Strategic Interactions in a Growth Model with Infrastructure Capital

A dynamic game growth model with infrastructure capital is analyzed and it is shown that the pattern of growth can be either endogenous or exogenous depending on agents’ commitment behavior. If the agents commit their future actions, there is a unique Nash equilibrium with endogenous growth. However, if they cannot commit their future actions and they condition their actions on the state variable at each time, then for any level of infrastructure capital there exist infinitely many equilibria: some of them exhibit endogenous growth and others show no growth in the long run (or even in the short run).

Long-run Positions and Short-run Dynamics in a Classical Growth Model

The aim of this paper is to study the qualitative impact of short-run disequilibria on long-run positions. In this perspective, we refer to a classical framework. We underline that one-sector classical growth models only deal with perfectly adjusted situations (steady-state equilibria). Such models assume that short-run dynamics are neutral in the long run which means that the steady state is defined independently of the transient dynamics. In order to show that this situation is not always realized, we propose a modified version of Kurz's growth model (“Technical change, growth and distribution: a steady-state approach to ‘unsteady’ growth”, in Kurz H. D.: Capital Distribution and Effective Demand, Blackwell, Oxford, 1990, pp. 210–239) that integrates short-run disequilibria. We obtain dynamics that exhibit a multiplicity of equilibria. Therefore, short-run events can no longer be neglected, since they contribute to the emergence of the long-run equilibrium.     

Aggregate Demand and Endogenous Growth: a Generalized Keynes-Kaldor Model of Economic Growth

This paper presents a generalized Keynes-Kaldor growth model which incorporates both the Cambridge theory of income distribution and endogenous technical change. Within the model, the rate of aggregate demand growth affects both the level of aggregate demand and the rate of output growth. However, demand growth management can only be used to shift the economy from low to high growth equilibria, and cannot produce continuous adjustments in the equilibrium rate of growth. This reveals that management of the growth trajectory is a qualitatively different problematic from management of the level of output. Lastly, the model highlights ambiguities regarding the adjustment dynamics of demand growth.

A Linear Multisector Model of “Endogenous” Growth and the Problem of Capital

In this paper a linear multisector model of “endogenous” growth with heterogeneous capital goods is elaborated. The purpose of this exercise is to show that this kind of model is exempt from the capital theory critique put forward against the conventional long-period neoclassical growth model á la Solow. This confirms previous claims that at least some of the “new” growth models are somewhat extraneous to neoclassical analysis and actually exhibit the logical structure of classical theory. In addition it is shown that the use of an intertemporal analysis to establish a correct long-period position is not necessary and that the use of the long-period method may speed up the elaboration of new scientific results.

制度演化的一种可能机制 --外部性的转化和平衡

经济系统是一个由相互作用着的主体构成的关系网络。产权是有价值的规则系统,产权的价值是在主体之间相互作用的过程中确定的,它因人而异和因时而异的,这就使得产权的交换和产权结构演化成为可能。经济系统中主体的“生态位”是指该主体所拥有的产权以及相应的行为规则集合。生态位的重叠导致外部性的产生,而制度的涌现和演化过程就是外部性的产生、转换和平衡过程。     

Corporate Social and Financial Performance Re-Examined: Industry Effects in a Linear Mixed Model Analysis

In this research, we shed new light on the empirical link between corporate social performance (CSP) and corporate financial performance (CFP) via the application of empirical models and methods new to the CSP?CCFP literature. Applying advanced financial models to a uniquely constructed panel dataset, we demonstrate that a significant overall CSP?CCFP relationship exists and that this relationship is, in part, conditioned on firms?? industry-specific context. To accommodate the estimation of time-invariant industry and industry-interaction effects, we estimate linear mixed models in our test of the CSP?CCFP relationship. Our results show both a significant overall CSP effect as well as significant industry effects between CSP and CFP. In conflict with expectations, the unweighted average effect of CSP on CFP is negative. Our industry analysis, however, shows that in over 17% of the industries in our sample, the effect of CSP on CFP for socially responsible firms is positive. We also examine the multidimensional nature of the CSP construct in an industry context by exploring the CSP dimension?Cindustry nexus and identify dimensions of social performance that are associated with either better or worse financial performance. Our results confirm the existence of disparate CSP dimension?Cindustry effects on CFP, thus our results provide important and actionable information to decision makers considering whether and how to commit corporate resources to social performance.

Trade Growth in a Heterogeneous Firm Model: Evidence from South Eastern Europe

In 2007 a free trade area (BFTA) will be created in the Balkans. In this paper we study BFTA‐induced trade growth in the SEE. Given that welfare impacts associated with trade growth depend on the growth channels, more goods and varieties exported or at higher price or more volume of exported goods and varieties, we study the structure of integration‐induced export growth in the Balkans. Given that no firm‐level trade data is available for the Balkans, we adopt the heterogeneous firm framework, which allows to decompose aggregate trade growth into intensive margin of trade and extensive margin of trade using only aggregate trade data. Our empirical findings predict that the BFTA would primarily increase the export volume through a growing number of shipments (the extensive margin of trade) suggesting that the actual welfare gains from the trade growth in the Balkans might in fact be larger than predicted in previous trade studies. We also found that reducing variable trade costs leads to higher export growth rates compared to reducing fixed trade costs by the same percentage.     

A Model of Growth and Conflict Inflation for a Small Open Economy

Several models of conflict inflation have been developed within the structuralist tradition. This paper differs from such works by assuming full capacity utilization in a small open economy. We introduce the exchange rate as a participant in the theory of inflation and distribution, and analyze two closures: the trade deficit as a market clearing mechanism, and a foreign exchange constrained economy. It is found that wage rigidity and exchange rate flexibility can lead to instability. The main conclusions do not change when we allow for continuous substitution between capital and labor.     

中国出口增长的就业效应:基于CGE模型的分析

本文通过构建一个具有中国劳动就业结构特征的CGE模型,以2008年下半年国际金融危机以来全球经济增长变化和中国实施经济刺激计划为背景,设计不同的情景方案,模拟分析了中国出口变化对劳动就业的影响效应。结果显示:出口增长1个百分点可以实现0.088个百分点的非农就业增长。但出口就业效应相对于不同的产业部门和就业群体而言具有明显的差异,出口下降将导致纺织、制造业等部门就业人数的显著减少,农民工就业压力明显超过城镇就业。因为出口就业效应显著低于投资就业效应,国际金融危机以来我国劳动就业不仅在数量上经历了从大幅减少到显著增长的突变,同时在结构上也出现了从可贸易部门向非贸易部门的转换。权衡劳动力比较优势利用和产业结构升级,重视就业基数大、出口就业弹性低的服务业部门劳动力吸收能力的提高,实现就业的结构性均衡增长,应成为确保我国未来就业安全的政策方向。

External Linkages and Economic Growth in Colombia: Insights from a Bayesian VAR Model

This paper investigates the sensitivity of Colombian GDP growth to the surrounding macroeconomic environment. We estimate a Bayesian VAR model with informative steady‐state priors for the Colombian economy using quarterly data from 1995 to 2007. A variance decomposition shows that world GDP growth and government spending are the most important factors, explaining roughly 17 and 16 per cent of the variance in Colombian GDP growth respectively. The model, which is shown to forecast well out‐of‐sample, can also be used to analyse alternative scenarios. Generating both endogenous and conditional forecasts, we show that the impact on Colombian GDP growth of a substantial downturn in world GDP growth would be non‐negligible but that the decline still would be mild by historical standards.
