This paper demonstrates that the class of conditionally linear and Gaussian state-space models offers a general and convenient framework for simultaneously handling nonlinearity, structural change and outliers in time series. Many popular nonlinear time series models, including threshold, smooth...

We propose a theoretical framework for analyzing the problems associated to unilateral immigration policy in receiving countries and for evaluating the grounds for reform of international institutions governing immigration. We build a model with multiple destination countries and show that...

We study immigration policy in a small receiving economy under self-selection of migrants. We show that a non-discriminatory immigration policy choice affects and is affected by the migratory decisions of skilled and unskilled foreign workers. From this interaction multiple equilibria may arise,...

This paper studies the relationship between export policy and food prices. We show that, when individuals are loss averse, food exporters may use trade policy to shield the domestic economy from large price shocks. This creates a complementarity between the price of food in international markets...

This paper proposes and empirically tests a theory of entrepreneurial innovation in order to explain its high degree of concentration in space and time. In the model, a successful entrepreneurial project is the result of a search and matching process between entrepreneurs looking for funds and...

In an R&D-driven growth model with asymmetric fundamentals the steady state equilibrium R&D investments are industry-specific and they are such that R&D returns are equalized across industries. Return equalization, however, makes investors indifferent as to where to target research and, hence,...

Bank runs are relatively rare events characterized by highly pessimistic depositor’s expectations. How would pessimistic depositors expect to be treated in a bank run? How will this affect their behaviour? How can Banks handle this kind of risk? In the framework of a Diamond-Dybvig- Peck-Shell...
