We study the joint dynamic  pricing  and deteriorating inventory management problem in the presence of reference price and stock display effects. In a random potential market setting with convex replenishment/ordering and holding/shortage cost functions, the retailer replenishes/orders and sells a single deteriorating product over a continuous-time infinite horizon to maximize its profit. The demand rate depends negatively on the sales price and positively on the consumers' reference price and displayed stock quantity. The inventories deteriorate physically at a constant fraction of the on-hand stocks. A stochastic optimal control model is established to characterize the optimal policy in a linear feedback form of the state variables when the observed inventory level is either positive or negative. We also investigate the asymptotic behavior of the system and provide sufficient conditions for the stability and monotone convergence of the expected long-run behavior. Finally, we perform numerical examples to illustrate the theoretical results and sensitivity analysis to derive insights into deteriorating inventory management under reference price and stock display effects. The findings suggest that current reference price level has a positive effect while inventory level has a negative on the optimal replenishment rate and price. We characterize the sample paths of optimal strategies and find that the initial consumer reference price has an important impact on the firm's optimal operations management. On the expected long-run behavior,  it is beneficial for the firm to reduce demand uncertainty and deteriorating rate. We also observe that a large factor of displayed stock effect brings a positive effect on the total expected profit. Additionally, the firm needs to reduce (increase) the price and increase (reduce) the replenishment rate with high reference price effect intensity (memory factor).

Statistical Results

The present research investigates the effect of inventory performance on profitability. The objective is to find empirical evidence for the theory that operational excellence in inventory management improves profitability in the long run. To this end, the authors examine industry level longitudinal data (14 manufacturing industries at the SIC two-digit level) over the 1958-1999 period by employing a series of hierarchical regression analyses. The statistical results confirm that a lower inventory level measured as the industry inventory-to-sales ratio has a positive effect on industry profitability measured as the profit-to-sales ratio. This evidence is found significant in 9 out of the 14 U.S. manufacturing industries. This study also reveals that not all the inventories, categorized by stage of fabrication, equally contribute to improving industry profitability. For instance, the profitability of the primary and fabricated metal industries has benefited from reductions in finished goods inventories, whereas that of the petroleum and coal products industry has been affected mainly by declines in work-in-process inventories.

Joint Pricing

This paper utilizes the consumers’ reference price in prospect theory to analyze an omnichannel retailer’s multiperiod pricing and inventory management problem in which consumers can cancel their orders before payment and return the products after payment if the products do not meet their expectation. The omnichannel retailer’s optimal equilibrium pricing and ending inventory level are derived under reference price effects by maximizing the discounted total profit over the infinite planning horizon, where the optimal decisions we discussed under two scenarios: loss neutrality and loss aversion. The analysis shows that the convergence of the pricing and ending inventory level toward their equilibrium is from above or below, depending on the relative location of the initial reference price with respect to the unique equilibrium price. Moreover, a set of sensitivity analyses is discussed to characterize the impacts of system parameters on the optimal decisions. This research fills the gap of behavioral operation in the field of omnichannel joint pricing and inventory management.

Pos Data

This paper studies an inventory management problem faced by an upstream supplier that is in a collaborative agreement, such as vendor-managed inventory (VMI), with a retailer. A VMI partnership provides the supplier an opportunity to manage inventory for the supply chain in exchange for point-of-sales (POS)- and inventory-level information from the retailer. However, retailers typically possess superior local market information and as has been the case in recent years, are able to capture and analyze customer purchasing behavior beyond the traditional POS data. Such analyses provide the retailer access to market signals that are otherwise hard to capture using POS information. We show and quantify the implication of the financial obligations of each party in VMI that renders communication of such important market signals as noncredible. To help institute a sound VMI collaboration, we propose learn and screen—a dynamic inventory mechanism—for the supplier to effectively manage inventory and information in the supply chain. The proposed mechanism combines the ability of the supplier to learn about market conditions from POS data (over multiple selling periods) and dynamically determine when to screen the retailer and acquire his private demand information. Inventory decisions in the proposed mechanism serve a strategic purpose in addition to their classic role of satisfying customer demand. We show that our proposed dynamic mechanism significantly improves the supplier’s expected profit and increases the efficiency of the overall supply chain operations under a VMI agreement. In addition, we determine the market conditions in which a strategic approach to VMI results in significant profit improvements for both firms, particularly when the retailer has high market power (i.e., when the supplier highly depends on the retailer) and when the supplier has relatively less knowledge about the end customer/market compared with the retailer.

