PATTERNS OF INNOVATION IN THE SERVICE SECTOR: SOME INSIGHTS FROM THE SPANISH INNOVATION SURVEY

Although the attention of innovation studies has traditionally been focused on manufacturing, the differential features of innovation activities carried out by services are gaining more and more relevance in innovation research. The aim of this paper is to thoroughly analyse the data from the Spanish Innovation Survey 2000, the first large-scale innovation survey that included service activities in Spain, in order to identify the main patterns of innovation in Spanish services. The results of our investigations confirm that a high degree of heterogeneity, in relation to innovation patterns, exists among service firms and among service industries as well. Nevertheless, important similarities are found between pioneer classifications, such as the theoretical taxonomy of service industries by Soete and Miozzo (1989) Soete, L. and Miozzo, M. 1989. “Trade and Development in Services: A Technological Perspective”. The Netherlands: MERIT Research Memorandum, 89-031. MERIT.  [Google Scholar] or the classification of service firms elaborated by Hollenstein (2003) Hollenstein, H. 2003. Innovation modes in the Swiss service sector: a cluster analysis based on firm-level data. Research Policy, 32(5): 845–863. [Crossref], [Web of Science ®] , [Google Scholar], and the taxonomy we obtained by applying multivariate analysis.     

Service innovation and the proximity-concentration trade-off model of trade and FDI

This paper introduces service innovation in the proximity-concentration trade-off model of trade and foreign direct investments (FDI) [Helpman, E., M. Melitz, and S. R. Yeaple 2004 Helpman, E., M. Melitz, and S. R. Yeaple. 2004. “Export Versus FDI with Heterogeneous Firms.” American Economic Review 94 (1): 300–316. doi: 10.1257/000282804322970814[Crossref], [Web of Science ®] , [Google Scholar]. “Export Versus FDI with Heterogeneous Firms.” American Economic Review 94 (1): 300–316]. The idea is that innovation will have two main effects on service firms’ choice between exports and FDI. First, innovative firms will on average have higher productivity levels than non-innovative enterprises. Secondly, innovators will have to pay a higher relational distance cost for undertaking export activities, and they will, therefore, prefer to avoid (or reduce) these costs by choosing an FDI strategy instead. We test the empirical relevance of this idea on a new survey data set for a representative sample of firms in all business service sectors in Norway. The results show that firms are more likely to choose FDI rather than export the greater their productivity level and the higher the relational distance costs they face.     

Interest rate pass-through and illiquidity shocks in the US

This study examines the US interest rate pass-through mechanism and considers the illiquidity shocks upon retail interest rate correlations caused by financial crises between 1986 and 2011. We estimate a bi-variable EGARCH model using a dynamic conditional correlation model developed by Engle (2002 Engle, R. F. 2002. Dynamic Conditional Correlation: A Simple Class of Multivariate Generalized Autoregressive Conditional Heteroskedasticity Models. Journal of Business and Economic Statistics, 20: 339–350. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) in order to analyze how asymmetric monetary policy influences interest rate pass-through. We test the risks to the dynamic condition and changes in the correlation coefficient. The main empirical results are as follows. First, the long-run interest rate pass-through mechanism is unstable in the US. Second, expected monetary policy impulses are greater than the unexpected ones in the short-run. Finally, according to the one-step and N-step forecast tests, the illiquidity shocks caused by financial crises demonstrate a significant change in retail interest rate risks, but not in correlations between retail interest rates. We conclude that when the interest rate pass-through mechanism is unstable, banks may stop helping each other and will not provide loans to firms and consumers, thereby exhausting the capital of all economic systems. The characteristics of illiquidity enter into the interest rate pass-through mechanism; therefore, the relationship between illiquidity and the interest rate pass-through needs to be investigated.     

