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.     

Co-evolution of firms and strategic alliances: Theory and empirical evidence

This paper reviews the analogies of evolution and co-evolution within a business context. Specifically it examines some of the essential underlying assumptions of these theories including the unit of change, the unit of selection; the mechanism of selection, and the ability to change an organisational form. The usefulness of the application of theories of both evolution and co-evolution to explain firm behaviour is examined. Empirical evidence from the UK fresh produce industry is presented to illustrate that both firms and strategic alliances evolve, co-evolve and are subject to selection at individual, dyadic and group levels simultaneously.     

Sovereign risk and deposit dynamics: evidence from Europe

The unprecedented expansion of sovereign balance sheets since the beginning of the global crisis has given a new meaning to the term sovereign risk. Developments in Europe since early 2010 revealed new challenges for the functioning of private banks in an environment of heightened sovereign risk and may have contributed to deleveraging. The article uses an innovative way of measuring the perception of sovereign risk and its impact. Using an extension of a common market discipline framework, it shows that exposure to sovereign risk may have limited the ability of banks in Europe to collect deposits. Potential identification issues between deposits and bank efficiency are controlled by using data envelopment analysis (DEA). The results are robust to inclusion of conventional measures of bank performance and the sector-wide holdings of foreign sovereign debt.     

Vertical integration,escalating commitment and technological performance: evidence from firms in the US computer industry

We set out in this study to analyse the impact on the technological performance of firms arising from their vertical integration, along with their escalating commitment to capital investment. Our findings reveal a positive relationship between vertical integration and the technological performance of such firms. A positive correlation is also found to exist between vertical integration and escalating commitment to capital investment; in other words, a firm's rising commitment to its capital investment may well strengthen the positive effects of vertical integration on the technological performance of the firm. More importantly, the interactive effects on technological performance will tend to differ, largely dependent on the type of vertical integration. The findings of this study also indicate that vertical integration can effectively neutralise the threat to exit barriers resulting from a firm's escalating commitment to its prior investment.     

Institutional arrangements and price rebalancing: empirical evidence from the United States and Europe

This paper explores the rebalancing of prices for voice service in the United States (US) and the European Union (EU) from conceptual and empirical perspectives. We determine the overall cost and structure of a standardized basket of residential and business services. Our data indicate that during the 1994–2000 period the degree of rate rebalancing was significantly higher in the EU than in the US. While the developments at the level of EU Member States are more heterogeneous and the process of rate rebalancing is not completed, these findings correspond to the predictions derived from our comparative institutional analysis.     

Internalization of externalities and local government consolidation: empirical evidence from Japan

The fact that jurisdictional consolidation overcomes externality problems in the provision of local public goods is one of the best-known benefits of consolidation in the theoretical literature. Nevertheless, previous studies provide little evidence of how public service spillover effects influence consolidation decisions. This study empirically tests the hypothesis that spillovers induce consolidation, using voting data on the consolidation of Japanese municipalities. The extent of spillovers is measured by estimating the demand function for public goods with externalities. It is found that residents of the municipalities that can internalize a large amount of public goods spillovers through municipal consolidation tend to favor consolidation. This result supports the theoretical inference that spillovers in local public goods affect utility gains from jurisdiction integration, thus serving as one of the key impetuses for boundary reform. Moreover, after controlling for the spillover effects, economies of scale, population share, differences in median income, and unconditional grants can help explain consolidation preference.     

Knowledge,location, and internationalization: empirical evidence for manufacturing SMEs

This paper investigates the links between locational conditions, innovative capabilities, and internationalization of manufacturing small and medium-sized enterprises (SMEs). Two modes of foreign market servicing are explored: exporting activity and relocating of selected business activities abroad. The analysis is based on the survey of about 3000 firms. The results reveal that the outputs of SMEs' innovative activities – product innovations and patent applications – enhance exporting propensity. Nevertheless, the input-side indicator – R&D intensity – appears to exert no impact. Furthermore, the locational factor proximity to research institutions promotes SMEs' exporting. Regarding the determinants of selective relocations abroad, the findings show that SMEs with a high degree of R&D are less likely to separate production from other operations and relocate it abroad. Moreover, manufacturing SMEs assessing the proximity to research facilities, as well as support from various regional authorities as important and good-quality locational conditions, exhibit a significantly lower likelihood to relocate selected activities abroad.     

Industrial structure in US telecommunications: some empirical evidence

The telecommunications industry in the US is re-assessed using a methodology which incorporates new developments in time-series analysis. The issue of natural monopoly is re-considered with a view to the validation of the use of applied econometry in the fields of divestiture and industrial policy. Recent developments in US telecommunications are considered and incorporated into the model.     

Linear and non-linear transmission of equity return volatility: evidence from the US, Japan and Australia

This paper models the transmission of shocks between the US, Japanese and Australian equity markets. Tests for the existence of linear and non-linear transmission of volatility across the markets are performed using parametric and non-parametric techniques. In particular the size and sign of return innovations are important factors in determining the degree of spillovers in volatility. It is found that a multivariate asymmetric GARCH formulation can explain almost all of the non-linear causality between markets. These results have important implications for the construction of models and forecasts of international equity returns.     

Knowledge codification and technological innovation success: Empirical evidence from Spanish biotech companies

This paper analyzes the influence of knowledge codification on technological innovation in a sample of Spanish firms from the biotechnology sector. It tests how codification affects firms' development of incremental and radical innovations and their attempts to keep their investments exclusive by building barriers to imitation and to substitution. The work also considers the incorporation of legal protection measures. The results show, on the one hand, that knowledge codification is only beneficial for developing incremental innovations and, on the other, that firms must incorporate systems of legal protection into their codification practices if they want to keep their innovations exclusive.     

