We seek to isolate in the laboratory factors that encourage and discourage the sunk cost fallacy. Subjects play a computer
game in which they decide whether to keep digging for treasure on an island or to sink a cost (which will turn out to be either
high or low) to move to another island. The research hypothesis is that subjects will stay longer on islands that were more
costly to find. Eleven treatment variables are considered, e.g. alternative visual displays, whether the treasure value of
an island is shown on arrival or discovered by trial and error, and alternative parameters for sunk costs. The data reveal
a surprisingly small sunk cost effect that is generally insensitive to the proposed psychological drivers.

Green net national product was thought to be one way of measuring sustainable income. However, David Pearce understood that
a better measure of sustainable development was to look at what a generation is leaving in form of capital assets to later
generations. In this article, his arguments and insights are highlighted against recent theoretical advances. 相似文献

We hypothesize that the firm’s regulatory environment influences the sensitivity of its equity value to information. Using
intraday stock price data of utilities operating in differing regulatory environments we test for systematic differences between
the responsiveness of stock prices of utility firms operating in deregulated and regulated environments to a common information
set. Our findings reveal sharp differences in responses, with those of utilities operating in deregulated environments the
strongest, and the responses of utilities in highly regulated environments the weakest. While the evidence supports our hypothesis,
in a broader sense, the evidence suggests that deregulation aids in the process of price discovery. We also find evidence
that suggests that deregulation, per se, does not lead to higher stock price volatility.

We document the substantial process of structural transformation—the reallocation of labor between agriculture, manufacturing,
and services—and aggregate productivity growth undergone by Portugal between 1956 and 1995. We assess the quantitative role
of sectoral labor productivity in accounting for these processes. We calibrate a model of the structural transformation to
data for the United States and use the model to gain insight into the factors driving the structural transformation and aggregate
productivity growth in Portugal. The model implies that Portugal features low and roughly constant relative productivity in
agriculture and services (around 22%) and a modest but growing relative productivity in manufacturing (from 44 to 110%). We
find that productivity growth in manufacturing accounts for most of the reduction of the aggregate productivity gap with the
United States and that a further closing of this gap can only be accomplished via improvements in the relative productivity
of services.

This paper provides empirical evidence on regional labor market flexibility in Europe and, in particular, in the EU-accession
countries in Central and Eastern Europe. Whereas substantial regional disparities in unemployment are found for pre-accession
EU member countries as well as for accession countries, an empirical analysis taking account of spatial effects shows that
regional wage flexibility is significantly higher for accession countries. Moreover, unemployment disparities are found to
be less persistent in the accession countries.

In this paper, we propose an estimator for the population mean when some observations on the study and auxiliary variables
are missing from the sample. The proposed estimator is valid for any unequal probability sampling design, and is based upon
the pseudo empirical likelihood method. The proposed estimator is compared with other estimators in a simulation study. 相似文献

There are four traditional uses of private personal liability insurance dating from the 1970s to the present (Hayes 1979;
Sommers 2005) which pertain either to individuals or corporations. There is insurance to cover damage to rental cars, umbrella
insurance to cover any injury to a guest at one’s home, insurance bought by corporations to cover potential corporate responsibility
for actions of company representatives and insurance including misadventures with financial information and morally hazardous
behavior as well as corporate required actions which are later deemed to be wrong or inappropriate. Employees need to find
out if the employee manual provides for coverage for legal liabilities resulting out of performing job responsibilities. Due
to a need to reduce company costs, many companies are reducing or eliminating coverage for employees for many types of actions.
Private personal liability insurance gives you the peace of mind to know what you are covered for and for how long. Employee
rights versus corporate budgets are at the core of this discussion. 相似文献
