Family dissolution and precautionary savings: an empirical analysis

The main research question of this paper is whether or not the risk of family disruption has an impact on the consumption/saving decisions of households. Although little empirical work exists in this area, often presenting indirect evidence, the theory is divided over the effect of family risk over saving and wealth accumulation. By using data from the Italian Survey on Households Income and Wealth, we build a probabilistic model to assess the probability of marital splitting, and then we insert this probability as a distinct or interacted regressor, in a statistically consistent way, into a linear model of consumption. Furthermore, we study the differential behaviour, in terms of consumption/saving choices, of couples experiencing marital splitting over the subsequent 2?years. The main result of our analysis is that family disruption risk generates precautionary savings, reducing current consumption. In fact, according to our estimates, on average, the risk of divorce generates an amount of additional yearly precautionary savings of around 800 euros at constant prices of the year 2000, which represents 11% of overall household savings.     

MANAGING CREDIT BUBBLES

We study a dynamic economy where credit is limited by insufficient collateral and, as a result, investment and output are too low. In this environment, changes in investor sentiment or market expectations can give rise to credit bubbles, that is, expansions in credit that are backed not by expectations of future profits (i.e., fundamental collateral), but instead by expectations of future credit (i.e., bubbly collateral). Credit bubbles raise the availability of credit for entrepreneurs: this is the crowding‐in effect. However, entrepreneurs must also use some of this credit to cancel past credit: this is the crowding‐out effect. There is an “optimal” bubble size that trades off these two effects and maximizes long‐run output and consumption. The equilibrium bubble size depends on investor sentiment, however, and it typically does not coincide with the “optimal” bubble size. This provides a new rationale for macroprudential policy. A credit management agency (CMA) can replicate the “optimal” bubble by taxing credit when the equilibrium bubble is too high and subsidizing credit when the equilibrium bubble is too low. This leaning‐against‐the‐wind policy maximizes output and consumption. Moreover, the same conditions that make this policy desirable guarantee that a CMA has the resources to implement it.     

Environmental taxation and the double dividend hypothesis in CGE modelling literature: A critical review

Computable general equilibrium (CGE) modelling is a flexible and open way to model the economic systems that allow practitioners to assess the impacts of different policies or external shocks over an economic system. There is some empirical literature dedicated to test the double dividend hypothesis of an environmental tax reform using CGE models. This hypothesis claims that is possible to obtain an improvement of both environmental and economic conditions by imposing an environmental tax and recycling revenues obtained to reduce other pre-existing taxes. This research provides a comprehensive review of this literature including a statistical and a meta-regression analysis. 69 different simulations from 40 studies have been analyzed. 55% of simulations have achieved a double dividend, concluding that although the environmental dividend is almost always achieved, the economic dividend still remains an ambiguous question that needs further research.
