The semiconductor industry once again experienced the impact of business cycle on the end of 2008, after the global financial crisis. The investment of equipment is the largest Capex to a semiconductor manufacturer. The equipment firm is at the end of the semiconductor supply chain. The result of Bullwhip Effect makes the impact of business cycle disturbance severer, especially for the back-end supplier which is required to deal with the variant demand, larger customer bases and shorter lead-time, compared to front-end one. The study is to focus on identifying the key success factors of marketing strategy adapting business cycle for a semiconductor equipment firm. Under such environment, it is to understand how the firm should plan the strategy and structure organization to maintain competitive advantage. The manufacturing has been classified into detail process; each one has its own key technology. The industry leadership of each firm is different. To ensure the points well-captured from the line executives, the study adopts the qualitative research methodology through analyzing the industry environment, combining with the relevant literatures, as theoretical basis, and in-deep interview with the marketing and sales executives from the firm of case study. The research reveals five factors as the key success factors of marketing strategy adapting business cycle, including ¡§Segmenting and Differentiating for product development¡¨, ¡§broaden application and extend customer base¡¨, ¡§Overall Operation Capability¡¨, ¡§Sales Network to create partnership with customers¡¨ and ¡§High-quality Pre- and Post-sales support¡¨. The equipment supplier must consider his own advantage and disadvantage, together with realistic situation to keep the leadership or opportunity while understanding the industry trend. Except for riding through the cycle, the firm must keep the sustaining competitive advantage.

This purpose behind this study is to develop a model for forecasting the performance of the Taiwanese economy based on monthly time series data. We first extract the useful factors through factor analysis. Next, we rank the factor scores according to the rules of the trend and interpret the scores as signals to buy or sell appropriately. Our main result is that the Sharpe ratio of out-of-sample back-testing from January 2007 to December 2010 is 0.48, indicating an ability to forecast financial crises. In addition, a Sharpe ratio of 0.95 during the 2008 financial crisis suggests that our model may have been effective in predicting this crisis. Moreover, the macroeconomic factor model can provide better forecasting skills during financial crises. To conclude, this research may be of importance in explaining the relationship between macroeconomic variables and the business cycle, as well as in providing investors with better forecasting signals of the stock market in Taiwan.

This study investigates the effect of National American Customer Satisfaction Index (NACSI) to aggregate consumer spending at different stage of business cycle. In this paper we use the data from The National Bureau of Economic Research (NBER) to determine the recession term ,and we use EGARCH model to catch the asymmetric performance of aggregate consumer spending at different stage of business cycle. In this study we found that when the economic is not in recession period, improvement in aggregate customer satisfaction have a positive impact on future changes in aggregate discretionary consumer spending. The growth in financial obligations ratio have a negative impact on future changes in aggregate discretionary consumer spending at whole business cycle. The growth in financial obligations ratio also attenuate the positive impact from customer satisfaction, and the effect become more strong in recession period.

This thesis aims to understand the sources of business cycles observed in Turkish economy. In particular the thesis investigates the role of investment shocks in explaining fluctuations in output. For this purpose a small open economy DSGE model is estimated on Turkish data for 2002-2011 period by Bayesian methods. Variance decomposition analysis shows that permanent technology shock is the key driving force of business cycles in Turkish economy and the role of investment shock is less spelled.

Abstract Based upon the Nordhaus' model, we can analyze the political business cycle (PBC) of parliamentarian system. This is our point in this paper. Adding an uncertain factor in the Nordhaus' assumptions, we can get unemployment rate of optimal control path by using the dynamic optimal control theory. Comparing these two results, the model of political business cycle of parliamentarian system has higher elective frequency and lower amplitude in the unemployment rate of optimal control path. From the social welfare point of view, which one is better is hard to say? The social welfare is decided by voters' preferences when voters face these two type of PBC. Keywords: Political business cycle (PBC). Parliamentarian system. The optimal

This research attempts to examine whether economic, social, political and institutional factors affected local public expenditures (per capita) in Taiwan. The panel data regression analysis, covering the period from 1989 to 2007, used statistics from the 21 prefectures (5 cities and 16 counties) of Taiwan by applying the median voter model and political business cycle (PBC) model. The findings from the empirical data suggest that the explanatory variable of the median income is significant and has a positive sign as predicted by the priori expectation, with the exception of economic development expenditure. The gap between the median income and average income variables has positive signs in the total, social welfare, police and economic development expenditures. The tax share variable and grant variable on all categories of spending are significant, but the positive sign of the tax share variable contrasts a priori expectations. The population variable and population density variable have negative signs in different expenditures, while the social welfare and the education, science, and culture expenditures have positive signs. Comparing the difference before and after the downsizing of the Taiwan Provincial Government, the significance of the latter is higher than the former, and the effects of various variables differ. The results of this research also indicated that the variables of the pre-election year, election year and post-election year demonstrated statistical significance with varying directional tendencies, and that the results are inconsistent with the traditional hypothesis of the election cycle. The incumbent magistrates or mayors, regardless of whether they do or do not intend on re-election, exhibit no significant influence on most expenditures, and thus this does not agree with a priori expectations. The administrative satisfactions of incumbent magistrates or mayors have statistically significant influence on the expenditures and deficits. Generally, the Pan-KMT incumbent magistrates or mayors have more motives to increase the total and capital expenditures and deficits than the Pan-DPP. Interestingly, the KMT party, which held the majority of seats in the county council, has a positive sign and statistically significant influence on the expenditure of grants to townships. The evidence has demonstrated that a unified government or divided government (horizontal type or vertical type) has no significant influence on most of the expenditure forms, although a negative sign on social welfare expenditure is evident in 21 counties and cities. The lagged deficit is significant with a positive sign, which implies that the insufficiency of local accountability and deficits are becoming a long-term problem. When comparing the power of the median voter model and political business cycle model in explaining the local public expenditure, a non-nested test was implemented. No model was found to hold an advantage over another model. In brief, the current research indicates that the factors of the majority voters' demands, elections and parties indeed have different influences on various expenditure forms in Taiwan.

