Entrepreneurs and the Process of Obtaining Resources   总被引:1,自引:2,他引:1  
This paper examines the process of how entrepreneurs assemble resources. In the model, the entrepreneur's challenge is to convince two complementary resource providers to commit their resources to a new venture. Before committing their resources, one of them needs to perform a costly evaluation. The entrepreneur has a problem with getting sufficient attention, because each provider has an incentive to wait and free-ride on the other's evaluation. For some parameters the entrepreneur solicits both partners with equal intensity ("knocking on every door"); for others, the entrepreneur always solicits the same partner ("pestering"). For many but not all parameter ranges, the process of assembling resources takes too much time relative to what is socially efficient. The model thus explores what factors facilitate or hinder the creation of new firms.  相似文献

Based on economic methodology we model an ecosystem with two species in predator–prey relationship: mice feed on grain and grain feeds on a resource. With optimizing behavior of individual organisms a short-run ecosystem equilibrium is defined and characterized that depends on the farmer's use of fertilizer and pesticide and on the mice population which, in turn, is affected by pesticides. In that way, a microfounded agricultural production function is derived. Linking a sequence of short-run ecosystem equilibria yields the growth function of the mice population which is thus derived rather than assumed. In each period the farmer harvests all grain in excess of some given amount of seed. If she maximizes her present-value profits, optimal farming is characterized by either using no pesticide or a moderate amount of pesticide or by applying a chattering control. Pest eradication is never optimal. On the other hand, if the farmer takes into account steady-state mice populations only, it may be optimal to eradicate mice or to use no or a moderate amount of pesticide depending on prices as well as on the shape of the grain production function which is determined by microparameters of grain reproduction.  相似文献

Abstract . Developing countries face an inconsistency between the need for more equitable distribution of income and wealth between classes and groups and the goals of an industrial relations system in which the trade unions have a systematic commitment to allied political parties to support them in exchange for some control over economic and social policy, or where unions compete with parties for popular support of certain social and political goals. This is designated as 'political unionism' in contradistinction to 'business unionism' where unions support any party whose overall strategy and objectives are most compatible. The analysis shows that ‘political unionism’ led, in Jamaica and in Trinidad and Tabago, to lags in growth which make industrial relations reform a necessity of an effective program of social change.  相似文献

Group decision-making: Head-count versus intensity of preference   总被引:1,自引:0,他引:1  
This paper puts forth a framework for reshaping the group decision-making process. The proposed framework extends from the usual one-issue-at-a-time decision-making to one that involves several related issues simultaneously. Weaknesses of the traditional majority voting mechanism are first identified, and then a different voting method that takes each individual voter's sentiment into account is discussed. Specifically, a decision-maker is asked to express his/her intensity of preference for the issues encountered. Three hierarchical structures—benefits, costs, and risks—are developed to evaluate the alternatives. Due to the nature of pairwise comparisons and synthesis, the proposed method is amenable to consensus building and has higher reliability and consistency. It can be used for candidate selection, e.g. governmental election, when a large population is involved. It is also effective for resource allocation and prioritization when a small group or business is concerned. We believe the proposed approach has potential for resolving deficiencies of the conventional voting mechanism, and can be applied to many real-world problems. Its implementation on the Internet is also discussed.  相似文献

Prior research has employed a number of methods to test for speculative bubbles in asset prices, including a method based on the concept of duration dependence. This study explores whether duration dependence tests for speculative bubbles are sensitive to specification decisions. Our results question the efficacy of using measures of duration dependence to test for speculative bubbles. In particular, we find that evidence of duration dependence is sensitive to the method of correcting for discrete observation of continuous duration, the use of value-weighted versus equally weighted portfolios, and the use of monthly versus weekly runs of abnormal returns.

This research responds to the attendant need for empirical evidence pertaining to how marketing affects firm performance. Using the Fama-French method, common in finance, and a leading marketplace measure of a brand’s financial equity value, the authors provide empirical evidence for the branding-shareholder value creation link. The results extend previous research by showing that strong brands not only deliver greater returns to stockholders than does a relevant benchmark but do so with less risk This finding holds even when market share and firm size are considered.

Current projects explore person-brands, resonance as a moderator of the brand meaning → brand strength connection, the types of relationships consumers form with brands, and dynamic processes of relationship development and evolution. She served for 9 years on the Harvard Business School faculty and 2 years as a visitor at Dartmouth College. She consults with a range of companies to inform her teaching, case development, and research.  相似文献

This study examines three trust-building processes and outcomes in sales manager-salesperson relationships. This study, based on a sample of more than 400 business-to-business salespeoples from a variety of industries, shows two trust-building processes (predictive and identification) to be significantly related to salesperson trust in the sales manager. Interpersonal trust was found to be most strongly related to shared values and respect. Trust was directly related to job satisfaction and relationalism, and indirectly related to organizational commitment and turnover intention. Thomas G.

The mitigation hierarchy (MH) is a prominent tool to help businesses achieve no net loss or net gain outcomes for biodiversity. Technological innovations offer benefits for business biodiversity management, yet the range and continued evolution of technologies creates a complex landscape that can be difficult to navigate. Using literature review, online surveys, and semi-structured interviews, we assess technologies that can improve application of the MH. We identify six categories (mobile survey, fixed survey, remote sensing, blockchain, data analysis, and enabling technologies) with high feasibility and/or relevance to (i) aid direct implementation of mitigation measures and (ii) enhance biodiversity surveys and monitoring, which feed into the design of interventions including avoidance and minimization measures. At the interface between development and biodiversity impacts, opportunities lie in businesses investing in technologies, capitalizing on synergies between technology groups, collaborating with conservation organizations to enhance institutional capacity, and developing practical solutions suited for widespread use.  相似文献
