strategic capacity rationing to induce early purchases dynamic pricing offers the potential to increase revenues at the same time it creates an incentive for customers to strategize over the timing of their purchases a firm should ideally account for this behavior when making its pricing and stocking decisions in particular we investigate whether it is optimal for a firm to create rationing risk by deliberately understocking products then the resulting threat of shortages creates an incentive for customers to purchase early at higher prices but when does such a strategy make sense if it is profitable to create shortages what is the optimal amount of rationing risk to create we develop a stylized model to study this problem in our model customers have heterogeneous valuations for the firm s product and face declining prices over two periods customers are assumed to have identical risk preferences and know the price path and fill rate in each period via its capacity choice the firm is able to control the fill rate and hence the rationing risk faced by customers customers behave strategically and weigh the payoff of immediate purchases against the expected payoff of delaying their purchases we analyze the capacity choice that maximizes the firm s profits first we consider a monopoly market and characterize conditions under which rationing is optimal we examine how the optimal amount of rationing is affected by the magnitude of price changes over time and the degree of risk aversion among customers we then analyze an oligopoly version of the model and show that competition reduces the firms ability to profit from rationing indeed there exists a critical number of firms beyond which a rationing equilibrium cannot be supported

business groups and product variety in trade evidence from south korea taiwan and japan abstract we analyze the impact of market structure on the trade performance of south korea taiwan and japan south korea has many large vertically integrated business groups known as chaebol whereas business groups in taiwan are smaller and more specialized in the production of intermediate inputs we test the hypotheses that a greater presence of business groups leads to less product variety but higher product quality using data on exports from these countries to the united states we find that taiwan tends to export a greater variety of products to the us than korea and this holds particularly for final goods in addition taiwan exports higher quality intermediate inputs whereas korea exports higher quality final goods a comparison with japan is also presented which has greater product variety in its sales to the us than either taiwan or korea due to its larger size

the competitive newsboy we consider a competitive version of the classical newsboy problem in which a firm must choose an inventory or production level for a perishable good with random demand and the optimal solution is a fractile of the demand distribution and investigate the impact of competition upon industry inventory a splitting rule specifies how initial industry demand is allocated among competing firms and how any excess demand is allocated among firms with remaining inventory we examine the relation between equilibrium inventory levels and the splitting rule and provide conditions under which there is a unique equilibrium our most general result is that if all excess demand is reallocated i e there is perfect substitutability then competition never leads to a decrease in industry inventory

dynamic pricing strategies with reference effects we consider the dynamic pricing problem of a monopolist firm in a market with repeated interactions where demand is sensitive to the firm s pricing history consumers have memory and are prone to human decision making biases and cognitive limitations as the firm manipulates prices consumers form a reference price that adjusts as an anchoring standard based on price perceptions purchase decisions are made by assessing prices as discounts or surcharges relative to the reference price in the spirit of prospect theory we prove that optimal pricing policies induce a perception of monotonic prices whereby consumers always perceive a discount respectively surcharge relative to their expectations the effect is that of a skimming or penetration strategy the firm s optimal pricing path is monotonic on the long run but not necessarily at the introductory stage if consumers are loss averse we show that optimal prices converge to a constant steady state price characterized by a simple implicit equation otherwise the optimal policy cycles the range of steady states is wider the more loss averse consumers are steady state prices decrease with the strength of the reference effect and with customers memory all else equal offering lower prices to frequent customers may be suboptimal however if these are less sensitive to price changes than occasional buyers if managers ignore such long term implications of their pricing strategy the model indicates that they will systematically price too low and lose revenue our results hold under very general reference dependent demand models

measuring quality change in quota constrained import markets the case of u s footwear abstract theoretical models predict that quantitative import restrictions such as orderly marketing agreements omas lead to substitution into higher quality products within the quotaconstrained import category the country specific nature of omas results in further substitution among supplying countries using index number techniques this paper measures the impact of product and country substitution on the price of u s footwear imports in the period surrounding the 1977 1981 footwear oma with korea and taiwan upgrading of the import bundle was observed in most quota categories throughout the oma period and accounted for 12 percent of the observed rise in the average price of footwear imports

a new product growth for model consumer durables this article originally appeared in management science january 1969 volume 15 number 5 pp 215 227 published by the institute of management sciences a growth model for the timing of initial purchase of new products is developed and tested empirically against data for eleven consumer durables the basic assumption of the model is that the timing of a consumer s initial purchase is related to the number of previous buyers a behavioral rationale for the model is offered in terms of innovative and imitative behavior the model yields good predictions of the sales peak and the timing of the peak when applied to historical data a long range forecast is developed for the sales of color television sets

