Standard international real business cycle models are generally unable to replicate the observed comovements of all the main aggregate variables: in particular, they generate low or negative international comovements in output, investment, and labour. I simulated a two-country, two-sector...

A restricted solid-on-solid model where surface relaxation occurs by atom desorption and by surface diffusion is introduced and studied in 1+1 dimensions. The interface profile is mapped onto a four-vertex model and the kinetic equation describing the moving surface is solved exactly for small...

The paper discusses conditions to identify a stochastic Ramsey growth model from loglinear growth regressions.

An important question is whether underdeveloped countries will converge to the per-capita income level of developed countries. Economists have used the disequilibrium adjustment property of growth models to justify the view that convergence should occur. Unfortunately, the empirical literature...

We propose a method to compute equilibria in dynamic models with several continuous state variables and occasionally binding constraints. These constraints induce non-differentiabilities in policy functions. We develop an interpolation technique that addresses this problem directly: It locates...

We consider the problem of the generation of adaptive grids, where, for a given domain Ω, we have to compute a partition that depends on a given map f providing the desired local mesh size. We propose a numerical method for the solution of this problem in the case of planar quadrilateral grids....

The rapid growth in demand and supply of sophisticated data mining and analytical decision tools calls for research to understand the value of learning, as well as how learning interacts with firms’ day-to-day marketing strategies.In this paper, we consider a market in which the firm can...

We study an order promising problem in a multiclass, available-to-promise (ATP) assembly system in the presence of <i>pseudo orders</i>. A pseudo order refers to a tentative customer order whose attributes, such as the likelihood of an actual order, order quantity, and confirmation timing, can change...
