A Dmp Model of Intercity Trade
The paper presents a model of an economy whose urban structure consists of cities of different types. All cities produce a non-tradeable final good using both types of tradeable intermediate varieties. Each city has an internal spatial structure: individuals commute to the CBD in order to work, when employed, and to seek jobs, when unemployed. Hiring by each intermediate producing firm is subje...
متن کاملthe algorithm for solving the inverse numerical range problem
برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولSolving Polynomial System Efficiently and Accurately
We consider the problem of finding the isolated common roots of a set of polynomial functions defining a zero-dimensional ideal I in a ring R of polynomials over C. Normal form algorithms provide an algebraic approach to solve this problem. We use new characterizations of normal forms and describe accurate and efficient constructions that allow us to compute the algebra structure of R/I, and he...
متن کاملSolving Triangular Systems More Accurately and Efficiently
We present a new algorithm that solves linear triangular systems accurately and efficiently. By accurately, we mean that this algorithm should yield a solution as accurate as the one computed in twice the working precision. By efficiently, we mean that its implementation should run faster than the corresponding XBLAS routine with the same output accuracy.
متن کاملMarkets with Search Friction and the DMP Model
What are search frictions? What role do they play in the analysis of markets? Why are they important? These are the questions I will try to answer. Along the way, I will also present a short history of the development of the ideas and relate those developments to the current labor market conditions in Europe and the United States. Perhaps the best way to answer the what question is by example. ...