A nonparametric revealed preference test of optimal intra-firm resource allocation

The collective rationality hypothesis initiated by Chiappori (1988a Chiappori, PA. 1988a. Rational household labor supply. Econometrica, 56: 63–89. [Crossref], [Web of Science ®] , [Google Scholar]) and applied by Seaton (1997 Seaton, JS. 1997. Neoclassical and collective rationality in household labour supply. Applied Economics Letters, 4: 529–33. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], 2001) for a two-person household is used to distinguish the organizational behaviour of firms. Firms produce satisfaction to groups as traditional managerial and early behavioural theories of the firm of Williamson, Baumol and Marris suggest, as well as more modern principle agent models. Under certain conditions, intra-firm bargaining leads to a Pareto optimal outcome. What makes this work an important contribution is that it identifies a set of nonvacuous testable restrictions to empirically detect if firm-level data satisfy Pareto optimal behaviour for the main decision makers in the organization.     

Spanish stock market sensitivity to real interest and inflation rates: an extension of the Stone two-factor model with factors of the Fama and French three-factor model

This study is focussed on estimating the real interest and inflation sensitivity in Spanish market, proposing an extension of the Stone (1974 Stone, BK. 1974. Systematic interest-rate risk in a two-index model of returns. Journal of Financial and Quantitative Analysis, 9: 709–21. [Crossref], [Web of Science ®] , [Google Scholar]) two-factor model and controlling for size and growth of the companies [Fama and French (1993) three-factor model], because of its importance in the stock sensitivity shown by previous literature. I also study the classical explanatory factors of the stock sensitivity: leverage and liquidity level of the firms. The Spanish stock response is similar to the response in other markets, and the ‘size’ is higher than ‘growth’ effect.     

Does debt market timing increase firm value?

Survey evidence indicates that firm managers try to time debt markets when choosing the maturity of new debt issues, but we do not know whether these strategies increase firm value. This research examines differences in value across nontimers and timers, where timers are defined as firms that follow either a naïve strategy of choosing long-term debt when the term premium is low or a strategy from Baker et al. (2003 Baker, M, Greenwood, R and Wurgler, J. 2003. The maturity of debt issues and predictable variation in bond returns. Journal of Financial Economics, 70: 261–91. [Crossref], [Web of Science ®] , [Google Scholar]) based on the predictability of future excess bond returns. After controlling for various determinants of firm value, the research finds no differences in value across timers and nontimers. It also documents that the timing strategies do not increase firm value and do not affect announcement effects of long-term debt offerings. The results suggest that corporate debt markets are efficient and well integrated with equity markets.     

The extensive and intensive margins of Spanish trade

Recent empirical research highlights that differences in trade flows across countries, products and years are governed by two margins: the intensive margin and the extensive margin. The analysis of the relative contribution of each margin is very important to determine which policies can be more efficient to foster trade at the aggregate, geographic, product or firm level. We use the whole universe of firm level transaction data to analyse the relative contribution of these margins to changes in Spanish trade flows during the 1997–2007 period. We first apply the methodology proposed by Bernard et al. (2009 Bernard, A.B., Jensen, J.B., Redding, S.J. and Schott, P.K. 2009. The margins of US trade. American Economic Review: Papers & Proceedings, 99(2): 487–93. [Crossref], [Web of Science ®] [Google Scholar]) to decompose trade variation over time into three components: net entry of firms, product-country switching and value growth by regular trading firms. The first two components correspond to the extensive margin and the last one refers to the intensive margin. We find that short-run changes in exports and imports are governed by firms’ intensive margin; however, in the long-run, both the extensive and the intensive margins are equally important to foster trade. We also examine the importance of the trade margins at the cross-sectional level for the year 2007. We find that large differences in the Spanish trade flows across countries and products, especially in the case of exports, are explained by the number of firms that participate in trade, which is consistent with the fact that the number of trading partners decline significantly with distance.     

