Distribution-free test procedures in two-way layouts; a concept of rank-interaction

Summary  In this paper the concept of 'rank-interaction' is introduced and a distribution-free method for testing against the presence of 'rank-interaction' is suggested in the case of a two-way layout (classification) with m (> 1) observations per cell. Roughly speaking rank-interaction can be understood as the phenomenon at which the ranks of the levels of some relevant variable are different for different classes of the other factor. The exact null distribution of the test statistic has been computed in some cases. The asymptotic distribution under the null hypothesis has been derived. A test suggested by J.V. B radley in his book 'Distribution-free Statistical Tests' [2] is discussed. In the opinion of the authors it is doubtful whether the asymptotic distribution of the test statistic under the null hypothesis, as given by B radley , is correct. The test of B radley was intended to be sensitive to the presence of interactions defined in the usual way and hence not only to 'rank-interaction'. The same applies to methods proposed by some other authors. We claim that situations exist where one should test against rank-interaction and not against the usual more general alternative.     

Status of Benefits Transfer in the United States and Canada: A Review

Benefits transfer refers to the use of existing benefit estimates in a different but similar context compared with the original study that generated the benefit estimates. Benefits transfer techniques include fixed value transfer, expert opinion and value estimator models. Although benefits transfer techniques are subject to a number of conceptual and empirical limitations, these techniques are widely applied by government agencies as input into economic assessments of public policies and projects.
Le concept d'estimation des avantages économiques par transposition de données connues s'applique à I'utilisation de données obtenues dans un certain contexte a un contexte distinct mais semblable par rapport à celui de l'étude originale. Il y a essentiellement trois variantes de cette démarche: à partir de valeurs fixes, de jugements experts ou de modèles estimateurs de valeurs. Bien que ces techniques soient exposées à un certain nombre de limites conceptuelles et empiriques, elles sont largement utilisées par les organismes gouvernementaux comme intrants pour l'évaluation economique de leurs programmes et de leurs projets.     

The inside effects of a strong external employer brand: how external perceptions can influence organizational absenteeism rates

In this study, we invoke a social identity and job resources perspective to investigate the impact of an organization’s internal and external employer brand images on employee absenteeism. Specifically, using workforce samples of 56 Belgian companies (n = 12670) and a second independent study sample (n = 4461), we assess the relative importance of the internal employer brand image (i.e. employee perceptions) and the external employer brand image (i.e. non-employee perceptions) in predicting the absenteeism rate in these organizations. Results show that corporate absenteeism decreases as internal (employee) views and external (non-employee) views of the organization decline. Results further show that the external employer brand image may be a more important driver of absenteeism than the internal employer brand image. Such results highlight that an organization’s external image may be a strong antecedent of important internal organizational behavior outcomes.     

Bye,bye financial repression,hello financial deepening: The anatomy of a financial boom

Since the conquest of hyperinflation, with the Real Plan, in 1994, the Brazilian financial system has grown from early infancy to late adolescence. We describe the process of maturing with emphasis on the defining features of the Brazilian financial system over the last 20 years: (1) stabilization and the subsequent financial crisis; (2) universality of banks; (3) market segmentation through public lending; (4) institutional improvement. Further paraphrasing Diaz-Alejandro (1985), we raise some hypotheses on why, this time, the financial boom has not (at least yet) turned into a financial crash.     

Modeling voter choice to predict the final outcome of two-stage elections

Most election forecasting research to date has been conducted in the context of single-round elections. However, more than 40 countries in the world employ a two-stage process, where actual voting data are available between the first and the second rounds to help politicians understand their position in relation to each other and to voter preferences and to help them predict the final outcome of the election. In this study we take advantage of the theoretical foundation on voter behavior from the political science literature and the recent methodological advances in choice modeling to develop a Nested Logit Factor Model of voter choice which we use to predict the final outcome of two stage elections and gain insights about the underlying political landscape. We apply the proposed model to data from the first stage and predict the final outcome of two stage elections based on the inferences made from the first stage results. We demonstrate how our proposed model can help politicians understand their competitive position immediately after the first round of actual voting and test its predictive accuracy in the run-off election across 11 different state governorship elections.     

Organizational strategy and resource allocation for technological turnaround

Abstract
A major issue for organizations planning for technological turnaround concerns the question of how to internalize the new technology. This article reports the findings of an exploratory research that addressed this problem. A multiple case study approach has been used to study and analyze the different strategies and organizational approaches to absorb alien technologies (in-house development, intercompany co-operation, purchase of technology, contract research, joint-venture, acquisition). On the basis of the results, a propositional framework has been developed which offers managers a perspective to develop a strategy with respect to the appropriate organizational design to 'de-mature' technologically mature business units.     

Critical issues facing R&D managers in China

R&D managers in China experienced significant changes in the past decade, in particular because of Government policies of economic reform and opening to the outside world. These developments have brought about a number of rather specific R&D management issues and problems. The paper addresses the main problems faced by R&D managers in China. First, the current situation of R&D management in China is discussed, as well as the future developments. The paper then presents a case study of the CISRI (Central Iron & Steel Research Institute), a large comprehensive R&D organisation in Beijing. The analysis leads to the critical issues in CISRI's R&D management. After that, a further investigation is described into the trends of Chinese R&D management. The outcomes described focus on the future of R&D management in China as well as on the integration of Western R&D management theory in China. The paper concludes with the major issues and recommendations for the further development of R&D management in China.     

Changes in the second-moment properties of disaggregated capital flows

Using formal statistical tests, we detect (i) significant volatility increases for various types of capital flows for a period of changes in business cycle comovement among the G7 countries, and (ii) mixed evidence of changes in covariances and correlations with a set of macroeconomic variables.     

Wage inequality between and within groups: trade-induced or skill-bias technical change? Alternative age models for the UK

According to recent econometric studies, technical progress is the main source of the increasing skill premium in the UK and the US. However, it is not yet clear if technical progress is skill-bias or sector-bias and, most importantly, if the use of foreign technology has a role to play. By using alternative AGE models for the UK economy, I show that both trade-induced sector-bias technical change and skill-bias technical change can explain the stylised facts of the UK economy: tertiarisation; deindustrialisation; openness to foreign markets; increased skill premium; rise in wage inequality within the skilled; and unskilled labour groups. However, the model with sector-bias technical change due to trade performs better, because it can also explain two other important stylised facts: the decline of the wage rate of unskilled workers; and the large increase of imported capital goods.
