出口活动、贸易强度与制造业行业生产率——来自我国中部地区的经验数据

文章以我国中部6省制造业的21个行业为研究对象,采用DEA数据包络分析法科学测度了中部6省制造业行业最近十年的全要素生产率,再结合静态与动态面板模型对出口活动、强度与制造业企业生产率的关系进行了实证研究。结果表明中部地区的出口强度与整体制造业的生产率具有正相关,促进了中部地区发展;而出口活动对制造业生产率的促进作用主要是集中在高技术行业。对于传统行业,出口活动反而降低了制造业生产率。

Different recipes for success in business relationships

Companies need to manage business relationships successfully in order to stay competitive. Drawing on configurational logic, this study shows that companies can improve their relationship performance through leveraging the structure of their business relationships. However, relationship structures must align with the company's business strategy. To date, research has focused on individual characteristics of business relationships, but little is known about relational configurations, namely the interplay between different business relationship characteristics on the one hand, and the firm's underlying business strategy on the other. We apply Hoffmann's (2007) strategy typology, namely shaping, adapting, and stabilization strategy types, to operationalize different business strategies. Drawing on a sample of 658 business service companies and employing fuzzy set qualitative comparative analysis (fsQCA), this study confirms the existence of different recipes for success, that is, multiple equifinal configurations leading to relationship performance. For each of the three business strategies, different combinations of relationship characteristics are successful, each encompassing a distinct configuration of core and periphery conditions. While firms following an adapting strategy should stress behavioral commitment above all other relationship characteristics, the two remaining business strategies instead rely predominantly on different factors such as trust and communication. This study contributes to business marketing theory and practice by highlighting different ways to develop business relationships successfully.

Gibrat's Law: Are the Services Different?

Several noted surveys on intra-industry dynamics have reached the conclusion from a large body of evidence that Gibrat's Law does not hold. However, almost all of these studies have been based on manufacturing or large scale services such as banking and insurance industries. There are compelling reasons to doubt whether these findings hold for small scale services such as the hospitality industries. In this paper we examine whether the basic tenet underlying Gibrat's Law– that growth rates are independent of firm size – can be rejected for the services as it has been for manufacturing. Based on a large sample of Dutch firms in the hospitality industries the evidence suggests that in most cases growth rates are independent of firm size. Validation of Gibrat's Law in some sub-sectors of the small scale services suggests that the dynamics of industrial organization for services may not simply mirror that for manufacturing. The present paper includes a survey of nearly 60 empirical studies on firm growth rates.     

Wage Cyclicality Under Different Regimes of Industrial Relations

We analyze the effect of collective wage agreements and of works councils on the cyclicality of real wages. Using employer–employee data for western Germany (1995–2004), we find that wage adjustments to positive and negative shocks are generally not symmetric. Wage growth increases in all industrial relations regimes when unemployment is falling, but this inverse relationship is weaker when unemployment is rising. Moreover, in plants with individual‐level bargaining, wages do not adjust at all to rising unemployment. Works councils increase wage growth only in firms covered by sectoral agreements, but they do not affect the cyclicality of wages.

A Different Look at Commercial Real Estate Returns

Commercial real estate makes up a relatively small percentage of most institutional portfolios, even though the existing literature has consistently reported attractive risk-return characteristics that would suggest much larger allocations. This discrepancy has been explained by a perceived lack of comparability between return series calculated for real estate and those calculated for other asset classes. Just as investors actively involved in the futures markets do not consider individual common stocks to be traded continuously, those active in the stock market do not consider real estate to be traded continuously. In both cases, adjustments to reported returns are necessary to achieve a degree of comparability. This study makes such adjustments, using sales data from properties that help comprise the National Council of Real Estate Investment Fiduciaries / Frank Russell Company (NCREIF/FRC) Index to generate a "transaction-driven" commercial real estate return series. Examination of the risk-return characteristics of this series shows that it is quite different from traditionally reported real estate return series and far more consistent with risk-return characteristics that have been reported for other asset classes.
