Consumption and disposable income in the EU countries: the role of wealth effects

We investigate the long run relationship between private consumption and disposable income for a sample of EU countries using recently developed panel cointegration techniques. For the ordinary consumption-income model the evidence on cointegration is ambiguous. In addition, the cointegration vector obtained by efficient estimation methods is not consistent with theoretical reasoning, as it reflects a decline in the savings rate over time. Extending the analysis by financial wealth improves the model fit markedly. In particular, the income elasticity is not different from 1 and therefore in line with the life cycle permanent income hypothesis. The marginal propensity to consume out of financial wealth is in a range of 3–5%, thereby confirming recent time series results.     

Measuring uncertainty of the euro area NAIRU: Monte Carlo and empirical evidence for alternative confidence intervals in a state space framework

This paper investigates uncertainty around point estimates of the euro area NAIRU in a state space framework. The relative accuracy of alternative measures of uncertainty for state space models are compared using Monte Carlo simulations. A direct bootstrap method yields confidence intervals with lower coverage probability than confidence intervals based on mean squared errors (MSE) approximations. The degree of uncertainty of the euro area NAIRU is estimated with a trivariate state space model. The direct bootstrap method shows the narrowest confidence interval compared with the MSE approximations. However, the wider intervals based on MSE approximations are narrow enough for the identification of some periods in time where observed unemployment and the NAIRU differ significantly.     

On the impact of innovation and inequality in economic growth

We present robust results on the empirical relationship among income inequality, innovation, and economic growth for a panel dataset of 74 countries over the period 1996–2014. We estimate pairwise causality tests to show that there is bidirectional causality between GDP per capita and R&D, while R&D causes the Gini index of income inequality, and it causes human capital. Allowing coefficients to be different across cross-sections of countries, we get in any case a pairwise bi-directionality. By dynamic panel data estimations, when regressing R&D on GDP per capita, we obtain a threshold value of 0.16% of R&D such that for values above it there is economic growth. While regressing R&D on the Gini index, we get a threshold of 0.10% of R&D above which, the income distribution begins to improve. Finally, we estimate a growth equation that depends on R&D, income inequality, and physical capital. We obtain two thresholds, one of 38.79 for the Gini (above which the economic growth decreases), and one of 0.06% for R&D such that above it, economic growth is rising.

Beyond absorptive capacity in open innovation process: the relationships between openness,capacities and firm performance

The literature has shown that open innovation (OI) can be a winning strategy in improving firm performance. However, in order to adopt and implement it, managers need to resolve practical problems, such as understanding the role played by OI capacities and openness on firm performance. In response to these needs, this study aims to investigate the hierarchical relationships between openness, OI capacities and performance using a structural equation model approach. This paper also attempts to compare the levels of openness between firms in different industries to discover similarities and differences in OI phenomena. The analysis of data obtained from a survey of Korean firms shows significant interrelations between openness, OI capacities and firm performance. Our results go further in developing understanding of the building blocks on which successful OI is built and particularly suggest that desorptive capacity which underpins the out-bound OI process, is in turn strongly supported by knowledge management capacity. It is hoped that the results of this study can enrich our understanding of the OI mechanism and provide managerial and policy implications.     

The process and experiences with creating user-driven innovation programmes in the Netherlands

In 2005 the Netherlands drafted a new innovation policy, consisting of a basic package for all entrepreneurs and a programme-based package aimed at supporting the Dutch industry in achieving global excellence in a limited number of (business) areas. The programme-based package is characterized by an integral approach, resulting in user-driven public-private innovation programmes. In the new approach, industrial foresight processes are integrated with actual policy implementation. In this paper, we include the lessons learned during the process that led to the first innovation programmes. Also, some unresolved issues in the new approach are discussed.

Steady states in the OLG model with seignorage and long-lived agents

This note provides a direct proof of the fact that in a particular version of the overlapping generations model with long-lived agents and fiat money, there can be at most two stationary states. A simple argument showing the Pareto superiority of the low inflation steady state is also given.     

The development of research and innovation policies based on a benchmarking assessment: the case of mobile communications technology R&D in the new member states of the EU

This paper presents the process and the results that led to an objective assessment of 34 research programmes from 14 countries based on a multifactor analysis. The programmes that were analysed come from the EU's new member states and the accession countries. The methodology used was specially developed for policy development purposes and for the design of the roadmaps leading to an open and successful R&D programme in the area of mobile communications. The method and the results obtained and later used for the policy development and road mapping are discussed. The policies designed and strategic objectives derived are briefly described. The consequences expected to follow the policy implementation in the relevant countries are evaluated and discussed.
