“To Bid or Not to Bid, This is the Question: The Italian Experience in Competitive Tendering for Local Bus Services”

Competitive tendering is a popular mechanism for the provision of local bus services when a major objective is subsidy savings. Despite uncertainties in the legal rules some competitive tendering was implemented in Italy since 1998. The evidence so far is that participants were limited in number, the incumbents were almost everywhere able to gain the franchise, whilst subsidy savings were in many cases negligible. If some “political” conditions favouring more effective tendering procedures are not fulfilled, other regimes should be considered in order to obtain substantial subsidy savings.Local bus services; Competitive Tendering

Challenging the Scientific Foundations for an IUCN Red List of Ecosystems

The International Union for Conservation of Nature (IUCN) is currently discussing the development of a Red List of Ecosystems (RLE) that would mirror the categories and criteria used to assess the conservation status of species. The suggested scientific foundations for the RLE are being considered by IUCN for adoption as the backbone of the RLE. We identify conceptual and operational weaknesses in the draft RLE approach, the categories, and criteria.While species are relatively well-described units, there is no consistent means to classify ecosystems for assessing conservation status. The proposed RLE is framed mostly around certain features of ecosystems such as broad vegetation or habitat types, and do not consider major global change drivers such as climate change. We discuss technical difficulties with the proposed concept of ecosystem collapse and suggest it is not analogous to species extinction. We highlight the lack of scientific basis for the criteria and thresholds proposed by the RLE, and question the need to adopt the structure of the Red List of Species for an RLE. We suggest that the proposed RLE is open to ambiguous interpretations and uncertain outcomes, and that its practicality and benefit for conservation should be carefully evaluated before final approval

Do Competition and Ownership Matter? Evidence from Local Public Transport in Europe

This paper investigates how the ownership and the procedure for the selection of firms operating in the local public transport sector affect their productivity. In order to compare different institutional regimes, we carry out a comparative analysis of 72 companies operating in large European cities. This allows us to consider firms selected either through competitive tendering or negotiated procedures. The analysis of the data on 77 European firms over the period 1997-2006 indicates that firms operate under constant returns to scale. Retrieving the residuals we obtain a measure of total factor productivity, which we regress on firm and city characteristics. We find that when firms are totally or partially in public hands their productivity is lower. Moreover, firms selected through competitive tendering display higher total factor productivity.Local Public Transport, Public Ownership, Translog Production Function

Labour market imperfections, "divine coincidence" and the volatility of employment and inflation

The dynamic general equilibrium model with hiring costs presented in this paper delivers involuntary unemployment in the steady state as well as involuntary fluctuations in unemployment. The existence of hiring friction introduces externalities that, in turn, entail the breakdown of the "divine coincidence" without assuming real wage rigidity. Our model with labour market imperfections outperforms the standard NK model as for the persistence of responses to monetary shocks. The model also allows for an analysis of the volatility of economies, differing in their "degrees of labour market rigidity". It turns out that "rigid" economies exhibit less unemployment volatility and more inflation volatility than "flexible" economies.Hiring Costs, Wage Bargaining, Output Gap, New Keynesian Phillips Curve

Use of satellite images for broad-scale modelling of conservation areas for wolves in the Carpathian Mountains, central Europe

This study analysed the spatial structure of the Carpathian Mountains, in Central Europe, considering it a unit that extends across national boundaries, and assessing the suitability of areas were wolves could be conserved. Physical characteristics of the area were extracted from NOAA-AVHRR NDVI. A set of 9 images from different periods of the year was used to parameterise the phenological variability of the area. Digital maps of road networks, human settlements and a DEM were integrated in a GIS. Locations of wolf presence were used to extract “optimal” environmental characteristics that served as reference for estimating the degree of suitability over the whole area. Results show that most of the Carpathian Mountains are highly suitable for the wolf and that highly suitable areas are actually inhabited by the present population of wolf. These are also the area most phenologically stable

Unemployment, inflation and monetary policy in a dynamic New Keynesian model with hiring costs

The dynamic general equilibrium model with hiring costs presented in this paper delivers involuntary unemployment in the steady state and involuntary fluctuations in unemployment. After calibrating the model, through simulations we are able to show that our model with labour market imperfections outperforms the standard NK model as for the persistence of responses to monetary shocks. Besides, the model can be easily used to assess the impact of different market imperfections on both the steady state and the dynamics of the economy. We are also able to show how two economies, differing in their “degrees of imperfection”, react to policy or non policy shocks: a rigid economy turns out to be less volatile than a flexible economy. Something that reflects the actual experience of the US (flexible) and European (rigid) economies.Hiring Costs, Wage Bargaining, Output Gap, New Keynesian Phillips Curve, Monetary Policy

Revisiting the past as a means of validation: bridging the myth of the Resistance and the satire of the Economic Miracle in two comedies "Italian style"

Many commedia all’italiana filmmakers have acknowledged the neorealist mode of production as a source of inspiration for their practice of pursuing social criticism in realistic and satirical comedies between 1958 and 1977. The detractors of the genre, however, have accused the commedia filmmakers of “diluting” the neorealist engagement to a simple description of the habits of Italians during the Economic Miracle, a description which threatened to encourage, through the casting of popular stars, the cynical attitude it sought to satirise. In this article, I shall discuss how two commedia all’italiana directors, namely Dino Risi and Ettore Scola, produced two significant commedie, respectively Una vita difficile (1961) and C’eravamo tanto amati (1974), which bridged the Resistance setting, associated with neorealism,and the Economic Miracle setting of most commedie all’italiana in order to reaffirm their neorealist roots, thus revisiting the past as a response to the critical underestimation from which their cinematic practice suffered
