We introduce an irregular network structure into a model of frictional, on‐the‐job search in which workers find jobs through their network connections or directly from firms. We show network‐found jobs have higher wages, and thus better‐connected workers climb the job ladder faster. The mean field approach allows us to formulate heterogeneous workers' recursive problem tractably. Our calibration is consistent with several empirical findings because of a composition—not information—effect. We also introduce new model‐consistent evidence: Job‐to‐job switches at higher ladder rungs are more likely to use networks. 相似文献

Does corporate international diversification destroy value? Evidence from cross-border mergers and acquisitions 总被引:1,自引:1,他引:0

This paper investigates the valuation effects of corporate international diversification by examining cross-border mergers and acquisitions of US acquirers over the period 1990–2000. We find that, on average, acquisitions of “fairly valued” foreign business units do not lead to value discounts. In contrast, unrelated cross-border acquisitions result in a significant diversification discount of about 24% after accounting for the valuation of foreign targets. Furthermore, significant wealth gains accrue to foreign target shareholders regardless of the type of acquisition. Overall, our results suggest that international diversification does not destroy value while industrial diversification leads to discounts even after controlling for the pre-acquisition value of the target. 相似文献

Tacit collusion with imperfect monitoring in the Canadian manufacturing industry: an empirical study
This article undertakes a cross-sectoral analysis of a salient empirical implication of the model of tacit collusion advanced by Abreu, Pearce, and Stachetti (1986). Specifically, we assess the prevalence of a first-order Markovian process for alternating between price wars and collusive periods through nonparametric tests. The analysis focuses on 30 different industries in Canada. The evidence provides weak support for optimal collusion in one industry, which is consistent with the idea that such kind of collusive arrangements is unusual, or, if collusion is all too common, that price wars as deviations from collusion are rare. 相似文献

The paper investigates implications of different theoretical models for hierarchical structure. A sample of 6,578 firms in
the Brazilian manufacturing industry is considered and explanatory factors pertaining to structural characteristics, network
technology, technological innovations, managerial innovations and incentive mechanisms are investigated. Important joint effects
are detected for all groups of variables in partial contrast with the related previous literature. Moreover, one detects significant
joint effect of the newly considered group of incentive variables. The evidence in terms of individual effects is largely
consistent with the predicted effects from the theoretical literature. 相似文献

The article investigates the determinants of newly created industrial establishments in Brazil in 1997 taking as reference explanatory variables referring to market structure and industry dynamics, stronger effects are detected for larger firms. Minimum efficient scale, industry size, industry growth and turbulence display the expected positive effects on firm size, but the intensity of those are more pronounced for larger firms. The suboptimal scale variable, on the other hand, exhibits a counterintuitive positive effect and perhaps other types of barriers to entry that are not related to scale aspects may be important in the Brazilian case. 相似文献

This paper studies the impact of attitudinal loyalty and trust in entrepreneurship, following a client-focused strategy. In this context, trust and commitment are the cornerstone of relationship marketing, and contributes positively to achieving attitudinal loyalty, which is suitable for the maintenance of relationships over time. This variable also acts as a facilitator or mediator on the influence satisfaction has on loyalty. We show that satisfaction has a positive impact on trust and attitudinal loyalty. Following structural equation modelling methodology we test all the relationships in a sample composed by travel agency customers. 相似文献

We review one method for estimating the modulus of continuity of a Schramm–Loewner evolution (SLE) curve in terms of the inverse Loewner map. Then we prove estimates about the distribution of the inverse Loewner map, which underpin the difficulty in bounding the modulus of continuity of SLE for $\kappa =8$ . The main idea in the proof of these estimates is applying the Girsanov theorem to reduce the problem to estimates about one-dimensional Brownian motion. 相似文献

The paper discusses optimal short-term borrowing in response to an increase in the price of imported inputs. The rationale for borrowing lies in the increase in substitution possibilities in production (between imported and domestic inputs) and in consumption (between traded and non-traded goods) as the economy adjusts its structure to the new prices. A typology of LDCs and the oil price increases in the 70's are used to illustrate the results of the model, which are compared with the actual increase in borrowing during the period. 相似文献
