Can unbiased be tighter? Assessment of methods to reduce the bias-variance trade-off in WTP estimation

This paper aims at verifying the claim, appeared in recent literature, that it is possible to control for response bias associated to the double bound elicitation method, while keeping gains in efficiency of the WTP estimates. Results from a Monte Carlo analysis lead, in general, to reject the claim; but when initial bids are not correctly chosen, the gains in efficiency are confirmed. An empirical application dealing with WTP estimation for drinking water quality improvements illustrates a case where a flexible modeling approach based on Copula distributions allows relevant gains with respect to the Single Bound estimator.     

Sulla stima della media e del secondo momento di una popolazione tramite campioni con risposta casualizzata

Il campionamento con risposta casualizzata, introdotto da S. L. Warner per la stima di proporzioni ed in seguito applicato dallo stesso autore e da altri alla stima di quantità, è stato oggetto di un recente studio di D. Olivieri che, proposto un semplice metodo di casualizzazione, perviene ad una stima non distorta della media della popolazione oggetto d'indagine.Nel presente lavoro si sviluppa lo studio di Olivieri fornendo una stima non distorta del secondo momento della popolazione e si propone un'altra stima della media e della varianza della popolazione ottenuta tramite un metodo di casualizzazione di più semplice applicazione.

The randomized response technique of sampling was proposed for the first time by S. L. Warner for the estimation of proportions and then applied, by Warner himself and other authors, to the estimation of quantities.This technique has been recently the object of an approach by D. Olivieri who suggests an easy randomization method and obtains an unbiased estimate of the population mean.In this paper the approach of D. Olivieri is implemented, reaching an unbiased estimate of the second moment of the population; moreover, an other estimate of the mean and of the variance of the population, obtained by an easier-to apply method of randomization, is proposed.

How brand innovativeness creates advertising flexibility

We advance a broadened conceptualization of advertising context effects by considering how consumer response is influenced by the competitive advertising context. This contextual variable reflects how typically or atypically advertising tactics are employed by brands in a product category. Study 1 demonstrates that employing an advertising tactic that is perceived by consumers as atypical in a category undermines its influence on brand attitudes. Study 2 shows that this persuasion penalty is circumvented by innovative brands through a phenomenon we refer to as advertising flexibility that enables innovative brands to successfully employ advertising tactics under a wider range of conditions than non-innovative brands. A final study provides process evidence for this effect by showing that brand attitudes are determined by advertising content for innovative brands but by considerations of the competitive advertising context for non-innovative brands.     

Assessment of storm surge damage to coastal settlements in Southeast Florida

Coastal cities are growing at a very rapid pace, in terms of both population and physical assets, and great uncertainty surrounds the future evolution of hurricane intensity and sea-level rise. The combination of these trends will contribute to large financial losses due to property damage in the absence of specific protections. Southeast Florida represents a clear hot spot of coastal flood exposure: more than 5?million inhabitants live in the counties of Miami Dade, Broward, and Palm Beach, and the population is still growing. It is also a low-lying area where tropical hurricanes hit frequently. This article illustrates a methodology to assess coastal flood damage in urban settlements and it aims to determine more general lessons useful for all coastal cities. We consider the impact of different storm surges predicted by the SLOSH model and investigate flood risk considering different types of hurricanes. For each event, we apply a specific damage function and determine whether the considered storm surges potentially lead to an asset loss, considering both properties and their contents. The results show that, in the absence of protections, losses will be very high for large storm surges, reaching up to tens of billions of US dollars. In the second part of the analysis, we demonstrate how economic impact changes when protections are built up, considering different heights of protections. These results could be used as inputs into a robust decision-making process to determine the future of coastal protection in southern Florida.     

Consumption and income smoothing

This article presents a two-sector dynamic general equilibrium model in which income smoothing takes place within the households (intra-temporally), and consumption smoothing takes place among the households (inter-temporally). Idiosyncratic risk-sharing within the family is based on an income smoothing contract. There are two-sectors in the model, the regular sector and the underground sector, and the smoothing comes from the underground sector, which is countercyclical with respect to aggregate GDP. The article shows that the simulated disaggregated consumption and income series (that are the regular and underground consumption flows) are more sensitive to exogenous changes in sector-specific productivity and tax rates than regular and underground income flows, and that this picture is reversed when the aggregate series are considered.     

