Each manufacturing plant has to develop its own path to success based on contingencies and on manufacturing practices links. On the basis of the latter, this paper tests the link between two of the most important manufacturing practices areas, manufacturing strategy (MS) and technology, without addressing causality or their combined effect on performance. This is done by selection fit, i.e. congruency adjustment. However, this paper goes beyond grouping both sets of practices in pairs, by using a more general selection view version, with practices from both sets related multidimensionally and subordinated by regression analysis to test for any congruent pattern. Regression results from a wide-ranging survey of auto supplier plants show that, in general, MS seems to have some kind of impact on technology, and that technology has some kind of influence on MS. In addition, a strong congruency between both practices areas is observed when using correlation. This suggests that when implementing or adjusting MS or technology, the other should also be considered; otherwise they may not operate effectively. 相似文献

In this paper, we study the time consistency of optimal policies in an environment where agents use cash to purchase many consumer goods and where those goods might be taxed at differential rates. Our main result is that optimal monetary and fiscal policies are, in general, time‐inconsistent, because the number of bond instruments is insufficient to influence all future fiscal decisions. However, there is one special case where optimal policies are time‐consistent, which is when differential tax rates across cash goods are optimally zero. 相似文献

This paper analyzes the determinants of working capital requirement (WCR) and examines the speed with which firms adjust toward their target WCR. The findings indicate that firms adjust relatively quickly, which supports the hypothesis that current balance sheet items are easier to manipulate and could be changed quite easily, even in the short run. Moreover, we find that the speed of adjustment is not equal across all firms and varies according to their external finance constraints and their bargaining power. Firms with better access to external capital markets and greater bargaining power adjust faster due to their lower costs of adjustment. 相似文献

Relationship lending and SME financing in the continental European bank-based system 总被引:2,自引:0,他引:2
This paper analyzes the relationship between banks and SMEs in the continental European bank-based system. We find that SMEs
with longer bank relationships have enhanced access to loans, but at the same time they bear a higher cost for their debt.
We also find that firms maintaining two bank relationships get the cheapest debt, which establishes a limit for the degree
of concentration of bank relationships. Our results also show that the existence of trust between firm and bank improves access
to financing and reduces the borrowing costs, whereas it increases the likelihood that guarantees will have to be provided.
As a consequence, it seems that a relationship based on trust is a better strategy to improve SMEs’ access to finance than
the establishment of longer or more concentrated relationships. 相似文献

This survey reviews the existing literature on the most relevant Bayesian inference methods for univariate and multivariate GARCH models. The advantages and drawbacks of each procedure are outlined as well as the advantages of the Bayesian approach versus classical procedures. The paper makes emphasis on recent Bayesian non‐parametric approaches for GARCH models that avoid imposing arbitrary parametric distributional assumptions. These novel approaches implicitly assume infinite mixture of Gaussian distributions on the standardized returns which have been shown to be more flexible and describe better the uncertainty about future volatilities. Finally, the survey presents an illustration using real data to show the flexibility and usefulness of the non‐parametric approach. 相似文献

Labour market outliers: Lessons from Portugal and Spain 总被引:1,自引:0,他引:1
Spain has the highest unemployment rate (22.2%) of any European Union country, Portugal one of the lowest (7.3%). Superficially, these countries share many labour market features: the toughest job security rules in the OECD, an apparently similar architecture of wage bargaining, and comparable generosity of their unemployment insurance systems, at least since 1989. We address the puzzle by examining Portuguese and Spanish labour market institutions, in particular job security, unemployment benefits and the system of wage bargaining. We then conduct empirical analysis of Spanish and Portuguese unemployment outflows and wage distributions, using micro data. We find differences in unemployment benefits (non-existent in Portugal until 1985, and less generous nowadays), differences in wage flexibility (wage floors by category established by collective agreements are set at a lower relative level in Portugal), and, in practice, higher firing costs in Spain. A key explanation of the difference in Portuguese and Spanish unemployment rates is the wage adjustment process. Generous benefit levels may have been necessary for the path Spanish unions took, but this was not the sole explanation of different wage setting in Spain and Portugal. 相似文献

A lack of consensus remains on what should form the theoretical core of the undergraduate intermediate macroeconomic course. In determining how to deal with the Keynesian/classical divide, instructors must decide whether to follow the modern approach of building macroeconomic relationships from micro foundations, or to use the traditional approach based on aggregate models of the macroeconomy. In this article, the authors discuss the advantages and shortcomings of each approach in the context of course objectives. Because there is significant heterogeneity in textbook coverage, the authors summarize some of the approaches taken in current intermediate-level textbooks, which should serve as a useful starting point for new instructors. The authors also discuss how each approach can be extended to analyze the recent recession in the United States. 相似文献

We explore the role and relevance of resource scarcity in product innovation. The literature tends to assume that the development of new products requires resource sufficiency for the process to be conducted systematically. But we are also taught that necessity is the mother of invention and that resource scarcity may be a trigger of innovation in adverse contexts. In this discussion, we organize the literature on product innovation in resource‐poor contexts in three streams. The paper contributes to a finer‐grained understanding of the role of scarcity in product innovation and suggests that creative approaches to scarcity may contribute to knowledge enrichment of product innovation theory and practice. 相似文献