Gender diversity,cash holdings and the role of the institutional environment: empirical evidence in Europe

While substantial evidence is emerging internationally on higher risk aversion among women than among men, there is less evidence on women’s business choices. We explore some of the reasons for the relationship between gender diversity and cash holdings. Specifically, this paper focuses on the choices involving the stock of cash held by firms in which women have executive roles and can consequently exert a crucial influence on the firms themselves. We estimate our proposed empirical models using a dataset of 12,466 observations from 18 European countries. We find a positive relationship between the presence of women with executive roles in the firm and cash holdings. Women tend to make more conservative choices probably because they are more risk averse than men are. This propensity has a relevant impact on the financial choices of firms when women play a leading role. Notably, the study demonstrates that the institutional environment and industry differences moderate our baseline relationship.

Cross-sectional and time-series momentum returns and market dynamics: evidence from Japan

We test the behavioural theories of overconfidence and underreaction on cross-sectional (CS) and time-series (TS) momentum returns in the Japanese stock markets. Both CS and TS momentum returns are large and significant when the market continues in the same state and turns into losses when the market transitions to another state, consistent with the overconfidence but not the underreaction model. We find that TS conditional momentum returns exceed conditional CS momentum returns because of its active position since TS takes a net long (short) position following UP (DN) markets while CS is a zero-cost strategy irrespective of the market state. Finally, we find no relation between idiosyncratic volatility (IV) and momentum returns which is not supportive of either the overconfidence or underreaction model but implies that IV is not a significant limit to arbitrage in Japan.     

Interrelationship among institutional infrastructure,technological innovation and growth. An empirical evidence

This paper uses a multi-equation model to achieve an overall study of two key factors which explain growth, technology and institutions. The paper focuses on the process of the accumulation of these factors and the interrelationship arising among them. A theoretical model is given, together with empirical evidence for the joint impact of these factors on economic growth in a wide-ranging sample of countries between 1985 and 1997. This paper also contributes certain novel aspects in the variables employed. Thus, an indicator of human capital and an index reflecting institutional infrastructure have been used. The human capital indicator considers health, formal education, informal education and accumulated experience. It embraces a wider range of factors than the variables conventionally used in empirical studies. As to the institutional infrastructure index, it has been constructed on the basis of six institutional sub-indices, comprising voice and accountability, political stability, government effectiveness, regulatory quality, rule of law and control of corruption. Thus, the index constructed captures a greater wealth of the items commonly covered by the concept of institutions.     

The empirical content of the job search model: Labor mobility and wage distributions in Europe and the US

Job search models of the labor market hypothesize a very tight correspondence between the determinants of labor turnover and individual wage dynamics on one hand, and the determinants of wage dispersion on the other. This paper offers a systematic examination of whether this correspondence is present in the data by estimating a rudimentary partial equilibrium job search model on a 3-year panel of individual worker data covering 10 European countries and the U.S. We find that our basic job search model fits the data surprisingly well. This also allows us to point at a number of interesting empirical regularities about wage distributions. Our results suggest that cross-sectional data on individual wages contain the basic information needed to obtain a reliable measure of the “magnitude of labor market frictions”, as measured by a parameter of the canonical job search model. Finally, we use our results in a cross-country comparison of the intensity and nature of job-to-job turnover. We arrange countries into two different groups according to their turnover intensity. We further show that the nature of job-to-job turnover is very different between those two groups: Turnover is predominantly voluntary in low-turnover countries, whereas it is to a large extent involuntary in high-turnover countries.     

Health,time allocation and work: empirical evidence from Turkey

This article investigates the relationship between health status and time allocation decisions of individuals. Although many studies address impacts of health on labour supply, few studies explore associations of health status with non-market work activities. Using a nationally representative sample from a recent Turkish Time Use Survey, this article employs Seemingly Unrelated Regression (SUR) framework to estimate multiple equations of various time use categories. Consistent with literature, empirical results indicate that higher levels of self-reported health status (SRHS) are associated with more time spent in market work. However, better health level is negatively correlated with time spent in leisure and sleep. There is mixed evidence between self-reported health status (SRHS) and time spent on non-market work. There is a negative weak association between health and time devoted to personal care. Finally, demographics such as gender, age, education and marital status display correlations with time allocation of Turkish individuals.     

Parental risk attitudes and children's academic test scores: evidence from the US panel study of income dynamics

Using a sequence of questions from the 1996 US Panel Study of Income Dynamics (PSID), we explore the implications of interpersonal differences in parent's attitudes towards risk for the academic test scores of their children focusing on information drawn from the 1997 Child Development Supplement of the PSID. In addition, we explore whether parental risk preference influences whether the child subsequently attends college. Our findings suggest that a parent's degree of risk aversion is inversely related to the academic test scores of their children as well as being inversely related to the probability of attending college post high school.     

Government size,decentralization and growth: empirical evidence from Italian regions

The aim of this study is to empirically assess the relationship among government size, decentralization and economic growth in Italian ordinary regions. The empirical analysis, based on a panel dataset on Italian regions, provides evidence in support of the existence of an inverted U-shaped relationship between public expenditure and economic growth, that depends on the degree of fiscal decentralization. In particular, according to our estimates on the specific Italian case, the optimal degree of decentralization is around 32%, while the optimal government size value is approximately 52%.
