The spatial sorting and matching of skills and firms

Abstract .  In this paper we make use of a matched employer-employee database for Italy to look at the spatial distribution of wages. Using this rich database we aim to open up the black box of agglomeration economies exploiting the micro dimension of interaction among economic agents, both individuals and firms. We provide evidence that firm size and, especially, skills are sorted across space and account for a large portion of the spatial wage variation. Our data also support the assortative matching hypothesis, which we show not to be driven by co-location of good workers and firms. Finally, we point out that assortative matching is negatively related to local market size.     

“Rules of thumb” for sovereign debt crises

This paper investigates the economic and political conditions that are associated to the occurrence of a sovereign debt crisis. We use a new statistical approach (Classification and Regression Tree) that allows us to derive a collection of “rules of thumb” that help identify the typical characteristics of defaulters. We find that not all crises are equal: they differ depending on whether the government faces insolvency, illiquidity, or various macroeconomic risks. We also characterize the set of fundamentals that can be associated with a relatively “risk-free” zone. This classification is important for discussing appropriate policy options to prevent crises and improve response time and prediction.     

R&D competition, absorptive capacity, and market shares

This paper deals with an oligopolistic industry where firms are engaged in cost-reducting R&D activity to maximize their market shares. The existence and uniqueness of a feedback-Nash-optimal R&D strategy for each firm are discussed. Our simulations highlight that variations in spillovers hardly influence the firms' R&D investment, if their absorptive capacities to exploit extramural knowledge depend on their R&D efforts. Moreover, extramural knowledge cannot completely replace in-house R&D. However, a high level of public R&D favors the firm with the most restrictive R&D expenditure constraint and/or with the lowest initial R&D stock, provided it invests in R&D.     

Technology adoption and accumulation in a vintage-capital model

We present a model of capital accumulation and technology adoption in a vintage-capital framework. The model is an infinite-horizon/infinite-dimensional optimal control model: the firm employs a continuum of technologies (a continuum of heterogeneous capital goods). Capital goods are technology specific, their technology is related to vintage and technology progress. The entrepreneur maximizes the profits obtained by employing a continuum of technologies under the assumption of constant returns to scale and bearing adjustment costs for gross investments. The diffusion of a new technology is established by allowing the entrepreneur to invest in vintage capital goods.     

Identification and dimension of the NAIRU

In this paper, we have re-examined the identification of the NAIRU and presented a well-defined reduced form for analysing the equilibrium unemployment rate, using a cointegrated VAR model. We have stated that the NAIRU estimates using the conventional reduced form (or Phillips curve) models are misleading since the natural rate of unemployment cannot be considered as a fixed point calling for the ceteris paribus assumption for all the data involved. This implies that the NAIRU estimates are unable to provide valuable information on the labour market status.     

Uncertain prospects for ISDN : A Spanish view

Operators of telecommunications networks, network systems manufacturers and policy markers have placed their hopes on ISDN for a stable and brilliant telecommunications future. However, non-voice service providers, customer premises equipment manufacturers and large users fear that the envisaged network approach will not serve their future requirements. Telecommunications networks will have a strategic importance in national economic development. It is important not to constrain that development by tying them to an inappropriate and inflexible network structure. In this article the uncertainties of the ISDN network are reviewed, questions are raised and the evolution of the network is examined, from the perspective of the actors involved in the sector: large users, equipment manufacturers, policy makers and service providers.     

The Spanish telecommunications sector in search of its future

The internationalization of telecommunications services and products, together with Spain's entry into the European Economic Community, have created increased interest in the Spanish national telecommunications system. In this article are described the current situation for Spanish telecommunications, and the initial actions being taken to adapt its structure and legal framework to the new environment. Attempts are being made to provide it with enough flexibility to evolve in the most suitable direction for the country to participate in the movements happening on the world market.     

Homo Oeconomicus Returns: Neoliberalism,Socio-Political Uncertainty and Economic Policy

The aim of this paper is to discuss how neoliberal policy is changing the way people conceive of the economy and of society. After a brief outline of the main features of neoliberal policies, it argues that neoliberalism does not consist in a mere set of wrong economic theories or in the plain reflection of vested interests. It is a full-fledged view of how society should be organized. The paper then argues that these policies and the ideology that backs them up determine major institutional changes which affect economic, social and polity-related variables but also the general understanding that peo-ple have of the economy and of society. More specifically, it enhances uncertainty about one’s future and favors a non-solidaristic view of social relations. These changes tend to prejudge the effectiveness of employment policies and to reinforce the neolib-eral consensus. The conclusion is that it is not possible to conceive of an appropriate macroeconomic policy unless institutional changes are taken into account that trans-cend macroeconomics as such and re-establish the social underpinnings for that policy. These include changes in how the economy is coordinated but also changes in the bar-gaining power of workers and citizens relative to business.     

Contaminant,Commodity and Fuel: A Multi-sited Study of Waste's roles in Urban Transformations from Italy to Austria

This article traces the flow of municipal solid waste from southern Italy through a waste-to-energy facility and district heating system in Austria, examining the roles that waste's transformation from contaminant to commodity to fuel plays in interconnected, distributed, and contested urbanization processes. It contends that, while metabolic circulation hides socioecological costs in one place to facilitate valorization in another, specific spatial configurations emerge through territorialization—of waste economies, in this case—providing the spatial base to realize metabolic flows and to anchor political narratives. A decisive effect is that certain patterns of urbanization become locked-in, impeding alternative metabolic transitions and spatial configurations. Attending to the coproduction of three sites—Naples, Italy; Zwentendorf, Austria; and St Pölten, Austria—through the circulation and transformation of waste and energy the article provides an empirical multi-sited case study of a political ecology of urbanization.     

Does it really hurt? Making sense of varieties of anger

While research has shown that consumer anger causes a range of negative consequences, the conceptualization and measurement of this emotion remain inconsistent. Some studies link anger to consumer revenge motivated by a desire to hurt the company, while others associate anger with a desire to cooperate with the company. This inconsistency is caused by the fact that anger is a broad label used to refer to almost any brand failure. We argue that, rather than considering anger as a single construct, scholars should distinguish between a supportive facet of anger, which comprises feelings of annoyance, frustration and other mild negative feelings, and a vindictive facet of anger, which comprises feelings of intense anger, rage, and outrage. These two facets of anger reconcile divergent arguments presented in past research. Research benefits from moving beyond the generic label of anger to consider supportive and vindictive facets of anger that influence consumers' reactions under different circumstances. Only vindictive anger prompts consumers to take revenge and punish the company for unfair treatment. Supportive anger triggers instead a desire to solve the problem by cooperating with the company. This study presents important managerial implications for assessing and managing feelings of anger following brand failures.
