Seeds of distrust: conflict in Uganda

We study the effect of civil conflict on social capital, focusing on Uganda’s experience during the last decade. Using individual and county-level data, we document large causal effects on trust and ethnic identity of an exogenous outburst of ethnic conflicts in 2002–2005. We exploit two waves of survey data from Afrobarometer (Round 4 Afrobarometer Survey in Uganda, 2000, 2008), including information on socioeconomic characteristics at the individual level, and geo-referenced measures of fighting events from ACLED. Our identification strategy exploits variations in the both the spatial and ethnic intensity of fighting. We find that more intense fighting decreases generalized trust and increases ethnic identity. The effects are quantitatively large and robust to a number of control variables, alternative measures of violence, and different statistical techniques involving ethnic and spatial fixed effects and instrumental variables. Controlling for the intensity of violence during the conflict, we also document that post-conflict economic recovery is slower in ethnically fractionalized counties. Our findings are consistent with the existence of a self-reinforcing process between conflicts and ethnic cleavages.     

A POSITIVE THEORY OF GEOGRAPHIC MOBILITY AND SOCIAL INSURANCE*

This article presents a tractable dynamic general equilibrium model explaining cross‐country data on geographical mobility, unemployment, and labor market institutions. Rational forward‐looking agents vote on unemployment insurance (UI). Agents with higher moving costs (larger attachment to their location) prefer more generous UI. Attachment is assumed to increase with the duration of residence. UI mitigates incentives for moving and increases, therefore, the fraction of attached agents and the political support for UI. This self‐reinforcing mechanism can yield two steady‐states: one “European” and one “American.” The former (latter) features high (low) unemployment, low (high) geographical mobility, and high (low) UI.     

The mediating role of work engagement on the relationship between job involvement and affective commitment

This study examines job involvement and work engagement as predictors of affective commitment. Specifically, we test the proposal of Hallberg and Schaufeli (2006) that work engagement is a mediator of the relationship between job involvement and affective commitment using a survey of 405 Italian working adults. To test the model, mediation effects technique and structural equation modelling were applied to the collected data. Our hypothesis that work engagement fully mediates the relationship between job involvement and affective commitment was supported. This is the first study to demonstrate the importance of job involvement in promoting affective commitment via three dimensions of work engagement. We therefore assert that HR managers should direct their available resources to promoting job involvement and work engagement in their employees.     

Estimation of Residential Water Demand with Imperfect Price Perception

Using data from a household survey carried out in the French overseas territory of Réunion, we investigate the price of drinking-water perceived by households faced with an increasing, multi-step pricing scheme. To this purpose we use an improved version of the method introduced by Shin (Rev Econ Stat 67(4):591–598, 1985) to estimate the demand for residential water when consumers are imperfectly informed about their pricing schedule. The empirical results suggest that Réunion households underestimate the price of water and thus consume more than what is economically rational. Providing information to households about the marginal price of water may be an innovative means of inducing them to respond to pricing policies designed to promote water conservation.     

The Minimum Economic Dividend for Joining a Currency Union

A two‐country model is developed to show how the optimality of a currency union depends on whether it brings an economic dividend in terms of potential growth and the Balassa–Samuelson (BS) effect (the steady appreciation of the real exchange rate due to cross‐country differences in intersectoral productivity gaps). The model shows that such dividend needs to be larger, the higher the BS effect, the smaller the size of the economy, the larger the cross‐country difference in the standard deviation of the supply shocks, the smaller their correlation and the larger the standard deviation of real exchange rate shocks. We calibrate the model to quantify such dividend as a function of plausible ranges of the parameter values. The results suggest that both the BS effect and the size of real exchange rate shocks play a key role in evaluating the optimality of accessing the currency union.     

Revisiting the Effects of Remittances on Bank Credit: A Macro Perspective

We investigate the effect of remittances on bank credit in developing countries. Understanding this link is important in view of the growing relevance of remittances as a source of external finance and of the beneficial impact that financial intermediation is likely to have on economic growth. Our contribution is twofold. First, we present a theoretical model of bank credit in a hypothetical remittances‐receiving country where: (1) the banking sector is imperfectly competitive; and (2) bank rates change infrequently because of the presence of adjustment costs. We show that in equilibrium, the relationship between remittances and bank‐credit is likely to be non‐linear. Second, we look at the evidence using a panel data set for a large group of developing and emerging economies over the period 1970–2009. We find that at initially low levels of remittances, an increase in remittances reduces the volume of credit extended by banks. However, at sufficiently high levels of remittances, the effect becomes positive. The turning point of the relationship occurs at a level of remittances of about 2.5% of GDP, which would imply that approximately 50% of our sample lies to each side of this threshold.     

Which are the determinants of green purchase behaviour? A study of Italian consumers

Green purchase behaviour is receiving a growing attention in the academic community, as understanding it is crucial for the growing number of companies developing and marketing green products. In order to provide a broader and novel picture of the phenomenon, this study extends the widely used Theory of Planned Behaviour (TPB) model in several ways, through a large survey of Italian consumers. First, three dimensions of green purchase behaviour are considered, namely, the willingness to pay a premium price, the green purchase frequency and the green purchase satisfaction. Second, several antecedents are considered simultaneously. Third, new (consumer creativity) or so far marginally studied (materialism and green practices) antecedents are included. Fourth, the mediating roles of green purchase satisfaction and willingness to pay a premium price in the link between the considered antecedents and the frequency of green purchase are investigated. Results show that the three dimensions of green purchase behaviour have different antecedents, so highlighting that green purchase behaviour is a multi-faceted phenomenon that should not be studied as a single general concept. Personal norms and value for money emerged to be very relevant predictors. The significant effects of creativity, materialism and green practices provide evidence that extending the TPB model with these three antecedents is useful to more deeply understand green purchase behaviour. Green purchase satisfaction is the strongest predictor of purchase frequency and mediates the effects of personal norms and value for money.
