In this paper we use a micro panel data set of Spanish manufacturing firms to measure the contributions of continuing firms and turnover to total factor productivity growth over the period 1990–1997. The paper proposes an approach to the decomposition of productivity growth that is based on the estimation of productivity distributions. We characterize the dynamics of productivity distributions defining counterfactual distributions and using non-parametric methods. The results we obtain indicate that incumbent firms are the main factor contributing to the change in the productivity distribution. Net entry contributes positively to TFP growth. Finally, changes in the relative weights of incumbent, entering and exiting firms produce a counter-cyclical movement of productivity.  相似文献

Since the initial studies of derecognition, many articles have focused on the issue, by and large pointing to a slow increase in derecognition. However, a small number have indicated it is actually much larger. This paper shows that derecognition is even greater than these suggest and that its nature has changed. The paper looks at the contexts of this rise but argues that derecognition should not yet be seen as a major problem facing the unions.  相似文献

Probability of informed trading (PIN) models characterize trading with certain types of information through a tree structure. Different tree structures with different numbers of groups for market participants have been proposed, with no clear, consistent tree used in the literature. One of the main causes of this inconsistency is that these trees are artificially proposed through a bottom-up approach rather than implied by actual market data. Therefore, in this paper, we propose a method that infers a tree structure directly from empirical data. More precisely, we use hierarchical clustering to construct a tree for each individual firm and then infer an aggregate tree through a voting mechanism. We test this method on US data from January 2002 for 7608 companies, which results in a tree with two layers and four groups. The characteristics of the resulting aggregate tree are between those of several proposed tree structures in the literature, demonstrating that these proposed trees all reflect only part of the market, and one should consider the proposed empirically driven method when seeking a tree representing the whole market.

We analyze the effects of taxation in two-sided matching markets where agents have heterogeneous preferences over potential partners. Our model provides a continuous link between models of matching with and without transfers. Taxes generate inefficiency on the allocative margin, by changing who matches with whom. This allocative inefficiency can be nonmonotonic, but is weakly increasing in the tax rate under linear taxation if each worker has negative nonpecuniary utility of working. We adapt existing econometric methods for markets without taxes to our setting, and estimate preferences in the college-coach football market. We show through simulations that standard methods inaccurately measure deadweight loss.  相似文献

Places have started to adapt commercial branding tactics. But how do stakeholders perceive such practices? Drawing on survey data from French residents, we analyse the advertising legitimacy of a place brand and its influence on the effectiveness of marketing communications in the context of region branding. The results confirm that advertising legitimacy mediates the relationship between exposure to an advertisement and its efficiency. The place brand is more legitimate when advertisements target firms, residents or tourists than when they promote local products through co-branding. We highlight a new expression of democratic legitimacy: a process adapted to hybrid (public–private) organizations.  相似文献

Social network marketing has risen to the fore as an innovative and cost effective method of reaching a target audience. However, owing to the recentness of this marketing technique, there is little scholarly research in this area, especially in emerging markets. This study considered the impact of interactivity and media richness on brand attitude and brand image in the South African beer market. It also tested whether brand involvement has a moderating effect in this regard. The empirical work was conducted through an electronic survey of Facebook fan page users. The results revealed that interactivity had a positive effect on brand attitude, whilst media richness did not. Brand involvement, tested for a moderating effect on the above relationships, was not found to be significant. As expected, brand attitude was found to be strongly linked to brand image in this context. The findings stress the importance of bidirectional communication in favor of media rich design. This suggests that marketers of beer would be well advised to engage with customers on fan pages in routinely responding to their comments and allowing them to upload suitable content. If consumers feel that they have ‘ownership’ of these pages and are able to have a positive influence on brand evolution, fan pages are likely to yield positive results in social media campaigns.  相似文献

Consumers use affective evaluations of past hedonic experiences in their future decision-making. However, past evaluations such as how enjoyable the experience was may be hard to retrieve, and consumers tend to recall what they did (i.e. the constituent activities of the prior experience) in order to reconstruct them. It is proposed here that recalling these constituent activities in a packed versus unpacked fashion will distort both the reconstruction process and its outcome. Results from two experiments show that mental unpacking interacted with experience enjoyment to alter past evaluations in two ways: if the enjoyment of the experience was high, unpacked recalls increased remembered enjoyment, but unpacking decreased remembered enjoyment if the experience enjoyment was low. Finally, mediation analysis indicated that the unpacking by enjoyment interaction distorted future preferences through the mediating role of remembered enjoyment.  相似文献
