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 evolution of a technological system: the case of CNC machine tools in Korea

Focusing on a product, this paper reconstructs the concept of technological systems first introduced by Carlsson and Stankiewicz (1991) in this Journal. Based on the model, we analyze the evolution process and performance of Korea's technological system for computer numerically controlled (CNC) machine tools as a catching-up case. The study shows that the length of 'learning period' for the system was substantial, even in a catching-up case. Especially, in the Korean case, the government played a 'macro-entrepreneurial' role in the molding of the technological system by giving legitimacy to the system, by mobilizing a nation-specific industrial organization of Chaebol system, and by enhancing the academia-industry-research institution links.JEL Classification: L52, L61, O30We thank two anonymous referees for very helpful comments and suggestions.Correspondence to: B.

On the vulnerability of the oil and gas industry to oil price changes

Previous studies of oil-price economic activity relationships are dominated by macro-level examination of price effects. This study examines the effect of shocks in oil price and its volatility on the oil and gas extraction industry using a Vector Auto-Regressive (VAR) approach. The results show that, in the short-run, positive price and volatility shocks lead to significant increases in oil and gas activities. However, in the long-run, the industry behaves much like the rest of the U.S. economy—price and volatility shocks produce small or insignificant effects. An earlier version of this paper was presented at the 22 ^nd Annual North American Conference of the U.S.A. Energy Economics/International Association of Energy Economics Conference, Vancouver, British Columbia. The authors acknowledge the editorial assistance of Versa Stickle.     

Aggregating Capacity-Limiting Separable Inputs

The concept of separability is closely related to aggregation. Previous studies on separability are important mainly for theoretical contributions, not for empirical results. This paper provides a theoretical justification for using the maximum capacity of a subset of inputs as an aggregate index in empirical settings. The method is demonstrated with two examples, aggregating inputs within a firm and across firms.     

Price convergence among Indian cities: A cointegration approach

Price dynamics in Indian cities were examined using cointegration analysis. We identified and calculated a common trend for prices in 25 major cities in India. Impulse response functions were obtained to calculate the rates of convergence to the prices and we found that the half-life of any shock is very small for Indian cities. Although a close to 3-month half-life seems too fast, there is some indication in the literature that half-life can be much smaller than the conventional rates of 3–5 years. We have calculated half-life using the panel unit root method, and found that estimates of half-life from cointegration analysis provide a faster convergence rate than estimates using the panel unit root method. We also analyzed how shock can be transmitted from one city to another and found no systematic behavior of transmission from one city to another.     

Inference of Seasonal Cointegration: Gaussian Reduced Rank Estimation and Tests for Various Types of Cointegration*

An extension of Gaussian reduced rank estimation of Ahn and Reinsel (Journal of Econometrics, Vol. 62, pp. 317–350, 1994) to seasonal periods other than four is presented. Simple adjustments for estimation that are necessary because of complex‐valued seasonal unit roots are presented in detail and the asymptotic distribution of the estimators that takes the same form as that in Ahn and Reinsel (1994) is derived. Tests for contemporaneous cointegration and common polynomial cointegrating vectors (PCIVs) for different seasonal unit roots are presented. Finite sample properties are briefly examined through a small Monte Carlo simulation study and a numerical example is presented to illustrate the methods.     

INTEREST RATE CHANGES AND COMMON STOCK RETURNS OF FINANCIAL INSTITUTIONS: REVISITED

In this paper the interest rate sensitivity of common stock returns of financial firms is re-examined. Considered here are (1) current, anticipated, and unanticipated changes in interest rates; (2) depository and nondepository firms; and (3) three different-maturity interest rate indices. Results lend strong support for a negative effect of both current and unanticipated interest rate changes. Although some exceptions are observed, stock returns of most subsectors of both financial and nonfinancial firms are not sensitive to anticipated interest rate changes. The findings of this study are robust to the choice of a particular model of interest rate expectations.     

Dollarization,Seigniorage, and Prices: The Case of North Korea

This study employs a general equilibrium monetary search model to examine the effects of the recent dollarization in North Korea on seigniorage and prices. Maximum seigniorage is generated at a high rate of money growth when dollarization is mild. However, under a high degree of dollarization seigniorage declines sharply when the money growth rate is high. Accordingly, seigniorage can be increased by de-dollarizing the economy through lowering the money growth rate. This finding implies that the post-2013 price stabilization may be a result of the restriction on printing of money with the aim of increasing seigniorage. This finding also recognizes that the North Korean authorities have little room for maneuver on monetary policy under the conditions of widespread dollarization.     

Strategic Delegation in a Multiproduct Mixed Industry

We examine strategic delegation in a multiproduct mixed duopoly with nonprofit organization (NPO) and for‐profit organization (FPO). We will demonstrate that the nonprofitable mission service can reduce both the interest conflicts between the NPO and FPO owners and those between the NPO owner and self‐benefited manager. The profit orientation in the compensation schemes will vary with different relative costs. Although the NPO owner may have a different objective from the FPO owner, they all end up having their managers raise their prices and reducing competition in the profitable market. Moreover, as the regulated price of mission service increases, both firms will charge more for their profitable services, but the owner of NPO could still overcompensate her or his manager, when the indirect impact on increasing the conflict of interest is higher than the direct impact on price.

The Effects of Personnel Reform Systems on Georgia State Employees' Attitudes

Abstract

In order to maximize the value of human resources, today's reformers have abandoned traditional merit systems, calling instead for public personnel management systems based on a set of new principles known as managerialism. The study at hand, conceived within a principal–agent theoretical framework and using a confirmatory factor analysis (CFA), a hierarchical regression model and a structural equation model (SEM), probed four personnel reform effects in the state of Georgia: (1) a monetary incentive system (i.e. a merit pay system); (2) a performance monitoring system (i.e. a performance appraisal system); (3) a knowledge incentive system (i.e. a training and development system); and (3) a discretionary controlling system (i.e. an at-will system). The research findings indicate that all four personnel reform systems are directly and indirectly associated with organizational consequences. Among these effects, discretionary controlling and performance monitoring systems are most salient and are most effective at enhancing the level of an agent's work motivation and job satisfaction as well as decreasing their turnover intentions. Implications and limitations of this research are also discussed.
