In the following codes, I employ two methods to solve rational expectations models. The resolution is performed via the dynare package requires Matlab or octave initially developed by Michel Juillard. All theses codes are based on the generalized Schur form to solve a systems of linear expectational difference equations. The Cobb-Douglas production function now combines labor, physical capital and technology to produce goods: where is an IID exogenous disturbance associated with a productivity shock.

This feature captures the autocorrelation of consumption observed in the data. Thus the utility function subject to external habits reads as follows: RBC Model with investment adjustment costs Dynare Codes Matlab Codes To introduce asset price fluctuations, households supplying investment goods face an investment adjustement costs given by: The law of motion of capital with investment adjustment costs is defined by: These costs drive a wedge between the price of assets and goods and offer a tradeoff beetwen capital goods and riskless bonds.

CEE introduce variable capital utilization in order to match the data. The amount of capital utilized in the production is: This equation shows that capital requires one period to be installed i.

The Cobb-Douglas production function now combines technology, labor and utilized capital: The variable utilization of capital incurs a variable cost, denoted. Melitz, M.

Dynare Codes Matlab Codes Our economy is populated by a large number of households , the utility function of the representative household is defined by: where is the risk aversion and is the frischian elasticity of labor. The welfare index is determined by the sum of the current and expected utilities: Additionally, the production function follows a Cobb-Douglas technology: where is an IID exogenous disturbance associated with a productivity shock.

The resources constraint is given by the demand from households and authorities: where is a IDD normal shock, is the steady state level of the GDP and is the spending to GDP ratio. RBC Model with external habits. Dynare Codes Matlab Codes In this setting, we consider that each household has external consumption habits. Thus the utility function subject to external habits reads as follows:.

RBC Model with investment adjustment costs. Dynare Codes Matlab Codes To introduce asset price fluctuations, households supplying investment goods face an investment adjustement costs given by: The law of motion of capital with investment adjustment costs is defined by: These costs drive a wedge between the price of assets and goods and offer a tradeoff beetwen capital goods and riskless bonds.

RBC Model with variable capital utilization. New Keynesian Model codes NK. The New Keynesian Model. Dynare Codes Matlab Codes The standard New Keynesian model assumes that monopolistic competitive firms are price makers on the good market, but they cannot adjust prices as prices are sticky.

There are two ways of introducing nominal rigidities: the Rotemberg way, see Rotemberg and the Calvo price setting, see Calvo I present here the Calvo price setting.

Among these firms, a fraction is not allowed to set price, then the price remains the same such that. For the share of firms allowed to reset their price, each firm maximizes the expected sum of profits: under the demand constraint from final goods packers. The FOC from the previous problem, combined with the aggregate price equation and taken in logs gives rise to the New Keynesian Phillips Curve NKPC : Finally, to close the model, we suppose that monetary authority controls the nominal interest rates and is concerned by both price and GDP growths.

New Keynesian Model with price indexation. They include in New Keynesian setup an indexation mechanism when firms are setting their price. In particular in our model, for the fraction of firms not allowed to reset price, their selling price remains the same such that and indexed on past inflation in a proportion.

Concerning the share of firms allowed to reset their price, each firm maximizes the expected sum of profits: under the demand constraint from final goods packers. Published codes. We build and estimate a two-country DSGE model with corporate and interbank cross-border loans, Core-Periphery diverging financial cycles and a national implementation of coordinated macroprudential measures based on Countercyclical Capital Buffers.

I provide here the estimated model at the mode , not the optimization exercise. We find that country-adjusted macroprudential measures lead to significant welfare gains with respect to a uniform macroprudential policy rule that reacts to union-wide financial developments.

However, peripheral countries are the winners from the implementation of macroprudential measures while core countries incur welfare losses, thus questioning the interest of adopting coordinated macroprudential measures with peripheral countries. Financial Frictions and the Extensive Margin of Activity. We extend the initial framework of Bilbiie, Ghironi and Melitz and augment it with real, nominal and financial frictions to get a data friendly model. The model is estimated using Bayesian techniques for the US economy.

I share the model which is calibrated on the posterior estimated mean value of deep parameters and shocks, I also share the data involved in the estimation exercise. I cannot give the data, these are internal to ECB and cannot be shared.

The given mod file is calibrated on the estimated parameters and shocks in our paper at the posterior mean. A Simple dynamic 3-equation New Keynesian Model.

This paper aims at introducing New Keynesian Macroeconomics for graduate students.

## DSGE Dynare Model Matlab Codes

A Short Course on. By Lawrence J. I will discuss the construction and use of dynamic stochastic general equilibrium DSGE models in the analysis of monetary policy. We review the solution and estimation of DSGE models. We will review the use of maximum likelihood and Bayesian estimation methods, methods that make use of estimated Vector Autoregressions VAR , as well as methods based on single equation estimation.
