Recent theoretical models (Carlson, Fisher, and Giammarino, 2004) predict an association between the book-to-market equity ratio (BE/ME) and operating leverage in the cross-section. Consistent with these models, we find a positive association between BE/ME and the degree of operating leverage (DOL), between DOL and stock returns, and between DOL and systematic risk. Overall, our findings provide support for a risk-based explanation for the value premium that is consistent with existing theoretical models. The evolution of systematic risk associated with firm-level investment activity, rather than financial distress, seems to be the main determinant of the value premium. 相似文献

This article studies the performance of the high-order moment capital asset pricing model (CAPM) market models in emerging markets. We apply the cubic market model (4-moment CAPM) to 16 emerging market stock indices ranging from January 2010 to September 2015. Performance of the model is evaluated through the Fama and MacBeth’s two-step regression and through different corrections proposed in the literature, as well as generalized method of moments (GMM) estimation. According to Fama–MacBeth’s procedure, CAPM, the quadratic and cubic market models seem to be insignificant for the analyzed sample; however, the GMM estimation shows that quadratic model is valid for Indian, Polish, and Thai country indices, whereas cubic market model is accurate for Indian country index. 相似文献

Justifying ridge regression from a geometrical perspective is one of the main contributions of this paper. To the best of our knowledge, this question has not been treated previously. This paper shows that ridge regression is a particular case of raising procedures that provide greater flexibility by transforming the matrix X associated with the model. Thus, raising procedures, based on a geometrical idea of the vectorial space associated with the columns of matrix X , lead naturally to ridge regression and justify the presence of the well-known constant k on the main diagonal of matrix X ′ X . This paper also analyses and compares different alternatives to raising with respect to collinearity mitigation. The results are illustrated with an empirical application. 相似文献

Institutional environment influences the perceptions of desirability and feasibility, society’s social and cultural environment,
such as beliefs, values and attitudes, conditions behaviour and decisions made by individuals. This research evaluates the
influence of institutional environment on entrepreneurial intention using a comparative analysis of different attitudes among
university students in two countries: Portugal and Spain. In particular, this study aims to examine the perceptions of desirability,
feasibility and intention toward the creation of one’s own business and how that variables influence the entrepreneurial intention
as compared these two different institutional contexts. Results revealed difference among attitudes toward entrepreneurship
in both countries. With respect to the perception of feasibility, the majority of students in Extremadura (Spain) consider
that it is easier to create a business in nowadays than it was several decades ago. However, from the students of Beira Interior
(Portugal) consider that it is more difficult. Furthermore, in Extremadura, the entrepreneurial intention is higher than in
Beira Interior. 相似文献

The goal of this paper is to analyze the impact of annual earnings announcements on the market through the order flow data in addition to the usual transaction data. In this respect, examining order flow data can potentially reveal valuable information that is not available from transaction data. In fact, the data allow us to test hypotheses about asymmetric information and investor behavior and to test if the behavior varies with investor sophistication. In addition, the paper tries to identify the determinants of the impact on a firm's value using assumptions about investor behavior. 相似文献

In this paper, we test for the stationarity of European Union budget deficits over the period 1971–2006, using a panel of
thirteen member countries. Our testing strategy addresses two key concerns with regard to unit root panel data testing, namely
(1) the presence of cross-sectional dependence among the countries in the panel and (2) the identification of potential structural
breaks that might have occurred at different points in time. To address these concerns, we employ an AR-based bootstrap approach
that allows us to test the null hypothesis of joint stationarity with endogenously determined structural breaks. In contrast
to the existing literature, we find that the EU countries considered are characterised by fiscal stationarity over the full
sample period irrespective of us allowing for structural breaks. This conclusion also holds when analysing sub-periods based
on before and after the Maastricht treaty. 相似文献

How can a state with dysfunctional trade politics spur the negotiation of major free trade agreements (FTAs)? Using the case of Japan's participation in the trans-Pacific Partnership (TPP), we develop an analytical framework on FTA diffusion that takes into account multidimensional (economic, legal and political) competitive pressures, and the ability of states to act as pivots in triggering FTA cascades. We disaggregate the makeup of a pivotal state into two main components – capability and credibility – and underscore Japan's significant latent capabilities, but also its serious credibility shortcomings. The TPP's boost to Japan's credibility raised the possibility of significant economic, legal and political externalities for specific countries which responded by accelerating FTA initiatives that had long stalled: the trilateral China–Japan–Korea FTA, a 16-state East Asian FTA and the Japan–European Union trade negotiations. This study extends the theoretical frontier in policy diffusion studies by clarifying the combination of factors that allows some states, but not others, to activate the externalities behind the dissemination of defensive FTAs. 相似文献

Based on the knowledge-based view of the firm, this paper analyses how alternative configurations of technological relatedness in interfirm research and development (R&D) alliances influence specific types of product innovation. A longitudinal study of pharmaceutical firms provides support for the argument that complementary alliances contribute to the development of both radical and incremental innovation. Collaborating with partners that have similar technologies only enhances incremental innovation, although its impact is curvilinear. These evidences highlight the importance of designing a suitable portfolio of R&D alliances in order to develop different innovative competences. 相似文献

In this paper, we present estimates of the Human Development Index and the Gender-Related Development Index in the Autonomous Communities of Spain. Our case study of Spain, a developed country with clear gender and regional differences, demonstrates the importance of adjusting human development indices in accordance with gender discrimination and regional inequalities. We also show the significance of the income component in assessing the development level of women in countries like Spain, where lack of employment or low remuneration are the chief characteristics of women's inequality. Our analysis makes clear that the Gender-Related Human Development Index has limited applicability in developed countries; it also illustrates the need for alternative variables or models to assess inequality in those countries. 相似文献

Principal axis methods such as principal component analysis (PCA) and correspondence analysis (CA) are useful for identifying structures in data through interesting planar graphic displays. However, some kinds of data sets can be dealt alternatively with PCA or CA. This paper focuses on methods, such as PCA and CA, and on visual displays. Our aim is to illustrate the implications for a potential user of selecting either method, and its advantages and disadvantages, from an applied point of view. This is a matter covered broadly in textbooks and elsewhere considering theoretical arguments. Our purpose is to contribute to the comparison between these methods, over the same data set, in order to illustrate them for the practitioner. In the first part of this paper we present a novel analytical study of a binary matrix associated with a non-oriented axis-symmetric graph and show that CA outperforms standardized PCA for the reconstitution and visualization of such kind of graphs. In the second part we present a case using real data dealing with the distribution of employees in different economic sectors for the countries of the European Union, analyzed by means of standardized PCA and two-way CA, in order to see the differences between the two methods in practice. 相似文献
