Public procurement partnerships represent a new approach to conducting government acquisition. These partnerships are predicated on the notion that governments today simply lack the requisite knowledge, skills and financing to provide core public services and acquire sophisticated services, IT and knowledge development by themselves. Instead, governments need to enlist the collective energies of the governmental, business and non-profit (third) sectors. This research looks at the concept of public procurement partnerships in the United States and the major trends promoting their use. Two case examples of public procurement partnerships are presented; one from the perspective of a government partner, the other from the perspective of a private (third) sector partner. 相似文献

Pelikan (J Evol Econ 21:341–366, 2011) develops an interesting conceptual framework that adds to prior work on generalised Darwinism. Despite claims to the contrary
we show that it is similar to the approach developed by Hodgson and Knudsen (J Evol Econ 16(4):343–366, 2006a, J Econ Behav Organ 75(1):12–24, 2010a, b), Aldrich et al. (J Evol Econ 18(5):577–596, 2008) and others. Pelikan also mischaracterises the Hodgson–Knudsen position over Lamarckism. We show why the term is misleading
(rather than strictly wrong) when applied to social evolution. 相似文献

We use a laboratory experiment to study the extent to which investors’ choices are affected by limited loss deduction in income taxation. We first compare investment behavior in the no tax baseline to a tax control setting, in which the income from investments is taxed. We find that investors significantly reduce their risk-taking as predicted by theory. Next we compare the baseline investment choices to choices under three different types of income taxation. We observe that risk-taking is significantly increased with partial and with capped loss deduction, but is unaffected by a tax system that allows no loss deduction. Since in all these treatments the after tax outcomes of the prospects were identical, we conjecture that investors have a positively biased perception of partial and capped loss deduction that promotes their willingness to take risks. 相似文献

Within the standard Keynesian multiplier framework, extended by a micro-model of interactive formation of individual consumption
propensities, we demonstrate that socioeconomic interactions can lead to cyclical fluctuations in aggregate economic activity.
The underlying micro-model of direct interactions is a version of Alan Kirman’s generic opinion formation model, with an additional
feedback effect from macroscopic variables on the transition probabilities. Our model engenders cyclical fluctuations of economic
variables, despite the fact that neither the Keynesian multiplier model nor Kirman’s model does so on its own. 相似文献

Measuring volatility with the realized range 总被引:1,自引:0,他引:1
Realized variance, being the summation of squared intra-day returns, has quickly gained popularity as a measure of daily volatility. Following Parkinson [1980. The extreme value method for estimating the variance of the rate of return. Journal of Business 53, 61–65] we replace each squared intra-day return by the high–low range for that period to create a novel and more efficient estimator called the realized range. In addition, we suggest a bias-correction procedure to account for the effects of microstructure frictions based upon scaling the realized range with the average level of the daily range. Simulation experiments demonstrate that for plausible levels of non-trading and bid–ask bounce the realized range has a lower mean-squared error than the realized variance, including variants thereof that are robust to microstructure noise. Empirical analysis of the S&P500 index-futures and the S&P100 constituents confirms the potential of the realized range. 相似文献

This paper develops a contractarian theory of the state and the existence of redistribution. The existence of rules of redistribution is explained without any recourse to the risk-aversion of agents. No veil of ignorance is needed. This avoids obligational problems inherent in most other contractarian theories of justice. Hence, this paper departs from the standard legitimization of redistribution as fundamental insurance and interprets it as stemming from a principle of reciprocity in trade. Since this paper deals with an anarchic society, the implementation of redistributional rules is constrained by the assumption of self-enforcement. We show that this assumption changes the interpretation of the state: the state is characterized by a particular design of equilibrium strategies, not by the existence of enforcement agencies. 相似文献

A hierarchical model of collusion in local public works is presented. A local authority plans to undertake a project, delegating its construction to a construction firm. Both of them know the project's cost. However, the federal government decides whether to subsidize the project without knowing its cost. Therefore, the local authority and the constructor may agree to misreport their private information, in order to benefit from the allocation of federal grants. We show that different collusive behaviors may emerge. Then, we characterize the optimal federal grant policy. Finally, we investigate when constructing (shutting down) useless (valuable) projects is optimal. 相似文献

This article uses Australian panel data for the years 2001–2009 to estimate returns to general experience, job and occupational tenure. We pay particular attention to issues of unobserved heterogeneity bias in our estimations. We find that both general experience and occupational tenure have statistically and numerically significant effects on wage outcomes, even after controlling for unobserved heterogeneity. Job tenure on the other hand only seems to matter in OLS regressions that do not control for heterogeneity biases. Once these biases are controlled for, only a modest effect from job tenure remains. The inclusion of occupational tenure in the estimating equation tends to negate even this modest job tenure effect. The only exception to this is for workers in large organizations. For these workers a small but statistically significant effect from job tenure remains, even once we have controlled for heterogeneity and included occupational tenure in the estimating equation. The results reported in this article have implications for the various theories of the labour market that predict upward-sloping wage-job-tenure profiles. 相似文献

Several studies of innovative work practices show a positive link with firm performance and employees’ task involvement, organizational commitment and citizenship behaviours. One of the recent changes faced by firms is the introduction of Information and Communication Technologies (ICTs). Although several empirical studies analyse the links between ICT use, innovative work practices and firm performance, employee-level analyses are scarce. Using data from the European Working Condition Survey (EWCS), this article investigates the relationships between use of the Internet and computers and positive attitudes among employees (social support, job satisfaction, extra effort) in the European context. Our empirical results are based on data for more than 9500 employees from 16 European countries in 2005, and more than 14 000 in 2010. Among the different effects of ICT use, based on the results for the 2005, 2010 and the pooled 2005–2010 sample, and in a within-cohorts change analysis, we find that Internet use is positively related to employees’ job satisfaction and extra effort. We find that computer use is not related to employees’ behaviours. We find also that most of the innovative work practices considered are positively related to employees’ positive attitudes. 相似文献

It has been acknowledged that universities are key institutions in national and regional systems of innovation. This recognition has led to a rich stream of literature analysing the university–industry relationship. However, relatively little attention has been devoted to disaggregating the ‘industry’ side of this relationship and examining the costs and benefits to the disaggregated parties involved. In the present article, which draws on an analytical and empirical study from Scotland, it is suggested that it makes sense to distinguish between three kinds of firms in analysing the university–industry relationship: large national and international R&D-intensive firms, university spin-out firms, and established small- and medium-sized enterprises (SMEs) that have had little interaction with universities. The different costs and benefits facing these firms in their interactions with universities are analysed. It is concluded that the established SMEs confront relatively high costs in relating to universities. Finally, the policy implications are explored. 相似文献
