Collective Bargaining and Within-firm Wage Dispersion in Spain

This paper analyses the effect of collective bargaining on within‐firm wage dispersion for the case of Spain. What is relevant in the Spanish case is to compare the effect of the two basic levels of bargaining (firm and sector) on wage dispersion. By using the Oaxaca–Blinder decomposition, this paper concludes that collective agreements at firm level have a negative effect on wage dispersion. At the same time, firms that have signed these types of agreements show greater wage dispersion than those covered by agreements at the sector level, owing to the positive and compensating effect of firms’ and workers’ features.     

Offshoring technology innovation: A case study of rare-earth technology

Many US firms are improving their individual competitiveness by offshoring manufacturing operations, services and, increasingly, knowledge work. Although research to date has maintained that these practices are beneficial to the offshoring firm and national economies, by reducing costs and expanding markets, little is known about the longer term effect of offshoring on the rate of innovation of home economies. This paper suggests that offshoring practices have adverse effects on innovation at the national home base. The analysis uses patents in the rare-earth element industry, a high-tech area which is among those that have evolved the furthest towards outsourcing and relocation away from the US and to developing countries. Looking at the rare-earth industry can provide insights in identifying potential long term impacts of offshoring on innovation because many other US industries are likely to adopt similar offshoring strategies.     

Efficiency assessment of Portuguese municipalities using a conditional nonparametric approach

This paper assesses the efficiency of crop and livestock production in Colombia by using a sample of 1565 households. The study considers households located in different production systems which differ in geography, climate and soil types. These conditions affect technical efficiency and thus render analysis under the same production frontier as inadequate. For this reason, stochastic metafrontier techniques are preferred, allowing the estimation of technical efficiency within each production system and between production systems in relation to the sector as a whole. Results suggest that households in some production systems could be benefiting from better production conditions due to advantages in the availability of natural resources and climate as well as to more favorable socio-economic conditions. Additionally, we found that, in all systems, households with higher production have higher measures of technical efficiency. Thus, significant gains could be achieved in the sector through measures that contribute to improve the efficiency of households within their production systems and by policies that help reduce the technology gap in relation to the meta-frontier. These policies would bring positive impacts on the quality of life of small farmers and on the productivity of the sector.     

Measuring entrepreneurial quality in southern Europe

The main objective of this paper is working out an empirical methodology to measure the quality of the entrepreneur’s booster function, so that policy makers have an appropriate diagnosis of the qualities of entrepreneurs in their area. In this sense, two essential elements are the construction of an explanatory model, and the establishment of an entrepreneurial typology with respect to quality levels. This methodology is then applied to determine the quality level of entrepreneurs in Seville province (southern Spain), using Partial Least Squares estimation technique on a survey of 278 entrepreneurs from various activity sectors and with firms of different sizes.     

Opening the box: Comparing EU and US scientific output by scientific field

Recent reports suggest that, during the 1990s, the EU15 overcame the US in scientific output. This paper provides a comprehensive comparative analysis of the evolution of the EU15 and US scientific output and impact throughout the 1990s, looking at publications and impact trends by scientific field. Results show that changes in scientific production for the two blocks are driven by particular scientific fields which grew or declined at a fast rate during the decade. Throughout this period, the EU15 had eight fields of science, corresponding to a 13% of the total papers published, growing at a rate faster than 10% in relation to world average, while the US had only four fast growing fields, representing 6% of its total output. The situation was exactly reversed for the decline, with the US having more than doubled the number of scientific fields when compared to the EU15 declining at a rate faster than 10%. Despite this recent trend, the US maintains a distant leadership in impact across all scientific fields. A detailed analysis of the EU15 countries shows some convergence in terms of outputs and impact, but considerable differences among countries remain. These reflect the evolution, not only of their science, technology and higher education systems, but also their integration in the international science system.     

Interest risk and default risk: A conditional volatility study

The aim of this work is to measure the risk-price sensitivity to interest rate changes in the Spanish market and to see if sensitivity is lower with public debt. To contrast this hypothesis, this study presents a model that analyzes the sensitivity of the risky prices before variations in interest rates through duration and convexity, with the purpose of explaining the price of risky bonds. The main advantages of the analysis are the possibility to determine the sensibility of the risky prices before variations of risk-free interest rates in the Spanish market and the construction of a conditional volatility model that overcomes the linearity models of constant variance.     

The inflation bias when the central bank targets the natural rate of unemployment

This paper studies the proposition that an inflation bias can arise in a setup where a central banker with asymmetric preferences targets the natural unemployment rate. Preferences are asymmetric in the sense that positive unemployment deviations from the natural rate are weighted more (or less) severely than negative deviations in the central banker's loss function. The bias is proportional to the conditional variance of unemployment. The time-series predictions of the model are evaluated using data from G7 countries. Econometric estimates support the prediction that the conditional variance of unemployment and the rate of inflation are positively related.     

Does Social Capital Affect Entrepreneurial Intentions?

Nowadays, the scientific community assigns both social context and entrepreneurs’ behavior as a central role in the growth and development of the world economy. However, the relationships between these two factors have not been sufficiently studied in business and economics. Therefore, in this paper, the specific influence of the new socioeconomic factor of social capital on the formation of entrepreneurial intentions will be analyzed. To test the theoretical hypotheses, an empirical study will be carried out using the Partial Least Squares (PLS) technique with data from a sample of young undergraduate students in the last year of their degree. This population has been selected because these individuals, according to different studies, show a higher propensity towards firm creation. A previous version of this paper was presented to the 61st International Atlantic Economic Conference held in Berlin (15–19, March 2006).     

INEQUALITY OF OPPORTUNITY IN BRAZIL

This paper proposes a measure of the contribution of unequal opportunities to earnings inequality. Drawing on the distinction between "circumstance" and "effort" variables in John Roemer's work on equality of opportunity, we associate inequality of opportunities with five observed circumstances which lie beyond the control of the individual—father's and mother's education; father's occupation; race; and region of birth. The paper provides a range of estimates of the importance of these opportunity-forming circumstances in accounting for earnings inequality in one of the world's most unequal countries. We also decompose the effect of opportunities into a direct effect on earnings and an indirect component, which works through the "effort" variables. The decomposition is applied to the distribution of male earnings in urban Brazil, in 1996. The five observed circumstances are found to account for between 10 and 37 percent of the Theil index, depending on cohort and allowing for the possibility of biased coefficient estimates due to unobserved correlates. On average, 60 percent of this impact operates through the direct effect on earnings. Parental education is the most important circumstance affecting earnings, but the occupation of the father and race also play a role.     

A model of endogenous political party platforms

Summary. We develop a model of endogenous party platform formation in a multidimensional policy space. Party platforms depend on the composition of the parties primary electorate. The overall social outcome is taken to be a weighted average of party platforms and individuals vote strategically. Equilibrium is defined to obtain when no group of voters can shift the social outcome in its favor by deviating and the party platforms are consistent with their electorate. We provide sufficient conditions for existence of equilibria.Received: 20 November 2002, Revised: 21 August 2003JEL Classification Numbers: D72, C62.Correspondence to: Ignacio Ortuño-OrtínWe thank A.
