This paper studies the market reaction to vertical mergers and explores the many rationales for vertical integration proposed in the industrial organization literature. Abnormal returns for vertical merger announcements are positive until the late 1990s, and turn negative afterward. Acquirers suffer most of the losses. We find support for the most fundamental insight in the industrial organization literature, namely, that vertical mergers generate the greatest value when undertaken in imperfectly competitive markets. We find some evidence to support ideas of asset and site specificity, that is, creating value when market exchange is difficult. We do not find support for information‐based or price uncertainty theories. 相似文献

In this study, we collect a unique data set of Spanish domestic equity funds for the period 1999–2006 to test the existence
of the well-known “smart money” effect. Our focus is to test whether superior performance follows fund flows, demonstrating
investor skills, and whether the results are robust for aggregate portfolio analysis and for individual fund analysis. Empirical
evidence shows that investor abilities reported by aggregate portfolio analysis are not very evident from a fund-level perspective.
This study provides two major contributions to the literature: the separate consideration of purchases and redemptions, and
the proposal of a “smart investor” effect which considers investor movements instead of traditional money flows. Results show
that investors’ selling decisions are less smart than their buying decisions and that investors, as individuals, are not significantly
smarter than money. 相似文献

In this work we compare the interest rate forecasting performance of a broad class of linear models. The models are estimated through a MCMC procedure with data from the US and Brazilian markets. We show that a simple parametric specification has the best predictive power, but it does not outperform the random walk. We also find that macroeconomic variables and no-arbitrage conditions have little effect to improve the out-of-sample fit, while a financial variable (Stock Index) increases the forecasting accuracy. 相似文献

Objections to child labour range from its creating unfair trade advantage to its infringing children's human rights. Analysis of the responsibilities of various parties implicated in the use of child labour can lead to identifying stages in a cumulative ethical approach which is not self-defeating. The author is an economist who has recently completed his MBA at London Business School. 相似文献

The contingent perspective in strategic human resource management maintains that it is necessary to observe the interaction between human resource practices by encouraging external and internal labour flexibility. An issue still to be resolved is whether this fit leads to a complementary or substitute effect on firm performance. In order to contribute to this debate, we examine how the relationship between external labour flexibility and firm performance is moderated by the degree of internal labour flexibility. To do this, we use the Survey on Business Strategies of the Ministry of Industry, Tourism and Trade on a sample of 1,403 Spanish industrial firms. The results show the existence of a substitute effect between the two types of labour flexibility. Using them simultaneously does not lead to greater benefits for firms. 相似文献

The sector of Information and Communication Technologies (ICT) is one of the key instruments for the development of an economy. The literature emphasizes its capacity for both increasing productivity and generating new sources of income and wealth (5 and 20 among others). Traditionally studies on the ICT sector have focused on the analysis of its economic impact, but not on its capacity as a “bridge” for information and knowledge flows across the economic network. Following Burt's approach (1992) on structural holes, the organization of the economic network defines where and for whom new opportunities lie. The structural hole methodology allows to analyze the capacity of the ICT sector as an enabler of technological diffusion and innovation. The results show that the European ICT sector not only is important for its intermediary role in the flow of information across the economic network, but also for its low level of dependency on other sectors. 相似文献

This paper studies the effect of trade liberalization on inequality. We develop a theoretical framework that generates economy-wide distributions of wealth and income for different levels of trade protection. The model unambiguously determines the effect of liberalization on inequality; and rationalizes why larger inequality can be the outcome of a welfare enhancing policy, as households reduce their buffer savings when liberalization lowers the price of food. The framework reconciles the increase in inequality, the fall in the value of land, and farmers’ opposition to freer trade, that have featured in different liberalization episodes. We also present empirical support for the model’s predictions. 相似文献

Financial and non–financial information are developing issues in the NPO field. Countries such as Canada, the UK, the USA and Spain have recently updated their accounting systems for NPOs through the implementation of full accrual basis to enhance their accountability and the usefulness of accounting information for decision–making purposes. The information provided by accrual accounting will be incomplete until performance indicators are developed. The performance indicators are essential for making budgets, for planning and forecasting, for evaluating the financial needs, for carrying out benchmarking with other NPOs or governmental entities, and for explaining the welfare activities realised to donors. 相似文献

Nowadays the European Universities are worried about how to adapt higher education to the new European Higher Education Area,
as proposed in the Bologna Magna Charta Universitatum of 1998, and signed by 32 European Education Ministers. One of the key
points in this higher education reform was the introduction of new Master’s level curricula. These Masters will look for the
professional specialization and they will have to be adapted to the specific skills demanded by the society. This paper presents
the results from a cooperation project – funded by the AECI (International Cooperation Spanish Agency) and developed between
the University of Seville (Spain) and the Catholic University of Asuncion (Paraguay) – by about the planning of a new master’s
level curriculum in digital signal processing (DSP) area, taking into account the Bologna principles and the conclusions obtained
by the Career Space Consortium. A scientific method from social science, known as concept mapping techniques, was used to
perform this planning. Basically, the idea of concept mapping consists of compiling the opinion from actors belonging to different
environments (lecturers, researchers, workers, businessmen, etc.) related to DSP applications. The compiled data were statistically
computed to cluster the opinions of the different agents. The result will be a master’s level curricula adapted to the environment
requirements and the social settings. 相似文献

The ‘managerial’ and the ‘contractual’ theories of the firm imply different causes and consequences for the relationship between ownership and performance of firms. This paper provides a test of the two conflicting theories, using ownership and performance data from a sample of Spanish family- and non-family-controlled firms. We find evidence in support of the contractual theory of the firm, according to which firms choose their ownership structure maximizing economic value, net of contractual costs. 相似文献
