We use eSports data to construct an empirical model to measure the effect of diversity on team performance. Different kinds of diversities are considered, diversity of culture, diversity of language and diversity of skill. Our main results are that cultural diversity is beneficial for team performance: the absence of diversity reduces performance by 30%. However, language and experience diversity negatively affect results. Taking the difference in the results into account, we conclude that firms should not thoughtlessly maximize team diversity: different kinds of diversity have different integration and communication costs. 相似文献

This paper considers an alternative approachto surface water quality management whensociety is faced with the need to reduce waterpollution in a region with a complicatedregulatory environment. The paper is focusedon a specific kind of negotiation betweenpolluters and an authority, leading toresolution of the problem when there is theinformation asymmetry between the authorityand the polluters, i.e., the true pollutionabatement costs are known to the pollutersonly. This paper reports a laboratory experimentalcase prepared at the Department ofEnvironmental Economics, the University ofEconomics in Prague. The comparison withtheoretical computed first-best results underconditions of full information is included.Political and economic aspects of thesuggested approach are also discussed. 相似文献

This cross-section study of a sample of 278 firms from the COMPUSTAT II database explores the relationship between a firm's profitability and other variables, notably its own R & D capital, knowledge and market spillovers and appropriability. The proxy for knowledge spillovers is based on technological distance. Market spillovers are based on a patent input-output matrix. Both spillover proxies combine information on R & D expenditures and patent counts.The results do not reject the hypothesis that R & D has a direct, positive effect on profitability, especially in industries with effective patent protection. Information spillovers affect profits negatively, market spillovers positively. 相似文献

In this paper, we ask what the effects of migration and remittances are on land tenure, agriculture and forests, based on empirical evidence from four rural communities in Guatemala. Our results suggest that remittances improve migrant families' access to agricultural land which – depending on the context – fosters more equitable local land distribution patterns or land concentration by migrant families. Changes in the political economy of the country also combine to stimulate these patterns, while remittances contribute to secure land rights held by migrant households. But even though migrant households are acquiring more land, the trend does not change the traditional pattern of land distribution in the country. Regarding forests, significant changes were not observed in two of the communities, while in one we observed forest decline and in the last, forest recovery. A trend away from reliance on the land for survival results in forest recovery. 相似文献

(12764) Petr Janský Marek Šedivý Tax treaties between countries influence how much tax revenues governments receive from multinational enterprises. These treaties often reduce the withholding tax rates on outgoing dividend and interest payments. We provide illustrative estimates of costs for these two taxes for 14 developing countries in sub‐Saharan Africa and Asia in a first multi‐country comparison of this kind. These might be overestimates because we assume that foreign direct investments are not influenced by the tax treaties. We estimate that the highest potential tax revenue losses are within hundreds of millions US$ and around 0.1% of GDP, with Philippines incurring the highest losses both in US$ and relative to GDP. We also find that around 95% of the losses is due to dividends and that only four investor countries—Japan, Netherlands, Switzerland and Singapore—are together responsible for more than half of the losses. We discuss the limitations of these estimates and how future research could improve their quality as well as coverage. 相似文献

This study examines the environmental policy mix of tradable emission permits and emission taxes in a duopoly model with a consumer‐friendly firm. We analyse the interplay of the two policies and the welfare consequences in the presence of excess burden of taxation. We show that an emission tax can be redundant when both the excess burden of taxation and the degree of consumer friendliness are insignificant. However, when the excess burden of taxation is significant, tradable permits policy with tax treatment should be applied to enhance welfare in the presence of a consumer‐friendly firm. Finally, under the tax revenue‐neutral case where the excess burden of taxation does not matter, the environmental policy mix is also efficient if the degree of consumer friendliness is sufficiently high. 相似文献
