Horizontal Inequity and Vertical Redistribution

Inequality of post-tax income among pre-tax equals is evaluated andaggregated to form a global index of horizontal inequity in the income tax.The vertical action of the tax is captured by its inequality effect on averagebetween groups of pre-tax equals. Putting the two together, horizontalinequity measures loss of vertical performance. The identification problem,which has previously been thought insuperable, is addressed by a procedurevalidating the banding of income units into close equals groups. Thehorizontal and vertical effects of a major Spanish income tax reform areevaluated. Lines for future investigation are suggested.     

Manufacturing strategy-technology relationship among auto suppliers

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.     

On the Time Inconsistency of Optimal Monetary and Fiscal Policies with Many Consumer Goods*

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.     

The speed of adjustment in working capital requirement

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.     

Relationship lending and SME financing in the continental European bank-based system

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.     

Employees' overestimation of functional and relational service quality: A gap analysis

This study extends previous research on gap analysis of service quality by including not only functional service quality but also relational benefits. To this end, a field study was carried out in 36 hotels and 35 restaurants. The samples consisted of 213 employees and 657 customers. A questionnaire format was used to measure both functional and relational service quality, as well as customers' loyalty. When comparing employee and customer perceptions, gaps potentially range from ‘overestimation’ (employees' perceptions are greater than customers' perceptions) to ‘underestimation’ (customers' perceptions are greater than employees' perceptions). In general, the results indicated that the employees surveyed overestimated the service quality they offer to customers, although gaps were greater for certain service attributes than for others. In addition, some gaps were more related to customer loyalty than others. The findings also showed that employees' overestimation of relational benefits plays a moderating role, increasing the negative relationship between employees' overestimation of functional service quality and customers' loyalty. The theoretical and managerial implications of the results are discussed further in this paper.     

BAYESIAN INFERENCE METHODS FOR UNIVARIATE AND MULTIVARIATE GARCH MODELS: A SURVEY

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.     

Labour market outliers: Lessons from Portugal and Spain

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.     

What Should be Taught in Intermediate Macroeconomics?

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.     

Product Innovation in Resource‐Poor Environments: Three Research Streams

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.
