Three essays on bayesian econometrics

Abstract

This thesis deals with the subject of Bayesian econometric methods in time-series analysis in the field of economics and finance. Each chapter constitutes an independent empirical application conducted in a Bayesian framework. In the first chapter, we employ a Bayesian time-varying parameter Vector Autoregressive (TVP-VAR) model to examine the relation between the price of oil and investor sentiment. To measure investor sentiment, we construct a new proxy based on the search patterns of individuals on the Google engine. Using this new proxy, oil prices as well as benchmark macroeconomic and financial variables, we estimate a TVP-VAR that takes into account the changes in the transmission of investors sentiment shocks to oil prices over time. The results indicate that an unexpected increase in investor attention yields a long-lasting increase both in the price of oil and the stock market returns. In the second chapter, we use alternative Bayesian Markov- witching Generalised Autoregress ...
