A neo-Schumpeterian perspective on the analytical macroeconomic framework : the expanded reproduction system
(2015) Jun, Bogang; Kim, Tai-Yoo
This study aims to introduce a new analytical macroeconomic framework, the expanded reproduction system, that combines the accumulated wisdom of several contemporary economic models while also compensating for their shortcomings. This new framework may be used to study macroeconomic phenomena from both the supply and demand side over a number of different time intervals. Furthermore, as we account for both new product and productivity innovations, we are able to account for both qualitative and quantitative developments within the economy.
Has the German reunification strengthened Germany’s national innovation system? : Triple Helix dynamics of Germany’s innovation system
(2016) Jun, Bogang; Yi, Seung-Kyu
This paper investigates whether the German reunification strengthened the country’s national innovation system, using the Triple Helix model. In particular, it assesses the various dimensions of the innovation system by analyzing co-authorship networks from 1973 to 2014. Despite the series of policies promoting collaboration between the two regions and the rise in the number of regional collaborations and in the number of papers, the results show that the national innovation system of Germany has worsened since the reunification in 1990, and the role of government is critical in encouraging collaboration. Finally, this paper uses survey data on the type of Triple Helix configuration that actually occurred in East Germany as a robustness check.
Non-financial hurdles for human capital accumulation : landownership in Korea under Japanese rule
(2014) Kim, Tai-Yoo; Jun, Bogang
This paper suggests that inequality in landownership is a nonfinancial hurdle for human capital accumulation. It is the first to present evidence that inequality in landownership had an adverse effect on the level of public education in the Korean colonial period. Using a fixed effects model, the present research exploits variations in inequality in land concentration across regions in Korea and accounts for the unobserved heterogeneity across these regions. The analysis establishes a highly significant adverse effect of Land inequality on education in the Korean colonial period.
The co-evolution of innovation networks : collaboration between West and East Germany from 1972 to 2014
(2016) Mueller, Matthias; Buchmann, Tobias; Yi, Seung-Kyu; Jun, Bogang
This paper describes the co-evolution of East and West German innovation networks after the German reunification in 1990 by analyzing publication data from 1972 to 2014. This study uses the following four benchmark models to interpret and classify German innovation networks: the random graph model, the small-world model, the Barabási–Albert model, and the evolutionary model. By comparing the network characteristics of empirical networks with the characteristics of these four benchmark models, we can increase our understanding of the particularities of German innovation networks, such as development over time as well as structural changes (i.e., new nodes or increasing/decreasing network density). We first confirm that a structural change in East–West networks occurred in the early 2000s in terms of the number of link between the two. Second, we show that regions with few collaborators dominated the properties of German innovation networks. Lastly, the change in network cliquishness, which reflects the tendency to build cohesive subgroups, and path length, which is a strong indicator of the speed of knowledge transfer in a network, compared with the four benchmark models show that East and West German regions tended to connect to new regions located in their surroundings, instead of entering distant regions. Our findings support the German federal government’s continuous efforts to build networks between East and West German regions.
The legacy of Friedrich List : the expansive reproduction system and the Korean history of industrialization
(2016) Jun, Bogang; Gerybadze, Alexander; Kim, Tai-Yoo
This study revisits the theory of Friedrich List from a more comprehensive and modernized perspective and applies it to the Korean history of industrialization. Although List is well known as the scholar who insisted on the protection of infant industry, his argument on protectionism is a part of the broader picture depicted in his book The National System of Political Economy (1841). This study follows his theoretical legacy in various fields of study. Although we can find his theoretical influence in several fields of research such as the national innovation system, concept of national competitiveness, and theory of developmental state, these studies fail to embrace all the arguments of List. Additionally, theses models focus more heavily on the explanation of historical and regional development phenomena without providing general principles of economic development behind the phenomena. This study therefore aims to suggest the expansive reproduction system as a generalized and modernized version of List’s theory and to show its example by using the Korean history of industrialization. Consequently, we argue that the economic development of Korea has been achieved by putting the theory of List into practice.
The tradeoff between fertility and education : evidence from the Korean development path
(2014) Lee, Joongho; Jun, Bogang
Unified Growth Theory suggests the demographic transition and the associated rise in human capital formation were critical forces in the transition from Malthusian stagnation to modern economic growth. This paper provides empirical evidence in support of this hypothesis based on the Korean industrialization in the late 20th century. Using a fixed effects model and a fixed effect two-stage least squares model, this study exploits variations in fertility and in human capital formation across regions in Korea over the period 1970 to 2010. This analysis finds a virtuous cycle, where technological progress increased the demand for human capital, leading to an increase in the level of education and, in turn, to a demographic transition. This establishes the existence of a quantity–quality tradeoff on the Korean development path.
