Enhancing the role of flow experience in social media usage and its impact on shopping

Online retailers are eager to find the answers to the following questions: How relevant is SNS usage to consumer shopping decisions? Is the information shared on SNS likely to influence users’ shopping decisions? This study is designed to answer these questions via essential factors based on flow theory and TAM. The moderating effects of some social factors were also explored. The data was collected from U.S SNS users, and SEM was performed and a research model estimated. The findings reveal that flow experience of SNS usage for shopping, perceived ease of use of SNS, and perceived usefulness of information shared on SNS exert positive and significant effects on consumer intention to shop on SNS. Particularly, flow experience directly and positively determines shopping intention and shares positive and significant impacts with TAM. Furthermore, the perceived usefulness is highly important relative to the perceived ease of use. Social identity, group norm, and social influence also positively moderate the links between flow experience, TAM, and SNS usage intention for shopping. Very few theoretical studies have discussed SNS usage behavior for shopping based on flow theory or validated its relationship with TAM in the SNS shopping context. A validated model of consumers’ actual usage of SNS for shopping proves that experience drives the success of social commerce. The findings provide current information and important aspects to firms that operate SNS commerce, allowing them to adjust their marketing strategies to serve consumers better.

The effect of female representation on political budget cycle and public expenditure: Evidence from Italian municipalities

This study analyzes the impact of the gender composition of political institutions on the political budget cycle (PBC) and on the size and structure of public expenditure. An instrumental variable approach is implemented to evaluate the influence of female politicians in municipal councils. The introduction of gender quotas for Italian municipalities is used as an exogenous variation in female participation in politics. The results show that: (i) fluctuations in local public spending are only slightly affected by the presence of a wider female representation; (ii) an increase in the number of elected women reduces the overall amount of public expenditure; (iii) this reduction involves fields typically affected by PBC (e.g., roads' maintenance) except those related to females' needs (e.g., kindergarten, primary education, and social care).     

A reservation-based parking behavioral model for parking demand management in urban areas

The rapid increase in car ownership has become a land-use problem in many cities which have limited land for parking. It also has adverse impacts on congestion, air quality, energy consumption, as well as losses in productivity, among other consequences. The problem worsens in some cities due to the adoption of inefficient mandatory minimum parking policies for new projects, according to a building's use and size, which incentivizes driving. Therefore, it is necessary to assess appropriate parking management policies that maximize social welfare. In this regard, this paper presents a reservation-based parking behavioral hybrid choice model for parking demand management policies in urban areas, that appropriately represents the behavior of private vehicle users when choosing their parking site. The proposed model is statistically significant and consistent with expected behavior and microeconomic theory. The results demonstrate that the possibility of reserving a parking space has a significant impact on car parking market share on- and off-street. The three latent variables included in the model (pro-parking attitude, perception of risk for parking on- and off-street) have a significant effect on the modal split and the evaluation of appropriate parking policies that consider heterogeneity. The latent variable that most impacts the modal shift is the pro-parking attitude, which can generate up to 7% change in the modal partition.     

The financial and green effects of cultural values on mission drifts in European social enterprises

The sustainable social enterprises (SEs) literature shows that SEs have to simultaneously pursue economic, social, and environmental aims. However, tensions between these objectives can make this a challenging task and lead towards mission drift. This work investigates if the cultural dimension can forecast the mission drift. We empirically analyze this relationship in three stages. In the first stage, we identify a homogeneous dataset of 287 sustainable SEs from seven EU countries from 2011 to 2020. Then, in the second stage, we apply the data envelopment analysis (DEA) methodology to calculate the efficiency of the SEs. An efficient SE has to simultaneously achieve social, environmental, and economic aims. We calculate a proxy of the mission drift and generate a dichotomous category variable that assigns value 1 to the SE not affected by mission drift, 0 otherwise. In the last stage, we implement the 2SLS logistic regression between the variable that identifies the SEs affected by mission drift and three cultural dimensions: avoidance of uncertainty, masculinity, and short-term orientation.     

The effects of inter-municipal cooperation and central grant allocation on the size of the French local public sector

The analysis of French municipalities’ public personnel expenditures allows us to study the issue of the size of the local public sector. We concentrate on two paths that French authorities have followed to limit it, i.e., the promotion of inter-municipal cooperation (IMC) and the cut in grants received by municipalities. Our objective is to evaluate their respective role in the evolution of public personnel expenditures at the municipal level, in a context where local politics comes into play. We consider a large panel dataset of municipalities embedded in IMC structures between 2011 and 2018. Our main results, obtained using an original identification strategy, are threefold. We first find evidence that a substitution effect between municipal and IMC personnel expenditures is at work. Second, we find a partisan distorsion through the grant allocation: despite its formula-based definition, aligned and unaligned municipalities are treated differently by the central government. Third, we show that cuts in grants lead to cuts in municipalities’ public wage bills, while partisanship hinders such cuts.     

Physical activity,leisure-time,cognition and academic grades: Connections and causal effects in Chinese students

Academic achievement and positive leisure activities are traditionally considered significant determinants of economic growth and human capital accumulation. This paper estimates the impact of physical activity on academic outcome and time allocation to 25 different types of leisure activity by Chinese adolescents. We use structural equation models (SEM) to explore the channels of this transmission. Our results suggest that physical exercise not only exerts a positive direct effect on academic outcome but also increases (decreases) students' time devoted to activities that are positively (negatively) correlated with academic outcome. All the effects are statistically significant but modest at the individual level. Our findings are robust to different exercise frequencies and academic outcome indicators based on students' self-assessment, academic scores, and cognitive tests.     

Universities’ efficiency and the socioeconomic characteristics of their environment — Evidence from an empirical analysis

This paper investigates how the efficiency of universities is affected by the characteristics of the territory in which they operate. The theoretical framework combines two perspectives: (1) the resource dependence theory, suggesting that the location of university can determine the amount of resources available to it; (2) institutional isomorphism, according to which the characteristics of other higher education institutions located in the same area may shape the university production function and the efficiency of its operations. In order to test this framework we use data on Russian universities and a non-parametric conditional order-m efficiency estimator with two categories of contextual variables. The first group includes the social, economic and cultural characteristics of the region where the university is located, while the second deal with the characteristics of other higher education institutions located in the same region. The main contribution of this paper is that it applies efficiency models that incorporate exogenous factors associated with a geographical area in context of higher education. Our findings highlight that the managerial efficiency of universities is strongly associated with the contextual factors of the environment in which they are embedded. Important policy implication of this result is that different public policies in higher education should treat particular universities differently depending on characteristics of context in which they operate.     

Italy: Immigration and the evolution of populism

We study the effect of immigration on the upsurge of right-wing populism in Italy. Our data considers electoral results at the municipality level of the Senate of the Italian Republic and the Chamber of Deputies over the period 2006–2018. Using an IV strategy based on the shift–share instrument, we find that immigration generates a sizable causal increase in votes for the right-wing populist party Lega. Immigration also works as a major catalyst for the electoral distance between Lega and its most direct competitors. We explore how different levels of tax autonomy impact the results, as well as how the re-branding of Lega as a national movement affects the relation between immigration and support for the party.
