Abstract The present paper combines loss attitudes and linear utility by providing an axiomatic analysis of corresponding preferences
in a cumulative prospect theory (CPT) framework. In a sense we derive a two-sided variant of Yaari’s dual theory, i.e., nonlinear
probability weights in the presence of linear utility. The first important difference is that utility may have a kink at the
status quo, which allows for the exhibition of loss aversion. Also, we may have different probability weighting functions
for gains than for losses. We apply the model to both portfolio selection and insurance demand. Our results show that CPT
with linear utility has more realistic implications than the dual theory since it implies only a weakened variant of plunging.

Summary. We discuss a competitive (labor) market where firms face capacity constraints and individuals differ according to their productivity.
Firms offer two-dimensional contracts like wage and task level. Then workers choose firms and contracts. Workers might be
rationed if the number of applicants exceeds the capacity of the firm.
We show that under reasonable assumptions on the distribution of capacity an equilibrium in pure strategies (by the firms)
exists. This result stands in contrast to the case of unlimited capacity. The utility level is uniquely determined in equilibrium.
No rationing occurs in equilibrium, but it does off the equilibrium path.

Summary. I present an axiomatization of subjective expected utility and Bayesian updating in a conditional decision problem. This
result improves our understanding of the Bayesian standard from two perspectives: 1) it uses a set of axioms which are weak
and intuitive; 2) it provides a formal proof to results on the relation between dynamic consistency, expected utility and
Bayesian updating which have never been explicitly proved in a fully subjective framework.

The purpose of this study is to examine the effects of State regulation that determines the extent of professional independence of advanced practice nurses (APNs). We find that in States where APNs have acquired a substantial amount of professional independence, the earnings of APNs are substantially lower, and those of physicians assistants (PAs) are substantially higher, than in other States. These results are striking since PAs are in direct competition with APNs; the only real operational difference between these groups is that PAs are salaried employees who must work under the supervision of a physician. The implication is that physicians have responded to an increase in professional independence of APNs by hiring fewer APNs and more PAs. The finding that earnings of APNs decline when they attain more professional autonomy vis-à-vis physicians reinforces work by Sass and Nichols on physical therapists.The content is the responsibility of the authors and does

This paper empirically investigates the development of cross-country differences in energy- and labour productivity. The analysis
is performed at a detailed sectoral level for 14 OECD countries, covering the period 1970–1997. A σ-convergence analysis reveals
that the development over time of the cross-country variation in productivity performance differs across sectors as well as
across different levels of aggregation. Both patterns of convergence as well as divergence are found. Cross-country variation
of productivity levels is typically larger for energy than for labour. A β-convergence analysis provides support for the hypothesis
that in most sectors lagging countries tend to catch up with technological leaders, in particular in terms of energy productivity.
Moreover, the results show that convergence is conditional, meaning that productivity levels converge to country-specific
steady states. Energy prices and wages are shown to positively affect energy- and labour-productivity growth, respectively.
We also find evidence for the importance of economies of scale, whereas the investment share, openness and specialization
play only a modest role in explaining cross-country variation in energy- and labour-productivity growth.

We study the distribution of basic scientific research across countries and time, and explain the process that resulted in
the United States becoming the undisputed leader in basic research. Our study is based on the records of scientific awards,
and on the data of global economic trends. We investigate the degree to which scale/threshold effects account for the number
of prizes won. We constructed a stylized model, predicting a non-linear relationship with lagged relative GDP as an important
explanatory variable of a country’s share of prizes. Our empirical research findings find support for these predictions and
the presence of a “winner-takes-all” effect.

In 2003 Japan proposed a Climate Change Tax to reduce its CO2 emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the
revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions Prediction and
Policy Analysis (EPPA) model shows that this policy is unlikely to bring Japan into compliance with its Kyoto target unless
the subsidy encourages improvement in energy intensity well beyond Japan’s recent historical experience. Similar demand-management
programs in the US, where there has been extensive experience, have not been nearly as effective as they would need to be
to achieve energy efficiency goals of the proposal. The Tax proposal also calls for limits on international emission trading.
We find that this limit substantially affects costs of compliance. The welfare loss with full emissions trading is 1/6 that
when Japan meets its target though domestic actions only, the carbon price is lower, and there is a smaller loss of energy-intensive
exports. Japan can achieve substantial savings from emissions trading even under cases where, for example, the full amount
of the Russian allowance is not available in international markets. 相似文献

This paper examines the growth effects of intellectual property right (IPR) protection in a quality-ladder model of endogenous
growth. Stronger IPR protection, which reduces the imitation probability, increases the reward for innovation. However, stronger
protection also gradually reduces the number of competitive sectors, in which innovation is easier than in monopolistic sectors.
With free entry to R&D, the number of researchers in each remaining competitive sector increases, but the concentration of
R&D activity raises the possibility of unnecessary duplication of innovation, thereby hindering growth. Consequently, imperfect
rather than perfect protection maximizes growth. Welfare and scale effects are also examined. 相似文献
