The pattern of changes in the long-term development of establishment size

Hypotheses and analyses dealing with the expansion of small businesses are usually carried out over relatively short periods of time. The patterns drawn from these examinations, e.g., on the question of specific differences in the growth of size, are usually influenced by configurations of the overall economy and limit the realization of regular processes to the phases they are based upon. A second disadvantage lies in most cases in the fact that data sources are used for the empirical analyses that do not cover the economic system as a whole nor for all sizes of establishments. This study attempts to present the development of the sizes of establishments in Germany over a period of more than one hundred years (1882 to 1987) and thus avoids the narrow perspective of previous examinations. It becomes evident that this development does not take a continuous course; instead, it follows a wave pattern. Since this discontinuous development pattern is common to almost all sectors, it appears to be a general phenomenon. This study reveals that the small establishments with more than five employees, contrary to most theoretical assumptions, are of utmost importance even when considered over a long period of time. The growth of small establishments in recent years, observable in all sectors, may not be a unique phenomenon; however, in view of an overall growth of employment and the simultaneous shrinking of large establishments, it occurs under a new constellation.     

Commitment and coordination in a dynamic game model of international economic policy-making

In this paper, we consider a dynamic game model of two identical countries. Policy-makers of both countries have quadratic intertemporal objective functions and want to stabilize domestic output, domestic inflation, and the real rate of exchange. We present different analytical and numerical solutions for this policy game. Noncooperative open-loop equilibria are interpreted as requiring unilateral commitment and policy-makers' credibility. Potential gains from cooperation are present, as the noncooperative equilibrium solutions are not Pareto-optimal. Under an information pattern that admits memory strategies, the possibility of obtaining cooperative results without coordination and commitment arises.

Strategic step-by-step negotiation

We analyze a specific type of negotiation process where parties proceed in stages taking into consideration that negotiation may end prematurely with an inefficient agreement. Parties negotiate only one increasing pie, thereby avoiding inefficiencies which are typical for issue-by-issue negotiations. For ann-stage game, we prove the existence of a unique subgame-perfect equilibrium. We then show that step-by-step negotiation can only improve players' expected payoffs if negotiation in stages reduces the difference between their equilibrium offers. For this to occur, however, the risk of negotiation must be affected by the agenda of the bargaining problem.     

Stock Splits in Switzerland: To Signal or Not to Signal?

In Switzerland, the existence of a mandatory minimum par value inhibited many companies from splitting their stocks as they already traded at their minimum par value. These Swiss companies could split their stocks only after the legal minimum par value was lowered in July 1992 and again in May 2001. These two events provide rare opportunities to distinguish between stock splits that signal a permanent increase in stock price and splits that are merely a reaction to a regulatory change and thus have other motives. The significant return differences between the two samples are in line with the hypothesis that splits are a means to send positive signals to the stock market. Furthermore, while trading volumes remained largely unaffected after stock splits, relative tick sizes generally increased after a stock split, and bid-ask spreads often increased after a stock split.     

Memory Effects of Different Relational Links between Brands and Sponsored Events

Sport sponsorship is an important marketing communication tool, and stakes in sponsorship deals are high. Therefore, sponsors strive to ensure that their investments are effective and protected from competitors—that is, ambusher marketers’ attacks. Still, little is known about how ambush marketing affects sponsor identification and misidentification of ambushers as sponsors. This study investigates levels of sponsor and ambusher identification in three experimental settings, controlling for the presence/absence of an ambusher, communication modality, and response formats. A field study in the context of a large sports event demonstrates the external validity of the findings. The results provide evidence of a nondestructive interference of ambush marketing, indicating that ambush marketing does not necessarily harm sponsor identification. Misidentification of nonsponsors as sponsors occurs because of the indirect link established between the event and the company through ambush marketing, but not as a consequence of other communication activities by a competitor with no link to the event. Finally, a combined sponsor–ambusher perspective indicates that sponsors do not necessarily have a consistent “official sponsor” advantage over ambushers. Findings are discussed with emphasis on implications for sponsors, ambushers, and marketing researchers.     

Bounded Rationality Modeling

This paper deals with bounded rationality as a way to describe behavior and focuses on the question of how to build such boundedly rational models. The first part is a discussion of the reasons why such models are needed and on the situations in which they can be regarded as more particularly useful. The second part examines three strategies of research towards bounded rationality modeling which have emerged in the last ten years and weights them. The concluding remarks offer a first link between the respective typologies of strategies and of situations and calls for additional experimental work by marketing scientists and economists together.     

Macroeconomic impacts of European union membership of central and eastern European economies

This paper examines the impact of an eastern enlargement of the European Union. This is modeled as an increase in total factor productivity and a decrease in the risk premium for the central and eastern European countries (CEECs). In particular, a multicountry model of the world economy is used to assess the direct effects and spillovers of these changes. Inflation targeting for the euro zone by the European Central Bank and alternative scenarios with respect to fiscal policy behavior in the CEECs are considered. According to these simulations, productivity effects are stronger than risk premium effects, and spillovers are small.
