Abstract
This dissertation consists of four essays, focusing on the relationship between financial risks, financial market uncertainty and macroeconomic conditions. The first essay estimates the effects of anticipated and unanticipated monetary policy changes on jump variation by employing high frequency non-parametric jump detection methods. We use an event study approach and a structural VAR framework in examining stock price jump variation for the aggregate economy, the financial, health, energy and telecommunication-information technology sectors (Tel-Info). We find that anticipated changes in the Fed funds have no significant effect on jumps. In contrast, jump variation in the price of financial market data increases with monetary policy surprises. We document evidence of asymmetries in the response of jumps to monetary policy changes. Monetary policy surprises and positive changes in the Fed target rate induce increment in jumps. Similar results exist in the sector analysis. In addition, this study uncovers no evidence of endogenous response between jumps and monetary policy surprises. The second essay estimates the response of uncertainty/risk aversion to monetary policy actions in both the financial sector and the aggregate economy using a Structural Vector Autoregressive (SVAR) model. When compared with other sectors, our constructs reveal that financial risk aversion/uncertainty has greater correlation with the aggregate risk aversion and uncertainty. Our analysis reveals that financial risk aversion and uncertainty exhibit stronger interdependence with monetary policy actions than aggregate uncertainty and risk aversion. The third essay provides the dynamic characterization of the link between ex-ante financial distress risk and the real economy. Using 219, 990 firm-year observations, an ex-ante measure of financial distress is generated at sector level. By employing simultaneous equation model, we provide a comprehensive set-up for predicting ex-ante financial distress risk and examining its effect on GDP growth. Over the period of 1970-2012, the results from the US firms reveal that ex-ante financial distress strongly relate to GDP growth. Ex-ante distress risk contracts GDP growth by up to 10%. Similar contractions in the growth of GDP are uncovered when a single equation approach is used in establishing the relationship between financial distress and growth in GDP. In addition, the results remain consistent when a confirmatory analysis is generated by using a weighted sector index of financial distress. The fourth essay examines liquidity risk and financial integration using bank level flows for 95 countries. The results suggest that global banking network influences liquidity risk. The more the banks are connected to each other the more they are prone to liquidity risk and the result is the same for intermediaries in the network formation. Borrowers that connect to important lenders are not at an advantage, but banks that have independent access to finance in the financial network are at an advantage. On a regional basis, banks in Europe, Africa and Asia and Pacific that have strong connections are prone to liquidity risk. American banks that function as intermediary in the network are prone to liquidity risk. Banks in the American region that have independent access to financing in the financial network are able to reduce liquidity creation, but their degree of connectivity worsens net stable funding.
