Owing to fluctuations in the financial markets from time to time, the rate [lambda] of Poisson process and jump sequence {Vi} in the Merton's normal jump-diffusion model cannot be expected in a precise sense. Therefore, the fuzzy set theory proposed by Zadeh [Zadeh, L.A., 1965. Fuzzy sets....

Our assessment of the competitiveness of the Hong Kong economy from various perspectives indicates that the overall competitiveness of Hong Kong economy has been improving during the past several years. However, from a longer term historical perspective, there are still a number of areas in...

The periodical fluctuation phenomenon appears in coal mine and other fields of government safety supervision. The paper provides a theoretical explanation by building an evolutionary game model between coal mine industry and governmental supervision institutions. Moreover, the paper provides a...

We use extreme value theory (EVT) to develop insights about price theory. Our analysis reveals "detail-independent" equilibrium properties that characterize a large family of models. We derive a formula relating equilibrium prices to the level of competition. When the number of firms is large,...

This is the date set used for Deininger, Klaus & Squire, Lyn, 1996. "A New Data Set Measuring Income Inequality," World Bank Economic Review, World Bank Group, vol. 10(3), pages 565-91, September. This data set is the product of a joint effort of Hongyi Li, Lyn Squire, Tao Zhang, and Heng-fu Zou...

In this paper, we have obtained closed-form solutions in Cass-Koopmans growth models with heterogeneous agents. The relationship between the form of production function and the dynamics of income distribution is made explicit. We then use this relationship to determine what production structure...

This paper shows that top management structures in large US firms radically changed since the mid-1980s. While the number of managers reporting directly to the CEO doubled, the growth was driven primarily by functional managers rather than general managers. Using panel data on senior management...

[eng] Estimation of Short Run and Long Run Elasticities of Energy Demand from Panel Data Using Shrinkage . Estimators by Hongyi Li, G.S. Maddala and Robert P. Trost . In the analysis of panel data, there are, broadly speaking, three approaches: to present separate estimates of the parameters in...

This paper investigates how to coordinate a one-manufacturer–two-retailers supply chain with demand disruptions by revenue-sharing contracts. Firstly, we study the coordination of the supply chain without demand disruptions and give the feasible revenue-sharing contracts, which assure the...

Following the framework of Klein [1996. Journal of Banking and Finance 20, 1211–1229], this paper presents an improved method of pricing vulnerable options under jump diffusion assumptions about the underlying stock prices and firm values which are appropriate in many business situations. In...
