Transmission

This research has raised the question of whether the vibration transmission at a wall junction depends on how the wall is excited (by either a sound wave or a mechanical shaker). The aim of this research is to investigate this question and hence contribute to the revision of the series of standards. Villot and Guigou-Carter (2000) have considered this problem but their equations (10) and (13) appear to be in error. This research will endeavour to derive the correct equations and r epeat Villot and Guigou Carter’s calculations.

This study extends the limited finance literature on return and volatility spillover effects in China and emerging markets. It investigates the market interdependence and volatility transmissions between the Chinese stock market and other financial markets, including both domestic and international markets. The significance of this study arises from the importance of China due to its large economic scale and financial influence. To understand the behaviour of the Chinese stock market, this research has four different perspectives.

The failure of inflation targeting regimes in several emerging economies has received renewed interest among academics and policymakers alike. This ineffectiveness can be attributed to worsening fiscal positions in the aftermath of the Global Financial Crisis, which sheds light on the importance of coordinating fiscal policy and monetary policy to achieve price stability. This thesis, therefore, aims to investigate the effects of fiscal policy on the different transmission channels of monetary policy, which ultimately results in high inflation.

The thesis examines the fiscal policy transmission from the trading partners to Vietnam - a small economy, still heavily dependent on agricultural advantages and less resistant to external shocks. The thesis will in turn explore whether or not the spread of fiscal policy from countries with trade relations to Vietnam and the change in the spread characteristics from different countries to the Vietnamese economy.
