Involuntary unemployment and inventories: An exploratory model of equilibrium and pure competition

We build up a model where the combination of labor supervision costs and non-uniform tastes results in a perfect-foresight equilibrium with positive involuntary unemployment and inventories even when prices and wages are assumed to be perfectly flexible. We show that the model could explain a positive association between the real wage and the level of employment (contrary to the standard post-Keynesian model), and a negative one between inventories and employment.     

Synchronization and diversity in business cycles: a network analysis of the European Union

In this article, we use a correlation matrix and its internal networks to analyse business cycle synchronization across Europe since 2000. This methodology allows us to summarize individual country interactions and co-movements while also capturing the existing heterogeneity of connectivity within the European economic system. Our results indicate that synchronization of the euro zone countries remained stable from 1999 until the current financial crisis, after which co-movements increased sharply and synchronization rose to the highest in the time sample. By endogenously identifying clusters of countries with close connections in their business cycle, we also refute the commonly accepted notion of identifiable core and peripheral euro zone countries.     

Production targets

We analyze a dynamic model of quantity competition, where firms continuously adjust their quantity targets, but incur convex adjustment costs when they do so. Quantity targets serve as a partial commitment device and, in equilibrium, follow a hump‐shaped pattern. The final equilibrium is more competitive than in the static analog. We then use data on monthly production targets of the Big Three U.S. auto manufacturers and show a similar empirical hump‐shaped dynamic pattern. Taken together, this suggests that strategic considerations may play a role in setting auto production schedules, and that static models may misestimate the industry's competitiveness.     

Measuring Global Economic Interdependence: A Hierarchical Network Approach

This paper investigates the business cycle co‐movement across countries and regions since 1950 as a measure for quantifying the economic interdependence in the ongoing globalisation process. Our methodological approach is based on analysis of a correlation matrix and the networks it contains. Such an approach summarises the interaction and interdependence of all elements, and it represents a more accurate measure of the global interdependence involved in an economic system. Our results show (1) the dynamics of interdependence has been driven more by synchronisation in regional growth patterns than by the synchronisation of the world economy, and (2) world crisis periods dramatically increase the global co‐movement in the world economy.     

Governance of flexible mobile service platforms

Development of advanced mobile Internet services requires flexible service platforms. Every service offering needs generic functionalities like security, billing and customer data management. Such functionalities used to be integrated in the mobile network infrastructure but are now offered by competing service platforms. Future service platforms might be offered by operators but can also be embedded in the mobile phone or at the systems of the service providers. Studying flexibility of service platforms requires technological as well as strategic analysis, and should take into account the perspective of multiple stakeholders. Where to locate service platforms is not just a technological matter as it greatly influences flexibility of both service providers and end-users. This paper analyzes how various service platform technologies that are located at operators, mobile phone and service providers influence flexibility. We find that no single service platform offers superior flexibility to both service providers and end-users.

On the optimal acquisition of foreign capital through investment of oil export revenues

The subject of the paper is the optimal policy for a national monopoly to follow when the product exported is an essential input for production in the importing country and the exporter wishes to invest the proceeds in the purchase of claims on the capital stock of the importer. A number of alternative optimal solutions are compared with the conventional monopoly solution. The focus is on the deviations from this solution that are induced by the actual or desired ownership of capital in the importing country by the exporter.
