This paper develops an approach to tighten the bounds on asset prices in an incomplete market by combining no-arbitrage pricing
and preference-based pricing, and the approach is applied to a call option in the absence of dynamic rebalancing. With the
no-arbitrage pricing, it is straightforward to obtain the initial bounds, which are too wide to be of practical uses. By accepting
that a representative agent exhibits risk aversion from a benchmark pricing kernel, it is possible to narrow the bounds considerably.
Using the unbiased minimax deviation implicit in the parameters, one can restrict further the set of reasonable values on
assets in incomplete markets. 相似文献

The seasonal patterns observed on Monday stock returns are still unexplained by different asset pricing models. We attempt
to fill this gap in the finance literature by using the Fama-French (Journal of Financial Economics 33:3–56, 1993) risk factors to explain the Monday seasonal. The results in the study show that Monday returns are explained by risk factors
such as the market return, the size of the firms, and the book-to-market ratios of firms. 相似文献

Non‐profit organizations often seek volunteers to help staff a fundraising event. In the present research, an experimental study assessed volunteering time decisions for a fundraising event following manipulations of opportunity cost valence, opportunity cost avoidability and question order involving donating time and donating money. Opportunity costs represent foregone alternatives sacrificed (e.g. working) when engaging in an activity (e.g. volunteering), with valence of the opportunity cost indicating the appeal (positive or negative) of the foregone alternative and avoidability of the opportunity cost suggesting how easy it would be to forgo the alternative. Prospective donors are often asked to consider both volunteering time and contributing money, and these two questions posed to individuals can be varied in terms of order. The results of the experiment revealed that individuals intended to volunteer the most time when an opportunity cost was negative and avoidable. The lowest time donation intentions occurred when an opportunity cost was positive and less avoidable with individuals also being asked about donating money prior to being asked to donate time. The results highlighted the importance to non‐profit firms of considering opportunity costs potential volunteers face and suggested care in structuring the order of questions involving time and money posed to those individuals.

In weak institutional settings, autocrats barter political and economic concessions for support to remain in power and extract
rents. Instead of viewing the favors’ beneficiaries, i.e. the elites, as an exogenous entity, we allow the king to decide
whom to coopt provided the subjects are heterogeneous in the potential support—their strength—they could bring to the regime.
While the ruler can select the elites on the basis of their personal characteristics, an alternative strategy consists in
introducing some uncertainty in the cooptation process. The latter strategy allows the king to reduce the clients’ cooptation
price since in the event of a revolution the likelihood of being included in the future body of elites is lower. We show that
weak rulers are more likely to coopt the society’s strongest individuals, while powerful rulers diversify the composition
of their clientele. Moreover, when agents value more future discounted outcomes, the king is more likely to randomly coopt
subjects. 相似文献

Local governments invest in public infrastructure to develop their regions. When they depend on intergovernmental grants for
local development and have opportunities to lobby upper-level governments for such grants, horizontal intergovernmental competition
in lobbying activity may emerge in addition to competition over public infrastructure. This paper empirically examines the
existence of these interactions between Japanese localities, by using data on the value of industrial parks as infrastructure
provisions and on personnel interchanges between the central and local governments as a measure of lobbying activity. Our
results suggest that a Japanese local government’s choice of the size of industrial parks and its invitation to central officers
to act as a director on loan are positive responses to the neighboring local government’s policy choices. As the value of
the industrial parks in a district is affected by the neighboring districts’ lobby activities and their industrial park values,
we can interpret these results as evidence of inter-regional competition in these two dimensions, rather than control by the
central government in this unitary state. 相似文献

A decision problem—allocating public research and development (R&D) funding—is faced by a planner who has ambiguous knowledge
of welfare effects of the various research areas. We model this as a reverse portfolio choice problem faced by a Bayesian
decision-maker. Two elements of the planner’s inferential system are developed: a conditional distribution of welfare ‘returns’
on an allocation, given stated preferences of citizens for the different areas, and a minimum risk criterion for re-allocating
these funds, given the performance of a status quo level of funding. A case study of Canadian public research funds expended
on various applications of agricultural biotechnology is provided. The decision-making methodology can accommodate a variety
of collective expenditure and resource allocation problems. 相似文献
