Real Business Cycle (RBC) theory together with its applications is one of the most important studies in macroeconomics. Recently, Finn Kydland and Edward Prescott received Nobel Memorial Prize in Economics. RBC is deeply affected by New Keynesian School (NKS). For example, Solow model emphasizes using CES of production function in RBC. Recently, New Keynesian Economics gives microeconomic foundations of incomplete competition, and explains macroeconomic fluctuations by prices and wages sticky. RBC and NKE were generalized into a new brake through model called DSGE. DSGE combines RBC and NKE to be a microeconomics foundation model. They consider household and firm optimal choice and integrate real and nominal shocks to let theory in macroeconomic to be close to the real world situation. This paper adopts DSGE model in Schmidt and Zimmermann (2005) into Taiwan. From 1981 to 2006, we discuss fluctuaction of macroeconomic variables in a small open economy by national oil price shocks between effect of oil price fluctutaion relationship. There are two main contributions: First, to review and put related Taiwan¡¦s literatures together which supply important calibration values. These sources provide prior information to finish foundations of this thesis. Second, this is the first thesis based on importance of price of imported oil in Taiwan. We split time-series data from 1981 to 1997 and 1998 to 2006. In the period from 1981 to 1997 the oil price shocks can explain 47% of the Taiwan business cycle fluctuations. In the second period, from 1998 to 2006, the oil price shocks can explain 69% of the Taiwan business cycle fluctuations. The main result is that the oil price shocks have more significant influence on the business cycle in Taiwan.

The primary purpose of this study is to explore whether changes in oil price are exogenous for small open economy and the significance of the financial variables in accordance with empirical results to discuss the role of monetary policies and implications. Considering the factors of monetary policy of the central banks with respect to the SVAR model, that tries to determine whether oil price shocks have disparaged effects on two small market economies, Taiwan and Korea, and trying to compare the difference and effects of their respective policies. In this paper, the empirical analysis, we found that the oil price shocks is a direct result of a major factor in decline in output, and while the impact of monetary policy effects on output is vague that coincide with Kim and Roubini (2000). In addition, Bernanke et al. (1997) analysis of the central bank encounter with the rise in oil prices in response to raise interest rates, the empirical results in this article: (1) policy implementation between the two countries have a significant impact on oil prices will be affected by the increase in oil prices which led to the implementation of central bank tightening of monetary policy , (2) central bank policy changes on behalf of the discount rate shocks, their impact on the real impact of the output is limited, (3) found that the central bank monetary policy to curb the effect of smaller price increases.

The thesis is focused on verifying the pro-cyclical relationship of sales of new passenger cars in the Czech Republic and Slovakia and the subsequent evaluation of the impact of macroeconomic variables in the period from the first quarter of 2005 to the third quarter of 2015. In total, there are four different models estimated of multiple linear regressions of car sales, where for the Czech R. the estimation of different sectors of households and firms is available as well. By comparing the Czech R. and Slovakia regarding aggregate sales, fuel prices and gross domestic products are especially crucial and the pro-cyclical relationship is successfully verified. The economic crisis at the turn of 2008-2009 hit especially Slovakia, while the effect in the Czech R. was offset by a positive shock to fuel prices. For the model of households the procyclical relationship is denied unlike from the model of firms, shock to GDP therefore only deviate sales to firms. For Czech R. is also confirmed a significant relationship of the sales with interest rate or population growth.

This study examines the dynamic relationship between changes in oil prices and the economic policy uncertainty index for a sample of both net oil-exporting and net oil-importing countries over the period 1997:01-2013:06. To achieve that, we extend the Diebold and Yilmaz (2009, 2012) dynamic spillover index using structural decomposition. The results reveal that economic policy uncertainty (oil price shocks) responds negatively to aggregate demand oil price shocks (economic policy uncertainty shocks). Furthermore, during the Great Recession of 2007-2009, total spillovers increase considerably, reaching unprecedented heights. Moreover, in net terms, economic policy uncertainty becomes the dominant transmitter of shocks between 1997 and 2009, while in the post-2009 period there is a significant role for supply-side and oil specific demand shocks, as net transmitters of spillover effects. These results are important for policy makers, as well as, investors interested in the oil market. (authors' abstract) / Series: Department of Economics Working Paper Series