Knowledge technological proximity: evidence from US and European patents

The purpose of this paper is to explore the correlation between the technological proximity measures in three areas: USA, Japan and the Europe. In each economic area, we use information from two international patent systems to construct the technological proximity for 240 large international firms. In particular, we select firms’ patents from United States Patent and Trademarks Office data and European Patent Office data. In order to compute the technological proximity, we follow the methodology developed by Jaffe [1986. “Technological Opportunity and Spillovers of R&D: Evidence from Firms’ Patents, Profits and Market Value.” American Economic Review 76 (5): 984–1001], where a technological vector is based on the distribution of patents of each firm across technology classes. Since the Jaffe distance assumes that spillovers only occur within the same technology class, but rules out spillovers between different classes, we develop also a distance measure which exploits the Mahalanobis norm to identify the distance between different technology classes based on the frequency that patents are taken out in different classes by the same firm. The contribution to the existing literature is to investigate the robustness of the technological proximity measure and the extent to which it may be affected by patent system features.     

Differentials at firm level productive capacity realization in Bangladesh food manufacturing: an empirical analysis

This article empirically estimates the firm-specific productive capacity realization (PCR) indices using the stochastic frontier production function and analyses a number of variables explaining realization rates across firms and over time. Following Battese and Coelli (1995 Battese, GE and Coelli, TJ. 1995. A model for technical inefficiency effects in a stochastic frontier production function for panel data. Empirical Economics, 20: 325–32. [Crossref] , [Google Scholar]) the stochastic frontier production function is used to estimate capacity output and thereby PCR. Using the Firm level panel data from Bangladesh food manufacturing, the results show that capacity realization rates widely vary across firms and over time. The average rate of realization is about 65% implying that most of the firms are producing away from their full production capacity. This article also identifies several firm-specific and policy-related variables explaining capacity realization. The results show that firm size (SZE) and outward orientation (OPN) have positive while capital intensity (CNSTY), market structure (MSTRE) and effective rate of assistance (ERA) have negative impact on realization rates. Strikingly, both policy-related variables are statistically insignificant. Sensitivity analysis using the ‘extreme bound analysis’ also confirms the fragility (insignificance) of these two variables. Excessive support to firms and piecemeal liberalization reform may be attributed to these results. Thus, further reform of the domestic and trade policies are suggested to ensure competition and competitiveness of the manufacturing sector and of the country.     

Immiserizing Growth and the Metzler Paradox in the Ricardian Model

Conditions for the occurrence of immiserizing growth and the Metzler paradox are analysed in the Ricardian model when consumers in the foreign country have Leontief preferences while consumers in the home country have Cobb-Douglas preferences. By using specific functional forms, the conditions for the occurrence of the two paradoxes are defined in terms of the exogenous parameters of the model rather than endogenous variables such as the foreign import demand elasticity in the conditions of Bhagwati (1958) Bhagwati, J. N. 1958. Immiserizing growth: a geometrical note. Review of Economic Studies, 25: 201–205. [Crossref], [Web of Science ®] , [Google Scholar] and Metzler (1949a Metzler, L. A. 1949a. Tariffs, the terms of trade and the distribution of national income. Journal of Political Economy, 57: 1–29. [Crossref], [Web of Science ®] , [Google Scholar], b Metzler, L. A. 1949b. Tariffs, international demand, and domestic prices. Journal of Political Economy, 57: 345–351. [Crossref], [Web of Science ®] , [Google Scholar]). It is shown that the simultaneous occurrence of both paradoxical results is possible for some parameter values.     

Globalization and the effects of changes in functional income distribution on aggregate demand in Germany

