Financial Integration and EMU’s External Imbalances in a Two-Country OLG Model

The pronounced increase in external imbalances in the European Economic and Monetary Union (EMU) during the years running up to 2008 is traditionally explained by financial integration through the common currency. This paper examines in a one-good, two-country overlapping generations’ model, with production, capital accumulation and public debt, the effects of financial integration on the net foreign asset positions of initially low-interest and high-interest rate EMU countries. We find that a lower savings rate and government expenditure quota, together with a higher capital production share in the latter can in fact be transformed into the observed external imbalances when interest rates converge.     

A Polarization Index for Overlapping Groups

The well‐known index of income bipolarization proposed by Wolfson (1994) requires two groups to be split according to the median income and, therefore, to be non‐overlapping. The aim of this paper is to propose a new polarization index in the spirit of the Wolfson index. It allows for any possible partition of the population in two or more (also overlapping) groups. The new index maintains the simplicity and immediate comprehension of the Wolfson index, though being much more flexible. An application is then provided for German and Italian income data.     

Measuring the Economic Effect of Global Warming on Viticulture Using Auction,Retail, and Wholesale Prices

In this paper we measure the effect of year-to-year changes in the weather on wine prices and winery revenue in the Mosel Valley in Germany in order to determine the effect that climate change is likely to have on the income of wine growers. A novel aspect of our analysis is that we compare the estimates based on auction, retail, and wholesale prices. Although auction prices are based on actual transactions, they provide a thick market only for high quality, expensive wines and may overestimate climate’s effect on farmer revenues. Wholesale prices, on the other hand, do provide broad coverage of all wines sold and probably come closest to representing the revenues of farmers. Overall, we estimate a 1°C increase in temperature would yield an increase in farmer revenue of about 30%.     

LA GESTION DES ENTREPRISES MUNICIPALES ENTRE MISSIONS DE SERVICE PUBLIC ET AUTONOMIE*

RESUME: Dam les Etats fédéraux, comme en Allemagne, les entreprises communales font partie intégrante de l'autommie de gestion locale par la mise à disposition d'une certaine infrastructure. Dernièrement, du côtéétatique et scientifique, on réclame de plus en plus une gestion de type commercial pour les entmprises publiques, et donc communales, d'infrastructure (approvisionnement, transport, évacuation). Cet article postule, à l'encore de ces tendances à l'uniformisation, de clairement marquer la distinction entre les fournisseurs privés et ceux du service public en raison de leur objet social différent. Même si la problématique de fond d‘une gestwn tutélaire d‘une entreprise est la même dam le secteur public que dans le secteur privé, le contnôle du comportement des gestwnnaires engagés est toutefois fort différent. La reddition de comptes de type commercial - qui est proposée également pour les entreprises publiques - permet plutôt de contnôler la gestion commerciale que cell d'un service public. Dam les deux cas, le contrôle comptable est complété par des dispositions organisationnelles. Dans le cas (d'infrastrmture), ces dispositions doivent satisfaire des exigemes différentes et nettement plus importantes que celles d'gpplication dans le secteur commercial en raison de la faible signification des résultats commerciaux dam le secteur public.     

Turning Agents into Psychological Principals: Aligning Interests of Non‐Owners through Psychological Ownership

Principals who delegate tasks to agents face the perennial challenge of overcoming agency problems. We investigate whether feelings of ownership among senior managers in the absence of formal ownership can align agents' interests with those of principals, thus turning agents into psychological principals. Using a moderated mediation model, we find that psychological ownership is positively related to company performance through the mediating effect of individual‐level entrepreneurial behaviour. We also find that the effect of psychological ownership on individual‐level entrepreneurial behaviour and, ultimately, company performance is weaker for high levels of monitoring compared to low levels. These findings offer important contributions to agency, psychological ownership, and entrepreneurship literatures.     

Expanding Socio-economics in Four Dimensions

Abstract

During the last decades the rapid progress in the fields of complex modelling and simulationor in the cognitive and the life sciences was not accompanied by a similar advancement of the socio-economic research tradition itself. Socio-economics as a hybrid field for the complex dynamics of modern societies across their micro-, meso- and macro-levels has still a long way to go in order to reach its full potential. The present article provides a general outline for expanding and advancing socio-economics along four different dimensions which should be able to produce a significant take-off for socio-economic theories, models, methods and mechanisms.     

Modeling Financial Integration,Intra-EMU and Asian-US External Imbalances

Intra-EMU external imbalances in the pre-crisis period up to 2008 are traditionally explained by EMU-oriented factors, e.g. euro-related financial integration. Chen et al. (2013) also emphasize external trade shocks, such as the competitive challenge of emerging Asia and oil exporters to EMU-periphery’s exports. Moreover, Asian-U.S. external imbalances are attributed to financial integration between East Asia and the USA in the aftermath of the East-Asian currency crises in the late 1990s (Angeletos and Panoussi 2011). Acknowledging these empirical facts this paper develops a Buiter (1981) three-country (EMU, Asia, US), two-region (EMU core, EMU periphery) OLG model to investigate the effects of both intra-EMU and Asian-U.S. financial integration on intra-EMU, Asian and U.S. external imbalances. We find that the widening of the intra-EMU external imbalances, in particular of trade imbalances, is related to the growth in Asian-U.S. imbalances and the dynamic inefficiency of the world economy, caused by excessive saving in Asia.
