Ownership structure and board composition in a high ownership concentration context

Few articles have addressed the relation between the ownership structure and the composition of the boards. The results of the analysis performed on a sample of Spanish listed companies for the period 2004–2011, show that in markets where corporate ownership is highly concentrated, it is necessary to devote special attention to blockholders and to differentiate the figure of the independent directors from the group of outsiders. The results confirm a negative and decreasing relation between blockholders and the percentage of independents while insiders’ ownership is only significant if one looks at the percentage of outsiders as a whole, in which case it shows a U-shaped quadratic relation.     

Connecting external knowledge usage and firm performance: An empirical analysis

Prior research suggests that firms create breakthrough innovations by using external knowledge, but it also underscores the difficulties firms face in acquiring and applying external knowledge. In this paper, we combine these insights to examine the conditions under which external knowledge usage will either enhance or erode firm performance. In particular, we argue that high external knowledge usage has a negative effect on performance when firms enter multiple new product markets, but a positive effect on performance when firms using external knowledge have higher absorptive capacity. We find general support for our hypotheses, which we test using patent citation data from the global integrated circuit manufacturing industry. Our findings have important implications for managers of firms making strategic decisions about their firms’ product portfolios and the degree to which they use external knowledge.     

Standards, critical mass, and the formation of complex industries: A case study of the mobile Internet

This is one of the few papers to analyze multiple interface standards in a single industry and it finds that standard setting in such an industry is much more complex than those covered in the existing literature. In the mobile Internet, some of the interface standards initially required so-called integral design while others have been built on top of these “basic” interface standards. The former interface standards enable basic data connections between phones, services, and content while the latter ones connect the mobile phone with content and applications from other industries such as music, video, publishing, broadcasting, and payment. This paper shows that in connecting the mobile phone and other industries, each critical mass of phones, services, and content partly builds from previously created critical masses.     

企业生产组织形式的演化

企业管理思想的演变集中体现在具体的生产组织形式上。纵向一体化、横向一体化和供应链管理为三种依序发展的生产组织形式。这三种形式有其内在的关联和逻辑一致性。企业如果实施供应链管理,要持有理性的态度,特别是不能在供应链中充当核心作用的企业尤要谨慎决策。     

WHY DO EMERGING ECONOMIES BORROW SHORT TERM?

We argue that one reason why emerging economies borrow short term is that it is cheaper than borrowing long term. This is especially the case during crises, as during these episodes the relative cost of long‐term borrowing increases. We construct a unique database of sovereign bond prices, returns, and issuances at different maturities for 11 emerging economies from 1990 to 2009 and present a set of new stylized facts. On average, these countries pay a higher risk premium on long‐term than on short‐term bonds. During crises, the difference between the two risk premia increases and issuance shifts towards shorter maturities. To illustrate our argument, we present a simple model in which the maturity structure is the outcome of a risk‐sharing problem between an emerging economy subject to rollover crises and risk‐averse international investors.     

JEEA‐FBBVA LECTURE 2013: THE NEW EMPIRICAL ECONOMICS OF MANAGEMENT

Over the last decade the World Management Survey (WMS) has collected firm‐level management practices data across multiple sectors and countries. We developed the survey to try to explain the large and persistent total factor productivity (TFP) differences across firms and countries. This review paper discusses what has been learned empirically and theoretically from the WMS and other recent work on management practices. Our preliminary results suggest that about a quarter of cross‐country and within‐country TFP gaps can be accounted for by management practices. Management seems to matter both qualitatively and quantitatively for performance at the level of the firm and the nation. Competition, governance, human capital, and informational frictions help account for the variation in management. We make some suggestions for both policy and future research.     

LETTER GRADING GOVERNMENT EFFICIENCY

We mailed letters to non‐existent business addresses in 159 countries (10 per country), and measured whether they come back to the return address in the United States and how long it takes. About 60% of the letters were returned, taking over six months, on average. The results provide new objective indicators of government efficiency across countries, based on a simple and universal service, and allow us to shed light on its determinants. The evidence suggests that both technology and management quality influence government efficiency, just as they do that of the private sector.     

THE INTERNATIONAL DIMENSION OF PRODUCTIVITY AND DEMAND SHOCKS IN THE US ECONOMY

This paper analyzes the cross‐country effects of productivity and demand disturbances in the United States identified with sign restrictions based on standard theory. Productivity gains in US manufacturing increase US consumption and investment vis‐à‐vis foreign countries, resulting in a trade deficit and higher international prices of US goods, despite the rise in their supply. Financial adjustment works via a higher global value of US equities, real dollar appreciation, and an expansion of US gross foreign liabilities as well as assets. Positive demand shocks to US manufacturing also increase investment and cause a real dollar appreciation, but have limited effects on the trade balance and net foreign assets. Our findings emphasize the importance for macroeconomic interdependence of endogenous fluctuations in aggregate demand across countries in response to business cycle shocks.