Neoclassical Growth Theory

Motivated by inter-regional disparities condition that occurs persistently, this study examines the Indonesian economy in the long run in order to know whether it tends to converge or diverge. This convergence is based on the Solow Neoclassical growth theory assuming the existence of diminishing returns to capital so that when the developed countries reach steady state conditions, developing countries will continuously grow up to 'catch-up' with developed countries. Based on regional economics perspective, each region can not be treated as a stand-alone unit,therefore, this study also focuses on the influence of spatial dependency and infrastructure. Economical and political situations of a region will influence policy in that region which will also have an impact to the neighboring regions. The estimation results of spatial cross-regressive model using fixed effect method consistently confirmed that the Indonesian economy in the long term will likely converge with a speed of 8.08 percent per year. Other findings are road infrastructure has a positive effect on economic growth and investment and road infrastructure are spatially showed a positive effect on economic growth. In other words, the investment and infrastructure of a region does not only affect the economic growth of that region but also to the economy of the contiguous regions.

This article models the endogenously interrelated relationship between global economic policy uncertainty (EPU), world industrial production (WIP), and the demand for US tourism net export (TNX) expenditures. To do so, we apply an identified structural vector autoregression model over monthly data spanning from January 1999 to October 2020. Our findings reveal that a positive shock in WIP has a significant positive effect on demand for TNXs. In contrast, unanticipated increases in price and EPU have a statistically significant negative effect on TNXs. Our results show that, in the long run, a one standard deviation shock in global EPU explains about 26.05% of the variations in tourism net service exports.

Inventory management remains a key challenge in supply chain management. Many companies recognize the benefits of a good inventory management system. An effective inventory management helps reaching a high customer service level while dealing with demand variability. In a complex supply chain network where inventories are found across the entire system as raw materials or finished products, the need for an integrated approach for managing inventory had become crucial. Modelling the system as a multi-echelon inventory system allows to consider all the factors related to inventory optimization. On the other hand, the high criticality of the pharmaceutical products makes the need for a sophisticated supply chain inventory management essential. The implementation of the multi-echelon inventory management in such supply chains helps keeping the stock of pharmaceutical products available at the different installations. This paper provides an insight into the multi-echelon inventory management problem, especially in the pharmaceutical supply chain. A classification of several multi-echelon inventory systems according to a set of criteria is provided. A synthesis of multiple multi-echelon pharmaceutical supply chain problems is elaborated.

Different policies impact on the growth of the telecommunication sector in Nigeria. One of these policies which influence the expansion or contraction of the telecommunication output is monetary policy. To this end, this research examined the effect of monetary policy on telecommunication output in Nigeria. For the purpose of analysis, time series secondary data were sourced from Central Bank of Nigeria (CBN) statistical bulletin covering the periods1986 to 2018. Autoregressive Distributed Lag (ARDL) technique was employed after examining the stationarity of the data series using Augmented Dickey-Fuller technique. The bound co-integration test revealed that there is long run equilibrium between the monetary policy variables employed and telecommunication output. The ARDL result revealed that money supply had significant and positive effect on telecommunication output in the short and long run; liquidity ratio produced an insignificant and negative relationship with telecommunication output in the short run and insignificant positive effect in the long run; exchange rate had insignificant negative effect in the short run and a significant positive effect on telecommunication output in the long run; consumer price index had significant negative influence on telecommunication outputboth in the short run and long run. The study concluded that monetary policy stimulates telecommunication output in Nigeria. Thus, it was recommended that the monetary authority should pursue an expansionary monetary policy to sustain the positive influence of money supply on telecommunication output in Nigeria while rolling out policy to reduce the liquidity ratio of banks in the short run but increase it in the long run so that the long term favourable effect of liquidity ratio can be felt on telecommunication output.
