Analysis Of The Dynamic Behavior Of Office Building Demand And Supply

The 2000’s have claimed as the most fluctuated decade of the Thailand’s real estate economic as well as overall economic. Before 1997, the Capital Companies go abroad to do the road show exhibition and bring back a lot of money to the country. This situation created the economic that the academician called “Bubble Economy” (The economic that speculates the profit is more than the fundamental economic). This Bubble Economy encouraged the Real Estate Market to have highest growth, the land and stock price went up also with the loan interest rate. Thai people expended money more than usual (Thai people expend money around 10% of GDP).

From GDP graph the Bubble Economy can stay for a while. So in the early 1996 the problems of the economic happen, the GDP (Gross Domestic Product) of the country reduce 8.2% because of the principal’s enlargement. Institutional Investor Magazine, Standard & Poor's, Fitch And Moody's reduce the credit rank of Thailand from A to Ba1 that make untruth to the foreign investors. The foreign investors withdraw the capital from Thailand (call the loan back to their country) that effect to the Real Estate Economic. So in the late 1996, the foreign companies didn’t give any loan to Thailand that made the Financial Institution be illiquid. Finally, 1997 the Bubble Economy was broken and the real estate market was dead end. Thailand came to the economic crisis and the economic went to down turn.

In 2000 the government tried to recover the economic by using the public finance strategy to stimulate the economic. The strategy effect on the interest rate of the loan because the government wanted to reduce the interest to activate the economic and reduce the debt responsibility of the government. The interest rate reduce from 15.25 - 15.50% to 11.50 - 12.00% in the end of 1999 and 8.25 - 8.50% and 8.00 - 8.50% in March 2000. Because of the low interest rate of loan the investors tried to invest in the economic again and help the economic went up. When the economic went up the real estate economic was come to the up turn also. But the up turn didn’t take a long time.
In 2006, the Government Housing bank does the research “The model to predict the trend of the real estate in Thailand”. That research indicate that the demand of the people who live in Thailand in any kind and prize of the real estate is 257,130 units in 2003 and has trend to increase to 294,966 in 2007. The supply of the real estate in 2003 is 207,575 units. So in 2000-2005, the real estate market is stay at up turn. Although the demand is going up but the research indicates that after 2006 the real estate market will be saturated because of the problem in the overall economic again due to the oil prize and the political aspects.

From the information we can see that the real estate in 2000’s decade was fluctuated and hardly to predict combined with the rarely system analysis of the overall office market in the past researches. In order to understand and predict the trend of the Real Estate and office market Economic, it is important to develop the factor and economic model of the real estate economic. The model is in the form of a computer simulation which employs the conceptual framework and methodology of “System Dynamics,” developed by Jay W. Forrester in the 1960’s at the Sloan School of management at the Massachusetts Institute of Technology. The model can be used as a forecasting tool in various assumption and factor such as, interest rate, political and macroeconomic.

Mr. Apinun Tantiviriyapan made a research which aim was to solve the problems. His objectives were as follows: (1) to identify the factors that affect the office market; (2) to identify the relationship between those factors and between factors to the office market economic and generate causal loop diagram; and (3) to develop the System Dynamic Model of the Office market Economic

Conclusions

The objective of this modeling exercise was firstly to understand the mechanism of various endogenous and exogenous parameters affecting the change of Gross Domestic Product, Demand of Office Building and Supply of Office Building. Gross Domestic Product, Demand of Office Building, Supply of Office Building, Inflation Rate, Interest Rate, Exchange Rate, Consumption Expenditure, Investment, Net Export, Cost of Material, Cost of Labor and Rental Prize are the primary focused variables within the economic boundary. Secondly, to identify the relationship between those factors and between factors to the office market economic and generate causal loop diagram. From the relation historical data was use to develop relative equation at each main component.

Change Gross Domestic Product is affected by Demand of Office Building, Supply of Office Building and Net Export. Demand of Office Building affects Gross Domestic Product in positive way same as Supply of Office Building and Net Export.

Change in Demand of Office Building is affected by Investment, Consumption Expenditure and Government Spending – Tax. Investment, Consumption Expenditure and Government Spending – Tax have positive relation to Change in Demand of Office Building.

Change in Supply of Office Building is affected by Cost of Labor, Cost of Material and Rental Prize. Rental Prize plays a positive relation to Change in Supply of Office Building but Cost of Labor and Cost of Material play a negative relation to Change in Supply of Office Building.

Economic Condition is measure in term of historical data index. This model structure is based on the literature reviews and the information gathered from the interview conducted with the different parties namely Office Development and Contractor Companies and Academic Institution.

Finally, a dynamic simulation mode was build to represent the perceived mode was built by using the system dynamic methodology. Simulation describes the current behavior and the inferred future. From the result of the simulation, we can develop the pattern of main components and conduct several test to ensure the result.

Several tests such as Unit Consistency Test, Boundary Test and Sensibility test was brought to develop the confidence of the result compare to the real world. The model was applied to the investigation for various components affecting office economic. The simulation trend will give guild line for the investors, developers and contractors to understand the behavior of Office Build Market. This guild line also help in decision making process to make better decision.

His thesis abstract is copied and posted.

ABSTRACT

To understand the office economic behavior, Demand, Supply and Gross Domestic Product are main components that should be defined the trend. There are a lot of factors and variables that affect the trend of main components. This research investigates the impact of various components on the Gross Domestic Produce, Demand of Office Building and Supply of Office Building

The objective of this modeling exercise was firstly to understand the mechanism of various endogenous and exogenous parameters affecting the change of Gross Domestic Product, Demand of Office Building and Supply of Office Building. Secondly, to identify the relationship between those factors and between factors to the office market economic and generate causal loop diagram. Finally, a dynamic simulation mode was build to represent the perceived mode was built by using the system dynamic methodology.

From the result of the simulation, we can develop the pattern of main components that can use as a guild line for the investors, developers and contractors to understand the behavior of Office Building Market. This guideline also helps in decision making process to make better decision.
