Team reasoning theory: an experimental analysis of common reason to believe and social distance

The aim of this paper is to study the role of the “common reason to believe” (Sugden in Philos Explor 16:165–181, 2003) and the reduction of social distance within the theory of team reasoning. The analysis draws on data collected through a Traveler’s Dilemma experiment. To study the role of the common reason to believe, players’ beliefs in their counterparts’ choices are elicited, and the correlation between the endorsement of team reasoning and beliefs is considered. The relation between social distance and team reasoning is analyzed by introducing a meeting between the two players after the game. We show that the common reason to believe appropriately explains the internal logic of team reasoning and that a reduction of social distance does not produce any statistically significant effect on the probability that team reasoning will be used.     

Determinants of adaptation costs in procurement: an empirical estimation on Italian public works contracts

It is widely agreed that rules governing public procurement should be designed to achieve value for money. However, in the public works sector, ‘…?the good being procured is usually complex and hard to be exactly specified ex ante, …?[and] alterations to the original project might be needed after the contract is awarded. This may result in considerable discrepancies between the lowest winning bid and the actual costs that are incurred by the buyer’ (Bajari et al., 2006). There is now a wide body of literature focusing on cost escalation during the execution of contracts and their estimates reveal that it can be often quite large. This article is aimed at offering an empirical test of the determinants of adaptation costs in the public works procurement. Using a detailed data set on Italian public works contracts, we run an empirical analysis, grounded on the main conclusions reached in the literature, to test for the main drivers of adaptation costs.     

Manual and Automated Procedures for Compiling a Very Large Sample of Centenarian Pedigrees

A large portion of the baby boomer population will live beyond the age of 90 years, and entitlement programs and various insurance products have thus become interested in longevity risk. Beyond cohort life table predictions, actuaries have little to go on in determining which individuals or portions of populations are at increased risk of living to 90 or 100 or even older. We and others have noted strong familial risk for living beyond the oldest one percentile of survival, and we developed an algorithm that uses information about relatives’ longevity to compute the chance of an individual surviving to extreme old age. An important step of this work is to compile large samples of pedigrees with and without long-lived family members. Here we describe our process of hand curation of centenarian pedigrees and software that we have developed for the automated construction of such pedigrees using internet-based resources that can support the manual process.     

Sequential contracting with multiple principals

This paper considers dynamic games in which multiple principals contract sequentially and non-cooperatively with the same agent. We first show that when contracting is private, i.e. when downstream principals do not observe the mechanisms offered upstream and the decisions taken in these mechanisms, all PBE outcomes can be characterized through pure-strategy profiles in which the principals offer menus of contracts and delegate to the agent the choice of the contractual terms. We then show that, in most cases of interest for applications, the characterization of the equilibrium outcomes is further facilitated by the fact that the principals can be restricted to offer incentive-compatible extended direct mechanisms in which the agent reports the endogenous payoff-relevant decisions contracted upstream in addition to his exogenous private information. Finally we show how the aforementioned results must be adjusted to accommodate alternative assumptions about the observability of upstream histories and/or the timing of contracting examined in the literature.     

On the anti-competitive effects of quantity discounts

We analyze the competitive effects of quantity discounts in an asymmetric duopoly. We find that for a sizeable set of parameter values, quantity discounts harm the smaller firm and reduce consumers' surplus. They can even decrease social welfare, i.e. the sum of producers' and consumers' surpluses. However, the circumstances in which quantity discounts may decrease social welfare are limited and difficult to identify in practice.     

The New Deal for Young People Five Years On*

The New Deal for Young People is the major welfare‐to‐work programme in the UK. It is a mandatory multistage policy targeted at 18‐ to 24‐year‐old unemployed people. This paper investigates the long‐term effectiveness of the programme in terms of enhancing the (re‐)employment probability of participating men. It exploits the eligibility rule to identify a suitable counterfactual relying upon a simple regression discontinuity design. The combination of job‐search assistance, training, wage subsidies and job experience enhances employability by about 4.6 per cent and this effect lasts over different cohorts.     

On the conceptualization and measurement of dynamic capabilities for sustainability: Building theory through a systematic literature review

We performed a systematic literature review to explore and understand how the 23-year long debate about dynamic capabilities has addressed sustainability issues. Based on this, we propose a unifying framework that distinguishes different facets of dynamic capabilities for sustainability (DCsS) based on the different types of performance they are more suitable to predict. The theoretical contribution is twofold. First, we add to the literature by highlighting the dependence of different forms of DCsS on different levels of the centrality of sustainability outcomes in corporate strategies. Second, we shed light on the operationalizations of DCsS by providing guidance on the adoption of pertinent constructs and measurement models. The review concludes with a discussion of the managerial implications of the proposed conceptual framework to help decision makers better understand, which strategic moves to make to achieve their intended sustainability goals.     

“Couchsurfing has made me a better person and the world a better place”: the transformative power of collaborative tourism experiences

ABSTRACT

Presented as an alternative form of tourism, Couchsurfing is a predominantly non-commercial accommodation type where hosts offer a “couch” to travelers through a hospitality network. Couchsurfing.com is considered as an icon of the sharing economy and more specifically of shareable tourism. This article provides a deeper understanding of couchsurfers’ motivations and shared values. Through an empirical qualitative study, we discuss the transformative power of Couchsurfing experiences, the underlying transformational processes, conditions, and socio-psychological and behavioral consequences. We also discuss the findings’ implications for society, businesses, and tourism in general.
