Competitive risk sharing contracts with one-sided commitment

This paper analyzes dynamic equilibrium risk sharing contracts between profit-maximizing intermediaries and a large pool of ex ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex post. In any given period, after having observed her income, the agent can walk away from the contract, while the intermediary cannot, i.e. there is one-sided commitment. We consider the extreme scenario that the agents face no costs to walking away, and can sign up with any competing intermediary without any reputational losses. We demonstrate that not only autarky, but also partial and full insurance can obtain, depending on the relative patience of agents and financial intermediaries. Insurance can be provided because in an equilibrium contract an up-front payment effectively locks in the agent with an intermediary. We then show that our contract economy is equivalent to a consumption-savings economy with one-period Arrow securities and a short-sale constraint, similar to Bulow and Rogoff [1989. Sovereign debt: is to forgive to forget? American Economic Review 79, 43-50]. From this equivalence and our characterization of dynamic contracts it immediately follows that without cost of switching financial intermediaries debt contracts are not sustainable, even though a risk allocation superior to autarky can be achieved.     

Financial market stability—A test

This paper proposes a definition for financial market stability and an econometric test. It analyzes the impact of systematic and systemic shocks on developed and emerging market stock indices in normal and extreme market conditions. Financial market stability is defined as a constant impact of systematic shocks in normal and extreme market situations. Empirical results show that the impact of systematic shocks is significantly larger in extreme market conditions than in normal conditions for emerging markets. In contrast, the relationship is stable for developed markets. Hence, only developed markets meet an essential condition for financial market stability.

The dilemma of developing country research

Research in developing countries has so far suffered from a number of serious deficiencies regarding its applicability in practice. Professor Bronger analyses the various causes of this undesirable state of affairs and shows how developing country research can be more effectively attuned to its principal task of forming the scientific basis for development planning and development policy.     

A critique of the socio-cultural approach to development planning

Recent reflections on development policy have tried to eliminate the weak points in the economically oriented development theories which have dominated development planning up to now, and the traditional modernisation theories complementary to them. The propagation of strategies geared towards overcoming technological and cultural dependence is one result of such rethinking. The following article takes Black Africa as its case example for a critical appraisal of this “socio-cultural” approach.     

Transition probabilities in a problem of stochastic process switching

Extant solutions for state-contingent process switching use first-passage time densities or differential equations. We alternatively employ transition probabilities. These conditional likelihood functions also have obvious appeal for econometric analyses as well as derivative pricing and decision making under absorption and extinction.     

Administrative cooperation and disease control in cross-border pork production

In recent years, the continuous structural change in the value chain of modern food production has been characterised by an increasing international division of labour among manufacturing companies. A regional specialisation of primary agricultural production is especially apparent in meat production. Thus, the German–Dutch border area has developed into a region of unprecedented intensive pork production. While The Netherlands specialises in piglet production, the production of fattened pigs continues to grow in northwest Germany. As a result of this increasing transnational value chain development, German imports of Dutch piglets have risen continuously since 2000. However, this structural interweaving of pork production between The Netherlands and Germany has resulted in many new challenges for the cooperation between the various participants and in particular for the administrative authorities in the field of food and feed safety as well as efficient animal disease control. The motivation for this exploratory study stems from the lack of scientific work on this topic to date. The aim of this research is to illustrate the relevance of functioning cross-border cooperation in the food sector, using commodity flow structures and disease spread analysis. Results indicate that cross-border cooperation between authorities during a CSF epidemic can reduce the risk of recurrence and the duration by 50%.     

An investigation of the performance consequences of alignment and adaptability: contingency effects of decision autonomy and shared responsibility

This research investigates the moderating role of organizations’ structural context on the performance outcomes of the firm's alignment and adaptability pursuits. It focuses in particular on the role of decision autonomy and shared responsibility, and posits that these structural features exert opposing influences on the effect of alignment and adaptability on performance. Using a sample of more than 200 Canadian‐based firms, this study finds that at higher levels of decision autonomy, the positive relationship between alignment and performance becomes weaker, and the positive relationship between adaptability and performance becomes stronger. Furthermore, at higher levels of shared responsibility, the positive relationship between adaptability and performance strengthens. Thus, the study offers structure‐based explanations for the challenge that organizations face when they attempt to reap the benefits of alignment and adaptability simultaneously.
