The relationship between financial development and economic growth has been the subject of considerable debate in development and growth literature. Therefore this chapter provides evidence on the role of financial development in accounting for economic growth in 23 OECD countries (Italy, Japan, Luxemburg, Holland, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, England, USA, Australia, Austria, Belgium, Canada, Denmark, Finland, Turkey, France, Germany, Greece, Iceland) via panel data analysis using the annual data for the period 1980-2012. The authors find a positive relationship between financial development and economic growth for all countries. Also this result means that financial development leads economic growth in these countries. So the results may help policymakers formulate effective financial sector policies as a tool to promote economic growth.

IntroductionHere we present our clinical experience in a case of esophagus perforation due to the swallowing of a bone piece causing acute angina pectoris and leading to misdiagnosis of acute coronary syndrome.Case presentationA 73-year-old Caucasian man underwent urgent coronary angiography with possible diagnosis of acute coronary syndrome. His coronary arteries were found to be normal. A computed tomography examination revealed esophagus perforation by a foreign body (a piece of bone), and he underwent urgent left thoracotomy and the foreign body was removed.ConclusionsSometimes, even a piece of bone within a meal can lead to esophagus perforation, and injure the pericardium and myocardium. The symptoms of esophagus perforation may be confused with acute coronary syndrome due to their similarities and lack of knowledge about the detailed clinical history as shown in our case. Thus, careful consideration of detailed clinical history as well as choosing an appropriate medical imaging modality, such as computed tomography, should always be kept in mind in order to promptly diagnose and start early treatment to reduce mortality.

In this chapter, the authors investigate the causality relationship between the inflows of foreign direct investment (FDI) and economic growth as measured by Real Gross Domestic Product (GDP) per capita in Turkey during the period 1974-2012 by using the Granger causality tests. The causality test indicates that economic growth Granger-causes FDI. This means that there is bidirectional causality from Reel GDP to FDI in Turkey. So the author results support “the growth – driven FDI hypothesis”. This demonstrates that in the related time in Turkey, more direct foreign investment entered the economy together with an increase in economic growth.
