The dynamics of export market exit and firm closure have found limited attention in the new heterogeneous-firms trade literature. In fact, several of the predictions on firm survival and exit stemming from this new class of models are at odds with the stylized facts. Empirically, higher productivity firms survive longer, most firm closures are young firms, higher productivity exporters are more likely to continue to export compared to less productive exporters and market exits as well as firm closures are typically preceded by periods of contracting market shares. The present paper shows that the simple inclusion of exogenous economy wide technological progress into the standard Melitz (2003) model generates a tractable dynamic framework that generates endogenous exit decisions of firms in line with the stylized facts. Furthermore, we derive the effects of faster technological progress and trade liberalization on export market exit and firm closure. 相似文献

Drawing on the theory of organisational routines as generative systems, we deploy a critical realist approach based on Searle's philosophy of language to analyse the generative mechanisms that specify the pre-conditions for recognisable, repetitive patterns of interdependent activities. Using the example of the organisational routines implemented in Germany to monitor the allocation and disbursement of the European Social Fund, we contend that constitutive rules of the type “X counts as Y in context C” are at the very centre of organisational routines. Such rules consist of generative mechanisms that account for the emergence of the ostensive aspects of organisational routines out of artefacts and/or procedures in a social structure of power relations. We further claim that, far from being proxies for the ostensive aspects of routines, artefacts whether tangible or intangible are instantiations of such ostensive aspects on a par with any other performative aspects of routines. On this basis, a re-conceptualisation and a re-labelling of the ostensive and performative aspects of routines are proposed. The former are the result of the activation of systems of constitutive rules, i.e. actual routines in critical realist terminology, the latter are patterns of interdependent activities instantiating the ostensive aspects of routines, i.e. empirical routines in critical realist terminology. Implications for theory and practice are discussed by developing a model of organisational routines that interweaves extant research streams. 相似文献

Technology and knowledge are two key components for economic growth; however, the two concepts are not consensually defined. This paper proposes a model to assess and quantify the technology contribution to the value-adding process. The methodological approach implied building an operational concept for technology that is independent of the concepts of knowledge and capital. As such, technology could be interpreted and quantified as an input parameter in a new production model. This model interprets and assesses, separately, the value contributions of the uses of technology, of knowledge and of capital in a production process, defining the Technology Index for that process. The model is applied to manufacturing sectors of seven European countries, quantifying their respective dependences on technology. A comparison of the Technology Index proposed here is made with the OECD's Technology Intensity factor, arguing that the former reflects the technology dependence better that the latter. Accordingly, a criterion for classifying the economic sectors' dependence on technology is proposed. A main contribution from this study is an objective classification criterion for technology dependence of firms and economic sectors. It also provides an easy benchmark procedure for knowledge and capital dependence between firms and sectors. 相似文献

The relationship between social and financial performance (CSP – FP) has been a main objective in the literature on business
management, as it would provide an economic justification for the social investment insofar as it contributes to the creation
of value. This relationship has been empirically tested by several authors though without using a theoretical model that sustains
this relationship. The aim of this article is to propose a theoretical model of the process of the creation of value from
the reputation generated by companies, integrating the factors that have been shown to be more relevant in this process from
previous research, in such a way that hypotheses are put forward regarding the existence of this relationship and the factors
that determine it. Finally, an empirical test is performed using the 100 most prestigious companies operating in Spain during
2004. 相似文献

Ordering univariate distributions by entropy and variance 总被引:1,自引:0,他引:1
This paper examines the role of variance and entropy in ordering distributions and random prospects. There is no universal relation between entropy and variance orderings of distributions. But we place their relationship in the context of a stronger ordering relation known as dispersion ordering. Further, some conditions are identified under which variance and entropy order similarly when continuous variables are transformed. We also analyze parametric changes which do not disturb the agreement between these rankings. The results are conveniently tabulated in terms of distribution parameters. 相似文献

The economic and political changes which are taking place in Europe affect interest rates. This paper develops a two-factor model for the term structure of interest rates specially designed to apply to EMU countries. In addition to the participant country's short-term interest rate, we include as a second factor a 'European' short-term interest rate. We assume that the 'European' rate follows a mean reverting process. The domestic interest rate also follows a mean reverting process, but its convergence is to a stochastic mean which is identified with the 'European' rate. Closed-form solutions for prices of zero coupon discount bonds and options on these bonds are provided. A special feature of the model is that both the domestic and the European interest rate risks are priced. We also discuss an empirical estimation focusing on the Spanish bond market. The 'European' rate is proxied by the ecu's interest rate. Through a comparison of the performance of our convergence model with a Vasicek model for the Spanish bond market, we show that our model provides a better fit both in-sample and out-of sample and that the difference in performance between the models is greater the longer the maturity of the bonds.

A regulated upstream monopolist provides an input to firms in a downstream market. If the monopolist enters the downstream market, a natural concern is that it will act so as to raise its downstream rivals' costs. An offsetting incentive is that a higher downstream price will reduce demand for the input, which reduces the monopolist's profit. Conditions under which one incentive dominates the other are derived. The monopolist may desire to lower its downstream rivals' costs rather than raise them. These findings suggest that regulatory policy towards such downstream entry should not focus exclusively on the ability to discriminate. 相似文献
