Sexual orientation and household decision making.: Same-sex couples' balance of power and labor supply choices.

This study estimates the effect of intra-household-bargaining on gay and lesbian couples' labor supplies, in order to determine how homosexual and heterosexual decision making compare, in a collective-household framework. Data from the 2000 US Census show that couples of all types exhibit a significant response to bargaining power shifts, as measured by age and non-labor-income differences between partners. Among gay, lesbian, and heterosexual cohabiting couples, a relatively young or rich partner has more bargaining power and supplies less labor, the opposite being true for his/her mate. Among married couples, the older spouse is instead more powerful, or the richer. No such patterns are found among same-sex roommates.     

Endogenous Minimum Participation in International Environmental Treaties

Many international treaties come into force only after a minimum number of countries have signed and ratified the treaty. Minimum participation constraints are particularly frequent in the case of environmental treaties dealing with global commons, where free-riding incentives are strong. Why do countries that know they have an incentive to free-ride accept to “tie their hands” through the introduction of a minimum participation constraint? This article addresses the above issues by modeling the formation of an international treaty as a three-stage non-cooperative coalition formation game. Both the equilibrium minimum participation constraint and the number of signatories—the coalition size—are determined. This article, by showing that a non-trivial partial coalition, sustained by a binding minimum participation constraint, forms at the equilibrium, explains the occurrence of minimum participation clauses in most international environmental agreements. It also analyses the endogenous equilibrium size of the minimum participation constraint.     

Identifying and Managing Creative Tasks in Collaborative IS Research Projects

Collaborative research projects require a high amount of creativity to create innovative results. Project management has to ensure that it recognizes and encourages creativity. This can be done successfully only if the nature of creative tasks is well understood. The current literature on creativity provides a well‐accepted model to characterize creativity. Based on a literature review and case study we transfer the findings into the context of collaborative information systems (IS) research projects and we evaluate their applicability. We derive specific criteria and characteristics for the identification of creative tasks, find a set of different task types, and provide implications directly usable by project managers.     

Capital indivisibility and tax competition: Are there too many business areas when some of them are empty?

In this paper, we propose a model where local jurisdictions must engage a development cost before competing for hosting a firm with uncertain preferences among possible sites. We first show that even an optimizing central planner managing all the jurisdictions develops more sites than there are plants to host. Doing so, he diversifies his supply and has a higher probability of hosting the firm. Then, we show that, if every jurisdiction is managed by a local government, there are more developed sites than with the central planner, which implies excess supply.     

Multi-item models for evaluating managerial and organizational resources in service firms

Services are the primary source of wealth in almost every nation around the world. Domestic competitiveness increasingly depends on the health of its service firms. Then understanding the source of competitive advantage for the case of service industry is a challenge that cannot be deferred. Resource-Based View literature gives sound evidences that intangible assets like managerial and organizational resources are the primary source of competitive advantage, especially in the service industry. However, the development of managerial tools for measuring and managing these resources remains as an open gap. In the last few years, some academic work has been devoted to develop intangible assets measurement devices. Nevertheless, these scales are either oriented towards manufacturing industry or do not take specifically into account the distinctive features of service delivery. This study replies the multi-item model proposed by Camisón (Manag Res 3(1):27–48, 2004) over a sample of 152 medium and large services companies. We have taken different tests to demonstrate validity and reliability of the scales. Results show that these scales may also be suitable for being used in all the types of service companies. However, some partial modifications should be done in order to give more relevance to soft managerial competences and to organizational human capital. This study was carried out as part of research project (reference GV2007-075) which has been subsidized by the “Valencian Government Programme Scientific Research and Technological Development Projects”.     

Linking owner–managers' personal sustainability behaviors and corporate practices in SMEs: The moderating roles of perceived advantages and environmental hostility

Drawing on managerial discretion and conflicting institutional logics literature, this study investigates the relation between the personal sustainability behaviors (PSB) of owner–managers and the corporate sustainability practices (CS practices) of SMEs. The research proposes a contingency model that assesses the moderating effects of perceived economic advantages and environmental hostility on this relationship. Based on linear hierarchical multiple regression analyses of a cross‐sectoral sample of French SMEs, the results suggest a positive influence of the manager's PSB on the SME's CS practices that appears to be differently moderated depending on the type of practice considered. The influence on environmental practices is fostered through the perception of economic advantages. The influence on workplace practices is only effective when the business environment is deemed benign and the influence on community practices is dampened by the perception of environmental hostility. Highlighting the trade‐off between the manager's personal values and the SME's economic constraints, these findings contribute to a better understanding of the critical antecedents of sustainability in small businesses.     

Size and diversity in VC syndicates and their impact on IPO performance

This paper investigates the impact of venture capital (VC) syndicate size and composition on the IPO and post-IPO performances of investee companies in an attempt to shed some light on the extent to which larger and more diverse syndicates are more likely to suffer from internal agency problems which might hinder the decision-making process and lead to less value added for their portfolio companies. The question is of great relevance because, while the vast majority of the empirical literature compares VC backed IPOs with non-VC backed ones, most VC funding is provided by syndicates of two or more financiers. We construct alternative measures of size as well as diversity based on several VC characteristics such as age, geographic location, type and affiliation of VC firms and find that larger and more diverse syndicates are associated with higher underpricing and lower valuation at the IPO date. Furthermore, we provide evidence that that diversity and size are negatively correlated to the long-term performance of the IPO firms and this finding is robust to several alternative measures of long-term performance.     

Asymmetric trading by insiders – comparing abnormal returns and earnings prediction in Spain and Australia

This paper examines whether the ‘external governance’ imposed by comparative financial accounting standards reduces the trading advantage of insiders. We do this by directly comparing insider trading returns and insider’s ability to predict future earnings from accruals in Spain and Australia. Results show higher excess returns and greater prediction of future earnings from conditioned insider trading in Australia that is then utilized by financial analysts to lower forecast errors – particularly in contrarian‐based accruals trading. Possible explanations include: (i) a high asymmetric quality for market‐based accruals, (ii) information transfer from informed insiders to uninformed insiders and financial analysts and (iii) a more timely dissemination of financial information in Spain through different ownership and governance structures.     

The speed of adjustment in working capital requirement

This paper analyzes the determinants of working capital requirement (WCR) and examines the speed with which firms adjust toward their target WCR. The findings indicate that firms adjust relatively quickly, which supports the hypothesis that current balance sheet items are easier to manipulate and could be changed quite easily, even in the short run. Moreover, we find that the speed of adjustment is not equal across all firms and varies according to their external finance constraints and their bargaining power. Firms with better access to external capital markets and greater bargaining power adjust faster due to their lower costs of adjustment.     

Regional differences in residential demand for very high bandwidth broadband internet in 2025

The future demand for data and the role of gigabit networks are central issues in the context of Next Generation Access (NGA) network roll-out. Based on a generic model, which allows to predict unconstrained future broadband demand in different regions and countries, the authors compare the results for Germany, the UK and the Flemish region, and discuss reasons for the different outcomes. The generic market potential model thereby allows to project the future demand for bandwidth from residential customers on the basis of applications and their bandwidth needs, user profiles and population structure on a household level. Despite a general trend towards an increasing need for broadband, there are clear differences. On the one hand, these point to the relevance of socio-demographic factors for broadband adoption. On the other hand, the relatively high proportion of refusals shows that there is still a need for further educational work on the part of public authorities and providers. Finally, it has to be stated, that our forecast relies on the assumption that connectivity and thus that the availability of area-wide gigabit capable broadband access does not represent a bottleneck.
