Dr. Shinichi Suda
Professor
Department of Economics, Theoretical Economics
Keio University
Dear Professor Suda,
I am writing this letter to explain my motivation behind application for Department of Economics at Keio University, specializing in Theoretical Economics. I have read a number of your published work which I was very intrigued by. I would be extremely grateful if you could kindly give this a consideration.
Abstract
A macroeconometric theory is a set of equations designed to explain an economy or some part of the economy. Here, there are two types of equations: stochastic and identities, and two types of variables: endogenous and exogenous. With the global economy becoming more interdependent and interactive, it is extremely important to understand classical economic theories and also study both exogenous and endogenous factors. Reason being, it is because two companies selling the same product with the same exogenous factors posing obstacles might have very different results because of the endogenous factors.
Argument
It’s not just prices, or supply demand, that can constitute endogenous or exogenous factors in economics. For example, we might have a theory about how economic growth occurs, but we tend to leave out technological change so we can concentrate on other factors such as education or capital formation. Many experts argue that business cycle is merely a result of inevitable exogenous shocks, however, with increasing numbers of natural disasters and international political problems on top of above, that model may not work anymore.
Discussion
Economists have been made aware of certain cyclical characteristics of economic evolution by works of A. Smith (1776), C. Juglar (1862) and many others. Two main theories have attempted over the years, to explain the causes and characteristics of business cycles. Leading theories are known as the real business cycle (RBC) and endogenous business cycle (EBC) theory, both theories seem to have their successes and shortcomings, but the RBC theory is the one that garners consensus in the current economic literature. In most relevant example, China has practiced export focused growth with exports exceeding 40% of GDP and China’s growth policy has driven internal changes and the rapid growth. It is a safe statement to say, it was mostly a result of endogenous factors – government led manufacturing, education and industrialization. A quote from Premier Wen Jiabao is central to this – ‘China’s economy needs to be put on the path of endogenous growth driven by innovation.
Summary
Comparing Japan, US, China economic growth and models verify both models have defaults but does explain contribution of different economic activities. More than ever, the importance of understanding classical theories has been the focal point. I think this is a very important topic with room for further review and I would love to take part in your seminar to conduct research. Thank you very much for taking the time and I look forward to hearing from you soon.
Sincerely Yours,
