The aim of this paper is to study whether politicians manipulate fiscal policy to extract private rents. We focus on the local personal income tax (PIT), in the setting of Italian cities, which is a progressive instrument that allows mayors to set different rates to distinct wage groups. We exploit discontinuities in mayors’ salaries, that are based on population thresholds, to study whether mayors systematically apply lower rates to their own tax bracket. The main results document large rent-seeking activity in fiscal policy. First, we show that when mayors’s salary is exogenously located in the following tax bracket this receives a significantly lower tax rate than the previous bracket, compared to the control group. Second, we show that this rent-seeking activity is highly detrimental for the public treasury, with a considerable reduction in fiscal revenues. And finally, we document that the monetary gains for rent-seeker politicians are rather limited. These results suggest that when fiscal policy is prone to be manipulated politicians do not hesitate to engage in rent-seeking activities even in case of little profits.

This paper aims to investigate whether friends’ and peers’ behavior influence and individual’s entry into marriage and parenthood during the transition to adulthood of young, U.S. adults. After first studying entry into marriage and parenthood as two independent events, we then examine them as interrelated processes, thereby considering them as two joint outcomes of an individual’s unique, underlying family-formation strategy. Using the National Longitudinal Study of Adolescent Health, we engage in a series of discrete time event history models to test whether the larger the number of friends and peers who get married (or have a child), the sooner the individual gets married (or has a child). Results show strong cross-friend effects on entry into parenthood, whereas entry into marriage is only affected by peer effects. Estimates of a multiprocess model show that cross-friend effects on entry into parenthood remain strongly significant even when we control for cross-process unobserved heterogeneity.

OBJECTIVE: In this study we test whether perceived stability of employment and perceived resilience to potential job loss affect fertility intentions, net of individual level risk attitudes and considering variation in the local macroeconomic conditions. BACKGROUND: The role of employment uncertainty as a fertility driver has been explored in a number of studies with a limited set of constructs, and with inconclusive results. A key reason for this heterogeneous pattern is that scholars did not recognize the multidimensionality and the prospective nature of employment uncertainty. We address these oversights by considering two key dimensions of employment uncertainty: perceived stability of employment and perceived resilience to potential job loss. METHOD: Our study is conducted using the newly-released 2017 OECD Italian Trustlab survey and its built-in module on self-assessed employment uncertainty (N=521). We perform multivariate analysis using ordered logistic regression. RESULTS: Perception of employment resilience was a powerful predictor of fertility intentions, whereas perception of employment stability had only a limited impact. The observed relationship between resilience and fertility intentions was robust to the inclusion of person-specific risk attitude and it did not depend on aggregate-level variables, such as unemployment and fixed-term contract rates in the area of residence. CONCLUSION: With this paper, we argue that the notion of resilience is crucial for making sense of economic prospects in connection to fertility planning.

Recent developments in applications of network analysis to history are leading to a new way of thinking about how social and economic actors interacted in the past. Focus on the social tie has resulted in increased interest in relational instruments that have not previously been taken into great consideration. This article analyses some of these instruments, and particularly godparenthood and marriage witnessing, as ways to establish formal and public ties. It shows that formalisation, ritualisation and publicity of ties were used by entrepreneurs to establish trust with their business associates, in situations when information was asymmetric or when institutions were perceived as inefficient in guaranteeing mutual good behaviour. The paper underlines both factors of continuity and factors of change over time, from the Middle Ages to today, paying particular attention to the consequences of Reformation and Counter-Reformation on one hand, and of Industrial Revolution and Modernization on the other. It shows, in the light of the most recent literature, that much of what we think to know about the declining importance, for social and economic activity, of family ties and of weaker ties such as godparenthood, is actually a kind of prejudice originating from a twentieth-century ideology of the market in which ancient practices struggle to find a place but are not abandoned.

This paper aims to answer to what extent fertility has a causal effect on households economic wellbeing-an issue that has received considerable interest in development studies and policy analysis. However, only recently has the literature begun to give importance to adequate modelling for estimation of causal effects. We discuss several strategies for causal inference, stressing that their validity must be judged on the assumptions we can plausibly formulate in a given application, which in turn depends on the richness of available data. This discussion has a general importance, representing a set of guidelines that can be helpful to choose the appropriate strategy of analysis. We contrast methods relying on the Unconfoundedness Assumption, which include regressions and propensity score matching, with Instrumental Variable methods. We discuss why they give different estimates of the causal effect using data from the Vietnam Living Standard Measurement Survey.

ABSTRACT Using longitudinal data from the Generations and Gender Surveys (for Bulgaria, France, and Italy), we study the determinants of predicted happiness associated with childbearing and then its role for explaining realized childbearing. “Expected happiness”, as declared by individuals, is indeed a powerful predictor of their fertility behavior. Those who expect to be happier from childbearing indeed have a much higher probability of having a child within the following three years.  But the results also show strong gender and country differences in the level of expected happiness and its effect on fertility behavior. For example, in Italy we see that individuals tend to have a high expected happiness from childbearing, yet realized fertility is low. What separates this study from recent papers considering happiness and fertility is that in the GGS the question about happiness is specific with respect to childbearing. Previous studies tend to focus on overall happiness, which has the drawback of, first, having relatively low variation in responses, and second, it refers to the general level of happiness, which incorporates a whole range of factors, not just children.
