The self-employed constitute a large proportion of the workforce in developing countries and the sector is growing. Different accounts exist as to the causes of this development, with pull factors such as high returns to capital contrasted with push factors such as barriers to more desirable salaried jobs.

This paper studies the impact of credit rating agency (CRA) announcements on the value of the Euro and the yields of French, Italian, German and Spanish long-term sovereign bonds during the culmination of the Eurozone debt crisis in 2011-2012.

The manual also includes the most important references from the literature as well as the wording of all of the items and answer options in the scales ...
