The Necessary And Sufficient Condition for Generalized Demixing

Demixing is the problem of identifying multiple structured signals from a superimposed observation. This work analyzes a general framework, based on convex optimization, for solving demixing problems. We present a new solution to determine whether or not a specific convex optimization problem built for generalized demixing is successful. This solution will also bring about the possibility to estimate the probability of success by the approximate kinematic formula

Urbanization Process and Land Use Policy

Within a framewaork of New Economic Geography (NEG) model, this paper intends to show that urbanization rate in an isolated region is determined as a synthetic rerult of rational behavior of each socio-economic agent. In particular, a model is constructed with bearing to explain the urbanization process in Chaina in mind such that the role of government in managing land use allocation is explicitly incorporated and its policy effects can be evaluated. Some results of theoretical analysis and numerical simulation analysis are contrasted with the ones in Fujita and Krugman (1995) incorporating land into an NEG model as well.

Three Essays on Financing Corporate Activities

This study answered how firms finance their corporate activities and how accounting and marketing activities impinge on these financing activities. The findings pointed out some relatively new financing sources other than traditional equity and debt
