Dynamic Tax Evasion with Habit Formation in Consumption*

We model the optimal intertemporal decision of an agent who chooses tax evasion and consumption, over an infinite lifetime horizon, where consumption is driven by habits. We find the following: (i) tax evaders reduce consumption in the early stages of habit accumulation and increase it over time; (ii) habit formation has a dampening effect on tax evasion; (iii) neglecting tax evasion can lead to habit overestimation; (iv) the effect of the tax rate on tax evasion is ambiguous; (v) heavy fines are more efficient than frequent controls in reducing tax evasion.

REGULATION STRATEGIES FOR THE PROVISION OF PATERNALISTIC GOODS

In this study, we analyze the regulation of markets for the provision of services whose costs are subsidized for paternalistic reasons. We model the choice of a benevolent regulator who wants to maximize consumer welfare in a setting where quality cannot be verified and the good provided is fully subsidized. The choice is thus made between two types of providers (profit maximizers and altruistic providers) and two frameworks (monopoly franchise and quality competition). Our analysis shows that in this environment the performance of mixed markets is always dominated by pure forms. Moreover, although making efficient providers compete for the market minimizes cost, the choice of quality competition with altruistic providers may be preferable from a welfare point of view whenever service quality is relevant and the productivity differential is not substantial.     

Gender and culture: do they matter for norms?

In a natural experiment, we observed that the influence of a norm depended upon the gender and cultural background of participants. Both gender and cultural background contributed to the effect of peer pressure that partly controlled against the act of cheating among participants as they completed a group task. Furthermore, both factors served to describe the characteristics of hardworking individuals in the group. We therefore conclude that the effectiveness of a norm in a group is expected to depend upon the presence of hardworking individuals therein.     

Flypaper Effect and Sluggishness: Evidence from Regional Health Expenditure in Italy

In Italy, public expenditure reduction is achieved through a revision of social security and health care programs. In particular, public health expenditure control has been implemented through a reform that imposes more stringent budget rules to local governments and a considerable reduction in grants-in-aid from the central government. This paper investigates empirically whether the response to this decrease in categorical lump-sum grants from the central to local governments results in an asymmetric response to intergovernmental grants. Hard budget and soft budget constraint hypotheses are estimated by using a sample of cross-sectional and time observations covering the 20 Italian regions over the period 1989–1993. The main finding is the existence of a standard and a super flypaper effect in both models. The introduction of the soft-budget constraint hypothesis results in a stronger effect of grants and a lower response of own resources which shows that local governments prefer to incur some deficit instead of reducing health care expenditure.     

Crowdfunding for the development of smart cities

In recent years, many cities have experienced new forms of collaboration that have an impact on citizens and entrepreneurs. The integration of this field of study with civic crowdfunding can influence economic growth and community building, which may be beneficial for both policymakers and practitioners alike. Civic crowdfunding is a financial model through which citizens, in collaboration with government and local authorities, fund projects to provide a community service. The development of smart cities is related to civic engagement, empowerment, and participation intended to be part of crowdsourcing or entrepreneurial activities. In this sense, cities play a vital role as drivers of (open) innovation and entrepreneurship. Based on these considerations, this study proposes an explorative and qualitative approach to investigate the civic crowdfunding phenomenon and its ability to promote community development. Our exploratory analysis of six projects highlights the challenges and opportunities of civic crowdfunding for the creation, development, and improvement of more inclusive cities.     

The optimal bid/ask spread in a Specialist System

In this work we propose a simple market model where some features of the Specialist System are analyzed. In particular, the specialist's obligation to display bid/ask quotes on the book within the bounds imposed by the Exchange is considered. The proposed model allows to analyze the effects of the specialist's interventions on the short term dynamics of bid/ask prices and address a relevant market design issue, that is determination and analysis of the optimal endogenous upper bound that - according to economic conditions - should be imposed by Stock Exchange on the quoted bid/ask spread. The institutional details are summarized in a few structural parameters and the focus is on the aggregate effects of excess demand/supply.     

EXIT, CHOICE OR LOYALTY: PATIENT DRIVEN COMPETITION IN PRIMARY CARE

ABSTRACT ** :  This paper analyses the potential costs and benefits from patient driven competition between GPs and specialists by comparing gate-keeping with direct access to specialist care. The two access rules are compared under fee-for-service and capitation, on their performance at minimizing both total financial costs and patients' opportunity cost of time in care. To analyse the social cost of patients' potential access mistakes, two types of illnesses are considered, with two levels of severity and an equal probability for each of the four events. The results generated under information symmetry show that gate-keeping always dominates in terms of minimizing financial cost. Results are extended to show that under patients' heterogeneity with respect to time preferences, allocative efficiency can be enhanced in gate-keeping by giving the patient the option to seek a specialist directly, provided he bears the extra cost. When turning to information asymmetry, results are reversed, and direct access is shown to be more cost effective. This is due to patients' ability to constrain providers' opportunistic behaviour by 'voting with their feet'. Beyond increasing allocative efficiency, patient choice is therefore found, under certain conditions, to contribute towards enhancing productive efficiency. Finally, introducing co-payments to share the financial risk associated with direct access potentially weakens patients' ability to curb providers' strategic behaviour. Under information asymmetry, direct access to specialist care should therefore remain free if patient's disutility in time in care is linear. When it is instead increasing, we show that a co-payment becomes necessary to curb specialists' information rent. Finally, under information asymmetry, the mixed solution (gate-keeping with optional direct access) improves on pure gate-keeping but is still suboptimal.     

Would less regional income distribution justify the present call for devolution?

We model a local public good with spillovers, in a framework where devolution is socially inefficient. Nevertheless, we show that decentralisation may be preferred by one region if it implies a reduction in regional income redistribution. This result is due to the inter-regional mechanism of the equalisation grant. For an expenditure-based grant, we define a threshold for regional income disparity above which decentralisation is preferred, while for a resource-based grant the threshold depends on the spillover and the difference in preferences for the local public good. Finally, for given levels of regional income disparity we show which grant form may minimise the claims for decentralisation.
