Competing engines of growth: Innovation and standardization

We study a dynamic general equilibrium model where innovation takes the form of the introduction of new goods whose production requires skilled workers. Innovation is followed by a costly process of standardization, whereby these new goods are adapted to be produced using unskilled labor. Our framework highlights a number of novel results. First, standardization is both an engine of growth and a potential barrier to it. As a result, growth is an inverse U-shaped function of the standardization rate (and of competition). Second, we characterize the growth and welfare maximizing speed of standardization. We show how optimal protection of intellectual property rights affecting the cost of standardization vary with the skill-endowment, the elasticity of substitution between goods and other parameters. Third, we show that, depending on how competition between innovating and standardizing firms is modelled and on parameter values, a new type of multiplicity of equilibria may arise. Finally, we study the implications of our model for the skill premium and we illustrate novel reasons for linking North–South trade to intellectual property rights protection.     

Lab and framed lab versus natural experiments: Evidence from a risky choice experiment

Some recent papers have studied data from TV game shows to examine the behaviour of individuals towards risk. It is generally agreed that data from these shows are useful in detecting individual risk aversion in the field, with both “real life” subjects and incentives. Field experiments also include some interesting reality features that could affect individuals’ behaviour and possibly lead to different findings. This paper aims at investigating lab versus field evidence in risk taking attitudes, especially controlling for framing effects. To assess whether the behaviour of subjects in the field is consistent with that of experimental subjects, we designed an experiment to mimic (with experimental rewards and subjects) the rules of a well-known Italian TV game show, Affari Tuoi, in two different settings: a traditional lab setting, where the game was played individually (109 subjects) (Treatment 1); and a framed lab, in which the experiment was replicated in the Italian public television (RAI) studio where the show was actually recorded, with a smaller sample of undergraduate students (33) and in the presence of an audience (Treatment 2). Our comparison between the two different settings aims at establishing whether the presence of an audience, or of a situation that reproduces the stress that contestants must experience in the TV studio, can affect experimental subjects’ choices. We did not find any significant evidence of framing effects: students behave in a similar way in the two lab settings, responding essentially to incentives. Comparing the risk attitudes shown by experimental subjects in the two lab treatments with those exhibited by the contestants in the field, we found that contestants in the TV show are generally more risk averse than students in the lab.     

The Inflationary Consequences of a Currency Changeover on the Catering Sector: Evidence from the Michelin Red Guide*

This paper examines the inflationary consequences of a currency changeover in the catering market. Empirical evidence from the Michelin Red Guide shows that: (i) differently from restaurants in non‐euro countries, restaurants in the euro area experienced abnormal price increases just after the changeover; and (ii) among restaurants in the euro area, tourist restaurants are responsible for most of the abnormal price increases. These results suggest that proposed explanations for the changeover effect, such as menu adjustment and rounding up, are only part of the story. We present a simple model of the catering market that is consistent with the evidence.

Quantiles, expectiles and splines

A time-varying quantile can be fitted by formulating a time series model for the corresponding population quantile and iteratively applying a suitably modified state space signal extraction algorithm. It is shown that such quantiles satisfy the defining property of fixed quantiles in having the appropriate number of observations above and below. Like quantiles, time-varying expectiles can be estimated by a state space signal extraction algorithm and they satisfy properties that generalize the moment conditions associated with fixed expectiles. Because the state space form can handle irregularly spaced observations, the proposed algorithms can be adapted to provide a viable means of computing spline-based non-parametric quantile and expectile regressions.     

Examining the Interaction between Saving and Contributions to Personal Pension Plans: Evidence from the BHPS*

This paper analyses the effects of social security reforms on saving in Britain. We use the British Household Panel Survey to investigate the interactions between voluntary additional contributions to personal pension plans (PPP) and saving in conventional forms. In particular, we test whether contributions to the PPP crowd out saving or constitute additional saving. Results suggest that not only have private pension schemes not crowded out private saving, but actually they have increased it too.     

Using users: When does external knowledge enhance corporate product innovation?

Prior research on corporate innovation highlights the importance of accessing external knowledge from other firms and universities. However, survey evidence indicates that product users are perhaps the most important source of external knowledge. We build on existing theory to identify the conditions under which user knowledge contributes to corporate innovation and when the benefits will be greatest. Using a panel dataset of medical device companies and their collaborative efforts with innovative physicians, we find evidence that inventive collaborations with users enhance corporate product innovation and that the benefits are greatest in new technology areas and in the generation of radical innovations.

The Curse of Being Landlocked: Institutions Rather than Trade

This article revisits the long‐term economic effects of being landlocked. The conventional wisdom, which also prevails in policy circles, is that landlockedness hurts development by reducing trade. Gravity models of bilateral trade seem to confirm this view. However, there is no evidence in cross‐country data of a systematic relationship between landlockedness and country's trade to GDP ratio. Drawing on this stylised fact, the paper explores the possibility that landlockedness might affect GDP independently from its effect on trade. Theoretical considerations suggest that institutional quality could be a relevant transmission mechanism. The estimation of a system of three equations confirms that landlockedness has a negative effect on GDP and that this negative effect is transmitted through institutions rather than trade. Moreover, after controlling for the transmission via institutions and trade, landlockedness has a further negative effect on GDP. These findings call for a review of the policy approach to the development of landlocked countries.     

An integrated competency‐based approach to management education: an Italian MBA case study

Several studies have analysed the impact of competency‐based methodologies on human resource management, with special emphasis on their applications to management education and development. As concerns management education, however, these studies have usually focused on one or few separate aspects, never proposing a consistent application of competency‐based methodologies throughout the entire educational process. This paper shows how it is possible to design, deliver and monitor a management education programme that uses, in an integrated manner, a multiplicity of competency‐based tools in all the stages of the process, and discusses the application of such an integrated approach to an Italian MBA programme. This study provides a multiple constituency framework that integrates educational institutions, students and the companies that hire them in the design, implementation and control of effective, competency‐based, management education.
