In this note we show that the claim from Chen et al (2005) that their model generates an endogenous markup is incorrect. This is not only a nomenclature issue: using the �fixed markup which we show to be the only one consistent with the structure of the model implies the main conclusions in...

We consider an overlapping generations model in which public spending directly contributes to grow up productivity as Barro (1990) and a government comforts the constant spending-GDP and debtspending ratio rules. We analyse policy effects on fiscal sustainability, growth rate and welfare. This...

This paper aims at analysing the methodology used for financing large infrastructure projects in Italy. In particular, it focuses on the Italian highway sector, where in the last years many projects have been launched using new financial instruments. The paper discusses three of these...

This study explores the ‘affordability’ of development targets in six key sectors (health, education, water and sanitation, agriculture and infrastructure), by means of an empirical study examining sectoral expenditure in five low income case study countries in sub-Saharan Africa (Ethiopia,...

This article investigates the contribution of regions to aggregate growth. We find a great degree of heterogeneity in the performance of Territorial Level 3 ( TL3) regions of the OECD (Organization for Economic Cooperation and Development). The regional contributions to aggregate growth follow a...

This paper investigates the impact of regional sectoral diversity on regional employment growth in Italy over the period 1991-2001. Assuming that externalities may be stronger between industries selling similar products or sharing the same skills and technology (i.e. related industries), we...

This paper provides an analysis of the impact of the German “Joint Task for the Improve-ment of Regional Economic Structures” (GRW) on labour productivity growth of 225 German labour market regions for the period 1994 to 2006. The empirical regression approach builds on a “Barro-type”...

The principle aims of regional policy can be encapsulated in terms of ‘spatial equity’ and ‘economic efficiency’. Establishing the relation between these two aims is of fundamental importance. Conventionally, however, it is assumed that there is a conflict or a ‘trade-off’ between...

This paper makes an attempt to estimate the impact of regional variety and trade linkages on regional economic growth by means of export and import data by Italian province (NUTS 3) and sector (3-digit) for the period 1995-2003. Our results show strong evidence of related variety contributing to...

Because micropolitan areas have only relatively recently been defined, little is known about their comparative economic performance. Part of the interest in micropolitan areas stems from the successful ones often growing to become metropolitan areas. This paper examines micropolitan area growth...
