In a previous paper, Delgado, Fariñas and Ruano (2002) report TFP differences between exporters and non‐exporters on the basis of a sample of Spanish manufacturing firms. In this paper, we extend the previous analysis in three directions using a similar data set. First, we investigate additional economic performance differences between exporters and non‐exporters. Second, we measure TFP differences estimating production functions that control for unobserved heterogeneity and simultaneity bias. Third, we explore the self‐selection and learning‐by‐exporting hypothesis as explanations for the greater performance of exporters. With respect to the results, we confirm that many indicators of economic performance such as productivity, size, wages and innovation are greater in exporting firms. Furthermore, TFP differences between exporters and non‐exporters estimated with parametric methods are remarkably similar to those estimated using index numbers. Finally, performance differences and transition patterns between the export market and the domestic market indicate higher performance for entering exporters with respect to non‐exporters at the moment of entry. We find evidence of selection in the entry and the exit side of the export market. One of the basic results that we obtain indicates that after controlling for self‐selection, the productivity growth of entering exporters does not significantly change with respect to non‐exporters. As the evidence we find indicates no systematic changes in performance between non‐exporters and exporters after entry takes place, we do not confirm the learning‐by‐exporting hypothesis.  相似文献

In the field of territorial economic growth, it is possible to identify important characteristics in the entrepreneurial structure, such as the structure of the size of firms, main activity sectors, or the degree of innovation. However, other lesser known characteristics are important also, such as functional dependency, which considers the relationship between small and medium enterprises (SMEs), and suppliers and clients belonging to any territorial field or productive dependency, which considers the level of concentration in terms of buying and selling in connection with the main suppliers and clients, respectively. In order to empirically contrast the importance of these entrepreneurial characteristics and try to relate them with territorial economic growth, a sample of 400 enterprises in the province of Seville (Spain) is used.   相似文献

Comparability of statistical data between countries is a major objective for international statistical organisations such as EUROSTAT. The convergence criteria set down in the Maastricht Treaty explicitly require comparable consumer price indices in the European Union. We present an empirical analysis, largely based on simulations with Swedish and Finnish CPI data, of various potential sources of non-comparability, conceptual as well as technical ones.  相似文献

Despite extensive research on corporate responsibility, little research exists on how the inter‐organizational processes of defining corporate responsibility develop. In this paper, we present a framework based on actor‐network theory (ANT) for analysing these processes. The developed framework is illustrated in a study of the redefinition of Swedish garment retailers' responsibilities for workers' rights at suppliers' factories between 1996 and 2004. We show that definition processes can be characterized as battles for the right to interpretation, and that traditionally non‐dominant actors can, at least temporarily, win these battles and dictate the development of the processes for defining corporate responsibility. We also show that definition processes can take an exclusionary form prohibiting certain actors from participating. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.  相似文献

This paper presents the results of empirical research on the use of time‐based postponement in a supply chain context using data collected from two manufacturers, a distributor, and a retailer. The analysis shows that implementing postponement at the firm level can result in the supply chain carrying more inventory. In order to achieve its full potential, postponement needs to be implemented across organizations in the supply chain.  相似文献

This paper revisits Fama and French [Fama, Eugene F., French, Kenneth R., (1993) Common risk factors in the returns on stock and bonds. Journal of Financial Economics 33 (1), 3–56] and Carhart [Carhart, Mark M., 1997. On persistence in mutual fund performance. Journal of Finance 52 (1), 57–82] multifactor model taking into account the possibility of errors-in-variables. In their well known paper, Fama and French [Fama, Eugene F., French, Kenneth R., 1997. Industry costs of equity. Journal of Financial Economic 43 (2), 153–193] concluded that estimates of the cost of equity for the three-factor model of FF (1993) were imprecise. We argue that this imprecision is even more severe because of the pervasive effects of measurement errors. We propose Dagenais and Dagenais [Dagenais, Marcel G., Dagenais, Denyse L., 1997. Higher moment estimators for linear regression models with errors in the variables. Journal of Econometrics 76 (1–2), 193–221] higher moments estimator as a solution. Our results show that estimates of the cost of equity obtained with Dagenais and Dagenais estimator differ sharply from popular OLS estimates and shed a new light on performance attribution and abnormal performance (α). Adapting the Generalized Treynor Ratio, recently developed by Hübner [Hübner, Georges, 2005. The generalized treynor ratio. Review of Finance 9 (3), 415–435], we show that the performance of managed portfolios with multi-index models should be revisited in presence of errors-in-variables.  相似文献

