In this paper we describe the medium-run macroeconomic effects and long-run development consequences of a financial Dutch disease that may takes place in a small developing country with abundant natural resources. The first move of such a peculiar Dutch disease is on financial markets. An...

We derive a New Keynesian Phillips Curve under Calvo staggered pricing and price competition. Firms strategic interactions induce price adjusters to change their prices less when there are more firms that do not adjust. This reduces the slope of the Phillips curve and generates an additional...

We study the effects of real uncertainty on long-run growth under different Taylor-type rules. We fi…nd a non-negligible relationship between real uncertainty and growth, which depends on the source of real uncertainty as well as the type of the Taylor rule considered. Importantly, when...

I consider a NK-DSGE model with endogenous firms' exit and entry together with a monopolistic competitive banking sector, where defaulting firms do not repay loans to banks. I show that the exit margin is an important shock transmission channel. It implies: i) an endogenous countercyclical...

We develop a stochastic general equilibrium model in which maintenance endogenously affects the capital depreciation rate. The model performs well in generating maintenance series that match closely existing survey-based measures for Canada. Maintenance is procyclical and comoves almost always...

In the light of the recent financial crisis, we investigate the effects generated by limited asset market participation on optimal monetary and fiscal policy, where monetary and fiscal authority are independent and play strategically. We find that limited asset market participation strongly...

Let (Xn) be a sequence of integrable real random variables, adapted to a filtration (Gn). Define: Cn = n^(1/2) {1/n SUM(k=1:n) Xk - E(Xn+1 | Gn) } and Dn = n^(1/2){ E(Xn+1 | Gn)-Z } where Z is the a.s. limit of E(Xn+1 | Gn) (assumed to exist). Conditions for (Cn,Dn) -- N(0,U) × N(0,V) stably...

An urn contains balls of d = 2 colors. At each time n = 1, a ball is drawn and then replaced together with a random number of balls of the same color. Let An =diag (An,1, . . . ,An,d) be the n-th reinforce matrix. Assuming EAn,j = EAn,1 for all n and j, a few CLT’s are available for such urns....

We propose a model characterized by strategic interactions among an endogenous number of producers and search and matching frictions in the labor market. In line with U.S. data: (i) new firms account for a relatively small share of overall employment, but they create a relevant fraction of new...