Tax avoidance in government-owned firms: Evidence from Italy

This paper studies whether and why government-owned firms avoid taxation to a greater extent than wholly privately-owned firms do. By considering a sample of Italian listed corporations for the period between 2006 and 2011, it was found that government ownership had a systematically negative effect on corporate effective tax rate, with a prevalence of tax-planning policies focused on the long term. Managers of local government-owned firms focused on minimizing costs, even if this was to the detriment of national tax-revenue collection.     

Comparing the impact of management on public and private sector nurses in the UK,Italy, and Australia

The research examined the impact of management upon employee outcomes (perceptions of discretionary power, well-being, engagement, and affective commitment), comparing public and private sector nurses in Australia, the United Kingdom, and Italy. Overall, 1,945 nurses participated in a self-report survey within these core- and laggard-New Public Management countries. While management influenced employee outcomes for each country, there were significant differences between the public and private sectors, with private sector nurses reporting higher perceptions of outcomes. Importantly, nurses’ engagement was affected by management practice for each country. This study raises important implications for nurse managers, especially public sector managers, described within.     

The influence of positive affect on consideration set formation in memory-based choice

Although prior research has examined whether positive affect can impact consideration set size in stimulus-based choice, unknown to this point is whether affective influences also characterize memory-based consideration processes. This distinction is important insofar as consideration in memory-based choice entails psychological processes (including those involving the accessibility of brands) that are unique to choice undertaken in memory-based settings. Experiment 1 provides an initial demonstration of positive affect’s ability to shape memory-based consideration by documenting that positive (versus neutral) affect leads to larger consideration sets. Two additional experiments extend these findings by showing that the influence of positive affect on consideration set size is moderated by characteristics of brands (typicality) and consumers (regulatory focus). Experiment 2 demonstrates that this increase in memory-based consideration set size is attributable to a greater number of atypical, but not typical, brands being considered under positive affect. Experiment 3 documents the moderating effect exerted by consumers’ regulatory focus by showing that the ability of positive affect to increase consideration set size is more likely for consumers high (but not low) on promotion focus. The theoretical and managerial implications of these findings are discussed as are suggestions for future research.     

Austerity and repressive politics: Italian economists in the early years of the fascist government

The historical forerunners of contemporary austerity are still largely unexplored. This essay considers the “liberal phase” of Fascist Italy (1922–1925) as a case study to explain austerity as a full-blown rationality, that is intrinsically, and simultaneously, theory and practice, encompassing the moral, the economic and the political. My explanation moves beyond the interpretation of austerity as the post-1980, neoliberal recipe of price deflation and budget cuts. The Italian case draws attention to a neglected connection: that between austerity and repression. Austerity was the guiding principle of the Fascist economic agenda during the 1920s. It served to extinguish the effects of the democratisation process of the post-WWI years. The paper examines the work of four distinguished economists, Maffeo Pantaleoni, Luigi Einaudi, Alberto De Stefani and Umberto Ricci, who – in different roles as professors, journalists, advisors, and policy-makers – can be considered the source, the guardians and the enforcers of Fascist austerity.     

Does Branch Religiosity Influence Bank Risk‐Taking?

Using branch‐level data on public and private US banking institutions, we investigate the importance of branch religiosity in shaping bank risk‐taking behavior. Our results show robust evidence that branch religiosity is negatively related to bank risk‐taking. This effect persists after controlling for several bank‐level and county‐level variables that might correlate with religiosity. Moreover, this result is robust to controlling for headquarter religiosity, suggesting that the effect of branch religiosity is additive and not washed out by headquarter religiosity. Overall, our findings document that headquarter religiosity does not capture the full effect of religiosity on bank behavior, as claimed by previous research, but that the religiosity of the geographic area in which the bank operates significantly influences bank behavior.
