The Present International Monetary System: Problems,Complications, and Reforms

In the last decade serious crises have affected financial markets. Some proposals to avoid international financial crises have been made, but more useful could be measures to strengthen the functioning of the present international monetary system. Another way could be a much greater involvement of the private sector. The misalignment among leading currencies of the world can be a source of crisis difficult to solve. The creation of the European Central Bank (ECB) and of the euro leaves unresolved the serious problem of how a European Monetary Union member will respond to an asymmetric shock.     

Unawareness and bankruptcy: A general equilibrium model

Summary. We present a consistent pure-exchange general equilibrium model where agents may not be able to foresee all possible future contingencies. In this context, even with nominal assets and complete asset markets, an equilibrium may not exist without appropriate assumptions. Specific examples are provided. An existence result is proved under the main assumption that there are sufficiently many states that all the agents foresee. An intrinsic feature of the model is bankruptcy, which agents may involuntarily experience in the unforeseen states. Received: April 23, 1997; revised version: May 19, 1997     

Developing an integrated conceptual framework to understand biodiversity conflicts

Although biodiversity-related conflicts are generally embedded into an ecological, economic and social context, reported studies often focus on only one of these aspects. The practical facilitation of such conflicts typically adopts an equally restricted view. The developing field of biodiversity conflict management is thus fragmented and, due to its generally insular case study approach, lacks theoretical underpinning.     

“When Should Manufacturers Want Fair Trade?”: New Insights from Asymmetric Information when Supply Chains Compete

We study a model of competing manufacturer/retailer pairs where adverse selection and moral hazard are coupled with promotional externalities at the downstream level. In contrast to earlier models mainly focusing on a bilateral monopoly setting, we show that with competing brands a ‘laissez‐faire’ approach towards vertical price control might not always promote productive efficiency. Giving manufacturers freedom to control retail prices is more likely to harm consumers when retailers impose positive promotional externalities on each other, and the converse is true otherwise. Our simple model also suggests that, with competing supply chains, consumers and manufacturers might prefer different contractual modes if promotional externalities have substantial effects on demands.     

A stochastic model to evaluate pricing distortions in indemnity insurance methods for MTPL insurance

Direct compensation or the direct reimbursement scheme is an indemnity insurance method that many European and American countries use to manage motor liability claims in which the driver that suffers an accident is paid by his/her insurance company that possibly later receives a flat-rate reimbursement (known as forfeit). Using non-life actuarial methodologies, this article analyses the distortion effects due to the direct compensation mechanisms and the effects of different forfeit reimbursement systems on policyholder tariffs in the management of motor liability claims involving vehicles in two different sectors, i.e. automobile and motorcycle. We empirically analyse and formalize the distortion effects resulting from the mechanism that different direct reimbursement systems produce, and explore the correlation between increasing tariffs for motorcycle policyholders and decreasing tariffs for other vehicle policyholders. We propose some alternative methods to overcome these distortion effects, evaluating their pricing impact through a stochastic model applied to a case study.

     

A note on preference for flexibility

A result of Kreps (1979) on preference for flexibility is extended from two to three periods (formally from preferences over sets to preferences over sets of sets). An intuitively easier route to Kreps' original result is also presented, making the proof essentially ready for use in a decision theory class.

Market orientation as determinant of entrepreneurship: An empirical investigation on SMEs

Entrepreneurial Orientation (EO) and Market Orientation (MO) are considered key factors in ensuring firm longevity in the new competitive landscape. Despite extensive research during the past decade, most of the studies use samples that exclude small and medium enterprises (SMEs), which represent the majority of economic activity worldwide. Some studies do investigate this relationship in small companies but place little importance on the subtle differences between SMEs and large companies when measuring MO. This study empirically investigates the relationship between MO and EO on a sample of 2500 Swedish SMEs. A new measure of MO that takes into consideration SMEs specific conditions has been developed and used. Findings suggest that MO is the main determinant of EO in SMEs.