toward an economic model of the japanese firm i owe a great deal to professor moses abramovitz who suggested that i write this article i appreciate his constant encouragement and guidance which aided me throughout its preparation i am also indebted to three anonymous referees of the journal and to professors ryutaro komiya and michael riordan for their critical comments and helpful suggestions needless to say i am solely responsible for the views expressed in this paper

coase revisited business groups in the modern economy ronald coase s celebrated query as to why economic actors typically aggregate into entities called firms rather than transacting as individuals in a market has engendered a vigorous stream of research this paper asks a parallel question why is it that in all modern economies firms themselves aggregate into larger entities often more stable than any literature predicts which are here referred to as business groups after establishing some working definitions and discussing the curious conjunction of empirical importance and analytical invisibility of business groups an attempt is made to establish the most significant dimensions along which such groups vary we end with some speculations on the role of these groups in economic development copyright 1995 by oxford university press

keiretsu and relationship specific investment a barrier to trade this article develops a model of informal procurement within japanese keiretsu so as to consider effects on intermediate good imports such as auto parts parts suppliers make relationship specific investments that benefit the automaker and prices are determined by bargaining after investment has been sunk although this investment raises efficiency it limits the range of imports to less important parts such as tailpipes and it is possible that no parts are imported despite lower foreign costs lack of information concerning investment rents combined with counterintuitive responses of imports to changes in output and costs could create unwarranted perceptions of a trade barrier

what does japanese trade structure tell us about japanese trade policy some argue foreign access to japanese markets remains tightly controlled and that if japan is to be a member in good standing of the international economic system japan must do more than just adhere to the formal rules of the gatt japan must show by the results of its international economic transactions that foreign access to its market is not tightly controlled as this point of view is increasingly dominating american economic diplomacy with japan it is particularly important that its premise be examined first i examine japan s growth record and trade record to the extent that japan s trade performance is different i explore whether the difference can legitimately be attributed to japanese policies this paper finds that neither the price behavior of japanese firms nor the pattern and volume of what japan imports or exports suggests that japan s trade regime is different some of japan s economic institutions may be distinctive but there is little evidence they produce outcomes which distort the international economic system what remains to be explained is the conviction of so many that japan is more a parasite than a pillar of the international economic system the record of economic research directly and indirectly bearing on this issue does not support such a conclusion at all

buyer investment export variety and intrafirm trade abstract this paper studies a model of buyer investment and its effect on the variety and vertical structure of international trade a distinction is made between two types of buyer investment flexible and specific which differ in the ability of a buyer to match with a seller the interaction of buyer investment with the entry and pricing incentives of suppliers are analyzed it is shown that i there can be multiple equilibria in the variety of products traded and ii less product variety is associated with more intrafirm trade the possibility of multiple equilibria is consistent with the observation that some similar economies such as taiwan and south korea differ substantially in their export varieties to the u s a cross country empirical analysis confirms the negative correlation between export variety and intrafirm trade

monopolistic competition and international trade reconsidering the evidence we test some propositions about international trade flows that are derived from models of monopolistic competition developed by elhanan helpman and paul krugman we investigate whether the volume of trade between oecd countries is consistent with the predictions of a model in which all trade is intraindustry trade in differentiated products we then repeat the test with non oecd countries we also investigate whether the share of intraindustry trade is consistent with a more general theoretical model in which some but not all trade is intraindustry trade our results lead us to question the apparent empirical success of these models

international trade and the internal organization of firms an evolutionary approach masahiko aoki and others have distinguished two alternative modes for a firm s internal organization we argue that the profitability of each mode depends on the distribution of firms across modes and on the general economic environment we characterize the evolutionary equilibria in both a parametric and a general model and argue that corner equilibria predominate we analyze the effects of trade between the two countries in a outputs only and b inputs factors as well as outputs our most striking conclusion is that in case b a less efficient mode can displace a more efficient mode when trade barriers are sufficiently low

the informational aspect of the group buying mechanism abstract this paper studies the group buying mechanism from a dynamic perspective we consider a seller that offers a product in the form of group buying priced low but uncertain and spot purchasing priced high but guaranteed in the case of group buying the information associated with the number of participating customers is updated in the middle of the sale customers are assumed to be strategic with a time dependent utility in addition to choosing between spot purchasing and group buying customers could choose to delay their decisions until the information update we characterize the customer behavior within a rational expectations framework we then consider the effect of information and demand dynamics our results show that whereas an improvement in information quality has a positive effect on customer surplus and the group buying success rate the effect of inter temporal demand correlation is mixed we also discuss the seller s profit maximization problem and derive the condition to be satisfied at the optimal group size

a market power based model of business groups we propose an model of vertically and horizontally integrated business groups that allows the number and size of each group to be determined endogenously we find that more than one configuration of groups can arise in equilibrium several different types of business groups can occur each of which are consistent with profit maximization and are stable we suggest that the strongly integrated groups arising in the model characterize the chaebol found in south korea whereas the less integrated groups describe those found in taiwan

