We characterize a duopoly buffeted by demand and cost shocks. Firms learn about shocks from common observation, private observation, and noisy price signals. Firms internalize how outputs affect a rival's signal, and hence output. We distinguish how the nature of information —public versus private—and of what firms learn about—common versus private values—affect equilibrium outcomes. Firm outputs weigh private information about private values by more than common values. Thus, prices contain more information about private‐value shocks. 相似文献

In direct competition between national brands of consumer packaged goods (CPG), one brand often has a large local share advantage
over the other despite the similarity of the branded products. I present an explanation for these large and persistent advantages
in the context of local competition on perceived quality or brand image. The main result of the analysis is a relation between
varying degrees of product similarity and equilibrium outcomes of local share advantages. Namely, I find that asymmetric quality
positioning and associated local share advantages emerge especially when competing brands are objectively similar. Conversely,
local share asymmetries based on brand positioning occur less when brands are dissimilar. This paper provides two reinforcing
intuitions for this result. First, if brands are objectively similar, different levels of investment in local quality perceptions
co-exist in equilibrium in the same market, because this investment is often borne as fixed cost. Also, early movers will
invest in high perceived quality, whereas late movers have less incentive to invest because of demand sharing and increased
price competition. Second, if the local advantages are shared by competitors across markets, the persistence of these advantages
is reinforced by multimarket contact. Even when local brand building is free, firms may not want to improve perceived quality
in their “weak” markets if it initiates retaliation by the competition in their “strong” markets. The increase in multimarket
profits from collusion is large when the products are similar, because price competition looms large.

A model is developed to explain participation and spending on R&D as a function of firm size. The R&D process is represented as an n-participant race with a Poisson incidence of success, where the winner takes all during some protection period. Four effects of scale are taken into account: a sunk fixed threshold cost of entry; a flow cost of expenditure for the duration of the race, which affects both the profitability of winning and the speed of development (the Poisson parameter), both with diminishing returns; allowance for an effect of firm size on the effectiveness (profit/cost) of development. The operational decision concerning the level and intensity of commitment in case of participation is modelled in a traditional fashion as the maximization of expected returns. The strategic decision whether or not to participate (at an optimal level and intensity) is modelled as a stochastic process of deliberation between different makers and influencers of decisions in the firm. The latter is to be seen as an introduction of the political and resource dependence views of organisations. The resulting model of R&D participation as a function of firm size is tested empirically on data from an R&D survey in the Netherlands. 相似文献

We revisit Kyle’s (Econometrica 53:1315–1335, 1985) model of price formation in the presence of private information. We begin by using Back’s (Rev Financ Stud 5(3):387–409, 1992) approach, demonstrating that if standard assumptions are imposed, the model has a unique equilibrium solution and that the insider’s trading strategy has a martingale property. That in turn implies that the insider’s strategies are linear in total order flow. We also show that for arbitrary prior distributions, the insider’s trading strategy is uniquely determined by a Doob $h$ -transform that expresses the insider’s informational advantage. This allows us to reformulate the model so that Kyle’s liquidity parameter $\lambda $ is characterized by a Lagrange multiplier that is the marginal value or shadow price of information. Based on these findings, we can then interpret liquidity as the marginal value of information. 相似文献

Estimating International Technology Spillovers Using Technology Flow Matrices. — This paper investigates the impact of international R &; D spillovers on sectoral growth patterns in OECD countries. It applies panel regression techniques to a time-series cross-section panel. It arrives at the conclusion that knowledge spillovers are an important contributor to economic growth. The estimation results are applied in the form of a ‘simulation’ of TFP growth per country, splitting (R &; D-related) TFP into a component due to domestic R &; D and one due to foreign R &; D. The results also show that the United States and Germany are the most influential countries in terms of contributions to other countries’ TFP growth. 相似文献

Companies increasingly face the need for transformation in today’s rapidly changing business environment, characterized by major shifts in technology, regulation, and customer behavior. A lack of strategic risk insight and foresight leaves many incumbents insufficiently prepared in the face of such deep uncertainty. We argue that traditional risk management falls short because it predominantly focuses on strategy execution while leaving strategy formulation largely untouched. Moreover, an administrative-heavy risk management process can create strategic inertia and a misleading sense of control. In today’s dynamic business context, companies must not only increase the speed and impact of their strategy execution but also continuously explore the development of new strategies in response to disruptive events or emerging opportunities. Our research shows how leading companies develop a strategic risk management (SRM) capability to increase their resilience and agility in response to deep uncertainty. SRM takes a strategic, forward-looking perspective and focuses on strengthening processes, people, and practices for purposefully integrating risk into the strategy formulation process. This article offers a framework with three proven configurations of content and timing integration, risk management roles, and leading practices that enable effective SRM. 相似文献

Food price variation is typical of the food economies of many low income countries. The presence or absence of road infrastructure is perceived to be one of the main determinants of this variation. This analysis shows that in the case of the former Zaire, food price dispersion is significant both across products and across regions. It is demonstrated that transportation costs explain most of the differences in food prices between producer regions and that road quality is an important factor in the transportation costs. However, food prices decrease relatively faster than transportation costs increase and traders' wages are higher on bad roads. 相似文献
