due to increasing number of international tourists and the enhancing role of tourism in economies of countries and competing environment, recognizing determinants in attracting international tourists seems very essential than ever before. public and private sectors need to examine determinants and forecast tourism demand. the primary aim of this study is using econometric techniques to analyzin...

World textile fiber demand was 89.8 million tons in 2015 and is expected to grow to 93.7 million tons in 2016. Global demand for textile fibers is driven by population growth and by economic activity resulting in increasing wealth, particularly in emerging economies. While this overall trend is consistent across most major fibers, there are substantial disparities in the demand patterns of natu...

This paper presents the new mathematical model for determining the optimal ordering policy for industrial and commercial companies. In the previous research, the numerous inventory models under inflationary conditions have been developed. In these models, the demand rate, usually, has been considered constant and well known, time-varying, stock dependent or price-dependent. But, the demand rate...

We characterize the Ramsey optimal rate of inflation in a model with a foreign demand for domestic currency. In the absence of such demand, the model implies that the Friedman rule—deflation at the real rate of interest— is optimal. We show analytically that in the presence of a foreign demand for domestic currency, this result breaks down. Calibrated versions of the model deliver optimal annua...

This paper analyses dynamic pricing in markets with network externalities. Network externalities imply demand inertia, because the size of a network increases the usefulness of the product for consumers. Since past sales increase current demand, …rms have an incentive to set low introductory prices to be able to increase prices as their networks grow. However, in reality we observe decreasing p...

Abstract. A multi-objective inventory model with demand dependent unit cost and leading time has been formulated with storage space, number of orders and production cost as constraints. In most of the real world situations the cost parameters the objective function and constraints of the decision makers are imprecise in nature. A demand dependent unit cost is assumed and solved using Karush Kuh...

An efficient and accurate demand forecast becomes imperative for enhancement of commericial competitive advantage at al the stages of supply chain , escpically in the absence of collaborative supply chain management.Procurement decisions in the upstream supply chain to buy right quantity at right time for effective inventory management decisions depend on the accurate prediction of demand The o...

This paper represents a first attempt to study China’s business cycles using a formal analytical framework, namely, a structural VAR model. It is found that: (a) demand shocks were the dominant source of macroeconomic fluctuations, but supply shocks had gained more importance over time; (b) the driving forces of demand shocks were consumption and fixed investment in the first cycle of 1985–90, ...

To maintain an internally consistent representation with actual traffic conditions, this paper presents an OD demand consistency checking and updating model for on-line dynamic traffic assignment operation. Both predictive and reactive approaches are proposed to minimize (1) the deviations between simulated states and real-world observations and (2) OD demand adjustment magnitude. The two objec...

The impact of Trade Points on corporate performance depends on assumptions about returns to scale, types of games played, and size of gains in demand and revenues v i s á v i s costs. Specifically: (i) in a world of profitmaximizing firms, when the contribution of Trade Points to total revenues exceeds the additional costs, Trade Points help both small firms and large ones with the size of gain...
