In this paper we consider a second order evolution inclusion with a coercive viscosity operator and a multivalued term of subdifferential form. The study is motivated by the dynamic problem of frictional contact between a viscoelastic piezoelectric deformable body and a foundation. The interaction between the body and the foundation is described, due to the skin effects, by a nonmonotone possib...

The H∞ dynamic output feedback controller design of linear neutral delay systems is studied using Lyapunov-Krasovskii stability theory and linear matrix inequality approach. Based on feasibility positive definite solution to the linear matrix inequalities, we first develop a delay-independent stability criterion and a sufficient condition which makes the system asymptotically stable and guarant...

We prove existence, uniqueness, and regularity properties for a solution u of the Bellman-Dirichlet equation of dynamic programming: (1) max {I]u+f i} =0 in (2 i = 1 , 2 u=O on 092, where D and L 2 are two second order, uniformly elliptic operators. The method of proof is to rephrase (1) as a variational inequality for the operator K = L 2 (D)1 in L2(O) and to invoke known existence theorems. F...

|In this paper, we take a new look at the mixed struc-tured singular value problem, a problem nding important applications in robust stability analysis. Several new upper bounds are proposed using a very simple approach which we call the multiplier approach. These new bounds are convex and computable by using linear matrix inequality (LMI) techniques. We show, most importantly, that these upper...

An optimal stopping problem for stochastic differential equations with random coefficients is considered. The dynamic programming principle leads to a Hamiltion–Jacobi–Bellman equation, which, for the current case, is a backward stochastic partial differential variational inequality (BSPDVI, for short) for the value function. Well-posedness of such a BSPDVI is established, and a verification th...

This paper shows that growth and income distribution dynamics are closely linked through occupation, financial intermediation, and education, using the micro data from Thailand. The compositional change of these characteristics accounts for half of the Thai inequality increase and forty percent of the Thai growth and poverty reduction during 1976-1996. Financial deepening and educational expans...

The paper examines the impact of the income distribution in a less-developed country (LDC) on its patterns of trade, through its influence on home market demand patterns. In a learning-by-doing model with nonhomothetic preferences, the authors show that import substitution under low inequality generates more focused learning and enhances trade potential more effectively. In addition, relative w...

This paper presents a contractual framework to investigate the dynamic relation between income inequality and occupational choice in an overlapping generations model. Depending on the natures of equilibrium loan contracts, ex ante expected utilities (or average lifetime incomes) of different occupations in economy are not equal and such inequality persists in the long run. This result is, in co...

Policy, Institutional Factors and Earnings Mobility This paper uses ECHP and OECD data for 14 EU countries to explore the role of labour market factors in explaining cross-national differences in the dynamic structure of earnings: in permanent inequality, transitory inequality and earnings mobility. Based on ECHP, minimum distance estimator is used to decompose earnings inequality into the perm...