Germany has experienced a period of extreme nominal and real wage moderation since the mid‐1990s. Contrary to the expectations of liberal economists, this has failed to improve Germany’s mediocre economic performance. However, Germany is now running substantial current account surpluses. One possible explanation for Germany’s disappointing performance is found in Kaleckian theory, which highlights that the domestic demand effect of a decline in the wage share will typically be contractionary, whereas net exports will increase (Blecker 1989 Blecker, R. 1989. International competition, income distribution and economic growth. Cambridge Journal of Economics, 13: 395–412. [Web of Science ®] [Google Scholar]). The size of the foreign demand effect will critically depend on the degree of openness of the economy. This paper aims at estimating empirically the demand side of a Bhaduri and Marglin (1990 Bhaduri, A. and Marglin, S. 1990. Unemployment and the real wage: The economic basis for contesting political ideologies. Cambridge Journal of Economics, 14: 375–93. [Crossref], [Web of Science ®] [Google Scholar]) type model for Germany. The paper builds on the estimation strategy of Stockhammer, Onaran, and Ederer (2009 Stockhammer, E., Onaran, Ö. and Ederer, S. 2009. Functional income distribution and aggregate demand in the Euro area. Cambridge Journal of Economics, 33(1): 139–59. [Crossref], [Web of Science ®] [Google Scholar]) and Hein and Vogel (2008 Hein, E. and Vogel, L. 2008. Distribution and growth reconsidered – empirical results for six OECD countries. Cambridge Journal of Economics, 32: 479–511. [Crossref], [Web of Science ®] [Google Scholar], 2009 Hein, E. and Vogel, L. 2009. Distribution and growth in France and Germany – single equation estimations and model simulations based on the Bhaduri/Marglin‐model. Review of Political Economy, 21(2): 245–72. [Taylor & Francis Online] [Google Scholar]). The main contribution lies in a careful analysis of the effects of globalization. Since Germany is a large open economy by now it is a particularly interesting case study.     

Estimation of SEs for heteroscedastic and cross-sectionally correlated data

This study develops SE estimators for heteroscedastic and cross-sectionally correlated data. The new estimators are a cross-sectional version of the White and Domowitz (1984 White, H and Domowitz, I. 1984. Nonlinear regression with dependent observations. Econometrica, 52: 143–61. [Crossref], [Web of Science ®] , [Google Scholar]) and Newey and West (1987 Newey, W and West, K. 1987. A simple positive semi-definite, heteroscedasticity and autocorrelation consistent covariance matrix. Econometrica, 55: 703–8. [Crossref], [Web of Science ®] , [Google Scholar]) estimators, and therefore, consistent in the presence of heteroscedasticity and cross correlation of unknown form. Unlike the estimators in the literature, these estimators can control for cross correlation even for single-period cross-sectional data.     

Structural changes and regional disparity in China's inflation: a revisit

The study re-examined the time series properties and regional disparities in Chinese inflation by extending the work of Chong, Zhang, and Feng (2011 Chong, Tai-Leeung, Terence, Ning Zhang and Feng, Qu. 2011. Structural Changes and Regional Disparity in China's Inflation. Economics Bulletien, 31(1): 572–583.  [Google Scholar]). For this purpose we employed the Lagrange Multiplier (LM) unit root test with one structural break and two structural breaks suggested by Lee and Strazicich (2003 Lee, Junsoo, Mark, C. and Strazicich. 2003. Minimum LM Unit Root Test with Two Structural Breaks. Review of Economics and Statistics, 85(4): 1082–1089. [Crossref], [Web of Science ®] , [Google Scholar], 2004 Lee, J. and Strazicich, M. 2004. Minimum LM unit root test with one structural break. Working Paper 04–17, Boone, North Carolina: Department of Economics, Appalachian State University.  [Google Scholar]) and a recently developed ADF type unit root test with two structural breaks of Narayan and Popp (2010 Narayan, Paresh Kumar and Stephan Popp. 2010. A New Unit root test with Two Structural Breaks in Level and Slope at Unknown Time. Journal of Applied Statistics, 37(9): 1425–1438. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). We found that national, urban and rural series of the overall inflation series, clothing, and food, national series of education and residence and the rural series of residence and education are stationary. We also found regional disparity in Chinese inflation, but the disparities existed only in education inflation series.     

Unit roots and purchasing power parity: another kick at the can

Lopez et al. (2005 Lopez, C, Murray, C and Papell, D. 2005. State of the art unit root tests and purchasing power parity. Journal of Money, Credit and Banking, 37: 361–9. [Crossref], [Web of Science ®] , [Google Scholar]) demonstrated that single-equation unit-root tests cannot provide conclusive evidence of whether real exchange rates are stationary because inference depends critically on the lag-lengths used to construct the test statistics, a result reinforced by a recent work by Sweeney (2006 Sweeney, D. 2006. Mean reversion in nominal G-10 exchange rates. Journal of Financial and Quantitative Analysis, 41: 685–708. [Crossref], [Web of Science ®] , [Google Scholar]). The purpose of this article is to revisit the issue, first demonstrating the necessary conditions under which this approach of testing for Purchasing Power Parity (PPP) is appropriate.     

