摘要：We model and estimate the effects to downstream productivity from information technology (IT) investments made upstream. Specifically, we examine how an industry's productivity is affected by the IT capital stock of its suppliers. These supplier-driven IT spillovers occur because, due to competition in the supplying industry, quality benefits from suppliers' IT investments can pass downstream. If the output deflators of supplying industries (consequently the intermediate input deflator of the ...

摘要：Companies such as Zara and World Co. have recently implemented novel product development processes and supply chain architectures enabling them to make more product design and assortment decisions during the selling season, when actual demand information becomes available. How should such retail firms modify their product assortment over time in order to maximize overall profits for a given selling season? Focusing on a stylized version of this problem, we study a finite horizon multiarmed ban...

摘要：This paper analyzes sequential auctioning of single units of an indivisible good to a fluctuating population composed of overlapping generations of unit-demand bidders. Two phenomena emergent in such a market are investigated: forward-looking bidding strategies, and closed-loop selling strategies that involve learning from past prices. The buyers shade their bids down, i.e., bid less than they would in a single isolated auction, whenever they expect the seller to sell another unit of the good ...

摘要：This study examines whether individuals, groups, and organizational units learn from experience in software development and whether this learning improves productivity. Although prior research has found the existence of learning curves in manufacturing and service industries, it is not clear whether learning curves also apply to knowledge work like software development. We evaluate the relative productivity impacts from accumulating specialized experience in a system, diversified experience in...

摘要：In this paper, a market-based decomposition method for decomposable linear systems is developed. The solution process iterates between a master problem that solves the market-matching problem, and subproblems that solve the agents' bundle-determination problems. Starting from any initial price and feasible allocation, system optimality can be achieved under a dynamic market-trading algorithm in a finite number of trades. The final market-clearing prices are discovered by this market trading an...

摘要：Scholars who view organizational, social, and technological systems as sets of interdependent decisions have increasingly used simulation models from the biological and physical sciences to examine system behavior. These models shed light on an enduring managerial question: How much exploration is necessary to discover a good configuration of decisions? The models suggest that, as interactions across decisions intensify and local optima proliferate, broader exploration is required. The models ...

摘要：Consider a firm developing an innovative product. Due to market pressures, production must begin soon after the product development effort is complete, which requires that an upstream supplier invests in capacity while the design of the product and production process are in flux. Because the product is ill-defined at this point in time, the firms are unable to write court-enforceable contracts that specify the terms of trade or the supplier's capacity investment. However, the firms can adopt a...

摘要：In a variety of industries ranging from agriculture to electronics and oil, procurement takes place through a combination of bilateral fixed-price contracts and open market trading among supply chain participants, which allows them to improve supply chain performance by utilizing new demand and cost information. The strategic behavior of the participants in these markets interacts with the way fixed-price contracts are formulated and significantly affects supply chain efficiency. In this paper...

摘要：We study the optimal levels of advertising and promotion budgets in dynamic markets with brand equity as a mediating variable. To this end, we develop and estimate a state-space model based on the Kalman filter that captures the dynamics of brand equity as influenced by its drivers, such as the brand's advertising and sales promotion expenditures. By integrating the Kalman filter with the random coefficients logit demand model, our estimation allows us to capture the dynamics of brand equity a...

摘要：The structure of alliance networks influences their potential for knowledge creation. Dense local clustering provides information transmission capacity in the network by fostering communication and cooperation. Nonredundant connections contract the distance between firms and give the network greater reach by tapping a wider range of knowledge resources. We propose that firms embedded in alliance networks that exhibit both high clustering and high reach (short average path lengths to a wide ran...
