Market integration and market efficiency: The case of 19th century Italy

This paper examines market integration in Italy in the 19th century, focusing on wheat. Wheat prices converged well before political Unification (1859-1861) but the process halted during the 1860s only to resume in the 1870s and 1880s. The first wave of integration was caused mainly by improvements in market efficiency while the second wave owed much to a reduction in transport costs.     

Perceptions of predictive testing for those at risk of developing a chronic inflammatory disease: a meta-synthesis of qualitative studies*

Background: The availability of tests to predict the risk of developing chronic diseases is increasing. The identification of individuals at high risk of disease can trigger early intervention to reduce the risk of disease and its severity. In order for predictive tests to be accepted and used by those at risk, there is a need to understand people’s perceptions of predictive testing. Method: A meta-synthesis of qualitative research that explored patient and public perceptions of predictive testing for chronic inflammatory diseases was conducted. Studies were coded by researchers and patient research partners, and then organised into common themes associated with the acceptability or use of predictive testing. Results: Perceived barriers to predictive testing were identified, including a concern about a lack of confidentiality around the use of risk information; a lack of motivation for change; poor communication of information; and a possible impact on emotional well-being. In order to reduce these barriers, the literature shows that a patient-centred approach is required at each stage of the testing process. This includes the consideration of individual needs, such as accessibility and building motivation for change; readily available and easy to understand pre and post-test information; support for patients on how to deal with the implications of their results; and the development of condition specific lifestyle intervention programmes to facilitate sustainable lifestyle changes. Conclusion: Patients and members of the public had some concerns about predictive testing; however, a number of strategies to reduce barriers and increase acceptability are available. Further research is required to inform the development of a resource that supports the individual to make an informed decision about whether to engage in a predictive test, what test results mean, and how to access post-test support.     

Learning,market selection and the evolution of industrial structures

Industrial economics is a rich source of puzzles for economic theory. One of them — certainly the most discussed — regards the co-existence of firms (and plants) of different sizes, displaying rather invariant skewed distributions. Other puzzles, however, concern the sectoral specificities in industrial structures, the persistence of asymmetric corporate performances and the dynamics of entry and exit. The paper reports some preliminary results on evolutionary modeling of the links between the microeconomics of innovation, the patterns of industrial change and some observable invariances in industrial structures.First, the paper reviews a few of these empirical regularities in structures and in the patterns of change. Second, the paper discusses the achievements and limits of interpretations of the evidence based on equilibrium theories. Finally, it presents a model where these regularities are explained as emergent properties deriving from non equilibrium interactions among technologically heterogeneous firms. Moreover, simulation exercises show that also the intersectoral variety in the observed industrial structures and dynamics can be interpreted on the grounds of underlying specificities in the processes of technological learning — which is called technological regimes — and of the processes of market interactions — i.e. market regimes.This research has undertaken within an on going project sponsored by the Italian Research Council (CNR, Progetto strategico,Cambiamento tecnologico e sviluppo economico).

Common knowledge of the second kind

Although most of us know that human beings cannot and should not be replaced by computers, we have great difficulties saying why this is so. This paradox is largely the result of institutionalizing several fundamental misconceptions as to the nature of both trustworthy objective and moral knowledge. Unless we transcend this paradox, we run the increasing risks of becoming very good at counting without being able to say what is worth counting and why. The degree to which this is occurring is the degree to which the computer revolution is already over — and the degree to which we human beings have lost.I think that Aristotle was profoundly right in holding that ethics is concerned with how to live and with human happiness, and also profoundly right in holding that this sort of knowledge (practical knowledge) is different from theoretical knowledge. A view of knowledge that acknowledges that the sphere of knowledge is wider than the sphere of science seems to me to be a cultural necessity if we are to arrive at a sane and human view of ourselves or of science.

EMU Stability: Direct and Indirect Risk Sharing

Our paper aims to analyze the effectiveness of different risk-sharing mechanisms in providing stability to a monetary union. We select two stylized tools with extreme and opposite features. The first is an expansionary but conventional monetary policy that is used to help EMU’s most fragile member states manage their public debts; the second is a centralized fiscal policy that allows for the transfer of a portion of these public debts from EMU’s most fragile member states to those considered EMU’s “core”. By a stylized periphery-core model of a monetary union, we compare the strengths and weaknesses of these two tools in order to reach some welfare implications in terms of union stability.     

THE EFFECTS OF FISCAL POLICY SHOCKS IN SVAR MODELS: A GRAPHICAL MODELLING APPROACH

We apply graphical modelling (GM) theory to identify fiscal policy shocks in SVAR models of the US economy. Unlike other econometric approaches – which achieve identification by relying on potentially contentious a priori assumptions – GM is a data based tool. Our results are in line with Keynesian theoretical models, being also quantitatively similar to those obtained in the recent SVAR literature à la Blanchard and Perotti (2002) , and contrast with neoclassical real business cycle predictions. Stability checks confirm that our findings are not driven by sample selection.     

Firm Recruitment Behaviour: Sequential or Non‐sequential Search?

In the extensive job search literature, studies assume either sequential or non‐sequential search. This article introduces a novel method to test the hypothesis that firms search sequentially based on the relationship between the number of rejected job applicants and the number of filled vacancies. We distinguish between ten different search methods. For most search methods, including methods that rely on social networks and temporary help agencies, we find that sequential search cannot be rejected. However, when firms use advertising or public/private employment agencies, sequential search is rejected. Hence, we find that both forms of search are relevant for our understanding of the labour market. Further, the form of search is closely related to the search method used.     

Status Differentiation and the Protean Self: A Social-Cognitive Model of Unethical Behavior in Organizations

Based on social-cognitive theory, this article proposes a model that seeks to explain why high status organizational members engage in unethical behavior. We argue that status differentiation in organizations creates social isolation which initiates activation of high status group identity and a deactivation of moral identity. We further argue that high status group identity results in insensitivity to the needs of out-group members which, in turn, results in lessened motivation to self-regulate ethical decision making. As a result of this identity activation, we demonstrate how high status individuals will be more vulnerable to engaging in unethical activities. Individual-level moderators of the relationships are also discussed.
