Title of Dissertation: national renewable energy policy

Hypothesized causal chain of policy change. 
Two countries are selected as cases: the United States and South Korea. It is hard 
for a single case study to be compelling because each country exists in its unique 
contexts. Therefore, two-case studies are chosen for this research. The pool of cases was 
limited to the Organization for Economic Co-operation and Development (OECD) 
member countries to control the effects of the lack of institutional infrastructure. Among 
these 33 countries, six countries that have multinational solar manufacturers were

selected (Table 5). Having multinational solar manufacturers means that the countries 
have developed solar PV industry. Since the independent variable of this research is the 
growth of solar PV industry, the cases were limited in the countries with developed solar 
PV industry. Those countries were divided into two groups: the countries with a big 
domestic market and the countries with a small domestic market. The U.S., Japan, and 
Germany are in the big domestic market group since each country is one of the top 10 
countries in terms of solar capacity.

South Korea, Norway, and Canada are in the small 
domestic market group. One country was selected from each group. The size of domestic 
market was used as a criterion since it is expected to influence the degree of effect of 
globalization of solar PV industry. For the country with a small domestic market, 
globalization of the industry would more significantly influence the domestic industry 
and policies compared to the country with a large domestic market. Finally, the U.S. and 
South Korea were selected as cases considering the feasibility of data collection.
