Multiskilling, Delegation, and Continuous Process Improvement: A Comparative Analysis of U.S.-Japanese Work Organizations

This paper focuses on the following U.S.-Japanese differences in work organizations and labor market practices: in Japanese firms, (i) real decision-making authority is delegated more to lower hierarchical levels, (ii) employees are multiple-skilled, (iii) human capital accumulation is more firm-specific, (iv) labor turnover rate is lower, and (v) continuous process improvement is more prevalent. I present a model that addresses interconnections among three key features of work organizations (multiskilling, delegation, and continuous process improvement), and analyses ways in which they are related to labor market practices. It analyses strategic interactions among firms concerning their choices of the nature of work organizations, and shows that strategic complementarity due to labor market externality can yield the multiplicity of equilibria, which provides a systematic explanation for the U.S.-Japanese differences.Delegation, Multiskilling, Process Improvement, U.S.-Japanese Differences, Work Organization

Formal Contracts, Relational Contracts, and the Threat-Point Effect

Can formal contracts help resolving the holdup problem? We address this important question by studying the holdup problem in repeated transactions between a seller and a buyer in which the seller can make relation-specific investments in each period. In contrast to previous findings, we demonstrate that writing a simple fixed-price contract based on product delivery is of value even when relation-specific investment is purely cooperative. In particular, there is a range of parameter values in which a higher investment can be implemented only if a formal fixed-price contract is written and combined with an informal agreement on additional payments or termination of future trade, contingent upon investments. Furthermore, we show that under an additional natural assumption, focusing our attention on fixed-price contracts as a form of formal contracts is without loss of generality. The key driving force of our result is a possibility that the threat-point effect is negative, i.e., the relation-specific investment decreases the surplus under no trade. This possibility, although very plausible, has been largely ignored in previous theoretical/empirical analyses of the holdup problem.holdup problem, formal contract, relational contract, cooperative investment, fixed-price contract, relation-specific investment, repeated transactions, long-term relationships

Differentiated duopoly under vertical relationships with communication costs

Platform sharing across manufacturers has recently become common practice in the automobile industry. Its important objective is to reduce procurement costs by taking advantage of the commonality of components, but this often reduces the degree of product differentiation. We investigate this trade-off through analyzing a model that incorporates manufacturer-supplier relationships with communication costs into a standard differentiated duopoly model, and find an interesting inverse relationship between the advantage of platform sharing and the costs for manufacturers to communicate with their potential suppliers. The result suggests that the information-technology revolution could be a reason for the recent prevalence of platform sharing in the automobile industry, and predicts that similar phenomena would prevail in various other industries as the IT revolution makes further progress. We then consider an extension of our model that incorporates an option for the manufacturers to jointly establish a B2B electronic marketplace in order to reduce their communication costs, and explore its welfare implications. Although the joint establishment of an e-marketplace could be viewed as an anticompetitive activity, we find that in our framework it increases welfare.Communication cost, differentiated duopoly, electronic commerce, electronic marketplace, manufacturer-supplier relationships, platform sharing, product differentiation

Competition, Monopoly Maintenance, and Consumer Switching Costs

Significant attention has been paid to why a durable-goods producer with little or no market power would monopolize the maintenance market for its own product. This paper provides an explanation for this practice that is based on consumer switching costs and the choice of consumers between maintaining and replacing used units. In our explanation, if a firm does not monopolize the maintenance market for its own product, then consumers sometimes maintain used units when it would be efficient for the units to be replaced. In turn, the return to monopolizing the maintenance market is that the practice allows the firm to avoid this inefficiency. An interesting aspect of our analysis that has significant public-policy implications is that, in contrast to most previous explanations for why a durable-goods producer with little or no market power would monopolize the maintenance market for its own product, in our explanation the practice increases rather than decreases both social welfare and consumer welfare.durable goods; aftermarkets; switching costs

Impacts of the Information-technology Revolution on Japanese Manufacturer-supplier Relationships

