Entry, Prices, and Investment in Regulated Industries

The paper studies how the optimal regulatory policy is affected by the possibility of unregulated firms entering the market. In such cases, the regulator may prefer to limit price and cost reductions in the regulated incumbent. The extent to which this happens is shown to depend on the extent of the regulator's commitment: if it commits to a chosen policy, then the market outcome following entry is less competitive than it would be without commitment: price and production costs are both higher. We also show that, unlike the natural monopoly case, incentives for cost reducing investment are stronger when the regulatory policy has a short regulatory interval.     

Bayesian inference in cointegrated systems

In this paper I deal with Bayesian methods for conducting inference on important features of (potentially) cointegrated VAR models involving I(1) variables. Firstly, (informal) inference is made on the cointegrating rank of the system. Secondly, posterior analysis is used to verify the validity of over-identifying restrictions on the cointegration parameters. Thirdly, posterior distributions are obtained for impulse response functions and predictive densities at different horizons. The relevant posterior distributions are obtained by means of Monte Carlo integration. The analysis is based on the use of simple weakly informative priors. Two applications on simulated data and on the Danish money demand data are presented.     

Monetary Union, institutions and financial market integration: Italy, 1862–1905

Years into the single currency, EMU financial markets are not fully integrated. We argue that the phenomenon can be better understood by looking at financial markets’ behavior in the wake of Italy’s monetary unification (1862). Variables such as the spread of the telegraph, trade volumes, and the diffusion of the ‘single currency’ fail to explain why it took 25 years for prices across regional stock exchanges to converge. A single Italian financial market appeared only when the State prevailed upon local vested interests by enforcing nation-wide financial market legislation.     

An item response theory approach to constructing and evaluating brief and in-depth financial literacy scales

We applied item response theory (IRT) to construct and evaluate new brief and in-depth financial literacy scales. A survey of a UK adult sample (N = 589) included 50 questions to assess knowledge about managing financial resources and competence in using personal finance-related information—including five widely used items, on interest rates, inflation, investment diversification, mortgages and bonds. IRT applied to a scale of these items identified some limitations, overcome via further iterations to construct a new brief scale with sound psychometric properties. IRT was then applied iteratively to our pool, resulting in an in-depth, 20-item scale, also psychometrically sound, covering four broad financial domains: everyday money transactions; the concept of money; borrowing; and saving and investment. Parallel 10-item sub-scales were also evaluated. The validity of the new scales was demonstrated by regression analyses which found that, controlling for demographic variables, financial literacy predicted key indicators of financial well-being.     

Mercantilism: a materialist approach

ABSTRACT

Historians and economists have shown renewed interest in mercantilism over the last couple of years. From this interest, a dispute has arisen about whether mercantilism should be seen as an incoherent economic thought or if it is possible to ‘reconstruct’ its basic principles. In line with this latter attempt, this paper is intended to provide a materialist explanation for varying degrees of belief in shared mercantilist assumptions. My hypothesis is that belief in mercantilist assumptions is significantly dependent upon how economic and security issues materially interact in a given time and space, with uncertainty and insecurity profoundly favouring mercantilist dispositions in economic thought. To analyse this hypothesis, the paper sets the first steps for relating the credibility of mercantilism with changes in British economic and military history from the sixteenth to the nineteenth century. Section 3 presents ideas to further investigate this hypothesis. Section 4 concludes the paper.     

Economic impact of onabotulinumtoxinA for overactive bladder with urinary incontinence in Europe

Background: Overactive bladder (OAB) is a common condition that has a significant impact on patients’ health-related quality-of-life and is associated with a substantial economic burden to healthcare systems. OnabotulinumtoxinA has a well-established efficacy and safety profile as a treatment for OAB; however, the economic impact of using onabotulinumtoxinA has not been well described.

Methods: An economic model was developed to assess the budget impact associated with OAB treatment in France, Germany, Italy, Spain and the UK, using onabotulinumtoxinA alongside best supportive care (BSC)—comprising incontinence pads and/or anticholinergic use and/or clean intermittent catheterisation (CIC)—vs BSC alone. The model time horizon spanned 5 years, and included direct costs associated with treatment, BSC, and adverse events.