What (if any) are the returns to computer use?

Using North American data, we revisit the question first broached by Krueger (1993 Krueger, AB. 1993. How computers have changed the wage structure: evidence from microdata. Quarterly Journal of Economics, 108: 33–60. [Crossref], [Web of Science ®] , [Google Scholar]) and re-examined by DiNardo and Pischke (1997 DiNardo, JE and Pischke, J-S. 1997. The returns to computer use revisited: have pencils changed the wage structure too?. Quarterly Journal of Economics, 112: 291–303. [Crossref], [Web of Science ®] , [Google Scholar]) of whether there exists a real wage differential associated with computer use. Employing a mixed effects model with matched employer–employee data to correct for the fact that workers and workplaces that use computers are self-selected, we find that computer users enjoy an almost 4% wage premium over nonusers. Failure to correct for worker and workplace selection effect leads to a more than twofold overestimate of this premium.     

Modelling the dynamics of EU economic sentiment indicators: an interaction-based approach

This article estimates a simple univariate model of expectation or opinion formation in continuous time adapting a ‘canonical’ stochastic model of collective opinion dynamics (Weidlich and Haag, 1983 Weidlich, W, and Haag, G, 1983. Concepts and Models of a Quantitative Sociology. Berlin: Springer; 1983.[Crossref] , [Google Scholar]; Lux, 1995 Lux, T, 1995. Herd behavior, bubbles and crashes, The Economic Journal 105 (1995), pp. 881–96.[Crossref], [Web of Science ®] , [Google Scholar], 2009a Lux, T, 2009a. Rational forecasts or social opinion dynamics? Identification of interaction effects in a business climate survey, Journal of Economic Behavior and Organization 72 (2009a), pp. 638–55.[Crossref], [Web of Science ®] , [Google Scholar]). This framework is applied to a selected data set on survey-based expectations from the rich EU business and consumer survey database for 12 European countries. The model parameters are estimated through Maximum Likelihood (ML) and numerical solution of the transient probability density functions for the resulting stochastic process. The model's success is assessed with respect to its out-of-sample forecasting performance relative to univariate Time Series (TS) models of the Autoregressive Moving Average model, ARMA(p,?q) and Autoregressive Fractionally Integrated Moving Average, ARFIMA(p,?d,?q) varieties. These tests speak for a slight superiority of the canonical opinion dynamics model over the alternatives in the majority of cases.     

Financial development and economic growth nexus: a time-series evidence from India

This study examines the relationship between financial development and economic growth in India for the period 1951–52 to 1995–96. The long-run equilibrium and short-run dynamic models are estimated using financial interrelations ratio and new issue ratio as the measures of financial development, a la Goldsmith (1969 Goldsmith, RW. 1969. Financial Structure and Development, New Haven: Yale University Press.  [Google Scholar]). The Johansen (1991 Johansen, S. 1991. Estimation and hypothesis testing of cointegration vectors in Gaussian vector autoregressive models’. Econometrica, 59: 1551–80. [Crossref], [Web of Science ®] , [Google Scholar]) estimator rejects the null of zero cointegrating vector and shows the presence of long-run equilibrium relationship between financial development and economic growth. The error correction model, impulse response and variance decomposition analyses (Sims, 1980 Sims, CA. 1980. Macroeconomics and reality. Econometrica, 48: 1–48. [Crossref], [Web of Science ®] , [Google Scholar]), and the Toda and Yamamoto (1995 Toda, HY and Yamamoto, T. 1995. Statistical inference in vector autoregressions with possibly integrated processes. Journal of Econometrics, 66: 225–50. [Crossref], [Web of Science ®] , [Google Scholar]) estimator show the presence of bidirectional Granger-causality between financial development and economic growth. The presence of bidirectional Granger-causality suggested by these estimators points towards the possible problem of endogeneity and simultaneity bias in the growth models that examine the contemporaneous effect of financial development on economic growth. The economic reforms that started since July 1991 emphasized on the liberalization and development of financial sector to supplement the efforts aimed at achieving high economic growth in India.     

