Multiple equilibria in a cash-in-advance two-sector economy 总被引:1,自引:0,他引:1
Stefano Bosi Francesco Magris Alain Venditti 《International Journal of Economic Theory》2005,1(2):131-149
We consider a two-sector infinite horizon economy with a fractional cash-in-advance constraint on consumption expenditures. This formulation allows us to consider a steady-state velocity of money that is strictly greater than one and, therefore, provides a more plausible framework than the standard formulation in which all the consumption purchases are paid cash. We prove that the steady state is bound to be indeterminate and multiple equilibria occur when the share of the liquidity constraint is low enough and that a capital-intensive investment good or a strongly capital-intensive consumption good improve considerably the scope for indeterminacy. As a consequence, we show that without any restriction on the elasticity of intertemporal substitution in consumption, multiple equilibria might occur if the velocity of money is greater than a critical bound that is compatible with empirical estimates. 相似文献

We combine Hotelling’s model of product differentiation with tie-in sales. A monopolist in one market competes with another
firm in a second market. In equilibrium firms choose zero product differentiation. Due to the tying structure no firm can
gain the whole market by a small price reduction. A differentiation effect due to tie-in sales leads to this equilibrium stability.

Mixed causal–noncausal autoregressive (MAR) models have been proposed to model time series exhibiting nonlinear dynamics. Possible exogenous regressors are typically substituted into the error term to maintain the MAR structure of the dependent variable. We introduce a representation including these covariates called MARX to study their direct impact. The asymptotic distribution of the MARX parameters is derived for a class of non-Gaussian densities. For a Student likelihood, closed-form standard errors are provided. By simulations, we evaluate the MARX model selection procedure using information criteria. We examine the influence of the exchange rate and industrial production index on commodity prices. 相似文献

The existence and strong consistency of the maximum likelihood estimator are analyzed in the context of dichotomous logit models. Sufficient conditions are given for the asymptotic normality of this estimator. 相似文献

We consider a discrete-time two-sector CES economy with sector specific external effects in which factor substitutability differs across sectors. For this general model, we provide sufficient conditions on the elasticities of capital/labor substitution for local indeterminacy of equilibria.Acknowledgement We would like to thank two anonymous referees, the editor Dieter Bös and Tapan Mitra for comments on an earlier version of this paper, previously entitled Capital Depreciation, Factors Substitutability and Indeterminacy, which allowed us to improve considerably the results. 相似文献

We study the relation between international trade and the gains to reform labor markets by removing firing restrictions. We find that trade linkages imply substantially smaller benefits to reform than those calculated in the closed economy general equilibrium model of Hopenhayn and Rogerson [Hopenhayn, Hugo, Rogerson, Richard, 1993. Job Turnover and policy evaluations: a general equilibrium analysis. Journal of Political Economy 101 (5), 915–938 October]. When economies trade, labor market policies in one country spill over to other countries through their effect on the terms of trade. A key finding in the open economy is that the share of the welfare gains from domestic labor market reform exported substantially exceeds the share of goods exported. Thus, with international trade, a country retains little to no benefit from unilaterally reforming its labor market. A coordinated elimination of firing taxes yields considerable benefits. We also find that the U.K. benefits from labor market reform by its continental trading partners. These insights provide some explanation for recent efforts toward labor market reform in the European Union. 相似文献

We examine stock returns of firms with international exposure. Our empirical work relies on Campbell's variance decomposition framework. Not surprisingly, we find that the volatility of discount rate and cash flow news increase with the degree of international exposure. As firms globalize, the cash flow effect is good news, while the discount rate effect amounts to bad news. The surprising result is that the covariance between the news terms increases with international exposure. This finding provides indirect evidence for the proposition that foreign exchange (FX) risk is a priced factor in the cross‐section of risk‐adjusted expected returns.
