    Does Money Matter for the Identification of Monetary Policy Shocks: A DSGE Perspective.

    This paper investigates how the identification assumptions of monetary policy shocks modify the inference in a standard DSGE model. Considering SVAR models in which either the interest rate is predetermined for money or these two monetary variables are simultaneously determined, two DSGE models are estimated by Minimum Distance Estimation. We emphasize that real balance effects are necessary to replicate the high persistence implied by the simultaneity assumption. In addition, the estimated monetary policy rule is strongly sensitive to the identification scheme. This suggests that the way to introduce money in the identification scheme is not neutral for estimation of DSGE models.SVAR model; DSGE model; Non recursive identification; Money.

    Firm Entry, Inflation and the Monetary Transmission Mechanism

    This paper estimates a business cycle model with endogenous firm entry by matching impulse responses to a monetary policy shock in US data. Our VAR includes net business formation, profits and markups. We evaluate two channels through which entry may influence the monetary transmission process. Through the competition effect, the arrival of new entrants makes the demand for existing goods more elastic, and thus lowers desired markups and prices. Through the variety effect, increased firm and product entry raises consumption utility and thereby lowers the cost of living. This implies higher markups and, through the New Keynesian Phillips Curve, lower inflation. While the proposed model does a good job at matching the observed dynamics, it generates insufficient volatility of markups and profits. Estimates of standard parameters are largely unaffected by the introduction of firm entry. Our results lend support to the variety effect; however, we find no evidence for the competition effect.entry, inflation, monetary transmission, monetary policy, extensive margin

    On the Recovery Path during a Liquidity Trap: Do Financial Frictions Matter for Fiscal Multipliers?

    Get PDF
    This paper investigates the effects of a fiscal stimulus when financial frictions and a liquidity trap are present. These two conditions make a government spending expansion and a reduction in capital income taxes more efficient in stimulating output. In contrast, a reduction in labor income taxes may aggravate the economic conditions. In addition, small implementation delays in government spending may result in big spending multipliers in the short run. All of these results rely partly on the dynamic interaction between inflation and the external finance premium. Lastly, simulations of the ARRA stimulus package predict that the output gains due to the presence of financial frictions may lie between 1.3 % and 2.5 % of GDP.Zero Lower Bound, Financial Accelerator, Fiscal Policy

    Investigating the Zero Lower Bound on the Nominal Interest Rate under Financial Instability

    Get PDF
    This paper introduces a zero lower bound constraint on the nominal interest rate in a financial accelerator model with nominal and real rigidities. We .rst analyze the implicationsfor aggregate dynamics of binding the zero lower bound for shocks that depress the nominalinterest rate. We include a sudden decrease in the value of the business sector net worth and an increase in its returns volatility, as two financial shocks that originate in the endogenous credit market of the model. We then explore the effects of the central bank management of expectations and a fiscal stimulus in a deep recession scenario, where the interest rate initially binds its zero bound. We find that a commitment by the central bank to keep the interest rate low for more time than prescribed by a typical interest rate rule may indeed reduce the volatility of output and inflation. For government purchases, we find a fiscal multiplier greater than one for at least 5 quarters. This is due to the presence of the zero lower bound and the Fisher (1933)’s debt-deflation channel, which implies that government spending may reduce the business sector risk premium and thus the cost of investment.monetary economics ;

    How Well Does a Small Structural Model with Sticky Prices and Wages Fit Postwar U.S. Data?

    Get PDF
    In this paper, we ask whether a small structural model with sticky prices and wages, embedding various modelling devices designed to increase the degree of strategic complementarity between price-setters, can fit postwar US data. To answer this question, we resort to a two-step empirical evaluation of our model. In a first step, we estimate the model by minimizing the distance between theoretical autocovariances of key macroeconomic variables and their VAR-based empirical counterparts. In a second step, we resort to Watson's (1993) procedure [Measures of fit for calibrated models. Journal of Political Economy 101 (6), 1011.1041] to quantify the model's goodness-of-fit. Our main result is that the combination of sticky prices and sticky wages is central in order to obtain a good empirical fit. Our analysis also reveals that a model with only sticky wages does not perform well according to Watson's criterion (1993).Sticky prices ; Sticky wages ; Strategic complementarities ; Watson's test.

    Employment, Hours and the Welfare Effects of Intra-Firm Bargaining

    Ce Working Paper fait l'objet d'une publication in Journal of Monetary Economics, Elsevier 〈https://www.sciencedirect.com/science/article/abs/pii/S0304393218305294〉〈hal-01995026〉Intra-firm bargaining between a multiple-worker firm and an individual employee leads to overhiring. Taking advantage of the decreasing returns to scale in employment, the firm can reduce the marginal product by hiring an additional worker, thereby reducing the bargaining wage paid to all existing employees. We show that this externality is amplified when firms can adjust hours per worker as well as employment. Hours are too low at the steady state. This misallocation of labor leads to sizeable welfare losses. Our finding is important for economies in which hours adjustment play an important role as it does in many Euro Area countries

    Une Ă©valuation structurelle du ratio de sacrifice dans la zone euro.

    In this paper, we seek to estimate the sacrifice ratio of the euro area using a small DSGE model where prices and wages are sticky. We estimate model's parameters so as to minimize the distance between VAR-based and model-based covariances of a set of variables. The estimated value of the sacrifice ratio reaches 1.30%. In a second step, we proceed to a set of counterfactual exercises in order to highlight the link between the sacrifice ratio and the degree of prices and wages stickiness. We obtain that a decrease of prices stickiness does not necessary result in a decrease of the sacrifice ratio. In addition, the sacrifice ratio rises with the degree of wage stickiness.Sacrifice ratio ; Sticky prices and sticky wages ; DSGE model.
