This dissertation consists of two chapters, both of which approach macroeconomic issues using simulation-based methods. Aside from the fact that each chapter contributes to its narrowly scoped field, the two chapters demonstrate an implementation of simulation-based estimation techniques and identification strategies to examine dynamic properties of unobserved economic shocks. The main objective of two chapters is to understand the properties of shock process, which in turn provides better macroeconomic implications. The first chapter structurally estimates idiosyncratic labor income risks over the life-cycle to obtain implications for a redistribution policy, namely tax and transfer systems. Since a redistribution policy provides a partial insurance to those exposed to income risks, understanding the underlying life-time labor income risks that households face is central to designing better institutional arrangements. The chapter constructs a human capital life-cycle model and structurally estimates the underlying source of labor income risks across age. We find that the estimated shock process is significantly age-dependent even after controlling for the endogenous responses to the exogenous shocks. In particular, young workers encounter a highly persistent (almost unit-root) but relatively small volatility of permanent shocks, while older workers encounter a less persistent but higher volatility of permanent shocks. In addition, we demonstrate that under the age-dependent shock process the self-insurance ability of young workers is 20% lower than that of middle-aged workers. Finally, we find that more benefits, either through a tax exemption or subsidies, to young workers drastically improve aggregate production, welfare, and income inequality. In the second chapter, we structurally estimate the dynamic properties of elasticity of substitution between capital and labor to resolve well-known puzzles in labor market dynamics: Dunlop-Tarshis phenomenon, the labor productivity puzzle, the labor share puzzle including its oveshooting response to productivity shocks, and the hours-productivity puzzle. We propose an aggregate production function that potentially takes a different shape in the short run (SR) from the long run (LR). Specifically, we allow for cyclical fluctuations of the short-run elasticity of substitution between capital and labor, [sigma][subscript t], while keeping the Cobb-Douglas shape in the long run. We find that productivity shocks are on average biased toward labor (i.e. [sigma][subscript t]

This book reflects the state of the art on nonlinear economic dynamics, financial market modelling and quantitative finance. It contains eighteen papers with topics ranging from disequilibrium macroeconomics, monetary dynamics, monopoly, financial market and limit order market models with boundedly rational heterogeneous agents to estimation, time series modelling and empirical analysis and from risk management of interest-rate products, futures price volatility and American option pricing with stochastic volatility to evaluation of risk and derivatives of electricity market. The book illustrates some of the most recent research tools in these areas and will be of interest to economists working in economic dynamics and financial market modelling, to mathematicians who are interested in applying complexity theory to economics and finance and to market practitioners and researchers in quantitative finance interested in limit order, futures and electricity market modelling, derivative pricing and risk management.

The thesis has focused on issues related to the use of external information in the identification, estimation and evaluation of Dynamic Stochastic General Equilibrium (DSGE) models, and comprises three papers. The first paper, entitled Improving Inference for Dynamic Economies with Frictions - The role of Qualitative Survey data, proposes a new inferential methodology that is robust to misspecification of the mechanism generating frictions in a dynamic stochastic economy. I derive a characterization of the model economy that provides identifying restrictions on the solution of the model that are consistent with a variety of mechanisms. I show how qualitative survey data can be linked to the expectations of agents and how this link generates an additional informative set of identifying restrictions. Moreover, I show how the framework can be used to formally validate mechanisms that generate frictions. Finally, I apply the methodology to estimate the distortions in the Spanish economy due to financial frictions and derive an optimal robust Taylor rule. The second chapter, entitled Estimation and Inference for Incomplete Structural Models using Auxiliary Density Information considers an alternative method for estimating the parameters of an equilibrium model which does not require the equilibrium decision rules and produces an estimated probability model for the observables. This is done by introducing auxiliary information about the conditional density of the observables, and using density projections. I develop and assess frequentist inference in this framework. I provide the asymptotic theory for parameter estimates for a general set of conditional projection densities and simulation exercises. In the third chapter, entitled Monetary Policy Rules and External Information, I analyze how conclusions about monetary policy stance are altered when we explicitly acknowledge that model concepts like the output gap and inflation are non-observable and we utilize many proxies that are available in the data. I document the effects on Bayesian inference of introducing such proxy information.

