A bivariate model for evaluating equity-linked policies with surrender option

This article proposes a bivariate lattice model for evaluating equity-linked policies embedding a surrender option when the underlying equity dynamics is described by a geometric Brownian motion with stochastic interest rate. The main advantage of the model stays in that the original processes for the reference fund and the interest rate are directly discretized by means of lattice approximations, without resorting to any additional transformation. Then, the arising lattices are combined in order to establish a bivariate tree where equity-linked policy premiums are computed by discounting the policy payoff over the lattice branches, and allowing early exercise at each premium payment date to model the surrender decision.     

Effects of fiscal policy in the Northern and Southern regions of Italy

This paper contributes to a growing body of work within ‘fiscal policy studies,’ investigating the recent role of fiscal policy on the Italian economy. Using annual data collected on a regional basis, this study estimates and compares the (impact and cumulative) fiscal multipliers across the North and the South—the less developed area—of Italy. With recourse to a simultaneous equation model for the two macro-areas of Italy, it estimates the overall impact of the measures of budget consolidation policies during the period 2011–2013. Our analysis reveals that tax increases and, with a greater impact, spending cuts, hit the South harder compared to the North.     

STATIC FUND SEPARATION OF LONG‐TERM INVESTMENTS

This paper proves a class of static fund separation theorems, valid for investors with a long horizon and constant relative risk aversion, and with stochastic investment opportunities. An optimal portfolio decomposes as a constant mix of a few preference‐free funds, which are common to all investors. The weight in each fund is a constant that may depend on an investor's risk aversion, but not on the state variable, which changes over time. Vice versa, the composition of each fund may depend on the state, but not on the risk aversion, since a fund appears in the portfolios of different investors. We prove these results for two classes of models with a single state variable, and several assets with constant correlations with the state. In the linear class, the state is an Ornstein–Uhlenbeck process, risk premia are affine in the state, while volatilities and the interest rate are constant. In the square root class, the state follows a square root diffusion, expected returns and the interest rate are affine in the state, while volatilities are linear in the square root of the state.     

EMU Stability: Direct and Indirect Risk Sharing

Our paper aims to analyze the effectiveness of different risk-sharing mechanisms in providing stability to a monetary union. We select two stylized tools with extreme and opposite features. The first is an expansionary but conventional monetary policy that is used to help EMU’s most fragile member states manage their public debts; the second is a centralized fiscal policy that allows for the transfer of a portion of these public debts from EMU’s most fragile member states to those considered EMU’s “core”. By a stylized periphery-core model of a monetary union, we compare the strengths and weaknesses of these two tools in order to reach some welfare implications in terms of union stability.     

The effectiveness of exchange-rate-based monetary policy: evidence from survey data

Singapore’s monetary policy is centred on the management of the exchange rate. We examine how macroeconomic forecasters perceive the effectiveness of this unconventional policy. We provide empirical evidence that forecasters’ expectations are consistent with a forward-looking exchange-rate-based Taylor-type policy rule. They expect monetary authorities to actively manage the currency against expected future changes in inflation and output.     

Networks and market-based measures of systemic risk: the European banking system in the aftermath of the financial crisis

This article investigates the behaviour of the European banking system during the financial crises that occurred in the last decades. Among the various approaches for measuring systemic risk, we consider network analysis, which describes the linkages among financial institutions and their whole structure. We construct a time-varying network of the European banking system. Banks are linked to form a global interconnected system and they mutually influence one another in terms of risk. We model their reciprocal influence via a weighted and directed network, in which weights are related to risk measures that are based on equity returns. Then, we apply two network indicators to investigate the prominence of a bank in spreading and receiving risk from the others. The results enable us to capture many features of the banking system while identifying the global systemically important banks. Moreover, the results of the analysis over time show how interconnections change over periods that are characterized by various economic scenarios.

     

When culture meets digital platforms: value creation and stakeholders’ alignment in big data use

Research on big data has highlighted that a crucial element to create value from data is the capability of aligning different stakeholders’ interests. However, it has not yet been investigated empirically how this process of alignment can be realized. We conduct a multiple case study on the two leading platforms involved in the online dissemination of cultural heritage – Europeana and Google Arts & Culture. Our findings reveal that a platform overtakes a rival one when it turns on multiple drivers of value creation in such a way that the drivers contribute to realigning the interests expressed by the stakeholders whose strategic objectives and beliefs were formerly divergent – or simply unrelated – to each other. This capability of realigning different stakeholders’ interests is independent of the level of industry-specific knowledge that the platform orchestrator has. The dynamics we document imply that Google has assumed a system integration role in the cultural ecosystem. This generates new trade-offs for museums in the way they generate value for the tourism industry. The paper enriches our understanding of what strategies digital platforms adopt to create value in big data contexts and provides a base to continue the investigation on other ecosystems driven by big data.     

Hippies,Greenies, and Tree Huggers: How the “Warmth” Stereotype Hinders the Adoption of Responsible Brands

Past research has highlighted the difficulty faced by responsible consumers, individuals who wish to make environmentally and socially responsible consumption choices. Individual buyers, it is argued, act within a network of structural and social relationships that make responsible alternatives intrinsically hard to pursue. This paper maintains that one such barrier is the perception that users of responsible brands are not worthy of social emulation. Consumers are less likely to adopt brands positioned explicitly on their positive environmental or social credentials because of the stereotypes attached to the users of these products. Two empirical studies demonstrate that users of responsible brands are perceived as stereotypically warm. Warmth, however, is not an appealing feature in a consumption context. Warm groups are not envied and envy plays a central role in fueling a desire to emulate a consumption group. The study is the first to examine the possibility that a group‐level stereotype limits the potential attractiveness of responsible brands. The significant implications of this insight for both scholarly research and marketing practice are examined in detail. The presence of a warmth stereotype, which has a negative influence on the social perception of responsible brands, suggests that the development of niches of responsible or ethical consumers is intrinsically problematic.     

Assessing social impact in the field of sustainable tourism development: Evidence from Cabo Delgado (MZ)

ABSTRACT

Assessing the social impact of tourism-related activities is of paramount importance to promoting sustainable development. The present study aimed to assess the social impact of a project in Cabo Delgado (MZ), designed to increase local community residents’ employability in the emerging tourism sector through the delivery of vocational training programmes, utilising a multi-phase and mixed-method design. The study comprised three different phases (before, during, and after the intervention) and took into account the perspective of a variety of stakeholders. Programmes were perceived to be effective by local operators in the tourism sector and trainees, as they enhanced their living conditions and increased their employability. International operators and tourists, however, had not yet perceived their effectiveness. This study offers a methodological framework for social impact assessment by performing a programme evaluation as an integral part of the intervention itself. This methodology can be extended to other non-tourism related contexts.     

Bowling alone, drinking together

This paper investigates to what extent youth alcohol consumption depends on consumption patterns by other household members and on social interactions outside the household. Exploiting the richness of the data, we explore the possibility of asymmetric social influences by gender and by age, the differences between use and abuse and among different types of alcohol consumption (beer, wine and spirits). Moreover, we control for contextual effects, such as variables related to neighbourhood and family background. We find that both the drinking intensity by other household members and a richer social life outside home are positively related to alcohol consumption. We also find that siblings are more influential than parents, that the mother is more influential for females and the father for males.
