In this paper we develop a model to identify real exchange rate and output shocks in the African CFA Franc Zone and in Dollar-pegging Caribbean countries (including members of the East Caribbean Currency Union). These two groups of countries each comprise states using several different local currencies: on the one hand the BCEAOCFA Franc and the BEAC-CFA Franc (both pegged to the Euro), on the ...

In the process industry, both quality and consistency of mid-term planning and short-term scheduling are crucial. We propose a sequential approach consisting in three steps : planning, lot streaming-pegging, and scheduling. This paper focuses on the intermediate problem that consists in cutting up the planned production in several lots (lot streaming) and linking stocks, lots and demands by det...

We consider the repeated assignment problem (RAP), which is a K-fold repetition of the n n linear assignment problem (LAP), with the additional requirement that no assignment can be repeated more than once. In actual applications K is typically much smaller than n. First, we derive upper and lower bounds respectively by a heuristic together with local search, and an efficient method solving the...

A dynamic general equilibrium model of an open economy with staggered wages is constructed. We analyse disinflation through pegging the exchange rate. In accordance with the stylised facts, an initial boom in output can result, depending on the exact level of the peg. The reason is an element of preannouncement in the policy. Disinflation through reducing monetary growth is shown to be equivale...

We introduce a new method of generating random d-regular graphs by repeatedly applying an operation called pegging. The pegging operation is abstracted from a type of basic operation applied in a type of peer-to-peer network called the SWAN network. We prove that for the resulting graphs, the limiting joint distribution of the numbers of short cycles is independent Poisson. We also use coupling...

We consider the multiply constrained assignment problem (MCAP), which is a variation of the linear assignment problem with m additional constraints. First, we derive upper and lower bounds respectively by heuristic and relaxation methods. The latter also implies the Lagrangian relaxation, as well. Next, we introduce the pegging test to MCAP, and further a virtual pegging test to reduce MCAP int...

On February 2, 2002, Lithuania switched its currency anchor from the dollar to the euro. While pegging to the dollar (since April 1994) has proven successful throughout the transition years, the recent decision to peg to the euro was motivated by the increasing trade relations with European economies. This paper does not argue which peg is more appropriate, but it analyses the implications of c...

The knapsack problem (KP) is generalized to the case where items are partially ordered through a set of precedence relations. As in ordinary KPs, each item is associated with profit and weight, the knapsack has a fixed capacity, and the problem is to determine the set of items to be packed in the knapsack. However, each item can be accepted only when all the preceding items have been included i...
