We emphasize the role of accounting policies, and their audit, in an earnings management setting. We use a two–period agency in which three frictions interact: the agent privately observes action (or effort) supply and output, and the initial contract is subject to renegotiation. This creates a setting in which both players' behavior is of concern, and, importantly, information rationing is efficient. Moreover, this information rationing is directly interpretable as being produced by an accounting policy whose application is ensured by an auditor. 相似文献

Based on different contractual forms and their associated degrees of organizational integration, a typology of strategies for technology acquisition (sourcing) is constructed. Based on a sample of corporations in Europe, Japan and US, it is shown that external acquisition of technology through various strategies increases in importance in general. Product case studies further show that external acquisition of technology is associated with technology diversification into increasingly costly new technologies. As a result corporations become multi-technological ('multech'). At the same time quasi-integrated corporate systems of innovation arise in which in-house R&D is managed together with a mix of strategies for external acquisition of technology, using various contractual forms. This presents new challenges to traditional in-house R&D management. Technology diversification is moreover shown to be associated with growth of sales as well as with growth of R&D expenditures. A high level of external technology acquisition presents risks that ought to lead companies to consider technology based product diversification. 相似文献

In recent years a growing stream of research has examined the relationships between structural characteristics of regions and their levels of new firm formation. This empirical study aims at supplementing such findings with analyses that include other forms of business dynamics, and also the possible well-being effects of such dynamics. From a unique and comprehensive data set that tracks all births, deaths, expansions, and contractions of commercial business establishments in Sweden 1985–89, six groups of regions with different patterns of dynamics are extracted by means of cluster analysis. The clusters' structural characteristics and their development of economic well-being are also compared. The results suggesta) that the patterns of business dynamics are contingent on the structural characteristics of regions,b) that high formation and turnover of establishments are associated with a relative increase in economic well-being, andc) that small, autonomous firms have a vital role in this process. 相似文献

A bstract . Even the most passionate defenders of free trade, such as Mises and Rothbard, claim that trade cannot occur under conditions of strict homogeneity of land, labor, and capital. We show that specialization, trade, and the division of labor can emerge even when resources are initially homogenous, due to "natural heterogeneity," economies of scale, and learning. 相似文献

Simple models of local government behavior predict equal effects of private income and unconditional federal grants on local
government expenditures. Numerous empirical analyses, however, find that the effect of grants is larger than the income effect.
We argue that this flypaper effect may be a result of weak political leaderships in multi–issue and multi–party decision–making
environments. In multi–issue institutions, a strong political leadership may reduce inefficiency due to interest group influence
and inter–party bargaining in the local council. Utilizing data for Norwegian local governments in the 1930s, we find that
political strength reduces the size of the flypaper effect. When the local council consists of only one political party, we
cannot reject absence of a flypaper effect, while the flypaper effect is large in fragmented local councils.

Summary We study the effects of introducing a feasible insurance market into the spatial separation model of money described in Mitsui and Watanabe (1989). We show that the insurance contract may or may not drive out money. We also show that, depending on the degree of risk aversion, the additional market can reduce welfare for all agents, increase welfare for all agents, or increase welfare for some agents and reduce it for others.The authors would like to thank Ed Green, Preston Miller, Ed Prescott and Neil Wallace for valuable comments. 相似文献

Modern information and microelectronic technology can be used to improve road traffic. The aim of this study is to create scenarios on how new information systems for improved road traffic can evolve. What are the driving forces? Who can act? Who can benefit? What are the social impacts?Through the use of a Delphi panel of professionals, researchers, and informed generalists, we have gathered impulses for the scenarios on how information technology, communication means, and control systems can reshape future road traffic. The issue studied is how this “Road Transport Informatics” (RTI) will evolve. 相似文献

How Often to Sample a Continuous-Time Process in the Presence of Market Microstructure Noise 总被引:13,自引:0,他引:13
In theory, the sum of squares of log returns sampled at highfrequency estimates their variance. When market microstructurenoise is present but unaccounted for, however, we show thatthe optimal sampling frequency is finite and derives its closed-formexpression. But even with optimal sampling, using say 5-minreturns when transactions are recorded every second, a vastamount of data is discarded, in contradiction to basic statisticalprinciples. We demonstrate that modeling the noise and usingall the data is a better solution, even if one misspecifiesthe noise distribution. So the answer is: sample as often aspossible. 相似文献

The literature on trade liberalization and environment has not yet considered federal structures. In this paper, we show how the design of environmental policy in a federal system has implications for the effects of trade reform. Trade liberalization leads to a decline in pollution taxes, regardless of whether pollution taxes are set at the federal (centralized) or local (decentralized) level, and it increases social welfare. The effect under a decentralized system is smaller than if these taxes are set by the federal government, and pollution emissions therefore decline in this case. Moreover, majority bias interacts with trade liberalization if federal taxes are used. 相似文献
