A rational expectations model for simulation and policy evaluation of the Spanish economy
2010
This paper presents the model used for simulation purposes within the Spanish Ministry of Economic Affairs and Finance. REMS (a Rational Expectations Model for the Spanish economy) is a small open economy dynamic general equilibrium model in the vein of the New-Neoclassical-Keynesian synthesis models, with a strongly micro-founded system of equations. In the long run REMS behaves in accordance with the neoclassical growth model. In the short run, it incorporates nominal, real and financial frictions. Real frictions include adjustment costs in consumption (via habits in consumption and rule-of-thumb households) and investment into physical capital. Due to financial frictions, there is no per…
Sticky-price models and the natural rate hypothesis
2005
Abstract A major criticism of standard specifications of price adjustment in models for monetary policy analysis is that they violate the natural rate hypothesis by allowing output to differ from potential in steady state. In this paper we estimate a dynamic optimizing business cycle model whose price-setting behavior satisfies the natural rate hypothesis. The price-adjustment specifications we consider are the sticky-information specification of Mankiw and Reis (Sticky information versus sticky prices: a proposal to replace the new Keynesian Phillips curve. Quarterly Journal of Economics 117, 1295–1328) and the indexed contracts of Christiano et al. (Nominal rigidities and the dynamic effe…
Change of regime and Phillips curve stability: The case of Spain, 1964–2002
2007
Following the emergence of the Lucas critique, traditional Phillips curves relating inflation to a measure of the level of activity, and augmented to include past inflation (assumed to proxy expected inflation), have been deemed to be highly unstable over time. In this paper we try to investigate, using recent econometric developments, whether such a statement can be supported over a long time period. In the empirical application, we analyze the case of Spain along the period 1964–2002.
Labour Market Institutions and Inflation Differentials in the EU
2015
Adopting a simple Phillips curve framework, we show that different labour market institutions across EU countries are associated with significant differences in the response of inflation to unemployment and exchange rate shocks. More wage coordination and higher union density flatten the Phillips curve and increase the inflation response to the real exchange rate, i.e. the exchange rate pass-through. In addition, using a new approach to the classification of goods and services as "traded" or "non-traded", we show that both these institutional effects are significantly stronger for the more exposed (traded) sector.
Inflation and optimal monetary policy in a model with firm heterogeneity and Bertrand competition
2018
Abstract We study the joint implications of heterogeneity of total factor productivity and strategic price interactions between firms on the dynamics of inflation and the design of optimal monetary policy. In this setting, more productive firms respond less to shocks affecting their marginal costs than less productive firms. As a consequence, economies with a larger proportion of highly productive firms face a flatter Phillips curve. Moreover, when these two features concur, the Ramsey problem gives rise to an optimal non-zero long run inflation that amplifies the differences in relative prices between more efficient and less efficient firms, thus increasing the market share of the former. …
Market Polarization and the Phillips Curve
2021
The Phillips curve has flattened out over the last decades. We develop a model that rationalizes this phenomenon as a result of the observed increase in polarization in many industries, a process along which a few top firms gain an increasing share of their industry market. In the model, firms compete a la Bertrand and there is exit and endogenous market entry, as well as optimal up and downgrading of technology. Firms with larger market shares find optimal to dampen the response of their price changes, thus cushioning the shocks to their marginal costs through endogenous countercyclical markups. Thus, regardless of its causes (technology, competition, barriers to entry, etc.), the recent i…
Wage Drift: Phillips Curve vs Bargaining Models
1994
: The purpose of this paper is to shed light on the debate on market- versus bargaining-determined total earnings by examining whether models of wage drift based on wage-bargaining considerations empirically outperform models based on simple ad hoc formulations relating wage drift to excess demand for labour. The task is carried out by investigating the empirical performance of two bargaining models and two Phillips curve models in the context of data on the Finnish metal industry. The results suggest that the former perform better than the latter, thus providing support for the hypothesis that total earnings are bargaining-determined. Furthermore, the results are in line with the view that…
Active monetary policy and instability in a phillips curve system
1998
The presence of nonlinearities in a Phillips curve system yields to complex dynamics, i.e., cyclical behavior that may (under some parametric set) become chaotic. This paper extends these conclusions by including an active monetary policy. We show how stabilization policy may lead to amplified instabilities and that agents' expectations tend to play a key role in the amount of these instabilities.
