Managerial decision making in customer management: adaptive, fast and frugal?

While customer management has become a top priority for practitioners and academics, little is known about how managers actually make customer management decisions. Our study addresses this gap and uses the adaptive decision maker as well as the fast and frugal heuristics frameworks to gain a better understanding of managerial decision making. Using the process-tracing tool MouselabWEB, we presented sales managers in retail banking with three typical customer management prediction tasks. The results show that a majority of managers in this study are adaptive in their decision making and that some managers use fast and frugal heuristics. Usage of adaptive decision making seems to be mainly driven by low objective task difficulty, the use of fast and frugal heuristics by experience. While adaptive decision making does not impact predictive accuracy, usage of fast and frugal heuristics is associated with proportionally greater use of high predictive quality cues and a significant increase in accuracy. Hence, the existing skepticism concerning heuristics should be questioned.     

Changing factor market conditions in South Africa: The capital market – a sectoral description of the period 1970–97

This article explores changing conditions in South African real capital markets. Noteworthy is the evidence of strong restructuring in this market during the 1990s. Whereas the 1970s and 1980s showed the best investment performance among primary commodity sectors and sectors with strong parastatal involvement, the highest investment rates of the 1990s have been associated with the manufacturing industry. We show that the real user cost of capital and capital productitivity contribute plausible determinants of investment rates in South Africa. The extent to which market forces are allowed to bring in line marginal cost and marginal return on capital appears to influence the sustainability of investment.     

The Success of the Nordic Countries as a Blueprint for Small Open Economies

To retain their leading position, the Nordics must invest in developing more sophisticated products than competing economies like Turkey. This applies to all complex economies, but constitutes a greater challenge to the Nordic countries with their comparatively small populations.     

International strategy’s effects on retailers’ local implementation and performance

Retailers dynamically expand abroad and strategically seek local performance because their business is local. However, knowledge of the contribution of retail firms’ international strategies to subsidiaries’ local performance is limited. Based on the prominent I/R strategy framework, the authors conceptualize integration/responsiveness as the transfer/local generation of firm-specific advantages and analyze (direct and indirect) paths of varying degrees of I/R via local implementation decisions to performance. Because retailers’ firm-specific advantages have a limited geographic reach, different successful paths are expected in close and distant countries. Empirically, a survey based on face-to-face-interviews with 126 retail CEOs and expansion managers, partial least squares structural equation modelling and bootstrapping-based mediation analyses were conducted. The results reveal only indirect paths of international strategy to local performance through local standardization/centralization. Unique insights into the paths of firm? strategy to subsidiary performance emerge, such as important tradeoffs between superior paths in close countries.     

A SHORT NOTE ON SECOND-ORDER STOCHASTIC DOMINANCE PRESERVING COHERENT RISK MEASURES

We improve results on law invariant coherent risk measures satisfying the Fatou property due to Kusuoka (2001; Adv. Math. Econ . 3, 83–95) by considering risk measures which are in addition second order stochastic dominance preserving. In particular, we derive a representation result for such risk measures.     

Wärmecontracting in der deutschen Wohnungswirtschaft: Instrumente für eine angemessene Regulierung

German residential leases and their associated fringe costs such as heating are subject to strict regulations. The Tenancy law regulates, for instance, which components of the total costs of heating tenants have to bear and to what degree lessors can amortise the costs for modernizing the heating system. Unfortunately these regulations provide only low incentives for modernization, so that many heating systems in operation are technically obsolescent.Contracting describes a service contract, in which a Contractor plans, builds up and also operates a new heating system. This service-form has been successfully established in many other economic sectors so far. Despite the great micro- and macroeconomic advantages that Contracting offers over self-administered modernizing, it does not yet prevail in the German housing market. Thus, deregulation seems to be indispensable in this sector. However, the analysis in this article on the basis of the New Institutional Economics shows that an unrestricted opening of the market is not reasonable. In fact a suitable level of regulation must be found. Therefore, this article identifies several effective instruments from an economic point of view.     

Optimal tax policy when firms are internationally mobile

The standard tax theory result that investment should not be distorted is based on the assumption that profits are locally bound. In this paper, we analyze the optimal tax policy in a model where firms are internationally mobile. We show that the optimal policy response to increasing firm mobility may be taxation, subsidization, or non-distortion of the marginal investment, depending on whether the mobile firms are more or less profitable than the average firm in the economy. Our findings may contribute to understanding recent tax policy developments in many OECD countries.     

On the existence of shadow prices

For utility maximization problems under proportional transaction costs, it has been observed that the original market with transaction costs can sometimes be replaced by a frictionless shadow market that yields the same optimal strategy and utility. However, the question of whether or not this indeed holds in generality has remained elusive so far. In this paper, we present a counterexample which shows that shadow prices may fail to exist. On the other hand, we prove that short selling constraints are a sufficient condition to warrant their existence, even in very general multi-currency market models with possibly discontinuous bid–ask spreads.