'Vertical keiretsu', characterized by suppliers' willingness to make customized investments and their long-term relationships with manufacturers, had been recognized as an important source of strength in Japanese industries. Our model predicts that, in contrast to the recent popular argument, the information-technology revolution can strengthen 'vertical keiretsu'. This is because the efficiency of designing customized parts is significantly enhanced if suppliers undertake a substantial level of IT investments such as the introduction of 3D CAD systems, and the customized nature of such investments could reduce the number of potential suppliers. Our interviews with Japanese manufacturers provide a support to this prediction.Customized investment, Information technology, Japanese firm, Vertical Keiretsu, Subcontracting

International Credit and Welfare: Some Paradoxical Results with Implications for the Organization of International Lending

This paper models a developing nation that faces a foreign exchange shortage and hence its demand for foreign goods is limited both by its income and its foreign exchange balance. Availability of international credit relaxes the second constraint. It is shown that in this setting the availability of international credit at concessionary rates can leave the borrowing nation worse off than if it had to borrow money at higher market rates. This ‘paradox of benevolence’ is then used to motivate a discussion of policies pertaining to international lending and the Southern government’s method of rationing out foreign exchange to the importers.

International Credit and Welfare: A Paradoxical Theorem and Its Policy Implications

This paper considers a developing nation that faces a foreign exchange shortage and hence its demand for foreign goods is limited both by its income and its foreign exchange balance. Availability of international credit relaxes the second constraint. We develop a simple model of strategic interaction between lending institutions and firms, and show that the availability of international credit at concessionary rates can leave the borrowing nation worse off than if it had to borrow money at higher market rates. This 'paradox of benevolence' is then used to motivate a discussion of policies pertaining to international lending and the Southern government's method of rationing out foreign exchange to the importers.

Formal Contracts, Relational Contracts, and the Holdup Problem

We study the holdup problem in repeated transactions between a seller and a buyer such that the seller makes relation-specific investments in each period. We show that where, under spot transaction, formal contracts have no value because of the cooperative nature of investment, writing a simple fixed-price contract can be valuable under repeated transactions: There is a range of parameter values in which a higher investment can be implemented only if a formal price contract is written and combined with a relational contract. We also show that there are cases in which not writing a formal contract but entirely relying on a relational contract increases the total surplus of the buyer and the seller. The key condition is how the investment affects the renegotiation price in general, and the alternative-use value in particular.holdup problem, formal contract, relational contract, cooperative investment, fixed-price contract, relation-specific investment, renegotiation, repeated transactions, long-term relationships

Symbols, Group Identity and the Hold-up Problem

Groups, companies, and organizations identify themselves via symbols. Symbols have the potential to create group identity and at the same time create group boundaries, thus allowing for achieving the benefits of cooperation by ingroup members. We use a laboratory experiment to study the role of group identity, created by the use of symbols, in mitigating the hold-up problem. As a team symbol we employ color t-shirts. We find that the usage of t-shirts itself does not create a strong enough group identity to mitigate the hold-up problem. However, in our previous research, we found that group identity created by t-shirts and a group chat aimed to help team members to solve a task is capable of resolving the hold-up problem. These findings are consistent with the everyday practice where organizations often make significant investments in team-building and socialization activities, suggesting that an important objective of such activities might be to strengthen group identity so that it is effective even in highly strategic environments.altruism; experiment; group identity; hold-up problem; other-regarding preferences; relation-specific investment; symbols; team membership

An Economic Analysis of Platform Sharing

We explore the managerial implications and economic consequences of platform sharing under models of horizontal and vertical product differentiation. By using a common platform across different products, firms can save on fixed costs for platform development. At the same time, platform sharing imposes restrictions on firms' ability to differentiate their products, and this reduces their profitability. It might appear that platform sharing across firms makes consumers worse off because firms cooperate in their product development processes to maximize their joint profit. We find, however, that platform sharing across firms benefits consumers in our framework because it intensifies competition in our horizontal differentiation model, and because it increases the quality of the lower-end product in our vertical differentiation model. We also show new channels through which a merger makes consumers worse off in the presence of platform sharing.
