요약This dissertation develops new econometric methods and empirical applications in macroeconomic forecasting, economic uncertainty measurement, and decentralized finance (DeFi) market microstructure.In the first chapter, we introduce a heterogeneous coefficients model within the sparse-group LASSO MIDAS framework to address cross-sectional heterogeneity in mixed-frequency panel data regression. By allowing coefficient similarity within predefined economic groups while maintaining flexibility where needed, our model provides a structured compromise between fully pooled and fully heterogeneous specifications. We apply this methodology to macroeconomic panel forecasting, demonstrating its advantages in capturing meaningful heterogeneous relationships while mitigating biases introduced by overly restrictive pooling assumptions. Our results highlight the trade-off between model flexibility and generalizability in high-dimensional economic forecasting applications.In the second chapter, we develop novel measures of economic uncertainty at the state and extended metropolitan area (EMA) levels, leveraging forecast errors from GDP growth models. Using a sparse-group LASSO MIDAS regression framework, we estimate state-level uncertainty and construct an EMA-level uncertainty measure to capture economic volatility at different regional scales. Our empirical analysis identifies key macroeconomic drivers of uncertainty, including policy instability, industry composition, and financial conditions. We further validate our EMA uncertainty measure by comparing it with established uncertainty indices, demonstrating its effectiveness in capturing crisis-driven fluctuations. These findings contribute to the broader literature on macroeconomic uncertainty and regional economic dynamics.In the third chapter, we examine the price impact of trades on decentralized exchanges (DEXs) using Uniswap as a case study. Despite the deterministic nature of automated market makers, realized price impact remains uncertain due to block inclusion and transaction ordering mechanisms. We quantify the information advantage of Miner Extractable Value (MEV) traders, who exploit pending orders for arbitrage. To address limitations in traditional vector autoregression (VAR) models of price impact, we propose a novel empirical framework that accounts for differential price effects based on trader type. Our findings provide strong evidence that MEV traders play a dominant role in price discovery on DEX markets, contributing to the literature on market microstructure in digital asset markets.This dissertation advances econometric methodology for high-dimensional panel regressions, provides new insights into economic uncertainty at regional levels, and offers empirical evidence on price formation in DeFi markets. The findings have implications for macroeconomic forecasting, regional economic policy, and digital asset market analysis.
