Differential effects of pre- and post-acquisition R&D expenditures on post-acquisition performance

Drawing from the behavioral theory of the firm and the resource-based view, we argue that different types of R&D (explorative and exploitative) and the timing of R&D investments (pre- and post-acquisitions) have differential effects on post-acquisition performance. By using a sample of 396 technology acquisitions, we find that pre-acquisition explorative and post-acquisition R&D expenditures are more beneficial for post-acquisition performance than are pre-acquisition exploitative and post-acquisition explorative R&D expenditures. Our results also show that firms investing in explorative R&D in the pre-acquisition stage and then exploitative R&D in the post-acquisition stage have better post-acquisition performance than firms that do otherwise.     

Market concentration and competition in OECD mobile telecommunications markets

This study analyses the progress of market concentration in OECD member states’ mobile telecommunications markets and evaluates the relationship between market concentration and performance. Using annual panel data from 24 OECD member states for the 1998–2011 period, the study estimates regression equations for market concentration, mobile prices and profits. The empirical results indicate that the more concentrated the mobile market, the higher the prices and profits, providing support for the market power hypothesis. If this hypothesis holds, then market concentration can be a useful indicator of market performance. On the other hand, the applicability of the hypothesis is unclear for the second half of the sample period. The results provide evidence that regulatory policies influence the structure and performance of mobile markets.     

Declining first-mover advantage in mobile telecommunications markets

First-mover advantage may be more remarkable in the inherently oligopolistic mobile telecommunications market. This study evaluates the impact of market experience and competition on market share and profitability in mobile markets. Specifically, the study estimates regression equations for market share and earnings before interest, tax, depreciation, and amortization (EBITDA) service margin as a proxy for profitability, relying on a panel of mobile network operator (MNO) data from 27 Organisation for Economic Co-operation and Development member states for the period 1998–2009. The empirical results demonstrate that market experience (relative time in the market) exerted a clearly positive effect on the market share and the EBITDA service margin for MNOs. On the other hand, this first-mover advantage declines over time with accumulated competition experience, especially in the latter half of the 2000s.

The Effects of Changes in Property Tax Rates and School Spending on Residential and Business Property Value Growth

In this article, we examine the effects of changes in property tax rates and school spending on residential and business property value growth in southeast Michigan. We use panel data for 152 communities in the five counties surrounding Detroit between the years 1983 and 2002, a period during which state government mandated major changes to school finance. Using the mandated changes to identify causality, we find that: (1) residential property values are more responsive to school spending changes than property tax rate changes; (2) business property values are more responsive to tax rate changes than school spending changes; and (3) business property values are more sensitive to changes in tax rates as compared to residential property. We also examine tax competition effects on property value growth, showing that tax competition plays an important role in property value growth in the southeast Michigan region.     

Improving collaboration between large and small-medium enterprises in automobile production

ABSTRACT

Inter-organisational collaboration is important for achieving qualitative and quantitative performance improvement in the global competitive environment. In particular, the extent of collaboration between the mother company and its suppliers is important for the profitability and sustainability of a company in the automobile industry, which is carried out using a customisation and order production system. As a result of the empirical analysis in this study, the collaborative information sharing cycle is shortened and the collaborative information sharing scope is widened. Therefore, the level of collaboration is improved by constructing an IT collaboration system.     

Maximum entropy autoregressive conditional heteroskedasticity model

In many applications, it has been found that the autoregressive conditional heteroskedasticity (ARCH) model under the conditional normal or Student’s t distributions are not general enough to account for the excess kurtosis in the data. Moreover, asymmetry in the financial data is rarely modeled in a systematic way. In this paper, we suggest a general density function based on the maximum entropy (ME) approach that takes account of asymmetry, excess kurtosis and also of high peakedness. The ME principle is based on the efficient use of available information, and as is well known, many of the standard family of distributions can be derived from the ME approach. We demonstrate how we can extract information functional from the data in the form of moment functions. We also propose a test procedure for selecting appropriate moment functions. Our procedure is illustrated with an application to the NYSE stock returns. The empirical results reveal that the ME approach with a fewer moment functions leads to a model that captures the stylized facts quite effectively.     

Food Security and Agricultural Protection in South Korea

South Korea has been pursuing food self-sufficiency using high tariffs and high administrative prices in key agricultural and food markets. Using a dual approach to trade and trade restrictiveness indices, we analyze the impact of these market distortions on welfare and trade volume. Then, we compute second-best distortions, which minimize the welfare cost of meeting observed levels of self-sufficiency and production. We rationalize these second-best distortions to what could be claimed as legitimate protection under a "food security" (FS) box in World Trade Organization (WTO) negotiations. FS-box protection is sensitive to changes in the definition and the extent of the FS objectives. We show that FS via production targets and reliance on imports would be more palatable to consumers and trade partners, while preserving income transfer to the farm sector.     

Unpacking the relationship between empowering leadership and service-oriented citizenship behaviors: a multilevel approach

Drawing on empowerment theory, this study examines the effect of empowering leadership on frontline employees’ service-oriented citizenship behaviors and the process by which this effect occurs. The authors conceptualize empowering leadership at two levels: individual level and group level. Using multi- and cross-level modeling based on multi-source data (frontline employees and their supervisors) from a national automobile dealership at two different time points, this study finds that group-level empowering leadership explains unique variance in service-oriented citizenship behaviors above and beyond what is explained by individual-level empowering leadership. Further, psychological empowerment and customer learning climate partially mediate the empowering leadership–service-oriented citizenship behaviors relationship at the individual and group levels, respectively. Finally, the results indicate that a climate for customer learning accentuates the positive effect of psychological empowerment on service-oriented citizenship behaviors. Theoretical and practical implications for improving frontline employee’s service-oriented citizenship behaviors are discussed along with directions for future research.
