Rent Protection as a Barrier to Innovation and Growth

We build a model of R&D-based growth in which the discovery of higher-quality products is governed by sequential stochastic innovation contests. We term the costly attempts of incumbent firms to safeguard the monopoly rents from their past innovations rent-protecting activities. Our analysis (1) offers a novel explanation of the observation that the difficulty of conducting R&D has been increasing over time, (2) establishes the emergence of endogenous scale-invariant long-run innovation and growth, and (3) identifies a new structural barrier to innovation and growth. We also show that long-run growth depends positively on proportional R&D subsidies, the population growth rate, and the size of innovations, but negatively on the market interest rate and the effectiveness of rent-protecting activities. An unpublished version of this paper was circulated earlier under the title “Innovation and Rent Protection in the Theory of Schumpeterian Growth.” We thank an anonymous referee and seminar participants in several venues for useful comments and suggestions.     

Hormone beef, chlorinated chicken and international trade

We study international trade in innovative goods subject to uncertain consumer health effects. Such goods are often at the center of international trade disputes. We show that an interesting form of protectionism may arise because of scientific uncertainty. A free-riding effect is identified, implying more conservative behavior by countries. We also study the role of producers (lobbies) in providing valuable information, finding that the innovative lobby has an advantage in providing information as compared with the lobby producing the ‘traditional’ good. Moreover, lobbies disclose more information when the health effects are long lasting.     

Analysing the stakes of stakeholders in research and development project management: a systems approach

Research and development (R&D) project management involves managing multiple stakeholders with conflicting stakes. This article proposes a systems approach to capture such conflicting stakes of multiple stakeholders in controversial R&D projects. The approach is illustrated using a New Zealand case study related to the use of 1080 chemical for pest management. Initially, the problem situation was structured systemically by analysing the behaviour of the main variables and by conducting a stakeholder analysis. Further, a participative systems model related to the problem situation was developed using a group model‐building process. The analysis of the model revealed a set of feedback loops operating in the system identified as constituting and responsible for the complexity of the problem situation relating to 1080 use. In conclusion, the paper highlights some strategies suggested by the stakeholders to manage conflict.     

Voluntary Provision of Public Goods and Technology

This paper highlights issues in the theory of voluntary provision of public goods, building on the investigation by Peacock in connection with the contributions by Coase and Buchanan. Our goal is twofold. We first draw attention to the early literature investigating the provision of public goods and to the successive theoretical analysis. We then focus on the impact of technology on supply and demand. Examples of different types of public goods are provided, with special attention to the cultural sector, to investigate whether and how technology affects the efficiency and the effectiveness of the related public goods provision. The implementation and exploitation of technological advancements are investigated in view of the role of different actors (public, private) at different levels of government.     

Island cruise tourism development: a resident's perspective in the context of Italy

Most studies that examine tourism impacts and community attitudes have been carried out from the perspective of the tourism sector as a whole, with very few papers focusing on specific types of tourism and/or analysing tourists' preferences for specific types of tourism segment. This paper discusses some pertinent issues in relation to cruise tourism development and community attitudes in a port of call cruise destination located in the island of Sicily (Southern Italy). Specifically, this study was carried out using a quota random sample of 1500 responses, which is representative of the population of Messina at 1% level. Findings show that residents express an overall positive attitude towards cruise tourism development even if it is not the most preferred when compared to other types of tourism (cultural tourism, sport tourism, and sun and sea tourism). Further, they highlight that significant differences based on socio-economic and demographic characteristics (age, gender, reliance on cruise-related employment, level of education, geographical proximity to tourist areas and port, length of residency and frequency of interaction with tourists) exist in residents' perceptions and attitudes towards cruise tourism development. Implications for policy-makers are discussed and suggestions for further research are given.     

FROM BOTTOM TO TOP: THE ENTIRE INCOME DISTRIBUTION IN GERMANY, 1992–2003

We analyze the distribution of market income in Germany in the period 1992 to 2003 on the basis of an integrated dataset that encompasses the whole spectrum of the population, from the very poor to the very rich. We find a modest increase of the Gini coefficient, a substantial drop of median income and a remarkable growth of the income share accruing to the economic elite, which we define as the richest 0.001 percent of persons in the population. While the elite mainly obtains its income from business and capital, the income share that it receives in the form of wage income has been increasing. We also show that the dramatic decline of market income in the bottom half of the distribution is very much mitigated by income transfers within private households and by governmental redistribution.     

Symbolic values, occupational choice, and economic development

Channeling human resources into occupations with high social productivity has historically been a key to economic prosperity. Occupational choices are not only driven by the material rewards associated with the various occupations, but also driven by the esteem that they confer. We propose a model of endogenous growth in which occupations carry a symbolic value that makes them more or less attractive; the evolution of symbolic values is endogenously determined by purposive transmission of value systems within families. The model sheds light on the interaction between cultural and economic development and identifies circumstances under which value systems matter for long-run growth. It shows the possibility of culturally determined poverty traps and offers a framework for thinking about the transition from traditional to modern values.     

Measuring core inflation in Italy comparing aggregate vs. disaggregate price data

This paper focuses on the core inflation measurement in Italy using univariate (national-level inflation) vs. multivariate (city-level inflation) models during the period 1970–2006. We derive algebraic expressions that allow comparison between the reduced form parameters of univariate and multivariate local level models in the context of contemporaneous and temporal aggregation. We illustrate the relevance of these theoretical results for the empirical analysis of time series. Using Italian data, we find that multivariate and univariate models extract similar core inflation measures when analyzing the moderate-low inflation period. In contrast, the two competing models yield different trends when modeling the Great Inflation period.