<p>The  Austrian  Business  Cycle  Theory  (ABC)  provides  a  qualitative  explanation  of  why economies go through ups and downs in terms of national income, production output and labor employment. The theory states that interest and money supply policy distort the time preferences of economic agents. If the monetary authority reduces the interest rate through artificial credit expansion the new economic conditions induce both increased production and consumption. The  framework of  the Austrian  theory depends on  savings  to  fuel  investments, i.e. reduced consumption in order to create increased future consumption. Artificially  induced  expansions  create  a wedge between  these producer  and  consumer preferences, and prolonging of the process widens the gap between the economic state and the free market  equilibrium which  is  long-term  sustainable. When  the  financial  system  eventually is unable to maintain inflation of credit to uphold the economy, there will be abandonment of capital investments, resulting in an unavoidable recession. The purpose of this thesis is to analyze the theory from a short run perspective, using data from  the United Kingdom  economy. The  theory has previously primarily been  tested  in long run perspectives and mainly on the American economy. To achieve the noted a model was constructed based on the description of the theory by economists Hayek and Garrison, members of the Austrian school of economics. To empirically model the ABC theory the ratio between consumption and investment, the intertemporal  resource allocation, was  calculated and used as a dependent variable  in  regressions with money aggregates, credit and interest rate gap as independent variables. The empirical findings give some support to the theory, with a number of those findings directly in favor of the theory. Credit was shown to better explain changes in the C/I ratio than money aggregates, indicating that credit is more directly suited for investments. The coefficient for the interest rate gap, the difference between the natural interest rate and the market interest rate, showed strong significance. Overall differences between economic expansions and recessions were found statistically significant, which lends support to the model.</p>

This dissertation consists of three essays on topics in macroeconomics. In the first chapter, I construct a macroeconomic model with a heterogeneous banking sector and an interbank lending market. Banks differ in their ability to transform deposits from households into loans to firms. Bank size differences emerge endogenously in the model, and in steady state, the induced bank size distribution matches two stylized facts in the data: bigger banks borrow more on the interbank lending market than smaller banks, and bigger banks are more leveraged than smaller banks. I use the model to evaluate the impact of increasing concentration in US banking on the severity of potential downturns. I find that if the banking sector in 2007 was only as concentrated as it was in 1992, GDP during the Great Recession would have declined by 40% less it did, and would have recovered twice as fast. In the second chapter, my co-author and I investigate the impact of firm capacity constraints on aggregate production and productivity when the economy is driven by aggregate and idiosyncratic demand shocks. We are motivated by three observed regularities in US GDP: business cycles are asymmetric, in that large absolute changes in output are more likely to be negative than positive; capacity and capital utilization are procyclical, and increase the procyclicality of measured productivity; the dispersion of firm productivity increases in recessions. We devise a model of demand shocks and endogenous capacity constraints that is qualitatively consistent with these observations. We then calibrate the model to aggregate utilization data using standard Bayesian techniques. Quantitatively, we find that the calibrated model also exhibits significant asymmetry in output, on the order of the regularities observed in GDP. The third chapter explores the role of distance in equilibrium selection. I consider a model economy with multiple steady state equilibria where a high productivity and a low productivity technology are available for use in production. The high productivity technology requires a fixed set up cost for production. Sectors are linked by localized production complementarities. I consider selection under a learning rule in which agents imitate their most successful neighbor. As distance between neighbors decreases, the possible profits from industrialization increase, and the likelihood that the learning rule process converges to a steady state matching the H equilibrium increases. The result suggests that, in the presence of localized technology spillovers, there may be important gains to economic growth from infrastructure development. / text

This dissertation consists of three essays on income risk and aggregate demand over the business cycle, each addressing an aspect of the Great Recession. The first chapter reframes the standard liquidity trap model to illustrate the costly feedback loop between idiosyncratic risk and aggregate demand. I first show that a liquidity trap can result from excess demand for precautionary savings in times of high uncertainty. Second, I show that the output and welfare costs of the ensuing recession depend crucially on how the drop in demand for output is translated into a reduction in demand for labor. Increased unemployment risk compounds the original rise in idiosyncratic productivity risk and reinforces precautionary motives, deepening the recession. Third, I show that increasing social insurance can raise output and welfare at the zero bound. I decompose these effects to distinguish the component unique to the liquidity trap environment and show that social insurance is most effective at the zero bound when it targets the type of idiosyncratic risk households face, which in turns depends on the labor market adjustment mechanism. The second paper offers a novel model of the connection between the consumer credit and home mortgage markets through an individual’s credit history. This paper introduces a novel justification for the home mortgage interest deduction. In an economy with both housing assets and consumer credit, the mortgage interest deduction is modeled as a subsidy for the accumulation of collateralizable assets by households who have maintained good credit. As such, the subsidy loosens participation constraints and facilitates risk-sharing. Empirical evidence and a calibration exercise reveal that the subsidy has a sizable impact on the availability of credit. The third paper assesses the role of policy uncertainty in the Great Recession. The Great Recession features substantial geographic variation in employment losses, a fact that is often presented as a challenge to uncertainty-based models of the downturn. In this paper we show that there is a substantial correlation between the distribution of employment losses and the increases in local measures of both economic and policy uncertainty. This relationship is robust across a wide range of measures. / Economics
