  1. Disentangling the effect of waiting times on hospital choice: Evidence from a panel data analysis

    Lippi Bruni, Matteo; Ugolini, Cristina; Verzulli, Rosella
    This study examines the effect of waiting times on hospital choice by using patient-level data on elective Percutaneous Transluminal Coronary Angioplasty (PTCA) procedures in the Italian NHS over the years 2008-2011. We perform a multinomial logit analysis including conditional logit and mixed logit specifications. Our findings show the importance of jointly controlling for time-invariant and time varying dimensions of hospital quality in order to disentangle the effect of waiting times on hospital choice. We provide evidence that patients are responsive to changes in waiting times and aspects of clinical quality within hospitals over time, and estimate the trade-off that patients...

  2. Price Changes in Regulated Healthcare Markets: Do Public Hospitals Respond and How?

    Verzulli, Rossella; Fiorentini, Gianluca; Lippi Bruni, Matteo; Ugolini, Cristina
    This paper examines the behaviour of public hospitals in response to the average payment incentives created by price changes for patients classified in different Diagnosis Related Groups (DRGs). Using panel data on public hospitals located within the Italian region of Emilia-Romagna, we test whether a one-year increase in DRG prices induced public hospitals to increase their volume of activity, and whether a potential response is associated with changes in waiting times and/or length of stay. We find that public hospitals reacted to the policy change by increasing the number of patients with surgical treatments. This effect was smaller in the two years after the policy change than...

  3. Optimal Liability Design Under Risk and Ambiguity

    Franzoni, Luigi Alberto
    This paper develops an original mean-variance model able to capture the disposition of the parties towards both standard risk and ambiguity. Ambiguity arises when the causal link between conduct and harm is not univocal, as is frequently the case with toxic torts. Risk aversion and ambiguity aversion tend to have a similar impact on optimal liability rules if greater care reduces the ambiguity perceived by the parties, i.e. if safety and predictability go hand in hand. Strict liability dominates negligence when the injurer has lower degrees of risk and ambiguity aversion than the victim and can formulate less ambiguous estimates...

  7. Correlated accidents

    Franzoni, Luigi Alberto
    This paper investigates cases in which harms are statistically correlated. When parties are risk averse, correlation plays an important role in the choice between liability rules. Specifically, positively correlated harms favor a liability rule that spreads the risk over a multitude of parties, as in the negligence rule. Negatively correlated harms favor a liability rule that pools risks together, as in strict liability. The same applies when parties can purchase costly insurance (first party or third party). This policy recommendation is in line with current products liability law, which places design defects and warning failures under a de facto negligence...

  8. Dimensione d'impresa e conflittualità' nell'industria manifatturiera italiana

    Fiorentini, Gianluca; Prosperetti, Luigi
    Con questo paper si va ad analizzare la dimensione dell'impresa e la conflittualità presente all'interno dell'industria manifatturiera italiana.

  9. Conflittualita' e dimensione di impianto: sviluppi teorici e risultnze empiriche

    Fiorentini, Gianluca; Prosperetti, Luigi
    Durante gli anni settanta e i primi anni ottanta numerosi contributi hanno analizzato le conseguenze di uno stato conflittuale delle relazioni industriali sulle performances delle imprese nel sistema industriale italiano.

  10. Struttura produttiva e concentrazione industriale. Il settore manifatturiero italiano 1951-1981

    Fiorentini, Gianluca
    Una delle principali questioni aperte nell'esaminare lo sviluppo economico italiano del dopoguerra è quella di spiegare la ragione per cui la struttura industriale italiana è stata ed è tuttora caratterizzata da una dimensione media di impianti e da un livello di concentrazione relativamente assai inferiore rispetto a quello degli altri paesi occidentali.

  11. Esternalita' di rete, sussidi pigouviani e mutmento tecnico

    Fiorentini, Gianluca
    Molti sono i beni la cui utilità per i consumatori non dipende dalle loro caratteristiche intrinseche, ma piuttosto dall'assistenza di un numero elevato di acquisizioni dello stesso prodotto da parte di altri consumatori.

  12. The Prevision of Public Inputs in Oligopolitic Markets

    Fiorentini, Gianluca
    Optimal rules for the provision of collective factor of production have been quite extensively investigated since the seminal cotributions of Kaizuka (1965) and Sandro (1972), that may be regarded as the counterpart of the Samuelson's papers on the optimal allocation of public goods amoung consumers.

  13. Ricardian Equivalence and Non Equivalence: An Overview

    Toso, Stefano
    This paper surveys some of recent theoretical developments in the Ricardian equivalence debate.

  14. Cost Reducing Inputs, Underproduction and Economic Welfare

    Fiorentini, Gianluca
    The object of this paper is to investigate social and strategic overinvestment in cost reducing inputs, when such investment enters directly in the other firms' objective function.

  15. Public Inputs as Signalling Devices

    Fiorentini, Gianluca
    A two stage model is built where the first period strategic variable is used to update the information available on some private characteristics of the rival firms.

  16. Asymmetric Information in Public Provision Mechanisms

    Fiorentini, Gianluca
    An optimal mechanism fot the provision of impure public inputs to oligopolistic firms is investigated using a three stage game where in the first stage the public agency which provides the public input fixes a non-linear price schedule.

  17. Strategie di finanziamento delle imprese, decisioni di risparmio e ruolo del istema tributario

    Giannini, Silvia
    Negli anni più recenti si è assistito, in tutti i paesi industrializzati, ad un rinnovato interesse per le politiche pubbliche indirizzate ad incentivare l'accumulazione di capitale da parte delle imprese.

  18. Legge finanziaria 1986: le "Disposizioni in materia socio sanitaria"

    Giannini, Silvia
    La legge finanziaria per il 1986 interviene estesamente in materia di finanziamento del Servizio sanitario nazionale (gli articoli sono 5, suddivisi in 32 commi, nel testo approvato dal parlamento ed erano 8, suddivisi in 43 commi, nel testo presentato al Governo).

  19. Economic and Political Equilibria in Optimal Taxation. Is Incentive Compatibility Enough?

    Fiorentini, Gianluca
    This paper is an attempt to describe the discal structure of State as an equilibrium of a non-cooperative game where decentralized agents play both political and economic strategies. We propose a theory of fiscal equilibria (describing features of direct and indirect taxation as well as of the expenditure side of the public intervention) arising from the voluntary interaction among decentralized and fully size of the public sector. Among the main results we show that: (i) the greater is the size of the public sector, the more income taxation prevails on expenditure taxation; (ii) the beter is the monitoring technology on...

  20. The Italian School of Public Finance at the Turn of the Twentieth Century and the Ricardian Equivalence Theorem

    Toso, Stefano
    In this paper we re-examine the contribution of the Italian tradition of public finance to the issue of differential incidence of tax and debt financing. The protracted controversy, now restated as whether government bonds are considered as net wealth, goes back to Ricardo's proposition that the method of financing any particular level of government expenditure is irrelevant. As a matter of fact, it is only at the turn of this century that we get a critical evaluation of that proposition and its assumptions, which remained implicit in Ricardo's work. This was accomplished by the Italian school of public finance. That...