This dissertation consists of two essays on maximum likelihood estimation of Dynamic Stochastic General Equilibrium (DSGE) models. The first essay focuses on a monetary DSGE model of term structure, while the second essay explores and compares three different versions of New Keynesian DSGE models. In Chapter 1, a general background is given for the DSGE models, and their estimation techniques along with a review of the term structure models and New Keynesian models. The first essay, which is a joint work with Hwagyun Kim, empirically evaluates the relationships between money, inflation, output growth, and the interest rates of different maturities using a monetary DSGE model of term structure, featuring inflation targeting behavior, asset market segmentation, and external habit extended for nominal economy. This model can generate liquidity effect, average upward sloping yield curve, and time-varying bond risk premia for bearing inflation and real shocks. By exploiting the term structure equations derived from the model, the deep parameters of the model describing risk preference, inflation targeting behavior, and market segmentation between bond traders and non-traders are estimated. The model is estimated under alternative specifications: latent factors; macroeconomic factors; and both latent and macroeconomic factors. The empirical findings show that all the methods give consistent estimates of the parameters, and conclude that asset market segmentation, inflation targeting, and time-varying risk aversion are significant to account for the term structure dynamics. They also suggest that monetary factors and monetary policy are important to understand both short-run and long-run behaviors of bond prices. In the second essay, three different versions of New Keynesian DSGE models are developed, and their structural parameters are estimated by maximum likelihood estimation. Specifically, the role of velocity of money on the dynamics of real variables is empirically examined by constructing a money in the utility model and two special cases of transactions cost model. Wealth effects, previously ignored in many transactions cost models, are taken into consideration in one of the cases examined here, and comparisons are made between the transactions cost model that includes the wealth effects and the transactions cost model that ignores the wealth effects entirely. The equivalence of money in the utility model and transactions cost model with wealth effects is also quantitatively examined. The results show that there is no evidence of quantitative equivalence between these two models. Although the magnitude of impulse responses are different among the models studied here, all three models give consistent estimates for the structural parameters. The empirical findings from the maximum likelihood estimates of all three models' parameters also suggest that the velocity of money is a very important part of the IS and Phillips curves of all three models developed here, and should be included in IS and Phillips curves when examining the inflation and output dynamics.

Abstract: This dissertation examines theoretical and empirical topics in macroeconomic dynamics. A central issue in macroeconomic dynamics is understanding the sources of business cycle fluctuations. The idea that expectations about future economic fundamentals can drive business cycles dates back to the early twentieth century. However, the standard real business cycle (RBC) model fails to generate positive comovement in output, consumption, labor-hours and investment in response to news shocks. My dissertation proposes a solution to this puzzling feature of the RBC model by developing a theoretical model that can generate positive aggregate and sectoral comovement in response to news shocks. Another key issue in macroeconomic dynamics is gauging the performance of theoretical models by comparing them to empirical models. Some of the most widely used empirical models in macroeconomics are level vector autoregressive (VAR) models. However, estimated level VAR models may contain explosive roots, which is at odds with the widespread consensus among macroeconomists that roots are at most unity. My dissertation investigates the frequency of explosive roots in estimated level VAR models using Monte Carlo simulations. Additionally, it proposes a way to mitigate explosive roots. Finally, as macroeconomic datasets are relatively short, empirical models such as autoregressive models (i.e. AR or VAR models) may have substantial small-sample bias. My dissertation develops a procedure that numerically corrects the bias in the roots of AR models. This dissertation consists of three essays. The first essay develops a model based on learning-by-doing (LBD) that can generate positive comovement in output, consumption, labor-hours and investment in response to news shocks. I show that the one-sector RBC model augmented by LBD can generate aggregate comovement in response to news shock about technology. Furthermore, I show that in the two-sector RBC model, LBD along with an intratemporal adjustment cost can generate sectoral comovement in response to news about three types of shocks: i) neutral technology shocks, ii) consumption technology shocks, and iii) investment technology shocks. I show that these results hold for contemporaneous technology shocks and for different specifications of LBD. The second essay investigates the frequency of explosive roots in estimated level VAR models in the presence of stationary and nonstationary variables. Monte Carlo simulations based on datasets from the macroeconomic literature reveal that the frequency of explosive roots exceeds 40% in the presence of unit roots. Even when all the variables are stationary, the frequency of explosive roots is substantial. Furthermore, explosion increases significantly, to as much as 100% when the estimated level VAR coefficients are corrected for small-sample bias. These results suggest that researchers estimating level VAR models on macroeconomic datasets encounter explosive roots, a phenomenon that is contrary to common macroeconomic belief, with a very high frequency. Monte Carlo simulations reveal that imposing unit roots in the estimation can substantially reduce the frequency of explosion. Hence one way to mitigate explosive roots is to estimate vector error correction models. The third essay proposes a numerical procedure to correct the small-sample bias in autoregressive roots of univariate AR(p) models. I examine the median-bias properties and variability of the bias-adjusted parameters relative to the least-squares estimates. I show that the bias correction procedure substantially reduces the median-bias in impulse response functions. Furthermore, correcting the bias in roots significantly improves the median-bias in half-life, quarter-life and up-life estimates. The procedure pays a negligible-to-small price in terms of increased standard deviation for its improved median-bias properties.