corporate structure liquidity and investment evidence from japanese industrial groups this paper presents evidence suggesting that information and incentive problems in the capital market affect investment we come to this conclusion by examining two sets of japanese firms the first set has close financial ties to large japanese banks that serve as their primary source of external finance and are likely to be well informed about the firm the second set of firms has weaker links to a main bank and presumably faces greater problems raising capital investment is more sensitive to liquidity for the second set of firms than for the first set the analysis also highlights the role of financial intermediaries in the investment process

kinship cooperation and the evolution of moral systems across the social sciences a key question is how societies manage to enforce cooperative behavior in social dilemmas such as public goods provision or bilateral trade according to an influential body of theories in psychology anthropology and evolutionary biology the answer is that humans have evolved moral systems packages of functional psychological and biological mechanisms that regulate economic behavior including a belief in moralizing gods moral values negative reciprocity and emotions of shame guilt and disgust based on a stylized model this article empirically studies the structure and evolution of these moral traits as a function of historical heterogeneity in extended kinship relationships the evidence shows that societies with a historically tightly knit kinship structure regulate behavior through communal moral values revenge taking emotions of external shame and notions of purity and disgust in loose kinship societies on the other hand cooperation appears to be enforced through universal moral values internalized guilt altruistic punishment and an apparent rise and fall of moralizing religions these patterns point to the presence of internally consistent but culturally variable functional moral systems consistent with the model the relationship between kinship ties economic development and the structure of the mediating moral systems amplified over time

pricing and manufacturing decisions when demand is a function of prices in multiple periods in most deterministic manufacturing decision models demand is either known or induced by pricing decisions in the period that the demand is experienced however in more realistic market scenarios consumers make purchase decisions with respect to price not only in the current period but also in past and future periods we model a joint manufacturing pricing decision problem accounting for that portion of demand realized in each period that is induced by the interaction of pricing decisions in the current period and in previous periods we formulate a mathematical programming model and develop solution techniques we identify structural properties of our models and develop closed form solutions and effective heuristics for various special cases of our models finally we conduct extensive computational experiments to quantify the effectiveness of our heuristics and to develop managerial insights

globalization and upgrading what can and cannot be learnt from international trade statistics in the wood furniture sector the measurement of innovation is a complex and ambiguous challenge two broad families of measures have been used those focusing on inputs and those focusing on outputs each has its strengths and weaknesses but neither is able to capture the growing importance of product innovation adequately in this paper we attempt to throw more light on the measurement of product innovation through the complementary use of data on unit price and market share the analysis is distinctive through its exclusive use of trade data these measures are applied to the global furniture industry through an analysis of imports into the eu between 1989 and 2001

market culture and authority a comparative analysis of management and organization in the far east three frameworks purport to explain industrial arrangements and practices a market approach that emphasizes economic characteristics a cultural approach that sees organization as the expression of patterned values and an authority approach that explains organization as a historically developed structure of domination the efficacy of each approach is tested in explaining the organizational structures of three rapidly growing east asian economies japan south korea and taiwan the paper argues through comparative analysis that organizational growth is best explained by market and cultural factors but that authority patterns and legitimation strategies best explain organizational structure

purchasing pricing and quick response in the presence of strategic consumers we consider a retailer that sells a product with uncertain demand over a finite selling season the retailer sets an initial stocking quantity and at some predetermined point in the season optimally marks down remaining inventory we modify this classic setting by introducing three types of consumers myopic consumers who always purchase at the initial full price bargain hunting consumers who purchase only if the discounted price is sufficiently low and strategic consumers who strategically choose when to make their purchase a strategic consumer chooses between a purchase at the initial full price and a later purchase at an uncertain markdown price in equilibrium strategic consumers and the retailer make optimal decisions given their rational expectations regarding future prices availability of inventory and the behavior of other consumers we find that the retailer stocks less takes smaller price discounts and earns lower profit if strategic consumers are present than if there are no strategic consumers we find that a retailer should generally avoid committing to a price path over the season assuming such commitment is feasible committing to a markdown price or to not mark down at all is often too costly inventory may remain unsold even in the presence of strategic consumers the better approach is to be cautious with the initial quantity and then mark down optimally furthermore we discuss the value of quick response the ability to procure additional inventory after obtaining updated demand information albeit at a higher unit cost than the initial order we find that the value of quick response to a retailer is generally much greater in the presence of strategic consumers than without them on average 67 more valuable and as much as 558 more valuable in our sample in other words although it is well established in the literature that quick response provides value by allowing better matching of supply with demand it provides more value often substantially more value by allowing a retailer to control the negative consequences of strategic consumer behavior
