This book explores the behaviour of workers? remittances and their impact on financial development in Jordan. It empirically examines the macroeconomic determinants of remittances and investigates the impact of these flows on the level of international reserves holdings and banking sector and stock market development. The methodologies adopted in this study are mainly based on cointegration analysis. The standard cointegration tests are appropriately used to investigate the relationship between remittances and financial development variables for both the banking sector and the stock market. The study also extends cointegration testing, used in determining the effects of remittances.
