We build a general equilibrium model in which both illegal immigration and the size of the informal sector are endogenously determined. In this framework, we show that indirect policy measures such as tax reduction and detection of informal activities can be used as substitutes for border...

This paper examines the role of public education in the context of parental migration, and it studies the effects of an expansive income tax policy that is adopted to increase public education expenditure per pupil. It is shown that such a policy may exacerbate income inequality in the long run...

We solve an optimal growth model in continuous space, continuous and bounded time. The optimizer chooses the optimal trajectories of capital and consumption across space and time by maximizing an objective function with both space and time discounting. We extract the corresponding Pontryagin...

We build a Susceptible-Infected-Vaccinated Economic two-sector growth model to study the evolution of inequality in an economy with two groups of workers, who are differently exposed to a transmissible disease. We show that the economy can lead to various scenarios in the long run, which range...

This paper presents a first model integrating the relation between biodiversity loss and zoonose pandemic risks in a general equilibrium dynamic economic set-up. The occurrence of pandemics is modeled as Poissonian leaps in economic variables. The planner can intervene in the economic and...

The paper reexamines Lipset’s theory of democratization, by distinguishing the role of (economic) development from that of education, inequality, and (natural) resources. We highlight two contrasting effects of education and human capital accumulation. On the one side, education prompts...

This paper extends the standard neoclassical model by considering a technology sector through which an economy with limited human capital attempts to catch up with a given 'locomotive' pushing exogenously technical progress. In periods of technological stagnation, economies close enough to the...

This paper presents a non-technical overview of the recent investment literature with a special emphasis on the connection between technological progress and the investment decision. First of all, we acknowledge that some dramatic advances have been made in the 1990s in understanding and...

We develop a continuous time dynamic game to provide with a benchmark theory of Arab Spring-type events. We consider a resource-dependent economy with two interacting groups, the elite vs. the citizens, and two political regimes, dictatorship vs. a freer regime. Transition to the freer regime...
