We investigate the degree to which people in a shopping mall express other‐regarding behavior in the dictator game. Whereas many studies have attempted to increase the social distance between the dictator and experimenter and between the dictator and recipient, we attempt to minimize that social distance between random strangers by video recording the decisions, with the permission of the dictators, to display their image on the Internet. Offers made by dictators are high, relative to other experiments, and a nontrivial number give the entire experimental windfall away. However, a nontrivial number of people keep everything as well.  相似文献

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

In this paper, we study the effect of subsidised on-the-jobtraining, training for the unemployed and pure wage subsidieson job tenure. Correcting for selection biases, we find thateach of the labour market policies increases the length of jobtenure. Despite the sensitivity of the estimates to the parametricassumptions with respect to the unobservables, the effect ofsubsidised on-the-job training schemes is always found to besignificantly positive. Training programs for the unemployedand pure wage subsidies always have a positive, but statisticallynon-significant effect Our results provide some support forhuman capital theories as opposed to matching theories.  相似文献

Innovation is generally recognized as a major source of economic growth. R&D investments explicitly aim at generating innovations and creating knowledge. Since knowledge has certain public good properties, positive externalities are likely to exist. In this paper, we extend well-known concepts from the input-output literature (backward multipliers) to indicate at which commodities stimuli should be targeted to enhance R&D and its positive externalities in the economy as a whole. Next, we argue that there may also be negative externalities of R&D, due to increased prices. This issue can be studied by means of forward multipliers. Both concepts are applied to the United States, 1977-90.  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

The paper presents a conceptual model of an integrated management information system for municipal parks maintenance and operations. Research efforts in management information systems are presented in three categories: Business Research, Federally Sponsored Research, and Park and Recreation Systems Research. A case is made for further empirical research, the development of normative models, and evaluative criteria in an attempt to realize the full potential of electronic data processing in parks and recreation.  相似文献

A common premise in prior research is that trust increases over time in relationships. Through a meta‐analysis of 39 studies, we find that the bivariate correlation between trust and relationship duration (1) is on average positive and small, and (2) varies significantly across studies indicating the presence of unobserved moderators. We therefore build a theoretical framework to specify four different mechanisms—initial bias correction, change in relationship value, identification, and trust‐based selection—that may affect the development of trust. We then argue that the relative strength of these mechanisms should influence whether trust increases, remains constant, or decreases over time. © 2013 The Authors.

GARCH-type models have been very successful in describing the volatility dynamics of financial return series for short periods of time. However, the time-varying behavior of investors, for example, may cause the structure of volatility to change and the assumption of stationarity is no longer plausible. To deal with this issue, the current paper proposes a conditional volatility model with time-varying coefficients based on a multinomial switching mechanism. By giving more weight to either the persistence or shock term in a GARCH model, conditional on their relative ability to forecast a benchmark volatility measure, the switching reinforces the persistent nature of the GARCH model. The estimation of this benchmark volatility targeting or BVT-GARCH model for Dow 30 stocks indicates that the switching model is able to outperform a number of relevant GARCH setups, both in- and out-of-sample, also without any informational advantages.  相似文献
