This paper studies optimal auction design when the seller can affect the buyers? valuations through an unobservable ex ante investment. The key insight is that the optimal mechanism may have the seller play a mixed investment strategy so as to create correlation between the buyers? otherwise (conditionally) independent valuations. Assuming that the seller announces the mechanism before investing, the paper establishes conditions on the investment technology so that a mechanism exists which leaves buyers no information rent and leaves the seller indifferent between his investments. Under these conditions, the seller can, in fact, extract the first best surplus almost fully. 相似文献

AbstractThis study identifies a gap in research concerning how small and medium-sized enterprises (SMEs) can benefit from pursuing locally (rather than globally) oriented internationalization strategies. Becoming overly dependent on one single foreign market could potentially reduce the inflow and diversity of new knowledge that can serve as input for new product development. This study discusses how this risk can be minimized. In this endeavour we create a theoretical model that investigates how the local sales concentration and relationship-specific commitment of SMEs relates to new product development. To do this we draw on the behavioural internationalization process framework. The theoretical model is tested on an effective sample of 188 Swedish SMEs. The results show that relationship-specific commitment mediates the effect of local sales concentration on new product development. The implication is that investments which enable collaboration in important business relationships are crucial requisites for keeping firms innovative and in pace with market fluctuations. The findings thus contribute to international business literature by showing that a local market scope of operations combined with a relationship orientation are beneficial for new product development in international SMEs. 相似文献

This study examines the private consumption benefits of sports attendance using revealed and stated preference data from 28 Football Bundesliga teams across three divisions. Survey respondents were presented with positive (sporting success) and negative (management failure) scenarios and asked for the number of game trips if each scenario occurred. The results of a pooled random effects Poisson model show that travel costs and ticket price have a significant negative effect on the number of home game trips. The weighted consumer surplus per game trip including travel costs and ticket prices is €345. Consumer surplus per game trip was found to change by €41 (first division) and €98 (second and third division) if the positive scenario occurred and by €39 if the negative scenario occurred. 相似文献

The aim of this study is twofold. First, the determinants of economic growth are studied among a wide set of potential variables for the Spanish provinces (NUTS3). Among others, various types of private, public and human capital in the group of growth factors are included. Also, it is analysed whether Spanish provinces have converged in economic terms in recent decades. The second objective is to obtain cross-section and panel data parameter estimates that are robust to model specification. For this purpose, a Bayesian Model Averaging (BMA) approach is used. Bayesian methodology constructs parameter estimates as a weighted average of linear regression estimates for every possible combination of included variables. The weight of each regression estimate is given by the posterior probability of each model. 相似文献

This paper considers the assignment of tradable permits—representing property rights of an environmental good—to community members who are harmed by pollution generated by firms. These community members can in turn sell permits to polluters according to their personal preferences. For a special case with a sole household, market transactions between the household and polluters achieve an efficient pollution level. However, for a group of households, the decentralized market solution fails to yield social efficiency because of competitive consumption of the environmental goods. We design a revenue-sharing mechanism akin to unitization, under which market transactions also achieve efficient resource allocation. Importantly, in some cases, efficiency can be achieved even when regulators are ignorant of the private valuation of the environmental good. 相似文献

A technology assessment (TA) program was launched in Switzerland in 1991. One project in the series of pilot projects was meant to assess the impact of so-called LESIT technologies on energy consumption. (LESIT was a priority research program and a German acronym for power electronics, systems and information technology.) In this paper the institutional environment, applied methods and main results of the TA study are summarised. One of the questions that arose was whether it is reasonable to expect a high-tech engineering research program to serve any societal goals other than the more immediate technical and economic goals the research partners in university and industry are accustomed to follow. It was found that without special efforts this expectation was not realistic. Politically desirable goals are best served when enough emphasis, time, and money are given to the process of bringing together research partners from academia and industry who all have a (self-serving) interest in furthering the politically desirable goal and then support their collaboration. 相似文献

The Effect of Aggregation of Accounting Information via Segment Reporting on Accounting Conservatism
In a sample of U.S. multiple-segment firms, we document a negative association between aggregation via segment reporting and timely loss recognition. A higher level of aggregation, as reflected in a firm’s reported organizational structure (the definition and characteristics of its segments), causes a multiple-segment firm to exhibit less cross-segment variation in profitability than a matched control portfolio of single-segment firms. We find that firms that engage in more aggregation report accounting numbers that provide less timely information about economic losses. We also observe that firms that provide more disaggregated segment data subsequent to adopting SFAS 131 experienced an increase in timely loss recognition. This result implies that higher quality segment reporting leads to an increase in timely loss recognition, which, per extant research, is associated with better governance. Our results complement results in Berger and Hann [2003. The impact of SFAS No. 131 on information and monitoring. Journal of Accounting Research, 41, 163–223] that show a decline in inefficient internal-capital-market transfers subsequent to the adoption of SFAS 131. Overall, we provide evidence supporting Beyer, Cohen, Lys, and Walther’s [2010. The financial reporting environment: Review of the recent literature. Journal of Accounting and Economics, 50, 296–343] contention that accounting conservatism is, in part, a function of managers’ aggregation choices. 相似文献

EBCT measured coronary calcium is fast becoming a standard screening tool in asymptomatic patients with and without risk factors who apply for life insurance. Since atherosclerotic plaques become calcified as part of their natural history, the calcium score is an excellent measure of total atherosclerotic burden. Over the past 5 years, various clinical studies have confirmed the predictive value of the coronary calcium score for both soft (revascularization, MI) and hard (MI and sudden cardiac death) events incrementally and independently of traditional coronary risk factors identified by the Framingham Heart Study. Accurate assessment of cardiac mortality risk in asymptomatic applicants for life insurance should include both traditional risk factor assessments in combination with age and gender specific percentiles for coronary calcium. New data from both new and ongoing clinical trials will seek to further support the predictive value of coronary calcium scores as an independent and incremental predictor of hard cardiac events. 相似文献

The corporate charters of a sample of Mexican firms show that private firms often significantly enhance the legal protection offered to investors, but public firms rarely do so. We construct a model that endogenizes the degree of investor protection that firms provide, using as a springboard the assumption that legal regimes differ in their ability to enforce precisely filtering contracts that provide protection only in those cases where expropriation can occur. Our model generates predictions about the types of contracts that would be employed and the levels of investor protection that would prevail across different legal regimes in both private and public firms. 相似文献
