Normalizing biproportional methods
2002
International audience; Biproportional methods are used to update matrices: the projection of a matrix Z to give it the column and row sums of another matrix is R Z S, where R and S are diagonal and secure the constraints of the problem (R and S have no signification at all because they are not identified). However, normalizing R or S generates important mathematical difficulties: it amounts to put constraints on Lagrange multipliers, non negativity (and so the existence of the solution) is not guaranteed at equilibrium or along the path to equilibrium.
Production technologies in stochastic continuous time models
2011
Abstract Properties of dynamic stochastic general equilibrium models can be revealed by either using numerical solutions or qualitative analysis. Very precise and intuition-building results are obtained by working with models which provide closed-form solutions. Closed-form solutions are known for a large class of models some of which, however, have some undesirable features such as potentially negative output. This paper offers closed-form solutions for models which are just as tractable but do not suffer from these shortcomings.
Monetary Plurality in Economic Theory
2018
The objective of this article is to identify the monetary plurality in economic theory. We will try to throw light on the way in which theories are attracted towards both unicity and plurality, and more specifically by unification and diversification of money. It should also be noted, in this respect, that the economics of money has undergone considerable development since the 1970s. A survey of the diverse theories, whether mainstream or not, static or dynamic, holistic or individualistic, will reveal the surprising amount of attention devoted to the problem of monetary unicity and/or plurality. We base our presentation on two lines of thought: -The first of these lines concerns a situatio…
ESTIMATION OF AN EXTENDED SAM WITH HOUSEHOLD PRODUCTION FOR SPAIN 1995
2005
This paper implements the conceptual framework sketched by Pyatt (1990) to construct an extended Social Accounting Matrix for Spain in 1995 (ESAM-95) to consider, in addition to the market economy, the production of services provided by households through unpaid work. In doing so, the ESAM-95 integrates the accounts related to market activities (ESA accounts) with non-market activities (non-ESA accounts) in a consistent way. Additional classifications are introduced in both ESA and non-ESA accounts in order to disaggregate the institutional accounts by household type and those of production factors by educational level and gender. The extended SAM is useful to calibrate CGE models in which …
Spain in the euro: a general equilibrium analysis
2010
Bayesian dynamic stochastic general equilibrium (DSGE) models combine microeconomic behavioural foundations with a full-system Bayesian likelihood estimation approach using key macro-economic variables. Because of the usefulness of this class ofmodels for addressing questions regarding the impact and consequences of alternative monetary policies they are nowadays widely used for forecasting and policy analysis at central banks and other institutions. In this paper we provide a brief description of the two main aggregate euro area models at the ECB. Both models share a common core but their detailed specification differs reflecting their specific focus and use. The New Area Wide Model (NAWM)…
The shadow price of foreign exchange with minimum wages
2001
Abstract This note derives the shadow price of foreign exchange in a small open economy with minimum wage unemployment under tariffs, quotas and voluntary export restraints. The analysis is conducted in a dual general equilibrium framework with many goods and factors.
Fiscal sustainability in the EU: From the short-term risk to the long-term challenge
2015
Abstract The paper analyses fiscal sustainability of public debt using a dynamic computable general equilibrium model. First, we identify the short-term risk for fiscal stress at country level; second, we investigate the assumption of convergence towards the government debt threshold (medium-term challenge); and, third, the requirement that debt projections do not show unsustainable trends (long-term challenge). The empirical implementation includes 18 EU Member States. Our findings show that the constant tax rate that stabilizes the public debt converges to 50 percentage of GDP for all the sample countries and tax revenues are the main driving forces for fiscal sustainability. Also our fin…
Fiscal Devaluations in EMU
2013
2013SummaryWe use a small open economy general equilibrium model to analyse the effects of a fiscal devalua-tion in an EMU country. The model has been calibrated for the Spanish economy, which is a goodexample of the advantages of a change in the tax mix given that its tax system shows a positive biasin the ratio of social security contributions over consumption taxes. The preliminary empirical evi-dence for European countries shows that this bias was negatively correlated with the current accountbalance in the expansionary years leading up to the 2009 crisis, a period when many EMU membersaccumulated large external imbalances. Our simulation results point to significant positive effects of…
Is the Ghosh model interesting?
2009
International audience; The overall value of the Ghosh model is appraised. Its treatment of quantities and prices is scrutinized by examining the variant with data in quantities and prices, and the variant with data in value and price indexes. The methodology involves returning to the accounting equations and shows that: (i) the Ghosh model offers solutions of limited interest, being incapable of providing prices or price indexes separately from quantities; (ii) what is taken to be the equation of Ghosh's value model is actually that of Ghosh's physical model; (iii) the Ghosh model may serve for cost-push exercises, but the dual of the Leontief model performs the same task in a much simpler…
General Equilibrium Models of Monopolistic Competition: CRRA Versus CARA
2005
We analyze a class of "large group" Chamberlinian monopolistic competition models using multiplicatively quasi-separable (MQS) and additively quasi-separable (AQS) functions. We first prove that the MQS and AQS functions are equivalent to the "constant relative risk aversion" (CRRA) and "constant absolute risk aversion" (CARA) classes of functions, respectively. Whereas both approaches allow for closed-form solutions, only the AQS functions yield profit-maximizing prices that decrease in the mass of competing firms. We then characterize the equilibrium in both cases and discuss some possible applications of the AQS framework to trade, growth, and development.
