Can active Taylor rules (i.e. monetary rules where the nominal interest rate responds more than proportionally to inflation) deliver global equilibrium uniqueness in small open economies? By studying the local and global dynamics of a standard small open economy we point out the misleading...

We argue that cross-country convergence of output per capita should be examined in a fractional-integration time-series context and we propose a new empirical strategy to test it, which is the first one that discriminates between fractional long-run convergence and fractional catching-up. The...

Inflation volatility has significantly declined over the last 20 years in the U.S. To find out why, I follow a structural approach. I estimate a complete New Keynesian model which imposes cross-equation restrictions on the time series of inflation, the output gap and the interest rate. I perform...

The assumption of internationally identical factor intensity techniques may be one of the major causes of the HOV model's poor performance. To relax this assumption, detailed input-output data are required to compute the factor intensity techniques used in different countries; however, these...

This paper considers trade in an asymmetric 2x2x2 world, the two countries being labelled America and Europe. In America, the labor market is perfectly competitive, with flexible wages ensuring full employment. Europe faces unemployment due to efficiency wages. We derive the conditions for there...

We introduce technological differences in a Heckscher-Ohlin model and study how the technology and endowment differences interact to determine the effects of trade on factor prices. When the endowment effect is dominant in determining the autarky relative factor prices, the relative factor...

This paper explores the link between an environmental policy and economic growth employing an extension of the Neoclassical Growth Model. We include a state equation to renewable natural resources, and consider natural resources as a component of the aggregate productivity. It is assumed that...

In spite of fiat money is useless in a standard Arrow-Debreu model, in this paper we will show that this does not hold true anymore when goods are indivisible. In our setting, although fiat money yields no utility, its price will always be positive and the set of equilibrium allocations changes...

This paper analyzes a stochastic model of evolution in normal form games. The long-run behavior of individuals in this model is investigated in the limit where mutation rates tend to zero, while the expected number of mutations, and hence population sizes, tend to infinity. It is shown that...

This paper studies a competitive market model for trading indivisible commodities. Commodities can be desirable or undesirable. Agents' preferences depend on the bundle of commodities and the quantity of money they hold. We assume that agents have quasi-linear utilities in money. Using the...