Nonlinearity in real exchange rates: an approach with disaggregated data and a new linearity test

Employing disaggregated real exchange rates from nine European counties in 16 goods categories, we assess in this study the nonlinearity in the real exchange rates. Surprisingly, we find evidence for nonlinearity in only four (10) out of 143 series with the linearity test proposed by Harvey et al. (2008 Harvey, D. I., Leybourne, S. J. and Xiao, B. 2008. A powerful test for linearity when the order of integration is unknown. Studies in Nonlinear Dynamics and Econometrics, 12 Art 8[Web of Science ®] , [Google Scholar]) at the 5% (10%) significance level. This result differs greatly from those of Juvenal and Taylor (2008 Juvenal, L. and Taylor, M. P. 2008. Threshold adjustment of deviations from the law of one price. Studies in Nonlinear Dynamics and Econometrics, 12 Art 8[Web of Science ®] , [Google Scholar]), Imbs et al. (2003 Imbs, J., Mumtaz, H., Raven, M. O. and Rey, H. 2003. Nonlinearities and real exchange rate dynamics. Journal of the European Economic Association, 1: 639–49. [Crossref] , [Google Scholar]), Sarno et al. (2004 Sarno, L., Taylor, M. P. and Chowdhury, I. 2004. Nonlinear dynamics in deviations from the law of one price: a broad-based empirical study. Journal of International Money and Finance, 23: 1–25. [Crossref], [Web of Science ®] , [Google Scholar]) and Berka (2009 Berka, M. 2009. “Non-linear adjustment in law of one price deviations and physical characteristic of good”. In Review of International Economics Vol. 17, 51–73.  [Google Scholar]), who report ample evidence for nonlinearity for the same or similarly disaggregated real exchange rate datasets.     

Samuelson and Davidson on ergodicity: A reformulation

The concept of ergodicity in economics seems to have the qualities of a shibboleth—a word or saying used by adherents of a party, sect, or belief, and usually regarded by others as empty of real meaning. It is in use by both neoclassical economics—after Samuelson (1965 Samuelson, P. A. “Proof That Properly Anticipated Prices Fluctuate Randomly.” Industrial Management Review, 1965, 6 (2), 41–49.[Web of Science ®] , [Google Scholar], p. 43), who used the term in his paper on what later became a foundation of the efficient market hypothesis—and post Keynesian economics—after Davidson, who picked up the term in order to highlight methodological differences. Considering the origin of the concept in statistical physics and its use in the topology of dynamical systems, which most economists are not conversant with, the importance ascribed to ergodicity in economic debate seems mystifying. We deconstruct the meaning of the term in the major contributions of Samuelson and Davidson. We suggest an alternative to (non)ergodicity to discuss the nature of randomness in the real world. While neoclassical theory assumes stochastic randomness, post Keynesians assume nonstochastic randomness, a term developed by the mathematician Kolmogorov (1986 Kolmogorov, A.N. “On the Logical Foundations of Probability Theory.” In K. Ito, and J.V. Prokhorov (eds.), Probability and Mathematical Statistics, Moscow, 1986, pp. 467–471. [Google Scholar], p. 467). We argue that even in an ergodic world there is a problem with the idea that stochastic randomness can be dealt with by the financial system.     

Convergence in household credit demand across euro area countries: evidence from panel data

This article contributes to the literature on the convergence of financial systems in the euro area by estimating household credit demand in individual countries. Using the ARDL framework advocated notably by Pesaran et al. (1999 Pesaran, MH, Shin, Y and Smith, RP. 1999. Pooled mean group estimation of dynamic heterogeneous panels. Journal of the American Statistical Association, 94: 621–34. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), the article provides evidence on the convergence of long-run credit demand determinants (interest rates, investment and house prices) in the largest euro area countries, while short run-dynamics remain heterogenous across countries. The article also demonstrates that the equation uncovers demand rather than supply behaviour.
