A two-step approach to account for unobserved spatial heterogeneity

A two-step approach to account for unobserved spatial heterogeneity. Spatial Economic Analysis. Empirical analysis in economics often faces the difficulty that the data are correlated and heterogeneous in some unknown form. Spatial econometric models have been widely used to account for dependence structures, but the problem of directly dealing with unobserved spatial heterogeneity has been largely unexplored. The problem can be serious particularly if we have no prior information justified by economic theory. In this paper we propose a two-step procedure to identify endogenously spatial regimes in the first step and to account for spatial dependence in the second step. This procedure is applied to hedonic house price analysis.     

Fiscal consolidations and public debt in Europe

The objective of this paper is to gain insights into the relationship between deficit-reducing policies and the evolution of the debt/GDP ratio. We consider past events of fiscal consolidation in a selected group of EU countries and check what is the associated change of the debt/GDP ratio both from a short- and medium-term perspective. In the analysis, we also differentiate between tax-based and savings-based fiscal consolidations and the pre-Euro and Euro periods. Our results point towards a positive short-term effect, while the medium-term effect turns out to be negative. Savings-based fiscal consolidations result to be less negative on the DGR evolution than tax-based ones. The Euro’s introduction seems not to have altered significantly the relationship studied.     

Making the most of your firm's capabilities

In this Executive Digest, we make the case that aggregate individual expertise as a resource and intrinsic capability of the firm are hidden in plain sight, or worse, are assumed to exist where they do not. With high levels of complexity, business diversity, and number of geographical locations, the issue becomes even more acute. We propose strategic resource mapping (SRM) as a methodology designed to provide top managers with a rapid, comprehensive, and penetrating assessment of a firm's ‘meta-capability’: an actionable overview of the capabilities that exist within the firm. Based on multiple successful implementations, we describe the key features of SRM and provide several illustrations.     

Old and new partners: Similarity and competition in the EU foreign agri-food trade

This paper analyses the trade relationships among the EU-15 members and some emerging partners: the NMS, Turkey and China. The EU expansion to include 10 new countries has modified quite remarkably the features of agri-food trade in Europe. Some of the NMS, such as Poland, Hungary and the Czech Republic, significantly contribute to the international agri-food trade and, since the beginning of the process of EU accession, they have modified dramatically the exchanges with the EU-15. More recently, other countries such as Turkey and China have established new relationships with the EU. Turkey is a large Mediterranean country and, as a candidate to the EU accession, enjoys a differential treatment in the agri-food trade relationships with the EU. China can be considered as a new international competitor, growing at faster pace after having joined the WTO and increasing its agri-food trade exchanges with the EU. The analysis will focus on the measurement of the similarity of the agri-food exports of Italy and the remaining EU-15 member States with the new partners entering the EU-15 market. It will be carried out with the support of three different indicators: the export structure similarity index (ES), the product similarity index (PSI) and the quality similarity index (QSI), using the Eurostat database with an eight “digit” merchandize disaggregation and with reference only to agri-food exchanges. Results will indicate that there is little similarity, especially when a comparison is made between the exports of the EU-15 countries to the EU market. Moreover, quality remains a crucial factor for Italian and European agri-food products when competing with external products.     

Financial stress and economic contractions

This paper examines why some financial stress episodes lead to economic downturns. The paper identifies episodes of financial turmoil in advanced economies using a financial stress index (FSI), and proposes an analytical framework to assess the impact of financial stress – in particular banking distress – on the real economy. It concludes that financial turmoil characterized by banking distress is more likely to be associated with deeper and longer downturns than stress mainly in securities or foreign exchange markets. Economies with more arm's-length financial systems seem to be more exposed to contractions in activity following financial stress, due to the greater procyclicality of leverage in their banking systems.     

Alcune nuove nozioni di semicontinuità per multifunzioni

Si introducono nuove nozioni di semicontinuità per multifunzioni che estendono quelle classiche relative alle funzioni. Inoltre, utilizzando tali generalizzazioni si studia la semicontinuità superiore di una funzione del tipo inf _v∈N(u) f(u, v). Infine, si applicano i risultati ottenuti ad un problema di scelta del prezzo.

Summary In this paper new notions of semicontinuity for multifunctions are introduced; this definitions extend the classical notions concerning the functions. Moreover, using this generalizations, the upper semicontinuity of a function like inff(u, v) is studied. In the last section the results obtained are applied to av∈N(u) problem of selection price.

     

Interregional Migration of Human Capital and Unemployment Dynamics: Evidence from Italian Provinces

Since the mid‐1990s interregional migration flows in Italy have dramatically increased, especially from the South to the North. These flows are characterized by a strong component of human capital, involving a large number of workers with secondary and tertiary education. Using longitudinal data for the period 2002–2011 at NUTS‐3 territorial level, we document that long‐distance (i.e., South‐North) net migration of high‐skill workers has increased the unemployment at origin and decreased it at destination, thus deepening North–South unemployment disparities. On the other hand, long‐distance net migration of low‐skill workers has had the opposite effect, by lowering the unemployment at origin and raising it at destination. Further evidence also suggests that the diverging effect of high‐skill migration dominates the converging effect of low‐skill migration. Thus, concerns for an ‘internal brain drain’ from Southern regions look not groundless.
