Generally speaking, business cycle could be discussed as a short-term fluctuation of business cycle and long-term economic growth. In this research, we will confer what impact factors might have affected the business cycle of correlations (BCCs) across countries in a period of short time. Many empirical analysis have pointed out the temporary factors to the business cycle mainly come from the transferred factors of economic aspect. This is called ¡§Transmission Mechanisms.¡¨ What is ¡§Transmission Mechanisms?¡¨ Economists often try to substitute it in good markets, financial markets, and the coordination of monetary policies. However, in this duration of the empirical analysis, using only these proxy variables to explain BCCs between two countries seems too limited. According to this situation, we believe if the BCCs can be explained by using proxy factors of non-economic variable, the result can be utilized by making up the defect. We attempt to find new factors in political approach and combine with the ¡§Transmission Mechanisms¡¨ that we have introduced earlier. After that, we expect to comprehend the BCCs among G7 countries from the inputs of the two completed different variables. To analyze further economic implication in our research, five conclusions have been summarized below: Firstly, increasing bilateral trade has significantly provided positive effect to BCCs among G7 countries from 1980 to 2002. Because the empirical result of Single Country is insignificant, we then use a two-stage method. First, we estimate ¡§Trade¡¨ from endogenous variable to exogenous one. Secondly, we use Panel method to expand its matrix. Finally, we improve the empirical estimators of insignificant statistics before. In other words, the important variables of the correlation of bilateral trade are whether or not the two countries speak the same language; the border problem, and the distance between the two are the same, etc. So, when we talk about the relations between BCCs and good and service markets, we must consider these exogenous factors. Eventually, we will receive more detailed results. Secondly, although to trade in financial markets can increase the BCCs between two countries, the statistic report is insignificant -0.0019 (0.0012). About this empirical result, we can obtain reasonable explanations from the researches (for instance: Imbs, 2004 or Kose et al, 2003), they point out that financial markets are bound excessively by globalization. Therefore, this will aggravatingly make each country to focus on its specialization. Finally, this situation will make the BCCs getting collapsed among these countries. This also explains that the specialization among these countries will reduce the positive effect from the BBCs to financial markets. Thirdly, in this empirical research of Single-Country, we use three proxy estimators of economics to substitute common properties of the monetary policy. At this point, there are no identical correlations of corresponding among other countries except some significantly negative trends shown to the member countries of European Union. According to this situation, we believe it may be the consequence to all the member countries under some ERM restrictions, which is Treaty of Maastricht. Also, because of the rules form this treaty, the monetary policies are getting to be accordant, and the BCCs among the countries will soon appear in obviously positive trend. Fourthly, in the model, the difference of the inflation rate between two countries is not significant with BCCs; therefore, an identical correlation is hardly shown. Moreover, the coefficient symbol is not in our expecting direction, so we think maybe some policies are neglected to the influence of this variable. After all these, we believe if we can control some relative policy effect to inflation rate when discussing the relationship between this variable and the BCCs, we should be able to find out the real effect of this substitutive variable to BCCs Lastly, in the research, the statistics effect of the party variables and business cycle of correlations are very significant. This also indicates the political factor will play an important role for many sources of the fluctuation tread of BCCs. In other words, when we discuss the issue of BCCs if miss the contribution of political factors to the BCCs. Then, this might cause the omitted variable biased, and finally cause the whole computation become inefficient. In addition, we can have further discussion by an input of a factor: to conserve the joint benefit of all the member countries in an economic organization, these countries need to be ruled by the same ideal political party. Otherwise, the institute will never reach its essential result. Combining all the conclusions we have shown above, we can find out the BCCs among G7 countries from 1980-2002. Besides the influence of the ¡§Transmission Mechanisms,¡¨ the result will be varied by the political factors. In conclusion, we need to consider the contribution of the political party variables to the BCCs when talking about this issue, therefore; the original theoretical model can be more persuasive. According to a statistics of IMF, the BCCs among those industrial countries are falling little by little in recent years. Therefore, consolidating trade cooperation is essential for what we believe to improve the BCCs among G7. At the same time, pass through a strong integrate monetary policy can move forward all the incumbent parties from all the countries to agree among themselves, and even reach more substantial effect. From the example like this, we might find evidence from BCCs issues by discussing the integration process in European Monetary Union.

In the first essay, Distortions in the Neoclassical Growth Model: A Cross Country Analysis, I show that shocks that express themselves as total factor productivity and labor income taxes are comparably more synchronized than shocks that resemble distortions to the ability of allocating resources across time and states of the world. These two shocks are also the most important to model. Lastly, I document the importance of international channels of transmission for the shocks, given that these are spatially correlated and that international trade variables, such as trade openness correlate particularly well with them. The second essay is called Monetary Business Cycle Accounting for Sweden. Given that the analysis is focused in one country, I can extend the prototype economy to include a nominal interest rate setting rule and government bonds. As in the previous essay, distortions to the labor-leisure condition and total factor productivity are the most relevant margins to be modeled, now joined by deviations from the nominal interest rate setting rule. Also, distortions do not share a structural break during the Great Recession, but they do during the 1990’s.  Researchers aiming to model Swedish business cycles must take into account the structural changes the Swedish economy went through in the 1990’s, though not so during the last recession. The third essay, Consumer Confidence and Consumption Spending: Evidence for the United States and the Euro Area, we show that, the consumer confidence index can be in certain circumstances a good predictor of consumption. In particular, out-of-sample evidence shows that the contribution of confidence in explaining consumption expenditures increases when household survey indicators feature large changes, so that confidence indicators can have some increasing predictive power during such episodes. Moreover, there is some evidence of a confidence channel in the international transmission of shocks, as U.S. confidence indices help predicting consumer sentiment in the euro area.

The financial state of the most companies was significantly challenged by the last decade. Thus, financial managers must be aware of all factors that can contribute to the firm`s profitability in order to fight unstable economical environment. Working capital management`s effect on profitability has been raised recently and its importance is already known. This thesis aims to dig deeper into the relationship between working capital management and firm`s profitability across different sectors and different time periods. The subject for the empirical analysis are 908 UK manufacturing and 315 construction firms during the period of 2006-2013. The results indicate about the strong negative relationship between working capital, measured as cash conversion cycle (CCC) and gross operating profitability. Thus, it is an indicator that working capital and its characteristics must be included in the firm`s financial planning.

There appears to be a vacillation from the original intent of the Employment Act of 1946. It was originally intended to serve as a tool whereby the smoothing and the easing of cyclical fluctuations of the business cycle could be facilitated. It now seems as though this tool has become one which is being used to correct those structural weaknesses which exist in the economy.

This paper aims to evaluate merits of the Austrian business cycle theory in explaining the 2001-2009 business cycle in the US economy. The theory postulates that a monetary shock upsets equilibrium in the market for loanable funds and adversely influences coordination mechanisms of the economy. The structure of relative prices is distorted and resources are misallocated as a result. The economy follows an unsustainable investment trajectory inconsistent with the amount of available resources and with the consumer preferences. When the inconsistencies are revealed, some of the investments are liquidated and costly correction follows. After providing exposition of the theory and description of the US economy in 2001-2009, the theory is confronted with the data. Although some deviations are conceded, mainly in development of the labor market, analysis presented in the paper supports the Austrian business cycle theory as a solid theoretical tool for explanation of the economic development throughout the examined period. The theory exhibits its main strengths in accounting for development of relative prices and linking them to conditions in the market for loanable funds.
