This paper investigates 53 public HEIs in Turkey between 2005 and 2010 including 5 full academic terms to estimate both their cost frontier and inefficiencies. The initial findings of six different models imply that Turkish universities perform quite well concerning their overall efficiency...

British cities are becoming more culturally diverse, with migration a main driver. Is this growing diversity good for urban economies? This paper explores, using a new 16-year panel of UK cities. Over time, net migration affects both local labour markets and the wider economy. Average labour...

Analytical asymptotic local power functions are employed to study the effects of general form short term serial correlation on �fixed-T panel data unit root tests. Two models are considered, one that has only individual intercepts and one that has both individual intercepts and individual...

In this paper we suggest panel data unit root tests which allow for a structural breaks in the individual effects or linear trends of panel data models. This is done under the assumption that the disturbance terms of the panel are heterogeneous and serially correlated. The limiting distributions...

This paper analyses the properties of the fixed-effects vector decomposition estimator, an emerging and popular technique for estimating time-invariant variables in panel data models with unit effects. This estimator was initially motivated on heuristic grounds, and advocated on the strength of...

Theoretical models point at various channels of the impact of inflation on corporate investment. This article attempts to answer the question what are the direction and strength of this possible impact examining the relationship between corporate investment and inflation on the sample of 21 OECD...

The aim of this paper is to explore the impact of intra- and inter-industry spillover components on productivity of large International firms. We use data from all EU R&D investment scoreboards editions issued every year until 2011 by the JRC-IPTS (scoreboards). The analysis is based upon a new...

We estimate the set of panel and spatial panel data models of employment and investments for 379 Polish counties over the period 2003-2012. We take advantage of a unique firm-level dataset for Polish Special Economic Zones (SSEs), which includes about 30,000 observations. We find that SSEs have...

The aim of this paper is to analyze the relationship between inter-industry, intra-industry and inter-regional clustering and demand for labor by companies in Portugal. Is expected at the outset that there is more demand for work where the agglomeration is greater. It should be noted, as a...

With this work we try to analyse the agglomeration process in the Portuguese regions, using the New Economic Geography models. In these models the base idea is that where has increasing returns to scale in the manufactured industry and low transport costs, there is agglomeration. Of referring,...
