This study compared intergenerational earnings mobility in Singapore and the United States by replicating the sample criteria in the Singapore National Youth Survey on the U.S. Panel Study of Income Dynamics. The mean estimated earnings elasticities are almost identical: 0.26 in Singapore and 0.28 in the United States. Transformed to 0.44 and 0.47 respectively to reflect permanent status, mobility in the two countries is moderately low compared internationally. The finding of similar mobility is not surprising given that the two countries have similar economic realities, welfare systems, education regimes, and labor structures. Policy makers face the daunting challenge of overcoming immobility and inequality while maintaining global competitiveness. 相似文献

A growing number of studies and evidence from industries suggest that, besides managing the relationship with its suppliers, a buyer needs to proactively manage the relationships between those suppliers. In a buyer–supplier–supplier relationship triad, the buyer, as the contracting entity, influences the suppliers’ behaviors and the relationship between them. By considering the relationships in such a triad, we are able to gain a richer and more realistic perspective of buyer–supplier relationships. In this study, our goal is to examine supplier–supplier relationships in buyer–supplier–supplier triads, focusing on how such relationships impact the supplier performance. We frame the supplier–supplier relationship as co-opetition—one in which competing suppliers work together to meet the buyer's requirements. We investigate the role of the buyer on such relationships, and how the buyer and co-opetitive supplier–supplier relationships affect supplier performance. We find mixed empirical support for our hypotheses. However, we are able to demonstrate the dynamics of supplier–supplier co-opetition in the buyer–supplier–supplier triad. We point out the need for further studies in this area. 相似文献

Potential benefits from international diversification depend upon the stability in stock market relationships. Using monthly data of 11 international stock markets, this paper examines the stability in stock market relationships across month of the year and across different holding intervals. Empirical results show that the correlation structure is more stable than the covariance structure. While empirical evidence supports the hypothesis that the correlation structure is very stable across different holding intervals, the empirical support for the stability in correlation structure across month of the year is much weaker. 相似文献

In this paper, we study a (weak) vector equilibrium principle with capacity constraints of arcs and common arcs in some different paths. We obtain some necessary and sufficient conditions for a (weak) vector minimum cost flow. By virtue of a (weak) Δ-equilibrium principle, we also derive some necessary and sufficient conditions for a weak vector equilibrium flow. 相似文献

There is a compelling need to improve the relationship between managers in marketing and sales departments. This paper argues
that one critical way of enhancing individual managers’ perceptions of relationship effectiveness between these departments
is to view the issue as a matter of justice and suggests that perceived marketing–sales relationship effectiveness is positively
influenced by managers’ perceptions of organizational justice. Furthermore, it proposes that interfunctional communication
has the potential to enhance the proposed positive effects of justice and hence needs to be considered and effectively managed
when looking at marketing–sales relationship effectiveness. Data drawn from a survey of 203 marketing and sales managers in
38 consumer packaged goods companies are used to empirically test these predictions. The authors find that perceived sales–marketing
relationship effectiveness is influenced by perceptions of distributive, procedural and interactional justice. Greater interfunctional
communication is found to further enhance the positive effects of distributive and procedural justice on perceived relationship
effectiveness, but it does not contribute to the already strong positive effects of interactional justice. Furthermore, results
reveal important differences in the effects of justice on perceived relationship effectiveness across the marketing and sales
departments. 相似文献

While the literature shows that perks can affect firm values positively or negatively, we argue that firms with higher perks are more likely to be associated with a lower quality of financial reporting, which, in turn, can affect the informativeness of stock prices. Based on hand-collected data on perks from Chinese listed firms, we find that firms with lower perks are associated with higher informativeness of stock prices (or lower R-square). Moreover, the positive association between perks and R-square is shown to be weaker for firms with higher financial reporting quality through audit and earnings quality measures. 相似文献

Empirical evidence suggests that most firms operate in imperfectly competitive markets. We develop a search-matching model between wholesalers and retailers. Firms face search costs and form long-term relationships. Price bargain results in both wholesaler and retailer mark ups, which depend on firms' relative bargaining power. We simulate the general equilibrium model and explore the role of product market search frictions for business cycles. We conclude from the simulation exercise that incorporating product market search structure and shocks improve the standard real business cycle model to reproduce US business cycle fluctuations. 相似文献

Zimmer (‘The role of copulas in the housing crisis’, Review of Economics and Statistics 2012; 94 : 607–620) provides an interesting case study of the pitfalls of using parametric copulas to understand the US housing crisis in the latter part of 2000s. The original study by Zimmer (2012) employs a finite‐mixture copula to illustrate that the symmetry of the Gaussian copula may not be tenable, especially for US housing price data during the time period from 1975:Q2 to 2009:Q1. We undertake a replication of his study in a wide sense. First, we replicate the study by incorporating revised data and then extending the dataset to include the most recent data. Second, we implement a nonparametric copula estimator recently proposed by Racine (‘Mixed data kernel copulas’, Empirical Economics forthcoming) to the parametrically filtered data used in Zimmer (2012). Our replication finds that the application of the nonparametric copula to the same and extended filtered data provides an alternative flexible specification for copulas. However, the overall cautionary message of the flexible‐form copula espoused in Zimmer (2012) remains. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
