Comparing Cournot and Bertrand equilibria in an asymmetric duopoly with product R&D

We compare the Cournot and Bertrand equilibria in an asymmetric duopoly with product R&D competition. If a firm’s marginal cost is lower than that of its rival, then this firm (its rival) is referred to as the more (less) efficient firm. Under each mode of competition, there are three types of equilibria: blockaded-entry, deterred-entry, and accommodated-entry. Moreover, the presence of R&D investment makes it harder for the less efficient firm to survive. Cournot competition entails a unique equilibrium, whereas Bertrand competition may yield two equilibria. It is harder for the less efficient firm to survive under Bertrand competition than under Cournot competition. Versus Cournot competition, Bertrand competition yields higher industry output, and it shifts production from the less efficient firm to the more efficient firm. This result, together with the known size effect, explains the following three findings. First, the more efficient firm has a normal output ranking, whereas the less efficient firm may demonstrate an output reversal. Second, the more efficient firm may demonstrate a R&D reversal, whereas the less efficient firm has a normal R&D ranking (its Cournot R&D effort exceeds its Bertrand R&D effort). Third, Bertrand competition is more welfare-efficient than Cournot competition.     

Bias Reduction in Dynamic Panel Data Models by Common Recursive Mean Adjustment*

The within‐group estimator (same as the least squares dummy variable estimator) of the dominant root in dynamic panel regression is known to be biased downwards. This article studies recursive mean adjustment (RMA) as a strategy to reduce this bias for AR(p) processes that may exhibit cross‐sectional dependence. Asymptotic properties for N,T→∞ jointly are developed. When ( log ²T)(N/T)→ζ, where ζ is a non‐zero constant, the estimator exhibits nearly negligible inconsistency. Simulation experiments demonstrate that the RMA estimator performs well in terms of reducing bias, variance and mean square error both when error terms are cross‐sectionally independent and when they are not. RMA dominates comparable estimators when T is small and/or when the underlying process is persistent.     

Restructuring of financial institutions and the corporate sector in Korea

This paper explores causes of the Korean currency crisis which started in November 1997. This paper also presents restructuring proposals and introduces the progress made so far. The urgency for quick restructuring and the necessity of the injection of money from both the government and foreign investors are emphasized. Restructuring of financial and corporate sectors should be pursued simultaneously. In the financial sector, the restructuring of banks should take precedence over other financial institutions. The key task in terms of bank restructuring involves the resolution of bad loans, recapitalization and the expedited reorganization of nonviable banks. Corporate reform is also important. Banks should play a central role in corporate workouts, especially in lowering excessive corporate debt and triggering corporate restructuring based on core competence. Transparency of corporate management, internationally accepted accounting practices, fuller disclosure requirements and stronger monitoring by minority shareholders are prerequisites for effective market discipline. Reform of ownership and governance structure are also important in enhancing managerial accountability of corporates as well as financial institutions.

A Theory of Economic Obsolescence

A new generation of durable goods makes an old generation economically, even if not physically, obsolete. Economic obsolescence due to technological innovation requires the durable goods monopolist to implement price discrimination in two dimensions, both between consumers with different valuations and between consumers with different purchase histories. Equilibrium in the game between the durable goods monopolist and consumers depends on the extent of economic obsolescence and the relative sizes of the consumer groups. Underinvestment in innovation may take place. This contrasts with the standard literature on planned obsolescence where the durable goods monopolist overinvests in durability reducing technology.     

LINKAGES: DO FOREIGN FIRMS BUY LOCALLY IN TAIWAN?*

Linkages are important potential impacts of DFI upon host economies. Since these potentialities are not necessarily realized, we must separate the potential (ex ante) and actual (ex post) results of these effects. Empirical data for Taiwan in the 1970s show that DFI may tend to concentrate in industries with strong backward linkages. More significantly, DFI located in EPZs or controlled by non-Chinese investors had a clear tendency to import more and, hence, to form enclaves. However, this group of firms greatly improved its procurement policies over time. Thus, while discernible in the short run, the enclavistic phenomenon linked to DFI becomes insignificant in the long run, as shown by Taiwan's experience. Needless to say, the gradual rise of the local content rate of foreign firms is in line with successful development of the local material industries in Taiwan in the 1970s (Schive, forthcoming). In addition to the time factor, several firms specific factors such as foreign ownership structure, export propensity, status as a producer of either final or intermediate goods, status as a “neighboring” or “distant” investor, and the scale of operation all have a bearing on foreign firms' local purchasing behavior. To determine whether these findings pertain to Taiwan only, further country comparative studies are needed.     

Evaluating Industrial Relations Systems of OECD Countries from 1993 to 2005: A Two‐Dimensional Approach

This article uses both cross‐sectional and longitudinal methods to evaluate the national industrial relations systems of 30 Organisation for Economic Co‐operation and Development (OECD) countries from 1993 to 2005. We adopt a pluralistic view of industrial relations that gives equal weight to efficiency and equity, along with a general systems model consisting of input, process and output. We rank each country in terms of a combined score of efficiency and equity. We find that the 30 OECD countries can be separated into three distinct groups (high on both equity and efficiency; high on efficiency but low on equity; moderate on equity and low on efficiency), and that these groups exhibit considerable stability over time.     

Bringing Political Skill into Social Networks: Findings from a Field Study of Entrepreneurs

The authors integrate the entrepreneurship literature's sociological and behavioural perspectives and examine the processes through which entrepreneurs first build social networks and then use the network resources for enhancing venture performance. Field interviews of entrepreneurs during a six‐month period reveal that political skill is an important individual‐level factor that influences the construction and use of social networks. Theoretical and practical implications of the major findings are discussed.     

Effects of dominance transitions on advice adherence in professional service conversations

For many professional services, advice adherence is a necessary condition for achieving service success for both customers and service providers. Despite their pivotal roles in value co-creation, typical conversational interactions often lead to low adherence. We propose that enabling a “dominance transition,” from provider dominance in the pre-advice stage to customer dominance in the post-advice stage, enhances advice adherence because it increases customers’ perceived common ground. Furthermore, providers’ consultation focus, customers’ prior knowledge, and customers’ perceived adherence effort moderate this process. Using mixed methods, including both empirical modeling and controlled and field experiments, we validate the proposed model in various contexts (healthcare, financial services, and fitness and wellness counseling). The findings establish several theoretical contributions and offer managerial implications for improving advice adherence by managing dominance transitions in conversational interactions more effectively through training service providers or even programming AI chatbots.

     

Theory-Driven Choice Models

We explore issues in theory-driven choice modeling by focusing on partial-equilibrium models of dynamic structural demand with forward-looking decision-makers, full equilibrium models that integrate the supply side, integration of bounded rationality in dynamic structural models of choice and public policy implications of these models.
