Consumption paths under prospect utility in an optimal growth model

This paper studies the Cass-Koopmans-Ramsey model of optimal economic growth in the presence of loss aversion and habit formation. The representative agent's preferences for consumption can be gradually varied between the standard constant intertemporal elasticity of substitution (CIES) case and Kahneman and Tversky's prospect utility. We find that the transitional dynamics of optimal consumption paths differ distinctly from the standard model, in particular consumption smoothing is more pronounced. We also show that prospect utility can cause the economy to remain in a steady state with low consumption and low capital.     

Production technologies in stochastic continuous time models

Properties of dynamic stochastic general equilibrium models can be revealed by either using numerical solutions or qualitative analysis. Very precise and intuition-building results are obtained by working with models which provide closed-form solutions. Closed-form solutions are known for a large class of models some of which, however, have some undesirable features such as potentially negative output. This paper offers closed-form solutions for models which are just as tractable but do not suffer from these shortcomings.     

Major problems of tourism growth in developing countries

The following paper is an attempt to analyse the present-day tourist relationship between industrial nations and Developing Countries. It furthermore describes predictable conflict situations which may arise if these relations are subject to excessive physical and psychological strains or if the international division of labor in the field of “Vacation production” becomes unbalanced.     

The dynamics of emerging economy MNEs: How the internationalization process model can guide future research

The rapid emergence of multinational enterprises (MNEs) from emerging economies calls for a re-assessment of established theories of the MNE. We assess the usefulness of the internationalization process model (IPM), also known as the Uppsala model, to explain the recent strategies of emerging economy MNEs. We argue that popular stages models derived from the IPM are not helpful, but the underlying process of experiential learning driving steps of increased commitment is an important element in explaining the evolution of these MNEs over time. Focusing on the role of acquisitions within internationalization processes, we illustrate our arguments with six case studies of Thai MNEs. On this basis, we discuss how the IPM can inform future research on emerging economy MNEs. Specifically, the IPM suggests focusing on the internal and external factors that may induce firms to accelerate their cycle of international learning and commitment, in particular the roles of networks, acquisitions, human resources, big step commitments, the home country institutional environment, and possible managerial biases.     

Improving the effectiveness of nondisclosure agreements by strengthening concept learning

Intellectual property infringements rank among the top economic crimes, even though there are mechanisms in place to prevent their occurrence. One such mechanism are nondisclosure agreements, which, however, have been reported to fail in practice. This article argues that this may be overcome by strengthening employees’ concept learning. In an experiment, we investigated whether extended nondisclosure agreements, which provide the employee with detailed explanations and examples, lead to better recognition of trade secrets as compared to a standard nondisclosure agreement or no agreement at all. It was found that the extended nondisclosure agreement indeed increased participants’ ability to judge what falls under the trade secret law, whereas the standard nondisclosure agreement showed no such effect. Furthermore, the effects of the factors ‘Involvement’, ‘Specificity’, ‘Publicity’, and ‘Purpose’ on the identification of trade secrets could be proven experimentally. Employees’ judgments of whether an information represents a trade secret seem to rely on general cognitive processes. From this follows that concept learning could be integrated into systematic approaches for protecting intellectual property.     

Risk-managed industry momentum and momentum crashes

This paper investigates Barroso and Santa-Clara’s [J. Financ. Econ., 2008, 116, 111–120] risk-managed momentum strategy in an industry momentum setting. We investigate several traditional momentum strategies including that recently proposed by Novy-Marx [J. Financ. Econ., 2012, 103, 429–453]. We moreover examine the impact of different variance forecast horizons on average pay-offs and also Daniel and Moskowitz’s [J. Financ. Econ., 2016, 122, 221–247] optionality effects. Our results show in general that neither plain industry momentum strategies nor the risk-managed industry momentum strategies are subject to optionality effects, implying that these strategies have no time-varying beta. Moreover, the benefits of risk management are robust across volatility estimators, momentum strategies and subsamples. Finally, the ‘echo effect’ in industries is not robust in subsamples as the strategy works only during the most recent subsample.     

Key countries in the Third World

Present classifications of the developing countries are of limited usefulness as a basis for determining development policy priorities in the industrialised countries, argue our authors. They define a group of “key countries” which are of strategical importance for the world economy and outline the development risks facing these countries.¹ They suggest that the OECD countries would be better advised to follow a policy of cooperation with these key countries rather than the “man mind thyself” policies which are presently gaining in popularity.
