How and when is dual trading irrelevant?

Within a general model of speculative trade, we derive the aggregate consequences of dual traders who process retail liquidity trades and trade on their own account. We prove that dual trading reduces total expected speculator profits unless speculators process all liquidity trade and trade with the same intensity on liquidity trade. In contrast, dual trading does not affect the information content of prices. We show how results generalize when we endogenize (a) speculator information via costly information acquisition about fundamentals or costly processing of liquidity trade, and (b) liquidity trader motives and welfare via endowment shocks.     

Breaking Up Old Marriages: The Political Process of Change and Continuity at Work

This article contends that political processes are essential dynamics in creating continuity and change in organizations. A central aim is to inform the debate on change in organizations by conceptualizing and exploring the interplay between actors' political rationales, organizational culture, and new management concepts. Attention is given to the introduction of technical-bureaucratic management concepts for Occupational Health and Safety and the environment through presenting a case study, where both managers' and shop-floor personnel's political behaviour can be examined. The findings illustrate how continuity rather than change often prevails through the existence of more stabilized patterns of politics. The establishment of shared systems of meaning, conceived as the social constitution of the company, is shown to be a central mechanism for the regulation of politics, explaining the selectivity of politics regarding issues, arenas, arguments and actors. In particular, the relative importance of shop-floor personnel's politicking is discussed, and it is shown how their way of politicking differs from the forms found in management. Consequently it is suggested, that studies of political processes, which seek to encompass these forms of politics would benefit from the insights gained in cultural studies.     

Information technology,transaction costs and the decision to 'make or buy'

Information and communication technology (ICT) has a wide ranging impact on business. One of the effects is on the 'make or buy decision'. This is analysed from the perspective of transactzon cost economm (TCE). On the one hand ICT reduces transaction costs by reducing search costs, by facilitating monitoring and control of performance and by yielding a greater flexibility of production, which reduces the transaction specificity of assets. These efiects, favour the decision to 'buy'. On the other hand, ICT reduces economies of scale, in some areas of production, which makes outside production i n a specializedfirm less attractive. Also, ICT may be used to impose switching costs between suppliers and buyers, thereby miszng transaction costs. But such ploys appear to be feasible only temporarily, with a pressure from users and competitors towards standardization and open systems. Thus the effects of ICT are diverse, but on the whole it tends to favour the option to contract out.     

Income Level and the Value of Non-Wage Employee Benefits

With continuing increases in the cost of medical insurance and other “fringe” benefits, payroll cost for monetary and non-monetary aspects of compensation is a significant factor for most organizations. While this is not a new phenomenon, relatively few studies in the empirical literature have examined the role of fringe benefits in employee compensation plans. Especially in under researched areas, it is imperative that researchers utilize ideas and theories from other disciplines to further our knowledge. Accordingly, this paper borrows the concept of elasticity from the economic literature to help explain and understand employee perceptions of two of the most common, costly, and important benefits—medical insurance and retirement plans. Specifically, the relationship between the current income of employees is analyzed in relation to employee perceptions of the value and importance of benefits. Results suggest that employees do not value medical insurance and retirement plans in the same manner. This result is interpreted in terms of the change in the marginal utility of the specific benefit.     

Market Quality around Macroeconomic News Announcements: Evidence from the US and Canadian Markets

We investigate changes in market quality in the US and Canada during macroeconomic news announcements. We measure market quality in terms of returns dependence, the cost of trading, and pricing errors. Using a sample of cross‐listed stocks and macroeconomic news from both countries, we document that market quality is generally higher in the US than in Canada. The pattern of intraday serial dependence in returns reveals that it takes investors about 5 min less to react to order imbalances in the US than in Canada. We further observe that, around announcement periods, transaction costs increase more in Canada than in the US, suggesting that the US market offers better liquidity. More information is also incorporated into the US market. These results support the view that the US is a prime target for cross‐listing, and are robust to different types of assets and time specifications.     

An evaluation of yardstick regulation for European airports

The European airport industry is subject to various forms of economic regulation and there is debate as to which of the systems provides the best incentives for allocative and productive efficiency. This paper deals with the applicability of benchmarking as a regulatory tool for airports. This form of regulation aims at evaluating the cost level of a firm by comparing it to the mean marginal cost structure of all other firms in the market. The paper investigates the difficulties arising from airport benchmarking as well as the benefits that might be derived from it by drawing lessons from benchmark regulation in other industries and the few cases where it has been applied to airports. In particular, it assesses whether yardstick regulation is a feasible alternative to the existing forms of economic regulation or whether yardsticks are more useful for internal management purposes.     

Quantitative Restrictions in the Presence of Cost-Based Informational Asymmetries

This study introduces a cost-based informational asymmetry into a two-period model where a domestic (incumbent) firm's behavior in the first period affects the entry decision of a foreign firm in the second period. The effects of import quota policy within this environment are examined and compared to the standard, full-information effects. When quota quantities are set exogenously, the standard effects of quota policy may be significantly altered depending on whether or not policy induces the domestic firm to signal cost structure. For example, higher quotas may discourage foreign entry because of the induced signaling effects of quota policy.
