Stores 总被引:1,自引:0,他引:1
Summary There is scope and incentive for stores to endogenously arise in an exchange economy when agents possess different levels of bargaining power and coalition formation is costly. In the absence of stores, agents face a trading lottery where the expected outcome for an individual agent depends upon his relative bargaining strength. By setting appropriate, preannounced prices, a store can profitably offer relatively weak bargainers trading opportunities which they prefer to the trading lottery. While relatively weak bargainers are attracted to the store, relatively strong bargainers prefer the trading lottery to the store. Thus, the simultaneous existence of barter and mediated trade is explained.The work reported here was conceived while both authors were visiting the University of Southern California. We thank Martine Quinzii and two anonymous referees for helpful comments. 相似文献

This paper deals with remnants of neoclassical elements in Keynesian and post- Keynesian throught, and attempts to demonstrate that the elimination of these elements from our modes of thinking would not impoverish economic analysis as a means of solving real problems.In the Keynesian analysis the causation from investment to savings is exhibited in terms of income determination. When put in terms of a capital theory model, the vector of savings is represented in two ways: firstly, real savings, and secondly, counterpart real savings. The former coincides with the investment vector and the latter with the vector of consumption goods foregone for diverting resources towards equipment making. Thus the Keynesian causation in capital theory terms makes the concept of national savings as an independent variable redundant.The Robinsonian causation in a golden age with full employment and its reversal of direction in a steady state with non-employment are then considered. But in each of these, variables like rate of savings and output-capital ratio are found to be dormat variables. They are termed as null variables which, being of no account in both full-employment and unemployment situations, could, without loss, be deleted from the repertory of analytical tools. The Harrod formula of warranted rate of growth, when put in causal form, thus becomes a redundant portion of economics of growth. The real determinants of the growth rate and real wage rate on which the analysis of growth or of development should be based, are also depicted. 相似文献

ABSTRACT This study attempts to investigate the relationship between switching barriers and service recovery evaluation of consumers in Indian context. Empirical findings of the present study provided useful insights. The primary statistical techniques used in the study were correlation analysis and exploratory factor analysis. A total of 347 respondents completed the field survey, and the survey was conducted in Dehradun, Uttrakhand. It was found from the results of correlation analysis that compensation and promptness constructs had comparatively high correlation coefficients with overall service recovery evaluation in comparison to employee behavior construct. Another insightful finding of the study provided evidence for a significant relationship between service recovery evaluation and positive switching barriers, but at the same time there was no evidence for a relationship between service recovery evaluation and negative switching barriers. 相似文献

This paper describes the nature of equilibrium for a dynamic game between a monopolist and an entrant who adopts a learning strategy for cost reduction. The learning process is characterized as a continuous-time Poisson process where each success reduces a part of the entrant's cost difference with the incumbent. The entrant chooses a stream of expenditure after every success to control the instant probability of the next success. The techniques of semi-Markov decision processes are used to characterize equilibrium learning decisions at every stage, distribution of entry times, and the effects of subsidies, technical progress, etc. on pre-entry and post-entry learning strategies. 相似文献

The fragility of the CAPM has led to a resurgence of research that frequently uses trading strategies based on sorting procedures to uncover relations between firm characteristics (such as “value” or “glamour”) and equity returns. We examine the propensity of these strategies to generate statistically and economically significant profits due to our familiarity with the data. Under plausible assumptions, data snooping can account for up to 50 percent of the in‐sample relations between firm characteristics and returns uncovered using single (one‐way) sorts. The biases can be much larger if we simultaneously condition returns on two (or more) characteristics. 相似文献

This paper examines the impact of acquisitions on the subsequent innovation performance of acquiring firms in the chemicals industry. We distinguish between technological acquisitions, acquisitions in which technology is a component of the acquired firm's assets, and nontechnological acquisitions: acquisitions that do not involve a technological component. We develop a framework relating acquisitions to firm innovation performance and develop a set of measures for quantifying the technological inputs a firm obtains through acquisitions. We find that within technological acquisitions absolute size of the acquired knowledge base enhances innovation performance, while relative size of the acquired knowledge base reduces innovation output. The relatedness of acquired and acquiring knowledge bases has a nonlinear impact on innovation output. Nontechnological acquisitions do not have a significant effect on subsequent innovation output.

We seek to determine the causes and magnitudes of network externalities for the automated clearing house (ACH) electronic payments system. We construct an equilibrium model of customer and bank adoption of ACH. We structurally estimate the parameters of the model using an indirect inference procedure and panel data. The parameters are identified from exogenous variation in the adoption decisions of banks based outside the network and other factors. We find that most of the impediment to ACH adoption is from large customer fixed costs of adoption. Policies to provide moderate subsidies to customers and larger subsidies to banks for ACH adoption could increase welfare significantly. 相似文献

This paper aims to contribute to our understanding of the factors influencing South Asian entrepreneurial growth in Britain. It develops a multivariate model along the lines of small business economics but includes cultural and social variables. The theoretical model specified assumes that cultural factors have an augmenting effect on socio-economic factors. A distinction is also drawn between initial entrepreneurial characteristics and later expansion strategies used. The empirical model, based on the general-to-specific approach, can explain almost 60 per cent of entrepreneurial growth. The results suggest that moving away from a style of management based on immigrant culture has a positive impact on growth. This requires greater delegation of responsibilities to non-family employees. At the same time, strengthening links with the country of origin has a positive impact on growth. While the commitment to work hard at start-up is essential, human capital factors like the entrepreneur's educational attainment and employee training appear to be more crucial than financial resources in contributing to growth. 相似文献
