Linking health plan performance with disability outcomes

Although the managed health care industry evolved and matured in the 1980s and 1990s, such initiatives to control disability costs failed to keep pace. As employers became aware of the costs of lost productivity, managed disability programs quickly evolved. This article discusses the trends, issues and assumptions in managed health and disability models, providing case studies to support the authors' hypothesis that health plans can have a direct impact on disability duration.     

Common labor market,attachment and spillovers in a large metropolis

In this paper, we extend the home-attachment model to a setting with multiple (more than two) jurisdictions and consider non-cooperative policy making for provision of different types of metropolitan public goods in the presence of a common labor market. Migration and working place choices are independent. We show that the optimal redistributive policy implemented by a central authority always yields equalization of private consumption levels across jurisdictions. This result holds whether or not policy makers are able to anticipate migration responses to their policy choices. In the decentralized leadership games, jurisdictions make choices that fully internalize externalities.     

Risk aversion under preference uncertainty

We show that if an agent is uncertain about the precise form of his utility function, his actual relative risk aversion may depend on wealth even if he knows his utility function lies in the class of constant relative risk aversion (CRRA) utility functions. We illustrate the consequences of this result for optimal asset allocation: poor agents that are uncertain about their risk aversion parameter invest less in risky assets than wealthy investors with identical risk aversion uncertainty.     

Domestic Climate Policies and the WTO

The Kyoto Protocol gives Annex 1 countries considerable flexibility in the choice of domestic policies to meet their emissions commitments. Possible climate policies include carbon/energy taxes, subsidies, energy efficiency standards, eco‐labels, and government procurement policies. In order to meet their targets with minimum adverse effects on their economies, Annex 1 governments with differentiated legal and political systems are highly likely to pursue these policies that may have the potential to bring them into conflict with their WTO obligations. This paper explores the potential interaction between these domestic climate policies and WTO rules. It argues that their potential conflicts can be avoided or at least minimised if WTO rules are carefully scrutinised, and efforts are made early on to ensure that the proposed climate policies comply with them. It suggests an early process of pursuing consultations between WTO members and the Parties to the Climate Change Convention and points to the need of further exploring ways to enhance synergies between the trade and climate regimes.     

The capital tax paradox in a greening economy

We adopt a simple model of endogenous growth with polluting capital and a fixed budget for aggregate emissions. Pollution abatement efficiency is growing over time due to technical progress. We find that long-run capital and consumption are inversely related to the initial capital stock. Capital taxation does not harm the economy but actually raises long-run consumption and production, which we call the “capital tax paradox.” The reason for this surprising result is that in an economy with a binding carbon policy, early abundance of polluting capital is not a blessing but a curse. It is preferable to have a large capital stock when abatement efficiency has grown sufficiently large. The paper also provides novel results on the impact of pollution intensity and the rate of technical progress on the greening of the economy and the pollution permit prices. In the quantitative part, we calibrate model and study economic growth under different assumptions on the basic model parameters.

     

The supply-of-immigrants function and taxation of immigrant's incomes: An econometric analysis

This paper considers the derivation of the commonly estimated macro supply-of-migrants equation from a discrete choice-of-location theory, in which tastes are stochastic. This approach highlights a number of economic and econometric problems inherent in popular forms of this equation. A logit specification of the supply function of U.S. immigrants is presented, using aggregated data on applications for labor certificates rather than observed movements. A modest simulation then follows, reporting the sensitivity of migration flows, hours worked by immigrants, and tax revenues, under alternative rates of Bhagwati's proposed tax on U.S. immigrant's incomes.     

Guidelines for marketing a new industrial product

This article presents an illustration of what evaluations and obstacles a new product can face in an industrial market. Guidelines are also suggested which will hopefully better prepare industrial marketers for more success in marketing new products.     

Efficacy of public awareness strategies for promoting existing cultural heritage tourism assets in Dar es Salaam

Although Dar es Salaam City is endowed with numerous cultural heritage resources, it fails to exploit such potentials. While there were some initiatives to boost cultural heritage tourism in the city, their efficacy was unknown and they remain undocumented. This study was designed to assess public awareness means and their effectiveness in promoting cultural heritage tourism in Dar es Salaam City. Data collection was through questionnaires, focus group discussions, observations, and key informant interviews. Findings indicated that most of the existing potential sites were not known as cultural heritage tourism sites such that they were regarded like any other normal places in the city. Available public awareness strategies (except a few) were ineffective and inaccessible. One could then wonder how available cultural heritage assets may be made known and attract others to take part. The study calls for public awareness strategies to improve knowledge on available cultural heritage assets to the general public, a measure, which will positively enhance accessibility to cultural heritage assets, improve goodwill as well as cooperation to tourists and improve ethics of their care. Such undertakings eventually will lead to sustainable cultural heritage tourism growth.
