperfections, and the lack of inherent stability of the market mechanism, the Chinese macroeconomic regulation and control has easily lead to economic volatility and to a possible hard crash in years ahead. Although the experience accumulated so far has led to a relatively stable economy, the economic structure is still incomplete. This dissertation argues that China's macro-control¡¦s aggregate demand in driving China's economy needs to be adjusted from investment and export to personal consumption in order to contribute to sustainable economic development in the future.

In this thesis, sustainability of the Turkish domestic debt is analyzed within the &ldquo / sustainability indicators&rdquo / perspective. The fiscal targets of Maastricht Treaty (1992) are imposed on the Turkish fiscal policy and it is investigated whether these targets are the indicators for sustainability in the medium term. Uctum and Wickens&rsquo / (2000) methodology is followed in assessing the sustainability of the current fiscal policy and the efficiency of the Maastricht Treaty (1992) targets. Moreover, the vector auto regression (VAR) approach of Garcia and Rigobon (2004) is utilized in deriving the econometric model for the debt dynamics of Turkey. The results suggest that domestic debt of Turkey has been unsustainable within 1994-2008. Furthermore, the Maastricht Treaty (1992) fiscal targets are binding for Turkey and gaining more significance in the recent years.

Macroeconomic events in the United States during the last ten years—the housing bubble, the financial crisis and the subsequent, deep recession—brought several puzzles to the attention of economists and policymakers. Why were there such large price booms and busts in places like Las Vegas and Phoenix, where land was readily available and construction markets were very active? Why are economies so slow to recover from recessions that coincide with financial crises? Can policymakers use fiscal stimulus to increase output and accelerate economic recovery after a recession?
