Net Neutrality in Europe: Desperately seeking a market failure

Net Neutrality has become the focus of attention in the regulatory debate on the Internet. This article attempts to strip down the debate to its bare essential. It identifies two main types of Net Neutrality obligations that have been put forward and assesses what type of potential concerns they may be designed to address. It concludes that while some of these concerns may be important it remains doubtful (at least in Europe) that an ex ante per se rule, such as those proposed under the Net Neutrality term, is the best way to address them.     

A note on the exact transformation associated with the first-order moving average process

Exact analytical expressions for the transformation that can be used to transform a generalized regression problem into a simple regression problem are available for a variety of models. Such is the case, for instance, for purely heteroscedastic models, for the first-order Markov process and for error components models. For the first-order moving average process, on the other hand, the exact transformation has not yet been produced. This gap is filled in the present note.Implications for estimation and prediction are also considered.     

An analytic hierarchy process for ranking operating costs of low cost and full service airlines

This paper develops an application of the analytic hierarchy process to rank the operating cost components of full service and low cost airlines. It takes into account the financial balance sheets and answers to a questionnaire submitted to the managers of selected airlines. The results suggest that the analytic hierarchy process can be appropriately used to obtain the ranking of the costs taking into account different views: financial, management and operative. Rental, office equipment and other supplies costs show the highest importance in the cost ranking, both for full services and low cost airlines. The robustness of the results is tested by Monte Carlo analysis.     

Resources, innovation and growth in the global economy

The relative performance of open economies is analyzed in an endogenous growth model with asymmetric trade. A resource-rich country trades resource-based intermediates for final goods produced by a resource-poor economy. The effects of an increase in the resource endowment depend on the elasticity of substitution between resources and labor in intermediates' production. Under substitution (complementarity), the resource boom generates higher (lower) income, lower (higher) employment in the primary sector and faster (slower) growth in the resource-rich economy. In the resource-poor economy, the shock induces a higher (lower) relative wage and positive (negative) growth effects that are exclusively due to trade.     

Market makers as information providers: The natural experiment of STAR

Market makers are financial intermediaries who are supposed to provide additional liquidity, but do not have any information-related obligation. This paper studies the unique case of the Italian Stock Exchange, where market makers are also obliged to facilitate information disclosure about the firms they cover. We focus on a group of small/medium capitalization stocks (STAR) that are assigned a designated market maker (DMM) starting from 2001. We show that their liquidity requirements are not binding during the sample periods and that the main impact of DMMs' introduction is due to their obligations on information provision. We find that DMMs' activity as information providers reduces spread and price volatility, the probability of informed trading (PIN), and the adverse selection component of the spread. An event study provides evidence that the information released through DMMs is perceived as useful by market participants.     

The influence of the institutional context on corporate illegality

This paper examines the relationship between the institutional environment and sustained corporate illegality. We find that cognitive assumptions generate expectations that can, under specific circumstances, induce organizations to amplify illegal actions and that serve to lessen regulatory scrutiny. We also find that, once initiated, illegal actions can become hidden because of institutionalized practices that enable their concealment and that weaken the prospect of detection. These processes and effects are particularly noticeable in networks of professional regulators who become mutually over-confident and over-influenced by each other to the extent that their independent critical assessments and judgements are compromised. Mechanisms of mimetic herding and social humiliation compromise independence of judgement. Networks of interacting professionals are thus vulnerable to a collectively induced lowering of regulatory vigilance.     

Resource abundance, growth and welfare: A Schumpeterian perspective

This paper takes a new look at the long-run implications of resource abundance. It develops a Schumpeterian model of endogenous growth that incorporates an upstream resource-intensive sector and yields an analytical solution for the transition path. It then derives conditions under which, as the economy's endowment of a natural resource rises, (i) growth accelerates and welfare rises, (ii) growth decelerates but welfare rises nevertheless, and (iii) growth decelerates and welfare falls. Which of these scenarios prevails depends on the response of the natural resource price to an increase in the resource endowment. The price response determines the change in income earned by the owners of the resource (the households) and thereby the change in their expenditure on manufacturing goods. Since manufacturing is the economy's innovative sector, this income-to-expenditure effect links resource abundance to the size of the market for manufacturing goods and drives how re-source abundance affects incentives to undertake innovative activity.     

Industry and the Family: Two Engines of Growth

We generalize the class of endogenous growth models in which the scale of the economy has level rather than growth effects, and study the implications of different demographic and technological factors when both fertility choice and research effort are endogenous. The model incorporates two dimensions of technological progress: vertical (quality of goods) and horizontal (variety of goods). Both dimensions contribute to productivity growth but are driven by different processes and hence respond differently to changes in fundamentals. Specifically, while unbounded vertical progress is feasible, the scale of the economy limits the variety of goods. Incorporating a linearity in reproduction generates steady-state population growth and variety expansion. We thus have two engines of growth generating dynamics that we compare with observed changes in demographics, market structure, and patterns of growth. Numerical solutions yield the important insight that, while endogenous, fertility responds very little to industrial policies. Demographic shocks, in contrast, have substantial effects on growth.     

THE ESTIMATION OF HUMAN CAPITAL BY ADMINISTRATIVE ARCHIVES IN A STATIC AND LONGITUDINAL PERSPECTIVE: THE CASE OF MILAN

Abstract This paper focuses on the estimation of the latent variable human capital (HC) at disaggregated level (worker) by available routinely institutional data flows. In particular we utilize the Lombardy region administrative archive ‘Employment Centers of the Province of Milan’, collecting information about careers of workers in the private sector of the Milan area, and administrative flows collecting mandatory workers' individual income tax returns, filed with the National Internal Revenue Service. First, we propose and empirically estimate HC scores in a static (referred to 2004) framework, by means of a realistic measurement model within causal relationships among endogenous and exogenous (investment) HC indicators. Furthermore, the model also specifies a set of (concomitant) indicators that, not belonging to HC investment indicators, have causal impact on endogenous variables and on HC scores, too. Second, we propose a longitudinal analysis (period 2000–2004) aimed to investigate how workers' earned income growth rates vary over workers' educational levels and other personal characteristics. The empirical results of both analyses confirm the characteristics of the Italian job market, denoted by marked inequalities, and knowledge regarding the process of school to work transition, characterized by a weak incidence of education on longitudinal trajectories of earned income.     

Measuring the Returns to Networking and the Accumulation of Social Capital: Any Evidence of Bonding,Bridging, or Linking?

This article presents analyses of individual investment in social capital using both the British Household Panel Survey (BHPS) and the UK Time Use Survey (2000) (UKTUS). We suggest a general theoretical framework that could possibly explain individual investment in various forms of social networking. Measures of social capital are then constructed in an attempt to capture the extent of individual investment in bonding, bridging, and linking networks. These measures, together with other socioeconomic indicators, are used as explanatory factors in wage equations, estimated using ordered probit, OLS, and instrumental variable approaches. We are unable to identify any consistent returns from investment in bonding and bridging networks. In contrast, the evidence suggests that any returns to investment in the development of linking social capital simply derive from the positive signals that group membership may transmit to potential employers. Our results underline the contrast between studies that consider social capital as an attribute of communities, as opposed to individuals, in that we find a negative return to social activity at the level of the individual.