Results: Per 100,000 patients in each country, the use of onabotulinumtoxinA resulted in estimated cost savings of €97,200 (Italy), €71,580 (Spain), and €19,710 (UK), and cost increases of €23,840 in France and €284,760 in Germany, largely due to day-case and inpatient administration, respectively. Projecting these results to the population of individuals aged 18 years and above gave national budget saving estimates of €9,924,790, €27,458,290, and €48,270,760, for the UK, Spain, and Italy, respectively, compared to cost increases of €12,160,020 and €196,086,530 for France and Germany, respectively. Anticholinergic treatment and incontinence pads were the largest contributors to overall spending on OAB management when onabotulinumtoxinA use was not increased, and remained so in four of five scenarios where onabotulinumtoxinA use was increased. This decreased resource use was equivalent to cost offsets ranging from €106,110 to €176,600 per 100,000 population.

Conclusions: In three of five countries investigated, the use of onabotulinumtoxinA, in addition to BSC, was shown to result in healthcare budget cost savings over 5 years. Scenario analyses showed increased costs in Germany and France were largely attributable to the treatment setting rather than onabotulinumtoxinA acquisition costs.     

The productive effect of transport infrastructures: does road transport liberalization matter?

In this paper we analyze the impact of motorway networks on production for a panel of twenty one manufacturing and service sectors of eleven EU countries observed over the period 1980–2003. In particular, we analyze if the degree of regulation of the road transport sector affects the link between productivity and motorway infrastructures. Overall results suggest that output elasticity with respect to motorway is found to be lower for countries characterised by a high degree of entry barriers in the road transport sector. This result is found to be more evident for industries which rely more heavily on transport services.     

Misclassifications in financial risk tolerance

This paper analyses the empirical risk tolerance of individuals and the role of physiological measures of risk perception. By using a test that mimics the financial decision process in a laboratory setting (N?=?445), we obtained an ex-post empirical measure of individual risk tolerance. Predictive classification models allow us to evaluate the accuracy of two alternative risk-tolerance forecasting methods: a self-report questionnaire and a psycho-physiological experiment. We find that accuracy of self-assessments is low and that misclassifications resulting from questionnaires vary from 36 to 65%: individuals asked to self-evaluate their risk tolerance reveal a high probability of failing their judgement, i.e. they behave as risk takers, even if, before the task, they define themselves as risk averse (and vice versa). Conversely, when the risk-tolerance forecast is obtained from individuals’ physiological arousal, observed via their somatic activation before risky choices, the rate of misclassification is considerably lower (~17%). Emotions are confirmed to influence the financial risk-taking process, enhancing the accuracy of the individual risk-tolerance forecasting activity. Self-report questionnaires, conversely, could lead to inadequate risk-tolerance assessments, with consequent unsuitable investment decisions. Bridging these results from the individual to the institutional level, our findings should enhance cautiousness, among regulators and financial institutions, on the (ab)use of risk tolerance questionnaires as tools for classifying individuals’ behaviour under risk.     

Bayesian exploratory factor analysis

This paper develops and applies a Bayesian approach to Exploratory Factor Analysis that improves on ad hoc classical approaches. Our framework relies on dedicated factor models and simultaneously determines the number of factors, the allocation of each measurement to a unique factor, and the corresponding factor loadings. Classical identification criteria are applied and integrated into our Bayesian procedure to generate models that are stable and clearly interpretable. A Monte Carlo study confirms the validity of the approach. The method is used to produce interpretable low dimensional aggregates from a high dimensional set of psychological measurements.     

The Quest for Quality: A Quality Adjusted Dynamic Regulatory Mechanism

In situations where quality is fixed, the widely used RPI‐X regulatory mechanism has a number of desirable properties, such as convergence to a second best optimum. Theoretical analysis of this mechanism in the case of endogenous quality is limited and therefore regulators have typically imposed constraints on the firm's quality choice in ad hoc manners, either by mandating quality levels, or by including quality adjustment factors in the RPI‐X mechanism. In this paper, we construct the rigorous theoretical counterpart of these manners of including quality measures in the constraints faced by a regulated firm. This mechanism converges to second best optimum. It works by offering the firm trade‐offs between prices and qualities based on the choice it made in the previous period; however, reflecting the practical problem valuing quality, the informational requirement to select these trade‐offs appropriately is qualitatively stronger than in the fixed quality case. Moreover, even when the informational problem can be overcome, we identify a further potential pitfall in the approach taken in practice by regulators, and show that, in order to avoid it, the regulated firm should be subject to an additional constraint, which we label the distance constraint, and which can be interpreted as requiring the firms to choose prices and qualities within a band in every period.
