This dissertation addresses the question of whether a monopolistic banking system can lead to a higher steady state level of capital stock. Specifically, this research analyzes the comparative advantage of a monopoly banking system. By doing that, it examines factors that contribute to the promotion of economic growth that come from a concentrated banking system. There is substantial evidence of a positive relationship between financial markets development and long term output growth. Little is known, however, about the role played by the market structure of the banking sector on growth. Moreover, little work, if any, has attempted to analyze how the degree of information externality affects the relative performance of a monopoly and competitive banks. I find that a monopoly banking system might perform better in accumulating capital under both low information externality and high information externality under certain conditions. In addition, this paper shows that developing countries as well as industrial countries may benefit from a concentrated banking system. This result is not found in the existing literature, which has only shown that developing countries may benefit from a monopoly banking system. This result can be interpreted as follows: (i) for the developing countries, as the proportion of high quality firms is relatively low, the loss in output associated with lending capital to lower quality firms is relatively high. In this case, the screening technology has enough value-added to compensate for the loss in output associated with the typical rent extraction activity of the monopolist. (ii) for the industrial countries, a monopoly banking system can overcome inefficiency from free riding problem associated with the information externality. This analysis provides an alternative explanation of the recent deregulation and resulting trends in mergers and acquisitions. This supports governments' policy changes from restricting merger and acquisition activity to allowing or even promoting merger and acquisition activity.

Land subsidence is the gradual settling or sudden sinking of the earth's surface. According to the United States Geological Survey more than 80% of identified subsidence in the United States is a result of groundwater removal. Due to the hydrologic structure and reliance on the Potomac Aquifer, the Southern Chesapeake Bay region of Virginia has suffered from land subsidence since the 1940s. In coastal regions, land subsidence can increase the risk of flooding. This paper presents a mathematical simulation that predicts land subsidence from groundwater pumping. This simulation is used to see how the location of groundwater pumping, as well as the amount of amount of groundwater pumped would differ from two different groundwater pumping policies. The first policy is aimed at limiting land subsidence in the region, while the second policy aims at limiting the damages from land subsidence. These two policies are used to show that a spatially heterogeneous groundwater pumping policy is necessary to minimize the damages from groundwater pumping when land subsidence is present. / Master of Science

The aim of the paper is to investigate what impacts that offline stores will have on their existing competition as retailer firms introduce online stores to compete with rivals.Since online markets become much mature and prevalent recently,retailer firms catch up on the trends and operate online stores in succession.On account of online stores' convenience and vast potential customers,the introduction of online stores must have a great influence on those offline stores that already in the market.Therefore,we analyze the threat that offline stores may confront with lots of perspectives after online stores¡¦ introduction.In addition,under the circumstances that the government imposes sales tax on online stores and offline stores,we compare their after-tax profits with their pre-tax profits while online stores are vulnerable to evade taxation.

The aim of the paper is to investigate how the dual brand of firm decides its optimal allocation of advertising and fundamental strategy of marketing under taking account of markets with multi-consumption externalities. We assume that the market is multi-consumption externalities, and advertising may function as a device to coordinate consumer expectations of the purchasing decisions of other consumers, which is different from the past assumption that consumer type is single and role of advertising in market. Therefore, we reexamine the firm with optimal allocation of advertising. Finally, we show that the firm will adapt different pricing, allocation of advertising and strategy of marketing when facing the different consumer type of combination proportion. If market is dissimilar consumption externalities, above statement will be more significant; On the contrary, if firm facing similar consumption externalities, the optimal is single strategy. In other words, it is independent to consumer's type of combination proportion.

The development of online game in Taiwan is matured and there are also many derived products about it. The total output value of online game industry is still growing at present and the growing rate is at about 8.5% in 2010. There are still many issues worthy to be discussed at the same time. First of all, this research classified the virtual products of online game. Secondly, by analyzing the documents about network externality, the research discussed the effect that those products could influence online game players. Next, with the game model which constructed in the research, the interaction of ¡§paid-player¡¨, ¡§free player¡¨ and ¡§potential player¡¨ were discussed. Finally, the research also analyzed the consumer behavior under different situation of network externality and gave some pricing reference for online game firms. There is the conclusion of the research. To maximum the profit, the online game firms must set higher price for those virtual products which may have negative effects compared to those products which do not have negative effects.
