Synopsis We describe the first effort at creating a global ex-vessel fish price database, which is required for understanding the economic
behavior of participants in the world’s fisheries. We demonstrate potential applications of the database by linking it to
a spatially defined catch database, which makes it possible to attach landed values to species in both time and space. This
is the first database available publicly where interested members of the public, researchers and managers can easily find
and access ex-vessel prices of the world’s major commercial fish species. Preliminary results indicate that the average real
price of a number of species have declined between 1950 and 2002. The estimated landed value of fish globally, in year 2000
dollars, was about US$24 billion in 1950. It increased steadily to about US$90 billion in the early 1970s, reached a peak
of US$100 billion at the end of the 1980s, and declined to about US$80 billion in 2000. The top 15 fishing countries cumulatively
account for 79% of total real landed value, with Japan leading, even though the value of its landings has been declining.

This paper addresses from an economic perspective the issue of global biodiversity conservation. It challenges the perception
that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock
of natural capital. Despite the existence of a plethora of international agreements there still seems to be a global ‘deficit
of care’ surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation. More
light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for
biodiversity conservation. However, actual expenditures are much lower than willingness to pay estimates recorded in the published
literature. Using the criteria that the ‘right’ amount of conservation effort is one where the marginal economic benefits
from conservation just equal the marginal costs of conservation, the paper explores the biodiversity conservation conundrum
and concluded that, on the available evidence, the world does not care too much about this natural capital stock and bequests
to future generations.

Recent application of the switching regression model to allocate workers into the primary and secondary labor markets is
considered to be the best solution to the classification problem of the empirical testing of the dual labor market theory.
In such models, normality of the error terms is assumed. This paper adopts the switching regression model to test the dual
labor market theory by assuming different distributions of the error terms. The test results strongly support the dual labor
market theory regardless of the assumption one makes about the error terms. However, the results indicate that different distribution
can lead to different percentage distributions of workers in the two segments. In particular, the normal distribution generates
more workers in the primary segment than the non-normal distributions. Therefore, care must be taken not to generalize the
type of industries or occupations that fall under the primary and secondary segments.

Earlier experimental evidence indicates that some decision makers under-invest in information when it is costly. This insight is applied to the cost–benefit analysis of the provision of data obtained by satellites. In fields like agriculture, remotely sensed information of great precision can be provided to additional farmers at minimal extra costs if a service for farmers with similar information needs is set up. Here, the tendency to under-invest in information asks for creative solutions by the private sector: bankers may work together with rational producers in setting up the information service and promoting it. However, if producers financial resources are insufficient, public intervention, in the form of a free information service may be necessary.The author would like to thank an anonymous referee, Stephan von Cramon-Taubadel, Sean Flynn, Daniel Heller, and Carlos Lenz and participants of the Lisbon Conference of the International Atlantic Economic Society, particularly Asatoshi Maeshiro, for helpful comments. 相似文献

Abstract. The aim of this paper is to estimate the effect of fertility on the decision of labour force participation of married females
in Spain, allowing for the existence of unobserved characteristics that affect both fertility and participation. We use a
pooling of five waves of the European Household Panel for Spain (1994–1998). Results indicate that not taking into account
the unobserved characteristics that affect both variables imposes on average a strong downward bias on the true effect of
fertility on participation. This bias is especially strong for highly educated females.

Summary. We examine how irreversible capital reduces the possibility of a duopoly to sustain implicit collusion by grim strategies,
when the product is homogenous and firms compete in quantities. Compared with the case of reversible capital, there are two
countervailing effects: Deviation from an existing collusion is less attractive, because capital once installed causes costs
forever. But the punishment will also be less severe due to the high capacity the deviating firm can build before punishment
starts. The last effect dominates, meaning that the commitment value of capital is negative for all firms. If capital is irreversible,
collusion breaks down for realistic magnitudes of interest rates.

Summary. I prove that the equilibrium set in a two-player game with complementarities, and totally ordered strategy spaces, is a sublattice

Many accounting educators believe that the student learning of accounting is better facilitated over a longer period of time, rather than a shorter period of time. This study examined the results of student performance in two introductory accounting courses, comparing student performance results of four-week summer classes with the results of traditional 16-week courses. In this research, the same professor taught the spring and summer ACC 201 courses, and two other professors taught both the spring and summer ACC 211 courses. Also held constant were the lecture material, course assignment, and test content. The results of the study indicate that in general, students taking introductory accounting over four weeks fare about as well as students who take introductory accounting over a traditional 16-week period. These results have potential importance beyond accounting education and provide support to universities offering more block courses to better serve individual student needs. 相似文献

Double Moral Hazard,Monitoring, and the Nature of Contracts 总被引:8,自引:0,他引:8

generalized double-sided moral-hazard model, with risk-averse parties who mutually monitor each other (to get a reasonable idea of outcome/effort).
The model considers trade-off between monitoring costs and moral hazard costs, which are endogenously determined by the extent
of monitoring.
Using this model, we formally prove a generalized version of Coase's conjecture – that the optimal contract minimizes the
agency and risk costs. We then show how varying assumptions about the feasibility or cost of monitoring of the outcome or
the worker's effort lead to different contracts being optimal. The analysis is then used to explain the nature of contracts
observed in practice under many different situations. We will give an explanation as to why industrial workers typically work
under wage contracts, while share contracts are common in agriculture and will explain why profit sharing is more common for
senior managers than for the production workers.
