Why Not in Your Backyard? On the Location and Size of a Public Facility

In this paper, we tackle the issue of locating a public facility which provides a public good in a closed and populated territory. This facility generates differentiated benefits to neighborhoods depending on their distance from it. In the case of a Nimby facility, the smaller is the distance, the lower is the individual benefit. The opposite is true in the case of an anti-Nimby facility. We first characterize the optimal location which would be chosen by a social planner. Then we introduce a common-agency lobbying game, where agents attempt to influence the location and provision decisions by the government. Some interesting results arise in the case where only a subset of neighborhoods lobby. First, the solution of the lobbying game can replicate the optimal solution. Second, under-provision and over-provision of the public good may be obtained both in the Nimby and the anti-Nimby cases. The provision outcome depends on the presence of either a congestion effect or an agglomeration effect. Third, some non-lobbying neighborhoods may be better off than in the case where all neighborhoods lobby, which raises the possibility of free-riding at the lobbying stage.

Special Interests and Technological Change

We study an OLG economy where productivity growth comes from two alternative sources: process innovation and learning-by-doing. There is a trade-off between the two in so far as frequent technological updates reduce the scope for learning on existing technologies. A conflict is shown to arise between the young and the old, because the former favor innovation while the latter prefer learning. We model the interaction between overlapping generations and policy makers as a dynamic common agency problem, where competing generations invest a certain amount of resources to lobby either for the maintenance of the current technology or the adoption of a new one. By focusing on truthful Markov perfect equilibria, we characterize the political equilibrium and show its dependence on the underlying demographic, technological and preference parameters.

Persistence of High Income Inequality and Banking Crises: 1980-2010

Differently from Atkinson and Morelli (2011) who detect no clear link between increases in income inequality and systemic banking crises, we show that a large majority of crises occurred between 1982 and 2008 have been preceded by persistently high levels of income inequality. Such association is robust when considering Gini values for incomes after-tax as well as before-tax and transfers. Moreover, we investigate the pattern of income inequality levels before and after a group of banking crises and the relative levels of income inequality in a large sample of OECD countries that did not experience banking crises between 1980 and 2010.

Aggregate uncertainty, political instability and income redistribution

Abstract This paper associates political instability with real shocks affecting the income of the median voter, in a two-period model where two political parties set redistribution in order to defend the interests of well-defined constituencies. Current policies affect future voting outcomes and an intertemporal trade-off arises for the parties since their optimal one-period strategy does not maximize the probability of being re-elected. The higher the volatility of the real shock, the more likely that parties deviate from the optimal one-period strategy by choosing a conservative strategy, which increases their chances of re-election and the expected lifetime utility of their constituencies.

Persistence of Politicians and Firms' Innovation

We empirically investigate whether the persistence of politicians in political institutions affects the innovation activity of firms. We use 12,000 firm-level observations from three waves of the Italian Observatory over Small and Medium Enterprises, and introduce a measure of political persistence defined as the average length of individual political careers in political institutions of Italian municipalities. Standard OLS shows no raw correlation between political persistence and firms’ innovation activity. However, once the causal effect is isolated by means of instrumental variables, using death of politicians as an exogenous source of variation of political persistence, we find a robust negative relation between political persistence and the probability of process innovation. This finding is consistent with the view that political stability may hinder firms’ incentive to innovate to maintain their competitiveness, as long as they can extract rents from long-term connections with politicians.

Compulsory Schooling Laws and the Cure Against Child Labor

Equally, poor countries display similar compulsory schooling laws but different levels of child labor and school attendance. This paper provides an explanation for the existence of child labor, which relies on the imperfect enforcement of compulsory schooling laws and is consistent with the above cross-country differences. In the presence of complementarities in the production of human capital that justify legislative intervention, mandatory measures ensure that coordination failures are solved so that all parents send their children to school and the socially optimal equilibrium is reached. However, if enforcement of legislation is too low, multiple equilibria emerge. In this case, child labor occurs more often among poor households, and compulsory schooling laws may have adverse welfare effects.

Child Labor and Resistance to Change

We study the interactions between technological innovation, investment in human capital and child labor. In our setting new technologies require new skills and new skills can be developed only through schooling. In a two-stage game, first firms decide on innovation, then households decide on education. In equilibrium the presence of inefficient child labor depends on parameters related to technology, parents’ altruism and the diffusion of firm property. When child labor exists, it is due to either firms reluctance to innovate or households’ unwillingness to educate or both. The optimal policy to eliminate child labor depends crucially on its underlying cause. We show that, in some cases, compulsory schooling laws or a ban on child labor are welfare reducing, while a subsidy to innovation is the right tool to eliminate child labor and increase welfare.

Financial Liberalization, Property Rights, and Growth in an Overlapping-Generations Model

In this paper we develop an endogenous growth model of open economies, where countries differ with respect to the quality of property rights. Within this context, we analyze two types of reforms. First, we look at growth and welfare effects of removing capital controls, given the degree of property rights protection. Second, we endogenize the quality of property rights and study the political support for a reform aimed at improving it. We show that, in countries where property rights are poorly protected, the liberalization of capital movements, that may or may not foster economic growth in the short-run, eliminates the possibility of sustained physical capital accumulation. Nevertheless, the removal of capital controls may benefit the agents alive at the time of liberalization, leaving a burden for future generations. Ceteris paribus, the political support for a reform of property rights will be stronger in the closed economy than in the open economy.

Bequest taxes, donations, and house prices

Abstract This paper is an empirical investigation into the effect of bequest taxes (estate or inheritance tax, in the US) and inter vivos real estate donations taxes (gift tax, in the US) on (i) house prices, (ii) house donations, and (iii) market transactions. In a simple model with intergenerational altruism, a lower tax rate unambiguously increases (i) and has an ambiguous effect on (ii) and (iii). We test these predictions using an original and unique data set containing information on sales, donations and real estate prices in 13 large Italian cities between 1993 and 2004. This period spans a major reform that first decreased and then abolished the inter vivos real estate donations tax and bequest tax in Italy. We find that the reform is associated with cumulative real appreciation of about 5% between 2001 and 2004, an increase in donations, and a decrease in market transactions over the same period.

Immigration Policy, Migrants' Selection and Human Capital Accumulation

This paper investigates the economic consequences of international migration from the point of view of destination countries. Consistently with international evidence on migration flows, we build a model where the migration rate is higher among the highly-educated. A negative relationship is shown to exist between the domestic wage level and the percentage of educated workers among immigrants, which raises interesting policy implications. In particular, the optimal immigration policy from the point of view of natives requires an immigration quota above a certain minimum level. Extending the analysis to a dynamic setting, we highlight additional effects of the immigration quota on human capital accumulation among natives.
