Since the breakdown of the Bretton Woods System, exchange arrangements of countries have become flexible. Several attempts have been made to determine whether the theories of optimum currency areas adequately explain the choice of an exchange rate system. In this paper, the optimum currency area is retested. Using cross-section data, a regression analysis of the choice of an exchange rate syste...

Nowadays, purchasing decisions are increasingly considering both tangible and intangible factors that in supplier selection. If suppliers have capacity or other different constraints, the problem is to identity the potential suppliers and to allocate the optimal order quantity among the selected suppliers. In this paper an integrated model of analytic hierarchy process (AHP) and preemptive goal...

The real options approach is used to explain discounted utility anomalies as artifacts of the optimizing behavior of an individual with standard preferences, who perceives the utility from consumption in the future as uncertain. For this individual, waiting is valuable because uncertainty is revealed over time. The fair price (or compensation) that the individual agrees to pay (or accept) today...

This paper proposes a Stochastic Chance-Constrained Programming Model (SCCPM) for the supplier selection problem to select best suppliers offering incremental volume discounts in a conflicting multi-objective scenario and under the event of uncertainty. A Fast Non-dominated Sorting Genetic Algorithm (NSGA-II), a variant of GA, adept at solving Multi Objective Optimization, is used to obtain the...

The Russian economy has encountered substantial exchange rate volatility due to many endogenous and exogenous shocks, including the adoption of different systems, global financial crisis, sanctions, COVID pandemic. long experience with a managed floating system, which motivates us investigate response domestic economic policy uncertainty, incorporating oil prices trade volume under circumstance...

This paper proposes a chance-constrained multi-objective goal programming model for supplier selection problem with uncertain factors. Considering uncertain factors of demand, capacity and lead time and several objectives, the proposed approach provides chance constraints leading to a order allocation decision-making result. The decision keeps the confidence and risk of constraints to a certain...
