Patents,technological inputs and spillovers among regions

This article analyses the importance of different technological inputs (R&D and human capital) and different spillovers in explaining the differences in patenting among Spanish regions in the period 1986 to 2003. The analysis is based on the estimation of a knowledge production function. A region's own R&D activities and human capital are observed to have a positive significant effect on innovation output, measured by the number of patents. R&D spillovers weighted by the distance and the volume of trade flows between regions cause positive effects on a region's patents. However, distance matters more than the intensity of trade flows and the R&D spillover effects between regions are bounded: spillovers from closer regions perform better than spillovers from distant regions. On the opposite side, human capital spillovers do not cause any effect outside the region itself.     

The impact of the United States subsidies on world cotton price: evidence from ARDL bounds tests

This article investigates the impact of the United States subsidies on world cotton price in a structural framework. It starts with a simultaneous equations model of world cotton market, and then, it focuses on the reduced form. Using the Autoregressive Distributed Lag (ARDL) bounds tests of Pesaran et al. (2001), no evidence of cointegration is found between the underlying variables. This contrasts with results found in the classical framework, which highlight a strong evidence of a negative impact of subsidies on cotton price, either in the short or long run.     

Inequality of Opportunity in Brazil: A Corrigendum

This note acknowledges and corrects a programming error in our paper “Inequality of Opportunity in Brazil” (Review of Income and Wealth, 53(4), 585–618, 2007). Once the error is corrected, our bounds approach to the identification of individual model parameters in the presence of omitted variable biases is much less useful than indicated in the original paper. In the specific context of the measurement of inequality of opportunity, this implies that the decomposition of overall inequality of opportunity into direct and indirect effects is not reliable. However, the parametric approach introduced in our paper remains useful for obtaining a lower‐bound estimate of overall ex‐ante inequality of opportunity, as proposed by Ferreira and Gignoux (2011).     

Debt ownership structure and legal system: an international analysis

This paper is concerned with the ownership structure of corporate debt from an institutional perspective. An attempt is made to identify the factors affecting bank debt use from an international sample of companies from Austria, Germany, Japan, Belgium, France, Italy, Holland, Spain, Portugal, Finland, Sweden and the USA. The results show that bank debt depends both on factors specific to each company and on institutional features of each country. More exactly, it is found that bank loans are related to firm size, to the quality and risk of the projects, and to the collateral. It is also found that a number of legal-institutional factors are impacting on the source of firms’ debt, such as creditor protection, firm disclosure requirements and law enforcement.     

Persistent misalignments of the European exchange rates: some evidence from non-linear cointegration

The asymmetric and persistent adjustment of the European real exchange rates is investigated using the framework of non-linear cointegration. The episodes of slow mean-reversion dynamics over the period from 1979 to 1999 are explained. A test of unit root against STAR cointegration is proposed and some complete estimations and stochastic simulations of ESTAR models are presented. The presence of effective non-linear adjustment during the moving of the currencies to their long-run fundamental equilibrium exchange rate value is discussed.     

The effects of macroeconomic stability on foreign trade. An analysis for Spain, 1986–2000

Two main factors underlie the rebirth of interest in the study of the influence of the real exchange rate on trade, the reduction of its volatility and the current trend towards price stability. The objective of this study is to analyse the effects of the process of nominal convergence, required of the European member states for the fulfilment of monetary integration, on foreign trade flows. The case of Spain, which is especially interesting in this context, is studied for the period 1986 to 2000. The results of estimating the aggregate functions of the export and import of goods shows how macroeconomic stability has altered the behaviour of trade with respect to the two basic determinants – income and prices – how it has caused a significant structural change in the real exchange rate and, finally, how it has laid the explanatory bases for transactions in the twenty-first century with the single currency – the euro.     

The determinants of efficiency: the case of the Spanish industry

The aim of this paper is to analyse the factors explaining the technical efficiency of Spanish industrial sectors during the period 1991–1994 using the Survey of Business Strategies (SBE) of the Ministry of Industry and Energy. It analyses whether efficiency can be explained by factors external to the firm such as the degree of competition in the markets in which it operates, characteristics of the firm (size, organization, advantages of location, participation of public capital, etc.), as well as the effects of dynamic disturbances that may affect the degree of utilization of the productive capacity.     

How do financial frictions affect the spending multiplier during a liquidity trap?

We show that credit market imperfections substantially increase the government-spending multiplier when the economy enters a liquidity trap. This finding is explained by the tight association between capital goods and firms? collateral, a relationship that we highlight as the capital-accumulation channel. During a liquidity trap, a government spending expansion reduces the real interest rate, leading to a period of cheap credit. Entrepreneurs use this time to accumulate capital, which persistently improves their balance sheets and reduces their future costs of credit. A public spending expansion can thus encourage private investment, yielding consequently a large spending multiplier. This effect is further reinforced by Fisher?s debt-deflation channel.     

Sen and Commons on Markets and Freedom

Amartya Sen's enlarged conception of freedom has augmented the scope of economic analysis but it also has had the surprising effect of being more supportive of the free market than conventional welfare economics. It is argued here that a comparison of Sen's position with that of the American institutionalist, J R Commons, highlights some problems with Sen's approach and points to possible ways in which they might be addressed.
