This paper compares trading costs for institutional investors subject to liquidity shocks, in auction and dealer markets. The batch auction restricts the institutions' ability to exploit informational advantages because of competition between institutions when they simultaneously submit orders. This competition lowers aggregate trading costs. In the dealership market, competition between traders is absent but private information is revealed by observing the flow of successive orders and so reduces aggregate trading costs. We analyse the relative effects on trading costs of competition and information revelation in the two systems and derive a parameter inequality which determines which system has lower costs.  相似文献

For the last four decades much of the world's most advanced technical resources have been devoted to military systems; but with the end of the Cold War economic and technical resources are being freed to yield the so-called 'peace dividend'. This promotes the possibility of a more ethical orientation to many information technologists' work, and also represents the chance to argue for, and develop, more socially useful and responsible applications of computer technology, in accordance with the development of professional ideals and standards within the computing industry.

In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm-produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support.  相似文献

We examine the neglected area of internationalisation by VCs. Using a representative sample of 195 VCs, we show that the decision of a European VC firm to invest internationally is driven by its human resources. Having more VC executives in general and more VC executives with previous international experience in specific, results in a higher probability of investing internationally. In contrast, more VC executives with experience in the VC industry or with an engineering background lead to a higher probability of remaining domestic.  相似文献

This article uses a novel experimental approach to measure consumer willingness to pay (WTP) for wine attributes. We invited customers of a local supermarket who had selected a bottle of wine to purchase to participate in a valuation experiment. Integrating their original wine choice into the experiment, each participant evaluated six alternative wines, generating a rich set of data on willingness to pay and consumer characteristics. The data from the experiment allow us to compare standard shelf price‐based wine attribute valuation estimates with estimates using WTP data and an increasing amount of information about individual consumers. The full model employs individual fixed effects to estimate WTP parameters without bias from consumer sorting or supply side influences. Our WTP estimates for wine attributes differ markedly from previous attribute value estimates. Consumers in our sample display clear and stable preferences for wine varieties, but less clear preferences for appellations. Our results suggest caution is needed in using market prices to estimate parameters of the consumer valuation function for product attributes.  相似文献

Despite the numerous research endeavors aimed at investigating tourists’ preferences and motivations, it remains very difficult for practitioners to utilize the results of traditional association rule mining methods in tourism management. This research presents a new approach that extends the capability of the association rules technique to contrast targeted association rules with the aim of capturing the changes and trends in outbound tourism. Using datasets collected from five large-scale domestic tourism surveys of Hong Kong residents on outbound pleasure travel, both positive and negative contrasts are identified, thus enabling practitioners and policymakers to make appropriate decisions and develop more appropriate tourism products.  相似文献

Climate and ecosystem changes, economic and policy imperatives, food system pressures, and multiple societal expectations pose complex challenges for sustainable farming. A key problem is determining an effective and efficient approach to enable innovation in complex, multi-stakeholder settings. One approach currently receiving much policy attention and investment in the EU is ‘Living Labs’ which bring together public and private stakeholders to co-create, validate, and test new services, business ideas, markets and technologies. However, the analysis, monitoring and evaluation of Living Labs and their effectiveness and policy value in different contexts is limited. The AgriLink Living Labs were undertaken between 2018 and 2021 in Italy, Latvia, The Netherlands, Norway, Romania and Spain to co-create innovation support for improving agricultural sustainability. Our evaluation suggests that four inter-related critical conditions are needed for the success of Living Labs. These relate to the complexity of the challenge, the enabling environment, the proficient facilitation and the energy to move. These conditions influence the functioning of the Living Lab and we discuss the implications for policymakers and practitioners for the deployment of Living Labs in agricultural settings.  相似文献

The Hawaiian archipelago was the last major land area on the planet to be settled, with Polynesians making the long voyage just under a millennium ago. Building on new archaeological and historical research, the lecture provides an overview of the economic and political history of Hawai‘i from the first Polynesian settlements in the thirteen century through U.S. colonisation and statehood. The analysis considers how the political and economic institutions that emerged and evolved in Hawai‘i during its centuries of global isolation changed in response to Hawai‘i's post-1778 integration into a new world of global markets and colonial politics.  相似文献

Prior literature finds that information is reflected in option markets before stock markets, but no study has explored whether option volume soon after market open has predictive power for intraday stock returns. Using novel intraday signed option-to-stock volume data, we find that a composite option trading score (OTS) in the first 30 min of market open predicts stock returns during the rest of the trading day. Such return predictability is greater for smaller stocks, stocks with higher idiosyncratic volatility, and stocks with higher bid–ask spreads relative to their options’ bid–ask spreads. Moreover, OTS is a significantly stronger predictor of intraday stock returns after overnight earnings announcements. The evidence suggests that option trading in the 30 min after the opening bell has predictive power for intraday stock returns.  相似文献
