This paper aims at investigating the dynamics between aging population and local finance. In recent years, the aging rate has been accelerating the pace. The trend implies that Korea is moving towards the aging society, presumably, with unprecedented speed in the world. Aging society's biggest problems are centered around the explosive growth of the financial needs. In particular, these problems are apt to appear more seriously in local governments, as most of them are confronted with high level of aging population and poor financial bases. Firstly, it analyzes how the population structure in the local government impacts local finance, income and expenditure. Based upon in-depth literature reviews, this study examines variables related to aging population and local fiance. Secondly, it focuses on a series of positive and negative feedback loops which would reveal the essence of the mutual interaction structure between aging population and local governments' fiscal behaviors.

A good business performance measurement system is an effective tool io sustained growth in profits. Although interest in creating performance measurement models is widespread, a well-designed system is rare. To be successful in today's competitive environment, a performance measurement system should incorporate strategic success factors and contain financial and non-financial measuring index to carry out strategic management. In the 1990s, Kaplan & Norton introduced a concept called the Balanced Scorecard. The Balanced Scorecard supplements traditional financial measures with criteria that measured performance from three additional perspectives - those perspectives of customers, internal business processes, and learning and growth. This paper presents five measuring index criteria for each perspective. To calculate the relative priority for These measuring index, we investigate weights investigated by interviews with management consultant. Then, AHP method is employed for calculating priority weight. Our evaluation model may be referred to as the Balanced Analytic Hierarchical Performance Model(BAHPM) in the sense that the analytic hierarchical scheme, along with the AHP, is applied. The BAHPM is the first kind of analytical model to cover a wide variety of measures. In comparison with previous evaluation models, our model shows strengths in structural flexibility, ease of incorporating feedback, group evaluation capacity, participation promotion, sensitivity analysis, and computational simplicity. A prototype based on the BAHPM can be applied to various industry sectors.

This paper investigates the impact and behavior of foreign equity investment in Asian emerging economies during the 2007-2008 and the 2010-2012 global financial crises in terms of volatility and return. The empirical results indicate that foreign investors show positive feedback trading behavior in the sample countries. We find evidence that foreign investors' net selling behavior significantly increases market volatility in most countries.

In This paper we study the interrelationship between firm's strategies, MCS (Management Control System), and financial and non-financial performance. And also the objective of this study is to advance the understanding of mediating effect of management accountant on these relationships. This is a suggestion on the study of contemporary settings as little contingency work was carried out on balanced scorecard, target costing, life cycle costing, which come under the broad array of non-financial performance indicators. The result of this study finds that the higher the unpredictability of the business, the more necessary it is to secure a controller within the business. This strongly implies that the controllers must be the main subject of continued growth as they perform an active role within the overall management control process of performance indicator development, performance measurement, feedback, and reward, starting from the very beginning stages of the strategy development within the business.

In this study, I examined capital market shock reaction effects of 29 OECD countries with the past 24 years sample period consisting of daily stock market return using T-GARCH model focused on volatility feedback hypothesis. US daily stock market return is used as a unique independent variable in this model in consideration of its characteristics of biggest market share and as an origin country of Global Financial Crisis. As a result, France, Finland, and Mexico in order are shown to be the strongest countries in the aspect of return spillovers from US. Canada, Mexico, and France are shown to be the highest countries in the aspect of explanatory power of model. The degrees of shock reaction are proved to be higher in order in Germany, Chile, Switzerland, and Denmark and those of downside shock reaction are seen higher in order in Greece, Great Britain, Australia, and Japan. Canada and Mexico belonging to NAFTA are shown to be higher in the return spillover from US and in the model explanatory power, but they are shown to be lower in the impact of shock reaction, suggesting that regional distance effect or gravity theory cannot be applied to financial spillovers any longer. In the analysis of subsample period of Global Financial Crisis, north American three countries do not show any consistent results as in the full sample period but shock reaction in the European countries are shown to record stronger, suggesting that shocks from US in the Crisis Times are transferred mainly to European region.

In this paper, the simulation model of house price is presented on the basis of pricing mechanism between the demand and the supply of apartments in seoul. The algorithm of house price simulation model for calculating the rate of price over time includes feedback control theory. The feedback control theory consists of stock variable, flow variable, auxiliary variable and constant variable. We suggest that the future price of apartment is simulated using mutual interaction variables which are demand, supply, price and parameters among them. In this paper we considers three items which include the behavior of apartment price index, the size of demand and supply, and the forecasting of the apartment price in the future economic scenarios. The proposed price simulation model could be used in public needs for developing a house price regulation policy using financial and non-financial aids. And the quantitative simulation model is to be applied in practice with more specific real data and Powersim Software modeling tool.

We focus on the relationship between the wage and the productivity in the Korean manufacturing industry over the period from the 1971 year to the 2000 year by using the Geweke's linear feedback method and the impulse response method. And we divide the whole period into the 1971-before the financial crisis and the 1971-2000 including the after the financial crisis to study the change of the relationship between the wage and the productivity after the financial crisis. The results are the followings; The productivity has the large influence on the wage positively, so that the improvement of the productivity boosts the wage and the vice versa in the before financial crisis period. It means that both the conventional wage setting theory and the alternative wage theory(efficiency wage and union theory) exist in the manufacturing industry. However, there exist only the conventional wage setting theory in the whole period.

본 논문은 주가(株價)의 변동성검증모형(變動性檢證模型)을 한국주식시장(韓國株式市場)에 적용하여 시장의 효율성을(效率性) 검증하였다. 1975년부터 1990년까지 의 17년 기간중 Shiller[81a], Mankiw-Romer-Shapiro[85], West[88b]의 모형을 이용하여 검증한 결과, 높은 수준의 과잉변동성(過剩變動性)이 발견되었다. 그러나 이러한 주가의 과잉 변동성을 시장이 비효율적이라는 증거로 간주하기는 어렵다. 왜냐하면 이들 모형의 가정 중의 하나인 할인율이 일정하다는 가정을 완화시켜 다시 검증한 결과는 오히려 과잉변동성 중에서 많은 부분이 감소하는 것으로 나타났기 때문이다. 다시말해서 주가에 과잉변동성이 존재하는 것은 시장이 비효율적이라기 보다는 기간에 따른 할인율의 변동폭이 큰 데에 원인이 있는 것으로 해석된다. 따라서 할인율(割引率)의 변동원인(變動原因)을 조사하여 주식시장의 효율성을 분석하였다. 주가의 일부는 랜덤웍의 요소에 의해 결정되고, 나머지 일부는 평균회귀(平均回歸) fads(mean reverting fads)에 의해 결정된다고 가정하여 검증한 결과, 후자에 의해 설명된 비율이 매우 높게 나타났다. 즉 한국주식시장에서의 투자자는 교란거래(攪亂去來)(noise trading)나 피드백거래(去來)(feedback trading) 등의 비합리적인 투자행동을 취하고 있으며, 이러한 비합리적인 행동에 의해 주가변동의 $60{\sim}80%$가 설명되는 것으로 보인다.
