This paper aims to establish whether geographical proximity between multinational and domestic firms is relevant to the occurrence of FDI spillovers, by considering both horizontal and vertical spillovers. Using data for Portugal, this hypothesis is confirmed. In the case of horizontal...

In a series of papers, Benhabib, Schmitt-Grohé and Uribe (2001a, 2001b, 2001c, 2002 and 2004) have shown that active interest rules may lead to very unexpected consequences: indeterminacy, deflation traps, large cyclical instability, and can even lead to chaotic dynamics under standard sets of...

Resorting to an endogenous growth framework, the paper studies the implications of taking market clearing as a long term possibility rather than an every period implicit assumption, as is conventional in growth analysis. Under the proposed setup, the system may converge to a market equilibrium...

The pressure from national lobbies may lead governments to shift from an optimal into a non-optimal innovation policy. This paper examines the growth and welfare effects of optimal and non-optimal innovation policies. The non-optimal policy corresponds to a subsidy for national innovators that...

A local stability condition for the standard neo-classical Ramsey growth model is derived. The proposed setting is deterministic, defined in discrete time and expectations are formed through adaptive learning.

The increasing popularity of increasing block tariffs (IBT) for water is reflected in Portugal by a virtually universal implementation for residential use. IBT are often supported as a good tool for achieving the goals of equity, water conservation and revenue neutrality but seldom have they...

We explore the dynamic behavior of a New Keynesian monetary policy problem with expectations formed, partially, under adaptive learning. We consider two alternative cases: on the first setting, the private economy has the ability to predict rationally real economic conditions (the output gap)...

In this work we empirically test optimum currency area theory regarding the efficiency of two usual stabilization mechanisms for members of a given monetary union (the United States): federal transfers and migration. The US is recognized as a country where labor mobility between states is high....

Czech Republic, Hungary, and Poland are set to join the European and Monetary Union (EMU) in the near future. This paper offers a framework for the quantitative evaluation of the economic costs of joining the EMU. Using an open economy dynamic general equilibrium model with sticky prices, we...

New horizontally-differentiated goods involving product-specific network effects are quite prevalent. Consumers’ preferences for each of these new goods often are initially unknown. Later, as sales data begin to accumulate, agents learn market-wide preferences which thus become common...