Fixed effects estimators of nonlinear panel models can be severely biased due to the incidental parameters problem. In this paper, I characterize the leading term of a large-T expansion of the bias of the MLE and estimators of average marginal effects in parametric fixed effects panel binary choice models. For probit index coefficients, the former term is proportional to the true value of the coefficients being estimated. This result allows me to derive a lower bound for the bias of the MLE. I then show that the resulting fixed effects estimates of ratios of coefficients and average marginal effects exhibit no bias in the absence of heterogeneity and negligible bias for a wide variety of distributions of regressors and individual effects in the presence of heterogeneity. I subsequently propose new bias-corrected estimators of index coefficients and marginal effects with improved finite sample properties for linear and nonlinear models with predetermined regressors.  相似文献

This paper studies the effect of sovereign risk on capital flows from rich to poor nations in the context of a two-country model, where Foreign Direct Investment (FDI) creates positive externalities in domestic production. We show that if externalities are large, a developing country never expropriates foreign assets, and behaves as under perfect enforcement of foreigners' property rights, jumping to the steady state in one period. If externalities are absent, a developing country always expropriates foreign assets and, then, there are no capital flows in equilibrium, as occurs in autarky. If externalities are of a medium size, our model can account for scarce capital flows from rich to poor nations, as well as other key features of the data, such as rising-over-time patterns of foreign capital and FDI in developing countries. In addition, the model offers an economic rationale for the FDI restrictions observed across nations.  相似文献

Using a spatial econometric perspective, the speed of convergence for a sample of 163 regions of the European Union (EU) over the period 1981–1996 is estimated. For this purpose, we use a specification strategy which allows an explicit modeling of both spatial heterogeneity and spatial autocorrelation found in the analyzed sample. The estimated final model combines groupwise heterocedasticity, the identification of two spatial regimes and spatial dependence. Our results show how an appropriate consideration of the role of spatial effects can shed new insights into the European convergence process. We find that regions in the EU cohesion-fund countries (Ireland, Greece, Portugal and Spain) are converging separately from the rest of regions of the EU. Our estimations indicate that over the analyzed period, there was a faster conditional convergence in relative income levels of the regions belonging to Cohesion countries (5.3%) than in the rest of the regions of the EU (3.3%). Therefore, our results contrast with other evidence that points to the fact that the convergence process in Europe has weakened or even has stopped at the beginning of the 1980s. Moreover, our work shows clear evidence of separate spatial convergence clubs among EU regions.  相似文献

In many countries, regional income inequality has followed an inverted U‐shaped curve, growing during industrialization and market integration and declining thereafter. By contrast, Sweden's regional inequality dropped from 1860 to 1980 and did not exhibit this U‐shaped pattern. Accordingly, today's regional income inequality in Sweden is lower than in other European countries. We note that the prime mover behind the long‐run reduction in regional income differentials was structural change, whereas neoclassical and technological forces played a relatively less important role. However, this process of regional income convergence can be divided into three major periods. During the first period (1860–1940), the unrestricted action of market forces, particularly the expansion of markets and high rates of internal and international migration, led to the compression of regional income differentials. During the next period (1940–80), regional convergence was even more intense. In this period, institutional arrangements favoured the reduction of productivity differentials across industries and successive governments aided the reallocation of the workforce from declining to thriving regions and economic sectors. During the last period (1980–2000), when regional incomes diverged, internal migration and structural change slowed. Furthermore, the development of knowledge‐intensive service industries favoured economic growth in the main metropolitan areas.  相似文献
